help sb do sth是大家比较熟悉的结构,通常也可说成help sb to do sth,其意为 “帮助某人做某事”,两者常可通用——即其中的不定式符号to可以省略,也可以保留。如:
We helped her (to) find her things. 我们帮她找东西。
I helped him (to) repair his bike. 我帮他修自行车。
Mother helped me (to) do my homework. 妈妈帮助我做家庭作业。
Will you help me (to) choose myself a new coat? 请你帮我选件新大衣好吗?
Can anyone help me (to) fill in this tax form? 有谁能帮我填写税单吗?
When she fell, a friend rushed to help her (to) get up. 她摔倒时,一个朋友冲上前把她扶起来。
1、释义不同:help doing与can't连用,意为忍不住/情不自禁去做某事;help to do 意为帮助、援助。
2、用法不同:help (to) do sth实际上有时候to是省略掉的,用作help do sth。help + doing 是与can't一起用的,用作can't help doing sth。容易与can't help doing混淆的是can't help to do,译为不能帮助做某事。
3、例句:
(1)I can't lift this box — will you help me please? 译文:我举不动这个箱子,请你帮我一下好吗?
(2)I couldn't help crying.译文:我忍不住哭了。
(3)He can't help to do housework,for he is busy. 他由于忙不能帮助干家务。
