Social security policies need to be established to provide adequate income protection for older people. Both public and private schemes are vital in order to build a suitable safety net.

　　To achieve equality in such matters will take considerable time and effort. One thing is sure: there is no time to be lost.

　　5．The proportion of older people ________.

　　A．is bigger in developed countries than in developing countries

　　B．is one­seventh of the population in developing countries

　　C．will increase much faster in China than in France

　　D．will be sixty percent in developing countries by 2020

　　解析：选C　推理判断题。根据文章第二段内容可知，在法国，115年里老年人口的比例从7%增长到了14%，而在中国仅仅用了27年的时间就达到了这个增长幅度。因此可推知，将来中国老龄人口比例的增长速度要比法国快得多。故答案选C。

　　6．According to the passage, which of the following are governments most worried about?

　　A．The diseases and disability of older people.

　　B．The longer life and good health of people.

　　C．The loss of taxes on older people.

　　D．The increasing respect for older people.

　　解析：选A　细节理解题。根据第三段第二句“One of the biggest worries for governments is that the longer people live, the more likelihood there is for diseases and for disability.”可知，政府担心，人们活的寿命越长，人们的健康压力会越大。答案选A。
