I'll do what I can to help you.
想請問知識大大們,為什麼上句句中要加上不定詞to呢?can後面不是使用原形V嗎?謝謝:)

✔ 最佳答案
I'll do "what I can (do)" to help you.
引號中的子句是當作動詞do的受詞的名詞子句。因為要避免動詞重複,而將子句的動詞省略,只留下助動詞can。
what是「帶先行詞的關係代名詞」,兼名詞子句的「受詞」。what = the thing that
to help you是「不定詞片語」,當作述部will do xxx的「修飾語」。不定詞是verbal(動狀詞)的一種,是由動詞(verb)衍生的詞類,但用法不同於動詞。

what I can-----------adv.clause +root verb="can" preceded by will do(=VO).
I'll do------------------omit object----SVO
-------do=aux.verb used before a verb (kill) for emphasis
------=do away with=phrasal verb=(kill)
to help you----------infinitive phrase as adverb phrase qualifying "do",no need root verb="can"

what I can是一個子句,to是跟在do後面的用法.
I'll do " ..." to help you.

what I can是一個受詞片語,類似插入句,當成do的受詞,do這個動詞後面要加一個to再
加一個動詞help.

I'll do what I can to help you
我將做我能做的事來幫助你。

I'll do what I can help you
我將做我能幫助你的事。

有沒有to,意思不太相同。

這句話是省略用法、还原全句I'll do what I can ( in order)to help you. 其中to help you不定詞片語当副詞修飾動詞do
