求学资讯网更新了“2017年6月英语四级考试听力真题原文卷一 ”，供考生参考，希望能帮助到你们。
　　一.新闻听力　　【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　　Q2: How have Google’s self-driving cars performed so far?　　D They have generally done quite well.　　【News Report 2】　　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
movements, it was interesting to see such a strange sight. But there were a lot
of people around and I was a bit worried about the bees and the people stopping
to look. I thought that someone might do something stupid.　　Moses called two local bees specialists who helped removed 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.　　Q3. What do we learn about Tom Moses?　　A He works at a national park.　　Q4. What do we know about the bees on the back of the car?　　B They were making a lot of noise.　　【News report 3】　　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 second trip was made in October last year.　　One of the creatures made a dramatic appearance by moving on to the head of
the team leader as he slept.　　The snake has been named silver boa because it is metallic colored and the
first specimen found was climbing a silver palm tree.　　The team was led by Dr. Graham Reynolds, from Harvard University, 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 Museum of
Natural History, said: “Worldwide new species of frogs are being discovered and
described quite regularity. New species of snakes, however, are much rarer.　　Q5. What is the news report mainly about?　　A The discovery of a new species of snake.　　Q6. What do we learn about the scientific team leader?　　C A snake crawled onto his head in his sleep.　　Q7. How did the newly discovered creature get its name?　　D From its colour.　　二.对话听力　　【Conversation 1】　　W: Did you enjoy your stay with us, Mr. Brown?　　M: Yes, very much. I had a wonderful time here. Now I'm going to the
airport. My flight leaves in less than 2 hours. So, could you tell me, what's
the quickest way to get there?　　W: Well, we can call a taxi for you. We also have a free airport shuttle
service.　　M: That sounds great, but will the shuttle get me to the airport in
time?　　W: Yes, it should. The next shuttle leaves in 15 minutes. And it takes some
25 minutes to get to the airport.　　M: Fantastic! I'll just wait in the lobby. Will you please let me know when
it's leaving?　　W: Of course, sir.　　M: Now I would like to settle my mini-bar bill. How much is that?　　W: Let's see. It comes to $37.50. How would you like to pay for it?　　M: I'll pay with my credit card. Thanks. But I'll need a receipt, so I can
charge it to my company.　　W: Absolutely! Here you are, sir. If you like, I can leave your bags with
the porter. And he can load them onto the shuttle for you when it arrives.　　M: That would be great. Thank you.　　W: Would you like to leave a comment on our web page when you have
time?　　M: Sure. I had a really good stay here, and I'd like to recommend your
hotel to my friends and colleagues.　　W: That’s very kind of you. Thank you again for staying at Sheraton
Hotel.　　Q8. Why does the man ask about the quickest way to the airport?　　A The security check takes time.　　Q9. How is the man going to pay his bill?　　B By credit card.　　Q10. What did the man ask the woman to do?　　A Give him a receipt.　　Q11. What favor does the woman ask of the man?　　D Posting a comment on the hotel’s webpage.　　【Conversation 2 】　　M: You know, Ben’s given up making those terrible faces he used to make.
The other day, he came home from school almost in tears. His teacher said if he
went on like that, his face would get stuck when the winds changed.　　W: And he believed her?　　M: Yeah, he’s only a little boy. Don’t 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 cherrystone, a tree would grow out of your mouth. And I’m still
terrified today, sort of subconsciously. You know, if I swallow one by
mistake…　　W: Yeah, I suppose you're right. The one that used to get me was that swans
could break your leg when they blow of the wing.　　M: They can, can’t they? I always thought they could.　　W: No, they are not that strong. But there’s 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. For example, she would say, you will get a spot on your tongue if you
tell a lie. If you eat stale bread, your hair will curl. And here’s one more. 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. My wife was really terrified.　　W: Silly, isn’t it? But that’s how some parents try to keep their kids from
doing the wrong thing or getting into trouble.　　Q12: What does the man say about Ben?　　C He has stopped making terrible faces.　　Q13: What did aunt Marry used to do when the man was a child?　　D Warn him of danger by making up a story.　　Q14: What does the woman believe swans could do?　　They could break pp’s legs.　　Q15: What did the grandmother of the man’s wife say?　　B One would have to shave their head to remove a bat in their hair.　　三.短文听力　　【Passage 1】　　If I could go back in history and live when I liked, I wouldn't go back
very far. 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.　　Question 16 – 18 are based on the passage you have just heard:　　16. Why does the speaker say he would like to relive the 1960s?　　C Everything seemed to be changing.　　17. What does the speaker say was the most popular thing to do at that
time?　　A Meeting people.　　18. 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.　　Questions 22-25 are based on the passage you have just heard.　　22. What does the speaker say about animals in winter?　　D They resort to different means to survive the bitter cold.　　23. What do we learn about animals that sleep through winter?　　C They consume the energy stored before the long sleep.　　24. How do animals like mice adapt to the severe winter?　　A By stori　　一.新闻听力　　【News Report 1】　　One of Google's self-driving cars crashed into a bus in California last
