So I decided to go camping on my own, which I’d never done before. After throwing the sleeping bag and a few things to eat into the car, I was on my way. I was a little nervous about being alone. As soon as I reached the camping spot, I asked the guide if he thought I’d be all right camping alone. “Sure,” he said. His answer was somewhat reassuring (令人放心的). After supper, I got the fire started easily. Looking up, I couldn’t see much of the sky through the trees. Falling asleep quickly, I was awakened (吵醒) a few hours later by some noises. It sounded too loud. Thankfully, after a few minutes, it stopped. But I was scared the rest of the night. I didn’t think it was a good idea to go out and look at the star after all. As I lay there, I heard squirrel and an ow (猫头鹰) calling. I was somewhat glad I was awake to hear this sound of nature. The next morning, my neighbor talked about how a bear had visited in the night and knocked over some chairs. Luckily, the bear hadn’t done any more damage (损坏) than that. While I was disappointed at not seeing the shooting stars, I’m now a lot more confident ( 自信的) about camping by myself. Bear or no bear. 6．What made the writer go camping alone?

A．Sound of Nature B．Camping Creates Confidence C．Enjoying Meteor Shower D．A Wonderful Holiday in the Woods 3 A fireball lit up the sky on the evening of December 15th, 2022 in Zhejiang. Instead of making wishes on this outer space object, some people were frightened, as the fireball was described as moving at a very fast speed and very bright. The fireball was much brighter than the full moon. It was like a meteor (流星). The object was over 10 centimeters wide, and it may not burn out completely during its fall. It was time of Geminid meteor shower activity recently, so the object might come from it. The remains of the fireball were later found in the countryside. Expert Zheng Yongchun examined the remains and said that the meteorite (陨石) has great value in studying Earth’s early history. Scientists said that about 48. 5 tons of materials fall on Earth each day. Almost all the materials are vaporized (蒸发) in Earth’s atmosphere, leaving a bright trail called “shooting stars”. Several meteors per hour can usually be seen on any night, which are often called meteor showers. How does a meteor land on Earth? Meteoroids (流星体), often seen as space rocks, enter Earth’s atmosphere at high speed and burn up, then meteors occur. Only 5 percent of meteorites can make it to Earth’s surface, and these can range from the size of a pebble (鹅卵石) to a fist (拳头). Even knowing the science behind this alien event, you may still worry about the chances of being hit by a meteorite. According to UK media Mirror, the chance is very small—about one in 840, 000, 000. There is only one record of a person being hit by a meteorite , which took place in 1954 in the US. The meteor crashed through the window and landed on the “lucky” lady Ann Hodges. 11．Why didn’t people make wishes when the fireball appeared? ________ A．Because it wasn’t like a meteorite. B．Because it was too big. C．Because it moved too fast and was too bright. D．Because people didn’t like its shape. 12．What does the underlined word “occur” probably mean? ________ A．Knock. B．Disappear. C．Die. D．Appear. 13．Which of the following is NOT true about the fireball? ________ A．It was about 2 meters long. B．It was over 10 centimeters wide. C．It might come from Geminid meteor shower activity. D．It was much brighter than the full moon. 14．What is the main idea of the last paragraph? ________ A．How the meteor comes into being. B．The chances of being hit by a meteorite. C．The speed of the meteor. D．The events about aliens. 15．What can’t we know from the text? ________ A．Where does the fireball come from? B．How does a meteorite form? C．Why does the meteor have a trail? D．What can we see on the moon? 4 Since ancient times, human beings have looked up at the night sky. Comets (彗星) and meteors (流星) flying through the blackness were seen as signs from the gods. They were used to tell the future of human lives. In 2013, a meteorite shower hit an area in Russia. It injured around 1,200 people. In ancient times, this would have been a strange and terrible experience. Today, thought, science offers simple explanations for the occurrence (事件). Meteorites are small pieces of debris (碎片) that float around in space. Sometimes, they come near a planet, such as Earth. When they enter our atmosphere, they often heat up and become very bright. This is why they are sometimes called “fireballs”. They are usually made of metals, such as iron (铁), and other minerals (矿物). The Russian meteorites were stony, with iron making up 10 percent of them. Meteorite showers, such as that in Russia, happen when a large meteor enters the Earth’s atmosphere and, due to heat, breaks up into small parts. Most of these are very small — smaller than a grain of sand — and so don’t even make it to the ground. But others can cause a lot of damage. The meteor in Russia weighed 10 tons when it entered our atmosphere, and broke up about 20-30 miles (30-50 km) above ground. The sky was filled with bright lights and loud noises. Many windows were broken. The damage cost Russia around 206 million yuan. 16．What did people in ancient times think when they saw a meteorite shower? A．It was a wonderful sight. B．It was common in nature. C．They respected it as a god. D．They felt puzzled and scared. 17．Which of the following is NOT true about meteorites? A．They float around in space. B．They often heat up when entering Earth. C．There are fires around them. D．They are usually made of metals. 18．When a large meteor comes into the Earth’s atmosphere, ___________. ① meteorite showers happen② it breaks up into small pieces ③ it falls to the ground as whole④ it seldom causes serious damage A．①② B．①③ C．①④ D．②④ 19．Which topic does the story NOT talk about? A．How meteorite showers happen. B．How to stop meteorite showers. C．The meteorites in Russia. D．The damage meteorites can cause. 5 There are lots of objects that we see in the sky. During the day we see the sun. After the sunset in the evening, we see mostly the stars. Not all the lights in the sky that we see are really stars. Of course, we see the moon. Some of the other lights in the sky are planets(行星). Planets go around the sun like earth does. Sometimes we can see a shooting star. Shooting star looks like a star that is moving quickly across the sky. Some people believe that seeing a shooting star will bring them good luck. It's hard to find shooting star because they run fast. The correct name for shooting star is meteor(流星). Space has lots of little objects. These can be rocks in space from old planets. These objects can be very small, they are called meteorites(陨石). When meteorite gets close to the earth, it gets pulled towards the earth by gravity(重力). Earth is surrounded by atmosphere(大气层). Atmosphere is made up of air and clouds. Meteorite burns in the earth's atmosphere. This makes the short bright moving light in the night sky. A meteorite then turns into meteor. 20．At night the sky is filled mostly with ________. A．the moon B．the planets C．the stars D．the sun 21．From the passage, we can know ________. A．all the lights in the sky that we see are really stars B．space has lots of little objects and they can be rocks from old planets. C．when a meteorite is near the earth, it gets pushed from the earth by gravity. D．shooting star looks like star that is moving slowly across the sky. 22．How does a meteorite turn into a meteor? Please put the following sentences in order. ①It is pulled towards the earth by gravity. ②The burning gives off bright light. ③A meteorite gets close to the earth. ④It burns in the earth's atmosphere. A．③④②① B．③④①② C．③①④② D．③②①④ 23．Where can we probably read this passage? A．In a diary. B．In a science magazine. C．In an advertisement. D．In a novel. 6 Have you ever seen a streak (条纹) of light flash across the night sky? You might call it a shooting star. Scientists call it a meteor. A meteor is something that falls through the earth’s atmosphere (the air around the earth) and has a burning long tail. Usually, meteors are rocks that burn (燃烧) up as they fall. As they burn, the rocks shine brightly. Most meteors burn up quickly in the atmosphere and never hit the ground. But if a meteor does fall down to the ground it is called a meteorite, this doesn’t happen very often but can one day bring the end of world. The rocks that we see as meteors come from different places of space. Scientists call these rocks meteoroids. Like planets, meteoroids travel in space, but they are much smaller than planets. Most meteoroids travel very far from the earth and we don’t see them. However, some meteoroids can travel very close to us and get in the way of the earth. Gravity (重心) then pulls them through the earth’s atmosphere, turning them into the meteors that you see in the night sky. The largest meteorite ever found in the United States is the Willamette Meteorite. This rock got here thousands of years ago. Today, you can see the 15, 000-kilogram meteorite at the American Museum of Natural History in New York City. It has been on show there since 1906. 24．According to the passage, a meteor is a kind of ________. A．burning tail B．bright fire C．burning rock D．traveling planet 25．Willamette Meteorite is famous because it’s the ________ one found in America.

C．Meteoroids are much smaller than planets. D．We can see the meteoroids in the sky. 27．We may read this passage in a ________. A．history book B．space fiction C．traveling guide D．science magazine 28．The purpose of this passage is to ________. A．encourage more people to study about the planets B．introduce some flying objects falling from space C．tell people the danger of light streaking in the sky D．show something about the American Museum of Natural History 7 There are lots of objects that we see in the sky. During the day we see the sun. After the sunset in the evening, we see mostly the stars. Not all the lights in the sky that we see are really stars. Of course, we see the moon. Some of the other lights in the sky are planets. Planets revolve (转动) around the sun like earth does. Once in a while someone will see what they call a shooting star. Shooting star looks like a star that is moving quickly across the sky. Some people believe that seeing a shooting star will bring them good luck. It’s hard to find shooting star because they disappear fast. The correct name for a shooting star is meteor. Besides very large objects like stars, planets and moons, space has lots of little objects. These can be rocks in space left over from old planets. These objects can even be as small as dust.These objects are called meteorites(陨石 ). When a meteorite gets close to the earth, it gets pulled towards the earth by gravity. Earth is surrounded by atmosphere. Atmosphere is made up of air and clouds. A meteorite blows up in the earth’s atmosphere. This makes the short bright moving light in the night sky. A meteorite thus turns into a meteor. 29．At night the sky is filled mostly with ______. A．the moon B．the stars C．the planets D．the sun 30．From the passage, we can know________. A．all the lights in the sky that we see are really stars. B．shooting star looks like a star that is moving slowly across the sky. C．when a meteorite is near the earth, it gets pushed from the earth by gravity. D．space has lots of little objects and they can be rocks left over from old planets. 31．How does a meteorite turn into a meteor? Please put the following sentences in order. ①The blowup gives off bright light. ② It is pulled towards the earth by gravity. ③A meteorite gets close to the earth. ④It blows up in the earth’s atmosphere. A．③④②① B．③④①② C．③②④① D．③②①④ 32．Where can we probably read this passage? A．In a science magazine. B．In a diary. C．In an advertisement. D．In a novel. 8 Have you ever seen light flash across the night sky? You might call it a shooting star while scientists call it a meteor(流星). A meteor falls through the earth’s atmosphere(the air around the earth) and has burning long tail. Usually, meteors are rocks that burn(燃烧) up as they fall. As meteors burn, they look bright. Most meteors burn up quickly in the atmosphere and never hit the ground. But if a meteor falls down to the ground, it becomes a meteorite(陨石). This doesn’t happen very often but may bring the end of the world. The meteors come from different places of space. Scientists call these rocks meteoroids(流星体). Like planets, meteoroids travel in space, but they are much smaller than planets. Most meteoroids travel very far from the earth and we don’t see them. However, some meteoroids can travel very close to us and get in the way of the earth.

B．Meteoroids are much smaller than planets. C．A meteorite can’t bring the end of the world. D．We can see the meteoroids in the sky every day. 35．Willamette Meteorite is the ________ meteorite. A．largest B．fastest C．heaviest D．oldest 9 When you are about to do something brave, a cheerful wish of “Good luck!” from a friend can be helpful. But if you think you need lots of luck, what else might you do? In the UK and US there are some strange traditions for bringing yourself a little more good luck. Some are hundreds of years old and some are much newer. Have you heard the saying “When you wish upon a star”? If you are looking up at the sky on a clear night and you see a sudden flash of light, it is probably a shooting star（流星）! Seeing one doesn’t happen very often. The saying goes that if you see one you have been very lucky, and so if you make a wish, it will come true. Maybe you have heard of the lucky rabbit’s foot. Some people believe that rabbits are lucky animals, so they carry a part of the rabbit, its foot, for good luck. There are all kinds of strange, unclear rules about which of the rabbit’s feet is the luckiest. It is said that this good luck tradition is the oldest one of all. However, as the funny saying goes, “Depend on the rabbit’s foot if you will, but remember it didn’t work for the rabbit!” People in Britain love trees. If it is autumn and leaves are falling from the trees, some people try to catch them as they fall because they think each leaf they catch will bring them a lucky month in the following year—they will need to catch 12 falling leaves to have a whole year of good luck! 36．What will happen when you see a shooting star? A．The wish will come true. B．People will watch falling leaves. C．The rabbit will bring you good luck. D．People will do something brave. 37．According to the article, we know that ________. A．leaves fall from the trees in a whole year B．the rabbit’s foot is the oldest luck tradition C．people believe that it’s unlucky to plant trees D．people can see a shooting star on a rainy night 38．Why do British people try to catch 12 falling leaves? A．Because the leaves can bring them a lucky month. B．Because leaves are falling in the season of autumn. C．Because there are so many leaves for them to catch. D．Because they want to have a whole year of good luck. 39．In Paragraph 5, the underlined word “them” refers to ________. A．rabbits B．animals C．leaves D．feet 10 The planets aren’t the only wanderers(漫游者) of the sky. There’re some things even farther and longer. Long after people were no longer afraid of planets, they still thought the comets(彗星) were bad objects that traveled in the sky. They were afraid that the comets would suddenly land on the earth and hurt them. But, in fact, even if a comet did hit the earth, nothing much happened. A comet is really a harmless （无害的）thing. Comets have round heads and long tails , and they are very bright. Sometimes they look like heads with long hair flying with them. That’s why they’re called comets. Comet means long-haired. Like the stars and planets, comets are far away. But we can know its size. The head of a small comet is as wide as the Pacific Ocean. And a big comet’s head is ten times as big as the earth. Its tail is millions of kilometers long. Then why wouldn’t the great big thing hurt us if it hit the earth? Because it isn’t solid. It’s thin like cloud. Its tail is nothing but bright gas. And its head is made of small pieces and they could not hurt the earth. Some comets can be seen for a few months. Then they go away. Some of them come back in a certain number of years. Some are never seen again. Perhaps these comets that never return have broken into pieces. For some think that shooting stars(流星) are pieces of broken comets. 40．People were afraid ________. A．comets are different from planets B．comets travel in the sky C．comets are much bigger than the earth D．comets could hit the earth 41．Comets have long tail like ________, so we call them comets. A．long hair B．round heads C．round dishes D．wide wings 42．From the passage we know the tails of comets are made of  ________. A．water B．solid C．gas D．small stones 43．The underlined word “astronomers” may mean ________ in Chinese. A．心理学家 B．艺术家 C．天文学家 D．考古专家 44．Which of the following is TRUE ? A．A comet is a kind of planets. B．Comets are all ten times as big as the earth. C．People can hardly see comets. D．Shooting stars may come from the broken comets. 11 阅读填空 Every August, bright lights dart (划) across the night sky. Some people call them shooting stars. But they’re not stars at all. These beautiful sights are meteors (流星). You can see them for yourself. An Ideal Time The Perseids are one of the busiest meteor showers of the year. In August you can see 60 or more meteors in an hour. The Perseids are easiest to see when the Moon isn’t out because its light washes out many meteors. You don’t need anything to help you see them. And you don’t need to know where Perseus is because meteors appear all over the sky. To see the most meteors each year, you need to find a dark place. Streetlights also wash out meteors. In many areas, a backyard might be perfect. Ask an adult to be with you and keep awake into night. In most cases, meteor showers aren’t early. Getting Ready Before you go out, it might be a good idea to put on mosquito repellent (驱蚊液). Put on warm clothes because you won’t be moving around much. A blanket might help keep you warm and protect you from mosquitoes. Take a flashlight (手电筒) with you. A flashlight that gives off red light is the best as red light doesn’t harm your ability to see in the dark as much as other colors do. And now is for the fun part. Go outside, sit in a chair, and look at whatever part of the sky is the darkest. Make sure trees and clouds aren’t blocking your view. Avoid looking at any light. Over the next half hour, your eyes will get used to the dark, and you’ll see your first meteor if you are lucky. Title: Tips for seeing meteors When is an ideal time? In August the Perseids appear most often and they are all over the sky. The Perseids are easy to see unless the Moon, as well as streetlights, 45 you seeing them. Invite a grown­up to stay up late with you, because meteors are 46 early. 47 can we get ready? Put on mosquito repellent and get dressed warmly. A blanket would help too. Take a flashlight with red light so that you can see in the dark more 48 . Go out and find an open space. With a little 49 you can see them after your eyes are used to the dark. 学科网（北京）股份有限公司 $$2024-2025学年九年级英语阅读热点话题(通用版) 2024-2025学年九年级英语阅读热点话题(通用版) 07.认识流星雨的形成 1 Amazing Chopsticks Scientists from the USA invented a special pair of chopsticks.

The meteor in Russia weighed 10 tons when it entered our atmosphere, and broke up about 20-30 miles (30-50 km) above ground. The sky was filled with bright lights and loud noises. Many windows were broken. The damage cost Russia around 206 million yuan. 16．What did people in ancient times think when they saw a meteorite shower? A．It was a wonderful sight. B．It was common in nature. C．They respected it as a god. D．They felt puzzled and scared. 17．Which of the following is NOT true about meteorites? A．They float around in space. B．They often heat up when entering Earth. C．There are fires around them. D．They are usually made of metals. 18．When a large meteor comes into the Earth’s atmosphere, ___________. ① meteorite showers happen② it breaks up into small pieces ③ it falls to the ground as whole④ it seldom causes serious damage A．①② B．①③ C．①④ D．②④ 19．Which topic does the story NOT talk about? A．How meteorite showers happen. B．How to stop meteorite showers. C．The meteorites in Russia. D．The damage meteorites can cause. 5 There are lots of objects that we see in the sky. During the day we see the sun. After the sunset in the evening, we see mostly the stars. Not all the lights in the sky that we see are really stars. Of course, we see the moon. Some of the other lights in the sky are planets(行星). Planets go around the sun like earth does. Sometimes we can see a shooting star. Shooting star looks like a star that is moving quickly across the sky. Some people believe that seeing a shooting star will bring them good luck. It's hard to find shooting star because they run fast. The correct name for shooting star is meteor(流星). Space has lots of little objects. These can be rocks in space from old planets. These objects can be very small, they are called meteorites(陨石). When meteorite gets close to the earth, it gets pulled towards the earth by gravity(重力). Earth is surrounded by atmosphere(大气层). Atmosphere is made up of air and clouds. Meteorite burns in the earth's atmosphere. This makes the short bright moving light in the night sky. A meteorite then turns into meteor. 20．At night the sky is filled mostly with ________. A．the moon B．the planets C．the stars D．the sun 21．From the passage, we can know ________. A．all the lights in the sky that we see are really stars B．space has lots of little objects and they can be rocks from old planets. C．when a meteorite is near the earth, it gets pushed from the earth by gravity. D．shooting star looks like star that is moving slowly across the sky. 22．How does a meteorite turn into a meteor? Please put the following sentences in order. ①It is pulled towards the earth by gravity. ②The burning gives off bright light. ③A meteorite gets close to the earth. ④It burns in the earth's atmosphere. A．③④②① B．③④①② C．③①④② D．③②①④ 23．Where can we probably read this passage? A．In a diary. B．In a science magazine. C．In an advertisement. D．In a novel. 6 Have you ever seen a streak (条纹) of light flash across the night sky? You might call it a shooting star. Scientists call it a meteor. A meteor is something that falls through the earth’s atmosphere (the air around the earth) and has a burning long tail. Usually, meteors are rocks that burn (燃烧) up as they fall. As they burn, the rocks shine brightly. Most meteors burn up quickly in the atmosphere and never hit the ground. But if a meteor does fall down to the ground it is called a meteorite, this doesn’t happen very often but can one day bring the end of world. The rocks that we see as meteors come from different places of space. Scientists call these rocks meteoroids. Like planets, meteoroids travel in space, but they are much smaller than planets. Most meteoroids travel very far from the earth and we don’t see them. However, some meteoroids can travel very close to us and get in the way of the earth. Gravity (重心) then pulls them through the earth’s atmosphere, turning them into the meteors that you see in the night sky. The largest meteorite ever found in the United States is the Willamette Meteorite. This rock got here thousands of years ago. Today, you can see the 15, 000-kilogram meteorite at the American Museum of Natural History in New York City. It has been on show there since 1906. 24．According to the passage, a meteor is a kind of ________. A．burning tail B．bright fire C．burning rock D．traveling planet 25．Willamette Meteorite is famous because it’s the ________ one found in America.

C．Meteoroids are much smaller than planets. D．We can see the meteoroids in the sky. 27．We may read this passage in a ________. A．history book B．space fiction C．traveling guide D．science magazine 28．The purpose of this passage is to ________. A．encourage more people to study about the planets B．introduce some flying objects falling from space C．tell people the danger of light streaking in the sky D．show something about the American Museum of Natural History 7 There are lots of objects that we see in the sky. During the day we see the sun. After the sunset in the evening, we see mostly the stars. Not all the lights in the sky that we see are really stars. Of course, we see the moon. Some of the other lights in the sky are planets. Planets revolve (转动) around the sun like earth does. Once in a while someone will see what they call a shooting star. Shooting star looks like a star that is moving quickly across the sky. Some people believe that seeing a shooting star will bring them good luck. It’s hard to find shooting star because they disappear fast. The correct name for a shooting star is meteor. Besides very large objects like stars, planets and moons, space has lots of little objects. These can be rocks in space left over from old planets. These objects can even be as small as dust.These objects are called meteorites(陨石 ). When a meteorite gets close to the earth, it gets pulled towards the earth by gravity. Earth is surrounded by atmosphere. Atmosphere is made up of air and clouds. A meteorite blows up in the earth’s atmosphere. This makes the short bright moving light in the night sky. A meteorite thus turns into a meteor. 29．At night the sky is filled mostly with ______. A．the moon B．the stars C．the planets D．the sun 30．From the passage, we can know________. A．all the lights in the sky that we see are really stars. B．shooting star looks like a star that is moving slowly across the sky.

A．③④②① B．③④①② C．③②④① D．③②①④ 32．Where can we probably read this passage? A．In a science magazine. B．In a diary. C．In an advertisement. D．In a novel. 8 Have you ever seen light flash across the night sky? You might call it a shooting star while scientists call it a meteor(流星). A meteor falls through the earth’s atmosphere(the air around the earth) and has burning long tail. Usually, meteors are rocks that burn(燃烧) up as they fall. As meteors burn, they look bright. Most meteors burn up quickly in the atmosphere and never hit the ground. But if a meteor falls down to the ground, it becomes a meteorite(陨石). This doesn’t happen very often but may bring the end of the world. The meteors come from different places of space. Scientists call these rocks meteoroids(流星体). Like planets, meteoroids travel in space, but they are much smaller than planets. Most meteoroids travel very far from the earth and we don’t see them. However, some meteoroids can travel very close to us and get in the way of the earth. Gravity(重心) then pulls them through the earth’s atmosphere, turning them into the meteors that you see in the night sky. The largest meteorite is in the United States. It is the Willamette Meteorite. This rock got here thousands of years ago. Today, you can see the 15,000-kilogram meteorite at the American Museum of Natural History in New York City. It has been on show there since 1906. 33．According to the passage, a meteor is a kind of ________.

A．largest B．fastest C．heaviest D．oldest 9 When you are about to do something brave, a cheerful wish of “Good luck!” from a friend can be helpful. But if you think you need lots of luck, what else might you do? In the UK and US there are some strange traditions for bringing yourself a little more good luck. Some are hundreds of years old and some are much newer. Have you heard the saying “When you wish upon a star”? If you are looking up at the sky on a clear night and you see a sudden flash of light, it is probably a shooting star（流星）! Seeing one doesn’t happen very often. The saying goes that if you see one you have been very lucky, and so if you make a wish, it will come true. Maybe you have heard of the lucky rabbit’s foot. Some people believe that rabbits are lucky animals, so they carry a part of the rabbit, its foot, for good luck. There are all kinds of strange, unclear rules about which of the rabbit’s feet is the luckiest. It is said that this good luck tradition is the oldest one of all. However, as the funny saying goes, “Depend on the rabbit’s foot if you will, but remember it didn’t work for the rabbit!” People in Britain love trees. If it is autumn and leaves are falling from the trees, some people try to catch them as they fall because they think each leaf they catch will bring them a lucky month in the following year—they will need to catch 12 falling leaves to have a whole year of good luck! 36．What will happen when you see a shooting star? A．The wish will come true. B．People will watch falling leaves. C．The rabbit will bring you good luck. D．People will do something brave. 37．According to the article, we know that ________. A．leaves fall from the trees in a whole year B．the rabbit’s foot is the oldest luck tradition C．people believe that it’s unlucky to plant trees D．people can see a shooting star on a rainy night 38．Why do British people try to catch 12 falling leaves? A．Because the leaves can bring them a lucky month. B．Because leaves are falling in the season of autumn. C．Because there are so many leaves for them to catch. D．Because they want to have a whole year of good luck. 39．In Paragraph 5, the underlined word “them” refers to ________. A．rabbits B．animals C．leaves D．feet 10 The planets aren’t the only wanderers(漫游者) of the sky. There’re some things even farther and longer. Long after people were no longer afraid of planets, they still thought the comets(彗星) were bad objects that traveled in the sky. They were afraid that the comets would suddenly land on the earth and hurt them. But, in fact, even if a comet did hit the earth, nothing much happened. A comet is really a harmless （无害的）thing. Comets have round heads and long tails , and they are very bright. Sometimes they look like heads with long hair flying with them. That’s why they’re called comets. Comet means long-haired. Like the stars and planets, comets are far away. But we can know its size. The head of a small comet is as wide as the Pacific Ocean. And a big comet’s head is ten times as big as the earth. Its tail is millions of kilometers long. Then why wouldn’t the great big thing hurt us if it hit the earth? Because it isn’t solid. It’s thin like cloud. Its tail is nothing but bright gas. And its head is made of small pieces and they could not hurt the earth. Some comets can be seen for a few months. Then they go away. Some of them come back in a certain number of years. Some are never seen again. Perhaps these comets that never return have broken into pieces. For some think that shooting stars(流星) are pieces of broken comets. 40．People were afraid ________. A．comets are different from planets B．comets travel in the sky C．comets are much bigger than the earth D．comets could hit the earth 41．Comets have long tail like ________, so we call them comets. A．long hair B．round heads C．round dishes D．wide wings 42．From the passage we know the tails of comets are made of  ________. A．water B．solid C．gas D．small stones 43．The underlined word “astronomers” may mean ________ in Chinese. A．心理学家 B．艺术家 C．天文学家 D．考古专家 44．Which of the following is TRUE ? A．A comet is a kind of planets. B．Comets are all ten times as big as the earth. C．People can hardly see comets. D．Shooting stars may come from the broken comets. 11 阅读填空 Every August, bright lights dart (划) across the night sky. Some people call them shooting stars. But they’re not stars at all. These beautiful sights are meteors (流星). You can see them for yourself. An Ideal Time The Perseids are one of the busiest meteor showers of the year. In August you can see 60 or more meteors in an hour. The Perseids are easiest to see when the Moon isn’t out because its light washes out many meteors. You don’t need anything to help you see them. And you don’t need to know where Perseus is because meteors appear all over the sky. To see the most meteors each year, you need to find a dark place. Streetlights also wash out meteors. In many areas, a backyard might be perfect. Ask an adult to be with you and keep awake into night. In most cases, meteor showers aren’t early. Getting Ready Before you go out, it might be a good idea to put on mosquito repellent (驱蚊液). Put on warm clothes because you won’t be moving around much. A blanket might help keep you warm and protect you from mosquitoes. Take a flashlight (手电筒) with you. A flashlight that gives off red light is the best as red light doesn’t harm your ability to see in the dark as much as other colors do. And now is for the fun part. Go outside, sit in a chair, and look at whatever part of the sky is the darkest. Make sure trees and clouds aren’t blocking your view. Avoid looking at any light. Over the next half hour, your eyes will get used to the dark, and you’ll see your first meteor if you are lucky. Title: Tips for seeing meteors When is an ideal time? In August the Perseids appear most often and they are all over the sky. The Perseids are easy to see unless the Moon, as well as streetlights, 45 you seeing them. Invite a grown­up to stay up late with you, because meteors are 46 early. 47 can we get ready? Put on mosquito repellent and get dressed warmly. A blanket would help too. Take a flashlight with red light so that you can see in the dark more 48 . Go out and find an open space. With a little 49 you can see them after your eyes are used to the dark. 参考答案 1 1．D 2．D 3．A 4．B 5．A 【解析】本文主要介绍了一种新发明的筷子、人造流星雨、机器人恐龙以及衣服上带有二维码的猫服务员。 1．细节理解题。根据“The chopsticks work by sending weak electricity to people’s tongues.
