阅读理解What will the weather be like tomorrow? Some people say they can forecast(预测)the weather from animals.Some of them look at seabirds. When they see seabirds fly high, they say it will be a nice day. When the weather is bad, the seabirds stay on the shore(岸). They don't like to fly in strong winds and they sit in trees when rain is on the way.Other people look at different animals on the farm. For example, chickens may make a lot of noise and run here and there when rain is on the way. Frogs(青蛙)can tell the weather, too. When rain is on the way, they stay in water and make a lot of noise too. But when it is a nice day, they will be quiet and jump out of the water.(1)When some people see seabirds ________ they think it is going to be a nice day.A.sit in trees B.stay on the shore C.fly high D.fly to the trees(2)Chickens ________ when rain is on the way.A.run around B.keep quiet C.know nothing D.sit in trees(3)When rain is on the way, frogs may ________.A.eat a lot B.not make a lot of noise C.go to the land D.not jump out of the waterWe talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we will let others know soon. But do you know that a tree can talk and share news? It sounds strange, but it's true that some trees can also communicate with each other. Of course, no tree moves lips and says words just as people do.Willow trees(柳树)are the best- known of these trees. When insects(昆虫)begin eating a willow tree, the tree gives out a special smell at once. This smell tells the other willow trees that insects are coming near. All of them quickly make a chemical(化学物质)in their leaves. This chemical is bad for the insects. The insects do not like it and they fly away soon. In this way, the willow trees keep themselves away from the insects.Next time when you take a walk near the trees, maybe the trees are "talking" to each other quietly. And when someone says that trees cannot "talk", please tell them that even trees can "talk" to each other, too.(1)Willow trees communicate with each other by ________.A.words B.winds C.smells D.sounds(2)The underlined word "lips" in the first paragraph means ________.A.树干 B.嘴唇 C.枝条 D.手势(3)________ make(s) the insects fly away.A.The leaves on the willow treesB.The"talk"between the willow treesC.The special smell that willow trees give outD.The chemical that willow trees make in their leaves(4)The passage tells us that some of the trees can ________.A.speak just as people doB.tell stories to municate with each otherD.kill insects in the woodsFamily traditions are special habits or customs that your family have. For example, in the family of Bill Gates, his parents keep the tradition of reading with children. And what's the tradition in your family?★ Nick, 15, EnglandOn every family member's birthday, we give him or her a surprise. Last Sunday, it was my mother's birthday. And I knew that she wanted to see a film. So I bought a ticket without telling her first. This made her really happy.★ Jack, 15, CubaEvery weekend, my parents and I go to my grandparents' home. My grandparents cook many delicious foods. I meet all my cousins. We talk about interesting things at school. Sometimes, my parents also join us to play games.★ Yu Xin, 14, ChinaDuring every summer or winter holiday, we have a family trip across the country. I'm always the one who chooses where to go.

When you are near a lake or an ocean, you feel cool. Why? The sun makes the earth(地面)hot but it cannot make the water very hot. Although the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth goes up. Then the cool air over the water moves in and takes the place of the hot air. When it moves in, you will feel the wind. And the wind makes you cool.Of course, scientists cannot answer all of our questions. If we ask "Why is the ocean full of salt(盐)?", scientists will say that the salt comes from rocks.When a rock gets very hot or very cold, it cracks(断裂). Rain falls into the cracks and then carries the salt into the ocean. But then we ask, "What happens to the salt in the ocean?" The ocean does not get saltier every year. Scientists are not sure about the answer to this question.We know a lot about our world. But there are still many answers which we don't have and are curious(好奇的)about.(1)The main idea of this passage is that ________.A.people feel cool when they are near a lake or an oceanB.scientists can explain many things, but not everythingC.scientists can explain everything about the oceanD.the salt in the ocean comes from rocks(2)Now scientists know ________.A.what makes people feel cool near a lake or an ocean in summerB.everything about the oceanC.what happens to the salt in the oceanD.why the ocean does not get more and more salty(3)A rock cracks when ________.A.rain falls B.it gets very hot C.it gets very cold D.both B and C(4)In the first paragraph, the underlined word "it" refers to ________.A.the hot air over the waterB.the cool air over the earthC.the hot air over the earthD.the cool air over the water(5)Which of the following is NOT mentioned in this passage?A.The reason why people feel cool when they are near a lake or an ocean in hot weather.B.The reason why the ocean doesn't get saltier every year.C.The reason why the water in the ocean is salty.D.The reason why rocks crack.阅读短文,完成下列小题。Peter always doesn't know the way.

In fact, I'd like to relive a period I've already lived – the 1960s.I was in my twenties, and everything was being renewed. People would come in out of a formal and almost Victorian attitude, and you really felt anything was possible. Meeting people was the thing, and you went to coffee bars where you met friends and spent the evening. The cinema, the theater, all that was every exciting with new things coming out. In fact, we seemed to be out, all the time! I don't really remember working – of course, I was a student – or sitting around at home very much. That just wasn't where the scene was, even eating! It was the first time, ordinary people started going out to eat. We were beginning to be adventurous about food, but we were more interested in meeting people than in eating or drinking. And dress, yes, that was the revolution. I mean, girls went around in really short skirts, and wore flowers in their hair. And men were in jeans, and could wear their hair long too. It was a wonderful period. It was like living in an age you could never have imagined, and that never has come back. We didn't have much money, but it didn't matter. And there was plenty of opportunity to do whatever you felt like doing.Q16. Why does the speaker say he would like to relive the 1960s?C)Everything seemed to be changing.Q17. What does the speaker say was the most popular thing to do at that time?A)Meeting people.Q18. What do we learn about the speaker?D)He was a young student in the 1960s.[Passage 2]Dogs, man's best friends, have a clear strategy for dealing with angry owners—they look away.New research shows that dogs limit their eye contact with angry humans. The scientists suggest this may be an attempt to calm humans down. This behavior may have evolved as dogs gradually learned they could benefit from avoiding conflicts with humans.To conduct the tests, the University of Helsinki researchers trained 31 dogs to rest in front of a video screen. Facial photos of dogs and humans were displayed on the screen for 1.5 seconds. They showed threatening, pleasant and neutral expressions. Nearby cameras tracked the dogs' eye movements.Dogs in the study looked most at the eyes of humans and other dogs to sense their emotions. When dogs looked at expressions of angry dogs, their eyes rested more on the mouth, perhaps to interpret the threatening expressions. And when looking at angry humans, they tended to turn away their gaze.Dogs may have learned to detect threat signs from humans and respond by trying to make peace, according to researcher Sanni Somppi. Avoiding conflicts may have helped dogs develop better bonds with humans.The researchers also note that dogs scan faces as a whole to sense how people are feeling, instead of focusing on a given feature. They suggest this indicates that dogs aren't sensing emotions from a single feature, but piecing together information from all facial features just as humans do.Q19. What do dogs do when they are faced with angry humans?B)They avoid looking at them.Q20. What does a dog do when it sees the expressions of angry dogs?C)It focuses its eyes on their mouths.Q21. How does a dog sense people's feelings?B)By taking in their facial expressions as a whole.[Passage 3]Winter in many places is very cold. There is lots of snow around, and the ground freezes, which can make life difficult for animals. People in cold places live in warm houses and have learned to adapt. What do animals do? There are three main ways that animals survive the cold in winter: sleep, adapt or migrate.Some animals, such as bears, frogs and snakes, sleep all winter. They sleep very deeply and need little or no food. While sleeping, their body temperature drops, and their heart beat slows down. To prepare for this before winter, these animals eat extra food to become fat, which gives them the energy they need while they sleep.Other animals adapt. For example, by staying active in winter. It is often hard for them to find food. So some animals, such as mice, collect extra food before winter, and hide it. When winter comes, they return to their hiding places to eat the food. Some animals grow thicker fur, or live in tree holes or underground to stay warm.Some birds migrate by flying to a warmer place for the winter, where they can find more food. Some fly very long distances, including one kind of bird that flies from the remote north of the world, all the way to the distant south. Some birds fly in groups for safety, while others fly alone.Q22. What does the speaker say about animals in winter?D)They resort to different means to survive the bitter cold.Q23. What do we learn about animals that sleep through winter?C)They consume the energy stored before the long sleep.Q24. How do animals like mice adapt to the severe winter?A)By storing enough food beforehandQ25. Why do some birds fly in groups when migrating, according to the speaker?C)To stay safe2017年6月大学英语四级考试真题(一)听力原文[News Report 1]One of Google's self-driving cars crashed into a bus in California last month. There were no injuries.It is not the first time one of Google's famed self-driving cars has been involved in a crash, but it may be the first time it has caused one.On February 14th the self-driving car, travelling at 2mph (3km/h), pulled out in front of a public bus going 15mph (24km/h).The man in the Google vehicle reported that he assumed the bus would slow down to let the car out, and so he did not switch to the manual mode.In a statement, Google said: "We clearly bear some responsibility, because if our car hadn't moved, there wouldn't have been a crash."That said, our test driver believed the bus was going to slow or stop to allow us to merge into the traffic, and that there would be sufficient space to do that."The company's self-driving cars have done well over a million miles across various states in the US, and until now have only reported minor accidents.Q1: According to Google, what was the cause of the accident?B)The test driver made a wrong judgement
