Question

帮忙分析一个英语句子，谢谢！

young people nowadays could not imagine what difficulty their fathers had___for a better life for their children. 四个选项：1 to strive 2 striven 3 striving 4 to be striving.答案选的是第三，为什么呢？我知道had不跟后面连的，可是为什么这里用ing而不是用过去式做形容词呢？
好吧·····貌似选项也没有过去式。那如果有strived,可以选这个吗？看着第一个好像也对啊

Answer 1

额，楼上的解释还真是。。。。
把句子还原。their fathers had difficulty (in) striving for a better life for their children.
这里imagine纯属路过而已。。。。

Answer 2

应该是had sb doing，因为这里有一个what的宾语从句，所以这里是把their fathers提前了。
也就是说是让他们的父亲遭受困难。
had done是指过去完成时，是过去的过去已经完成的。
谢谢！望采纳！

Answer 3

what引导的为一个宾语从句(做imagine的宾语),也为插入语，所以后面跟的非谓语动词与imagine有关，与had无关。imagine后面的非谓语动词用现在分词充当，不能用过去分词

Answer 4

their fathers had difficulty+ doing sth
这里考察句型have difficulty (in)doing sth

Answer 5

看了犬夜叉的回答好像顿悟了！应该就是fathers had difficulty（in）striving for life（顺便说一句我好喜欢Inuyasha！！！）
