It is difficult for doctors to help a person with a hurt brain. Without enough blood, the brain lives only three to five minutes. Sometimes the hurt brain gets better by itself. More often the doctors can't fix the hurt brain. Sometimes they are afraid to try something to help. It is dangerous to work on the brain. The doctor might make the person worse if he works on the brain.
Dr. Robert J. White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should try to make the brain become very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctors 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 opera-ted 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 temperature was 10 degrees. 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 were before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
Dr. White's idea works well on the monkeys. Are there other problems with human beings? Dr. White thinks doctors will use his idea on human beings. He thinks it will help people who have heart problems, too. A person doesn't have to die when his heart stops? doctors can start it again. The problem comes when the brain is without blood for three to five minutes—the person has a living body, but a dead brain. Maybe in the future, doctors will try Dr. White's idea. When the person's heart stops, the doctors will quickly try to cool the brain. They will have 30 minutes to start the heart again. Maybe there will be no problem with the brain.

At East China University of Science and Technology, students will get a coupon（优惠券）if they eat up their food. Students can collect coupons and exchange them for small gifts, such as books, magazines, mobile phone covers and hand warmers.
“It’s been such a surprise,” said Liang Zhaoyun, 19, a student at the university in Shanghai. “It has given us one more motivation to finish our food.”
The measure （措施） is part of a national “eat-up” campaign（行动） which is organized by students to deal with food waste on campuses（校园）.
Why only on campuses, you might ask? Because according to a report by Xinhna News Agency, students waste twice as much food as the national average（平均）.

Smaller than your fist, your healthy heart just goes on and on. It will beat more than 60 times a minute for 70 years or more. That’s something that most of us take for granted. But it’s an amazing fact.
60 times a minute for 60 minutes is 3,600 times. What physical thing can most of us do 3,600 times in one hour? Blink? Maybe. Tap our fingers on the desk? No. Jump up and down? Certainly not! But our heart keeps beating, hour after hour. Every day, it pumps almost 2,000 gallons of blood through our blood vessels(血管). It takes you about five years to drink 2,000 gallons of water.
And, unlike your knees or your back, your heart does all this work without ever complaining（抱怨）! You never know that it’s even there. Your heart is such a reliable “silent partner” that people forget to care for it. For many, the first indication（迹象）that their heart isn’t working properly is a serious heart illness! Over 650,000 Americans die of some kind of heart disease every year. Cancer kills 560,000, stroke kills 143,000, and accidents kill 118,000 Americans annually.
Like accidental deaths, many heart disease-related deaths can be avoided if people simply follow the advice of the experts. Unfortunately, most people seem to listen to a little voice in their head that says, “It won’t happen to me. ” So these people keep on smoking and drinking. They continue to eat too much meat. And their only “exercise” is getting off the sofa to get something out of the fridge. Please follow the following steps to keep your heart healthy.
