     Members of the working class have blue-collar jobs. They are construction workers, truck drivers,

mechanics, steel workers, electricians, and the like. What makes this class differ from the lower class is,

first, longer periods of employment-and therefore, more fixed incomes -and, second, employment in skilled

or semiskilled (半熟练的 ) occupations, not unskilled ones. Although unemployment hits all levels of the

American economy, including those of skilled and semi-skilled workers, it is most common at the bottom

of the class structure and increasingly less common at each level upward. They consider themselves to be

respectable and hard working and they look down upon members of the"lower" class, whom they often

consider to be lazy, dis-honest, and too ready to exploit public assistance.

     Most people in the working class have at least high school education. Many have some experi-ence of

college ( especially community college), though few are college graduates.

     Unionization has helped the working class, but a rapidly changing economy and frequent periods of high

unem-ployment make it difficult for most of its members to be able to increase their savings great-ly.

Purchasing a house for people in this class is extremely difficult, although a certain percentage may receive

houses from their parents. (Home-owning rises with social class. )

      A greater number of the members of the working class take relatively little satisfaction in their jobs,

because much of their work is ordinary and boring. As a result, many seek their main satis-faction in

recreational ( 娱乐的) activities. Many members of this class would like to earn enough money to leave their

jobs and start their own businesses, though few make it. Many place their expectations on their children,

hoping that they at least will rise in the ladder of success, American style.

1. Which of the following is true about the working class.?

A. They are often employed as skilled and semi-skilled workers.

2. The underlined word "hit" (paragraph 1 ) roughly means _____.

A. strike with a blow

3. Most people in the working class _____.

A. have difficulty increasing their savings greatly

B. have at least some experience of college

C. receive houses from their parents

D. buy houses by themselves

A. they could not rise in the ladder of success
