Jim suffered heart problems.In conversation he expressed little joy and it seemed that his life was drawing to a close.

When his heart problems led to operation,Jim went through it successfully,and a full recovery was expected.Within days,however,his heart was not beating properly.Jim was rushed back to operation,but nothing was found to explain the cause of his illness.He died on the operating table on the day before his 48th birthday.

Dr.Bruce Smoller,a psychologist(心理学家),had had many conversations with him,and the more he learned,the stranger he realized Jim’s case was.When Jim was a child,his father,a teacher,suffered a heart attack and stayed home to recover.One morning Jim asked his father to look over his homework,promising to come home from school at noon to pick it up.His father agreed,but when Jim returned his father had died.Jim’s father was 48.

“I think all his life Jim believed he killed his father,”Dr. Smoller says.“He felt that if he had not asked him to look at his homework,his father would have lived.Jim had been troubled by the idea.The operation was the trial(判决) he had expected for forty years.”Smoller believes that Jim willed himself not to live to the age of 48.

Jim’s case shows the powerful role that attitude(态度) plays in physical health,and that childhood experiences produce far-reaching effect on the health of grown-ups.Although most cases are less direct than Jim’s,studies show that childhood events,besides genes,may well cause such midlife diseases as cancer,heart disease and mental illness.

Jim was sent back to operation because ______.

A.his heart didn’t work well

B.he expected a full recovery

C.his life was drawing to a close

D.the first one wasn’t well performed

What made Dr. Smoller feel strange about Jim’s case?

A.Jim died at a young age.

B.Jim died on the operating table.

C.Both Jim and his father died of the same disease.

D.Jim’s death is closely connected with his father’s.

From Smoller’s words,we can infer that ______.

A.Jim’s father cared little about his study

B.Smoller agreed that Jim did kill his father

C.Jim thought he would be punished some day

D.Smoller believed Jim wouldn’t live to the age of 48

Every baby born a decade from now will have its genetic code (基因编码) mapped at birth, the head of the worlds’ leading genome sequencing (基因图谱) company has predicted.

A complete DNA read – out for every newborn will be technically possible and affordable in less than five years, promising a revolution in healthcare, says Jay Flatley, the chief executive of Illumina. Only social and legal problems are likely to delay the age of “genome sequences,” or genetic profiles. By 2019 it will have become routine to map infants’ genes when they are born, Dr Flatly told The Times.

This will open a new approach to medicine, by which conditions such as high blood pressure and heart disease can be predicted and prevented and drugs used more safely and effectively.

A baby’s genome can be discovered at birth by a blood test. By examining a person’s genome, it is possible to identify raised risks of developing diseases such as cancers. Those at high risk can then he screened more regularly, or given drugs or dietary advice to lower their chances of becoming ill.

Personal genomes could also he used to ensure that patients get the medicine that is most likely to work for them and least likely to have side – effects.

The development, however, will raise legal concerns about privacy and access to individuals’ genetic records.

“Bad things can be done with the genome. It could predict something about someone – and you could possibly hand the information to their employer or their insurance company.” said Dr Flatley.

“People have to recognize that this horse is out of the barn, and that your genome probably can’t be protected, because everywhere you go you leave your genome behind. Complete genetic privacy, however, is unlikely to be possible”, he added.

As the benefits become clearer, however, he believes that most people will want their genomes read and interpreted. The risk is nothing compared with the gain.

In the first two paragraphs, the author mainly wants to tell us about .

A．the significant progress in medicine

B．the promise of a leading company

C．the information of babies’ genes

D．the research of medical scientists

Which of the following is a problem caused by this approach?

A．The delaying in discovering DNA.

B．The risk of developing diseases at birth.

C．The side – effects of medicine on patients.

D．The letting out of personal genetic information.

What does the underlined sentence “… this horse is out of the barn” mean?

A．Genetic mapping technique has been widely used.

B．Genetic mapping technique is too horrible to control.

C．People are eager to improve genetic mapping technique.

D．people can’t stop genetic mapping technique advancing.

What’s Dr Flatley’s attitude towards the technology?

A．Tolerant. B．Conservative. C．Positive. D．Doubtful.

Sitting in a dark movie theater with your friends. and a tub of popcorn (H^) sounds like a perfect way to spend a Saturday night, and it could be, if you are willing to share your popcorn with the entire row of moviegoers around you.
A review of movie-theater popcorn reveals an alarming amount of fat, salt and calories in even the smallest sizes. A large tub of popcorn at Regal Cinemas, for example, holds 20 cups of popcorn and has 1,200 calories, 980 milligrams of sodium (钠) and 60 grams of saturated (饱和的) fat. Adding just a tablespoon of butter adds 130 calories. And do not forget that it comes with free refills.
Not so hungry? The medium size popcorn, even the small, at 11 cups, delivers 670 calories, 550 milligrams of sodium .and 24 grams of saturated fat. The findings may surprise those who believe it is a relatively healthy snack. In fact, plain air-popped popcorn is low in calories and free of saturated fat. Movie theater popcorn, however, is popped in oil, often coconut oil, which is 90 percent saturated fat. Add salt to it, and your once-healthy snack turns into a health offender.
One way to make your popcorn healthier? Ask the theater to pop the corn without salt. The best way to make your movie snack healthier, however, would be to skip the popcorn.
"You could share a tub of popcorn with 10 friends," Dr. Nestle, a professor of nutrition at New York University, said. "Or, what a concept, watch the movie without eating anything."

66. Which kind of popcorn causes the least health concern?
A. Movie theatre popcorn.                                 B. Popcorn sold at Regal Cinemas.          C. Large size popcorn.                                      D. Plain air-popped popcorn.
67. What is Dr. Nestle's suggestion to moviegoers?

A young boy was sitting in the back seat of the car eating an apple. Hw asked his father, “Why does my apple turn brown?” His father answered,”“When the skin is removed, air reaches the flesh of the apple causes oxidarion. This changes the apple’s molecular structure and results in a brownish color.”The boy asked,“Dad，what are you

talking about?”

I know how that boy feels. Sometimes I want answers to some of those confusing questions that we all meet with, such as how to get through difficult times or what to do in a tough situation. I just want to get it right.

The problem is that I don’t always have the answer I need. Nobody else seems to have them, either. So I go on making mistakes and think that I’ll never get it right.

Often I didn’t know what to do. I often made poor choices, but I gradually improved. Then I realized that I don’t HAVE TO always get it right. I don’t have to always know what to do all the time. All I really need to do is try my best, learn from my mistakes and go on.

Dr. Leo Buscaglia once said, “ No one gets out of this world alive, so the time to live, learn, care, share, celebrate and love is now. That would be pretty hard to do when you’re waiting for all the answers first.”

So you got it wrong. You made a mistake. So what should you do next? Forgive yourself and try again. You may not get out of this world alive, but you can get plenty of life out of this world if you are not too worried about always getting it right.

With only about 1, 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species(物种). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.

Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”

The aim of “Noah’s Ark” project is to _______.

A. make efforts to clone the endangered pandas

B. save endangered animals from dying out

C. collect DNA of endangered animals to study

D. transfer the nuclear of one animal to another

According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.

A. available panda eggs B. host animals C. qualified researchers D. enough money

The best title for the passage may be _______.

A. China’s Success in Pandas Cloning

B. The First Cloned Panda in the World

C. Exploring the Possibility to Clone Pandas

D. China —the Native Place of Pandas Forever

From the passage we know that _______.

A. Kraemer and his team have succeeded in cloning a dog

B. scientists try to implant a panda’s egg into a rabbit

C. Kraemer will work with Chinese scientists in clone researches

D. about two thousand of species will probably die out in a century
