1、英语语法 主谓一致 主谓一致 Subject-verb Concord“一致”（concord或agreement）指句子成分之间或词语之间在语法形式上的协调关系。“主谓一致”指的是英语句子的谓语动词（Predicate Verb)与其主语(Subject)在数上必须保持一致。2.1指导原则英语中的主谓一致主要遵循三个原则:语法一致语法一致原则,意义一意义一致致原则和就近原则就近原则。一.语法一致原则（Grammatical Concord)主语和谓语通常是从语法形式上取得一致，即主语是单数形式，谓语动词也取单数形式；主语是复数形式，谓语动词也采用复数形式。（1）不可数名词，动名词，不定式，从

2、句等作主语时，谓语通常用单数。Much effort is wasted.To eat well _(be)all he ask.（2）不定代词every,each,each one,each of,everybody,everything,many a+名词名词 作主语时，谓语动词用单数形式。Many a ship has been damaged in the storm.（常考）is(3)复数名词、代词作主语，谓语动词一般用复数形式All the students _clever.（are）(4)如主语后面跟有with,together with,as well as,as much a

3、s,no less than,more than,rather than,except,in addition to 等引导的短语，谓语动词取决于主语本身的形式。His brother rather than his parents is to blame.Bill,together with his sisters,was hurt in the accident.二.意义一致原则意义一致原则（Notional Concord）即谓语动词的单复数形式取决于主语所表达的内容在含义是单数意义还是复数意义。如：The crowd were running for their lives.其主语形式

4、虽为单数，但意义为复数，谓语动词为复数。三.就近原则就近原则（Principle of Proximity）谓语动词该用单数还是复数形式，取决于最邻近它的名词、代词或其它词的数。（1）谓语动词的单复数形式取决于最靠近它的词语。如用连词or,eitheror,neithernor,not only,but also等连接的并列主语，如果一个是单数，一个是复数，谓语动词与靠近它的主语一致。如：Either your students or Mr.Wang knows this.比较：Either Mr.Wang or your students know this.（2）当主语表示确定数量的名词词

5、组并由“one in/one out of+复数名词”构成，在正式语体中，动词用单数；在非正式语体中，动词也可按“就近原则”用复数。One in ten students has failed the exam.比较：One in ten students have failed the exam.2.2以-s为结尾的名词作主语的主谓一致问题（一）以-s结尾的疾病名称作主语的主谓一致问题 如：arthritis,:rrats（关节炎）bronchitis,brkats（肺炎）measles（麻疹）diabetes（糖尿病）,mumps（腮腺炎）,phlebitis flbats（静脉炎）,ri

7、all in the world.（三）以-ics结尾的学科名称作主语的主谓一致问题 某些以-ics结尾的学科名称作主语时，如physics,mathematics,mechanics,politics statistics,economics,physics is a fundamental subject in science.the third world economics is promising.（四）其它以-s结尾的名词的主谓一致问题 3)表示成双成套的名词，如：chopsticks(筷子),compasses,clothes,glasses,jeans,scissors,sho
