Science Fiction
1 Amongst the most popular books being written today are those which are usually classified as science fiction.Hundreds of titles are published every year and are read by all kinds of people.Furthermore,some of the most successful films of recent years have been based on science fiction stories.
2 It is often thought that science fiction is a fairly new development in literature,but its ancestors can be found in books written hundreds of years ago.These books were often concerned with the presentation of some form of ideal society,a theme which is still often found in modern stories.
3 Most of the classics of science fiction,however,have been written within the last hundred years. Books by writers such as Jules Verne and H.G.Wells,to mention just two well-known authors,have been translated into many languages.

“New Towns" Plans

The plan of building"New Towns"to absorb growth is frequently considered a cure-all for urban problems. It is erroneously（错误地）assumed that if new residents can be diverted from existing centers,the present urban situation at least will get no worse.It is further and equally erroneously assumed that since European New Towns have been financially and socially successful,we can expect the same sorts of resorts in the United States.
Present planning,thinking,and legislation will not produce the kinds of New Town that have been successful abroad.It will multiply suburbs or encourage development in areas where land is cheap and construction profitable rather than where New Towns are genuinely needed.
Such ill-considered projects not only will fail to relieve pressures on existing cities but will,in fact,tend to weaken those cities further by drawing away high-income citizens and increasing the concentration of low-income groups that are unable to provide tax income.The remaining taxpayers, accordingly,will face increasing burdens,and industry and commerce will seek escape. Unfortunately,this mechanism is already at work in some metropolitan areas.
The promoters of New Towns so far in the United States have been developers,builders,and financial institutions.The main interest of these promoters is economic gain.Furthermore,federal regulations designed to promote the New Town idea do not consider social needs as the European New Town plans do.In fact,our regulations specify virtually all the ingredients of the typical suburban community,with a bit of political rhetoric thrown in.
A workable American New Town formula should be established as firmly here as the national formula was in Britain.All possible social and governmental innovation as well as financial factors should be clearly stated,and both incentives and penalties should be provided to ensure that the
objectives are pursued.If such a policy is developed,then the New Town approach can play an important role in alleviating America's urban problems.

Which of the following statements about European New Towns is NOT true?
A:They have been both financially and socially successful.
B:They have relieved the pressures on big cities.
C:The basic aim of building new towns is economic gain.
D:All social and governmental problems have been taken into account.
