【题目】阅读理解

阅读下列短文,从每题所给的四个选项 (A 、B 、C D )中,选出最佳选项。

Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name —phubbers(低头族).

Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

Although the ending sounds overstated, the damage phubbing can bring is real.

Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying, “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

But that’s not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Beijing Evening News reported.

It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

1】For what purpose does the author give the example of a cartoon in Para. 2?

A. To advertise the cartoon made by students.

B. To inform people of the bad effects of phubbing.

C. To indicate the world will finally be destroyed by phubbers.

D. To warn doctors against using cell phones while treating patients.

【2Which of the following is NOT a risk a phubber may have?

A. His social skills could be affected.

B. His neck and eyesight will be gradually harmed.

C. He might get separated from his friends and family.

D. He will cause the destruction of the world.

【3Which of the following may be the author’s attitude towards phubbing?

A. Supportive. B. Optimistic.

C. Opposed. D. Objective.

【4What may the passage talk about next?

A. Measures to reduce the risks of phubbing.

B. People addicted to phubbing.

C. Definition of phubbing

D. Consequences of phubbing.

【题目】阅读理解

阅读下列短文,从每题所给的四个选项 (A 、B 、C D )中,选出最佳选项。

Digital technology - email and smart phones especially-have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey of office workers conducted by Wakefield Research for the IT company Citrix, most bosses are doubtful about remote working. Half of the workers say their boss doesn't accept it, and only 35 percent say it's tolerated.

Skeptical bosses will likely have their doubts reinforced (加深) by the same survey, which shows that 43 percent of workers say they've watched TV or a movie while “working” remotely, while 35 percent have done housework,and 28 percent have cooked dinner.

It is true, however, that working at home makes people much more efficient, because it allows workers to take care of annoying housework while still getting their jobs done. It’s much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush.

The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker.

More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who haven't worked remotely would rather give up some bonus in order to get even one day a wee working from home. Under such circumstances, smart firms need to find ways to let their employees have enough ability to change or be changed easily to suit a different situation to manage their time efficiently.

1】Why do some employers hesitate to allow remote working?

A. They are used to face-to-face communication.

B. They want to stick to their routine practice.

C. They have little trust in modem technology.

D. They fear losing control of their workers.

【2What seems to be most workers' attitude toward remote working?

A. Favorable. B. Doubtful.

C. Reserved. D. Disapproving.

【3What does the author suggest smart firms do?

A. Shorten their office hours.

B. Give employees a pay raise.

C. Adopt flexible work patterns.

D. Reduce their staff’s workload.
