Article: One day last September, as Britney Spears was about to board a flight to Los Angeles from prefix = st1 /London, a blue bottle fell out of her purse. She quickly put it back in, but not before the camera recorded the event. Neither Spears nor her spokesman was willing to comment on the contents of the bottle, but the next morning London's Daily Express published a page of pictures under the headline "EXCLUSIVE: POP PRINCESS SPOTTED AT AIRPORT WITH POT OF SLIMMING TABLETS." Spears was apparently carrying Zantrex-3, one of the most popular weight-loss pills now sold in theUnited States. The pill, which is sold at about fifty dollars for a month's supply, contains a huge amount of caffeine, some green tea, and three common South American herbs that also act as stimulants . It hit the U.S.market last March and has had _ . Millions of bottles have been sold, and during the Christmas season it was displayed in the windows of the nation's largest chain of vitamin shops, G.N.C. (It is so highly sought after that many of the stores keep it in locked counters.) Zantrex-3 is also sold at CVS, Rite _ Aid, Wal-Mart, and other chains, and over the telephone and on the Internet. If you type "Zantrex" into Google, more than a hundred thousand pieces of information about it will appear. At any moment, there are scores of people sell it on eBay. Perhaps the most interesting thing aboutthe success story of Zantrex-3, however, is that _ is far from unique. There are hundreds of similar products on the market today, and they are bought by millions of Americans. And though Zantrex's producer makes some exciting statements ("the most advanced weight control compound period"), so do the people who sell Stacker 2 and Anorex along with those who sell Carb Eliminator and Fat Eliminator. Almost all of these compounds suggest that they can help people lose weight and regain lost energy, and often without diet, exercise, or any other effort. Question: Britney Spears is a / an _ .

Read the article and select the best answer. Article: Dr. Wiseman started the "laugh lab" project in September 2001. It is the largest study of humor. Participants are invited to log on the laugh lab website, give a few personal details, tell their favorite jokes and judge the jokes told by other people. Their project will last for a year, and the organizers hope to finally discover the world's funniest joke. But there is also a serious purpose. The researchers want to know what people from different nations and cultures find funny. And they want to find out the differences between male's and female's sense of humor. The idea is that if we want to understand each other, we have to find out what makes us laugh. This is a subject that has long interested psychologists and philosophers . Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves. By December 2001 over 10,000 jokes had been submitted . This gave the scientists enough evidence to make early conclusions. It seems that men and women do have different senses of humor, for example. "Our findings show the major differences in the ways in which males and females use humor," said Dr Wiseman. "Males use humor to appear superior (,) to others, while women are more skilled in languages and prefer word play." Researchers also found that there really is such a thing as a national sense of humor. The British enjoy what is usually called "toilet humor". But the French like their jokes short and sharp, "You're a high priced lawyer. Will you answer two questions for $ 500?" "Yes. What's the second question?" The Germans are famous for not having a sense of humor. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality. Perhaps that proves the point. Is this joke funny? I don't know, but let's say yes, just to be safe. Dr Wiseman and his workmates also submitted jokes created by computer.... Question: The scientist started the "laugh lab" project _ . Options: A: to find the funniest joke in European countries B: to know what funny people are from different nations and cultures C: to find out the differences between the male's and female's sense of humor D: to get more personal details about participants

Read the article and select the best answer. Article: BEUING (Associated Press ) --China has a growing middle class, a tradition of expecting education and 21 million new babies every year. Selling educational toys should be easy. While China may be the world's biggest toymaker, many of the best are exported . Department stores here do not have enough high quality toys. It is said that the demand for educational toys is low. A US company, BabyCare, is trying to change that with a new way to sell toys in China. BabyCare works basically together with doctors in Beijing hospitals. People who join the company's "mother club"can get lectures and newsletters on baby and child development at no extra cost, if they agree to spend 18 dollars a month on the company's educational toys and childcare books. "We want to build a sevenyear relationship with those people," said Matthew J. Estes, BabyCare's president. "It starts during pregnancy , when the anxiety and needs are highest." BabyCare works on a onetoone basis. Doctors, nurses, and teachers paid by BabyCare advise parents, explain toys that are designed for children at each stage of development to age six. BabyCare opened its first store in China last June in a shopping center in central Beijing and another near Beijing Zoo. It plans to have 80 stores in China within six years. It is a new model for China and develops a market in young children's education and health that no other companies are in. Question: BabyCare is developing its business in China by. Options: A: opening stores in Beijing hospitals B: offering 18month courses on childcare C: setting up children's education centers D: forming close relationships with parents
