许多PTE考生阅读速度太慢,看文章看不懂,需要回看好几遍,这样做的结果往往就是做题来不及做,越赶越错。其实语法对于PTE阅读速度的提高是至关重要的,这样有更多的时间能够用来分析答案,特别是那些要冲击4个79的同学,扎实的提高语法能力是必经之路。今天小编就说说英语核心语法之主谓一致。
主谓一致是指:
1) 语法形式上要一致,即单复数形式与谓语要一致。
2) 意义上要一致,即主语意义上的单复数要与谓语的单复数形式一致。
3) 就近原则,即谓语动词的单复形式取决于最靠近它的词语,
一般来说,不可数名词用动词单数,可数名词复数用动词复数。例如:
There is much water in the thermos.
但当不可数名词前有表示数量的复数名词时,谓语动词用复数形式。例如:
Ten thousand tons of coal were produced last year.
相关知识点精讲
1.并列结构作主语时谓语用复数,例如:
Readingand writing are very important.读写很重要。
注意:当主语由and连结时,如果它表示一个单一的概念,即指同一人或同一物时,谓语动词用单数,and此时连接的两个词前只有一个冠词。例如:
The ironand steel industry is very important to our life.钢铁工业对我们的生活有重要意义。
典型例题
The Leaguesecretary and monitor ___ asked to make a speech at the meeting.
A. is B. was C. are D. were
答案B.注:先从时态上考虑。这是过去发生的事情应用过去时,先排除A.,C。本题易误选D,因为The League secretary and monitor好象是两个人,但仔细辨别,monitor前没有the,在英语中,当一人兼数职时只在第一个职务前加定冠词。后面的职务用and相连。这样本题主语为一个人,所以应选B。
2.主谓一致中的靠近原则
1)当therebe句型的主语是一系列事物时,谓语应与最邻近的主语保持一致。例如:
There is a pen, a knife and several books on the desk.桌上有一支笔、一把小刀和几本书。
There are twenty boy-students and twenty-threegirl-students in the class.班上有二十个男孩,二十三个女孩。
2)当either…or… 与neither…nor,连接两个主语时,谓语动词与最邻近的主语保持一致。如果句子是由here, there引导,而主语又不止一个时,谓语通常也和最邻近的主语一致。例如:
Either you or she is to go.不是你去,就是她去。
Here is a pen, a few envelops and some paper for you.给你笔、信封和纸。
3.谓语动词与前面的主语一致
当主语有with, together with, like, except, but, no lessthan, as well as等词组成的短语时,谓语动词与前面的主语部分一致。例如:
Theteacher together with some students is visiting the factory.教师和一些学生在参观工厂。
He as wellas I wants to go boating.他和我想去划船。
4.谓语需用单数的情况
1)代词each以及由every,some, no, any等构成的复合代词作主语时,或主语中含有each, every时,谓语需用单数。例如:
Eachof us has a tape-recorder.我们每人都有录音机。
There is something wrong with my watch.我的表坏了。
2)当主语是一本书或一条格言时,谓语动词常用单数。例如:
TheArabian Night is a book known to lovers of English.《天方夜谭》是英语爱好者熟悉的一本书。
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。例如:
Three weeks was allowed for making the necessary preparations.用三个星期来做准备。
Tenyuan is enough.十元够了。
5.指代意义决定谓语的单复数
1)代词what, which, who, none, some,any, more, most, all等词的单复数由其指代的词的单复数决定。例如:
All is right. 一切顺利。
All are present. 人都到齐了。
2)集体名词作主语时,谓语的数要根据主语的意思来决定。如family, audience, crew,crowd, class, company, committee等词后,谓语动词用复数形式时强调这个集体中的各个成员,用单数时强调该集体的整体。例如:
His family isn't very large.他家成员不多。
His family are music lovers. 他家个个都是音乐爱好者。
但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。例如:
Are there any police around?附近有警察吗?
3)有些名词,如variety, number, population, proportion, majority等有时看作单数,有时看作复数。例如:
Anumber of +名词复数+复数动词。
Thenumber of +名词复数+单数动词。
Anumber of books have lent out.
Themajority of the students like English.
6.与后接名词或代词保持一致的情况
1)用halfof, most of, none of, heaps of, lots of, plenty of等引起主语时,谓语动词通常与of后面的名词/代词保持一致。例如:
Mostof his money is spent on books.他大部分的钱化在书上了。
Most of the students are taking an active part insports.大部分学生积极参与体育运动。
2)用a portion of, a seriesof, a pile of, a panel of等引起主语时,谓语动词通常用单数。例如:A series of accidents has been reported.媒体报道了一连串的事故。
A pile of lots was set beside the hearth.炉边有一堆木柴。
3)如many a或more than one所修饰的短语作主语时,谓语动词多用单数形式。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。例如:
Manya person has read the novel. 许多人读过这本书。
Morethan 60 percent of the students are from the city.百分之六十多的学生来自这个城市。
