[填空题]Computer science is not only a comparatively young field, but also one that has had to prove it is really science. Skeptics in academia would often say that after Alan Turing described the concept of the" universal machine" in the late 1930’s—he idea that a computer in theory could be made to do the work of any kind of calculating machine, including the human brain—all that remained to be clone was mere engineering.
The more generous perspective today is that decades of stunningly rapid advances in processing speed, storage and networking, along with the development of increasingly clever software, have brought computing into science, business and culture in ways that were barely imagined years ago. The quantitative changes delivered through smart engineering opened the door to qualitative changes.
Computing changes what can be seen, simulated and done. So in science, computing makes it possible to simulate climate change and unravel the human genome (基因组). In business,

[单项选择]
During the twentieth century there has been a great change in the lives of women. A woman marrying at the end of the nineteenth century would probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. (76) By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which chance and health made it unusual for her to get paid work.
