When the People's Republic of China was founded in 1949, there were more than 3,000 hutong.Most of the city's population lived in this traditional housing.But with the modernization of the city in the 1980s and early 1990s, many hutong were pulled down to build roads, skyscrapers and modern houses. The government has recognized the importance of hutong to Chinese cultural heritage .In 2002, Beijing listed 40 protected historical zones and increased its efforts to restore some key relics and older streets in the city.Nearly 500 hutong have survived. Hutong that still exist are like oases of calm surrounded by the noisy city.Walking through them, it's common to see groups of elderly citizens sitting together playing cards, mahjong or Chinese chess.In the early mornings and evenings, they gather to practice traditional forms of exercise such as taijiquan as well as dancing and singing folk songs or Peking Opera.Hutong have become a museum of Beijing's folk customs and history.

Q: Read the following article and select the best answer. Article: A new study suggests that early exposure to germs strengthens the immune system. That means letting children get a little dirty might be good for their health later in life. The study involved laboratory mice. It found that adult mice raised in a germ-free environment were more likely to develop allergies, asthma and other autoimmune disorders. There are more than eighty disorders where cells that normally defend the body instead attack tissues and organs. Richard Blumberg,who led the study,is a professor at Harvard Medical School in Boston,Massachusetts. He says,in 1989,medical researchers who sought to explain these diseases, first discovered that the increasing use of antibacterial soaps and other products, especially early in life, could weaken immune systems. Now, Dr. Blumberg and his team have what is the first biological evidence to link early exposure to germs to stronger adult immune systems. They say this exposure could prevent the development of some autoimmune diseases. In the adult germ-free mice, they found that inflammation in the lungs and colon was caused by so-called killer T cells. These normally fight infection. But they became overactive and targeted healthy tissue--an autoimmune condition seen in asthma and a disease called ulcerative colitis . Dr. Blumberg says the mice raised in a normal environment did not have the same reaction. He says their immune systems had been "educated" by early exposure to germs. Rates of autoimmune disorders are rising worldwide, but mostly in wealthier, industrialized countries. According to Dr. Blumberg, it might be high time that people were warned to be more careful with the early use of antibiotics and the prescription from their doctors. Rob Dunn is a professor of ecology and evolutionary biology at North Carolina State University in Raleigh. He says the new study does not mean people should stop washing. "Wash your hands , but don't do it with antibacterial soap. Let your kids play in a reasonable amount of dirt and get outside and get... Question: To keep healthy in the future, children had better _ . - play in a dirty environment once in a while - live in a germ-free environment - use plenty of antibacterial soaps - stay in under developed countries

Read the following article and select the best answer. Article: Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening. One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one's own. Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one's free time digging, planting, watering and doing other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of one who has shared the secret of Nature. Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight's (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night. Question: One can use the same money for _ to buy a little house with a garden in the country. - getting a small flat with a garden - having a small flat with a garden - renting a small flat without a garden - buying a small flat without a garden
renting a small flat without a garden
