Anyone who ever wondered why a dying plant, say, a freshly-cut red rose may appeal to a lady friend, might take some comfort in science, which once again offers us a reasonable answer to one of the world’ s great mysteries.
Beyond a common preference in people for blue, “the long history of color preference studies has been described as ‘confusing and contradictory,” write scientists Anya Hurlbert and Yazhu Ling of England’ s Newcastle University, authors of a new study in the journal Current Biology. “This fact is perhaps surprising,” they said, “though the popularity of the concept that little girls differ from boys in preferring pink.”.
But the scientists believe they have an answer to this scientific mystery, discovering women’s preference for red, hidden above the average liking for blue.
In their study, the pair quickly flashed color cards, displaying many different aspects, at 208 volunteers, mostly Britishers but with a number of Han Chinese, who moved to the United Kingdom recently. Tested in three different experiments, the researchers found out a small but significant preference for reddish colors in the female volunteers.
Puzzled, the authors realized that most of the difference between men and women came in the form of a preference for green VS red in the color cards, regardless of the other slight differences such as the slightly blue ones that everyone liked. Why might this be?
Evolution might offer an answer, they reason. Human color perception（感知）, the assessment of three separate color types-red-green-blue-in our vision is a relatively recent addition to our line of mammals.
Adding weight to their argument, they found the women who are most typically feminine（女性的）on a psychological survey also had the biggest preference for reddish colors. “My love is like a red, red rose,” wrote the Scottish poet Rober Burns in 1794.The scientists discovered the colour mystery that exists between men and women by _____..

| C．stating causes and effects | D．interviewing volunteers. |
The word “pair” in Para.4 refers to _____.
| A．man and woman | B．science and evolution . |
| C．Anya Hurlbert and Yazhu Ling | D．red and green |
According to the study the scientists have carried out in the passage, _____.
| A．men like blue most. |
| B．women have preference for red besides blue. |
| C．generally speaking boys prefer slight pink to blue. |
| D．girls also love slight green. |
It was a dark and cold night. The car driver didn’t have even one passenger all day. When he went by the railway station, he saw a young man coming out with two bags in his hands. So he quickly opened the door of the car and asked, “Where do you want to go, sir?”
“To the Star Hotel,” the young man answered. When the car driver heard that, he didn’t feel happy. The young man would give him only three dollars because the hotel was not far from the railway station. But suddenly, he had an idea. He took the passenger through many streets of the big city.
After a long time, the car finally arrived at the hotel. “You should pay me fifteen dollars,” the car driver said to the young man. “What! Fifteen dollars? Do you think I’m a fool? Only last week I took a car from the railway station to this same hotel and I only gave the driver thirteen dollars. I know how much I have to pay for the trip. I won’t pay you one dollar more than I paid to the other car driver last week.”Which of the following is true?____________

A healthy dose of sunshine may be the secret to staying young, British scientists have disclosed.
Vitamin D is produced naturally by the skin in response to sunlight and may help to slow the ageing process and protect against heart disease, according to the study.
Researchers from King's College London studied 2,160 women a
ged between 18 and 79, looking at their telomeres - a biological marker of ageing found in DNA．As people get older, their telomeres get shorter and they are easy to have illnesses.
But the study found women with high levels of vitamin D had comparatively longer telomeres - a sign of being biologically younger and healthier.
The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.
Lead researcher Dr Brent Richards said: "These results are exciting because they prove for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D．
"This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer."
He said further studies are required to confirm the findings.
Professor Tim Spector, head of KCL's twin research unit, and a co-author of the report, added: "Although it might sound absurd(荒谬的), it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process."
Vitamin D made by the action of sunlight on the skin accounts for 90 per cent of the body's supply, but lower levels can also be obtained through food such as fish, eggs and breakfast cereals.
Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.What’s the best title of this passage?

Every once in a while, it is necessary to take a step back in order to take a long, hard look at where we are in our lives. At this point, it is good to ask yourself a bunch of critical questions. Are you at the point in your career where you want to be ? Have you so far accomplished all o
f your goals in life ? If so, then maybe it is time to make goals that stretch yourself a bit more. If you have not accomplished your goals in life, then perhaps you have made the mistake of setting too many goals or trying to accomplish them at an unnaturally fast pace.
It is necessary to set reasonable, intelligent goals in order to succeed in life. Do not be unrealistic because life is not a fairy tale. But you should try to recognize what you want, and to be as specific as possible when attempting to visualize（形象化） or otherwise express what your goals in life are.
In order for a goal to sufficiently motivate you, it needs to be a major one. The bigger your goals are, then the more motivated you will need to be to work towards accomplishing them. If you want, for example, to be the greatest concert pianist, in the world, then you are going to find yourself a lot more motivated than you would be if your goal were merely to, say, play a couple of Beethoven pieces extremely well. If you are a beginner, then no doubt mastering those tough songs is a very intelligent and realistic goal to set. But if that is your only goal as a pianist, then you will stop growing as a pianist once that goal has been achieved. This is why it is necessary to constantly stop and re-evaluate our goals so that we are aware of what they are, and thus stay motivated.From the passage, if your goals have all been achieved, you should then ______.
| A．ask yourself some serious questions |
| B．take a hard look at your success |
| C．set some other intelligent goals |
| D．stretch yourself to relax |
By saying “life is not a fairy tale”, the author suggests that you should ________ .
| A．set as big a goal as possible |
| B．try hard to realize your dream |
| C．make your goals practical |
| D．abandon all your ambitions |
To perform several Beethoven pieces well is a goal that __
_____.
| A．is not suitable for the pianist |
| B．is appropriate for a beginner |
| C．stops you from growing as a pianist |
| D．is very easy to achieve |
What is the best title for the passage ?
| A．Set Intelligent Goals for Yourself |
| B．Try to Accomplish Your Goals |
| C．Get Yourself More Motivated |
| D．Goals Help You to Succeed |
The United Nations Children’s Fund (UNICEF) has declared October 15 as Global Handwashing Day in 2005．The first Global Handwashing Day is on October 15 of 2008.Activities are planned over twenty countries to get millions of people in the developing world to wash their hands with soap. Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the UN Children's Fund, American government agencies, the World Bank and soap makers Unilever and Procter and Gamble. The goal is to create a culture of hand washing with soap.
Hand washing can prevent the spread of disease. Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.
When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth
. Then they can infect others.
The organizers say all soaps are equally effective at removing disease-causing germs. The correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds.Then, rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air. Soap is important because it increases the time that people spend washing. It also helps to break up the grease and dirt that hold most of the germs.And it usually leaves a pleasant smell,which increases the likelihood that people will wash again.
Washing with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea(痢疾) by almost half. And it could reduce deaths from pneumonia and ot
her breathing infections by one-fourth. Diarrhea is the second leading cause of child deaths, killing more than one 
and a half million children a year. Pneumonia is the leading cause, killing about two million children under five each year. Hand washing can also prevent the spread of other diseases.We can learn from Paragraph 1 that _______.
| A．the first Global Handwashing Day was held in 2005 |
| B．many originations support the idea of Global Handwashing Day |
| C．Global Handwashing Day was founded by many soap makers |
| D．the content of Global Handwashing Day is to wash your hand frequently |
The underlined phrase “critical moments” in Paragraph 2 refers to _______.
| A．the important occasions |
| B．schedules |
| C．the arrangement of a time |
| D．the necessary parts in health |
The main purpose of the story is to tell us ________.
| A．hand washing is very important |
| B．to create a culture of hand washing with soap |
| C．germs can infect ourselves and others |
| D．soaps play an important role in everyday life |
The last paragraph implies that ___________.
| A．a soap is a kind of medicine to prevent a disease |
| B．it is important for children to wash hands in a correct way |
| C．Pneumonia kills about two million children each year |
| D．Diarrhea is the second leading cause of child deaths. |
As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through lift, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stre
ss gets out of
control that it can lead to poor performance
and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "figh
t" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress is, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.People are finding less and less time for relaxing themselves because_____.
| A．they do not know how to enjoy themselves |
| B．they do not believe that relaxation is important for health |
| C．they are travelling fast all the time |
| D．they are becoming busier with their work |
According to
the writer, the most important character for a good manager is his ________.
| A．not fearing stress | B．knowing the art of relaxation |
| C．high sense of responsibility | D．h aving control over performance |
Which of the following statements is true?
| A．We can find some ways to avoid stress. |
| B．Stress is always harmful to people. |
| C．It is easy to change the habit of keeping oneself busy with work. |
| D．Different people can withstand different amounts of stress. |
In the last sentence of the passage, "do so " refers to ______.
| A．"expose ourselves to stress" |
| B．"find ways to deal with stress" |
| C．"remove stress from our lives" |
| D．"established links between diseases and stress" |
