Research shows that humans switch from selfish to unselfish behaviour when they are watched．Do you?
A picture of a set of eyes on a computer screen can cause a change in the way people act．Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box．
Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behaviour．Their report also referred to other research showing that this response of behaving well when watched is somehow coded into humans and people respond this way unconsciously, or without realizing it．
It is not just humans that act unselfishly when they are being watched．A fish called the grooming fish cleans other fish．When other fish are around, it is gentler．When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning．
The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched．This could be the reason for the success of a famous American army poster．On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster．Under the picture was the caption 'I Want You' It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese．

Some teens believe drugs will help them think better, and be more popular. These days, drugs can be found everywhere. Many teens are tempted(诱惑) by the excitement or escape from reality that drugs seem to offer.
Drugs are chemicals that change the way our bodies work. When you put them into your body, drugs find their way in your blood and are taken to parts of your body, such as your brain.
The effects of drugs can be different depending on the kind of drug taken, how much is taken, how often it is used, how quickly it gets to the brain, and what other drugs or food are taken at the same time. Although drugs can make you feel good at first, they can finally do a lot of harm to the body.
There are many kinds of drugs available, and there are many reasons for trying them regularly. People take drugs just for pleasure they believe they can bring. Often it’s because someone told them that drugs would make them feel good or that they’d have a better time if they took them.
Many teens use drugs because they’re unhappy or think drugs will help them escape their problems. The truth is that drugs don’t solve problems—they simply hide feelings and problems. When a drug wears off, the feelings and problems remain, or became worse. Drugs can ruin every aspect of a person’s life.The main idea of the second paragraph is probably _________.

Laptop（便携式电脑） computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a ＄10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak ” with their teachers, their classmates, and their families. however, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees----anywhere at all!
Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable （手提式）computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.
At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “Here we are in the middle of Virginia and were giving students a window on the world. They can see everything and do everything.

Malaria, the world's most widespread parasitic (寄生虫引起的)disease, kills as many as three million people every year ---- almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers ar
e difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect (感染) .They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next. According to paragraph 1, many people don't seek care because ___________.
| A．they are too poor |
| B．it is unusual to seek care |
| C．they can remain unaffected for long |
| D．there are too many people suffering from the disease |

It is a common fear among users of Facebook and other social media around the world—how to deal with a friend request from your boss or employee.
A survey released on Thursday found that 56 percent of Americans say it is irresponsible to be friends with a boss and 62 percent say it is wrong to be friends with an employee. But 76 percent believe it is acceptable to be friends with a workplace peer，according to the survey of 1，000 people by Liberty Mutual’s Responsibility Project.
"When the roles change what do you do then? Do you unfriend someone if they have now been promoted to be your boss or if you’re now their boss，”said researcher Kelly Holland. "We get into some really sticky situations there in terms of what people will think is responsible，”she said.
When using social media at work，73 percent say it is not appropriate to update your Facebook status，82 percent say you should not upload photos，72 percent believe tweeting is wrong and 79 percent say it is not acceptable to watch online videos. Yet 66 percent say it is fine to check your personal email while at work.
“When people focus on responsibility，they know what the responsible thing is to do but whether they are doing that in practice or not is a different story,”said Holland.
Americans are split on whether companies should review the social media profiles of job candidates with 52 percent saying it is appropriate and 48 percent saying it is unacceptable. Social media can also lead to some difficult decisions when it comes to family and relationships. Sixty percent of those polled say that it is“completely acceptable" to unfriend an ex-boyfriend or ex-girlfriend. More than 40 percent of parents believe it is irresponsible to post photos of children online. Thirty one percent monitor their children's Facebook accounts and almost 70 percent are friends with their children on Facebook or MySpace. But 72 percent limit the time their children spend on social media networks.
The poll was taken between January 12一15．The text is mainly about________

"What’s in a name?”According to Shakespeare’s Romeo and Juliet，there is not too much.“That which we call a rose by any other name would smell as sweet. "But Shakespeare may have been wrong. In most cultures，names matter a great deal.
Americans choose names for their children with care. Parents usually think about the impression a name gives，not its meaning. Most Americans would consider a “Jennifer” more attractive than a“Bertha"，for example. The last name，or，surname，must also be considered when choosing a first and middle name. A name like Lester Chester Hester would sound poetic，but odd. Parents would avoid names that remind them of people they don’t like. On the other hand，people might name their children after a respected elderly relative or even a famous person. The popularity of certain names can change with each new generation. Names that were once common，like Fanny or Elmer，sound old-fashioned today. But other names—like John and David，Mary and Sarah—have stood the test of time and continue to be favorites.
People in Ameica don’t always call their friends and relatives by their given names. Instead，they often use nicknames. Sometimes nicknames are short forms of a longer name. For instance，a girl named Elizabeth may be called Lisa，Beth or Betsy. As children grow up，they may decide for themselves which nickname they wish to be called.
Some people just go by the initials of their first and middle names，like B. J, or R. C. And of course，people may call their children or their sweethearts other special nicknames. Often they have a “sweet” flavor，like Honey or Sugar. What’s in a name? A world of significance. So if you’re choosing an English name for yourself，take care to choose a good one. A made—up name could sound strange to native English speakers. And a translation of your Chinese name may not make an appropriate name，either. But a good name can leave a positive and lasting impression. As an American politician once said，“In real life，unlike in Shakespeare，the sweetness of the rose depends upon the name it bears.”What does the underlined sentence in Paragraph 2 mean?
| A．People change names in order to be popular with the new generanon. |
| B．Names will change by themselves in order to be popular. |
| C．Some names may no longer be popular among the new generation. |
| D．No names can stand the test of time. |
When choosing names，you should stick to the following principles EXCEPT that
| A．the impression a name gives is more important than its meaning |
| B．you can name after a well-known person |
| C．surname should be paid attention to |
| D．you can create a name that is special |
