世纪百通期末金卷系列答案Alan worked in an office in the city. He worked very hard and really looked forward to his holiday. He usually went to the seaside, but one year he saw an ad. in a newspaper “Enjoy country life. Spend a few weeks at William Farm. Good food, fresh air, horse riding, walking, fishing…”

Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition（眼睛识别 program has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology（技术） will take the place of all other ways of finding out who people are.
However, scientists are also working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get dirty like hands or fingers, and even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. However, some other programs may only be 51% correct at present. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.
In the future your computer will be looking you in the eye. So smile!

TOKYO, JAPAN--What do you do when you see a cockroach (蟑螂）？ Do you hit it with a newspaper? Do you step on it?
When researchers at Tokyo University see a cockroach, they take the remote control and make the cockroach turn around, run left or right, or go forward. These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has in it a microprocessor(微处理器）.Then researchers can send signals from the remote control to the pack. The signals control the movements of the cockroaches.
Why does anyone want to control a cockroach? “Insects can do many things that people can’t,” says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble(瓦砾）to look for people or move under doors to find information about someone.
This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $ 5 million for this research.
First, the researchers breed (培育)hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae(触须）. They put small packs where the antennae were. The packs weigh about three grams, or about two times the weight of the cockroaches themselves. “Cockroaches are very strong,” says Ralph Holzer, who is a researcher at Tokyo University. “They can lift 20 times their own weight. ”
With a remote control, the scientists send signals to the packs. When a cockroach gets the signal, it moves. The problem is that the cockroaches don’t always move in the right direction.

| C．They can breed hundreds of cockroaches. |
| D．They can search for those people in rubble after an earthquake. |
| A．by removing their wings |
| B．by sending signals from the remote control |
| C．by using very small cameras |
| D．by removing their antennae |
| A．The cockroachcs sometimes clon;t move. |
