It lies in the south of Anhui Province. Every year, thousands of visitors from different places travel there to enjoy its amazing natural beauty. Nowadays, we have two great ways to visit the Yellow Mountain: online tours and real trips. Taking an online tour is easy and convenient. We can sit in front of the screen and watch clear videos about the mountain. We can enjoy strange rocks, lovely pine trees and the wonderful sea of clouds without going out. We can also learn about its long history and special culture from the online guide. It saves much time and money, and we can visit it at any time we like. However, many people still like real trips better. When they climb the mountain by themselves, they can touch the green plants, feel the cool wind and take nice photos with their families. They can stop walking anytime to enjoy the fantastic views around them. It makes them feel relaxed and close to nature. It is also a good way to take exercise and stay healthy. Both ways are helpful and interesting. Online tours help us know more about the Yellow Mountain easily, and real trips bring us real fun and great memories. Which way of visiting would you like to choose? 1．Where is the Yellow Mountain? A．In the north of China. B．In the south of Anhui. C．Near Beijing.

B Millions of years ago, dinosaurs controlled the earth. And there were different kinds of dinosaurs on earth. Some of them were no bigger than chickens,while some were about 90 feet long. But all of them had very small brains. Later on, there weren’t any dinosaurs. What happened to them? In the days of dinosaurs, the whole earth was warm and wet. There were many green forests. But the earth changed slowly all the time. When parts of the earth became freezing and dry, the forests there died. Then dinosaurs could not find enough food to eat. This must be one reason why dinosaurs died out. There were also terrible fights between dinosaurs. Though there was no man to see any of the fights, the animals’ footprints could tell us that the fights did happen. What’s another reason? We can make a guess. New kinds of animals might come to the earth. Some of them had big brains and were fast and strong. They could kill dinosaurs. Some ate dinosaur eggs, too. There may be other reasons that we do not know about. Each year people will find some dinosaur footprints and bones. Scientists are trying to tell us more about dinosaurs. 1．Dinosaurs controlled the earth when ________. A．all the forests died out B．the earth became dry C．the earth was snowy D．the earth was warm and wet 2．What does the underlined word “freezing” in paragraph 2 mean? A．Wet. B．Cold. C．Warm. D．Cool. 3．How many reasons why dinosaurs died out are talked about in the passage? A．One. B．Two. C．Three. D．Four. 4．According to the passage, we are sure that________ A．not all dinosaurs had very small brains B．scientists know everything about dinosaurs C．different kinds of dinosaurs were on earth before D．new kinds of animals came to the earth and killed dinosaurs 四、短文填空 Liaoning Province is located in the northeast of China.

Known as “the great desert” in Arabic, it is about 9 million square kilometres in size, with a history of over 4.6 million years, making it one of the oldest places in the world. As the world’s largest hot desert, the Sahara is extremely dry and hot all year round. However, not all deserts are hot. For example, scientists regard Antarctica as a typical cold desert. Most of the Sahara is rocky land. Besides, it also has grasslands, lakes, mountains and sand seas, which look like endless oceans of sand. When the wind blows, the sand looks like waves. Life in the Sahara is difficult. Around 2 million people live in this area. They usually move from place to place. There is water in a few parts of the Sahara, and some people live in these places all year round. Few animals can live in a place with such a dry and hot climate. They must adapt to survive. Camels can live for a long time without water, and can drink over 100 litres of water in just 13 minutes. Fennec foxes have large ears to help their bodies stay cool. Today, the Sahara is getting even bigger. It is 10 per cent larger than it was a century ago. But why is it growing? Some scientists believe that part of the reason is climate change. As temperatures rise, summers in Africa grow hotter and less rain falls. Water bodies get smaller and the ground gets drier and drier. If we do not take effective measures, the desert will keep growing! 1．How old is the Sahara Desert according to the passage? ____________________________________________________ 2．Where can some people live all year round in the Sahara? ____________________________________________________ 3．What special ability do fennec foxes have to live in the hot desert? ____________________________________________________ 4．Why is the Sahara Desert becoming bigger and bigger these days? ____________________________________________________ 5．What can we humans do to stop the desert from growing? ____________________________________________________ 1 / 7 学科网（北京）股份有限公司 $ Unit 5 Looking into nature 课时4 Developing ideas(listening and speaking)分层作业 核心知识速记 01基础达标 02能力提升 03拓展培优 04思维进阶 词汇 boiling /ˈbɔɪlɪŋ/ adj. 很热的；滚烫的 chemical /ˈkemɪkl/ n. 化学品；化学物质 短语 be full of 充满...... as...as 和......一样...... do with 处理 be curious about 对......感到好奇 词形变化 boiling adj.很热的，滾烫的-boil v.煮沸,烧开 一、单词拼写 1．The local people use the river water for cooking because it is b________. 【答案】boiling 【详解】句意：当地人用河水做饭，因为水是沸腾的。“it is boiling”说明了使用河水的原因，前后句为因果关系，因此用形容词“boiling”来描述水的状态，表示“正在沸腾”。 2．Maybe there are some c________ in the water that give off heat. 【答案】chemicals 【详解】句意：也许水中有一些能释放热量的物质。根据“give off heat”可知，水中存在能够释放热量的东西，通常指化学物质，“chemicals”意为“化学物质”，名词，根据句中的some可知，此处要用其复数形式，故填chemicals。 二、完成句子 1．根据所给汉语提示完成英文句子，每空一词。 我对可能的原因很好奇。 I’m ________ ________ the possible reasons. 【答案】 curious about 【详解】根据中英文对照，空缺处为“对……好奇”：be curious about。 2．那是有可能的，但科学家还没有发现任何化学物质。 That’s ________, but scientists ________ ________ any yet. 【答案】 possible haven’t found 【详解】原句中“可能的”是关键词。“有可能的”对应形容词possible，构成That’s possible，意为“那是有可能的”。故①填possible。原句中“还没有发现”是关键词，是现在完成时的否定形式，yet是标志词，主语scientists（复数）对应的结构为haven’t found，其中haven’t是助动词否定形式，found是find的过去分词。故②③填haven’t，found。 3．他们的家庭充满了爱和阳光。 Their family ________ ________ ________ love and sunshine. 【答案】 is full of 【详解】句意：他们的家庭充满了爱和阳光。英语中表达“充满……”常用固定短语“be full of”。主语“Their family”为第三人称单数，be动词用“is”。故填is；full；of。 4．它几乎与黄河一样长。 That’s nearly ________ ________ ________ the Yellow River. 【答案】 as long as 【详解】原句中的关键词为“与……一样长”。“与……一样……”的固定表达为as+形容词/副词原级+as，此处“长”用形容词long，构成as long as，表示“与……一样长”。 5．我妈妈知道怎么处理旧衣服。 My mom knows what to ________ ________ the old clothes. 【答案】 do with 【详解】句意：我妈妈知道怎么处理旧衣服。原句关键词是“处理”，对应动词短语是do with，在句中与what to连用，构成“疑问词+不定式”结构，意为“怎么处理”，to后面使用动词原形，故填do；with。 一、完形填空 There is a boiling river in the Amazon rainforest.

There were many green forests. But the earth changed slowly all the time. When parts of the earth became freezing and dry, the forests there died.”可知，过去整个地球都是温暖潮湿的，有许多绿色的森林，但是现在森林死亡了，地球的气候与之前的“温暖潮湿”相反，所以是变得寒冷干燥；据此可以推断，画线单词“freezing”意为“寒冷的”，与“cold”同义。故选B。 3．细节理解题。根据第二段“Then dinosaurs could not find enough food to eat. This must be one reason why dinosaurs died out.”、第三段“There were also terrible fights between dinosaurs.”以及第四段“New kinds of animals might come to the earth.”可知，文章主要提到了恐龙灭绝的三个原因。故选C。 4．细节理解题。根据第一段“Millions of years ago, dinosaurs controlled the earth. And there were different kinds of dinosaurs on earth.”可知，数百万年前，地球上确实存在不同种类的恐龙。故选C。 四、短文填空 Liaoning Province is located in the northeast of China.

Known as “the great desert” in Arabic, it is about 9 million square kilometres in size, with a history of over 4.6 million years, making it one of the oldest places in the world. As the world’s largest hot desert, the Sahara is extremely dry and hot all year round. However, not all deserts are hot. For example, scientists regard Antarctica as a typical cold desert. Most of the Sahara is rocky land. Besides, it also has grasslands, lakes, mountains and sand seas, which look like endless oceans of sand. When the wind blows, the sand looks like waves. Life in the Sahara is difficult. Around 2 million people live in this area. They usually move from place to place. There is water in a few parts of the Sahara, and some people live in these places all year round. Few animals can live in a place with such a dry and hot climate. They must adapt to survive. Camels can live for a long time without water, and can drink over 100 litres of water in just 13 minutes. Fennec foxes have large ears to help their bodies stay cool. Today, the Sahara is getting even bigger. It is 10 per cent larger than it was a century ago. But why is it growing? Some scientists believe that part of the reason is climate change. As temperatures rise, summers in Africa grow hotter and less rain falls. Water bodies get smaller and the ground gets drier and drier. If we do not take effective measures, the desert will keep growing! 1．How old is the Sahara Desert according to the passage? ____________________________________________________ 2．Where can some people live all year round in the Sahara? ____________________________________________________ 3．What special ability do fennec foxes have to live in the hot desert? ____________________________________________________ 4．Why is the Sahara Desert becoming bigger and bigger these days? ____________________________________________________ 5．What can we humans do to stop the desert from growing? ____________________________________________________ 【答案】1．It is over 4.6 million years old. 2．They can live in the places with water in the Sahara. 3．They have large ears to help their bodies stay cool. 4．Because of climate change. (The rising temperatures, less rain, smaller water bodies and drier land make it grow.) 5．We can plant more trees, save water and take actions to slow down climate change. 【导语】本文介绍了撒哈拉沙漠的面积、气候、地貌、居民、动物以及沙漠扩张的原因。 1．第一段提到撒哈拉沙漠已有超过460万年的历史“with a history of over 4.6 million years”，答案是原文直接信息。 2．第四段提到撒哈拉沙漠有一些地方有水，有些人全年居住在那里“There is water in a few parts of the Sahara, and some people live in these places all year round”，答案是原文直接信息。 3．第五段提到耳廓狐有大耳朵来帮助身体保持凉爽“Fennec foxes have large ears to help their bodies stay cool”，答案是原文直接信息。 4．最后一段提到撒哈拉沙漠扩张的部分原因是气候变化“part of the reason is climate change”，答案是原文直接信息。 5．开放题，答案不唯一。需结合沙漠扩张的原因（如气候变化、干旱等），提出阻止沙漠扩大的措施，合理即可。 1 / 7 学科网（北京）股份有限公司 $
