一、主謂一致三原則

　　主謂一致是指謂語動(dòng)詞與主語在人稱和數(shù)上保持一致，主謂一致必須遵循三原則：語法一致原則，意義一致原則，就近一致原則。語法一致原則：指主語是單數(shù)形式，謂語動(dòng)詞用單數(shù)形式，主語是復(fù)數(shù)形式，謂語也用復(fù)數(shù)形式。例如：

　　Tom is a good student.

　　湯姆是個(gè)好學(xué)生。

　　They often play football on the playground.

　　他們經(jīng)常在操場(chǎng)上踢足球。 意義一致：指主語形式上為單數(shù)，但意義為復(fù)數(shù)，因此謂語動(dòng)詞用復(fù)數(shù)形式；或主語形式上為復(fù)數(shù)，但表示單數(shù)意義，這是謂語動(dòng)詞用單數(shù)形式。例如：

　　My family are having lunch now.

　　我們一家人現(xiàn)在正吃午飯。

　　Twenty dollars is too expensive for the book.

　　這本書20美元太貴了。 就近一致：指謂語動(dòng)詞用單數(shù)形式還是用復(fù)數(shù)形式，取決于最靠近他的主語。例如：

　　Not only the teacher but also his students like playing football.

　　不僅老師喜歡踢足球，而且他的學(xué)生也喜歡踢足球。

　　There is a pen and some books on the desk.

　　課桌上有一支鋼筆和一些書。

　　 二、 主謂一致�？碱}型

　　單數(shù)名詞(代詞)，不可數(shù)名詞作主語時(shí)，謂語用單數(shù)形式，復(fù)數(shù)名詞(代詞)作主語，謂語用復(fù)數(shù)形式。例如：

　　The desk is Tom’s.

　　這張桌子是湯姆的。

　　Some water is in the bottle.

　　一些水在瓶子里。

　　The students are playing football on the playground.

　　這些學(xué)生正在操場(chǎng)上踢足球。 many a+單數(shù)名詞作主語，意義雖為“許多”，但謂語要用單數(shù)形式。例如：

　　Many a student has been to Shanghai.

　　許多學(xué)生到過上海。 more than one+單數(shù)名詞作主語，謂語用單數(shù)。例如：

　　More than one student has ever been to Beijing.

　　不止一個(gè)學(xué)生曾經(jīng)去過北京。 表示時(shí)間，價(jià)格，重量，數(shù)目，長(zhǎng)度，數(shù)學(xué)運(yùn)算等的詞或短語作主語時(shí)，這些通常作一個(gè)整體概念，謂語用單數(shù)形式。例如：
