主谓一致:主要看句子开头的人或物是不是一个(除I或YOU)。一个人或物注意用动词单数形式,如is,was,does,works等等。
时态吗:主要看标志。now,look,listen等标志正在进行(be +ving)。yesterday,last night,last year 等过去的时间用一般过去时(动词过去式)。
名词单复数:前有a,an用单数啊,大于一的数量用复数啊。不可数名词用原形啊。
句子是按照一定的语法规律组成的,表达一个完整的意义。一个句子一般由两部分构成,即主语部分和谓语部分,这两部分也叫做句子的主要成分。句子的次要成分包括宾语,定语,状语,表语等。句子成分是句子中起一定功用的组成部分。
1)主语:是一句的主体,是全句述说的对象,常用名词,数词或代词担任,一般放于句首。如:
Students study. (学生学习。)
We are friends.(我们是朋友)
这两句话中单词students是个名词,we是代词,它们在句中做主语。
2)谓语:是对主语加以陈述,表示主语的行为或状态,常用动词或者动词词组担任,放在主语的后面。如:
Students study. (学生学习。)
We are friends. (我们是朋友)
这两句话中单词study和are都是动词,study叫做实意动词,are叫做be动词,它们在句中作谓语。
3)宾语:表示行为的对象,常由名词或者代词担任。放在及物动词或者介词之后。如:
They are teachers. ( 他们是老师。)
I play with him. (我和他一起玩。)
这两句话中单词teachers是名词,单词him是带词,它们在句中作宾语。
4)定语:是用来说明或者*名词的成分,常用形容词或者相当于形容词的短语或从句担任。形容词放在名词之前,相当于形容词的短语或从句放在名词的后面。如:
This is a red sun.(这是个红太阳.)
He is a tall boy.(他是个高个子男孩。)
这两句话中单词red和 tall都是形容词,它们作定语。
5)状语是用来说明动词,形容词,副词或整个句子的成分。常由副词担任。修饰动词时可以放在动词之前,也可以放在动词之后;修饰形容词或副词时放在它们之前。如:
The students study hard. (这些学生学习努力。)
I often write to him. (我常给他写信。)
The bag is too heavy. (这个书包太重了。)
这三句话中单词hard 和often修饰的都是动词,第三句话中单词too修饰的是形容词,它们都作状语。
6)表语:用来说明主语的性质或状态。一般由名词或者形容词担任。如:This table is long. (这个桌子是长的。)
通常情况下,主语和宾语前的成分是定语,谓语前的成分是状语,时间词作状语放在句子后面。句子的成分分布如下:
(定语) 主语 (状语) 谓语 (定语) 宾语 (状语)
如:(The tall) boy (often) go (to the big) zoo.
(The happy) child --- went (his) home yesterday.
请分析下面句子的结构说出各个成分
1)I have two elder sisters. (我有两个姐姐。)
2) They don't swim very well.(他们游泳不太好。)
3) Do you go to school every day? (你每天去上学吗?)
4) I really want a cup of tea.(我真的想要一杯茶。)
5) Miss Smith teaches English very well.(史密斯先生教英语非常好。)
语法其实并没有一些人想象的那么可怕,其实里面有很多趣味。
第一讲 英语句子成分
WARM-UP:1)The teacher in the classroom. 2)Sang many songs and danced happily. 3)She attracts. 4)Many people living in the country. 5)All the books on the desk over there.
以上这些形式都不能构成英语句子。
英语句子(sentence)=主语+谓语(核心:主动词)
英语句子成分歌
英语句子八呀八大块, 主谓宾表真呀真实在;
补语跟着宾语表语跑, 定语同位(语)专把名词踹。
状语的位置它自由自在, 忽右忽左随心所欲摆。
浑身的毛病真呀真不少, 前后乱窜它还会加塞。(RAP)
I.八大成分的概念和构成
1.主语(名词代词形):句子的主体,是谓语陈述,说明的对象。

自古音乐分两种,好的和坏的。
构成形式:1)限定词2)形容词3)名词4)数词5)不定式6)-ing形式7)过去分词8)介词短语9)副词10)关系从句
8. 同位语:对被修饰对象进行补充说明或进一步解释。

II.成分关系
1.补语跟着宾语表语跑:
补语跟在宾语和表语的后面构成宾补和表补。把有宾补的句子变成被动语态,则宾补就变成了主补。
To love others makes us happy…to love ourselves makes us lonely.(宾补)
We are made happy to love others…we are made lonely to love ourselves.(主补)
爱他人使我们幸福,在自己使我们孤单。
2.定语,同位(语)专把名词踹:
定语,同位语修饰名词性形式
Experience is the best teacher.(被定语所修饰的形式为名词)
They are going to Melbourne, the beautiful city in southern Australia.(同位语所修饰的形式为名词)
3.谓语动词由状语修饰
When you reach for the stars, you may not quite get one, but you won’t come up with a handful of sand either.
你想摘下天上的星星,可能一个也摘不下;但也不会一无所获。
1、主语:
(1)由名词、代词(人称代词用主格)、动词不定式、动名词等充当,说明动作是“谁”发出的。如:The painter painted a very nice picture. (画家画了一幅漂亮的画。) / They fought against SARS bravely. (他们勇敢地与非典搏斗。) / To see is to believe. (耳听为虚眼见为实). / Helping animals is to help people. (帮助动物就是帮助人类。)

(3) 宾语一般放在及物动词或介词的后面,但是在疑问句中,如果宾语是疑问词,则宾语要放在句首。介词的宾语如果是疑问词,则可以放在介词后或句首。如:What did he see? (他看见了什么?) / What does he write a letter with? (他用什么写的信?) / With what does he write a letter? (他用什么写的信?)
(4)“动词+副词+宾语”结构中,如果宾语是代词,则代词必须放在“动”“副”之间。如:Please put the shoes away. (请把鞋子收起来。) / Please put away the shoes. (请把鞋子收起来。) / Please put them away. (请把它们收起来。)
(5) 动词后面跟双宾语时可以采用两种结构:
①动词+间接宾语(人)+直接宾语(物)。如:He often gives me some help. (他常常帮我。)
②动词+直接宾语+介词+间接宾语。注意,一般情况介词用to,但动词是make, buy, borrow时,介词用for.如: Please make me a kite. (请给我做个风筝。)或Please make a kite for me.
(6) 在“动词+宾语+宾补”结构中,如果宾语是不定式、动名词、宾语从句,则常用it做形式宾语,而将实际的宾语移到补语后面去。如:I found the job rather difficult. (我发觉这个工作相当难做。) / I found it rather difficult to do the job.
(7) 宾语可以由从句充当,详见“宾语从句”。
4、表语:

(2) 表语只能放在连系动词(如:be,look,become,turn get,grow,feel,seem) 之后,对表语进行提问的句子除外。
(3) 代词做表语一般用主格,口语中常用宾。如:It’s I. (It’s me.)是我。
(4) 只能作表语的形容词有:sorry,afraid,alone,asleep,awake,ill,well,sure,interested等等。He was terribly sorry for his carelessness.(他很为他的粗心而歉疚。) / Please make no noise here; the baby is asleep.(请不要发出响动,婴儿正熟睡呢。) / I am only interested in sitting in a boat and doing nothing at all!(我只是对独坐孤舟无所事事感兴趣。) / I am not alone in thinking so.(并非只有我才这样想的。)
(5) 表语也可以由从句充当,详见“表语从句”。
5、定语:
(1) 修饰名词或代词的成分,常由形容词、名词(含所有格)、代词(物主、指示、疑问、不定)、介词短语、不定式(短语)充当,在初三阶段还学习了定语从句做定语的知识。如:Put it in the top drawer.(把它放在最上层的抽屉里。) / France and Switzerland are European countries. (法国和瑞士是欧洲国家。) / His mother and father are both college teachers.(他的父母都是大学教师。) / This is the day that I can never forget in my life.(这是我一辈子难忘的日子。)
(2) 单词做定语时一般放在被修饰的名词前面,而且有一定的次序:
冠词/
物代
年龄/形状/
大小/温度
色彩
来源
质地/
材料
目的/
用途
被修饰的名词(中心词)

…
Chinese,
English,
American,
…
wooden,
woolen,

swimming,
…
box,
shoes,
room,

…
long,short,
round, square…
big, large,
small, little…
hot, cold,
warm, cool…
(3) 时间副词(now,then,today,yesterday,...)、地点副词(here,there,back,in,out,home,...作定语时放在被修饰的名词后面。如:I could not find my way out, so I stayed there all along. (我找不到出去的路,所以就一直呆在那儿。)
(4) 介词短语修饰名词时只能放在名词的后面:The monkey in the cage was caught yesterday. (笼子里的猴子是昨天逮着的。)
(5) 形容词修饰复合不定代词时,往往后置。如:He remembered everything unusual. (他记得所有不寻常的事情。)
(6) 定语还可以用从句充当,详见 定语从句。
(7) 注意:由于定语属于修饰性的成分,因此它常归入主语、宾语、表语之中,不作为句子的主要成分。
6、状语:
(1) 说明动作“何时”、“何地”、“如何”发生,或者说明形容词或副词的程度,一般由副词、介词短语、不定式、状语从句等充当。如:I was not born yesterday.(我又不是昨天才出世的娃娃。)/ For many of these families a college ecation was something new.(对其中的许多家庭来说,大学教育是件新事物。)/ He woke up to find his house on fire.(他醒来发现房子着火了。) / You cannot leave until your work is finished.(在你的工作被完成以前你不能离开)
(2) 副词作状语位置较为灵活;介词短语作状语,位置基本固定;不定式作状语,一般表示目的、结果;从句作状语.
(3) 多个状语相连时,一般先单词、后短语,先地点、后时间,先小概念、后大概念。如:He went ouf of the room at a quarter to 23:00 last night and then disappeared into the dark.(他昨夜22点3刻从房间里出来,然后消失在黑暗之中。) /
(4) 状语还可以用从句来充当,有时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、比较状语从句、让步状语从句、条件状语从句等。详见“状语从句”。
(5) 注意:由于状语属于修饰性的成分,常归入谓语,因此不作为句子的主要成分。
7、宾语补足语:
(1) 补充说明宾语的动作、状态的成分为宾语补足语,常由名词、形容词、动词非谓语形式(不定式、现在分词、过去分词等)、介词短语等充当。如:Call him Jim, please. (请叫他Jim。) / I tried my best to make him happy. (我竭尽所能让他开心。) / Ask her to come to dinner tomorrow. (请他明天来。) / He let the smaller animals bring food to him. (他让小动物们给他带食物来。)
(2) 部分表示位置、方向的副词也可以作宾语补足语。如:Let him in, I tell you! (我跟你说,让他进来!)/ Please put it away. (请把它收起来。)

一、概述
在作谓语的动词用来表示动作(或情况、状态)发生时间的各种形式称为时 态。由于英语属于曲折变化的语言,其动词时态的变化要通过词的曲折词形变化来体现的,因而也就有了现在式、过去式、过去分词式三个基本词形。英语中根据说话的时间不同有时和体的不同,主要有十六这十二种时态可以列表如下:
一般现在时 现在进行时 现在完成时 现在完成进行时
一般过去时 过去进行时 过去完成时 过去完成进行时
一般将来时 将来进行时 将来完成时 将来完成进行时
一般过去将来时 过去将来进行时 过去将来完成时 过去将来完成进行时
这些时态的形式可以用下表来表示,以do 动词为例:
一般时态进行时态完成时态完成进行时态
现在do
doesbe (am, is are ) doinghas doing
havehas been doing
have
过去did be (was, were) doinghad donehad been doing
将来shall do
will shall (will) be doing shall (will) have doneshall (will) have been doing
过去将来should (would) doshould (would) be doingshould (would)
have done should (would) have been doing
下面根据这些时态常用的程度不同分别说明它们的用法。
二、各时态详解
1、一般现在时
一般现在时主要由动词原形表示,但第三人称单数后要加词尾-s,另外be 和have要根据人称的变化使用特殊的形式。一般现在时主要表示经常性的动作或存在的状态,还可用来表示普遍真理。
The Yangtze rises in Qinghai. 长江发源于青海。
Actions speak louder than words. 行动胜于言辞。
We have friends all over the world. 我们的朋友遍天下。
2、现在进行时
现在进行时是由助动词be加现在分词构成的。主要表示现在或现时刻这一阶段正在进行的动作,有时候还用来表示一个最近按计划或安排要进行的动作。
How are things getting on with you? 工作进行的怎么样?
Someone is asking for you on the phone. 有人找你接电话。
They are publishing a new version of the playscript by Taso Yu this autumn.
今年秋天他们要出版曹禺剧作的一个新译本。
3、一般将来时
一般将来时由助动词shall (will)加动词原形构成。它表示将要发生的动作或情况。
They will sit the post-graate examinations next autumn.明年秋他们要参加工硕考试。
The teacher will not let me go home before I have finished my homework.
老师要我做完作业才能回家。
4、一般过去时
一般过去时由动词过去式表示,动词be 根据人称有was和were两个词形,规则动词在词尾加-d-或ed;其他动词参阅不规则动词变化表, 该时态主要表示过去某时发生的动作或情况。
It's a pity that you did not go to the movie. 很遗憾你没有去看那部电影。
Many people died in the tsunami that took place in Thailand.
很多人在泰国的那次海啸中遇难丧生。
5、现在完成时
现在完成时是由助动词have和has加过去分词构成的。主要表示此刻以前曾经发生的动作或情况。如:
Grain output has greatly increased in the past few years. 这几年粮食产量有了很大增长。
The area has suffered from disastrous floods throughout its history.
这个地区历史上一直遭受水患之苦。
注意:过去时和现在完成时的区别:
现完成时的基本特点是它和现在有密切的联系,或是指迄今为止这一段时间的情况,或是过去发生的事对现在造成的影响或结果等。而过去时主要强调过去某时刻所发生的动作或情况,与现在没有任何联系。如:
Up till now we have planted over 10,000 apple trees.
到目前为止我们共种了一万多棵苹果树。
I saw him a minute ago. 我前一会还见到他的。
6、过去进行时
过去进行时是由助动词be的过去式加上现在分词构成的,主要表示过去某个时刻正在进行的动作。
At that time she was working as an assistant in a physics labatory.
那时她在一家物理实验室做助手。
They took us to see the chemical fibre mill that they were building.
他们带我们去参观了他们正在修建的化纤厂。
7、过去完成时
过去完成时由助动词had加动词的过去分词构成,主要表示过去某时刻前业已完成的动作或存在的状态,其实就是指过去的过去。使用时往往要要在从句中或有一个明确的过去时间状语。
Before daybreak they had covered half the distance. 拂晓前他们已经走完了大半路程。
No sooner had the rain stopped than they set out again. 雨一停他们就又上路了。
He had not learned any English before he came to the university.
上大学前他一点英语没学过。
8、一般过去将来时
一般过去将来时由助动词would加动词原形构成,主要表示从过去某一时间角度看以后将要发生的动作。含这个时态的句子常带一个表示“过去某个时间点”的状语。这个状语或是一个短语,或是一个句子。这个时态常用于:宾语从句或间接引语中。例如:
When I thought about it, I wondered what their reaction would be.
当我考虑这件事时,我想知道他们的反应是什么。
She told me that she would go on trip to Europe the next day.
她告诉我,她第二天要去欧洲旅行。
Whenever he had time, he would help his mother with some housework.
无论他什么时间有空,他总是帮他妈妈干点家务活。
No matter how difficult the work was , he would keep on doing it until he accomplished it . 不管工作有多难,他总会坚持不懈地把它干完。
9、一般将来完成时
一般将来完成时由shall (will) + have + 过去分词构成。主要表示在将来某时业已发生的动作。如:
After we finish this text, we'll have learned twenty texts.
这课课文结束后,我们就学了二十课课文了。
By the next month, I'll have finished my task. 到下个月,我将完成任务。
They will have hit the year's target by the end of October.
到十月底他们就可完成全年的指标了。
10、现在完成进行时
现在完成进行时由have(has)been加动词的现在分词构成,表示发生在过去的某个动作延续到现在或刚刚完成,或许还要继续延续。这种时态侧重于这个动作的连续性,或者说不间断性。例如:

主谓一致首先要弄清主语是单数还是复数,然后选择正确的谓语形式,还有就是有些短语是要记住的,遵循就前原则还是就后原则。
名词单复数形式跟单词词性需要平时的积累。
时态处理嘛,平时不怎么注意的,看语感,建议可以多看看电影咯。

时态要看作文类型,冠词看名词的开头元音,
