非谓语动词改成从句后动词形式会怎么变化？

Question

如题所述

Answer 1

其实很简单
非谓语动词就是分词，动名词，不定式他们的形式是doing、done，doing，to
do
一般一个句子最少有一个动词
那他就是谓语动词
有各种各样的时态
分词可以当形容词用，也就是定语
动名词顾名思义是名词，作主语，宾语
不定式，既可以作定语，也可以做主，宾
还是要结合语境分析 先把句子成分搞清楚。主谓宾定状补
定语从句和前面的先行词是修饰关系
宾语从句和前面的谓语动词是
动宾关系
状语从句和前面的谓语动词也是修饰关系

Answer 2

非谓语动词改为从句后，必须由原来的非谓语形式改为谓语形式，即必须在从句中作谓语。

they
