主 謂 一 致 概念：謂語動詞在人稱與數(shù)上必須同主語保持一致， 叫主謂一致。主謂一致 語法一致 意義一致 就近 一致 句子的主語是單數(shù)形式，謂語動詞要用單數(shù)形式； 主語是復(fù)數(shù)形式，謂語動詞用復(fù)數(shù)形式。 如： A sheep eats grass. H e is a student. She likes English. Sheep eat grass. We are students. They like English. I、語法一致 II、意義一致原則 即謂語動詞該用單數(shù)還是復(fù)數(shù)取決于主語所表達(dá)的意義是單數(shù)還是復(fù)數(shù)。 如： The Chinese are hard-working 中國人是勤勞的。 1、動詞不定式、動名詞，從句或不可數(shù)名詞做主語， 謂語動詞用單數(shù)。 如：Listening to the tapes is helpful to our English study .2、表示時(shí)間、距離、價(jià)格、重量、數(shù)目、數(shù)學(xué)運(yùn)算等的詞 或短語做主語時(shí)，表示整體概念，謂語動詞用單數(shù)。 如：Ten years has passed. 10 kilometers is a long way for him . H e is too tired .3、由and ，bothand連接的兩個(gè)名詞做主語， 表示兩個(gè)不同的人或物時(shí)(每個(gè)名詞前各有冠詞，謂語動詞用復(fù)數(shù)。 指同一個(gè)人或物時(shí)（此時(shí)第二個(gè)名詞前沒有冠詞），謂語動詞用單數(shù)。 如：The painter and the writer have come to our school. ( 畫家和作家，兩個(gè)人) The painter and writer has come to our school . （畫家兼作家，同一個(gè)人） 5、主語是單數(shù)， 后面跟著as well as, no less than, rather than, but, besides, except, with, together with, along with , not , including, like 等再接一個(gè)名詞時(shí)， 謂語不受后一個(gè)名詞的影響， 仍然用單數(shù)。如果第一個(gè)名詞是復(fù)數(shù)，后再接這些詞再加一個(gè)名詞，謂語用復(fù)數(shù)。也就是說，謂語要與第一個(gè)名詞保持一致。Jack, as well as his parents, goes to see his grandpa every week.A woman with a baby in her hands was seen coming from the corner of the street. 4、不定代詞（somebody, someone, something, anybody, anyone, anything, everybody, everyone, everything , nobody, no one, nothing, each , every） 做主語時(shí)， 謂語動詞用單數(shù)。 如：Lucy, someone is waiting for you at the gate . Is everyone here? 6. 集體名詞：army, class, enemy, family, government, group, team., company, crew 等作主語，謂語動詞可用單數(shù)，也可用復(fù)數(shù)。如果主語作為一個(gè)整體看，謂語用單數(shù)；如果作為其中的成員（個(gè)體）看，謂語用復(fù)數(shù)。 The family are watching TV now. 他們一家人正在看電視。My family is a happy one. 我的家庭是一個(gè)幸福的家庭。 Class One is a very good class . Now Class One are having a basketball match.7. 主語是youth, police, people, clothes, public 等表示復(fù)數(shù)的（集體）名詞做主語，謂語用復(fù)數(shù)。而表示成雙成對的名詞，如gloves, shoes, glasses, scissors, trousers等詞后，謂語用復(fù)數(shù)，但用a pair of, this pair of, that pair of 加這些詞，謂語用單數(shù)。 Where are my shoes? This pair of shoes is not mine. 8. the rest of, a part of, a lot of , lots of., plenty of, half of, some of, most of, 百分比以及分?jǐn)?shù)+名詞作主語，若名詞為不可數(shù)名詞，謂語用單數(shù)，若名詞為可數(shù)名詞時(shí)，謂語用復(fù)數(shù)。 9. the + 形容詞表示一類人時(shí)，謂語動詞用復(fù)數(shù)形式。 如：The old are taken good care of in this old peoples house . 10. the + 姓氏的復(fù)數(shù)，表一家人或夫婦兩人,謂語動詞用復(fù)數(shù)。 如：The G reens are going to G ermany next week.11. news（新聞），politics（政治），maths（數(shù)學(xué)）， physics（物理）等詞，雖然形式上是以s結(jié)尾， 但表示的意義是單數(shù)，故謂語動詞要用單數(shù)形式。 相反，people，police等詞形式上是單數(shù)形式， 但表示復(fù)數(shù)意義，謂語動詞要用復(fù)數(shù)形式。如： Maths is my favourite subject數(shù)學(xué)是我最喜歡的學(xué)科。 12 the number of +（名詞復(fù)數(shù)） “的數(shù)量” 謂語用單數(shù) The number of the students in our school is over 2,000. 我們學(xué)校的人數(shù)是兩千多。 a number of +（名詞復(fù)數(shù)）“許多，大量”， 謂語用復(fù)數(shù) A number of students are from the country. III 就近一致原則： or, eitheror not onlybut also notbut 連接兩個(gè)名詞或代詞作主語，謂語要與最靠近謂語的那個(gè)名詞或代詞保持一致 There be 句型,謂語要與最靠近be的那個(gè)名詞或代詞保 持一致 H ere be 句型,謂語要與最靠近be的那個(gè)名詞或代詞保持一致 There is a book and two pens on the table.
