[单项选择]
Ours has become a society of employees. A hundred years or so ago only one of every five Americans at work was employed, i. e., worked for somebody else. Today only one out of five is not employed but working for himself. And when fifty years ago "being employed" meant working as a factory laborer or as a farmhand, the employee of today is increasingly a middle-class person with a substantial formal education, holding a professional or management job requiring intellectual and technical skills. Indeed, two things have characterized American society during these last fifty years; middle-class and upper-class employees have been the fastest-growing groups in our working population—growing so fast that the industrial worker, the oldest child of the Industrial Revolution, has been losing in numerical importance despite the expansion of industrial production.

[单项选择]For Tony Blair, home is a messy sort of place, where the prime minister’s job is not to uphold eternal values but to force through some unpopular changes that may make the country work a bit better. The area where this is most obvious, and where it matters most, is the public services. Mr Blair faces a difficulty here which is partly of his own making. By focusing his last election campaign on the need to improve hospitals, schools, transport and policing, he built up expectations. Mr Blair has said many times that reforms in the way the public services work need to go alongside increases in cash.
Mr Blair has made his task harder by committing a classic negotiating error. Instead of extracting concessions from the other side before promising his own, he has pledged himself to higher spending on public services without getting a commitment to change from the unions.
