选择题
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
答案：D
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。
