高三英語重要知識點分析1
一、就近一致原則
1.由or，not only...but also...，neither...nor...，either...or...，whether...or...，not...but...等連接兩個或兩個以上的并列主語時，通常根據(jù)就近一致原則，謂語動詞要與離它最近的主語在數(shù)上保持一致。
Neither his parents nor I am able to persuade him to change his mind.
2.here/there引導一個句子而主語又不止一個時，通常根據(jù)就近原則，謂語動詞要與離它最近的主語在數(shù)上保持一致。
Here is a ruler，a few pencils and two copybooks.
二、意義一致原則
1.謂語動詞必須用單數(shù)的情況
(1)表示學科的名詞以及works(工廠)，news(消息)等作主語時，雖然本身為復數(shù)形式，但表示單數(shù)意義時，謂語動詞仍用單數(shù)。
Politics is his favorite subject.
(2)表示某些組織機構的名詞、書/報名、國名、地名等作主語時，雖然形式上是復數(shù)，但所表示的意義是單數(shù)，所以謂語動詞用單數(shù)。

2.謂語動詞必須用復數(shù)的情況
表示總稱意義的名詞，如people，police，public，cattle等作主語時，謂語動詞用復數(shù)。

3.謂語動詞的形式依據(jù)主語表示的意義而定
(1)集體名詞，如family，class，group，team，club，company，government，population等作主語時，謂語動詞的形式根據(jù)其在語境中表示的意義而定。當其表示集體意義，強調整體概念時，謂語動詞用單數(shù);當其表示集體中各個組成部分，強調個體概念時，謂語動詞用復數(shù)。
As far as I know，his family is not very large but the family are all music lovers.
(2)“the+形容詞/分詞”表示“一類人”時，謂語動詞用復數(shù)。
The poor were looked down upon in the old days.
三、語法一致原則
1.由and連接的兩個名詞作主語
(1)“a/the+名詞單數(shù)+and+名詞單數(shù)”表示一個人(雙重身份)，謂語動詞用單數(shù)。
The teacher and poet often gives lectures around the city.
(2)“a/the+名詞單數(shù)+and+a/the+名詞單數(shù)”表示兩個人，謂語動詞用復數(shù)。
The teacher and the poet have just arrived.
(3)“every+名詞單數(shù)+and+every+名詞單數(shù)”表示每一個人，謂語動詞用單數(shù)。

(4)通常由兩個部件組成的物品如：a knife and fork (一副刀叉)等作主語，謂語動詞用單數(shù)。

2.表示時間、數(shù)量、長度及價格的名詞，盡管有時是復數(shù)形式但常被看作是一個整體，謂語動詞用單數(shù)形式。
Is fifty pounds enough?
3.“分數(shù)/百分數(shù)+of+名詞”作主語時，謂語動詞的形式根據(jù)of后的名詞的形式來定，如果名詞是可數(shù)名詞復數(shù)，謂語動詞用復數(shù)形式;如果名詞是單數(shù)可數(shù)名詞或不可數(shù)名詞，謂語動詞用單數(shù)形式。
Two-thirds of the books are about science.
Only 30% of the work was done yesterday.
