Computers will develop more successfully because they enable us to fulfill tasks that
wasn’t able to undertake ever before
.
选项
A、couldn’t be undertaken
B、mustn’t have been undertaken
C、could never before have been undertaken
D、would never before have undertaken
答案
C
解析
tasks和undertake之间是被动关系,故排除D。本题要表达的是,本来过去可能是连做都不会开始做的任务,现在却可以完成了,C最符合这个意思,“could(not/never)have done”指“本可能(不)”,因此C正确。A只是简单的否定,没有“本…”这样的意味,若选A,则变成“完成不能去做的任务”,有逻辑的漏洞。mustn’t have…表示“肯定还没”,但题意表明现在“已开始做了”。
