题目

.Computers can do ______ work in a short time,but a man can not do ______ by himself
a great many…many c.much…a great deal
b.a great deal of…much d.many…a great many
请高手给个确切的答案,再讲下其中的语法知识,我将感激不尽!

答案

b
much 和 a great deal 都+ 不可数
但为什么选b,不选c
因为含义和语感
not do much 人类自己做不了这么多,只能做一点
如果 not do a great deal好像没这种说法,读着也别扭
