As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.
In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.
In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called "transactive memory (交互记忆)".
According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.The passage begins with two questions to ______.
| A．introduce the main topic |
| B．show the author's altitude |
| C．describe how to use the Interne. |
| D．explain how to store information |
What can we learn about the first experiment?

In transactive memory, people ______.
| A．keep the information in mind |
| B．change the quantity of information |
| C．organize information like a computer |
| D．remember how to find the information |
What is the effect of the Internet according to Sparrow's research?

| B．We are becoming more intelligent. |
| C．We have poorer memories than before. |
| D．We need a better way to access information. |

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic talked about by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only can these two diseases be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life can be longer.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary (遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing with hereditary diseases. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to make human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, even a cow, therefore these people predict that human babies would be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
6What does “these two killers” in the second paragraph refer to?
| A．Gene technology and another treatment of the two diseases. |
| B．The two murderers who killed the cloned baby. |
| C．Hereditary disease and cancer. |
| D．Cancer and heart disease. |
In what way can gene technology help to treat hereditary diseases?
| A．Using gene technology, a scientist finds the wrong gene and corrects it. |
| B．Using gene technology, people with hereditary diseases can live longer. |
| C．Using gene technology, human babies can also be cloned. |
| D．Doctors can cure cancer and heart disease with the help of gene technology. |
What is the main purpose of writing the text?
| A．Explaining that gene technology will also do great harm to human race. |
| B．Telling the readers the positive effects gene technology has on people’s life. |
| C．Expressing the writer’s idea that gene technology will benefit people. |
| D．Informing people that gene technology helps clone babies in large quantities. |
The Basics of Math—Made Clear
Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas. These 30 fantastic lectures are designed to provide students with an understanding of arithmetic(算数) and to prepare them for Algebra (代数) and beyond.
The lessons in Basic Math cover every basic aspect of arithmetic. They also look into exponents (指数), the order of operations, and square roots. In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically.
Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students. The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and overcome their anxiety about this amazing — and completely understandable — field of study.
By the conclusion of the course, students will have improved their understanding of basic math. They will be able to clear away the mystery (神秘性) of mathematics and face their studies with more confidence than they ever imagined. In addition, they will strengthen their ability to accept new and exciting mathematical challenges.
Professor H. Siegel, honored by Kentucky Educational Television as “the best math teacher in America,” is a devoted teacher and has a gift for explaining mathematical concepts in ways that make them seem clear and obvious.

You’ve just come home, after living abroad for a few years. Since you’ve been away, has this country changed for the better or for the worse?
If you’ve just arrived back in the UK after a fortnight’s holiday, small changes have probably surprised you—anything from a local greengrocer suddenly being replaced by a mobile-phone shop to someone in your street moving house.
So how have things changed to people coming back to Britain after seven, ten or even 15 years living abroad? What changes in society can they see that the rest of us have hardly noticed—or now take for granted? To find out, we asked some people who recently returned.
Debi: When we left, Cheltenham, my home town, was a town of white, middle-class families—all very conservative (保守的).The town is now home to many eastern Europeans and lots of Australians, who come here mainly to work in hotels and tourism. There are even several shops only for foreigners.
Having been an immigrant (移民) myself, I admire people who go overseas to find a job. Maybe if I lived in an inner city where unemployment was high, I’d think differently, but I believe foreign settlers have improved this country because they’re more open-minded and often work harder than the natives.
Christine: As we flew home over Britain, both of us remarked how green everything looked. But the differences between the place we’d left behind and the one we returned to were brought sharply into focus as soon as we landed.
To see policemen with guns in the airport for the first time was frightening — in Cyprus, they’re very relaxed — and I got pulled over by customs officers just for taking a woolen sweater with some metal-made buttons out of my case in the arrivals hall. Everyone seemed to be on guard. Even the airport car-hire firm wanted a credit card rather than cash because they said their vehicles had been used by bank robbers. But anyway, this is still a green, beautiful country. I just wish more people would appreciate what they’ve got.After a short overseas holiday, people tend to ______ .
| A．expect small changes | B．notice small changes |
| C．welcome small changes | D．exaggerate (夸大) small changes |
How does Debi look at the foreign settlers?
| A．Cautiously. | B．Skeptically. |
| C．Positively. | D．Critically. |
When arriving at the airport in Britain, Christine was shocked by ______ .
| A．the tight security | B．the messy arrivals hall |
| C．the relaxed policemen | D．the bank robbers |
Which might be the best title for the passage?
| A．Life in Britain. | B．Britain in Memory. |
| C．Britain in Future. | D．Back in Britain. |
When something goes wrong, it can be very satisfying to say, “Well, it’s so-and-so’s fault.” or “I know I’m late，but it’s not my fault; the car broke down.” It is probably not your fault, but once you form the habit of blaming somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.
Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.
This is what being a winner is all about—creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “whose fault it is.” Once you are confident about your power over bad situations, problems are just stepping stones for success.According to the passage, winners .
| A．blame themselves rather than others |
| B．meet with fewer difficulties in their lives |
| C．have responsible and able colleagues |
| D．deal with problems rather than blame others |
The underlined word remedy in Paragraph 1 is closest in meaning to ______.
| A．improve | B．accept |
| C．avoid | D．consider |
When problems occur, winners take them as ______.
| A．excuses for their failures | B．chances for self-development |
| C．challenges to their colleagues | D．barriers to greater power |
Which of the following is the best title for the passage?
| A．A Winner’s Opportunity. | B．A Winner’s Problem. |
| C．A Winner’s Secret. | D．A Winner’s Achievement. |
