Simply by analyzing a drop of blood, a doctor will be able to diagnose a birth defect or even cancer when it is in the early stage; using new technology, a material lighter but much stronger than steel can be produced.

These may sound like dreams at present. But the dreams may soon come true as research findings in laboratories are being turned into products more rapidly in the new century, according to experts participating in the fourth Asia-Pacific Economic Cooperation (APEC) Technomart, a technology exhibition and trade fair in Suzhou.　　

"Most people think nano-technology（纳米技术）is too far-fetched to be real. But in fact nano-technology has been applied in a wide range of fields, such as medicine. It is coming into our daily life," said Cheng Jiachong from a Hong Kong-based nano-technology firm.

Nano-technology based on the nanometer, the unit of which is a billionth of a meter, enables scientists to have new concepts of disease diagnosis and treatment on a molecular（分子）and atomic scale, Cheng said.　　

By using nanometer particles, a doctor can separate the fetus cells（胚胎细胞）from the blood of a pregnant woman to see if the development of the fetus is normal. This method is also being used in the early diagnosis of cancer and heart disease, he said.　　

One of the most significant impacts of nano-technology is at the bio-inorganic materials interface, according to Greg Tegart, executive advisor of the APEC Center for Technology Foresight.　　

"By combining enzymes（酶）and silicon chips we can produce biosensors. These could be implanted in humans or animals to monitor health and to deliver corrective doses（剂量）of drugs," he told the participants a technology forum during the exhibition.　　

"Nano-technology could affect the production of nearly every man-made object, from automobiles, tires and computer circuits（电路）, to advanced medicines and tissue replacement, and lead to the invention of objects yet to be imagined," said David Minns, a special advisor to the National Research Council of Canada.　　

It has been shown that carbon nano-tubes are ten times as strong as steel, with one sixth of the weight, and nano-scale systems have the potential to make supersonic transport cost- effective and to increase computer efficiency by millions of times, he said.

The experts agreed that the APEC technology exhibition and trade fair provided many chances for exchanges of innovative ideas and products.

　 Garden building is considered an important part of Chinese culture. Some people say that if you have never walked through a Chinese garden, you cannot say that you have really visited China.

Traditional Chinese gardens are located(位于)in North China in such places as BeiHai Park, the Summer Palace, the Forbidden City. In larger imperial gardens, the main buildings are connected by an imaginary (虚构的) line in the middle of the garden on the north-south axis(轴). Other features (特征)of imperial gardens are colored-paintings, man-made hills and lakes.

　 Most private gardens are found in the south, especially in cities south of the Yangtze River. Private gardens were mostly built at one side or at the back of the houses. Around the beautiful scene are small open areas with beautiful shaped-doors through which visitors can enjoy the sights. They are open on all sides and are often near the water so that the whole scene can be enjoyed. Suzhou, known as the home of gardens, displays the most and the best Chinese traditional private gardens. Different parts of it are examples of the garden style of the Song, Yuan, Ming and Qing Dynasties.

　 The landscape garden contains a number of pleasant natural scenes and some fairy tales. The ancient Chinese used to call the garden landscape "Jing", which means "scene" in English. Good examples include the ten West Lake Scenes in Hangzhou, the twenty-four slim West Lake in Yangzhou and the eight Daming Lake Scenes in Jinan.

　　Faced with the threat of water shortages, Beijing and Shanghai will take effective measures to save water and protect water resources.

　　Beijing will stick more strictly to water saving policies through the readjustment（重新调整）of industrial structures. Beijing is expected to be short of 1 185 billion cubic meters of water by 2020. Beijing will shut down factories with high water consumption（消耗）and pollution including electric power, steel and paper manufacturing equipment. Advanced and water-saving technology will be introduced to new industrial projects in the capital city.

　　Grain-growing areas will be reduced to save ground water and more trees will be planted. Animal breeding and other “high efficient” agriculture with modern water-saving irrigation methods will be developed.

　　It is said that water used in agriculture will drop to 35 percent of the city's water consumption in 2010 from 43 percent in 1998,and the figure will continue to drop to 28~30 percent in 2020. Beijing will increase the speed of renovation（修复）of its urban water supply equipment. It is reported that more than 15 percent of water is lost during distribution（分布）. Water saving equipment and efficient management can save Beijing more than 537 million cubic meters by 2010.

　　Shanghai still faces key problems connected with its water resources and environments. Since 1998, the city has invested nearly US $ 169 million to treat its rivers, especially Suzhou Creek. The city's rivers have become noticeably clearer since putting it into action.

　　The government will provide a further US $ 24 million for the treatment of rivers and US $ 12 million to treat sewage（污物）.

　　This year's task is to improve the water quality at the three ports of Longhua, Yangshupa and Hongkou. Another emphasis to raise the water system is Songjiang New Area with a project worth US $ 4.8 million. Efforts will be made to improve public awareness about the need to protect water resources.

(1) How many measures has Beijing taken to save water and protect water resources?

[　　]

(2) Grain-growing areas in Beijing will be reduced because __________.

[　　]

A．grain can't fetch a good price in China

B．a lot of ground water will be saved by this means

C．Beijing helps to develop advanced industry

D．highly effective agriculture needs less farmland

(3) Beijing can save over 537 million cubic meters by 2010 by means of __________.

A．water-saving equipment

B．effective management

C．artificial rain fall

D．reducing water pollution
