SAT 語(yǔ)法中主謂一致的三大原則

（一）語(yǔ)法一致原則
　　用作主語(yǔ)的名詞詞組中心詞和謂語(yǔ)動(dòng)詞在單、復(fù)數(shù)形式上的一致，就是語(yǔ)法一致。也就是說(shuō)，如果名詞中心詞是單數(shù)，動(dòng)詞用單數(shù)形式；如果名詞中心詞是復(fù)數(shù)，動(dòng)詞用復(fù)數(shù)形式。例如：
This table is a genuine antique.
　　Both parties have their own advantages.
　　Her job has something to do with computers.
　　She wants to go home.
　　They are divorcing each other.
　　Mary was watching herself in the mirror.
　　The bird built a nest.
　　Susan comes home every week-end.

（二）意義一致原則
　　有時(shí)，主語(yǔ)和謂語(yǔ)動(dòng)詞的一致關(guān)系取決于主語(yǔ)的單、復(fù)數(shù)意義，而不是語(yǔ)法上的單、復(fù)數(shù)形式，這樣的一致關(guān)系就是意義一致。例如：
　　Democratic government gradually take the place of an all-powerful monarchy.
　　A barracks was attacked by the guerrilla.
　　Mumps is a kind of infectious disease.
　　The United States is a developed country.
　　It is the remains of a ruined palace.
　　The archives was lost.
　　This pair of trousers costs fifty dollars.

（三）就近原則
　　有時(shí)，謂語(yǔ)動(dòng)詞的單、復(fù)數(shù)形式?jīng)Q定于最靠近它的詞語(yǔ)。 例如：
　　Either my grandsons or their father is coming.
　　No one except his daughters agree with him.
　　Mary and her sisters are baking a cake.
　　Neither Richard nor I am going.

二、以集合名詞做主語(yǔ)的主謂一致問(wèn)題
　　有些集合名詞，committee,council,crew,crowd,family,gang,government,group,mob,staff,team, union等，在意義上是復(fù)數(shù)，但在語(yǔ)法形式上是單數(shù)，這類名詞作主語(yǔ)的主謂一致問(wèn)題往往遵循“語(yǔ)法一致”或“意義一致”原則。例如：
　　The committee has/have decided to dismiss him.
　　A council of elders governs the tribe.
　　The present government is trying to control inflation.
　　The school staff are expected to supervise school meals.

（一）通常作復(fù)數(shù)的集體名詞
　　包括police,people, cattle, militia, vermin等，這些集體名詞通常用作復(fù)數(shù)。 例如：
　　The British police have only very limited powers.
　　The militia were called out to guard the borderland.
　　It seems the cattle on the sides of the dikes were the only living creatures in these desolate surroundings.

（二）通常作不可數(shù)名詞的集體名詞
　　通常作不可數(shù)名詞的集體名詞，包括poultry,foliage，machinery, equipment,furniture, merchandise等,這類名詞后的動(dòng)詞用單數(shù)形式。 例如：
　　Poultry is expensive at this time of year. That green foliage was restful.
　　The merchandise has arrived undamaged.
　　All the machinery in the factory is made in China.
　　The suite of furniture he bought was of contemporary style.
　　The equipment of the photographic studio was expensive.

（三）可作單數(shù)也可作復(fù)數(shù)的集體名詞
　　可作單數(shù)也可作復(fù)數(shù)的集體名詞,包括audience, committee, crew, family, government,jury等。 例如：
　　The audience was/were enthusiastic on the opening night of the play.
　　The committee has/have decided to dismiss him.
　　The jury is/are about to announce the winners.
　　The government has/have discussed the matter for a long time.

三、a committee, etc of +復(fù)數(shù)名詞的主謂一致問(wèn)題
　　如果主語(yǔ)是由a committee of /a panel of /a (the) board of +復(fù)數(shù)名詞構(gòu)成，隨后的動(dòng)詞通常用單數(shù)。 例如：
　　A committee of twelve men is to discuss the matter.
　　A panel of experts has considered the situation.
　　The board of managers is responsible for the firm.

四、以-s結(jié)尾的名詞作主語(yǔ)的主謂一致問(wèn)題
　　英語(yǔ)可數(shù)名詞的規(guī)則復(fù)數(shù)形式是在詞尾加-s或-es，但是有一些以-s結(jié)尾的名詞并不是可數(shù)名詞。它們用法多樣，造成了實(shí)際使用上的困難，以下詳述了以-s結(jié)尾的名詞作主語(yǔ)的主謂一致問(wèn)題。
　　（一）以-s結(jié)尾的疾病名稱作主語(yǔ)的主謂一致問(wèn)題

　　The United States was hit by the Great Depression in 1930s’.
　　In early January 1996 the Netherlands was hit by its worst storm since 1976.
　　但如果是群島、山脈、海峽、瀑布等地理名稱作主語(yǔ)，謂語(yǔ)動(dòng)詞用作復(fù)數(shù)。 例如：

　　The economics of the project are still at issue.

（五）其它以-s結(jié)尾的名詞的主謂一致問(wèn)題
