Article: A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.
Question: What is the passage mainly about?
Options: (A) Teens' sleep is linked to their relationship with people around them. (B) Lack of adequate sleep puts teens at risk of many bad consequences. (C) Modern technology has something to do with teens' sleep problems. (D) It is necessary for teens to join in sports and positive social activities.

Article: One's style of the dress reveals the human obsession with both novelty and tradition. People use clothing to declare their membership in a particular social group; however, the rules for what is acceptable dress for that group may change. In affluent societies, this changing of the rules is the driving force behind fashions. By keeping up with fashions, that is, by changing their clothing style frequently but meanwhile, members of a group both satisfy their desire for and obey the rules, thus demonstrating their membership in the group. There are some interesting variations regarding individual status. Some people, particularly in the West, consider themselves of such high status that they do not need to display it with their clothing. For example, many wealthy people in the entertainment industry appear in very casual clothes, such as the worn jeans and work boots of a manual laborer. However, it is likely that a subtle but important signal, such as an expensive wristwatch, will prevail over the message of the casual dress. Such an inverted status display is most likely to occur where the person's high status is conveyed in ways other than with clothing, such as having a famous face.
Question: According to the author, fashions serve all the following purposes EXCEPT
Options: (A) satisfying an interest in novelty (B) signaling a change in personal beliefs (C) displaying membership in a social group (D) following traditional rules
Asnwer: D
No

Article: SHANGHAI--The Shanghai World Financial Centre will be the tallest land-mark in the world after its completion this century in Pudong, according to the project's Japanese investors. The building will be located in the prime Lujiazui Zone in Pudong , on a 30,000-square-metre site. The building was originally designed to be a 94-floor office tower with a height of 460 metres. The project broke ground in 1997 but was later halted as a result of the financial crisis in Southeast Asia. "As the economy warms up, we are more confident about Shanghai and the whole prefix = st1 /Chinaand we are working hard to get the Project restarted as soon as possible," said Katsuyuki Takeuchi, vice-president and general manager of the Shanghai World Financial Centre Company. Its parent company, Japan-based Moil Building Co. Ltd, established the Shanghaisubsidiary as the operator responsible for this ambitious project. The design, which is undergoing revision in apian, will accommodate international high-tech businesses, department stores, art galleries, clubs and a five-star hotel. Unlike the gloomy economies of theUnited States, Europe andJapan,Chinaenjoys a strong growth with brighter prospects, Takeuchi said. More capital and businesses are expected to flow into Shanghai, which aims to become a world centre for trade and the financial industry--with Lujiazui as its showpiece. The layout of Luijiazui includes three tall buildings, one of which is the completed JinmaoTower, each rising above 400 metres, as designed by local government after holding an international design competition early last decade. Other buildings nearby fall in height gradually, creating a special shape against the skyline. The Shanghai World Financial Centre will be built as the peak of the mountain. "The peak will be safe thanks to the perfect design, advanced technology and the stable social and political environment in Shanghai," Takeuchi said, reassuring those who might be anxious about the safety of the soon-to-be world's tallest building.
