❶ 初三英语重点短语和语法

自己整理!!!!

❷ 初三上学期的英语语法有哪些

英语语法以及基础也就是在初中这个阶段就打好基础,如果这个阶段出错,以后很难有所提高版。老师上课时权笔记要认真做,不仅要做,还要把它记在脑海里,通过练习可以得到巩固。初中语法没什么太深的内容,你想想英语语法无非分成时态和语态,如果你基础好就不必花冤枉钱买那么多语法书啃,课堂45分钟十分重要。

九年级英语复习---语法讲解(1-7单元)
Unit1
By是个很常用的介词(有时也用作副词),在初中英语中的用法有以下几种: 1.意为“在……旁”、“靠近”。如: Some are singing and dancing under a big tree . Some are drawing by the lake. 有的在大树下唱歌跳舞,有的在湖边画画儿。 2.意为“不迟于”、“到……时为止”。如: Your son will be all right by supper time. 你的儿子在晚饭前会好的。 How many English songs had you learned by the end of last term? 到上个学期末你们已经学了多少首英语歌曲? 3.表示方法、手段,可译作“靠”、“用”、“凭借”、“通过”、“乘坐”等。如: The monkey was hanging from the tree by his tail and laughing.
猴子用尾巴吊在树上哈哈大笑。 The boy’s father was so thankful that he taught Edison how to send messages by railway telegraph.
孩子的父亲是那么的感激,于是他教爱迪生怎样通过铁路电报来传达信息。 4.表示“逐个”、“逐批”的意思。如: One by one they went past the table in the dark.
他们一个一个得在黑暗中经过这张桌子。5.表示“根据”、“按照”的意思。如:What time is it by your watch? 你的表几点了? 6.和take , hold等动词连用,说明接触身体的某一部分。如: I took him by the hand. 我拉住了它的手。 7.用于被动句中,表示行为主体,常译作“被”、“由”等。如: English is spoken by many people. 英语被许多人所说。(即“许多人讲英语。”) 8.组成其它短语。 1) by the way : 意为“顺便说”、“顺便问一下”,常做插入语。如: By the way , where’s Li Ping , do you know?
顺便问一下,李平在哪儿。你知道吗? 2) by oneself : 意为“单独”、“自行”。如: I can’t leave her by herself. 我不能把她单独留下。 3) by and by : 意为“不久以后”、“不一会儿”。如: But by and by , more and more people began to study English. 但是不久以后,越来越多的人开始学英语了。
二、动名词的构成动词后加动名词doing,相当于名词,在句子中可以做主语、宾语、表语定语等。1)★作主语(这种用法常考)
Fighting broke out between the South and the North.南方与北方开战了。2)作宾语Would you mind turning down your radio a little, please?
请问你介意调小一点收音机的音量吗?3)作表语Babysister’s job is washing,cooking and taking care of the children。保姆的工作是洗衣服,作饭和照看孩子。
Unit2
used to 的用法:(1)肯定句:used这个词没有人称的变化,to后面接动词原形。

否定句是didn’t use to….
When I was a child, I didn’t use to like apples.当我还是孩子的时候我不喜欢苹果.
疑问形式是Did you use to…?Where did you use to live before you came here?当你来这儿之前你住哪儿?
(2)含有used to 的句子的反意疑问句不要usedn’t + 主语,而用didn’t + 主语。He used to smoke, didn’t he? 他过去常常吸烟,是吗?Yes, he did./ No, he didn’t. 是的,他吸。/ 不,他不吸。
(3)used to 表示过去的习惯动作, 而不是现在的。I am used to the weather here. 我已经习惯于这里的天气了。He is used to hard work. 他习惯于艰苦的工作。
(4)used to 可以和be, have 以及其他状态动词连用,描写过去的状态。 I used to be a waiter, but now I’m a taxi-driver.我过去是一个服务员,但现在我是出租车司机。
★ 本单元的许多运用used to 的句子属于描述过去的状态。Mario used to be short.马力奥过去总是很矮。Amy used to be outgoing.爱米过去性格外向。Tina used to have long and straight hair.蒂娜过去有一头直的长头发。He used to wear black shoes. 他过去常穿黑鞋。
Unit3
本单元重点讲到了被动语态的用法英语动词的被动语态由助动词be加及物动词的过去分词构成。助动词be有时态,人称和数的变化,其变化规则与连系动词be完全一样。
 一、被动语态的句式变化: 以一般现在时和动词invite为例,列表说明被动语态的句式变化:

二、各种时态的被动语态结构总结如下: 被动语态的时态是由be的时态决定的,be是什么时态,全句就是什么时态,be动词后面的过去分词不变。一般现在时的被动语态为:主+am / is / are (not)+过去分词一般过去时的被动语态为:主+was / were +过去分词
例如:我们学过的was / were born 生于,就是一个被动语态.born是个过去分词(bear)-When were you born ? -I was born in 1989. 现在进行时被动语态的构成为: 主语+is / am / are + being +过去分词
现在完成时被动语态的构成为: 主语+have / has +been +过去分词
情态动词的被动语态: 情态动词+be+过去分词
一般将来时的被动语态: 主语+will +be +过去分词
过去将来时的被动语态: 主语+would / should + be +过去分词
过去进行时的被动语态: 主语+was / were + being +过去分词
过去完成时的被动语态: 主语+had + been +过去分词
三、被动语态的用法:(1)不知道或没有必要说明动作的执行者是谁,不用by+动作执行者短语 Football is played widely all over the world. 全世界都广泛地踢足球。
(2)强调动作的承受者,这时应用by短语。The bank was robbed yesterday afternoon. 昨天下午这家银行遭到抢劫。
(3)作客观说明时,常采用一种被动语态句型It is reported that about twenty children have died of flu in the USA.
据报道美国大约二十名儿童死于流感。
四、主动语态的句子变为被动语态的方法是:(1)把原句中的宾语变为主语(2)动词改为被动形式,即be+过去分词(3)原来的主语,如果需要的话,放在by后面,如果没必要,可省略。请看下表:
主动语态 被动语态
They make trains in Zhuzhou. They use this key for locking the classroom door.Many people speak English.He wrote a letter.They are building a road. Trains are made in Zhuzhou.This key is used for locking the classroom door(by them).English is spoken by many people.A letter was written by him.A road is being built (by them).

Unit4
虚拟语气:如果我们所说的不是事实,也不是要求、命令、劝告等,而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气
注意:条件句分两种,真实条件句和虚拟条件句。只有在虚拟(非真实)条件句中,才用虚拟语气,而在真实条件句中,要用陈述语气。
请比较:
(1)If it is sunny tomorrow , we’ll go to the zoo.
如果明天天气好,我们将会去公园。在这句话中,明天天气好是完全有可能实现的,并非虚拟、幻想,因此是真实条件句。在本句中,适用“主将从现。”
(2)If I were you , I would go at once.
(如果我是你的话,我立刻就走。)在这句话中,条件句,“如果我是你”,但事实上,我不可能成为你,这只是假设的情况,没有实现的可能。当条件实现的可能性很小,甚至可以说没有时,就需要用虚拟语气来表示,动词发生了变化。
也就是说虚拟语气表示和现实的事实相反时,从句用一般过时。
主句用 “should/would/could/ might +动词原形。
1.If I had time, I would go for a walk.
2.If I were invited, I would go to the dinner party.
3.If I won a million dollars in the lottery, I would put it in the bank.
知识点2. He doesn’t know if he should bring a present.
此处if表示“是否”,引导宾语从句。Should此处表示“应该”。不是虚拟语气。
E.g.1. I don’t know if I should go to the party.
2.If I have enough money, I will go to Hainan .
知识点3.If I were you , I’d wear a shirt and tie.
if 引导的条件状语从句表示与现在事实相反的虚拟语气时,be动词只能用were,而不能用was。
E.g. If he were here, he would not agree with you .
知识点4. I don’t have a present. What if everyone else brings a present?
What if… “如果……怎么办?”相当于 what would happen if…
E.g. What shall I do if it snows?
知识点5.Well, dogs can be a lot of trouble.
Trouble 麻烦事 ,名词
常用搭配 :get (sb)into trouble get out of trouble what’s the trouble
“if”引导的条件句。

Unit5
It must be--- (肯定是,100%)
It might/could be… (有可能,20-80%)

Unit6
定语从句
1. who 指人,作主语或宾语 (作宾语可省略)
The man who I talked with is our teacher.
A person who steals things is called a thief.
2. whom指人,作宾语 (作宾语可省略,如介词提前则不能省)
The man (whom/who) I nodded to is Mr. Li.
The man to whom I nodded is Professor Li.
3. which 指物,作主语或宾语 (作宾语可省略, 如介词提前则不能省)

This recorder (which) he is using is made in Japan.
Is this the library (which) you borrow books from?

He is the kind person that I have ever worked with.
who
whom
Ø

This is the best film that I have ever seen.
Ø
在选择引导定语从句的关系代词时,有如下要点:
1 由于关系代词在主句与从句间既起到联系作用,又在从句中充当一个成分,因此, 要正确判断关系代词在从句中的功能,如作主语还是宾语等。
2 当先行词指人时,关系代词可用who(做主语,宾语),that(做主语,宾语),whom(作宾语),whose(作定语)
3 当先行词指物时,关系代词可用that(做主语,宾语),which(做主语,宾语)
4 再定语从句中,作宾语的关系代词长可省略,但在介词后面的关系代词不能省略。指人时,介词后只用whom,指物时,介词后只用which。
5 在非限制性定语从句中,指人时,只用who,指物时,只用which。
1.定语从句中that与who、which的区别

 

2.定语从句中关系词的省略

 

 典型例题
1. The first job ________I found was to be a cleaner.
A. where     B. why      C. which     D. that
解析:指事物的先行词前有序数词修饰时,只能用关系代词that。故本题的正确答案是D。
2. I don’t think history is as interesting as English.(改为同义词)
I think history is ___________ interesting _________ English.
解析:答案是:less; than。意思是“我认为历史不如英语有趣”。
3. The woman who is wearing the hat is my mother.(改为同义句)
The woman ________ the hat is my mother.
解析:读题后可知:上句含义是“戴帽子的那个妇女旭我的妈妈”,对应下句,可知空格处应填“戴”,故正确答案是in。
选择填空
1. The poor boy ________ lost both his parents last year is called Mike.
A.which    B.what    C.who    D./
2. The bridge ________ has been there for nearly fifty years still looks nice.
A.which    B.what    C./    D.who

九年级英语复习---语法讲解(Units8-15)
Unit8
1、短语动词小结
常见短语动词结构有下面几种:
1.动词+副词 如:give up 放弃 turn off 关掉 stay up 熬夜
这种结构有时相当于及物动词,如果其宾语是代词,就必须放在动词和副词之间,如果是名词,则既可插在动词和副词之间,也可放 在短语动词后。
2. 动词+介词 如:listen of 听 look at 看 belong to 属于
这种结构相当于及物动词,后面跟宾语。
3. 动词+副词+介词 如:come up with 提出,想出 run out of 用完,耗尽
4. 动词+名词(介词) 如:take part in参加 catch hold of 抓住
2、倒装句
not only … but (also) … 不但… 而且… 用来连接两个并列的成分
(1)引导以 not only …but (also)… 开头的句子往往引起部分倒装。
因此 ⑴Not only do I feel good but (also)…. 是倒装句。也是说得要
把前面的句子中的助动词或者是情态动词放在主语的前面。如:
①Not only can I do it but (also) I can do best. 我不仅能做到而且做得最好。
⑵Not only…but (also)… 接两主语时,谓语动词随后面的主语人称和数的变化 也就是就近原则 如:
①Not only Lily but (also) you like cat. 不仅莉莉而且你也喜欢猫。
②Not only you but (also) Lily likes cat. 不仅你而且莉莉喜欢猫。
常见的就近原则的结构有:
Neither… nor…即不…也不… (两者都不)
Neither you nor I like him. 我和你都不喜欢他。
Either… or… 不是…就是… (两者中的一个)
Either Lily or you are a student.
Not only …but (also)…
There be

❺ 初三上学期英语语法和固定用语总结

你好~!
这个文件量太大了,你可以把邮箱告诉我,我会尽快发送到你的邮箱~!

❻ 谁可以帮我归纳初三上学期的英语语法和句型啊。。急!是新课标的版本。。

1、并列句基本概念:

并列复合句是由两个或两个以上并列而又独立的简单句构成。两个简单句常由并列连接词连在一起;但有时不用连接词,只在两个简单句之间用一逗号或分号。

2、常见的并列句:

(1)用来连接两个并列概念的连接词有and,not only…but also…,neither…nor…等,and所连接的前后分句往往表示先后关系、递进关系。前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。

(2)表示在两者之间选择一个,常用的连接词有or,otherwise,or else,either…or…等,前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。

(3)表明两个概念彼此有矛盾、相反或者转折,常用的连接词有but,yet,still,however等,前后分句时态一致。

(4)说明原因,用连接词for,前后分句时态一致。

(5)表示结果,用连接词so,前后分句时态一致。

主从复合句

1、概念:

主从复合句由一个主句和一个或一个以上的从句构成。主句为句子的主体,从句只用作句子的一个次要成分,不能独立成为一个句子。从句通常由关联词引导,并由关联词将从句和主句联系在一起。如:While the grandparents love the children, they are strict with them.(爷爷奶奶们很爱孩子,同时对他们也严格要求。)/It seemed as if the meeting would never end.(看起来会议没完没了。)/Hurry up,or(else) you'll be late.(快点,要不然就来不及了。)/However I cook eggs,the child still refuses to eat them.(不管我用什么方法煮鸡蛋,小孩还是不肯吃。)

2、分类:

从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。(参见以下各条)

3、各从句在句子中的位置以及用法:

(1)表语从句:在句子中作连系动词的表语的从句,它位于主句中的系动词之后。

例如:That is why he did not come to school yesterday. / It is because you are so clever.

(2)宾语从句:在句子中作及物动词或介词的宾语。

①基本形式:(主句+)连词+从句主语+从句谓语+...

②关于宾语从句连词的选择:

若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;

若从句来源于一个一般疑问句,连词则用if或whether;

若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)

例如:They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。)(从句本来就是陈述句) / I wonder whether I should say something for him to the headmaster.(我不知道是不是该为他在校长跟前说点什么。)(从句来源于一般问句 Shall I say something for him to the headmaster?) /He asked me where he could get such medicine.(他问我在哪儿能搞到那样的药。)(从句来源于特殊问句Where can he get such medicine?)

③宾语从句的时态问题:如果主句是现在时,从句则用现在某一时态,甚至可以用过去时;

如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如:I think I will do better in English this term.(我想本学期我的英语会学得好点。)/The teacher asked the boy if the earth is round.(老师问那个男孩地球是不是圆的。)

④下列结构后面的从句一般也作为宾语从句看待:

Be sorry/afraid/sure/glad+that从句,如:I'm sorry I'm late.(对不起,我迟到了。)/I'm afraid he isn't in at the moment. (恐怕他此刻不在家。)

(3)状语从句:在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原因、目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。

时间状语从句通常由when,as,while,after,before,since,assoonas,since,till(until),while,whenever等引导。时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。如:When you finish the work, you may go out to play with Sam.(你完成工作就可以出去和Jim一起玩了。)/I won't leave until Mum comes back.(妈妈回来了我才会走。)

地点状语从句通常由where,wherever等引导。如:Go back where you came from!(哪里来还滚到哪里去!)/I will never forget to catch the thief who stole my necklace wherever he may be.(我永远也不会忘记去抓住那个偷我项链的贼,无论他会在哪里。)

原因状语从句通常由because,since,as等引导,一般放在句首或句尾。如:He went abroad because his father had found a good university for him.(他出国了,因为他父亲给他找了一所好大学。)

目的状语从句通常由sothat...,so...hat...,inorderthat...等引导,往往放在句尾,从句中通常含有can/could/may/might等情态动词。如:He got up earlier so that he could catch the first train.(他起身更早为的是赶上第一班车。)

结果状语从句通常由sothat...,so...that...等引导,放在句尾。结果状语从句一般表示已经发生的事情,故多为过去时态。如:He lost so many bikes that he decided never to buy a new one.(他丢了那么多辆自行车,他决定再也不买新车了。)

比较状语从句通常由as,than,as(so)...as等引导,一般省略从句的谓语部分,只剩下名词或代词(用主格或宾格均可)。如:Jane is much taller than I/me.(Jane比我高多了。)/I don't have as many books as you (do).(我书没有你多)

让步状语从句通常由though(although),as,evenif(eventhough),however,whatever等引导。如:Evenifyoupaythedebt(债务)for me, I will not thank you because it has nothing to do with me.(即使你替我还了债我也不会感谢你,因为它与我毫无关系。)/He wears a T-shirt though it is very cold.(他穿了一件T恤衫,尽管天很冷。)

条件状语从句通常由if,unless,aslongas等引导,条件状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。You will certainly fail in the coming final exams unless you work much harder.(即将来到的期末考试你肯定考不及格,除非你更用功。)/If it doesn't rain tomorrow, we shall go hiking.(如果明天不下雨我们就要去徒步旅行。)

[注意]1、because与so;(al)though与but;if与so不可以同在一个句子中成对出现。

2、时间、条件、原因,让步状语从句放在句首时需要用逗号与主句隔开。

(4)定语从句:在复合句中作定语用修饰句子中某一名词或代词的从句叫定语从句。

①定语从句的位置:放在名词或代词的后面。如:The man who has an umbrella in his hand is my uncle.(手上抓了一把雨伞的人是我的叔叔。)

②语法术语的改变:被修饰的名词或代词称为先行词;引导定语从句的连接词称为关系词,其中that、which、who称为关系代词,where、when、how称为关系副词。

③关系代词或关系副词的作用:

关系代词who、whom和whose指人,分别在从句中作主语、宾语和定语。which指物that多指物,有时也指人,它们在从句中可以作主语或宾语。定语从句中关系代词作从句宾语时可以省略。This is the thief (that/who/whom) we have been looking for these days.(这个就是我们近日一直在找的小偷。) /Please find a room which is big enough for all of us to live in.(请找一间足够大能住下我们全体的房间。)

关系副词when或where引导定语从句时,它们在从句中分别作时间状语和地点状语。如:This is the room where they had a quarrel a week ago.(这是一个星期前他们吵架的房间。)/I can never forget the day when I first saw you.(我永远不会忘记第一次见到你的日子。)

④限制性定语从句和非限制性定语从句。限制性定语从句在句中不能省略,否则主句意思就不完整。非限制性定语从句和主句之间往往用逗号分开,这种从句是一种附加说明,如果从句子中省去,也不致于影响主句的意思。如:She spent the whole evening talking about her latest book, which none of us had heard of.(她一个晚上都在谈论她最近的书,我们一个人都没有听说过那本书。)

[注解]

1、关系代词只能用that的情况:

当先行词是指事物的不定代词(all,anything等),或先行词部分含有最高级,或含有序数词时,不能用其他的关系代词,只能用that.如:All that Lily told me seems untrue.(Lily告诉我的话似乎不真 实。) /Can you give me anything that has no sugar inside? (能不能给我点里面没有糖的东西?) /This is the first two-story bus that runs in our city.(这是第一辆运行于我市的双层公交车。)

2、关系代词在从句中作主语时一般用who(指人)、that(指物),而不用that指人或用which指物。

如:Do you know the woman who is weeping in the corner?(你认识那个在角落里哭泣的女人吗?)/Do not tell me any words that have nothing to do with me.(跟我无关的话,请一个字也不要说。)

3、关系代词作从句的宾语时,常用which或whom,较少使用that或who,而且,关系代词常常省略。

如:Tom's father was the first parent whom our teacher talked to. (Tom的父亲是我们老师第一个谈话的人。)

4、当关系代词紧跟在介词后面时,必须用which或whom,而当介词移到句尾时,则又可以使用that或who.

如:This is the room in which Miss Lionce lived. (=This is the room Miss Lionce lived in.) (这是李小姐曾经居住过的房间。)

(5)主语从句:在句子中充当句子主语的从句叫主语从句。位于谓语动词之前。通常由that,whether以及疑问连词引导。一般情况下,常用it替代主语从句,而将主语从句移到句尾。如:When we should start is still a question.(我们该在什么时候开始还是个问题呢。)

直接引语和间接引语

1、直接引语和间接引语:在陈述句中,直接引用说话人原来的语句,称为直接引语。在书写时,直接引语用引号。用自己的词语来转述表达原来说话人说的内容,称为间接引语。

2、直接引语改变为间接引语:

1、直接引语如果是陈述句,变为间接引语时应注意以下各点:

①不用引号,而用连接词that,但有时可省略。

②人称作相应变化;

③主句里的动词如果是过去时,间接引语中的时态一般应作相应改变:一般现在时变一般过去时;一般将来时变过去将来时;现在进行时变过去进行时;现在完成时变成过去完成时;一般过去时变成过去完成时;但一般过去时如与一个具体的过去时间连用,则时态不变。

如:He says,

4.前后缀构词法(re-, in(m)-, un-, dis-, anti-, -able, -ful, -less)
1.-able 以“-able”结尾的形容词一般有两种情况:
(1)v.+able→adj. 以这种方式构成的形容词其意义为“能……的”、“可以(被)……的”、“适 合于……的”、“值得……的”等,即有被动含义。例如:reliable(可以依靠的),drinkable(可以饮用的 ),eatable(可食用的)。
(2)n.+able→adj. 这种形容词意为“具有……特点的”,如valuable(有价值的),reasonable( 有道理的),comfortable(舒适的)。
2.-ible 该词缀在意义上与“-able”相同,但主要用于拉丁语后。例如:terrible,horrible,invi sible,possible。
3.-al 该词缀大多是加在名词后形成形容词的。不过,有些“-al”后缀则仅体现了该词的形容词性 ,并非以这种方式构成形容词。“-al”意为“属于……的”、“有……特性的”。这类词在中学英语中颇多 ,如actual,general,international,medical,mental,moral,natural,official,several,special,usual。( 这类形容词大部分没有比较级和最高级)
4.-an “-an”加在国名、地名之后,表明是相应的形容词,如American,African。
5.-ian “-ian”与“-an”相同。例如:Asian,Australian,Canadian,Indian,Italian。
6.-ant “-ant”表示“……性的”。带“-ant”后缀的形容词其相应名词往往是-ance或-ancy后 缀。例如:instant(instance),distant(distance),important(importance),brilliant(brilliancy),consta nt(constancy),pleasant。
7.-ent “-ent”与“-ant”非常相似。例如:absent(absence),different(difference),excelle nt(excellence),patient(patience),present(presence).
8.-ar “-ar”意为“……的”、“……性的”,如popular,particular,regular。
9.-ary “-ary”意为“……的”、“与……有关的”。例如:contrary,necessary,ordinary,prim ary,revolutionary。
10.-ed “-ed”加在动词之后形成形容词。实际上该形容词是由原动词的过去分词演变而来的,因 此它有被动含义。这种形容词在中学英语中出现很多,有connected,discouraged,disappointed,engaged,exc ited,interested,limited,married,pleased,tired,united,used(习惯的),worried,wounded。
“-ed”也可加在动词之后形成复合形容词,如man-made,water-covered。
“-ed”还可加在名词之后形成复合形容词,如warm-hearted,warm-blooded,three-legged。
11.-en “-en”有两种情况:
(1)“-en”跟在一些物质名词之后构成形容词,表示“材料”或“质地”,如wooden,golden,earthe n。
(2)“-en”也可加在一些不规则动词之后形成形容词。这些形容词实际上是由过去分词转换而来的。 例如:spoken,written,stricken,mistaken。
12.-ern “-ern”加在表示方位的名词之后,表示“……(方位)的”。这样的词有eastern,sout hern,western,northern等。
13.-ese “-ese”加在国名、地名之后构成相应形容词。例如:Chinese,Japanese.
14.-ful 这一后缀有两种情况:
(1)加在名词之后构成形容词,表示“充满……的”、“有……性质的”,如beautiful,colourful,he lpful,powerful,successful,useful,wonderful。
(2)加在动词之后,所构成的形容词意为“易于……的”,如forgetful。
15.-ic “-ic”常常加在名词或依附于词干后,构成形容词,意为“……的”、“……似的”、“ 与……有关的”等。例如:Atlantic,electric,arctic,historic,pacific,plastic,public,scientific。
16.-ical “-ical”同“ic”一样附加在名词或词干后构成形容词,意为“……的”、“……似的 ”、“与……有关的”,如physical,political,practical,technical等。
注:(1)有些形容词的词尾可能是“-ic”和“-ical”并存,且可以互相替代,但这不是说两者就没 有任何区别。一般来说,词尾“ic”与词根的关系比较密切,而词尾“ical”与词根的关系比较含糊,一般作 “与……有关的”解。请比较:an electric light(电灯),electrical engineering(电气工程);histo ric意为“历史上有名气的”,historical则意为“关于历史的”。(2)以“ic”结尾的形容词,其相应副词 则往往是pacifically,scientifically。
17.-ing 词尾“-ing”也可构成形容词,但这种形容词实际上是现在分词形容词化了,因此,此类 形容词表示主动。例如:dying,exciting,inspiring,interesting,freezing,living。
另外,“-ing”词尾还可构成合成形容词,如good-looking,ordinary-l
18.-ish “-ish”意义较多,在中学英语中,其主要意义是“……民族的”、“……语的”、“… …似的”、“患……的”,如English,British,foolish,feverish。
19.-ist “-ist”表示“……主义的”、“信仰……的”。该后缀加在名词之后,如communist,im perialist,Marxist,socialist。
20.-ive “-ive”意为“……的”、“与……有关的”、“具有……性质的”等。例如:native,a ctive,passive,attentive,expensive。
21.-less “-less”加在名词、动词后,表示“无”、“缺”,如fearless,harmless,useless,he lpless,careless。
22.-ly “-ly”加在名词之后构成形容词。这一词缀的意义有二:
(1)“像……的”、“有……性质的”,如friendly,lively,lovely,lonely,orderly。
(2)“以……为周期的”、“每……的”,如hourly,daily,weekly,monthly,yearly。
注:如是形容词之后加“-ly”,则构成副词。上述(2)中的形容词亦可用作副词。
23.-(i)ous 该形容词后缀意为“充满……的”、“具有……特征的”,加在名词、动词和形容词 之后。例如:curious,famous,dangerous,obvious,poisonous,serious,various。
24.-some “-some”加在名词、动词之后,表示“使人……的”、“易于……的”,如handsome,t roublesome,tiresome。
25.-ward 它加在名词之后,表示方向,作“向……(方向)的”、“来自……(方向)的”解。例 如:eastward,southward,westward,northward,forward,backward,inward,outward,upward,downward。
注:这些词也可以是副词。如果词尾是“-wards”时,派生词必然是副词。
26.-y “-y”加在名词之后,表示“具有……特征的”、“多……的”。例如:funny,lucky,shab by,snowy,thirsty,windy,sunny,rainy,cloudy,dirty,sty。
以上是中学英语中出现的主要形容词词缀。还需说明的一点是,大部分形容词是从完整的单词上加后缀派 生来的,而有些则是在拉丁词或希腊词的词根上派生来的5.定语从句(that,which,who,whose引导的定语从句,引导词的省略)
6.冠词与数字
定冠词和不定冠词和不用冠词
1.不定冠词的基本用法
(1不定冠词有a和an两种:a用于辅音音素开头的词前,an用于元音音素开头的词前。例如:a boy, a city, a girl, a useful animal , an old man, an honest boy, a bad apple, a tall elephant
(2用来表示“—”的意思,但不强调数的观念,只说明名词为不特定者。即不具体说明是何人何物。例如:A teacher is looking for you.We work five days a week.
(3)不定冠词含有“—”的意思,但数量观念没有one强烈,在句子里边一般可以不必译出,但若有“一个”的意思则译出,例如:
—— An orange is good for you. 桔子对你有好处。
—— How much is it ? 多少钱?
——Two yuan a kilo. 二元一公斤。
(4)一般用在可数名词单数前,指人或事物的某一种类。例如:Bill is a student.
Pass me an apple, please.
例外:I have never seen such a fine film.
(5)用在某些固定词组中。例如:a lot of, a moment ago, a few, a little

2. 定冠词的用法
(1)特指某(些)人或某(些)事物。 例如:The book on the desk is mine.
Show me the photo of the boy, please.

这儿有一些狗。这些狗很可爱。
(4)用在世界上独一无二的事物前。例如:The sun is bigger than the moon.太阳比月亮大些。
但这些名词作为描绘性定语时,可用不定冠词。例如:Look! A red sun is rising. 瞧!一轮红日正在升起。
(5)用在序数词和形容词最高级前。例如:The first island is the biggest of the three.第一个小岛是三个中最大的。
(6)用在用普通名词构成的党派,国家等专有名词以及江河、海洋、山脉、群岛、海峡、海湾等专有名词前。例如:They will visit the Great Wall next week.
They came to the United States of America last year.
The Communist Party of China was founded on July 1st, 1921.
The Yellow River is the second longest river in China.
(7)用在形容词前表示一类人,the +形容词指的是一群人,是一种复数含义,所以其后动词应用复数形式。例如:The old are sick.
(8)用在姓名复数形式前表示一家人。例如:The Smiths have moved to London.
(9)用在某些习惯用语中。例如: in the morning, on the left, the day before yesterday, all the same
三、不用冠词的情况

Today is Father’s Day. 今天是父亲节。
If winter comes, can spring be far behind? 冬天来了,春天还会远吗?
但是如果被一个限制性定语修饰或有表示继续的介词ring, through时与表示一段特定的时间,则在季节前要加定冠词。例如:She came to Shanghai in the spring of 1987.她是一九八七年春天来上海的。
The school was completed in the September of 2000.这学校是2000年9月落成的。
He swims every day ring the summer. 他夏天的每一天都游泳。
虽不特指某一年的季节,但说话人把某季节看作一年的一部分,即一年的某一段时间。则在季节前要加定冠词。例如:We play football in the winter.
(2)在称呼语或表示头衔的名词前。例如:Mr. Li is our headmaster. 李先生是我们的校长。
After lunch Aunt Huang came in. 午饭后黄阿姨来了。
(3)各词复数表示一类人或事物时。但若各词复数被一个限制性定语修饰,则要加定冠词the. 例如:I like cakes very much. 我非常喜欢蛋糕。
My father and mother are the doctors in People’s Hospital of Shanghai.
(4)在三餐饭,球类运动与棋类游戏,学科名称的名词前。但若表示某一种或某一个特定的概念时用冠词。例如:He had supper with us yesterday. It’s a very good supper. 他昨天和我们吃晚饭,这是一顿丰盛的晚餐。
