We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it’s hard not to wonder if the disease that comes from foreign animals is homing in on human beings. “Most of the infections (感染) we think of as human infections started in other animals, ” says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University.
It’s not just that we’re going to where the animals are, we’re also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen’s pets, and she now thinks that keeping foreign pets is a bad idea. “I don’t think it’s fair to have them as pets when we have such a limited knowledge of them,” says Isaksen.
“Laws allowing these animals to be brought in from deep forest areas without stricter control need changing,” says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But some strains (变异体) may become harmful. Monkey-pox doesn’t look a major infectious disease. But it is not impossible to pass the disease from person to person.

D．We do not know much about them yet
3．What does the phrase “the wake-up call” in paragraph 3 most probably mean?
A．a new disease
B．a clear warning
C．a dangerous animal
D．a morning call
4．The text suggests that in the future we____________.
A. may have to fight against more new diseases
B. may easily get infected by diseases from dogs

Malnutrition (营养失调)remains a serious problem for India. But a new study shows that India’s leading causes of death now also include diseases related to obesity（肥胖）such as heart disease.
India’s National Family Health Survey shows that more than twenty percent of Indians living in cities are overweight or obese. And in the northwestern state of Punjab, that is true for almost forty percent of women.
Aradhna Tripathi is a business professional in New Delhi. She said, “ Eating is the most important thing in any Indian household and how you show your love and gratitude(感激) for a person is through the kind of food you serve him. And the kind of lifestyle we are leading is one of the reasons why we have the number of obese people increasing every day.
But Aradhna Tripathi says she has decided to lose weight. Her mother and grandmother are also diabetic(患糖尿病的). In fact, the International Diabetes Federation says India is now the diabetes capital of the world. Researchers say Indians store more body fat per kilogram than Europeans. That means obese Indians are even more at the risk of diabetes than other people.
Doctor Anoop Misra at Fortis Hospital in New Delhi says the risk of diabetes is crossing social and economic lines. Five years ago, he says, obesity and diabetes were limited to India’s richest people, but now things have changed.
But Doctor Misra is hopeful that the spread (蔓延，传播)of obesity can be slowed. And he says it must start in schools by giving all Indian children the same instruction on physical activity and diet.
The World Health Organization says China is also moving up in obesity rates. The estimate (估计) has reached about five percent countryside and as high as twenty percent in some cities.What is this passage mainly about?
| A．Obesity has become a big killer in India. |
| B．Heart disease is troubling people in India. |

| A．.the development of economy |
| B．the change of Indians’ lifestyle |
| C．Indians’ attitude （态度）towards eating |
| D．Indians’ attitude towards obesity. |
What can we infer from the underlined sentence in Paragraph 5?
| A．Most rich people in India are overweight. |
| B．Five years ago, few people in India were overweight |
| C．Few poor people are diabetic for economic reasons. |
| D．Now even the poor in India suffer from obesity. |
Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later.
I am one of those unlucky people who have poor sense of direction and I may have visited a place time after time but I still get lost on my way there. When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hope that by some chance I would get to the place I was heading for.
I am no longer too shy to ask people for direction, but I often receive replies that puzzle me. Often people do not like to admit（承认）that they didn’t know their hometown and will insist on telling you the way, even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you can not possibly hope to remember, and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite（相反的）direction to that in which you should be going.
If anyone ever asks me the way to somewhere, I always tell them I am a stranger to the town in order to avoid giving them wrong direction but even this can have embarrassing results.
Once I was on my way to work when I was stopped by a man who asked me if I would direct him the way to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building. However, at this point, I decide it was too late to turn back and search for him out of the crowd behind me as I was going to meet with someone at the office and I did not want to keep him waiting.
Imagine my embarrassment when my secretary showed in the very man who had asked for directions of my office and his astonishment when he recognized me as the person he had asked.What is the writer going to do when someone asks him for direction?
| A．He will direct the right way to the person willingly. |
B．He will reply to it by the means of being a stranger to the town. |
C．He will give the very person long list of direction. |
D．He is going to show the man an opposite direction. |
Why did the writer consider himself to be an unlucky dog?
| A．Because of his poor sense of direction. |
| B．Because he always forget the way to home. |
| C．Because he did not have any friend. |
| D． Because he used to be shy and dared not ask others the way. |
How did the visitor feel when he was showed into the very room?
| A．He felt strange. | B．He felt embarrassed. |
| C．He felt very sad. | D．He felt astonished. |
Who showed the right way to the interviewee according to the passage?
| A．Someone we don’t know. | B．The writer did it for himself. |
C．The secretary did so. | D．A warm-hearted old lady did itI. |
Personal computers and the Internet give people new choices about how to spend their time.
Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.
E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she’d been born before electronic mail became such a practical tool.
The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun - see a great movie perhaps - and there are four or five friends who might want to hear about it. If you call each one, you may be tired of telling the story.
With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.
E-mail is also an inexpensive way stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.
We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don’t take the place of any of the old ways. The purpose of this passage is to ________.
| A．explain how to use the Internet |
| B．describe the writer’s joy of keeping up with the latest technology |
| C．tell the merits(价值) and usefulness of the Internet |
| D．introduce the reader to basic knowledge about personal computers and the Internet |
The use of E-mail has made it possible for the writer to ________.
| A．have more free time with his child | B．spend less time working |
| C．work at home on weekends | D．work at a speed comfortable to him |
According to the writer, E-mail has an obvious advantage over the telephone because the
former helps one ________.
| A．reach a group of people at one time conveniently |
| B．keep one’s communication as personal as possible |
| C．pass on much more information than the later |
| D．get in touch with one’s friends faster than the later |
The best title for this passage is ________.
| A．Computer: New Technological Advances |

Everybody may have seen the film “Death on the Nile ( 尼罗河)”, but nobody can imagine that the writer of the story, Agatha Christie, saved a baby in a most unusual way.
In June 1977, a baby girl became seriously ill in Deleville. Doctors there were unable to find out the cause of her illness, so she was sent to a famous hospital in London, where there were many excellent doctors. The baby was so seriously ill that a team of doctors hurried to examine her without delay. The doctors, too, were puzzled by the baby’s illness and they also became discouraged. Just then a nurse asked to speak to them.
“I think the baby is suffering from thallium (铊) poisoning. ” said the nurse. “A few days ago, I read a story ‘A Pale Horse’ written by Agatha Christie. Someone uses thallium poison, and all the symptoms (症状) are written in the book. They are exactly the same as the baby’s.”
“You’re very good at observing things,” said a doctor, “and you may be right. We’ll carry out some tests and find out whether the cause is thallium poisoning or not.”
The tests proved that the baby had indeed been poisoned by thallium. Once they knew the cause, the doctors were able to give her correct treatment. The baby soon got well and was sent back to Deleville. A week later it was reported that the poison might have come from an insecticide (杀虫剂) used in Deleville.

Joseph Goldberger was a doctor for the Unite States Public Health Service. In 1912, he began to study a disease that was killing thousands of people in the South. The disease was pellagra(烟酸缺乏病).
Doctor Goldberger traveled to the state of Mississippi where many people had pellagra. He studied the patients and their families. Most of the people were poor. The doctor came to believe that the disease was not passed from one person to another, but instead had something to do with food.
He received agreement from state officials to test this idea at a prison(监狱). Prisoners were offered pardons if they took part. One group of prisoners received their usual food, mostly corn. A second group ate meat, fresh vegetables and milk. Members of the first group developed pellagra. The second group did not.
But some experts refused to accept that poor food caused pellagra. They thought there were other causes.
So Doctor Goldberger put blood(血液) from a person with pellagra into his own body. He even took pills that had blood from pellagra patients. An assistant also took part in the experiments. So did Doctor Goldberger’s wife. None of them got sick. Later, the doctor discovered that a bit of dried brewer’s yeast(酿酒的酵母) each day could prevent pellagra.
