1 . About 1.4 billion people around the world do not get enough physical exercise. The world’s adult population is about 5.6 billion, so that is tantamount to about one-fourth of the world’s adult population.

Researchers looked at 358 population-based studies between 2001 and 2016. Those studies referred to nearly 2 million people in 168 countries.

Regina Guthold was the lead author of the report. She said the study also found a wide range of physical activity levels for countries around the world. “Inactivity ranges from as low as 6 per cent in Uganda and Mozambique to 67 per cent in Kuwait. Four countries have prevalence (普遍) of inactivity of over 50 per cent. That’s Kuwait, America Samoa, Saudi Arabia and Iraq,” she said.

The report shows the levels of physical inactivity are more than two times as high in wealthy countries as they are in countries where people have low incomes. In wealthier countries, people are more likely to spend time sitting in offices. They are also more likely to use computers and electronic devices for entertainment.

There are actually many things people can do for themselves. If you work in a high-rise office building, take the stairs instead of an elevator. Go for a walk during your lunch break. Take more breaks during the workday and move around. If your workplace offers a gym or exercise classes, make sure to use them. At home, take walks with your family or friends after dinner.

Researchers have found that people who unplug their cellphones, TV, etc. over the weekend have     1     (great) satisfaction with life than people     2     spend their Saturdays stuck in their electronic equipment.

When social networking sites emerged, we     3     (believe) them to be only advantageous and not at all harmful, as they aimed to connect everyone around the world. But now we     4     (addict) to them. We have become a “connected” society     5     almost every way these days. Some people are so connected that even before brushing their teeth    6     making coffee, they will roll over to check    7     (they) phones.

    8     technology has certainly fostered (促进) more rapid and instant communication, the consequence from this has the potential     9     (be) catastrophic over the next several generations. The potential for addiction and loss of human interaction    10     (connect) with digital communication seems evident now more than ever in our current society.

6 . Many of the present generation of recent over-18s do not feel like adults, according to a survey by Nationwide Building Society, and those commenting online seem to agree. The study of 2,000 over-18s found more than one in 10 did not think of themselves as fully-fledged (成熟的) grown-ups until they reached the age of 27.

Lisa Daisy, 34, said: “Even after a career for 10 years, it still took being married to make me feel grown-up.”

But 42-year-old Carole Lutringer said she felt like an adult when she was very young. “I had to cook from an early age, because my mother worked as a headteacher,” she said. “My mother came back home late, and my father was pretty useless in the kitchen. I had to be independent from really early on, and that’s probably what made me feel grown-up earlier than most of my peers (同龄人).”

Sana Khalid Khan also had adulthood thrust upon her. She said it was the death of her father that made her grow up, at the age of 17. “Being the eldest child, a lot of responsibility fell on my shoulders,” she said.

Of those 2,000 people asked when they felt like adults, the transition (转变) happened for half in their 20s, while a fifth said it happened in their 30s. One in 20 felt they had not grown up until their 40s. Of those questioned, 55% said being an adult was dependent on major life events, for example having children, moving out of the parental home or getting married.

For others, such as Elaine Smith, in London, adulthood is only a state of mind. “I still don’t feel grown-up,” she said. “I can’t believe I am responsible for looking after a four-year-old. How did that happen? I’m 44 this year, so it may happen soon.” Commenting online, Sophie Caunter agreed. “I’m 42,” she said. “I have an 11-year-old, a seven-month-old, a husband, and I still don’t feel grown-up.” Melinda Wilmot said, “I’m 58 and still waiting to grow up.”

7 . Most children now chat daily either online or through their mobile phones.     1     Some are shy in real life but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.

Sometimes the online world, just like the real world, can cause problems, such as bullying (恃强凌弱) or arguments.     2     But there are also a few people who use the Internet for illegal aims. Children must be made aware of both the good things and the dangers.

    3     Just as you decide which TV programs are suitable, you need to do the same for the websites and the chat rooms your children visit. Remind your children that online friends are still strangers. Reminding them of the risks will keep them alert (警惕的).

    4     So it’s likely that your children may know more than you do. We get left behind when it comes to the latest gadgets and the interactive areas of websites, like chat rooms and message boards.     5     Chatters love to use abbreviations (缩略语) such as: atb (all the best), bbfn (bye bye for now), Idk (I don’t know), xlnt (excellent).

Why does one person get selected for a promotion while others with equal skills, education and experience get passed over? In my opinion, a person’s proven willingness to behave     1     (responsible) is one of the major     2     (reason). In fact, responsibility influences how the leader behaves with subordinates (下级), and it also influences the relationship with an immediate boss and with other departments in the organization. Much management    3     (guide) surprisingly overlooks this characteristic, yet it     4     (explain) many successes and failures, as well as a large portion of promotional decisions.

More than 40 years ago, Dale Miller conducted    5     examination on the promotion of his managers. Each manager received a group of 62 statements,     6     describe management behaviours, and was asked to make a forced choice, going from the most effective to the     7     (little) effective behaviour. The best managers’ choice was the statement, “Accepts full responsibility for the performance of the work unit.” This statement     8     (choose) far more frequently than statements about assignment, planning, staffing, time-management or technical skills. This choice also illustrated the sharpest distinction between the excellent managers and managers with     9     (disappoint) performance. In the end, the managers who hadn’t been promoted attached far less importance to responsible behaviours, because they were considered to be    10     (rely).

10 . Cloud computing is set to change how people communicate,work and learn.But do you know it may also affect how you are hired for a job in the future?

It was once more common for people to find jobs advertised in the newspaper and then physically send applications to organizations. Now we primarily look online using job sites and apply for those jobs using cloud recruitment (招聘) services.

However, many new technologies, with the help of artificial intelligence(AI),are changing recruitment and the way we communicate with those holding the key to our dream jobs.

AI recruitment technology, such as ENGAGE Talent, is making it easier for recruiters to find potential employees by analyzing networking sites, like LinkedIn, for appropriate candidates. Primarily based on keywords, circumstance changes or current company performance, it can find candidates that haven’t clearly expressed an interest in changing jobs. Helen Poitevin, research director of IT research firm Gartner, stated, “This method of finding a passive candidate is the subject of a lot of investment and innovation today.”

Another innovation designed to help recruiters is AI assistants, similar to Apple’s Siri. CNN reported that graduates in the future might have to be overseen by a virtual assistant before getting a real interview for highly competitive graduate programs.

Companies such as Hire Vue have already developed software that plays prerecorded questions for candidates and analyzes their responses for different factors, including grammar, facial expressions and tones. It can then produce a result that defines the candidate’s qualities and recommends whether they should be considered.

The US graduate Sarah Ali has been through eight Hire Vue interviews. She told CNN, “Once I understood the AI interview process, I started thinking of it as a game and how I could optimize (优化) myself.”

This interview process has yet become the mainstream outside the US, but with the power of cloud computing, how long will it be before this tech is used worldwide?
