A new study says one part of the human brain may become smaller as a result of a condition known as jet lag．Jet lag results from flying long distances in an airplane．People with jet lag may feel extremely tired for several days．They may also have problems thinking clearly and remembering．
Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty young women who worked for international airlines．They had served passengers on airplanes for five years．These flight attendants flew across many countries and at least seven time zones．In the study, the flight attendants had different amounts of time to recover from jet lag．Half the women spent five days or fewer in their home areas between long flights．The other half spent more than fourteen days in their home areas．
The researcher took some saliva from the women's mouths to measure levels of a hormone (荷尔蒙) that increases during stress．He tested them to see if they could remember where black spots appeared on a computer screen．And he took pictures of their brains to measure the size of the brain's temporal lobes (脑叶)．
It was found that the women who had less time between flights had smaller right temporal lobes．This area of the brain deals with recognizing and remembering what is seen．The same group performed worse and had slower reaction times on the visual memory test．And their saliva samples showed higher levels of stress hormones．
The researcher believes the brain needs at least ten days to recover after a long trip．He says airline workers told him their ability to remember got worse after working on planes for about four years．Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory．
Scientists say more tests are needed to study the effects of jet lag on the brain．They want to find out if too much jet lag could permanently (永久性地) affect memory．

My first reaction was annoyance. It was Friday afternoon, and I was within an hour of finishing my work for the week. As I was leaving, a nurse brought me one more patient message. The statement read: “Mrs. Jones called to say that she has had blurred vision（视觉模糊）ever since her medical test this morning.”I smiled. Suddenly our tests were causing eye problems.
This week my patients had questioned everything. My patient with high blood pressure had stopped coming to her treatment on the advice of an Internet chat room. A woman who bad a mental problem was substituting（用……代替）St. John's word for her medication. Now Mrs. Jones was imagining problems. I rolled my eyes.
My second reaction was worry. As I looked through her record, I tried to figure out why she would have blurred vision, but nothing in her record explained the new problem. She's probably just anxious, I thought. Still, she wouldn't have called if she had been all right. I picked up the phone.
What I next felt can only be described as delight. Before I made the call, the nurse ran in: Mrs. Jones called. Her vision is fine. Turns out she picked up the wrong glasses when she left the office. The X-ray technician has been having the same problem. I let out a laugh. Mrs. Jones had been right. Her vision had been blurred. Now we know why.
Finally I felt shame. I came to realize what Mrs. Jones had taught me. I had first know she was wrong, that her anxiety had clouded her judgment. Instead, my medical training had clouded mine. Now I feel thankful that Mrs. Jones figured it out before I made a mistake about our relationship. Patients come to for my help. They pay me to listen, diagnose（诊断）, treat and talk. That suggests trust; I must remember that, and trust them too.
(1) The writer smiled while reading the patient message because he knew
[ ]
A．Mrs. Jones would ask for more tests
B．the patient was being unreasonable
C．the nurse was joking with him
D．Mrs. Jones would call him
(2) What has caused Mrs. Jones' eyes problem?
[ ]
A．Wrong glasses.
B．Medical checkup.
C．Her own imagination.
D．Chatting on the Internet.
(3) The underlined words“clouded her judgment”in the last paragraph probably mean
[ ]
A．made her less trustful toward the doctor
B．put her in control of her own feelings
C．made her less able to think clearly
D．put her in a dangerous situation

(A)
Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman’s shoe of a style popular in the 1890s. But what is unique(独特的) about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outface? Or did she throw away goods that she didn’t need in order to travel lighter?
Over 100, 000 people with “gold fever” made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildness. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.
The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks(背包) each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century.
1. The ordinary woman’s leather shoe is considered unusual because _______.
A. it was an important clue to life in the past B. it was found on a famous trail
C. it at one time belonged to a VIP D. it was a fashionable shoe at that time
2. According to this passage, many people who went to Alaska _______.
A. eventually became millionaires B. brought with them many shoes
C. had conflicts with the Eskimos D. were not properly equipped
3. The Canadian government made gold seekers bring one year’s supplies with them so that _______.
A. they would not die of hunger and cold
B. the army would have enough food for fighting a war
C. they would change these goods with the Eskimos
D. the supplies would make Alaska rich
4. No matter what happened to the woman who owned the shoe, _______.
A. she must have lived a happy life
B. she certainly dropped the shoe on purpose
C. her adventurous spirit is definitely admired
D. her other shoes were equally fashionable
(B)
Listen carefully, working people, we would like to tell you something that could save your precious time and money! Best of all, it is free!
It’s “no”.
What do you ask? We’ll say it again: “No”.
Sweet and simple “no”.
Say “no” at your office and see how quickly that pile of work on your desk disappears.
“Saying ‘no’ to others means you are saying ‘yes’ to yourself, ” said Leslie Charles, a professional speaker from East Lansing, Michigan.
“Time is precious. People are spending money buying time. And yet we are willing to give up our time because we can’t say ‘no’.”
Susie Watson, a famous writer, said people who always say “yes” need to say “no” without guilt(内疚)or fear of punishment. “I would rather have someone give me a loving ‘no’ than an obligated(强制的) ‘yes’, ” she said.
Susie Watson says she feels “no” obligation to give an explanation when she says “no” either socially or professionally. Does she feel guilty about it? “Not at all, ” said Watson, who is director of advertising and public relations at Timex Corp in Middlebury, Conneticut. “Most people are afraid of saying ‘no’… My advice is to say ‘yes’ only if you don’t mean ‘no’.”
Watson said “no” is the most effective weapon against wasting time. “Every year there are more demands on your time… Other people are happy to use up your time, ” Watson said. Time saving appears to be “no’s” greatest friend.
“No” can be your new friend, a powerful tool to take back your life. “No” may even take you further in the business world than “yes”.
“No” is power and strength. “No” now seems completely correct. “Saying ‘no’ isn’t easy. But finally it’s greatly liberating,” Charles said. But, he added, a “no” project needs to be worked on every day because it is hard to change long-term habit.
But, he also warns: “Don’t go to extremes. Don’t find yourself saying ‘no’ to everything. In return you should learn to hear ‘no’.”
5. The sentence “Saying ‘yes’ to yourself” means _______.
A. you can have more time to play with others
B. you needn’t care about other’s feeling if you are happy
C. you are selfish and treat others rudely
D. you can deal with your business as you have planned
6. When you say “no” to others you should say it in a _______.
A. secret way B. polite way
C. proud way D. guilty way
7. In Watson’s opinion, people can save much time on condition that _______.
A. they say “no” at a suitable time
B. they say “no” as much as possible
C. they are afraid of saying “no”
D. they make others angry at them
8. If a person says “no” to everything, the result he or she receive may be that he or she _______.
A. enjoys a wonderful life B. makes a lot of money
C. faces difficulty in life D. forgets to say “yes” in the end
(C)
A characteristic of American culture that has become almost a tradition is to respect the self-made man — the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.
This attitude toward manual(体力的) labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously (豪华地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional man may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.
9. From paragraph 1, we can know that in America _________.
A. people tend to have a high opinion of the self-made man
B. people can always rise to the top through their won efforts
C. college professors win great respect from common workers
D. people feel painful to mention their fathers as labors.
10. According to the passage, the hostess cooks dinner herself mainly because _________.
A. servants in American are hard to get
B. she takes pride in what she can do herself
C. she can hardly afford servants
D. It is easy to prepare a meal with canned food
11. The expression “ wait on table” in the second paragraph means “_________”.
A. work in a furniture shop B. keep accounts for a bar
C. wait to lay the table D. serve customers in a restaurant
12. Which of the following may serve as the best title of the passage?
A. A Respectable Self-made Family B. American Attitude toward Manual Labor
C. Characteristics of American Culture D. The Development of Manual Labor

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) 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.”
17. 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
18. 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
19. 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
20. 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
