在大學(xué)英語(yǔ)四級(jí)測(cè)試的“詞匯與結(jié)構(gòu)”一題中，考查主語(yǔ)和謂語(yǔ)一致關(guān)系的試題居多。所以主謂一致是各類一致關(guān)系中應(yīng)該重點(diǎn)掌握的內(nèi)容。現(xiàn)代英語(yǔ)主謂一致大致要遵循以下三條原則：

　　1)語(yǔ)法一致原則。主語(yǔ)是單數(shù)，謂語(yǔ)動(dòng)詞用單數(shù)形式;主語(yǔ)是復(fù)數(shù)，謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式。

　　【例如】

　　My friend has no intention of going shopping with me.

　　My friends have no intention of going shopping with me.

　　2)意義一致原則。主語(yǔ)和謂語(yǔ)的一致不是由主語(yǔ)的語(yǔ)法形式來(lái)決定，而是由主語(yǔ)所表達(dá)的意義決定。

　　【例如】

　　The class are busying writing English passages.

　　The United States is a developed country which has advanced science and technology.

　　帶有復(fù)數(shù)詞尾的學(xué)科名稱、國(guó)家等在意義是表示單數(shù)概念，用單數(shù)動(dòng)詞。

　　3)就近原則。謂語(yǔ)動(dòng)詞的單、復(fù)數(shù)取決于最靠近它的主語(yǔ)。由either....or, neither....nor, not only....but also連接或由here, there等引導(dǎo)的句子，謂語(yǔ)動(dòng)詞遵循這一原則。

　　【例如】Neither my friends nor I was able to persuade him to accept our advice.

　　Either he or she has broken the window, for there is no one else there.

　　There is a teacher and fifty students in the classroom.
