主谓一致的常见规则 (一) 主谓一致三原则 1 . 语法一致原则:主语和谓语必须在人称和数的变化上保持一致,即主语为单数形式,谓语动词用单数形式;主语为复数形式,谓语动词也用复数形式. E.g. Sue is studying at a very famous university. Tom and Jack are twins. 2. 意义一致原则:谓语的单复数不是由主语的单复数形式决定的,而是以主语的意义为准,如 people, police, cattle 等用复数和 news, politics, physics, maths 等用单数单词. E.g. The police protect the people from being attacked. He says that politics is the art of class struggle. Bad news travels quickly. 3. 就近一致原则:句子有多个并列主语,如连词 or, either...or..., neither...nor..., not only...but also..., not...but... 等连接的并列主语,谓语的单复数形式取决于最靠近它的词语. E.g. Either the players or the coach is responsible for the defeat. Not only you but also I am planning to go camping. Neither you nor he is wrong. / Neither he nor you are wrong. 4. (二)主谓一致常见规则 1. 由 family, team, class, committee, crowd, enemy, group, public, party 等集体名词作主语时,如果作一个整体看待,谓语动词用单数形式;如果强调其成员,谓语动词用复数形式. E.g. His family is a big one. His family are all fond of football. 2. people, police, cattle 等集体名词,只当复数看待,谓语动词必须用复数. E.g. Many people have come already. The cattle are grazing in the field. 3. sheep, deer, fish, works( 工厂 ),means( 方法 ) 等单、复数同形的名词作主语时谓语动词应根据意义来决定单、复数形式。 E.g. A sheep is eating grass under the tree. A flock of sheep are grazing now. 4. the barber’s, the Smiths’, the teacher’s 等名词所有格之后的名词被省略,一般表示商店、住宅等,作主语时,谓语动词一般用单数。 E.g. My aunt’s is on the second floor. The doctor’s is at the corner of the street. 5. 表示时间、距离、度量、金钱等名词作主语时,常常根据意义一致的原则,把这些复数名词看作一个整体,谓语用单数形式。 E.g. Three miles seems like a long walk to me. Twenty years in prison was the penalty he had to pay. 6. each, every, no 等不定代词所修饰的名词即使以 and 或逗号连接成多个主语时,谓语动词仍用单数形式。第二个 each/every 有时可省略。 every ...and every..., each...and each..., no..and no... 用单数 E.g. No teacher and no student was absent from the meeting. Each man and (each) woman is asked to help. Every flower and every bush is to be cut down. 7. 若主语中有 more than one 或 many a ,尽管从意义上看表示复数,但它的谓语动词仍用单数形式。 E.g. Many a man has given his life for the cause of revolution. More than one problem has been solved. [ 注 ] “more +复数名词+ than one” 当主语时,谓语用复数形式。 E.g. More persons than one come to help us. More books than one were bought last week. 8. shoes, trousers, glasses, gloves 等表示成双成对的名词作主语时,谓语通常用复数形式;如果这些名词前有 a pair of ,谓语动词一般用单数形式。 E.g. My shoes are worn out. A pair of glasses is on the desk. 9. 主语中有 all, half( 一半 ) , most( 多数,大部分 ) , a lot of, lots of, plenty of, the rest( 余下的 ), the remainder( 剩余的 ) 等以及 “ 分数或百分数 + 名词 ” 用于主语时,其单、复数取决于连用的名词,名词为单数时,谓语也用单数;名词用复数时,谓语也用复数。 E.g. Half of the students are boys. The rest of the bicycles are on sale today. Most of the students are from Nanjing. Three
表示某国人时,动词用复数,这时与冠词 the 连用。E.g.Chinese is difficult to learn.The Chinese are very hard-working.21. 单个的动词的 ing 形式或不定式作主语时,谓语动词用单数形式。 E.g. To listen to music is my...
