Question

_____ soldiers and doctors have been in Wenchuan to help the people there.

A．Thousand of	B．Two thousands
C．Thousands of	D．Many thousands of

Answer 1

C解析:
本题考查数词。数词hundred, thousand, million等后面跟of 时，要变复数。排除A。thousand前接具体数字时，后面不能跟of,也不用复数形式，排除B。前面没有数字，thousand用复数，且其后用of。Many thousands of后接名词时，名词前要加the或物主代词。
