主谓一致(2)一、语法一致原则1．概述语法一致是指主语和谓语动词之间的一致关系主要表现在“数”的形式上，即用作主语的名词词组中心词和谓语动词在单复数形式上的一致。
2．用法(1)不可数名词或可数名词单数形式作主语时，谓语动词用单数形式；可数名词的复数形式作主语时，谓语动词用复数形式。These tys are designed fr children under three years ld．这些玩具是为三岁以下儿童设计的。There is a red glass n the desk．桌子上有一只红色玻璃杯。Water is a liquid withut clur，smell r taste．水是一种无颜色、无气味或无味道的液体。
(2)当主语本身是不定代词either，neither，each，ne，the ther，anther，anybdy，anyne，anything，smebdy，smene，smething，everybdy，everyne，everything，nbdy，n ne，nthing 等时，谓语动词用单数形式。Nthing is impssible t a willing heart．世上无难事，只怕有心人。Each f the students has a bk．每个学生都有一本书。
(3)单个的动词不定式、动词-ing形式(短语)或主语从句作主语时，谓语动词一般用单数形式。Swimming in rivers in summer is a gd sprt，but t swim in rivers in winter needs great willpwer．夏天在河里游泳是一项很好的运动，但冬天在河里游泳需要极大的意志力。
[温馨提示]what引导的主语从句作主语时，谓语动词的单复数取决于作表语的名词的单复数。What we need is mre mney，but what they need are bks．我们需要的是更多的钱，但他们需要的是书。
(4)主语是由“many a＋名词”或“mre than ne＋名词”构成，其意义虽为复数，但是谓语动词仍然用单数形式。Mre than ne persn was injured in the accident．不止一人在这次事故中受伤。Many a persn has been cheated by such tricks．许多人都已被这类骗局所欺骗。
(5)“quantities f＋复数名词/不可数名词”作主语时，谓语动词用复数形式；“a quantity f＋复数名词/不可数名词”作主语时，谓语动词用单数形式。Large quantities f time were spent n rehearsal．大量的时间花在排练上。A quantity f nuts is n the desk．桌子上有大量的坚果。
(6)当主语是“mst/sme/half/the rest/分数/百分数＋f＋名词” 时，如果f后面的名词表示单数概念或为不可数名词，则谓语动词用单数形式；如果f后面的名词表示复数概念，则谓语动词用复数形式。Tw thirds f the students supprt the plan．三分之二的学生支持这项计划。 Three furths f the surface f the earth is sea．地球表面的四分之三是海洋。Eighty per cent f the emplyees in the cmpany are frm Beijing．公司80%的员工来自北京。
(7)a great deal f，a large amunt f修饰不可数名词时，谓语动词通常用单数形式；large amunts f修饰不可数名词时，谓语动词通常用复数形式。A large amunt f grain has been eaten by birds．大量的谷物被鸟吃了。Large amunts f grain have been eaten by birds．大量的谷物被鸟吃了。
(8)“a number f＋名词复数”作主语时，谓语动词用复数形式，意为“大量，许多”；“the number f＋名词复数”作主语时，谓语动词用单数形式，意为“……的数量”。 Nwadays，a large number f wmen，especially thse frm the cuntryside，wrk in the clthing industry．当前，很多妇女，特别是那些来自乡村的妇女，都在服装厂工作。 The number f freign students attending Chinese universities has been rising steadily since 1990．在中国上大学的外国留学生的数量自从1990年以来在稳步增长。
二、就近一致原则1．概述谓语动词的单复数形式取决于最靠近它的词语(主要指名词)的单复数形式，这种一致关系所依据的原则叫作就近一致原则。
2．用法(1)由r，either ...，neither ...，whether ...，nt nly als ...，nt ...等连接的并列名词作主语时，谓语动词常与最邻近的主语在单复数上保持一致。Nt nly the students but als the teacher wants t g climbing．不仅学生们想去爬山，老师也想。Either Mary r yu are t blame fr the fault．要么玛丽，要么你应为这个过失负责。
[温馨提示]“with/alng with/tgether with/as well as/except＋名词”置于主语后充当插入语时，谓语动词一般仍与前面的名词在单复数上保持一致。Prnunciatin，as well as grammar and vcabulary，changes very quickly frm ne area t anther．与语法和词汇一样，发音因地区差异而变化很快。
(2)在there be句型中，be动词要和离它最近的主语保持一致。There is a pen，tw bks and many pencils n the desk．桌子上有一支钢笔、两本书和许多铅笔。There are tw bks，a pen and many pencils n the desk．桌子上有两本书、一支钢笔和许多铅笔。
