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, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, 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.

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 |
The brain operation was made possible mainly by .

A.a, b, c, d | B.c, a, b, d | C.c, b, d, a | D.b, c, d, a |

Several years ago, I had a huge falling out with one of my best friends. So huge, in fact, that now I can’t even remember what happened.
In the past nine years, I’ve seen her twice, and each time we’ve been polite but distant. And that troubles me because we were once that close to each other. I’d like nothing more than to go back nine years, and continue our friendship. But how? How do you reconnect with friends you’ve lost throughout the years?
Linking to your past
The desire to reconnect with lost friend isn’t unusual. Why? Because friends link us to the past. “Friends from years ago are custodians(监护人) of our past,” says Sandy Sheehy, author of Connecting” The Enduring Power of Female Friendship.
Although you can’t share information about your past with friends you’ve met recently, you don’t have a shared history with them. So you wind up only telling them about your past, rather than sharing it with them.
But many people never try to reconnect. Women especially have trouble taking the first step. Shyness or fear that the other person doesn’t want to reconnect often stops many women. And that shouldn’t be. Your friends probably want to be in touch with you as much as you want to be in touch with them.
Searching for friends
Fortunately, finding lost friends isn’t as difficult as it once was, thanks to tools like the Internet. Our experts offer these suggestions for locating contact information:
Search Internet sites designed to locate people like classmates.com and switchboard.com.
Contact your high school or college alumni(校友)office to request current address information.
Surf online yellow pages. Check current phone records from your friend’s hometown.
Network with other friends who might have known your friend.
Get in touch with any of her relatives(亲戚), if you know where they live. If you know where she works, find the company’s web site and search the directory of personnel.What ‘s the subject discussed in the passage?

Save the Animals
Animals are natural resources(资源) that people have wasted all through our history.
Animals have been killed for their fur and feathers(羽毛), for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid(禁止) the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.Animals are important to us mainly because __________.

About 809 primary school pupils from Southwest China’s quake-hit Sichuan Province arrived in eastern Shandong Province on a special train to attend classes there. The pupils, all from Leigu Township, Beichuan County, a badly-hit area in Sichuan, will study for about two months in schools in Shandong’s capital city of Jinan.

As we all know, robots are playing an important role in our daily life at present. Now South Korean schoolchildren see robot teachers in the classroom at an elementary school in Seoul. Robot teachers – who never get angry or make sarcastic (讽刺) remarks--- have been a hit with pupils during a pilot project in some South Korean schools, a government report said Thursday.
Elementary school children responded favourably to the robotic teachers, the Ministry of Knowledge Economy said, citing a survey by educational researchers.
English-teaching robots were sent to three provincial schools for eight weeks starting in late December.
And programmable electronic devices looking like robots, which teach math, science and art, were used in 10 Seoul schools for five weeks from November.
The researchers found that the English-teaching robots helped raise interest in the language and boosted the confidence of students.
“Tele-presence (远程呈现)” robots are controlled remotely by an English teacher and are equipped with a microphone and video camera. Autonomous units use voice-recognition software to interact with children .
The government has expressed interest in robots to give rural school children more learning opportunities.
“The machines spurred creativity and had a positive influence on the attitude of students,” a ministry official told Yonhap news agency.
Officials in charge of the project are working to improve the quality of robot teaching and iron out glitches (小故障)before any decision to expand (扩大) their use.What’s the writer’s purpose of writing the passage?
A.To show South Korean schoolchildren don’t like their teachers |
B.To prove robot teachers are better than real teachers. |
