江苏建设先进制造业基地拥有的优势 

（一）制造业产能大。2005年，江苏省规模以上制造业企业总产值达30816.65亿元。 

（二）劳动力成本低廉。2005年，江苏省制造业在岗职工平均工资为16937元，折合2068美元，不足美、日、德、韩的十分之一。 

（三）劳动力素质高。随着义务教育的普及和高校招生规模的扩大，进入劳动力市场的高素质劳动者呈逐年增加的趋势。2005年，江苏有11.4万名理工科大学生和12万名职业技工学校毕业生进入劳动力市场，工程技术人员的保有量为20.96万人。

单项选择题

Modern industrial society grants little status to old people. In fact, such a society has a system of built-in obsolescence. There is no formal system for continuing our education throughout our life in order to keep up with rapidly changing knowledge. When our education and job skills have grown obsolete, we are treated exactly like those who have never gained an education or job skills and are not encouraged or given the opportunity to begin anew.As a society becomes more highly developed, the overall status of older people diminishes. Improved health technology creates a large pool of old people, who compete for jobs with the young. However, economic technology lowers the demand for workers and creates new jobs for which the skills of the aged are obsolete, forcing older people into retirement. At the same time, young people are being educated in the new technology and are keeping pace with rapid changes in knowledge. Finally, urbanization creates age-segregated neighborhoods. Because the old live on fixed incomes, they must often live in inferior housing. All these factors — retirement, obsolete knowledge and skills, inferior standards of living — lower the status of the aged in society.A century ago, when one could expect to live only to 50 or so, the life span more or less coincided with the occupation and family cycle. But today the average life span allows for fifteen to twenty years of life after these cycles. It appears that our life span is outpacing our usefulness in society.

According to the first paragraph, which of the following is true

A．People don’t have to gain education.

B．People don’t have to learn job skills.

C．People don’t have to be treated as equals.

D．People don’t have chances to begin anew.
