问题补充：

Computers can do a lot of things nowadays, but more still need to be done by man.

A. a large amount of

B. a great deal

C. a good many of

D. a great many

答案：

A. a large amount of

B. a great deal

C. a good many of

(答案→)D. a great many

解析：考查短语辨析。a large amount of 许多的，大量的，后修饰不可数名词，a great deal 副词，非常，a good many of，of去掉后修饰棵树名词复数，a great many后修饰棵树名词复数。句意：现在电脑能做许多事情，但是许多事情更需要人来做。所以用a great many后省略了things，故选D。
