Generation gap refers to the difference in ideas, feelings, and interests between the older and younger people. It is especially considered as causing a lack of communication and understanding between the two generations.
There is apparent generation gap between the young and the old nowadays. The younger generation is essentially different from the older generation. The young people live in a new age completely different from the old. They have grown up more happily and are not so dependent on adults as their parents were. They are better educated and enjoy more freedom. They easily accept new things and new ideas. They are more concerned with the present and the future, whereas the world of the older people has vanished, and they do not understand all of the problems of the modern world. They grew up in a world which was different from today's world. They often talk about "the good old days" and tend to assert old things and ideas. They don't like to feel that their beliefs and values are being questioned and threatened. They would like the young to learn from them, but the young refuse to accept their values. They cannot understand why the young complain about the conventional things and old systems and why they want to make changes in these things to fit the needs of modern society, As a result, the old people think the young are not what they were, and most young people are unable to learn from the parents and elders who they will never be.
In order to reconcile the differences, both generation should realize that the world has changed, and that new responses are necessary for many of the problems of society. Besides, some forms of organizations should be established to help the young and the old exchange their ideas and strengthen their mutual understanding so as to bridge the gap.
One important reason for the difference existing between the young and the old is that ______.
A．they live in different ages
B．they live in different countries
C．they live in separate planets
D．they hate each other

The modern sailing ship was developed by a man who never went to sea. He was Prince Henry of Portugal, the younger son of the Portuguese king and in English princess.
Prince Henry lived in the fifteenth century. As a boy he became devoted to the sea, and he dedicated (devoted) himself" to improving the design of Ships and the methods or sailing them. In 1416, when he was twenty-two. Henry founded a school for mariners, to which he invited everyone who could help him —— Jewish astronomers, Italian and Spanish sailors, and Arab mathematicians and map makers who knew how to use the crude compass of the day and could improve it.
Henry's goal was to design and equip vessels that would be capable of making long ocean voyages without having to hug (keep close to) the shore. The caravel carried more sail and was longer and slimmer than any ship then made, yet was tough enough to withstand gales at sea. He also developed the carrack, which was a slower ship, but one that was capable of carrying more cargo.

Giving Up Smoking A number of devices are available to help a person quit smoking. Nicotine(尼古丁) patches are small, nicotine-containing adhesive(粘着性的) discs applied to the skin. The nicotine is slowly absorbed through the skin and enters the bloodstream. Over time, the nicotine dose is reduced and eventually the desire for nicotine is eased. Nicotine gum works in a similar manner, providing small doses of nicotine when chewed.
The benefits of giving up smoking include the immediate reduction of harm to the health of the smoking and easily admission to social activities and institutions that ban smoking. In a 1988 report, the U.S. Surgeon General declared cigarette smoking to be more harmful and expensive than the use of cocaine(可卡因) , alcohol, or heroin. Recent evidence supports this claim.
The United States government has collected a special tax on cigarettes for several decades. The rate rose from 8 cents per pack of 20 cigarettes in 1951 to 24 cents per pack in 1993. In other developed countries, the cigarette tax rate is much higher, ranging from 50 percent in Switzerland to 85 percent in Denmark.
In the United States, the first direct action to check smoking was the regulation of a warming on cigarette packages by the Federal Trade Commission. This warning took effect in 1964 and was strengthened in 1969 to read:“Warning: The Surgeon General Has Determined That Cigarette Smoking Is Dangerouis to Your Health.”In 1971 all cigarette advertising was banned from radio and television, and cities and states passed laws requiring nonsmoking sections in public places and workplaces.
第11题：Which of the following can help a person quit smoking？
A．Using nicotine patches.
