　　Chinese children will be able to get a taste of adult working life in a theme park planned for Hang-zhou city,East China's Zhejiang Province.The Kids City,the first of its kind in China,will allow children aged five to ten to try out jobs of their choice after it opens in October 2008.
　　Located in eastern Hangzhou,the indoor entertainment and educaion park,similar to "Kidzania" in Mexico and Japan,offers more than 50 professions,including pilot,doctor,police officer and lawyer,according to Hangzhou Youth Activity Center(HYAC),the organizer of the park,The park will be a 7:10 scale (比例尺) city with streets,hospitals,museums,supermarkets, schools,airport and other facilities.Construction has begun on the indoor section.
　　Inside the 7,000-square-meter city,every kid would get a bank account holding special money that they can only spend in the park.They could earn more money by working in different booths or workshops.One job would take about half an half an hour and the whole tour would usually last five to six hours."The interactive(交互式) experience will help kids to learn about the adult life,which is good for their future career planning.They will have a lot of fun here,"said Huang Jianming,chief of HYAC.Parents are not allowed to enter the city,but they can take pictures from outside the huge glass house.
　　The ticket price has not been decided yet.But HYACsaid it might be lower than Kidzania Tokyo's and around several hundren yuan.With the majority of investment(投资) coming from the government,the project also needs financial support from companies and organizations,according to HYAC.
　　The world's first Kidzania was opened in Mexico City in 1999.It has turned out to be a huge success receiving about 800,000 visitors every year.In 2006,Kidzania opened its Tokyopark in Japan,which also became an attraction to kids."We are confident that the Chinese version(版本) wll be very successful."said Huang.
　　60.The theme park is aimed at letting the kids_______.
　　　A.work with adults B.experience adult careers
　　　C.imitate adults looking after a family D.watch adults work
　　61.The Kids City will________.
　　　A.be more than half the size of Hangzhou City
　　　B.consist of two parts,one larger than the other

Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health．
This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased．Apple, for example, doesn’t want iP hones to come closer to you than 1．5 centimeters; Research In Motion, Blackberry’s manufacturer, recommends 2.5 centimeters．
If health issues arise from cell phone use, the implications are huge．Voice calls - Americans chat on cell phones 2．26 trillion minutes annually - generate $109 billion for the wireless carriers．
Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled.
　　Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
　　"Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
　　Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says.
　　Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.
　　Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen.
【小题1】We can infer from the passage that________．

Scientists are closely concerned with the structure of buildings and with the quality of building materials． The World health Organization （WHO) observes that the introduction of air conditioning and energy conservation （保护) measures have been accompanied by growing problems of indoor air quality． Some pollutants arise from insulation （隔音) products, some from moving cars, and others from modern housing materials． As many Europeans spend up to 90% of their lives in buildings, the health effects of the indoor climate are very important．

　　Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde （甲醛)． Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes． Paint, lacquer, etc． can also release dangerous gas into indoor air．

　　Construction materials can cause serious damage, especially when they contain asbestos（石棉）． Asbestos is naturally present in rock formations worldwide． It belongs to a family of mineral substances made up of solid, non-combustible（非易燃品） fiber． These properties make asbestos a highly sought-after construction material． As early as 1931, however, public health officers in the United Kingdom revealed the connection between breathing in asbestos dust and such diseases as lung cancer．

　　The land on which a building is sited may also contribute to pollution． Some kinds of granite or similar rocks contain traces of radium． As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms． The better the homes are insulated, the more is the dangerous gas in indoor air． The main effect of this dangerous gas on health is to increase the risk of lung cancer．

What is the main idea of the passage?

    A．Some building materials pollute indoor air．

    B．Some factors cause indoor air pollution．

    C．Asbestos can cause lung cancer．

    D．The land on which houses are built contributes to indoor pollution．

Why are Europeans particularly concerned with building materials?

    A．Lots of building materials there are radioactive．

    B．They stay home up to 90% of their lives．

    C．They have a high rate of lung cancer．

    D．They spend most of their time indoors．

Why is asbestos a sought-after building material?

    A．It is a kind of insulation foam．

    B．Asbestos will not give out dangerous gas．

    C．This material is not easy to catch fire．

    D．It is rarely present in rock formations．

Why should we be careful about the land on which a building is to be sited?

    A．To determine whether the land is firm enough for a building to be sited on．

    B．To make sure that the land contains no radioactive material．

    C．To make certain that the land releases no formaldehyde or other gases．

    D．To check whether it contains any combustible materials．

American cities are similar to other cities around the world. In every country cities reflect the values of the culture. Cities contain the very best aspects of a society: opportunities for education employment and entertainment. They also contain the very worst parts of a society: violent crime, racial(种族) conflict and poverty. American cities are changing just as American society is changing.   　　

After World War II city residents became wealthier. They had more children. They needed more space. They move out of their apartments in the city to buy their own homes. They bought houses in the suburbs areas near a city where people live. These are areas without many offices or factories. During the 1950s the American “dream” was to have a house in the suburbs.

　　Now things are changing. The children of the people who left the cities in 1950s are now adults. They unlike their parents want to live in the cities. Many young professionals, doctors, lawyers and executives(主管人员) are moving back into the city. Many are single; others are married but often without children. They prefer the city to the suburbs because their jobs are there; they are afraid of the fuel shortage; or they just enjoy the excitement and opportunities which the city offers.

    This population shift(转变) is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these people do not have enough money to stay in the cities.

     Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems and conflicts. One thing is for sure：many dying cities are alive again.
