听力原文:M: So you're visiting San Francisco?

W: Yes, I just got here the day before yesterday. And you?

M: I'm a native.

W: Oh, really? Everyone else I've met so far has been a tourist like us. I was beginning to think that maybe there were no natives.

M: Well. San Francisco has a lot of different ethnic groups, so you might think you're seeing a lot of foreigners. But in fact, the city has a population of about 700 000 people.

W: What are the different ethnic groups?

M: Well, after whites, the largest one is blacks.

Throughout history people have been put to death for various forms of wrongdoing. The deat
h penalty is the most controversial penal practice in the modem world. Other harsh, physical forms of criminal punishment—referred to as corporal punishment (体罚) —have generally been eliminated in modem times. In the majority of countries, contemporary methods of punishment—such as imprisonment or fines—have abandoned infliction (施加) of physical pain. Although imprisonment and fines are universally recognized as necessary to the control of crime, the nations of the world are split on the issue of capital punishment. About 90 nations have abolished the death penalty and an almost equal number of nations retain it.

The trend in most industrialized nations has been to first stop executing prisoners and then to substitute long terms of imprisonment for death as the most severe of all criminal penalties. The United States is an important exception. The federal government and a majority of U.S. states provide for the death penalty, and on average 75 executions occur each year throughout the United States.

Since ancient times most governments have punished crimes by death as a routine part of the administration of criminal law. However, in the nfid-18th century, social critics began to criticize government practices they considered unjust, including capital punishment. The debate over whether governments should utilize the death penalty continues today.

Critics of capital punishment argue that it is cruel and insulting; while supporters assert that it is a uniquely effective punishment that prevents crime. However, advocates and opponents of the death penalty dispute the proper interpretation of statistical analyses of its preventing effect. Opponents of capital punishment see the death penalty as a human fights issue involving the limits of governmental power. In contrast, the advocates tend to regard capital punishment as an issue of criminal justice policy. Because of these alternative viewpoints, there will be further debate not only about what is the right answer on capital punishment, but about what type of question is being asked when the death penalty becomes a public issue.

According to the first paragraph, corporal punishment ______.

A.is a controversial penal practice now

B.is mere welcome than death penalty in most countries

C.is more effective than imprisonment and fines

D.is all history in most countries

English has never been the only language in use over the British Isles , and it certainly is not now!

English has never been the only language in use over the British Isles , and it certainly is not now! Welsh is still used in Wales. Some Welsh people still speak it as their mother tongue , and it is widely taught in Welsh schools. Some people in Scotland and in Ireland still use a language that is related to Welsh. It is called Gaelic. These languages have a long history in these islands - longer than the history of English. In addition , people from

overseas have settled in England quite recently during this century. In some industrial cities , though not generally in Britain , you find groups of people who speak Polish , and other groups speaking the languages of the Indian subcontinent. A survey of North London schools in the early 1980' s found that nearly a third of the children spoke a language other than English at home.

The majority of the 55 million people living in England use English all the time. Standard English , that is , written English , is in use throughout Britain. Spoken English , however , sounds very different in different parts of the country. There is a story , a play. by the famous writer George Bernard Shaw , about a professor of English Language who can tell you someone' s address when he hears that person speak! That is exaggeration of course. Not even a Professor , who has studied the sounds of English all his life , can really do that. However ,it is true hat most people who have lived for a long time in Britain can tell a number of things about the people as soon as they speak! Usually we cannot tell the speaker' s address

, but we can guess the part of the country where the person comes from. We can tell how well educated he or she is too! If an international user of English , like anyone of you here , happens to meet speakers from , say , the North or the West of England , you may find them hard to understand. Unless you understand what is going on your confidence in your ability to use the language may be badly shaken.

36. Gaelic is related to Welsh. ()

37. Welsh is not taught in schools anymore. ()

38. One third of the 55 million people in England speak other languages besides English at home ()

39. Written English is in use throughout Britain but spoken English sounds different in different parts of the country. ()

40. Most people who have lived for a long time in Britain can tell how well educated a person is by the way he/ she speaks. ()
