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largely superseded by applications of technology at the microscopic level.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】______
【S9】
选项
答案
did—does
解析
时态错误。此句为as引导的方式状语从句,因而该句的主谓语应倒装;因前一分句中typify用一般现在时,故应改did为does,保持时态一致。
