主谓一致语法.doc

主谓一致主谓一致，即句子的主语和谓语在数上要保持一致。它是中学英语重点语法内容之一，也是高考必考的语法点之一。下面我们从三方面来看看高考中有关主谓一致的一些高频考点。A单一主语的情况1、谓语用单数当主语是不可数名词、可数名词单数、单数代词、不定式(短语)、动名词(短语)或从句等时，谓语动词用单数，如：The work is important.To serve the country is our duty.代词each以及由every、some、no、any等构成的复合代词作主语，或主语中含有each、 every时，谓语动词用单数，如：Each of the students, working hard at his or her lessons, hopes to go to university.表示金钱、时间、价格或度量衡的复合名词作主语时，通常把这些名词看作一个整体，谓语动词一般用单数，如：Three weeks was allowed for making the necessary preparations.当主语是一本书、一条格言或一个学科时，谓语动词常用单数，如：Mathematics is my favorite.2、“the + 形容词/分词”作主语时：指“一类”人或事物时，谓语动词常用复数，如：The poor need help from the society.指“某一个”人或“抽象的”事物时，谓语动词用单数，如：The agreeable is not always the useful.B并列结构作主语的情况1当主语是由and并列的两个或两个以上的部分组成时，谓语动词一般都用复数，如：Reading and writing are very important. 如果当主语虽然是由and并列的两部分组成，但表示的是一个单一的概念时，即指同一人或同一物时(and此时连接的两个词前只有一个冠词)，谓语动词用单数，如：The iron and steel industry is very important.2、当主语由“either.or.”或“neither.nor.”连接时，谓语动词与最邻近的主语保持一致，如：Either you or she is to go.3、当主语是由“not A, but B”或“not only A, but also B”结构组成时，谓语动词的数取决于B的数，如：Not you but your brother is to blame.4、当主语后面接有由with、together with、like、except、including、but、no less than、as well as等词引起的短语时，谓语动词的数与这些词前面的主语的数保持一致，如：All but Jane know the secret.其他情况1、“One of + 复数名词 + 定语从句”中，从句的谓语动词一般用复数，如：This is one of the best novels that have appeared this year.但如果“one”前有“this、the、the only”等词修饰时，定语从句的引导词指代one，作从句主语时，从句谓语动词用单数，如：He was the only one of the boys who was praised.2、在there be句型中，当真正的主语是一系列事物时，谓语应与最邻近的那部分保持一致，如：There is a pen, a knife and several books on the desk.There are twenty boy-students and twenty-three girl-students in the class.3、如果句子是由here、there引导，而主语不只由一个词构成，且表示复数概念时，谓语动词的数通常和最邻近的主语一致，如：Here are two books for you.4、当主语被half of、part of、most of、a portion of等修饰时，谓语动词通常与of后面的名词、代词保持一致，如：Most of the students are taking an active part in sports.5、在这样一些短语，如“many a”或“more than one”所修饰的词作主语时，谓语动词多用单数形式，如：Many a person has read the novel.但由“more than.of”作主语时，动词应与其后的名词或代词保持一致，如：More than 60 percent of the students are from the city.6、主语是“a number of (许多)/ a variety of (各式各样) + 复数名词”时，谓语动词常用复数，如：A number of students in this class are (is) from Sichuan.There are a variety of toys in this shop.注意：“the number(数目)/ the variety(种类) + of + 复数名词”作主语时，谓语动词用单数，如：The number of students in this college has doubled.The variety of goods in this shop is rich.【真题演练】1.
