Cancer is feared by everyone. And this fear is reaching epidemic(流行性) proportions. Not the disease itself — there is no such thing as a cancer epidemic. Except for lung cancer, mostly caused by cigarette smoking ,the incidence rates are leveling off, and in the case of some kinds of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an anxiety, The earth itself is coming to seem like a huge carcinogen(致癌物). The ordinary, more or less scientific statement that something between 80 and 90 percent of all cancers are dun to things in the environment is taken to mean that none of us will be safe until the whole environment is “cleaned up.” This is not at all the meaning.
The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in various societies around the world — for example, the high proportion of liver cancer in Africa and the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America. These data indicate there may be special and specific environmental influences, largely based on personal life-style, that determine the incidence of various forms of cancer in different communities — but that is all the data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same everywhere.

大家都害怕癌症，这种恐慌正在蔓延开来。倒不是惧怕癌症本身，癌症也并非流行病。除了主要由于抽烟引起的肺癌之外，癌症的发病率不但稳定下来，而且有些还正在减少。但人们却都谈“癌”色变，陷入一种惶恐不安之中。地球本身看上去就越来越像一个巨大的致癌物。有一种多多少少带点科学性的普遍说法，认为80%到90%的癌症都是由于环境中的物质引起的。也就是说，直到把整个环境都“清洁干净”，我们才没有危险。然而，数据所说明的真正含义根本不是这样。
80%这个数据是基于全球不同地区癌症发病率的差异统计出来的。比如，非洲和远东地区肝癌比例高，日本胃癌比例高，西欧和北美的乳腺癌比例高，但是日本和非洲部分地区乳腺癌病例较少，美洲肝癌病例也较少。这些差异使人难于置信。这些数据表明，不同地区癌症的发病率可能受到环境中某些具体和特殊的影响，其实这种影响主要是由个人的生活方式决定的。所以数据不能说明全部情况。如果把所有病例合计起来，也许各地总体发病率都大致相同。
part 2Upon reaching an appropriate age (usually between 18 and 21 years)， children are encouraged， but not forced， to “leave the nest” and begin an independent life. After children leave home they often find social relationship and financial support outside the family. Parents do not arrange marriages for their children， nor do children usually ask permission of their parents to get married， Romantic love is most often the basis for marriage in the United States; young adults meet their future spouses (配偶) through other friends， at jobs， and in organizations and religious institutions， Although children choose their own spouses， they still hope their parents will approve of their choices.
In many families， parents feel that children should make major life decisions by themselves. A parent may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do precisely the opposite of what their parents wish in order to assert their independence. A son may deliberately decide not to go into his father’s business because of a fear that he will lose his autonomy in his father’s workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family Coexisting with such love in the American family are cultural values of self – reliance and independence.
1. The writer discusses the marriage of young adults in order to show which of the following?
A) They enjoy the freedom of choosing their spouses.
B) They want to win the permission of their parents.
C) They have a strong desire to become independent.
D) They want to challenge the authority of their parents.
2. Most young adults in the U.S. get married for the sake of ____.
A) love
B) financial concern
C) their parents
D) family background
3. Based on the passage， it can be assumed that ______.
A) American young adults are likely to follow the suit of their parents
B) most American people never make major decisions for their children
C) American young adults possess cultural values of independence
D) once a young person steps into his twenties， he will leave his home permanently

A) he wishes to make full use of what he has learnt in school

答案：
CACBA
子女一旦到适当年龄(通常是18至21岁)，要鼓励而不是强迫他们“离开窝的，财政的巢”，开始独立生活。小孩离开家后，往往在外能够与人交往，并自谋出路。父母不为子女安排婚姻，子女结婚也通常无需获得父母同意。在美国，浪漫的爱情往往是婚姻的`基础，青年人通过朋友在学校、单位、组织以及宗教团体认识自己的，爱情的未来的伴侣。尽管子女自己择偶，他们仍然希望父母能认同他们的选择。
许多家庭的父母认为，应由子女自己来做他们生活中的重大决定。家长可能会设法影响子女去从事某一职业，但子女也有选择其它职业的自由。有时为了证实自己的独立性，子女从事的工作正好与父母希望的相反。儿子可能执意不去父亲的企业工作，因为担心在那里就不能独立自主。这种不依靠父母的独立性并不意味着父母与子女之间缺乏爱心。父母和子女之间普遍都有挚爱，美国家庭也毫不例外。只不过在美国家庭之中，还融合了自主、独立的文化价值观念。
