英語中主謂一致是指句中的謂語動(dòng)詞和主語在人稱和數(shù)上保持一致。在做涉及主謂一致的練習(xí)時(shí)，同學(xué)們有時(shí)會(huì)覺得顧此失彼。究其原因，往往是沒有把握住主語的真正內(nèi)涵，考慮不周全。今天小編為大家整理了三大原則之一的語法一致原則的相關(guān)知識(shí)點(diǎn)，快來看一下吧。

動(dòng)詞不定式、動(dòng)名詞或名詞性從句作主語時(shí)，謂語動(dòng)詞用單數(shù)形式。如:

To be an honest person is not easy.

Smoking does harm to health.

What he believes is not true.

由and或both.?and連接的名詞作主語時(shí)，謂語動(dòng)詞用復(fù)數(shù)形式。如:

The red coat?and the white coat?are very beautiful.

主語后面有as well as, together?with, along with, but, like, except, including等非并列連接性短語時(shí)，謂語動(dòng)詞要和主語在人稱和數(shù)上保持一致。

He as well as?me is responsible for this thing.

I, together?with?my sister, pan to have a picnic.

No one except him?agrees with this plan.

在倒裝句中, 謂語動(dòng)詞的數(shù)應(yīng)與其后的主語保持一致。如:

On the desk is a red pen.

Such are the facts.

語法一致原則在主謂一致中占有很大的比重，當(dāng)三種原則發(fā)生沖突時(shí)，也應(yīng)以語法一致原則為主?？傊?，在語言實(shí)踐中，我們不僅要記住一般的語法規(guī)則，更要把握好有些名詞的內(nèi)在涵義，才能做好有關(guān)主謂一致的題目。
