Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two stages---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(復(fù)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 lengthen 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(麻醉的) sleep. By slowing down the body’s metabolism(新陳代謝), 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(流光466) blood from an artery(動脈). 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(自發(fā)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(注射器)and ran with it around the room. Her behavior differed little from that of a healthy animal.

1.For a person who suffers from the clinical death ___________.

A. he still has the possibility of getting back to life

B. his most important organs are damaged.

C. he can not avoid final death.

D. he is still very much alive

2.Scientists try to make the time of clinical death longer in order to___________.

A. slow down the body’s metabolism.

B. bring vital cells and tissues back to active life.

C. delay the coming of biological death.

D. cool the organism.

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

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

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

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

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

4.All of the following indicate that the monkey has almost restored to her original physical state except the fact that___________.

A. her heart beat again.

B. she regained her normal breath.

C. she rejected a penicillin injection.

D. she acted as lively as a healthy monkey.

American black bears appear in a variety of colors despite their name. In the eastern part of their range, most of these bears have shiny black fur, but in the west they grow brown, red, or even yellow coats. 1. Even in the same litter (一窩幼崽), both brown and black furred bears may be born.

Black bears are the smallest of all American bears, ranging in length from five to six feet, weighing from three hundred to five hundred pounds. 2.

3. However, if attacked, most can climb trees and cover ground at great speeds. When angry or frightened, they are formidable enemies.

Black bears feed on leaves, herbs, fruit, berries, insects, fish, and even larger animals. 4. Unlike squirrels, woodchucks, and many other woodland animals, bears do not actually hibernate. Although the bear does not eat during the winter months, sustaining itself from body fat, its temperature remains almost normal, and it breathes regularly four or five times per minute.

5. They prefer to live in caves. Baby black bears are born in January or February after a gestation(懷孕) period of six to nine months, and they stay with their mother until they are fully grown or about one and a half years old.

Nobel Prize Winner Studied How People Spent Their Money

The winner of the 2015 Nobel Prize in Economic Sciences studies how people spend their money.__ 1.__The Royal Swedish Academy of Sciences is presenting the Economics Prize to Professor Angus Deaton of Princeton University in New Jersey. The Nobel committee says his research has mainly dealt with three questions:__2.__How much of society's wealth is spent and how much is saved? And, how do we best measure and study well?being and poverty?

Mr. Deaton used household surveys to collect detailed information about how families spend their money. People often asked him the question why he paid so much attention to household information. __3.__“Well, it's individually... it's about people in the end. You have to understand what makes people tick, and what's good for them. And for me it's always been about trying to understand behavior and to try to infer from that behavior, you know, how people are doing.”

The Nobel committee said Mr. Deaton's research has shown “how the clever use of household data can shed light on(闡明)issues such as the relationship between income and calorie intake, and the extent of gender discrimination with the family.”__4.__rather than theoretical ideas. Subjects of his research have included happiness, well?being and aging. At a press conference last month, the Nobel Prize winner said he was pleased that his work had been recognized. __5._“I think we have had a remarkable decrease for the past 20 to 30 years. I do expect that to continue,” he said.

A. Are you a saver or a spender?

B. He told reporters he believed poverty would decrease.

C. How do consumers distribute their spending among different goods?

D. He said that his studies were mainly about people and their behavior.

E. He also has explored how spending can affect both living conditions and poverty.

F. He examined the close relationship between poverty and the amount of calories in the food people ate

G. The Nobel committee also praised Mr. Deaton's work because it used detailed information about real people
