有些動詞后接賓語時,既可接不定式,又可接動名詞,但有區(qū)別.如
1.like to do “喜歡做某事”,指一次性動作.如 I like to swim in this river now.
like doing “喜歡做某事”,指習(xí)慣性動作.如 I like swimming.
類似的還有：dislike to do / doing (“不喜歡做某事”),hate to do / doing (“討厭做某事”),
love to do / doing (“熱愛做某事”),prefer to do / doing (“更喜歡做某事”).

3.forget to do “忘了要去做某事” 如 They always forget to have lunch when they are busy.

8.begin to do與begin doing 都譯作“開始做某事”,二者可以混用.但是begin doing更強(qiáng)調(diào)動作不但開始,而且一直持續(xù)下去.如 The baby began crying hard.
而在下類情況下只用begin to do,不用begin doing：
○1當(dāng)主語是物時.如 It began to snow.
○2當(dāng)begin用進(jìn)行時的時候.如 The train is beginning to leave.
○3當(dāng)begin后接表示心理活動的動詞(如think,understand,know)時.如 She began to understand her parents.
注：begin的用法完全適用于start.
9.go on to do “繼續(xù)做某事”,指做不同的事.
如 After reading English,she went on to learn math.
go on doing “繼續(xù)做某事”,指做同一件事,相當(dāng)于_go on with sth .
