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.

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

A. APEC                              B. Chinese scientist   

C. the APEC Center for Technology Foresight     D. Nano-technology

2.The length of a nanometer equals to ______.

    A.  meter         B.  meter      C.  meter        D.  meter

3. We can imply from what David Minns said that _________.

A. Nano-technology could only be used to invent new objects.

B. Nano-technology could be widely used to produce or invent objects.

C. Nano-technology is a money-consuming technology.

D. Nano-technology can not be used to improve the service of Internet.

4. Compared to steel, carbon nano-tubes are ________.

A. stronger and lighter      B. lighter but as strong

C. stronger but as light                                     D. poor in quality

　　Twenty years ago, kids in school had never even heard of the Internet. Now, I'll bet you can't find a 1 person in your school who hasn't 2 heard of it. In fact, many of us use it on a regular basis and can even use it at 3 . The "net" in Internet really stands for network. A network is two or more computers 4 together so that information can be 5 or sent from one computer to 6 . The Internet is a vast 7 for all types of information. You may enjoy using it to do 8 for a school project, downloading your favorite songs or 9 with friends and family. Information can be found 10 web pages that companies, organizations, and individuals (个人) create. It's like a giant bulletin board that the whole world uses! But since anyone can put 11 on the Internet, you also have to be careful and use your best 12 and a little common sense.

　　Just 13 you read something on a piece of paper someone puts on a bulletin board doesn't mean that it's good information, or even correct, for that matter. You have to be sure that whoever posted the information knows what they're talking about, 14 if you're doing research! But what if you're just e-mailing people? You still have to be very 15 if you've never met the person that you're communicating with online. You could be doing something 16 ! You should never give out any 17 information to someone you don't know, not even your name! And just like you can't 18 the information on every website out there. You can't 19 on what strangers you "meet" on the Internet tell you either. In the same way that you could 20 things about yourself to tell someone, as someone else could do the same to you!
