1. 不定式一般表示具体的、特定的行为；而-ing分词一般表示抽象的、一般的行为。
2. 在疑问句中，只能用动名词的复合结构作主语。
3.在某些句型中通常要用动名词短语作主语
4.一般说来，作主语和表语的非谓语动词形式应一致，即：或同时为不定式，或同时为-ing分词。
1. 主语：表示句子所要说明或描述的人或事物，
一般由 名词、代词
或相当于名词的词组或句子
充当，置于句首
++++希望你可以帮助你 被你采纳 我也可以加分哟 哈哈
补充：
若用动名词开头做主语，那么宾语也要用动名词形式。不定式也是。
To run is faster than to walk.
Running is faster than walking.
