As Internet users become more dependent on the Internet to store information, are people remembering 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 computer. The information was in a specific computer folder (文件夾). 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 (交互記憶)"

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(獲取) 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.

1.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

2.What can we learn about the first experiment?

A. Sparrow's team typed the information into a computer.

B. The two groups remembered the information equally well.

C. The first group did not try to remember the formation.

D. The second group did not understand the information.

3.In transactive memory, people ______.

A. keep the information in mind

B. change the quantity of information

C. remember how to find the information

D. organize information like a computer

4.What is the effect of the Internet according to Sparrow's research?

A. We are becoming more intelligent.

B. We are using memory differently.

C. We have poorer memories than before.

D. We need a better way to get information.

Chimpanzees，long considered reluctant to share，apparently can display selfless tendencies，revealing one more key way our closest living relatives are like humans，scientists find． These findings could shed light on the evolution of altruism in humans．

Previously，a belief was widely held that human altruism evolved only after humans split from their ape cousins about 6 million years ago．In recent years，however，research has revealed just how much chimpanzees have in common with us．They can hunt with spears，play with dolls and mourn their partners'death.

“Most of the earlier studies had presented the apes with a complex implement that helped them deliver food to themselves or others，often so complicated that the experiments tested tool skills rather than social tendencies，”De Waal told Live Science．“Ours is the first study that uses no such implement at all.”

In addition to using complex food-delivery systems，past experiments often placed the chimpanzees so far apart that they might not have realized how their actions benefited others．In these new，simplified experiments，two apes were housed next to each other with a screen through which they could see each other．Then，one chimpanzee had to choose between two differently colored tokens （幣） from a bin，one of which represented a pro-social （親社會(huì)的） option，the other a selfish option．The pro-social option would cause both chimpanzees to receive a piece of banana wrapped in paper．The selfish option only rewarded the ape who made the choice.

In a study with seven adult female chimps placed into various pairs，the scientists found all the apes showed a definite preference for the pro-social option．“For me，the most important finding is that like us，chimpanzees take into account the needs and wishes of others，”researcher Victoria Horner，said.

The chimpanzees behaved especially altruistically toward partners who either patiently waited or gently reminded them that they were there by drawing attention to themselves．They were less likely to reward partners who pressured through making a fuss，begging persistently or spitting water at them．This is opposite to a long-standing view that the chimpanzees only share food under pressure.

1.The word“ altruism” （paragraph 1） is closest in meaning to ______.

A． selfishness

B． selflessness

C． willingness

D． reluctance

2.Recent researches are performed with less complicated implements mainly to ______.

A． show that chimps are only good at using implements

B． see whether chimps are willing to share food with others

C． find out if chimps are likely to reward partners

D． test chimps’ social tendencies instead of tool skills

3.Which of the following might be the best title of the passage？

A． Evolution History of Altruism in Humans

B． Similarities between Chimps and Mankind

C． Chimps Do Show Selfless Behavior

D． Chimps Only Share Food under Pressure

Recently, the Ministry of Education has issued a requirement which students should be given labor education while at the school, which arouses a heated debate.

As for students, opinion are divided. Some students think that it will be great benefit for their health, enabled them to be well developed. On the other hand, some students hold the view that this kind of education will take up our time, which will be spent studying otherwise. But it will have a negative effect on their grades.

It was true that students are given little chance of laboring nowadays, thus lacking the sense of labor. So as far as I am concerned, students definite should receive labor education so that they will value more that labor brings about.

科目：高中英語 來源：2015-2016學(xué)年山西臨汾第一中學(xué)高一12月月考英語試卷（解析版） 題型：閱讀理解

(Q = Question; A = Answer)

Situation I

Q: If someone sits right next to me in an empty movie theater, is it rude to move?

A: Maybe, but nobody will fault you for it. Chances are that the close sitter doesn’t realize he disturbs you, so he may miss your annoyance. You undoubtedly aren’t the first person he’s met who needs enough room. Forgive his bad judgment, move quietly and enjoy the show.

Situation II

Q: If I use the bathroom at a store, do I need to buy something?

A: Consider frequency and urgency. Is this a one-time thing or an emergency? If so, you don’t have to buy anything, but it would be kind if you did. However, if you regularly use the bathroom at this place, then you are a customer, and you should act like one.

Situation III

Q: If someone is talking loudly on the bus, is there a nice way to ask him to keep it down?

A: No. Try other means: 1) Stare at him until he gets aware of it and quiets down. 2) Lift your finger in a silence motion(動(dòng)作) and smile. 3) Put on earphones and ignore him.

Situation IV

Q: If I remember my friend’s birthday a day late, should I apologize or just wish her a happy birthday like nothing happened?

A: This is the reason why the word belated was invented. “Happy belated birthday!” is short for: “Well, I know I forgot, but then I remembered. Forgive me and happy birthday.”

Situation V

Q: Can I lie about seeing a text because I was loo busy or lazy to respond to it?

A: Don’t lie. Receiving a text does not mean you need to respond(回復(fù)) to it. Why waste a perfectly good lie when the truth will serve? “Yes,” you can say if ever asked, “I saw it.” No explanation is needed as to why you don’t respond.

1.How will you quiet someone down in a public place?

A. By talking to him directly.

B. By pointing angrily at him.

C. By looking purposefully at him.

D. By making fun of him continuously.

2.The underlined word “belated” in Situation IV probably means ________.

A. delayed B. returned C. predicted D. regretted

3.You will get annoyed in a theater when ________.

A. a person is too rude to you

B. a person sits too close to you

C. a person is too active

D. a person talks too loudly

4.What is the passage mainly about?

A. Different ways to change others’ manners.

B. Good manners to talk to people.

C. Proper manners to offer help to others.

D. Modern ways to mind your manners.
