It is a surprising fact that the population ageing is particularly rapid in developing countries. For example, it took France 115 years for the proportion of older people to double from 7 percent to 14 percent. It is estimated to take China a mere 27 years to achieve this same increase. What are the implications of these increased numbers of older folk？ (76) One of the biggest worries for governments is that the longer people live, the more likelihood there is for diseases and for disability(残疾). Attention is being paid to the need to keep people as healthy as possible, including during old age, to lessen the financial burden on the state. (77)Another significant problem is the need for the younger generations to understand and value the older people in their society. In some African countries, certainly in Asia, older people are respected and regarded as the ones with special knowledge. Yet traditions are fading away daily, which does not ensure the continued high regard of older people. As society changes, attitudes will change. Much needs to be done to get rid of age discrimination(歧视)in employment. Life-long learning programs need to be provided to enable older people to be active members in a country's development. 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. 第6题：The proportion of older people________. A. is bigger in developed countries than in developing countries B. is one-seventh 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

There can be no doubt that the growth in advertisement is one of the most striking features of the western world in this century. Many businesses such as those handling frozen foods, liquor, tobacco and medicines have been built up largely by advertisement. We might ask whether the cost of advertisement is paid for by the producer or by the customer. (19) Since advertisement forms part of the cost of production, which has to be covered by the selling price, it is clear that it is the customer who pays for advertisement. However, if large scale advertisement leads to increased demand, production costs are reduced, and the customer pays less. It is difficult to measure exactly the influence of advertisement on sales. When the market is growing, advertisement helps to increase demand. When the market is shrinking, advertisement may prevent a bigger fall in sales than would occur without its support. What is clear is that businesses would not pay large sums for advertisement if they were not convinced of its value to them. Advertisement is often used to______. A．deceive customers B．increase production C．arouse suspicion D．push the sale

A．not famous B．well known for something bad C．well known for something exciting D．well known for something permanent

A．超越 B．越来越 C．越......就越...... D．更多
