初中英語知識點總結(jié)：動詞不定式的10大考點例析

動詞不定式是初中英語的語法重點之一，也是每年中考英語試題的考點之一。它是動詞的一種非謂語形式，沒有人稱和數(shù)的變化，不能單獨作句子的謂語。其構(gòu)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：

1.具有動詞的特點，因此，后面可以跟表語、賓語或狀語，構(gòu)成動詞不定式短語。

2.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(bǔ)足語、狀語、定語、表語及同位語等。下面以近幾年全國部分省市的中考英語試題為例，對不定式的難點以及它在中考英語中的考查點，作一簡要的總結(jié)和分析，供同學(xué)們學(xué)習(xí)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：(1)It is +形容詞(of sb)to do sth.(2)It is +名詞(for sb)to do sth.(3)It takes sb some time to do sth.(4)It is +形容詞(for sb)to do sth.句式(1)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性質(zhì);句式(4)中常用hard， difficult， easy， important等形容詞，與介詞for搭配，表示不定式表示的動作、行為的性質(zhì)。

[簡析]在see， hear， watch， feel等感官動詞后面可接不帶to的不定式，也可接動詞的-ing形式作賓語補(bǔ)足語，用不定式表示動作的全過程(動作已結(jié)束)，用動詞的-ing形式表示動作正在進(jìn)行(動作尚未結(jié)束)。

九、動詞不定式的省略及其符號to的保留

1. Would you like to go to the cinema with us?

[簡析]在口語中，動詞不定式中的動詞或短語動詞在上下文中重復(fù)出現(xiàn)時，第二個動詞不定式可以省略，但是to不可省略。這種用法常見于"be glad to"，"would like (love) to"，"have to"等結(jié)構(gòu)中。

十、動詞不定式的被動式和其他形式

A. build B. builds C. to build D. to be built (青海省)

Key： D

[簡析]當(dāng)不定式的邏輯主語是不定式所表示的動作的承受者(賓語)時，用動詞不定式的被動式，即：to be +過去分詞;如果不定式所表示的動作發(fā)生在謂語動詞表示的動作之前，不定式用完成式，即：to have +過去分詞;如果不定式表示的動作和謂語動詞表示的動作同時發(fā)生，用不定式的進(jìn)行式，即：to be +現(xiàn)在分詞
