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

Television has opened windows in everybody’s life.Young men will never again go to war as they did in 1914,Millions of people now have seen the effects of a battle.And the result has been a general dislike of war,and perhaps more interest in helping those who suffer from all the terrible things that have been shown on the screen. Television has also changed politics.The most distant areas can now follow state affairs,see and hear the politicians before an election.Better informed,people are more likely to vote,and so to make their opinion count. Unfortunately,television’s influence has been extremely harmful to the young.(76)Children do not have enough experience to realize that TV shows present an unreal world; that TV advertisements lie to sell products that are sometimes bad or useless.They believe that the violence they see is normal and acceptable.All educators agree that the “television generations” are more violent than their parents and grandparents. Also,the young are less patient. Used to TV shows,where everything is quick and interesting,they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn’t do funny things like the people on children’s programs.And they expect all problems to be solved happily in ten,fifteen,or thirty minutes.That’s the time it takes on the screen.1.In the past,many young people ______.A.knew the effects of warB.went in for politicsC.liked to save the wounded in warsD.were willing to be soldiers2.Now with TV people can _____.A.discus politics at an information centerB.show more interest in politicsC.make their own decisions on political affairsD.express their opinions freely3.The author thinks that TV advertisements _____.A.are not reliable on the wholeB.are useless to peopleC.are a good guide to adultsD.are very harmful to the young4.Which is NOT true according to the passage?A.People have become used to crimes now.B.With a TV set some problems can be solved quickly.C.People now like to read books with picture.D.The adults are less violent than the young.5.From the passage,we can conclude that _____.A.children should keep away from TVB.TV programs should be improvedC.children’s books should have picturesD.TV has a deep influence on the young
