初中英语知识点总结1知识点总结
在英语中,句子中的谓语动词在人称和单、复数形式上必须和主语保持一致,这就是我们通常说的“主谓一致”。这一点看似简单,但在实际运用中却常常遇到麻烦。一般情况下,主谓之间的一致关系由以下三个原则的支配: 语法一致原则、 意义一致原则和就近原则。
一、语法一致
主谓一致的原则是指主语和谓语从语法形式上取得一致:主语是单数形式,谓语也采取单数形式;主语是复数形式,谓语亦采取复数形式.例如:
He often helps me learn English. (主语是单数形式,谓语也采取单数形式) .
My friends often help me learn English. (主语是复数形式,谓语也采取复数形式)
但主语和谓语从语法形式上取得一致的问题远不只上述的那么简单,有许多方面的情况需要去具体地对待:
1、不定式,动名词,以及从句作主语时应看作单数,谓语动词用单数.
例如: Reading aloud is helpful to learn English.大声朗读对学习英语是有帮助的。
What he said has been recorded .他说的话已被录音了.
2、不定代词one, every, each, everybody, everyone, one of, no one, nothing, nobody, someone, somebody, either, neither, many a 等作主语或是修饰主语时应看作单数,谓语动词用单数.但none 作主语时,谓语动词既可用单数也可用复数,这要取决于说话人的看法。
例如:Neither of my sisters likes sports .我的妹妹中没人喜欢运动.
Every boy and girl shows great interest in this book .每个男孩和女孩对这本书都表现出很大的兴趣.
3、表示国家,机构,事件,作品等名称的专有名词作主语时应看作单数,谓语动词用单数.
例如: One Thousand And One Nights tells people lots of interesting stories . 《一千零一夜》给人们讲了许多有趣的故事。
4、 a kind of, the number of等与名词构成名词短语作主语时应看作单数,谓语动词用单数.
例如: The number of workers in the factory is 400. 这个工厂里工人的数量是400.
A kind of rose in the garden smells very pleasant.这座花园里有一种玫瑰香气怡人.
5、由some, several, both, few, many, a number of 等词修饰主语,或是由它们自身作主语时应看作复数,谓语动词用复数.另外,由and连接两个主语时,谓语一般用复数.
例如: On the seashore, some people are playing volleyball 海边,有些人在打排球。
Both of us are fond of watching football games .我们俩都喜欢看足球赛.
A number of will-be graduates are voluntarily going to work in the West of China. 许多即将毕业的学生打算自愿去中国西部工作.
6、有些表示数量的百分数,分数等后面加名词或代词作主语时,要根据这个名词或代词来决定其谓语动词的单复数形式.如:a lot of, most of, any of, half of , three fifths of, eighty percent of, some of, none of, the rest of , all of等后接不可数名词,或是单数形式的名词作主语时应看作单数,谓语动词用单数;但如果后接可数名词的复数形式作主语时应看作复数,谓语动词用复数.
例如: A lot of money in the shop was stolen yesterday. 昨天那家商店丢失了许多钱.
A lot of students are from England in the school.那个学校里很多学生来自英国。
二、意义一致
这一原则是指,从意义着眼来解决主谓一致问题.有时主语形式上为单数,但意义上却是复数,那么谓语依意义也用复数形式;而有时主语形式上为复数,但意义上却是单数,那么谓语依意义亦用单数形式.
1) 当主语后面接由but, except, besides ,as well as, as much as, including,more than,no less than, rather than, together with等引导的词组时,其谓语动词的单复数形式通常由前面的词来决定。在这样的句子里,这些词所引导的词组不影响主语自身的单,复数形式,它们在句子里其实是状语.
例如: The teacher, with all his students, is going to have a picnic this weekend.老师打算这个周末与学生们一起去野炊.
The students, together with their teacher , are going to have a picnic this weekend.学生们打算这个周末与他们的老师一起去野炊.
我们完全可以将上面句子中的那些词组都分别搬到句首或是放到句末去,因为它们在句子里是状语: The students are going to have a picnic this weekend together with their teacher.
2) 表示时间,金钱,距离,体积,重量,面积,数字等词语作主语时,,谓语动词常用单数形式。如:
Eight hours of sleep is enough. ……此处隐藏14292个字…… B isn't he C do I D don't I
解析:本题考查反意疑问句的构成。当陈述部分是I think 加从句时,疑问句应和从句的人称时态保持一致。所以排除C和D;主句部分don't表明是否定句,所以后面应用肯定形式。
答案:A
误区提醒
对于反意疑问句的回答,一定要根据事实来回答,尤其是“前否定,后肯定”的反意疑问句的回答,更是我们容易出错的地方,一定要注意哦!
典型例题:——You've never seen dinosaur eggs, have you?
——_________. How I wish to visit the Dinosaur World.
A Yes, I have B No, I haven't C No, I have D Yes, I haven't
解析:本题考查反意疑问句的回答。根据答语“我多么希望去参观恐龙世界”可知他没去过恐龙世界,没见过恐龙蛋,根据“Yes+肯定事实”和“No+否定事实”的原则,可以得出答案。
答案:B

初中英语知识点总结15在复合句中,修饰某一名词或代词的从句叫做定语从句,它的作用相当于形容词,被修饰的词叫做先行词。
1、定语从句的位置。
1)定语从句一般地说要放在先行词之后,无论这个词在句中充当何种成分。
The student who answered the question is bill.
2)有时先行词后还有一个作定语的词或词组时,定语从句则应放在上述成分之后。
Do you know anyone in our class whose father is a business man?
2、定语从句的引导词
1)定语从句的引导词是由关系代词或关系副词充当的。
关系代词有who/whom/whose/that,关系副词有when/where/why,它们除了引导从句的作用外,还要在从句中充当一定的成分。关系代词和关系副词的选用要看其在从句中发挥的作用,与主语没有任何关系。
在从句中充当主语的有who/which/that.
在从句中充当宾语的有whom/which/that.
在从句中充当定语的有whose.
在从句中充当状语的有when/where/why.
当定语从句所修饰的先行词是人时,关系代词要用who(主格),whom(宾格),也可以用that,以及whose(所有格),先行词是物时,关系代词要用which,也可用that.whom/which/that在从句中作宾语时往往可以省略。
例如:
The students who do not study hard will not pass the examination.
Do you know the man(whom)mr green shook hand with?
The letter(which)I received yesterday is from my sister.
Who is the man(that)is reading a magazine over there?
The book(that) you lent me is very ingteresting .
I will never forget the day when I joined the party.
Last year I went to the village where I was born.
This is the reason why she will go to london.
2)在先行词相同的情况下,根据它们在定语从句中所起的语法作用,可用不同的引导词连接不同的定语从句。
例如:
This is the school where I students for six years.(school或student的状语)。
This is the school which he mentioned just now.(school作menttioned的宾语).
