Question

Last month,part of Southeast Asia

was hit by floods from _____ effects the people are still suffering.
A.that
B.whose
C.those
D.what
麻烦解释一下．

Answer 1

正确答案是B.

解释:这是考查定语从句的连接词.
先行词是floods,把它放进定语从句中去,只能解释为:
the people are still suffering the floods' effects.
也就是说定语从句中所缺的词是"洪水的"这个所有格形式,而whose刚好起到此功能.它相当于the floods',即"洪水的",做effects的定语.

Answer 2

D.what
根据意思只能选that或者what（last month，部分Southeast Asia地区遭遇flood EFFECT的people仍旧在suffering。）。介词（from）后面不能用that。所以只剩what。
