About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table, I couldn't help overhearing parts of their conversation. At one point the woman asked, “So, how have you been?” And the boy—who could not have been more than seven or eight years old—replied. “Frankly, I've been feeling a little depressed lately.”

This incident stuck in my mind because it confirmed my growing belief that children are changing. As far as I can remember, my friends and I didn't find out we were “depressed”, that is, in low spirits, until we were in high school.

Undoubtedly a change in children has increased steadily in recent years. Children don't seem childlike anymore. Children speak more like adults, dress more like adults and behave more like adults than they used to.

Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was no longer exists. Why?

Human development depends not only on born biological states, but also on patterns of gaining social knowledge. Movement from one social role to another usually involves learning the secrets of the new social positions. Children have always been taught adult secrets, but slowly and in stages; traditionally, we tell sixth graders things we keep hidden from fifth graders.

In the last 30 years, however, a secret-revelation（揭示） machine has been equipped in 98 percent of American homes. It is called television. Television passes information to all viewers alike, whether they are children or adults. Unable to resist the temptation （誘惑）, many children turn their attention from printed texts to the less challenging, more attractive moving pictures.

Communication through print, as a matter of fact, allows for a great deal of control over the social information which children will gain. Children must read simple books before they can read complex materials.

1.According to the author, feeling depressed is ____________.

A. a sure sign of a mental problem in a child

B. a mental state present in all humans, including children

C. something that cannot be avoided in children's mental development

D. something hardly to be expected in a young child

2.According to the author, that today's children seem adult-like results from ____________.

A. the widespread influence of television

B. the poor arrangement of teaching content

C. the fast pace of human scientific development

D. the rising standard of living

3.What does the author think of communication through print for children?

A. It enables children to gain more social information.

B. It develops children's interest in reading and writing.

C. It helps children to read and write well.

D. It can control what children are to learn.

4.What does the author think of the change in today's children?

A. He feels their adult-like behavior is so funny.

B. He thinks the change worthy of note.

C. He considers it a rapid development.

D. He seems to be upset about it.

There are thousands of products of all colors and shapes in a supermarket, making you believe that they are worth a try. How? Packaging is the silent but persuading salesman.

There on the shelves, each bottle, can ,box, and jar has been carefully designed and measured to speak to the inner self of the consumer, because he/she is buying not only a product but also his/her belief in life. Scientists have studied consumer behavior recently and found that the look of the package has a great effect on the “quality” of the product and on how well it sells, because “consumers generally cannot tell between a product and its package. Many products are packages and many packages are products.”, as Louis Cheskin, the first social scientist studying consumers’ feelings for packaging, noticed.

Colors are one of the best tools in packaging. Studies of eye movement have shown that colours draw human attention quickly. Take V8 for example. For many years, the bright red color of tomatoes and carrots on the thin bottle makes you feel that is it very good for your body. And the word “green” today can keep food prices going up.

Shapes are another attraction. Circles often suggest happiness and peacefulness, because these shapes are pleasing to both the eye and the heart. That’s why the round yellow M signs of McDonald’s are inviting to both young and old.

This new consumer response to the colors and shapes of packages reminds producers and sellers that people by to satisfy both body and soul.

A. the pleasing color of the package

B. he special taste of the product

C. the strange shape of the package

D. the belief in the product

2.If a package or a product is round in shape, it can ____________.

A. bring excitement to the consumers

A. starting to notice the importance of new food

B. enjoying the beauty of nature more than before

4.It can be inferred from the passage that V8 is a kind of ________.
