英语中,状语,标语,系动词,情态动词等等,谁能帮我解决一下
如题
(一)、副词及其基本用法
副词主要用来修饰动词,形容词,副词或其他结构.
一、副词的位置:
1) 在动词之前.
2) 在be动词、助动词之后.
3) 多个助动词时,副词一般放在第一个助动词后.
注意:
a. 大多数方式副词位于句尾,但宾语过长,副词可以提前,以使句子平衡.
We could see very clearly a strange light ahead of us.
b. 方式副词well,badly糟、坏,hard等只放在句尾.
He speaks English well.
二、副词的排列顺序:
1) 时间,地点副词,小单位的在前,大单位在后.
2) 方式副词,短的在前,长的在后,并用and或but等连词连接.
Please write slowly and carefully.
3) 多个不同副词排列:程度+地点+方式+时间副词
注意:副词very 可以修饰形容词,但不能修饰动词.
改错:(错) I very like English.
(对) I like English very much.
注意:副词enough要放在形容词的后面,形容词enough放在名词前后都可.
I don't know him well enough.
There is enough food for everyone to eat.
There is food enough for everyone to eat.
(二)及物动词与不及物动词
英语中按动词后可否直接跟宾语,可把动词分成及物动词与和及物动词.
1.及物动词: 字典里词后标有vt. 的就是及物动词.及物动词后必须跟有动作的对象(即宾语),可直接跟宾语.see 看见 (vt.) +宾语 I can see a boy.
2.不及物动词:字典里词后标有vi. 的就是不及物动词.不及物动词后不能直接跟有动作的对象(即宾语).若要跟宾语,必须先在其后添加上某个介词,如to,of ,at后方可跟上宾语.
具体每个动词后究竟加什么介词就得背动词短语了,如listen to,look at…..
3. 宾语(动作的对象):是名词或代词,或相当于名词的词或短语(如动名词).其它词不看作动作的对象呢.
4.举例:“看”
(1)see 看见 (vt.) +宾语 I can see a boy.
(2)look 看 (vi.) x宾语(即不能直接加宾语). Look! She is singing.
Look carefully! (注意:carefully 是副词,不是名词,故不作宾语哟)
(3)look at 看…….+宾语 Look at me carefully! (me是代词,作宾语了)
(三)终止性动词
英语中,动词按其动作发生的方式、动作发生过程的长短,可分为延续性动词和终止性动词.
终止性动词也称非延续性动词、瞬间动词或短暂性动词,表示不能延续的动作,这种动作发生后立即结束.如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等.
终止性动词的用法特征
1.终止性动词可用来表示某一动作完成,因此可用于现在完成时.如:
The train has arrived.火车到了.
Have you joined the computer group?你加入电脑小组了吗?
2.终止性动词表示的动作极其短暂,不能持续.因此,不可与表示一段时间的状语连用(只限肯定式).如:
(1)他死了三年了.
误:He has died for three years.
正:He has been dead for three years.
正:He died three years ago.
正:It is three years since he died.
正:Three years has passed since he died.
(2)他来这儿五天了.
误:He has come here for five days.
正:He has been here for five days.
正:He came here five days ago.
正:It is five days since he came here.
正:Five days has passed since he came here.
(1)、(2)句中的die、come为终止性动词,不能与表示"段时间"的状语连用.那么,应如何正确表达呢?可以采用下面的四种方法:
(1)将句中终止性动词转换为相应的延续性动词,如上面两例中的第一种正确表达方式.下面列举几例:leave→be away, borrow→keep, buy→have, begin/start→be on, die→be dead, move to→live in, finish→be over, join→be in/be a member of, open sth.→keep sth. open, fall ill→be ill, get up→be up, catch a cold→have a cold.
(2)将句中表示"段时间"的状语改为表示过去确定时间的状语,如下面两例中的第二种正确表达方式.
(3)用句型"It is+段时间+since..."表达原意,如上面两例中的第三种正确表达方式.
(4)用句型"时间+has passed+since..."表达原意,如上面两例中的第四种正确表达方式.
3.终止性动词可用于现在完成时否定式中,成为可以延续的状态,因而可与表示一段时间的状语连用.如:
He hasn't left here since 1986.
I haven't heard from my father for two weeks.
4.终止性动词的否定式与until/till连用,构成"not+终止性动词+until/till ..."的句型,意为"直到……才……".如:
You can't leave here until I arrive.直到我到了,你才能离开这里.
I will not go to bed until I finish drawing the picture tonight.今天晚上直到我画完画,我才上床睡觉.
5.终止性动词可以用于when引导的时间状语从句中,但不可以用于while引导的时间状语从句中.when表示的时间是"点时间"(从句谓语动词用终止性动词),也可以是"段时间"(从句谓语动词用延续性动词).而while表示的是一个较长的时间或过程,从句谓语动词用延续性动词.如:
When we reached London, it was twelve o'clock. (reach为终止性动词)
Please look after my daughter while/when we are away. (be away为延续性动词短语)
6.终止性动词完成时不可与how long连用(只限于肯定式).如:
误:How long have you come here?
正:How long have you been here?
正:When did you come here?
(四)复数名词
英语上名词按可数与否可分为可数名词和不可数名词.
可数名词按数目又可分为单数名词和复数名词两类.(注:不可数名词没有复数形式如water(水).)
单数名词主要用来表示“一个”东西的概念.两个及其以上就应用复数名词来描述.
怎样把单数名词变复数名词呢?方法如下:
1.一般在名词词尾加-s.如:dog-dogs, house-houses, gram-grams.
2.以-o或-s,-sh, -ch及-x结尾的名词加-es构成其复数形式.如: tomato-tomatoes, kiss-kisses, watch-watches, box-boxes, bush-bushes.
3.有些以-o结尾,是外来语或缩写名词, 则加-s.如:piano-pianos, dynamo-dynamos, photo-photos, kimono-kimonos.
4.有些以-o结尾的名词,其-o前是元音字母则加-s.如:studio-studios, radio-radios.
以-oo结尾的名词只加-s.如:zoo-zoos.
5.以-y结尾的名词,且-y前是一个辅音字母,则把-y去掉,加-ies.如:baby-babies, university-universities, fly-flies, impurity-impurities.
如果以-y结尾的名词,-y前是一个元音字母,则直接加-s.如:boy-boys, donkey-donkeys.
6.以-f或-fe结尾的名词,一般将-f,-fe去掉,加-ves.如:wife-wives, wolf-wolves, calf-calves.
这类名词还有:life, knife, self, shelf, leaf, thief, sheaf, half等.
名词scarf, wharf, hoof, handkerchief的复数形式或加-s或去掉-f加-ves,即scarfs或scarves, wharfs或wharves, hoofs或hooves, handkerchiefs或handkerchieves.
也有些以-f或-fe结尾的名词只加-s.如:cliff-cliffs, belief-beliefs, safe-safes, roof-roofs, chief-chiefs等.
7.有些名词以改变元音构成其复数形式.如:man-men, woman-women, goose-geese, foot-feet, mouse-mice, louse-lice, tooth-teeth等. child的复数为children, ox的复数为oxen.
8.有些表示生物的名词,其复数形式与单数相同.如:fish-fish, sheep-sheep, deer-deer.这类名词还有aircraft, means等
(五)冠词的用法
1. 不定冠词的用法
冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义.英语中的冠词有三种,一种是定冠词(the Definite Article),另一种是不定冠词(the Indefinite Article),还有一种是零冠词(Zero Article).
不定冠词a (an)与数词one 同源,是"一个"的意思.a用于辅音音素前,一般读作[e],而an则用于元音音素前,一般读做[en].
1) 表示"一个",意为one;指某人或某物,意为a certain.
A Mr. Ling is waiting for you.

A knife is a tool for cutting with.
Mr. Smith is an engineer.
3) 词组或成语.

Take the medicine. 把药吃了.
2)上文提到过的人或事:
He bought a house. I've been to the house.

3)指世上独一物二的事物:
the sun, the sky, the moon, the earth
4)单数名词连用表示一类事物,如:the dollar 美元;

Where do you live? I live on the second floor. 你住在哪?我住在二层.
That's the very thing I've been looking for. 那正是我要找的东西.
6)与复数名词连用,指整个群体:
They are the teachers of this school.指全体教师)
They are teachers of this school. (指部分教师)
7)表示所有,相当于物主代词,用在表示身体部位的名词前:
She caught me by the arm.. 她抓住了我的手臂.
8)用在某些由普通名词构成的国家名称、机关团体、阶级、等专有名词前:
the People's Republic of China 中华人民共和国
the United States 美国

10) 用在姓氏的复数名词之前,表示一家人:
the Greens 格林一家人 (或格林夫妇)
11) 用在惯用语中:
in the day, in the morning (afternoon,evening), the day after tomorrow
the day before yesterday, the next morning,
in the sky (water,field,country)
in the dark, in the rain, in the distance,

3)抽象名词表示一般概念时,通常不加冠词;

4)物质名词表示一般概念时,通常不加冠词,当表示特定的意思时,需要加定冠词;

不定冠词常位于名词或名词修饰语前.注意:
a. 位于下列形容词之后: such,what,many,half,
I have never seen such an animal.
Many a man is fit for the job.
b. 当名词前的形容词被副词as, so, too, how, however, enough修饰时,不定冠词应放在形容词之后:

c. quite,rather与单数名词连用,冠词放在其后.
但当rather,quite 前仍有形容词,不定冠词放其前后均可.如:quite a lot

当名词被比较级形容词修饰时,不定冠词通常置于比较级形容词之后.
2) 定冠词位置
