Read the following article and select the best answer. Article: Contrary to common belief, social media websites such as Facebook do not weaken personal ties, they strengthen them in unique ways for different age groups, according to a new study. The rapid spread of Facebook, which has more than 500 million users worldwide, has prompted concerns about its negative effects, but researchers at the University of Texas have reached a different conclusion. "Our findings suggest that Facebook is not replacing face-to-face interactions between friends, family and colleagues," said S.Craig Watkins, an associate professor of radio, TV and film who headed the research team. "In fact, we believe there is sufficient evidence that social media afford opportunities for new expressions of friendship, intimacy and community." The researchers questioned 900 college students and recent graduates about how and with whom they interact on Facebook. More than 60 percent of Facebook users said posting status updates was among the most popular activities, followed by 60 percent who wrote comments on their profile and 49 percent who posted messages and comments to friends. The researchers also found that although about the same number of men and women use Facebook, they do so in different ways. "There is a noteworthy difference in aims in how to use a tool like Facebook.We found that for women the content tends to be more affectionate, and (they) are especially interested in using it for connection," said Watkins. "For men, it's more functional," he added. Watkins pointed out that, for example, women are more likely to post pictures of social gatherings with friends, while men are more likely to post pictures of hobbies, or post a political or pop-culture related link. Question: What's the popular viewpoint of ordinary people about the function of social media websites? They think _ . - It is positive to personal ties - It has negative effects on personal ties - It makes no difference to personal ties - It has both good and bad effects to personal ties
It has negative effects on personal ties

(Question)
Read the following article and select the best answer. Article: The first ting we do is to put an APB and this goes to all the police stations in the country. Next we telephone the hospitals. Often the person we are looking for has been in an accident. Then we might try parents, friends or relatives they might be with. We try to follow their movements and to find the last person they saw in local or national papers--especially papers they might read. There are other things we can do: put posters in places where they might be, go on television. Here in America there is a magazine in which there are photographs of missing children. This is often the last hope. Of course, with nearly two million missing children every year, we can't do all these things for everyone. We haven't got the time, or the money , or the people who work for it. Question: According to the passage, when they are looking for a missing child, they - can always find him - couldn't always try every way mentioned above - just try one way or another - won't give up until they find him
(Answer)
couldn't always try every way mentioned above

Ques: Read the following article and select the best answer. Article: People travel for a lot of reasons.Some travelers go to see battlefields or religious shrines.Others are looking for culture,or simply want to have their photos taken in front of famous places.But most Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it.Residents of cities like London,Copenhagen,and Amsterdam spend a lot of their winter in the dark because the days are so short and much of the rest of the year is in the rain.Every summer,more than 25 million people travel to Mediterranean resorts and beaches for their vacation.They all come for the same reason: sun. The huge crowds mean lots of money for the economies of Mediterranean countries.Italy's 30,000 hotels are booked every summer.And 13 million people camp out on French Beaches,parks,and roadsides.Spain's long sandy coastline attracts more people than anywhere else.37 million tourists visit yearly,or one tourist for every person living in Spain. But there are signs that the area is getting more tourism than it can handle.The Mediterranean is already one of the most polluted seas on earth.And with increased tourism,it's getting worse.The French can't figure out what to do with all the garbage left by campers around St.Tropez.And in many places,swimming is dangerous because of pollution. None of this,however,is damaging anyone's fun.The Mediterranean gets more popular every year with tourists.Obviously,they don't go there for clean water.They stand traffic jams and seem to like crowded beaches.They don't even mind the pollution.No matter how dirty the water is,the coastline still looks beautiful.And as long as the sun shines,it's still better than sitting in the cold rain in Berlin,London,or else. Question: Which of the following will damage the tourists' fun at Mediterranean resorts and beaches? - Polluted water. - Crowded buses. - Traffic jams. - Rainy weather
Ans: Rainy weather

Ques:Read the following article and select the best answer. Article: While most people consider that laughter is one of the nature's great treatments for a whole range of mental and physical diseases, it is still a serious scientific subject that researchers are trying to figure out. "Laughter is social." says Robert R. Provine, author of the book "Laughter: A Scientific Investigation", who has been studying laughter for decades. "Almost all people laugh 'ha-ha-ha' basically the same way. Whether you speak Mandarin, French or English, everyone will understand laughter. There is a pattern generator in our brain that produces this sound. Laughing is also a good way of communicating. Babies laugh long before they speak. No one teaches them how to laugh. They just do it. People may laugh at a prank on April Fools' day. But surprisingly, only 10 to 15 percent of laughter is the result of someone making a joke. Laughter is mostly about social responses rather than reaction to a joke. Deaf people laugh without hearing and people on cell phones laugh without seeing, which shows that laughter isn't dependent on a single sense but on social interactions. And laughter is not just a human thing. Chimps tickle each other and even laugh when another chimp pretends to tickle them. Jaak Panksepp studies rats that laugh when he tickles them. It turns out rats love to be tickled. They return again and again to the hands of researchers tickling them, Panksepp's video shows. By studying rats, scientists can figure out what's going on in the brain during laughter. It has been found that laughter in rats produces a chemical that acts as an antidepressant and anxiety-reducer. Scientists think the same thing probably happens in humans, too. This would give doctors a new chemical target in the brain in their effort to develop drugs that fight depression and anxiety in people. Even so, laughter itself has not been proved to be the best medicine, experts said. "No study has shown that laughter produces a direct health benefit," Provine said, "largely because it's hard to separate laughter from just... Question: Why does the writer say "laughter is mostly about social responses rather than reaction to a joke"? - because people can communicate with each other by laughing. - because laughter is the same sound in all the human's languages. - because laughter is considered a basic language all people can learn. - because everyone can understand the meaning of the word laughter.

Ans:
because people can communicate with each other by laughing.
