動詞不定式考點透視

動詞不定式是動詞的一種非謂語形式，沒有人稱和數的變化，不能單獨作句子的謂語。其構成形式為“to + 動詞原形”，to為動詞不定式的符號，本身無意義。動詞不定式具有兩大特點：

A. 具有動詞的特點，因此，后面可以跟表語、賓語或狀語，構成動詞不定式短語。

B. 具有名詞、形容詞或副詞的特點，可以在句子中用作主語、賓語、賓語補足語、狀語、定語、表語等。

以下對不定式的熱點考點做簡要的總結和分析，供同學們復習時參考。

[簡析] 動詞不定式作主語時，可以直接放在謂語動詞前面的主語位置，也可以用先行詞it作形式主語，而將真正的主語(不定式)置于后面。常見的句式有：⑴It takes sb. some time to do sth. ；⑵It’s + adj. + (of sb.) to do sth. ；⑶It’s + adj. (for sb.) to do sth. 。句式⑵中常用nice， kind， clever， good， right， wrong， foolish， careless等形容詞與介詞of搭配，這些形容詞常表述不定式邏輯主語的屬性或品質；句式⑶中常用hard， difficult， easy， important等形容詞與介詞for搭配，表示不定式動作、行為的性質。
