理了三大原則之一的語法一致原則的相關(guān)知識點，快來看一下吧。 動詞不定式、動名詞或名詞性從句作主語時，謂語動詞用單數(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，謂語動詞用復(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，謂語動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. 語法一致原一致是指句中的謂語動詞和主語在人稱和數(shù)上保持一致。在做涉及主謂一致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，也應(yīng)以語法一致原則為主?？傊?，在語言實踐中，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。

主謂一致（Subject- Verb Agreement），指”人稱”和”數(shù)方面的一致關(guān)系.如: He is going abroad. They are playing football.　可分為:語法一致， 內(nèi)容一致， 就近一致.今天著重計解內(nèi)容一致的原則。 內(nèi)容一致原則: 1.主語中有all, half, most, the rest等, 以及”分數(shù)或百分數(shù)+名詞”做主語時,謂語動詞單復(fù)數(shù)取決于連用的名詞.如: The rest of the bikes are on sale today.????剩下的自行車， 今天出售。 60%of the apple was eaten

More than one student was late.???? 不只一個學(xué)生遲到 More persons than one come to help us. 不止一個人來幫助我們。 7.? none 做主語時，謂語動詞可用單數(shù)， 也可用復(fù)數(shù); 但在代表不可數(shù)的東西時總是看作單數(shù)，因而謂語動詞要用單數(shù). 如: None of us are （is） perfect.?? 人無完人。 None of this worries me.?? 這事一點不使我著急。 8. 名詞如: trousers， scissors， clothes， goods， glasses 等作主語時， 謂語動詞必須用復(fù)數(shù). 如: His clothes are good. 但這些名詞前若出現(xiàn) a pair of ， 謂語一般用單數(shù).如: A pair of glasses is on the desk. 桌上有一副眼鏡。 9. 形復(fù)意單名詞如:news ; 以ics 結(jié)尾的學(xué)科名稱如
