　　In 1954 a turning point in medical history, resulting from applied bionics; was the first “open heart” surgery done in Minneapolis, Minnesota, by Dr. W. Lillehei's techniques for the first time allowed the patient to be operated on while blood was supplied to the patient from a donor. Today “open heart” surgery, using more complicated methods and bionic devices, is common in the United States.

　　Important technological advances such as those already mentioned have encouraged scientists to develop the artificial heart. Early in 1983, in its first use by a human patient, a medical team at the University of Utah Medical Center replaced the diseased heart by a Jarvik-7.

　　The world watched amazed as television pictures of Dr. Clark showed him as he improved steadily after the surgery. His continued life demonstrated, that a bionic device could imitate the action and function of a healthy heart. Dr. Clark lived for 112 days.

　　Life-like or bionic machines have existed for several centuries. The development of tools by man's ancestors is a good example of the application of bionics to extend human capabilities. Modern bionic research is especially involved in prosthetics devices that substitute for, or replace lost or diseased body parts such as arms, legs, and eyes.

　　Recent advances in electronics have enabled scientists to make better use of electrical impulses in the control of prosthetic devices. One interesting research project is the development of an artificial eye in which video signals are transformed into fight patterns that are sent into nerve receptors in the patient.

　　The future for applied bionics seems to be promising. Existing bionic devices will become smaller, faster, and more effective. The artificial heart used for Dr. Clark is only one of experimental replacement devices. It is likely to be joined in the future by replacements for other internal systems or organs.

　　Bionic livers, stomachs, and lungs are not impossibilities!

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.

1. The biggest difficulty in operating on the damaged brain is that_____.

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 w*w

2. The brain operation was made possible mainly by        .

A. taking the blood out of the brain         B. trying the operation on monkeys first

C. having the blood go through a machine      D. lowering the brain’s temperature

3. With Dr. White’s new idea, the operation on the damaged brain        .

A. can last as long as 30 minutes    B. can keep the brain’s blood warm

C. can keep the patient’s brain healthy  D. can help monkeys do different jobs

4. What is the right order of the steps in the operations?

A. send the cooled back to the brain       B. stop the blood to the brain

C. have the blood cooled down        D. operate on the brain

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

5. Which of the following is not true?

A. If there isn’t enough blood, the brain can live for only three to five minutes.

B. If the brain is very cold, it can live without blood for half an hour.

C. Dr. White tried his idea for thirteen times.

D. After their operations, the monkeys were healthy and busy again

New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.

Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.

The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.

Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.

“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”

But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.

The study has raised new questions about “body mass index,”（体重指数） or BMI. This is a measurement of body fat as a ratio（比率） of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.

Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.

Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes（糖尿病）.

1.According to the new findings, the researchers found that __________ .

A.People with high obesity have a lower risk of early death than people with low obesity

B.People with overweight have a greater risk of early death than people of normal weight.

C.People with mild obesity are less likely to die than people of normal weight.

D.People with obesity live much longer than people of normal weight.

2.What does the underlined word “literature” in paragraph 6 mean ?

A.works like novels and poems

B.books and articles on a particular subject

C.printed material

D.magazines and newspapers

3.Which of the following statements is not true according to the passage?

A. BMI is commonly used to measure body fat as a ratio of height to weight.

B. Not all people with a little higher BMI are fat .

C. Many public health experts encourage more people to use BMI as a way to predict the risk of health problem

D. Because of the ne w findings, people should think about gaining extra weight.

Picture this situation. It is late afternoon and you are    36   . You have an important dinner engagement that evening so you    37    to take an hour nap. Instead of setting your alarm you ask a friend who is visiting to wake you in an hour. He   38    .
Two hours later, your friend wakes you. You ask, “Why didn’t you wake me after one hour?” He    39    that he thought you asked him to wake you in two hours and that is what he said. You then have to run around and get ready    40  , muttering to yourself about how you    41   have set the alarm rather than asking your friend to wake you. Had you done that, you would not have been so    42    to get ready.
Your conclusion is correct. Your    43   of what happened looked at the system you used. Your friend’s  44   to wake you resulted from a miscommunication.   45   he didn’t hear you correctly or you misspoke.
46   at the situation from the point of view of being personally responsible is always better than blaming yourself or another. So how do you best be “responsible” in this situation? The answer is   47   in systems thinking.
Dr. W. Edward Deming is the American statistician who is credited with   48   the quality practices to Japan.   49   his arrival in that country in 1950, the label “made in Japan” was synonymous with inferior(劣等的) quality. Now the same “made in Japan” label is synonymous(等同) with   50   quality.
So what did Dr. Deming teach the Japanese that made such a  51   to the quality of their products? The answer is quite simple, yet profound.   52   on years of statistical analysis, Deming was able to validate(证明) that 94 % of all failures are not because people don’t want to do a good job. The fact is that   53   people want to do a good job.
What, then, is the   54   if it’s not the people?
It’s the system. The system failed in 94% of the    55   , not the people.
