Directions: Read the following passage and choose the most suitable heading from A—F for each paragraph. There is one extra heading which you do not need．       
A．The results explained why time passes quickly when we are dealing with more tasks
B．Time flies when you are having fun and drags when you are bored．
C．Volunteers were told to finish three different tasks in the study．
D．There are areas of the brain having the function of estimating time．
E．Concentrating on time passing is probably a more accurate perception of reality
F．Focusing on' the duration or the color the of image makes trips speed．
【小题1】
Scans have shown that patterns of activity in the brain change depending on how we focus on a task． Concentrating on time passing, as we do when bored, will trigger brain activity which will make it seem as though the clock is ticking more slowly．
【小题2】
In the study, 12 volunteers watched an image while researchers monitored their brain activity using MRI scans．Volunteers were given a variety of tasks．In one they were told to concentrate simply on the duration of an image, in another they were asked to focus on the color, and in a third they were asked to concentrate on both duration and color．
【小题3】
The results showed that a network of brain regions was activated when more subjects were paid attention to duration．It is thought that if the brain is busy focusing on many aspects of a task, then it has to spread its resources thinly, and pays less heed（注意） to time passing．Therefore, time passes without us really noticing it, and seems to go quickly．
【小题4】
However, if the brain is not stimulated in this way, it concentrates its full energies on monitoring the passing of time．This may make time seem to drag, but in fact the researchers found that the more volunteers concentrated on the duration of the images, the more accurate were their estimates of its duration．
【小题5】
Lead researcher Dr Jennifer Coull said many of the areas of the brain involved in estimating time were the same that played a key role in controlling movement, and preparing for action．She said this overlap suggests that the brain may make sense of time as intervals between movements, in much the same way as a musician marks time with his foot, or an athlete anticipates the sound of a starter's pistol（手枪）．

Bamboo is one of the nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.

Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains.

Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.

Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.

In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills can help to make the poor thirsty fields to be watered.

One silly question I simply can’t stand is “How do you feel?” Usually the question is asked of a man in action—a man on the go, walking along the streets, or busily working at his desk. So what do you expect him to say? He’ll probably say, “Fine, I’m all right,” but you have put a bug  in his ear—maybe now he’s not sure. If you are a good friend, you may have seen something in his face, or his walk, that he overlooked(忽略) that morning. It starts worrying him a little. First thing you know, he looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else “How do you feel?” Every question has its time and place. It’s perfectly acceptable, for instance, to ask “How do you feel?” if you’re visiting a close friend in the hospital. But if the fellow is walking on both legs, hurrying to take a train, or sitting at his desk working, it’s silly to ask him that silly question. When George Bernard Shaw, the famous writer of plays, was in his eighties, someone asked him. “How do you feel?” Shaw put him in his place. “When you reach my age”, he said, “either you feel all right or you’re dead.”

It is reported that six Chinese ships have entered waters near islands claimed by both China and Japan. China said the ships were carrying out “law enforcement” to demonstrate its jurisdiction(管辖权) over the islands, known as Diaoyu in China and Senkaku in Japan. At least two of the ships left after the Japanese coast guard issued a warning, Japanese officials say.
The action came after Japan sealed a deal to buy three of the islands from their private Japanese owner. Japan controls the uninhabited but resource-rich East China Sea islands, which are also claimed by Taiwan.
The Japanese Coast Guard said the first two Chinese boats entered Japan’s territorial waters at 06:18 local time, followed by another fleet of four other ships just after 07:00. The first two ships then left the area. A third ship left later on Friday morning, one report said. No force was used, Japanese officials added. “Our patrol(巡逻) ships are currently telling them to leave our country’s territorial waters,” the coastguard said in a statement.
The Chinese foreign ministry confirmed that its ships were there. “These law enforcement and patrol activities are aimed to demonstrate China’s jurisdiction over the Diaoyu Islands and ensure the country’s maritime interests,” a statement said.
The US has called for “cooler heads to be accepted” as tension worsens between China and Japan over the islands. US Defense Secretary Leon Panetta is going to visit both Japan and China from this weekend as part of a tour of the region.
The dispute(争端) has seriously damaged diplomatic relations between China and Japan and threatens to damage the strong trading relationship, says the BBC’s John Sudworth in Beijing. The dispute has also caused strong nationalist emotions on both sides that makes it very difficult to be seen to be backing down, says our reporter.
The Japanese government says it is buying the islands to promote their stable and peaceful management. China on the other hand, says the islands have historically been its territory and fishing grounds. Meanwhile Japan’s newly-appointed ambassador to China, Shinichi Nishimiya, remains in hospital in Tokyo. He was appointed on Tuesday to replace Uichiro Niwa, who has been criticized for his dealing with the worst diplomatic dispute between Japan and China in recent years.
【小题1】The Diaoyu Islands are actually inhabited(居住) by              .

They like using the Internet. They have lots of pocket money to spend. And they spend a higher proportion of it online than the rest of us. Teenagers are just the sort of people an online seller is interested in, and the things they want to buy----games, CDs and clothing----are easily sold on the Web.

But paying online is a tricky business for consumers who are too young to own credit(信用) cards. Most have to use a parent’s card. They want a facility that allows them to spend money.

That may come sooner than they think: new ways to take pocket money into cyber (网络的) space are coming out rapidly on both sides of the Atlantic. If successful, these products can stimulate(刺激) online sales.

In general, teenagers spend huge amounts: $153bn (billion) in the US last year and ￡20bn annually in the UK. Most teenagers have access to the Internet at home or at school－88 percent in the US, 69 percent in the UK. According to the Jupiter Research, one in eight of those with Internet access has bought something online－mainly CDs and books.

In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children. Pressing parents to spend online is less productive than pressing on the high street. They are more likely to ask “Why?” if you ask to spend some money online.

One way to help teenagers change notes and coins into cybercash is through prepaid cards such as InternetCash in the US and Smart cards in the UK. Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as￡20 or $50 with a hidden 14-digit number that can be used to load the cash into an online account.

1.What does the word “They” in paragraph 1 refer to?

A．Sellers.           B．Buyers.           C．Teenagers.         D．Parents.

A．More than half of the teenagers in the US and the UK have Internet access.

B．Teenagers pay for goods online with their own credit cards.

C．Most teenagers in the US and the UK have bought something online.

D．Teenagers found it easier to persuade parents to buy online than in a shop.

3.A new way to help teenagers shop online is to use ______.

A．a new machine     B．prepaid cards      C．special coins and notes    D．pay-as-you-go mobile phones

4.What is the passage mainly about?
