11. How to Solve the Housing Problem in Big Cities
 The shortage of housing in big cities is one of the most serious problems of modern living. Increasing numbers of people are finding it difficult to conduct normal family and work duties because they either have nowhere to live or their houses are inadequate. This is a problem that requires an urgent solution because it leads to social unrest and economic inefficiency.
 Some people suggest that the solution to the problem is to build more high-rise apartments, others are in favor of underground housing areas. I prefer the first idea, because it is cheaper to build above ground than below. Besides, people prefer to live in the open air and see the sunshine.
The second idea is not practical. One reason for this is that it is dangerous to construct living places under streets and buildings. Another reason is that it would take too much time to carry out, and in the meantime the number of people waiting for houses would increase, thus making the problem worse.

12. How to Solve the Problem of Heavy Traffic
Nowadays, China’s cities are getting increasingly crowded. The rapid increase in population is being made worse by the steady influx of people from the rural areas seeking employment. As a result, heavy traffic is a big headache, with all the roads packed with cars, bicycles and pedestrians.
In my opinion, there are two ways to solve the problem. One is to build more and wider roads to make the public highways less crowded and speed up the flow of traffic. The other is to expand the number of public bus routes, so that more people can be transported and fewer people will have to travel by car or bicycle.
However, each of these solutions brings problems with it. The former may occupy too much land that could be used for farms or houses; the latter may cause inconvenience for long periods in bus lines. I think the best answer to the problem of heavy traffic is a combination of the two: build more roads in places where land is less useful, and at the same time increase the number of public bus routes.

（三）谚语警句型 13. Haste Makes Waste
A famous saying goes “Haste makes waste”, which means that one should do everything step by step. Even simple operations can easily be spoiled if we rush to complete them, neglecting important stages in the process. One should make full preparations before beginning any task.
Taking a look around, we can find examples too numerous to list. The best illustration might be English study. Without a good command of pronunciation, we can never hope to speak in an understandable way. Similarly, if we do not learn to spell properly and to acquire a basic grasp of grammar, we will never succeed in writing good compositions.
(或Actually, history abounds with examples of haste making waste. A well-known Chinese fable goes that a farm tried to help the shoots grow by pulling them upward, only to find that they died soon. Another case in point is the so-called Great Leap Forward movement in China in 1950’s and 1960’s. At that time, the Chinese people were so eager to develop their economy that they took some improper measures, only to hinder the expansion of economy.)
