问题     Higher productivity is essential to the rising of living standards and to the declining prices of goods and services. But higher productivity may lead to fewer jobs.
    Early in the postwar era, analysts were worried that automation would take over manufacturing, throwing everyone out of work. That fear went unrealized for a generation, in part because robots and computers weren’t good at much. Today, near-automated manufacturing is becoming a reality.
    Newly built factories often require only a small part of the work force in the plants. Office technology, meanwhile, now allows a few to do what once required a large group of people.
    There may come a point when the gains from higher productivity pale before the job losses, But even if that point does not come, rapid technological change is causing anxiety about future employment: anxiety that makes it hard to appreciate and enjoy what productivity creates.
    Prosperity brings many other mixed blessings. Living standards keep rising, but so do cases of depression. Agricultural yields continue rising, yet that means fewer family farms are needed Biotechnology may allow us to live longer, but may leave us dependent on costly synthetic drugs. There, are many similar examples. Increasingly, western life suffers from the paradoxes (自相矛盾) of progress. Material circumstances keep improving, yet our quality of life may be no better as a result — especially in those cases, like food, where enough becomes too much.
The last paragraph mainly tells us that______.
选项 A、material benefits are what we need
B、prosperity is just one side of the same coin
C、the quality of life may be worse than before
D、western people are free from the paradoxes of progress
答案B
解析 该题为段落主旨题。最后一段的第一句话是本段的主题句“Prosperity brings many other mixed blessings。”。接下来整段都在讨论具体的利弊。选项A．material benefits are what we need不是这段讨论的主要内容，因为这段并没有论述我们多么需要物质利益，恰恰还讲了物质丰富带来的弊端。选项B表达的“繁荣只是事物利弊两面性的一个方面”则说明了本段的主题句。选项C．the quality of life may be worse than before与文章最后一段“…our quality of life may be no better”并不符合。选项D．western people are free from the paradoxes of progress与文章最后一段的说法“Increasingly, western life suffers from the paradoxes(自相矛盾)of progress．”正相反，所以也不正确。
