上面例子中主要行為動詞后面的動詞都采用了“t + 動詞原形”的結(jié)構(gòu),我們把這種結(jié)構(gòu)稱為動詞不定式(有時可以不帶t)。當(dāng)句子中已經(jīng)有謂語動詞,而我們又要表達不止一個動作概念時,其余的動詞可以使用非謂語形式表達。動詞不定式就是動詞的一種非謂語形式,其基本形式是“t+動詞原形”,否定形式為 “nt t+動詞原形”。

有些動詞既可跟不定式作賓語,也可跟動名詞作賓語,但含義不同:frget t d sth. 忘記要做某事frget ding sth. 忘記曾經(jīng)做過某事stp t d sth. 停下來去做某事 stp ding sth. 停止做某事g n t d sth. 繼續(xù)做另一件事g n ding sth. 繼續(xù)做原來在做的事need t d sth. 需要做某事need ding sth. 需要被做
