start to do sth与start doing的区别如下:
start doing 和start to do都是“开始做某事”的含义。
但在以下三种情况,常用start to do不用start doing的形式:
1、句子主语是物不是人的时候,后用start to do sth
2、当start用于进行时即starting时,后接to do sth.
例如:I was starting to get angry. 我开始发火了。
I am starting to cook the dinner. 我正要开始煮饭。
3、在 start 之后出现的动词涉及感情或思想(如 understand, realize等)时,只可用不定式。
例如:She started to understand what he really wanted. 她开始明白他真正想要什么。
She started to wonder why he was here. 她开始觉得奇怪为什么他会在这儿。
当我们谈论一项长期的或习惯性的活动时,用start doing形式的情形较多。
例如:How old were you when you first started playing the piano? 你最初弹钢琴的时候有多大?
比较 :She sat down at the piano and started to play. 她在钢琴前坐下开始弹了起来。
