主謂一致的三個(gè)原則

1. 語(yǔ)法一致原則

該原則要求謂語(yǔ)動(dòng)詞必須與主語(yǔ)在語(yǔ)法形式上保持一致，即主語(yǔ)是單數(shù)形式，動(dòng)詞用單數(shù)形式，主語(yǔ)是復(fù)數(shù)形式，動(dòng)詞用復(fù)數(shù)形式：

Both my parents are doctors. 我的父母都是醫(yī)生。

The living-room walls are a light yellow. 客廳的墻是淡黃色。

The two factories are in the same locality. 兩家工廠都在同一個(gè)地區(qū)。

Her job is teaching French. 她的工作是教法語(yǔ)。

The location of the house is near the highway. 房子的地點(diǎn)靠近公路。

A large amount of damage was done in a short time. 短期內(nèi)造成大量損害。

2. 意義一致原則

有時(shí)候謂語(yǔ)動(dòng)詞的數(shù)取決于主語(yǔ)所表示的概念，而不是其語(yǔ)法形式：

This news is important for us. 這條消息對(duì)我們很重要。

Paris is among the largest cities in the would. 巴黎是世界上最大的城市之一。

The thesis was about a hundred and fifty pages long. 論文有一百五十頁(yè)長(zhǎng)。

Watch out! The police are coming. 當(dāng)心，警察來(lái)了。

Less people are going to university than usual. 現(xiàn)在上大學(xué)的人比平時(shí)少。

3. 就近原則

有時(shí)，謂語(yǔ)動(dòng)詞的數(shù)決定于主語(yǔ)中最靠近它的詞語(yǔ)：

Either you or I am wrong. 不是你錯(cuò)了就是我錯(cuò)了。

Neither the students nor the teacher is interested in it. 老師和學(xué)生對(duì)此都不感興趣。
