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.
For a person who suffers from the clinical death, _________.

A．his most important organs are damaged.

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

C．he can not avoid final death.

D．he is still very much alive

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．cool the organism.

D．delay the coming of biological death.

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.

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.

When Charles Stratton was five, he stopped growing. His mother took him to see the famous showman, P. T. Barnum. Mr. Barnum thought a small person would be the perfect addition to his show. He hired Charles' parents along with him, and they traveled the world together.

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid--we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk. Basilicus, a lizard (蜥蜴) native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we'd need huge feet that we could bring up to our ears in order to create adequate "hitting. “
But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a "non-Newtonian" liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(微粒) in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.
Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice, if you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!
Walking on water hasn't become a reality mainly because humans _______.

A．are not interested in it

B．have biological limitations

C．have not invented proper tools

D．are afraid to make an attempt

A．It is light enough to walk on water.

B．Its huge feet enable it to stay above water.

What is the function of the cornflour according to the passage?

A．To create a thick liquid.

B．To turn the water into solid.

C．To help the liquid behave normally.

D．To enable the water to move rapidly.

What is the author's attitude toward the idea of humans' walking on water?

A．It is risky but beneficial.

B．It is interesting and worth trying.

C．It is crazy and cannot become a reality.

D．It is impractical though theoretically possible.

When the swim season began, my 11-year-old daughter, Elizabeth, and I cut a deal. She would go to practice three times a week, and I wouldn’t make her compete in swim meets.
Elizabeth does not like swim meets. She gets horribly nervous because she is afraid that she will do something wrong and let everyone down. She started to talk about quitting swimming, which broke my heart because she loves swimming. So I came up with the deal.
Recently, Elizabeth’s team announced a T-shirt relay, which works like this: One person from each relay team puts on a T-shirt and a pair of socks and swims 50 meters. She takes off the clothes and put them on the next person, who then swims 50 meters. This continues until everyone on the team has completed a lap.
It wasn’t exactly a meet, because it would involve only team members. But Elizabeth thought it was. I told Elizabeth I really wanted her to go. She fought back angrily but finally agreed.
When the day for the T-shirt relay arrived, Elizabeth was nervous. She was chosen to swim the anchor leg (最后一棒).By the last leg, Elizabeth’s team had built up a narrow lead. Then it was Elizabeth’s turn to swim.
Approaching the halfway mark, she was still in the lead. Then somebody noticed that one of Elizabeth’s socks had fallen off and was floating in the pool. “She has to get that sock on before the end of the race,” a swimming official told Elizabeth’s team, “or you will be disqualified.”
Everybody on her team started shouting, “Elizabeth! Get the sock!” But she couldn’t hear them. Meanwhile, a girl in lane two was gaining on Elizabeth. Just then, a girl on my daughter’s team jumped in the pool, grabbed the sock, swam after Elizabeth and put the sock on Elizabeth.
With the sock finally on, Elizabeth swam her heart out for the last 15 meters and won! There was much celebration. And, for a few minutes, Elizabeth was the hero.
On the ride home, she relived her moment of glory again and again. She told me that if the T-shirt relay was an Olympic event, her team would win the gold medal, I told her that in my professional opinion, she was absolutely right.
