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, 【S1】______
it is much more familiar than the first. Knowledge must be gained,
however, after it can be applied, and often the most important technological 【S2】_____
advances arise from research pursued for its own sake.
Traditionally, new technology has concerned with the construction 【S3】_____
of machines, structures, and tools in a relatively large scale. The 【S4】_____
development of materials for building bridges, skyscrapers or highways
is an example of this, as it is the development of the internal-combustion 【S5】_____
engine and the nuclear reactor. While such activities involve all sections
of the sciences, the overriding goal has been the same, that is, improve 【S6】_____
the human condition by finding good ways to deal with the macroscopic 【S7】_____
world.
Since World War II, 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largely superseded by applications of technology at the microscopic level.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 【S8】_____
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 【S9】_____
expected to continue for the foreseeable decades. 【S10】_____ [br] 【S3】
选项
答案
concerned—been concerned
解析
语法错误。由traditionally可知完成时态没有错误,但concern表达“涉及,有关”的意义时,是及物动词,这里需用到被动语态,故添加过去分词been。be concerned with意为“与……有关,涉及”。
