Let's learn from astronauts who have been to space. Astronauts live and work in a special place called the International Space Station (ISS). It travels around the Earth at a very high speed.The iss is about the size of a football field.Inside,there are living rooms,laboratories and exercise areas. Life on the ISS is very different from life on Earth.Because there is almost no gravity, astronauts float everywhere.They have to tie themselves to walls to sleep.They use special sleeping bags that can be fixed to the wall.Food also floats,so astronauts eat from special bags.They cannot use plates or bowls because the food would float away Water is very important in space.Astronauts cannot take a shower like on Earth because water would float into the air.Instead,they use wet cloths to clean themselves.Drinking water comes from recycled water,including water from breath and sweat (F).Though it sounds strange,the water is very clean. Exercise is a must for astronauts.Without gravity,their muscles and bones get weak easily.So they exercise for about two hours every day.They use special machines to run and lift weights.This helps their bodies stay healthy. Astronauts also do science experiments on the ISS.They study how plants grow without gravity and how the human body changes in space.These experiments help us prepare for longer trips to the Moon and Mars in the future. Working in space is hard but exciting.Astronauts say the best part is looking at the Earth from space.They can see the blue oceans,green forests and white clouds.Some astronauts say they feel a special love for our planet when they see it from far away. ()1.Why can't astronauts use plates or bowls to eat in space? A.Because they don't have enough space. B.Because the food would float away. C.Because they prefer to eat from bags. D.Because plates are too heavy in space. ()2.How do astronauts get drinking water on the ISS? A.They bring a lot of water from Earth. B.They collect rain in space. C.They recycle water from their bodies D.They use special machines to make water. ()3.What does the underlined word "must"in Paragraph 4 probably mean? A.Something that is enjoyable B.Something that is necessary. C.Something that is difficult D.Something that is interesting. ()4.What is the best title for this passage? A.How to Become an Astronaut B.Life on the Space Station C.The History of Space Travel D.Fun Experiments in Space ()5.According to the passage,what is the best part of working in space for astronauts? A.Doing science experiments. B.Exercising for two hours every day. C.Looking at the Earth from space. D.Eating from special bags. B篇 Have you ever wondered what it would be like to travel to Mars?A group of scientists are working on a plan to send people there by 2040.But it is not an easy job. First,the trip to Mars takes a long time.A spaceship needs about seven months to travel from Earth to Mars.That means astronauts will spend nearly a year just going there and coming back.They need to bring enough food,water and air for the whole trip. Second,Mars has a very thin atmosphere ()This means there is almost no air to breathe.The temperature on Mars is also very cold,mostly around-60C.So astronauts cannot go outside without special spacesuits.These suits must keep them warm and give them oxygen. Third,the gravity on Mars is only about one-third of that on Earth.A person who weighs 60 kilograms on Earth would weigh only about 20 kilograms on Mars.This sounds fun because you can jump higher and carry heavier things.But low gravity can also make your muscles and bones weak over time. Scientists also worry about space radiation().In space,there is a lot of radiation from the sun and other stars.On Earth,the atmosphere protects us,but in space or on Mars,there is much less protection.Too much radiation is bad for the human body and can cause illness. Despite all these problems,many scientists believe we can do it.They are working on new technologies every day.Some are building stronger spaceships.Others are finding ways to grow food on Mars.A few even think about building houses under the ground to stay safe from radiation. Would you like to be one of the first people to live on Mars?It will be dangerous and difficult,but also very exciting.Maybe one day,humans will have two homes:Earth and Mars. ()1.How long does it take to travel from Earth to Mars? A.About one year. B.About seven months. C.About three days D.About two weeks. ()2.Why do astronauts need special spacesuits on Mars? A.To help them breathe and keep warm B.To make them look cool. C.To help them jump higher. D.To protect them from animals. ()3.How much would a 90-kilogram person weigh on Mars? A.90 kilograms. B.60 kilograms. C.30 kilograms. D.20 kilograms. ()4.What is a problem that scientists worry about besides the trip time,thin air and low gravity? A.Lack of food. B.Space radiation. C.Too much exercise D.No water on Mars. ()5.What is the writer's attitude towards living on Mars? A.It is impossible. B.It is too dangerous to try. C.It is a dream that may come true D.It is a waste of time and money. 二、完形填空 Dear Diary, Today is 15 October 2053.I am sitting in the spaceship,looking out of the window at the stars.Tomorrow morning,we will 1.on the Moon!I can hardly believe it.

Sally Ride was born in 1951 in Los Angeles,California.When she was young,she loved science and sports.She was good at tennis and even thought about becoming a professional tennis player.But her love for science was stronger.She studied physics and later got a PhD(博士学位)from Stanford University. ln1978,NASA(美国国家航空航天局)was looking for new astronauts for the first time in ten years.More than 8,000 people applied )but only 35 were chosen.Sally Ride was one of them.She trained very hard for five years. On June 18,1983,Sally Ride made history.She flew into space on the space shuttle Challenger.She was 32 years old.During the six-day trip,she helped put satellites into space and did science experiments.Her job was to use a robotic arm to help do the work. After her first space trip,Sally Ride went to space again in 1984.In total,she spent more than 343 hours in space.She left NASA in 1987 and became a teacher.She started programs to help girls and young women study science and math.She wrote several science books for children,too. Sally Ride once said,"All adventures,especially into new territory,are scary ). But she also believed that facing fear was the first step to success.She died in 2012 at the age of 61.People will always remember her as a pioneer and a hero. 1.When was Sally Ride born? 2.What did Sally Ride do on her first space trip? 3.How many times did Sally Ride go to space in total? 4.According to the passage,what did Sally Ride do after leaving NASA? 5.What do you think we can learn from Sally Ride's story? 四、短文填空 用方框中所给单词的适当形式填空，使短文完整正确。（每个单词限用一次，每空限填一个单 词。) weigh,leave,breathe,collect,dream,experiment,program,surface,prepare,adventure Dear Zhao Wei, Hi!I'm very glad to receive your email.You asked me about my recent (life.
