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.
【小题1】Realization of the dreams mentioned in the first paragraph will mainly base on ________.

A．meter

B．meter

C．meter

D．meter

Modern inventions have speeded up people’s loves amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boats (吹嘘) of saving precious seconds in handling tasks.

All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so.  We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind on another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientist; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about.

However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed constant activity that we find it difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.

There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestor faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence.

68. The new products become more and more time-saving because         .

A. our love of speed seems never-ending

B. time is limited.

C. the prices are increasingly high.

D. the manufactures boast a lot.

The “Doorman”
