1、第30课 主谓一致课堂突破概念在英语中，句子的主语和谓语动词要保持数上的一致关系，叫主谓一致。使用原则语法一致原则句子的主语是单数形式，谓语动词要用单数形式；主语是复数形式，谓语动词用复数形式。如：Australia is an extremely rich country. 澳大利亚是个非常富裕的国家。All the students except Lin Tao are planting trees on the hills. 除了林涛以外所有的学生都在小山上植树。意义一致原则谓语动词该用单数还是复数取决于主语所表达的内容在含义上是单数意义还是复数意义。如：The Chinese are
2、industrious. 中国人是勤劳的。邻近原则谓语动词该用单数还是复数形式，取决于最邻近它的名词、代词或其他词的数。另外，neither.nor,either.or, not only.but also.连接两个名词或代词作主语时，或由there, here引导的句子，并且主语不止一个时，谓语动词通常与邻近它的那个主语保持数上的一致。如：There is a dictionary and some books on the desk. 桌子上有一本词典和一些书。特殊的情况1. 表示时间、重量、数目、价格、长度、数学运算等的词或词组作主语时，尽管它们是复数形式，但如果把这些复数形式的词或词组

4、nd teacher is one of my friends. 那位诗人兼教师是我的一位朋友。（诗人和教师指的是同一个人）4. 集合（体）名词people, police一般看作复数意义，谓语动词要用复数形式。另外一些集合（体）名词，如family, enemy, class, army等作主语时，谓语动词用单数形式还是复数形式，要根据这些词在句中的实际含义而定。当它们表示的是整体意义时，谓语动词用单数形式；当它们强调或着重指个体成员时，谓语动词用复数形式。如：Are there any police around? 附近有警察吗？ My family is big. 我家很大。 My fa
5、mily are all at home. 我家人都在家。5. 名词性物主代词mine, yours, his, hers, its, ours, theirs等作主语时，谓语动词的数取决于该动词后面名词的数，动词后面的名词是单数形式，谓语动词用单数形式；动词后面的名词为复数形式，谓语动词用复数形式。如：His is a new bike. 他的是新自行车。Ours are old bikes. 我们的是旧自行车。6. many a意为“许多”，但因其后面跟的是单数名词，谓语动词用单数形式。如：Many a person has had that kind of experience. 许多人

7、口是农民。9. .percent of+不可数名词作主语，谓语动词用单数形式；.percent of+可数名词复数作主语，谓语动词用复数形式。如：50 percent of the water is not very fresh. 50%的水是不新鲜的。50 percent of the students come from Shanghai. 50%的学生来自上海。10. every+单数名词+and+every+单数名词作主语时，谓语动词用单数。Every boy and every girl wants to go there. 每个男孩、女孩都想去那儿。当堂检测一、用所给动词的适当形式
