Autumn and winter are cold and flu seasons. Will the old advice about dressing warmly help prevent a cold, or if you get sick, should you follow the old saying, “feed a cold and starve a fever?” And what about that fever? Should you take medicine to reduce your temperature, or is it better to let the body treat the fever itself? Everyone seems to have an answer. But is popular wisdom valuable?
Doctor Nelson knows a lot about cold and flu seasons. Nelson says research may be just starting to provide proofs for long-held beliefs. For example, scientists for years were against the idea that getting cold and wet might cause colds or flu. But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses. So maybe it does make sense to wrap up warmly before going outside.
And what about feeding a cold and starving a fever? Nelson says if you have a cold and are hungry, you should eat. But a fever, especially a high one, suggests a more serious problem. He says people are usually not hungry when they have a high fever. Eating might even make a person sick. But drinking enough water is important. A fever easily makes the body lose water.
Finally, when should you treat a fever? Nelson says a fever should be treated if it stays at
40℃ or above for a day or more. A high temperature can damage brain cells. The doctor also believes in treating a fever if it prevents a person from sleeping.
Medicine like aspirin, for example, can be used to reduce pain and fever. But aspirin should not be given to children because it can cause serious problems.We can learn from the passage that Doctor Nelson________.
| A．doesn’t believe in the old advice about preventing colds |
| B．is now trying his best to provide proofs for long-held beliefs. |
| C．doesn’t think it necessary to see a doctor immediately if a person has a temperature of 40℃ |

According to Doctor Nelson, if someone catches a fever, he should________.
| A．bathe in cold water | B．drink enough water |
| C．try to eat something | D．take some exercise outside |
Which of the following is Not mentioned in the passage?
| A．When people should treat a fever |
| B．Whether the old advice about preventing a cold is valuable. |
| C．What the medicine , aspirin, is used for. |
| D．Why people should eat when having a cold. |
The passage suggests that_______.
| A．aspirin can damage train cells if an adult takes too much of it. |
| B．it is easier for people to catch colds when their bodies are stressed. |
| C．some old advice about preventing colds doesn’t make any sense. |
| D．the idea that getting cold can cause flu was proved true years ago. |
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.

3．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.
4．What’s Dr Flatley’s attitude towards the technology?

The Touchstone
When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book; and so a poor man, who could read little, bought it for very little money.
The book wasn't very interesting, but between its pages there was something very interesting indeed. It was a thin strip of vellum on which was written the secret of the "Touchstone"! The touchstone was a small pebble that could turn any common metal into pure gold.
The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles are cold.
So the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing pebbles. He knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone. Yet he went on and on this way. Pick up a pebble. Cold - throw it into the sea. Pick up another. Throw it into the sea. Pick up another. Throw it into the sea. The days continued over a long period if time.
One day, however, about mid-afternoon, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away.
So it is with opportunity. Unless we are cautious, it’s easy to fail to recognize an opportunity when it is in hand and it’s just as easy to throw it away.
1．The man bought the book because______.
A．he wanted to read it B．it was very interesting
C．there was a secret in the book D．he wanted to find the touchstone
2．We can learn from the passage that the touchstone is______.
A．pure B．cold C．magic D．big
3．Why did the man throw the pebbles into the sea?
A．Because he didn’t want to get the same pebbles.
B．Because he didn’t want others to pick them up.
C．Because he didn’t like their ordinary looks.
D．Because he didn’t like the cold feelings.
4．What does the author want to tell us in the passage?
A．We about orate opportunities in our life.
B．We should seek for opportunities in the world.
C．We may seize opportunities when we are watchful
D．We may discover opportunities when forming habits.
第三部分：阅读理解（共20小题，每题2分，满分40分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
Eight – year – old Jesse Abrogate was playing in the sea late one evening in July 2001 when a 7 – foot bull shark attacked him and tore off his arm. Jesse’s uncle jumped into the sea and dragged the boy to shore. The boy was not breathing. His aunt gave him mouth – to – mouth resuscitation (人工呼吸) while his uncle rang the emergency services. Pretty soon, a helicopter arrived and flew the boy to hospital. It was a much quicker journey than the journey by road.
Jesse’s uncle, Vance Folsenzier, ran back into to the sea and found the shark that had attacked his nephew. He picked the shark up and threw it onto the beach. A coastguard shot the fish four times and although this did not kill it, the shark’s jaws relaxed so that they could open them, and reach down into its stomach, and pull out the boy’s arm.
At the Baptist Hospital in Pensacola, Dr Ian Rogers spent eleven hours reattaching Jesse’s arm. “It was a complicated operation,” he said, “but we were lucky. If the arm hadn’t been recovered in time, we wouldn’t have been able to do the operation at all. What I mean is that if they hadn’t found the shark, well then we wouldn’t have had a chance.’
According to local park ranger Jack Tomosvic, shark attacks are not that common. “Jesse was just unlucky,” he says, “evening is the shark’s feeding time. And Jesse was in area without lifeguards. This would never have happened if he had been in area where swimming is allowed.’
When reporters asked Jesse’s uncle how he had had the courage to fight a shark, he replied, “I was mad and you do some strange things when you’re mad.”
1．What was the boy doing when the accident happened?
A．Feeding a hungry shark. B．Jumping into the rough sea.
C．Dragging a boy to the shore. D．Swimming in a dangerous area.
2．In which way did the boy’s uncle help with the operation?
A．By finding his lost arm. B．By shooting the fish.
C．By flying him to hospital. D．By blowing into his mouth.
3．How was his uncle in time of danger?
A．Careful. B．Brave. C．Optimistic. D．Patient.
Anyone who cares about what schools and colleges teach and how their students learn will be interested in the memoir（回忆录）of Ralph W. Tyler, who is one of the most famous men in American education.
Born in Chicago in 1902, brought up and schooled in Nebraska, the 19-year-old college graduate Ralph Tyler became hooked on teaching while teaching as a science teacher in South Dakota and changed his major from medicine to education.
Graduate work at the University of Chicago found him connected with honorable educators Charles Judd and W. W. Charters, whose ideas of teaching and testing had an effect on his later work. In 1927, he became a teacher of Ohio State University where he further developed a new method of testing.
Tyler became well-known nationality in 1938, when he carried his work with the Eight-Year Study from Ohio State University to the University of Chicago at the invitation of Robert Hutchins.
Tyler was the first director of the Center for Advanced Study in the Behavioral Sciences at Stanford, a position he held for fourteen years. There, he firmly believed that researchers should be free to seek an independent（独立的）spirit in their work.
Although Tyler officially retired in 1967, he never actually retired. He served on a long list of educational organizations in the United States and abroad. Even in his 80s he traveled across the country to advise teachers and management people on how to set objectives（目标）that develop the best teaching and learning within their schools.
1. Who are most probably interested in Ralph W. Tyler’s memoir?
A. Top managers. B. Language learners.
C. Serious educators. D. Science organizations.
2. The words “hooked on teaching” underlined in Paragraph 2 probably mean ________.
A. attracted to teaching B. tired of teaching
C. satisfied with teaching D. unhappy about teaching
3. Where did Tyler work as the leader of a research center for over 10 years?
A. The University of Chicago. B. Stanford University.
C. Ohio State University. D. Nebraska University.
Do’s and Don’ts in Whale(鲸) Watching
The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer. It is strongly recommended that vessel(船只) operators follow these guidelines for all kinds of whales.
· Approach whales from the side, not from the front or the back.
· Approach no closer than 100 metres, then stop the boat but keep the engine on.
· Keep noise levels down — no horns, whistles or racing of engines.
· Start your boat only after the whales are more than 100 metres from your vessel.
· Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.
· Approach and leave slowly, avoiding sudden changes in speed or direction.
· Avoid disturbing groups of resting whales.
· Keep at low speeds and remain in the same direction if traveling side by side with whales.
· When whales are traveling close to shore, avoid crowding them near the shore or coming between the whales and the shore.
· Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.
· If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.
· Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines.
