Part 3 Reading and Writing (第三部分读写)

VI. Reading comprehension (阅读理解)(共50分)

A. Choose the best answer(根据短文内容,选择最恰当的答案)(12分)

When taking an elevator, do you often push the “close” button You hope by pushing it, the elevator door will close faster. But what if the button is actually fake(假的)

Karen Penafiel is the executive director(执行董事)of the US National Elevator Industry. She said that elevators’ “close” buttons are a complete trick, at least in the US, and that doors will not close any faster no matter how hard you push.

In the 1990s the Americans with Disabilities Act(《美国残疾人法案》)was passed in the US. It means all elevators have to stay open long enough to allow disabled(残疾的)people to enter. Only US firefighters and elevator workers can really use the buttons with special keys.

But the buttons aren’t completely useless. According to psychologists(心理学家), fake buttons can make you feel better. They give you a sense of control that can help reduce stress. That’s why some other buttons in our lives are fake, too.

For example, many offices in the US have fake thermostats(温控器). People may feel better when they think they can control the temperature in their workspace.

You were told that traffic light buttons could help make the traffic signals change faster. But they may not really work either.

However, even when people know these little “white lies”, they still push fake buttons. As long as the doors finally close, it seems worthy.

John Kounios is a psychology professor at Drexel University in the US. He told The New York Times that he always pushes the traffic light buttons. “After all, I’ve got nothing else to do while waiting. So why not push the button on the off chance that this one will work”

69.If you push the “close” button in the US, the elevator door will ________.

A. close immediately

B. not be completely open

C. play a trick on you

D. not close as fast as you wish

70.In the US, in order for disabled people to go in safely, ________.

A. elevator workers will press the “open” button for them

B. they will be given a special key to use in the elevators

C. all elevators are designed to open long enough

D. no “close” button is fixed on the elevators

71.Which of the following is NOT mentioned as fake

A. Thermostat buttons.

B. Elevator buttons.

C. Traffic light buttons.

D. Power buttons.

72.There are quite a few fake buttons in our lives because they can ________.

A. control people’s senses

B. help people feel better

C. control the temperature

D. tell “white lies”

73.The underlined words “on the off chance” in the last paragraph most probably mean

“______”.

A. with the little hope

B. without any plan

C. with a great opportunity

D. without any possibility

74.The best title for the passage is ________.

A. Button pushing society

B. Useless buttons

C. Buttons for disabled people

D. Fake elevator buttons

B. Choose the best words and complete the passage(选择最恰当的单词完成短文)(12分)

Is it stressful and boring working at Google, one of the largest technology companies in the world Not at all! __75__, Google has the best working environment among the big companies in the United States.

The working environment is quite __76__ at Google. The company encourages staff to do whatever they want in the office. They can design their own desks or work stations. They

can write down their ideas on the wall. When they are tired, they can take a nap(打盹)on the sofa. Animal lovers can __77__ bring their pets to work.

Google is home to every employee. In addition to offices, there are game rooms, hair salons, restaurants and gyms. After work, employees can have a swim in the swimming pool

or enjoy a massage(按摩). The company also encourages them to learn new things. It __78__ a number of interesting free courses such as sign language, cooking, drawing and playing the piano.

There is an interesting rule at Google—no staff member should be 100 feet away from food. Coffee bars and open kitchens are __79__. All food is free. There are thousands of different dishes in the main restaurant. One of its managers says, “We care for our employees’ __80__, so we encourage them to have healthy food. Our research shows that if people are provided with enough food, they make better choices.”

To work hard and work well, you need to love what you are working on and where you

are working. Google believes that an interesting and pleasant space helps people think more creatively. So it is trying hard to keep its title as the happiest workplace in the world.

75.A. After all B. By the way C. For example D. In fact

76.A. surprising B. relaxing C. interesting D. amusing

77.A. almost B. ever C. even D. both

78.A. guides B. offers C. takes D. learns

79.A. everywhere B. somewhere C. anywhere D. nowhere

80.A. choice B. cooking C. health D. behavior

C. Read the passage and fill in the blanks with proper words(在短文的空格内填入适当的词,使其内容通顺。每空格限填一词,首字母已给)(14分)

I remember a psychiatrist(精神病医生)once said that if you ever feel sad, the best thing to do is do something for someone else because it gets you focused. It’s hard to be unhappy while serving someone else. A byproduct(副产品)of h__81__ others is feeling wonderful yourself.

I remember sitting in an airport one day, waiting for my flight. I was e__82__ because I had been upgraded(升级)to a first-class ticket. I had the best seat on the plane, seat 1A.

B__83__ boarding, I noticed a young lady who had several carry-on bags and was holding a crying baby. Having just finished reading a book on doing acts of kindness, I heard my conscience(良心)speak to me, “You guy, let her h__84__ your ticket.” I fought these words for a while but finally gave in.

“Excuse me, but it seems that you could use this first-class ticket more than me. I know how hard it can be flying with a k__85__. Why don’t we trade(交换)our tickets.”

“Are you sure”

“Oh yeah. I really don’t mind. I’m just going to be working the whole time, anyway.”

“Well, thank you. That’s very kind of you,” she said as we e__86__ our tickets.

As we boarded the plane, I was surprised at how good it made me feel to watch her sit down in seat 1A. In fact, at that time, seat 24B or wherever I was sitting didn’t seem that bad at all. During the flight I was so curious to see how she was doing that I could h__87__ stand (忍受)it. So I got up out of my seat, walked to the first-class section. There she was with her baby, both in big and comfortable seat 1A. And I felt like getting a million dollars. I’ve got to keep doing this kind of thing.

D. Answer the questions(根据短文内容回答下列问题)(12分)

Two close friends were Willie Brown and his little dog Bounce. Willie could never think of taking a walk without Bounce. Cake and play were equally shared between them. Willie taught his dog many tricks, and often said that Bounce could do almost anything in the world but talk.

There came a time, however, when Bounce really told Willie’s father something, though he could not talk.

It was a bright summer afternoon. Willie had walked with Bounce down to the river, which was not more than two blocks from his father’s store. Willie began to throw stones into the water, and Bounce lay on the grass, watching the flies(苍蝇)and catching any that came too near. There were some logs(圆木)in the river near the bank. Willie jumped upon one of them, to see if he could throw a stone across the river. Just as it left his hand, the log turned, and he fell into the water. He did not know how to swim, and there was no one to hear, though he called as loud as he could for help.

Poor little Bounce gave a great barking of worry. He ran up and down the bank two or three times, barking, looking first at Willie and then around. Then he started to run as fast as he could, up the street to the store.

When he got there the door was shut, but he scratched(挠) against it and barked loudly, until someone came and opened it.

He caught hold of Mr. Brown’s clothes then ran to the door, then back again, catching at him, barking, and jumping. Now, Mr. Brown thought, “Something must be wrong.” Immediately he followed Bounce to the riverside.

Willie was saved in time.

88.Bounce was Willie’s close friend, wasn’t he

89.How far was the river away from Willie’s father’s store

90.Why did Willie jump on one of the logs in the river

91.How did Bounce feel when he found Willie in the river

92.Who do you think saved Willie’s life

93.How do you like Bounce Why

My husband Jack changed his job and had to move to another city to work. We decided to put our old house for sale. Three weeks later, it was still on the market. I became a busy housekeeper. Every room had to be kept tidy, and dishes had to be washed and put away after each meal. Then one day the doorbell rang unexpectedly at 8 am. Sleepily, I opened the door and saw our agent standing there with a couple. “There was no time to call”, he explained, “Because the couple had to catch a plane home in New York.”

The three people made their way, passed the dirty breakfast dishes on the kitchen table and into the bedroom with unmade beds. As I walked quietly into a bathroom to brush my hair, I heard the man say something to his wife. Then they both laughed.

Two days later, the agent phoned to tell me that the couple decided to buy the house. He repeated what the buyer had said when he gave me the check the following day: “That house has a warm feeling, just like ours.”

D.Listen to the passage and complete the following sentences (听短文,完成下列内容。每空格限填一词) (10分)

We are told breakfast is the most important meal of the day, and dinner the most enjoyable. But what about lunch Nowadays, not many people take time to enjoy this midday meal. We just take a quick salad, or buy a sandwich and eat at our computers. Sometimes, when there is an emergency, we just give up lunch. The development of technology hasn’t

done our eating habits much good. Our attention is often attracted by e-mails, social media, 24-hour news, and so on.

Long working hours can cause different kinds of health problems. Bosses should encourage workers to take time off for lunch. This is because long lunch breaks can do good to people. To take a lunch break is to slow down and gain some views. A break from work allows people to think outside the box.

What we eat at lunch is also important. A fast-food lunch is more harmful than not having lunch at all. And it’s not just about unhealthy food. Recent studies show that fast food is also harmful to how we think. However, if we sit down at a proper restaurant and chat with others, we are more likely to slow down what we are doing, which can hardly be achieved in a noisy and crowded fast-food chain.
