谓语表述主语的行为动作或所处的状态。通常放置在主语之后。谓语的中心词是限定动词,有人称、数的变化。
及物动词不及物动词连系动词情态动词
需要跟有宾语的动词叫及物动词。Children seek independence.The trial raised a number f questins.He has always liked Mr. Philips.He made the shrtest speech I have ever heard.
不需要跟宾语的动词叫不及物动词。Her whle bdy ached.Dnald was lying n the bed.Bb cughed all night.
许多动词往往既是不及物动词又是及物动词。Gus asked me whether I’d like t have dinner with him. I accepted. (vi.)I accepted the invitatin. (vt.)He painted every day. (vi.)He painted vivid prtraits f friends and acquaintances. (vt.)
Father never smked r drank all his life. (vi.)He drank a gd deal f cffee. (vt.)At last she thanked them and left. (vi.)All I knw is that Michael and I never left the huse. (vt.)
谓语大体上可以分为两类:简单谓语和复合谓语。
The plane takes ff at 8 but this mrning it may be delayed by the thick fg.I have tried this way three times and failed three times.
凡是由一个动词或动词短语构成,不管是什么时态、语态、语气,都是简单谓语。
飞机八点起飞,但今天早晨可能会被大雾耽搁。
我用这种方法试了三次,失败了三次。
复合谓语有两类:第一类是由情态动词+动词原型或动词不定式与另外的词构成;第二类是由“系动词+表语”构成。
I wuld like t invite all my friends tthe get-tgether.
我想邀请我所有的朋友去参加聚会。
The weather gets warmer, and the days get lnger.
天气变的暖了,白天变的长了。
意义一致原则、语法一致原则和邻近原则。这三个原则常常发生矛盾,但当发生冲突时,意义一致原则为优先考虑的原则。
英语中的主谓一致主要遵循三个原则:
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,谓语动词也采取单数形式;主语是复数形式,谓语动词也采取复数形式。
1. Mr Black is a well-knwn scientist n AIDS.2. These bks are intended fr children under nine years ld.
布莱克先生是著名艾滋病科学家。
这些书是专门为九岁以下的儿童设计的。
The ld are very well taken care fin ur city.
意义一致原则是指谓语动词的变化是以主语所表达的单、复数概念而定。
(the ld指所有的老年人,指一类人,指复数概念) 老年人在我们城市被照顾得很好。
邻近一致原则是指谓语动词的变化是以靠近谓语动词的主语部分而定。
Nt Jack but his parents are t blamefr the hme accident.
(根据靠近谓语的主语his parents而定)不是杰克而是他父母应为这个家庭事故受到责备。
1 代词each和由every, sme, n, any等构成的复合代词作主语,或主语中含有each, every, 谓语需用单数。
谓语需用单数的几种情形
a Each f us has a tape-recrder.b There is smething wrng with my watch.
The Arabian Night is a bk knwn t lvers f English.
2 当主语是一本书或一条格言时, 谓语动词常用单数。
《一千零一夜》是被英语爱好者所熟知的一本书。
3 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,谓语一般用单数。(用复数也可,意思不变)
