问题补充：
The big flood last week affected(影响) people’s lives, and them died.
A. thousands of; two hundred
B. thousands of; two hundred of
C. two thousand; two hundred
D. two thousands; two hundreds
答案：
A. thousands of; two hundred
(答案→)B. thousands of; two hundred of
C. two thousand; two hundred
D. two thousands; two hundreds
解析：句意：上周的大洪水影响了数千人的生活，其中两百人丧失生命。thousands of +名词复数；two hundred of +范围；表示具体数字，hundred、thousand、million这类词不用复数形式，也不与of连用，可直接修饰名词，但表示概数时，必须使用复数形式并且与of连用，才可修饰名词。所以选B。
