Question

关于非谓语动词的问题　1) I can't imagine ___that with them.为什么用doing而不用

Answer 1

1）imagine doing sth.是固定搭配

2）make sb.do sth.

be being done

以上的都是固定搭配.2中应该为be being caught,但be省略了

3）what 相当于先行词＋that

如果不用what ,应该为 the boy had no choice but to do the thing that his mother had told him.

另外,have no choice but to do sth.是固定搭配

4)keep sb.doing 是固定用法

5）shut在句中是过去分词,keep sth.done 句意为：他无法对所有的这些视而不见

我觉得你对一些固定的词组并不熟悉,所以建议你以后多背些常见的词组,我是学英语的,对英语比较感兴趣,
