高三英语单项填空中等难度题查看答案及解析

Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the “on/off” button on the TV. But some buttons are actually fake, like the “close” button on a lift.

Many people are in the habit of pressing the “close” button because they don’t have the patience to wait for the lift doors to shut. But lifts’ “close” buttons are a complete scam (骗局), at least in the US － the doors will not close any faster no matter how hard you press.

It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

But to normal lift riders, the buttons aren’t completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

“Perceived (能够感知的) control is very important. It reduces stress and increases well-being,” Ellen J. Langer, a psychology professor, said, “ having a lack of control is associated with depression.”

Experts have revealed that a lot of buttons that don’t do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workspace.

But psychologists found it interesting that even when people are aware of these little “white lies”, they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

“That habit is here to stay,” John Kounios, a psychology professor, said. “Even though I have real doubts about the traffic light buttons, I always press them. After all, I’ve got nothing else to do while waiting. So why not press the button in the hope that this one will work?”

1.　 What was the author’s main purpose in writing the article?

A. To analyze the functions of fake buttons.

B. To describe some different kinds of fake buttons.

C. To explain the advantages and disadvantages of fake buttons.

D. To explore people’s different habits when it comes to pushing buttons.

2.　 In America, the “close” buttons on lifts _______.

A. are fake for the convenience of disabled people

B. work only when people press them hard for a while

C. were specially designed to give people a sense of control

D. cannot speed up the process of closing the door in any case

3.　 The underlined part “for this same purpose” in Paragraph 6 refers to _______.

A. making people more patient

B. giving people perceived control

C. helping people to build up confidence

D. making people with depression feel better

4.According to John Kounios, people who press fake buttons ______.

A. should give up this habit

B. probably do so to kill time

C. consider what they do to be meaningless

D. don’t know that what they press is fake

Have you ever pressed the pedestrian button at a crosswalk and wondered if it really worked?　 They’re called “placebo(安慰剂）buttons”一buttons that mechanically sound and can be pushed，but provide no functionality.

In New York City, only about 100 of the 1, 000 crosswalk buttons actually function. Crosswalk signals were generally installed before traffic jam had reached today’s levels.

But while their function was taken over by more advanced systems—such as automated lights or traffic sensors — the physical buttons were often kept, rather than being replaced at further expense. Other cities，such as Boston，Dallas and Seattle，have gone through a similar process, leaving them with their own placebo pedestrian buttons. In London, which has 6, 000 traffic signals，pressing the pedestrian button results in a reliable “Wait” light. But that doesn’t necessarily mean that the “green man”— or “pedestrian stage” in traffic signal design profession — will appear any sooner.

“We do have some crossings where the green light comes on automatically, but we still ask people to press the button because that enables accessible features,’’ said Glynn Barton, director of network management at Transport for London.

These features, such as blind tracks and hearable traffic signals, help people with visual disorder cross the road and only function when the button is pressed. As for the lights, a growing number of them are now combined and become a part of an electronic system that detects traffic and adjusts time frequency accordingly (giving priority to buses if they’re running late, for example), which means that pressing the button has no effect.

According to Langer, a Harvard psychologist, placebo buttons give us the illusion (错觉)of control — and something to do in situations where the alternative would be doing nothing. In the case of pedestrian crossings, they may even make us safer by forcing us to pay attention to our surroundings. “They serve a psychological purpose at the very least,” she added.

1.Why are the physical buttons still kept in some cities?

A. Because it may cost money to replace them.

B. Because they remain as memories of a city.

C. Because do have real functions in traffic.

D. Because they can result in reliable lights.

2.Which of the following word can replace the underline word “features” in Paragraph 4?

A. Functions.

B. Uses.

C. Equipment.

D. Facilities.

3.If you pressed a “placebo button” in London, what would happen?

A. All traffic would be affected.

B. Some kind of sound might appear.

C. Pedestrians came first to cross the road.

D. “Green man” were bound to show up earlier.

4.What can we know about “palcebo buttons” from Langer’s words?

A. They can really control traffic.

B. They serve little functions.

C. They may work mentally.

D. They can help the blind.

Have you ever experienced such an annoying thing as it took so long to open a web page? You're watching stops every few minutes, which ruined your internet experience. But it could be a thing of the past. On June 3, the Ministry of Industry and Information Technology announced that China would issue licenses for the commercialization of 5G. It means major telecom carriers will start to provide 5G services.

The "G" in "5G" refers to the generation of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the internet, and 4G made all of these things faster.

Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chant with your friend, there is generally a 100 to 200 milliseconds (毫秒) delay with 4G, but 5G will reduce the delay to 1 millisecond or less, which is almost real time.

With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid potential dangers. Meanwhile, 5G enabled wearable devices will keep doctors constantly updated on the health status of their patients and warn them immediately if there’s something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not "travel" far. On 4 networks, you can be 10 kilometers away from the nearest transmission (传输) base and barely lose signal. But 5G will only cover about 300 meters, meaning we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new specially, designed for 5G that are currently expensive.

1.What is the function of the first paragraph?

A.To provide a background of the topic.

B.Tu offer basic knowledge of the topic.

C.To use an example to support the topic.

D.To draw readers’ attention to the topic.

2.According to the passage, what is likely to happen to our life with 5G?

A.Doctors can treat more patients.

B.No drivers are needed in the near future.

C.Many advanced technologies will be further improved.

D.Children will hate playing VR games in the real world.

3.What can he found when 5G is compared with 4G?

A.4G cover smaller areas. B.4G needs more transmitters.

C.5G signals can travel farther. D.5G costs higher in early stage.

4.What is the text mainly about?

A.The development of 5G.

B.Challenges that 5G will face.

C.Benefits that people will get from 5G.

D.The difference that 5G will make to our lives.
