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(装置),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.
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.

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, and then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain’s temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
1. The biggest difficulty in operating on the damaged brain is that _______.
A. the time is too short for doctors
B. the patients are often too nervous
C. the damage is extremely hard to fix
D. the blood-cooling machine might break down
2.The brain operation was made possible mainly by _______.
A. taking the blood out of the brain
B. trying the operation on monkeys first
C. having the blood go through a machine
D. lowering the brain’s temperature
3.With Dr. White’s new idea, the operation on the damaged brain _______.
A. can last as long as 30 minutes
B. can keep the brain’s blood warm
C. can keep the patient’s brain healthy
D. can help monkeys do different jobs
4. What is the right order of the steps in the operation?
a. send the cooled blood back to the brain
b. stop the blood to the brain
c. have the blood cooled down
d. operate on the brain
A. a, b, c, d B. c, a, b, d
C. c, b, d, a D. b, c, d, a
If women are mercilessly exploited(剥削) year after year, they have only themselves to blame. Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are always taken advantage of by the designers and the big stores. Clothes which have been worn only a few times have to be put aside because of the change of fashion.
Changing fashions are nothing more than the intentional creation of waste. Many women spend large sums of money each year to replace clothes that have hardly been worn. Women who cannot afford to throw away clothing in this way, waste hours of their time changing their old-fashioned dresses. Skirts are lengthened or shortened; neck-lines are lowered or raised, and so on.
No one can claim that the fashion industry contributes anything really important to society. Fashion designers are rarely concerned with necessary things like warmth, comfort and durability (耐用). They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort, as long as they look right. There can hardly be a man who hasn't at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or picking her way through deep snow in high heeled shoes.
When comparing men and women in the matter of fashion, the conclusions to be drawn are obvious. Do the constantly changing fashions of women's clothes, one wonders, reflect basic qualities of inconstancy and instability? Men are too clever to let themselves be cheated by fashion designers. Do their unchanging styles of dress reflect basic qualities of stability and reliability(稳定耐用)? That is for you to decide.
1. Designers and big stores always make money_________.
A. by mercilessly exploiting women workers in the clothing industry
B. because they are capable of predicting new fashions

2. To the writer, the fact that women change their old-fashioned dresses is seen as___.
A. a waste of money
B. a waste of time
C. an expression of taste
D. an expression of creativity
3. New fashions in clothing are created for ___________.
A. the commercial exploitation of women
B. the women's strength of character
C. basic qualities of inconstancy and instability
D. an important contribution to society
4. By saying "the conclusions to be drawn are obvious" ( Line One to Line Two, Paragraph Four), the writer means that ___________.
A. women's inconstancy in their choice of clothing is often laughed at
B. women are better able to put up with discomfort
C. men are also exploited greatly by fashion designers
D. men are more reasonable in the matter of fashion

The world’s first subway was built in London in 1863. At the time，the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work, they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems，the idea of the London Underground，the first subway system，was born.
The plans for building the Underground met with several problems and delays，but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3.7 miles) long. About 30，000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed)，and pleasant decorations inside each of the cars. However, the smoke from the engine soon filled the air in the tunnels with ash and soot(煤灰), as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems，riding in the Underground did catch on. It carried 9 million riders in its first year.
