主謂一致考點(diǎn) 語法一致原則

考點(diǎn)1 語法一致原則

所謂“語法一致原則”即謂語動(dòng)詞和主語在單復(fù)數(shù)形式上保持一致。也就是說，如果主語為復(fù)數(shù)，謂語動(dòng)詞（在一般現(xiàn)在時(shí)中）用動(dòng)詞原形，若謂語中含有be動(dòng)詞，則用其復(fù)數(shù)are或were，若謂語中含有助動(dòng)詞have，則不應(yīng)使用其單數(shù)形式has，反之，如果主語為單數(shù)，謂語動(dòng)詞（在一般現(xiàn)在時(shí)中）用第三人稱單數(shù)形式，或根據(jù)時(shí)態(tài)選用單數(shù)形式的be動(dòng)詞am, is或was，助動(dòng)詞選用has。

由as well as, with, along with, like, together with, rather than, except, but, including, accompanied by, plus, besides, in addition to, no less than等引起的結(jié)構(gòu)跟在主語后面，不能看作并列主語，該主語不受這些短語引導(dǎo)的插入語的影響，主語如果是單數(shù)，其謂語動(dòng)詞仍然用單數(shù)形式，主語為復(fù)數(shù)，謂語動(dòng)詞使用復(fù)數(shù)形式。
