一般情况下，两者可以互换。如：He started learning /to learn English when he was only three. 他在只有三岁的时候就开始学习英语了。但在下列三种情况下，只能用start to do sth.(1)当主语是物而不是人时。如：The ice started to melt. 冰开始融化。 （2）当start用于进行时态时。如:She is starting to cook the dinner. 她开始做饭（3）当start后面的非谓语动词指心理状态或精神活动（即表示想法、 意见等的词，如think, realize, wonder, understand等）时。如：She started to wonder who had done it. 她开始想是谁做了这件事。
