Since the beginning of history, man has been attracted by the idea of living forever, of winning the fight against death and disease. So far, this has only remained a dream. Many people have wondered whether it would be possible to find a way to preserve human bodies, and what would be the best way.
It has long been known that meat of fruit can be kept fresh for long periods by freezing; in ancient China, for example, food was stored with ice to keep it fresh. This method could also be useful for preserving humans.
However, most living beings that exist under warm conditions die when frozen. This is because of the harmful effects of freezing ice crystals(晶体), which not only are larger than the volume(体积) of the water originally in the cells, but also form sharp cutting shapes that harm the cells.
In the 1940s Dr B.J. Luyet and a group of scientists in England were working on the problem of freezing cells without damaging them. Since the harm caused by ice crystals was the main cause of damage, Luyet suggested removing some or all of the water from the cells before freezing them.
Using living cells form chicken, Luyet and his assistants discovered that they could partly dry the chicken cells, using a mixture of the white part of an egg and glycerin (丙三醇). Some success was obtained. The chicken cells were dried, frozen for a period of time, and then carefully unfrozen. Almost all the cells recovered when they reached normal temperatures.
Since then, the cooling of whole animals to a temperature far below freezing point for later unfreezing has become more of a possibility, and the glycerin method would probably be used to accomplish this. When this can be done completely and successfully, science will have moved much closer to its aim of freezing and storing incurable patients until the day they can be cured.

The USA is a land of immigrants. Between 1815 and 1914, the world witnessed the greatest peaceful migration in its history: 35 million people, mostly Europeans, left their homelands to start new lives in America. Why did these people risk everything by leaving their homes and families?

First, what forced emigrants to make the decision to leave? One major cause for European farmers to leave was the rise in population which in turn led to land hunger. Another was politics. There was an increased taxation（税收） and the growth of armies, and many young men fled eastern Europe to avoid being forced to join the army.

Physical hunger provided another pressing reason. Following the collapse （衰退）of the economy of southern Italy in the 1860s, hundreds of thousands decided to start a new life in America. Religion also encouraged millions to leave the Old World.

In short, people chose to leave their homes for social, economic and religious reasons. As a result, by 1890 among a total population of 63 million, there were more than nine million foreign-born Americans.

But what were the attractions? First of all, there was the promise of land which was so scarce in Europe. Next, factories were calling for workers, and pay conditions were much better than back home. Men were needed to open up the West and build the long railroads, and new towns needed settlers to live in and to develop business. There was the space for religious people to practice their faith in peace.

This immigration meant that by around the 1850s Americans of non-English had started to be more than those of English. As we know, there were losers. To start with, there were those unwilling immigrants, the slaves who had been used as a source of cheap labour. Nor should we forget the equally unlucky American Indians. By 1860 there were 27 million free whites, four million slaves and a mere 488,000 free blacks.

Nowadays, the USA is still seen by millions as the Promised Land. As always, it remains an attractive place to those who think it will offer them a second chance.

1.What is not the cause for people to leave their homeland?

A. The search for religious freedom.

B. The search for adventure.

C. Unwillingness to join the army.

D. Economics.

2.Why was life of the 19th Century European farmers difficult?

A. There was no land.

B. There was no peace.

C. The population had gone down.

D. There were too many of them.

3. Which of the following was not an attraction of the USA?

A. Employment B. A healthy life

C. freedom of religion D. Business opportunities

4.What is the topic of this passage?

A. The USA is still seen by millions as the Promised Land.

B. The USA is a land of immigrants.

C. Religion encouraged millions to leave the Old World.

D. About one-eighth of non-native born Americans live in the USA in 1890.

5. The American Indians __________.
