On October 5, Tu was awarded the 2015 Nobel Prize in Physiology or Medicine. She shared the prize with two other scientists from the US and Japan. Tu is the first native Chinese person __3.(receive)a Nobel Prize in natural sciences.

Tu was modest about receiving the award: “It’s a success for the whole research team.” She also thinks 4. is scientists’ duty to fight for the health of all humans.

When Tu joined the national research team to find the medicine 5. could fight against malaria in the 1960s and 1970s, things were hard. The team didn’t have advanced equipment back then. Tu used to test 6. (medicine) by eating them herself. Her team searched old Chinese medicine books 7. hand and tested over 2,000 traditional recipes.

Once Tu 8. (return)home after traveling for six months. Her little daughter didn’t recognize her and hid from the “strange woman”. To do research, Tu also had to move around a lot.

Finally, Tu found artemisinin (青蒿素)in sweet wormwood in 1971. She spent the next decades 9. (try) to improve the medicine. According to World Health Organization, about 200 million people suffer 10. malaria around the world, and about haft a million die each year. Artemisinin is stir the most effective treatment against malaria known today.

Tu never complains about how hard she works. “I feel more rewarded when I see so many cured patients,” she said.

Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived(复活). Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues. Death is then unchangeable and final.

Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body’s metabolism(新陈代谢), cooling delays the processes leading to biological death.

To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous(自发的)breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal.

D. delay the coming of biological death.

3.How did the scientists put Keta into clinical death?

A. By putting her to sleep, lowering her temperature and draining her blood.

B. By surrounding her body with ice-bags and draining her blood.

C. By lowing her blood pressure and stopping her heart from beating.

D. By draining her blood, lowering her blood pressure and stopping her breathing.

A. her heart beat again.

B. she regained her normal breath.

It was unusually quiet in the emergency room on December 25.

I was the nurse on duty that day. I didn’t think there would be any patients, sighing about having to work on Christmas. Just then five bodies showed up at my desk, a pale woman and four small children.

“Are you all sick?” I asked.

“Yes,” she said weakly and lowered her head.

But when it came to descriptions of their problems, things got a little unclear. Two of the children had headaches, but the headaches weren’t accompanied by the normal body language of holding the head or trying to keep it still. Two children had earaches, but only one could tell me which ear was affected. The mother complained of a cough but seemed to work to produce it.

Something was wrong, but I didn’t say anything but explained that it might be a little while before a doctor saw her. She responded, “Take your time; it’s warm here.”

Then I checked the chart after the admitting clerk had finished registering the family. No address—they were homeless. The waiting room was warm.

I looked out at the family gathering close together by the Christmas tree. The little one was pointing at the television and saying something to her mother. The oldest one was looking at something on the Christmas tree.

I went back to the nurses’ station and mentioned we had a homeless family in the waiting room. The nurses, complaining about working on Christmas, began to feel pity for a family just trying to get warm on Christmas. The team went into action, much as we do when there’s a medical emergency. But this one was a Christmas emergency.

We were all offered a free meal in the hospital cafeteria on Christmas Day, so we claimed that meal and prepared a banquet for our Christmas guests. We needed presents. We put together oranges and apples in a basket. We collected from different departments candies, crayons and other things available that could be presents. As seriously as we met the physical needs of the patients that came to us that day, our team worked to meet the needs of a family who just wanted to be warm on Christmas Day.

Later, as the family walked to the door to leave, the four-year old came running back, gave me a hug and whispered, “Thanks for being our angels today.”
