China news, Beijing, Feb. 9 – Housing price in China has always aroused heated discussions among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.

Although the average price of residential houses in the United States, after converted to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US.

The high housing sales price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?

At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.

Most children, even the youngest of children, are delighted to be around and dogs. But these pets carry plenty of germs and allergens（过敏原）prompting researchers to ask: Are cats and dogs really safe for children?

A study finds that, contrary to many parents' fears, owning cats or dogs does not increase a child's risk of developing allergies, and in fact, may actually protect them. The study's lead author, Dr. Dennis Ownby of the Medical College of Georgia, says that even he was "very surprised" by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.

By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.

Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps "exercise" their immune systems early in life so that they're better able to resist allergic diseases later.

"There's something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response," said Dr. William Davis.

And while researchers are not encouraging parents to buy dogs or cats just to reduce a child's allergy risk, they say if a family already has one or more animals, there's no need to get rid of them.

1．Why do the researchers feel “very surprised” by the results of the study?

A．Because the results are contrary to their expectation.

B．Because so many children are playing with cats and dogs.

C．Because parents are so much worried about their children.

D．Because children with animals may develop allergies easily.

2．Compared with children who have pets, those who haven’t .

A．will lose the chance to develop immune system

B．may suffer allergic disease more often

C．will reduce the harm from bacteria

D．can keep doctors away

A．pet are ill-treated by their owners

B．less families would like to own cats and dogs

C．keeping pets is a good way to keep children healthy

D．the results of the study can make families with pets feel at ease

4．The underlined word “it ” in the fifth paragraph refers to .
