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(矛盾的)’,” 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 (视觉) is a relatively recent addition to our line of mammals(脯乳动物)
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.

Bicycles are a great way to get around. They are fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike – make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.

This year’s Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, had three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.

Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country’s economic troubles.

“I see a problem in my country,” Renato said, “If you go to the forests in Peru, in some places you can not find electricity. If you go with my bicycle, you can turn on the lights.”

Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender fastened to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.

The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country road. It’s made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.

“You pedal the bike, and you can mix any drink you want,” Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

1. What can we learn from the first paragraph?

A. Bicycles are the best way to go about.

B. Bikes should be made more comfortable to ride

C. You can improve your bicycle for science research.

D. Many inventions are connected with the bicycle.

2. Which of the following is true according to the passage?

A. ISEF is an exhibition displaying bicycle experiments designed by students.

B. Looking closely at things you are concerned about can lead to scientific research

C. Renato’s improvement of the bicycle has solved the country’s great problem.

D. Renato’s special bicycle will soon be put into use in remote areas.

3. The underlined word “address” in the third paragraph probably has the same meaning as _______.

A. make address written                   B. give up    C. work at    D. speak at

4. Renato’s special Multibike has all the following functions except ______.

A. making knives sharp

B. mixing any kind of drinks

C. producing electricity

D. operating a machine with its own electricity

5. It can be inferred that Renato’s special bicycle is mainly designed for ______.

A. distant areas in the rainforest without electricity

B. the use of his own family to make life easier

C. the competition of ISEF to win money to support remote rainforests

D. enough exercise by pedaling it.

On the snowy Tibet plateau, traditional elements have been mingled with modern life -- youths dressed in the latest fashion dancing "Guozhuang," office-ladies playing conventional Tibetan music while driving to work and Tibetan girls wearing superb folk costume displaying their nice figures.

"I used to go shopping or bar-hopping with my friends after work. But now I don't think it is advisable to continue following that living style," said Pasang, a young Tibetan girl who practices Yoga everyday at a fitness club in the eastern suburbs of Lhasa city.

Today, the conception to live in a healthy way has become more popular in Tibet's general public.

When the night falls, crowds of aged citizens dancing "Guozhuang," a traditional Tibetan group dance, to vigorous folk music can be seen in many residential communities. Among them, Pasang's mother Tseden Wangmo, 63, is undoubtedly one of the enthusiasts in such an outdoor team activity: "I like dancing Guozhuang very much, for it can make my body strong, bring me good mood and carry forward Tibetan ethnic culture as well."

Different from their elder generations, a swarm of teenagers play skateboard or roller-skating shuttle among groups of strollers on the squares in front of the Potala Palace and Norbulingka, the Dalai Lama's permanent residence.

The stylish dress, colored hairs, an earring on a single ear or an obscure tattoo -- all these signals have highlighted Tibet's younger generation's personality and their view on fashion.

Lhakpa Tashi, 16, will become a high-school student in the second half year. This adolescent is a typical fan at various kinds of modern novelties, such as surfing the net, online shopping and foreign Rap music.

Are you a problem shopper? The answer is “Yes”, if you or someone else thinks that you sometimes get carried away with shopping. In other words, do you or does someone else think you are occupied in extreme shopping? If people have regrets later about their shopping, or have an “out-of-control” feeling about the quantities of what they buy or the amount of credit they use, they may be considered to be problem shoppers. 

Extreme shopping can lead to a more serious problem — addictive shopping. Addictive shoppers feel driven by the desire to shop and spend money. They experience great tension which drives them to shop and spend money and they feel a “rush” during the time they are occupied with the shopping activity.

Extreme or addictive shopping may result from long-time unpleasant feelings, of which anxiety, pain and shame are common ones. When we feel bad inside, we often do something to make ourselves feel better. In this case, we often go shopping.

A few people shop to relieve their boredom or emptiness. For some people, the motivation is a desire for status, power, beauty or success. Some love to shop as it makes them feel valued in the eyes of the shop assistants. Others shop simply because it makes them forget, at least temporarily, tension, fear or unhappiness in their life.

Besides, shopping malls are designed to encourage continual shopping. For instance, there are some malls where you can’t see clocks displaying the time because they don’t want you to become too aware of the time you spend there. What’s more, food courts, coffee shops and restrooms are provided, so you don’t have to leave the mall because of your physical needs.

Therefore, once you become aware of how market forces work, you will certainly come to control your shopping behavior. For example, how much time you will spend and what areas you will visit can be decided before you enter the mall. Keep a written account of what items you will buy and how much money you will spend. Make a plan for what you are going to buy before you feel the urge to shop and then stick to it. That is vital for gaining self-control.

1.Which of the following people may not be problem shoppers?

A. Those who cannot control the amount of credit they use.

B. Those who just walk around the shopping malls.

C. Those who are occupied in too much shopping.

D. Those who feel sorry for their shopping.

2.According to the passage, what may not result in addictive shopping?

A. The awareness of how market forces work.

B. The desire for status, power, beauty or success.

C. Boredom, emptiness, tension, fear or unhappiness in people’s life.

D. Long-time bad feelings of anxiety, pain and shame.

3.What does the author suggest to control our shopping behaviour?

A. Never going to the shopping malls because there are many tricks.

B. Applying for a credit card before we go shopping.

C. Making the shopping time as short as possible. D. Making a shopping list before we go shopping.

4.The author writes this passage to _______.

A. inform the shopping malls how to attract more shoppers

B. provide solutions to the problem shopping

C. scold the problem shoppers        

 D. tell a shopping story
