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 two miles per hour, pulled out in front of a public bus going fifteen miles per hour.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.1. According to Google, what was the cause of the accident?2. How have Googles self-driving cars performed so far?Questions 3 and 4 are based on the news report you have just heard.Thousands of bees left a town after landing on the back of a car when their queen got stuck in its boot. Tom Moses, who works at a nearby national park, noticed a “brown patch” on the back of the car after the owner parked it to do some shopping. When he looked closer he realized it was a huge group of bees.Moses said: “I have never seen that many bees in one spot. It was very unusual. They were very close together and there was a lot of noise and movement. “It was interesting to see such a strange sight, but there were a lot of people around and I was a bit worried of the bees and the people stopping to look. I thought that someone might do something stupid.”Moses called two local bees specialists who helped remove the bees by attracting them into a box. Moses spent three hours looking after the bees - and was stung five times.He said: “My stings are a bit painful, but I am pleased that all worked out and I could help. People need to realize that bees are valuable and they should be looked after.3. What do we learn about Tom Moses? 4. What do we know about the bees on the back of the car? Questions 5 to 7 are based on the news report you have just heard.A new species of snake has been discovered on a remote island in the Bahamas.Scientists identified 20 of the one meter-long snakes during two trips to the Caribbean islands.

The scientist confirmed the snake was a previously unknown species after conducting a genetic analysis of tissue samples.Commenting on the find, snake expert Robert Henderson from the Milwaukee Museum of Natural History, said: “Worldwide new species of frogs are being discovered and described quite regularity.

Dont you remember all those things we used to believe when we were little? I remember my aunt Mary used to say if you swallow a cherry stone, a tree would grow out of your mouth.

But theres another one even more terrifying. That is, if you put a post stamp on upside down, you will go to prison.M: No, never heard of that. But my grandmother was a terror for that kind of thing.

We went on a campaign trip once in Italy, and my wife spent the whole time worrying about bats getting into her hair. She said her grandmother reckoned you had to shave your head to get it out.

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.16. Why does the speaker say he would like to relive the 1960s?17. What does the speaker say was the most popular thing to do at that time?18.

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 learn 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.19. What do dogs do when they are faced with angry humans?20. What does a dog do when it sees the expressions of angry dogs?21. How does a dog sense people's feelings?Questions 22 to 25 are based on the passage you have just heard.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 heartbeat 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.22. What does the speaker say about animals in winter?23. What do we learn about animals that sleep through winter?24. How do animals like mice adapt to the severe winter?25. Why do some birds fly in groups when migrating according to the speaker?2017年6月大学英语四级考试真题听力原文及参考答案（第套）Part I WritingSelling Second-hand Course BooksSecond-hand course books are being sold now.
