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, traveling at 2 mph, pulled out in front of a public bus going 15 mph. [1]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 dearly bear some responsibility, because if our car hadn’t moved, there wouldn’t have been a crash. [1] 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.” [2] 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.

[3] 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’ve never seen that many bees in one spot. It was very unusual. [4] 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 about the bees and the people stopping to look. I thought that someone might do something stupid.” Moses called two local bee 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 Tm pleased it all worked out and I could help. People need to realize that bees are valuable and they should be looked after.”

[5] 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. [6] One of the creatures made a dramatic appearance by moving onto the head of the team leader as he slept. [7] The snake has been named Silver Boa because it is metal-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 Milwaukee Museum of Natural History, said, “Worldwide, new species of frogs are being discovered and described quite regularly. New species of snakes, however, are much rarer.”

M: [12] 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 is only a little boy. Don’t you remember all those things we used to believe when we were little? [13] I remember my aunt Mary used to say if you swallow a cherry stone, a tree will 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. [14] The one that used to get me was that swans could break your leg with a blow of the wing.
M: They can, can’t they? I always thought they could.
W: No, they are not that strong. But there is another one even more terrifying. That is if you put a postage stamp on upside down, you’ll 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’ll get a spot on your tongue if you tell a lie. If you eat stale bread, your hair will curl. And here is one more. [15] We went on a camping trip once in Italy and my wife spent the whole time worrying about bats getting into her hair.

If I could go back in history and live when I liked, I wouldn’t go back very far. [16] 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 were coming out of a formal and almost Victorian attitude, and you really felt anything was possible. [17] 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 very exciting with new things coming out. In fact, we seemed to be out all the time. [18] 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 [17] 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.

19. A 录音开头说到“Dogs, man’s best friends, have a clear strategy for dealing with angry owners—they look away.”如果主人生气，狗会把目光移开。研究也表明，狗会避免与生气的人类的眼神交流。
20. D 录音中提到“When dogs looked at the expressions of angry dogs, their eyes rested more on the mouth.”说明实验对象（狗）看到狗生气的表情时，它们就看着对方的嘴巴。
21. C 录音末尾提到，研究者们说狗通过整体地看人脸来判断人的情绪，而不是只聚焦在人脸部的某一器官上。【录音原文】
[19] 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. [20] When dogs looked at the 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. [21] The researchers also note that dogs scan faces as a whole to sense how people arc feelings 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.
Questions 19 to 21 are based on the passage you have just heard.
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?

22. C 录音中提到“There are three main ways that animals survive the cold in winter: sleep, adapt or migrate.”也就是说动物以三种方法度过寒冷的冬天：冬眠、适应与迁徙。后面便详细地说明了这三种方法。
23. B 录音中提到在冬天来临之前，冬眠的动物会吃额外的食物来变胖，这样可以在它们冬眠的时候给予它们能量。由此可知，冬眠的动物在冬眠时消耗的是冬眠前储存的能量。
24. D 录音中提到老鼠这样以适应环境的动物在冬天之前会收集额外的食物并把食物藏起来，冬天到来后，它们再去藏食物的地方去吃这些食物。所以老鼠是提前在冬天到来之前储存好食物。
25. A 录音结尾提到，为了安全一些鸟儿成群迁徙。【录音原文】
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? [22] 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. [23] 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. [24] It is often hard for them to find food, so some animals such as mice collect extra food to before winter and hide it. When winter comes, they return to the 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. [25] Some birds fly in groups for safety, while others fly alone.
Questions 22 to 25 are based on the passage you have just heard.
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?
