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

All right! Enough cookies,cola, and chips! It seems that junk food is all that the children want to eat these days.Television controls their tastes.The kids see well-known personalities eating potato chips, candy and other processed food, and they want to be like their heroes.How do they do it?They eat the same food. I wish there were more characters like old Popeye（大力水手）, the sailor, who ate spinach（菠菜） and not French fries.
Now I don't expect my children to eat healthy food because I like brown rice, beans, and fresh vegetables. I'm glad to cook traditional meals of meat and potatoes for them. I really can't be too upset with the kids because most adults aren't careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can't eat hot dogs, with all those preservatives（防腐剂）, and hamburgers are filled with chemicals so that they look better. Besides the meat, they had sugar-filled cookies and cake, and of course, chips. I don't want the world to change because of me, but I think people should realize that there are alternatives(选择) to eating meat. They always tell me that I probably don't get my essential(必要的) proteins. I feel better than ever and I'm sure that it's because I'm a vegetarian(素食主义者). I would really like to see more television advertisements which show the benefits of good, healthy, natural food.
【小题1】According to the passage, it seems that ______.

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple

This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.

An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.

Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.

Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler

RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.

1. The article is intended to______.  

A. warn people of the possible risks in adopting RFID technology

B. explain the benefits brought about by RFID technology

C. will have more time to make friends

D. won’t feel shy at parties any longer

3. Passive RFID tags chiefly consist of        .

A. scanning devices              B. radio waves   C. batteries              D. chips

    Most people think a person’s taste in food is so unique and random that it couldn’t possibly reveal anything about his/her character.

    But other subtle(奇妙的) things that people do can help us make up our mind about a person’s character. Should we really be so quick to dismiss what a person eats?

    Dr. Alan Hirsch is a US neurologist (神经科医生) who specializes in the treatment of people who lose their sense of smell or taste.

    In order to investigate the possible link between people’s choices of snack food and personality, Hirsch quizzed a sample of 19, 400 people. He made all participants undergo two well-known personality tests.

    These tests define each of the volunteers according to widely accepted personality categories. Hirsch could then check his own results against these in order to find interrelation between their choice of snack food and personality type.

    Hirsch also tested the volunteers on questionnaires designed to assess depression, because depressive illnesses are known to coincide with losses of sensation and preferences for certain foods.

    The volunteers were then tested on their preference for snack foods and the pleasure value they assigned to each food. Hirsch also quizzed married partners on their choices to find out how people with different food choices differed in their compatibility (兼容性) for each other.

    The study revealed surprising links between perfectionism and the urges to chew tortilla (玉米饼) chips and even a connection between introversion (内向) and the consumption of cream crackers.

    Dr. Hirsch used the same technique of testing for associations between different personality types and the flavors of ice cream people prefer.

    Finally, while some will feel this test provides a good assessment of their personality, others will disagree with the assessment.

D. Believe It or Not

A car needs gas to run as your body needs food to work for you. Eating the right kinds of food is very important. A good eating habit can help your body grow strong if you take care of what you eat.

There are four main food groups altogether. The dairy group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all four main groups. With all of these foods together, you will be given enough energy during the day.

It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time or you may not have time for a good lunch. It may be easier to eat fish and chips for your supper all the time. But you will find yourself tired and you will not be able to think quickly.

Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having good eating habits with some exercise is the key to your health.

1.According to the passage, which of the following diets do you think is the best one?

A. Eggs, tomatoes and chicken.          B. Milk, bread, cabbages and beef.

C. Corn, fish, ice cream and pork.        D. Rice, beancurd, fish and chicken.

2.In this passage the writer mainly tells us that ______.

A. every person needs food to grow well

B. taking exercise can keep your body strong

C. the right kind of food with exercise will keep you healthy

D. enough energy helps people think more quickly
