Usually, there are two reasons to pursue scientific knowledge: for the
sake of the knowledge itself, and for the practical use of that knowledge.
Because this second aspect of science effects the lives of most people, (1)______
it is much more familiar than the first. Knowledge must be gained,
however, after it can be applied, and often the most important technological (2)______
advances arise from research pursued for its own sake.
Traditionally, new technology has concerned with the construction (3)______
of machines, structures, and tools in a relatively large scale. The (4)______
development of materials for building bridges, skyscrapers or highways
is an example of this, as it is the development of the internal-combustion (5)______
engine and the nuclear reactor. While such activities involve all sections
of the sciences, the overriding goal has been the same, that is, improve (6)______
the human condition by finding good ways to deal with the macroscopic (7)______
world.
Since World War n, the focus of technological activity underwent
a major change. While the old activities are still pursued, they have been
largely superseded by applications of technology at the microscopic level.
Instead of building large-scale structures and machines, modern-day
technology tends to concentrate on finding improving ways to transfer (8)______
information and to develop new materials by studying the way atoms come
together. The silicon chip and microelectronics typify this new technological
trend, as did the blossoming of genetic engineering. The trend can be (9)______
expected to continue for the foreseeable decades. (10)______
(2)
选项
答案
after—before
解析
逻辑关系连接词错误。“掌握知识”(knowledge must be gained)应该发生在“应用”(be applied)之前,而不是之后,故要改after为before。

乡下老家前面的空地,租给人家种桃花心木的树苗。树苗种下来后,植树人总是隔几天才来浇水。他来的天数并没有规则,有时三天,有时五天,有时十几天来一次。浇水的量也不一定,有时浇得多,有时浇得少。桃花心木有时就莫名地枯萎了,所以,他来的时候总会带几株树苗补种。
