语法就是语言的规律。任何一种语言都有其内在逻辑性(logic)和规律(discipline)。学习一些基本的英语语法,对于快速掌握英语语言的规律,具有事半功倍的作用,尤其是在考试中。下面就是小编为大家梳理归纳的内容,希望能够帮助到大家。
名词
可数名词和不可数名词
表示某一事物,有具体的和抽象的之分。分为可数名词和不可数名词。
强调:不可数名词都默认为单数,所以总是用is或者was;不要根据some、any、a lot of等词去作判断,以免受误导。
1、可数名词如何变“复数形式”:
a.一般情况下,直接加-s,如:book-books, bag-bags, cat-cats, bed-beds;
读音:清辅音后读[s],浊辅音和元音后读[z]。
b.以s. x. sh. ch结尾,加-es,如:bus-buses, box-boxes, brush-brushes, watch-watches;
读音:[iz]。
c.以“辅音字母+y”结尾,变y为i, 再加-es,如:family-families, strawberry-strawberries;
读音:[z]。
d.以“f或fe”结尾,变f或fe为v, 再加-es,如:knife-knives ,thief-thieves
读音:[z]。
e.以“o”结尾的词,分两种情况
1)有生命的+es 读音:[z] 如:mango-mangoes tomato-tomatoes hero-heroes
2) 无生命的+s 读音:[z] 如:photo-photos radio-radios
f. 不规则名词复数: man-men, woman-women, policeman-policemen, policewoman-policewomen, snowman-snowmen, mouse-mice, child-children, foot-feet, tooth-teeth, fish-fish, people-people, Chinese-Chinese, Japanese-Japanese
2、不可数名词没有复数。如果要计算不可数名词所表达的数量,就得在数词和不可数名词之间加上“量词+of”。
例如:a glass of water, a piece of paper, a bottle of juice
冠词
冠词是一种虚词,不能独立使用,通常放在名词的前面,分为“不定冠词”和“定冠词”两种。
1、不定冠词:a、an。
用在单数名词前,表示“一个,一件……”。an用在以元音“音素”开头的单词前。
如:an e-mail, an orange, an old man, an English watch, an hour
2、定冠词:the。用在单数或者复数名词前。the没有具体意思,有时翻译为这、那。
它的基本用法:
(1)用来表示特指某(些)人或某(些)事物。如:The map on the wall is new.
(2)表示说话者双方都知道的人或事物。如:Look at the picture, please.
(3)表示再次提到前面谈过的人或事物。如:This is a stamp. The stamp is beautiful.
(4)用在表示世界上独一无二的事物前。如:the sun太阳 the moon月亮 the earth地球
(5)用在由普通名词构成的专有名词前。如:the Great Wall长城
(6)用在江河、湖海等专有名词前。如:the Changjiang River长江
(7)此外,序数词、形容词级、乐器名称等词前面和一些习惯用语中一般都用定冠词the。
如:the first day, the best boy, play the piano, in the same class
数词
我们学过两类数次:基数词和序数词。
基数词用于表示数量多少,而基数词用于表示次序,常在日期中出现。区别:基数词前面没有“the”;序数词前一定要有“the”。
1、超过二十以上的两位数需要在个位和十位之间加上“-”。如:21 twenty-one
2、三位数以上的则需要在百位数后再加上and。如:101 a/one hundred and one
3、用基数词来修饰可数名词时,一定别忘了它的复数形式。如:十八个男孩 eighteen boys
4、用基数词修饰不可数名词时,如是复数,变它的量词为复数。如:两碗米饭 two bowls of rice
5、序数词一般加“th”,特殊的有:first, second, third, fifth, eighth, ninth, twelfth以及二十及二十以外的整十:twentieth, thirtieth, fortieth…
“第几十几”:前面整十不变,后面“几”改为序数词。如:88 eighty-eighth

相互代词
1)相互代词只有each other和one another两个词组
他们表示句中动词所叙述的动作或感觉在涉及的各个对象之间是相互存在的
例如:
It is easy to see that the people of different cultures have always copied each other.
显而易见,不同文化的人总是相互借鉴的
2) 相互代词的句法功能:
a. 作动词宾语;
People should love one another. 人们应当彼此相爱。
b. 可作介词宾语;
Does bark, cocks crow, frogs croak to each other. 吠、鸡鸣、蛙儿对唱。
说明:传统语法认为,相互关系存在于两个人或物之间用each other, 存在于两个以上人和物之间用one another。现代英语中,两组词交替使用的实例也很多,例如:
He put all the books beside each other.
他把所有书并列摆放起来。
He put all the books beside one another.
他把所有书并列摆放起来。
Usually these small groups were independent of each other.
这些小团体通常是相互独立的。
c. 相互代词可加-'s构成所有格,例如:
The students borrowed each other's notes.
学生们互借笔记。
物主代词
1)物主代词既有表示所属的作用又有指代作用
例如:
John had cut his finger; apparently there was a broken glass on his desk.
约翰割破了手指,显而易见,他桌子上有个破玻璃杯。
物主代词有形容词性(my, your等)和名词性(mine, yours等)两种,形容词性的物主代词属于限定词。
名词性的物主代词在用法上相当于省略了中心名词的 --'s属格结构,例如:
Jack's cap 意为 The cap is Jack's.
His cap 意为 The cap is his.
2) 名词性物主代词的句法功能
a. 作主语,例如:
May I use your pen? Yours works better.
我可以用一用你的钢笔吗? 你的比我的好用。
b. 作宾语,例如:
I love my motherland as much as you love yours.
我爱我的祖国就像你爱你的祖国一样深。
c. 作介词宾语,例如:
Your should interpret what I said in my sense of the word, not in yours.
你应当按我所用的词义去解释我说的话,而不能按你自己的意义去解释。
d. 作主语补语,例如:
The life I have is yours. It's yours. It's yours. 我的生命属于你,属于你,属于你。
反身代词
1) 列表
I-myself
we-ourselves
you-yourself
you-yourselves
she-herself
he-himself
they-themselves
2)做宾语
a. 有些动词需有反身代词
absent, bathe, amuse, blame, dry, cut, enjoy, hurt, introduce, behave
We enjoyed ourselves very much last night.
我们昨晚玩得很开心
Please help yourself to some fish.
请你随便吃点鱼
b. 用于及物动词+宾语+介词
take pride in, be annoyed with, help oneself to sth.
I could not dress (myself) up at that time.
那个时候我不能打扮我自己
注:有些动词后不跟反身代词, get up, sit-down, stand up, wake up等。
Please sit down.
请坐
3) 作表语; 同位语
be oneself: I am not myself today.
我今天不舒服
The thing itself is not important.
事情本身并不重要
4) 在不强调的情况下,but, except, for 等介词后宾语用反身代词或人称代词宾格均可
如:
No one but myself (me) is hurt.
注意:
a. 反身代词本身不能单独作主语。
(错) Myself drove the car.
(对) I myself drove the car. 我自己开车。
b. 但在and, or, nor连接的并列主语中,第二个主语可用反身代词,特别是myself 作主语。
Charles and myself saw it.
