题型:不详难度:来源:
They are very grateful _______ us _______ them so much help.
A.to, to giveB.of, to giveC.for, giveD.to, for giving

答案
D
解析

试题分析:to到,向;for为了,对于。句意:因为给了他们如此多的帮助,他们对我们非常感激。结合语境可知前一空用介词to表示感激的对象,后一空有介词for表示感激的原因,故选D。
点评:英语介词的一个特点是一词多义,并且介词间语义交叉现象很多,习惯用法也很多,有时很难从词义上区分开来。故学习中要注意不断总结,熟记一些介词和动词的固定搭配用法及习惯用法,是完成此类问题的捷径。
