A recent study found that kids live longer when a grandmother takes part in their daily lives. Most animals die soon after their childbearing years are over. Women, however, often live for many years after they stop having kids. To try to understand why, researchers from Finland looked at birth and death records of two communities from the 18th and 19th centuries, one in Finland and one in Canada. In these communities, 537 Finnish women and 3,290 Canadian women were grandmothers who had lived past the age of 50. For every decade they lived beyond 50, the researchers found that the women ended up with an average of two extra grandkids. It didn't matter what the differences in health or living conditions were between the two communities or from family to family. Grandchildren were also more likely to live into adulthood if their grandmothers were alive when they were born. If their grandmothers were younger than 60 at the time, that was even better. The study also found that women had children 2 to 3 years earlier if their own mothers were still alive at that time than those whose mothers had died. The researchers suggested that grandmothers have provided important assistance in raising their grandchildren for at least the past 200,000 years. As a result, they helped extend everyone's lifespan. So, don't take your grandma for granted! Question: How did grandmothers help extend everyone's lifespan? - They provided them with better living conditions. - They provided assistance in raising their grandchildren. - They helped with housework. - They made everyone happy.
They provided assistance in raising their grandchildren.

Q: Read the following article and select the best answer. Article: Her opponent was the defending champion whose childhood dream was to win the French Open. She was the underdog who never saw the tournament on TV as a girl in China and never thought she'd get far on the red clay of the French Open, one of the four tennis Grand Slams . But it was Li Na who fell on her back in triumph on June 4. Nearly two hours' hitting gave Li a 2-0 victory over Francesca Schiavone of Italy and made her the only tennis player, man or woman, from Asia to take home a Grand Slam title. Chinese media have been swept along by the praise. An editorial carried by Xinhua News Agency said "Li Na is the best PR (Public Relations) for China," and called her an "outstanding name card for the country" and a "brilliant diplomat". It compared Li to Chinese NBA star Yao Ming, noting that both "can speak very fluent English, and both of them have a kind of sense of humor that is appreciated by foreigners". Success has come late for Li. She once gave up tennis for two years and studied journalism at Wuhan's Huazhong University of Science and Technology. But in 2004, she returned and continues to play the best tennis she could. "Dream comes true," Li said after the match. "I am so happy that my efforts have paid off." Li has often been seen as a rebel , or at least a representative of a new generation. She has a tattoo , has dyed her hair many different color1s and has even been known to yell at her husband in public. "The plain-speaking, tattooed, individualist has the ability to transcendthe sport and become a global star", the BBC news reported. No matter how important the French Open championship is, Li is not resting on her laurels -- she's already thinking about winning a second major title. "When you have the first one, naturally you will think about the second one. Now I have more confidence playing on other surfaces," Li told China Daily, as she prepares for the Wimbledon Championship, which will start on June 20. Question: Which year did Li Na begin to study journalism? - In 2004. - In 2002. - In 2006. - In 2000.
A: In 2002.

*Question*
Read the following article and select the best answer. Article: 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 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 have worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough flexibility to manage their time efficiently. Question: Why do some employers hesitate to allow remote working? - They fear losing control of their workers. - They want to stick to their routine practice. - They have little trust in modem technology. - They are used to face-to-face communication.
**Answer**
They fear losing control of their workers.
