2013年英語(yǔ)六級(jí)語(yǔ)法講解大全（6）

　　五、非謂語(yǔ)動(dòng)詞(Non-finite Verb)

　　在英語(yǔ)中，不是用于句子謂語(yǔ)而是用于擔(dān)任其他語(yǔ)法功能的動(dòng)詞叫做非謂語(yǔ)動(dòng)詞，也稱作動(dòng)詞的非限定形式。

　　非謂語(yǔ)動(dòng)詞有三種形式：不定式(the Infinitive)、分詞(the Participle)和動(dòng)名詞(the Gerund)。

　　不定式

　　1. 構(gòu)成與形式

　　不定式由不定式符號(hào)“to + 動(dòng)詞原形”構(gòu)成(有時(shí)不帶to)。前面可以加某些疑問(wèn)代詞，如what, who, which, 或疑問(wèn)副詞，如when, where, why等，構(gòu)成特殊的不定式短語(yǔ)，如what to do next, how to get there等。

　　不定式形式有：

　　2. 用法

　　不定式不能單獨(dú)作謂語(yǔ)，沒(méi)有人稱和數(shù)的變化，具有名詞、形容詞和副詞的特征，而且還保留著動(dòng)詞的特征，因而可以有狀語(yǔ)修飾，如果是及物動(dòng)詞，還可以帶賓語(yǔ)，從而構(gòu)成不定式短語(yǔ)。不定式或不定式短語(yǔ)在句子中可以作主語(yǔ)、表語(yǔ)、賓語(yǔ)、定語(yǔ)、狀語(yǔ)、主語(yǔ)補(bǔ)足語(yǔ)和賓語(yǔ)補(bǔ)足語(yǔ)。

　　7) 作賓語(yǔ)補(bǔ)足語(yǔ)

　　They didn’t allow her to park the car in this street.

　　有一些動(dòng)詞后用作賓語(yǔ)補(bǔ)足語(yǔ)的不定式通常不帶to。這種動(dòng)詞有兩類(lèi)：一類(lèi)是感官動(dòng)詞，如feel, see, hear, watch, notice等;另一類(lèi)是使役動(dòng)詞，如make, let, have等，如：
