The first modern digital computers were developed in the 1940s for
military purposes that arose during World War II. These computers filled
entire rooms, and with rates of a few thousand calculations per second, they【M1】______
took hours to perform complex mathematical operations. In the 1970s, the
first personal computers were sold. Fitting on a desktop, they are【M2】______
exponentially faster and more powerful than the computers that had once
filled large rooms. They were also affordable to individual consumers, made【M3】______
it possible for many people to use them for personal, business, and academic
needs. By the mid-1990s, laptop computers able of millions of calculations【M4】______
per second had been developed. Currently, nearly half of American homes
have a personal computer, and businesses have come to rely on computers for
nearly every function.
Now that computers are small, powerful, cheap, and effect every part【M5】______
of our lives, the next step will be the formation of a network connecting all of
these computers to each another. On this network, which some people are【M6】______
calling the information highway, great changes take place every day. The
changes to society will be as revolutionary as those of the Industrial Age and
the Renaissance. Not only will people shop and conduct business through
their computers, but they will also engage with every type of human activity,【M7】______
from reading to simply hanging with friends. The increased level of【M8】______
communication made it possible by computer networks will bring many【M9】______
benefits in the areas of business, education, and social interaction, producing
widespread sharing of knowledge and wealth and the worldwide cultural renewal.【M10】______ [br] 【M2】
选项
答案
are—were
解析
时态错误。根据前文中的时间状语In the 1970s以及后文中出现的“…the computers that had once filled…”,可知该处应该使用的时态是一般过去时,故将are改为were。
