In 1879, a group of explorers made an incredible find. They discovered paintings of remarkable beauty on the walls of a cave in Spain. Some scientists believed that these paintings were created by early humans from the Stone Age, between ten and thirty thousand years ago. Other scientists and the public did not believe the claim, but over the years, it was proven correct. Our ancestors had incredible artistic talents.

Most of the cave art that has been discovered has been found in Spain and France. A smaller number of such caves are located in Italy, Portugal, Russia, and other countries. Scientists believe that many more caves will be discovered in the coming years, and are concentrating their efforts on Africa and the area between Europe and Asia. These two regions of the world were, populated first by humans.

Cave art was carved or painted on the walls and roofs of caves, usually near the entrance. The entrance area was probably chosen to take advantage of daylight and to allow many people to view the paintings. In some cases, the art appears much deeper in caves and requires artificial light. Evidence suggests that the artists used torches or shallow bowls in which animal fat was burned.

9.What was the response of general public to the discovery of cave art made by Stone Age people?

A. They believed it at first.

B. They did not believe it.

C. They thought it was beautiful.

D. They ignored it.

A. It does not burn.

B. Stone Age artists used it to preserve their paintings.

  Can you imagine a stranger will read your e-mails without your permission or scan the website you’ve visited or perhaps someone will casually glance through your credit card purchases or cell phones bills? All of the things may happen to you one day.

In fact, it’s likely that some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen or even do something that may bring a disaster to you.

Psychologists tell us boundaries are healthy, and that it’s important to reveal to friends, family and lovers at appropriate times. But few boundaries remain nowadays. The digital bread crumbs you leave everywhere make it easy for strangers to know who you are, where you are and what you like. In some cases, a simple Google search can leak the deepest thought in your mind. Like it or not, increasingly we live in a world where you simply cannot keep a secret.

The key question is: Does that matter? For many Americans, the answer apparently is “No”.

When opinion polls ask Americans about privacy, most of them say they are really concerned about losing it. And 60 percent of the respondents say they feel their privacy is “slipping away, and that bothers me”.

But people say one thing and do another. Only a small of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站) to avoid using the EZ-Pass system that track automobile movements. Privacy economist Acquisti has run a series of tests that reveal people will give up personal information such as telephone number, address, or social security numbers just to get their hands on a pitiful 50-cent-off coupon(优惠券). But privacy does matter—at least sometimes. It’s like health; when you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it. Without privacy, one will be naked in front of others.

1.What would psychologists advise on the relationships between friends?

2.Why does the author say “we live in a world where you simply cannot keep a secret”?

3.What should be the best title for the text?

Language is a way to communicate with each other. We started to learn language when we were born. However, people are used to speaking their native language, so immigrants are having many problems between the first generation and the second generation because they don’t have the same native language. Also, the second generation is losing their identity. Especially in America, there are many immigrants that came from different countries to succeed in the States. Because they suffer in lots of areas such as getting a job and trying to speak English, they want their children to speak English, not only at school, but also at home in order to be more successful. Because of this situation, their children are losing their identity and, even more, they are ignoring their parents whose English is not very good. I think most immigrants are trying to preserve their native language in their new country, but this doesn’t help very much in getting a good job. My aunt taught Korean to her children not to help them succeed in the U.S. She did so, hopefully, to help them establish a Korean identity. Though the second generation was born in the new country, they often get confused about their identity because they look different from others, and also, if they visit their parents’ country, they will probably feel different from other people there too. My cousins told me that when they visited Korea a few years ago, they felt different from other Koreans. They could even feel it just strolling around the street because they wore different clothes and walked differently. We must realize that language is important and valuable for many reasons. Immigrants should make an effort not to be ignored by their children and let them understand their background by teaching them the parents’ language. This is very important, not only for the harmony of the family, but also in helping the second generation establish their identity.
