同等學(xué)力英語語法：主謂一致關(guān)系

主謂一致關(guān)系

英語中，主語和謂語在數(shù)、性和格上應(yīng)該保持一致，但在實際應(yīng)用中很容易被忽視，尤其是主語和謂語之間出現(xiàn)插入語，故考試中經(jīng)?？嫉街髦^一致。除了以上特殊名詞謂語有特殊要求外，現(xiàn)將主謂一致的考點歸納如下：

(1) 復(fù)數(shù)原則：兩個或者兩個以上的名詞由and連接做主語時;主語由both ...

and ... 連接時，謂語動詞用復(fù)數(shù)。

Baseball and swimming are usually summer sports. 棒球和游泳通常都是夏季的運動項目。

Both bread and butter are sold in that grocery. 那個雜貨店既賣面包，也賣黃油。

(2) 就近原則： 由 either ... or ...;neither ... nor ...;not only...but also...;...or ...;there be ...等引導(dǎo)的主語，謂語動詞的單復(fù)數(shù)取決于最靠近動詞的名詞的單復(fù)數(shù)。

Not only the students but also their teacher is invited to attend the party. 受邀參加晚會的不僅有學(xué)生而且有教師。

(3) 就遠(yuǎn)原則：主語，+ as well as + 另一個主語，謂語動詞的單復(fù)數(shù)取決于第一個主語的名詞的單復(fù)數(shù)。

My mother，as well as my two brothers，has a key to the office.

我母親，還有我的兩個哥哥都有一把辦公室的鑰匙。

適用于同樣規(guī)定的其他結(jié)構(gòu)：

with...;together with...;along with...;including...;in addition to...;besides...;except...;as much as...;accompanied by ...;rather than...等。

(4) 表示時間、距離、價值、量度的復(fù)數(shù)名詞做主語時謂語動詞用單數(shù)。

One hundred dollars is a large sum for the poor. 對于窮人來說，100美元是個不小的數(shù)目。

Twenty days has passed since I met her last time. 自從我上次見到她到現(xiàn)在已經(jīng)過去二十天。( twenty days 這里不做整體看待，故謂語動詞用復(fù)數(shù))

(5) and連接兩個名詞表示一個概念做主語時，謂語用單數(shù);若表示的是多個不同的概念時，謂語動詞用復(fù)數(shù)。

War and peace is a constant theme in literature. 戰(zhàn)爭與和平是文學(xué)中永恒的主題。(War and peace是一對概念，看做一個主題)

(7) many a，more than one + 單數(shù)可數(shù)名詞，盡管表示復(fù)數(shù)意義，謂語仍用單數(shù)。
