㈡ 九上英语语法时态的重点
过去完成时态和宾语,定语从句。
㈢ 英语语法的九大时态
一. 一般现在时的基本用法 1. 表示经常发生的动作或存在的状态 常和always, usually, often, sometimes, every day, every week 等时间状语连用。 He is often late. He goes to work every day. Do you drive? He teaches English. 2. 表示普遍真理 由于是众所周知的客观事实,所以一般不用时间状语。 The earth is roun. 3. 有些表示心理状态或感情的动词往往用一般现在时表示。 I want your hel I don’t think you are right. Does ithurt? 疼吗? 4. 在时间。条件状语从句中表示将来要发生的动作。 If it doesn’t rain tomorrow, We’ll go to the Summer Palace. When he gets to the village, he will write to me. 5. 表示已经预先计划或安排的肯定要发生的动作 主要用于come, go, start, begin, leave, return, stop 等瞬间动词,句中常有表示将来时间的状语。 Next week they leave for Shanghai. Our holidays begin in a week. 6. 其他 Here comes Li Ming! There goes the bell. Here he comes. 二. 一般过去时的基本用法 1. 带有确定的过去时间状语时,要用过去时 如:yesterday, two days ago……, last year……, the other day , once upon a time just now in the old days , before liberation, When I was 8 yeas old Did you have a party the other day? Lei Feng was a good soldier. 注意:当谈已死去的人的情况时,多用过去时。 2. 表示过去连续发生的动作,要用过去时 这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。 The boy opened his eyes for a moment, looked at the captain, and then died. 3. 表示过去一段时间内经常或反复的动作 常与always, never 等连用。 Mrs. Peter always carried an umbrella. 比较:Mrs. Peter always carries an umbrella. ,listen来表示now这一时间概念。 Look! A train is coming. Listen! He is playing the piano. 2. 表示现阶段正在进行着的动作 常和at present ,this week,these days……等时间状语连用。 What lesson are you studying this week? 注意:如果没有表示将来时间的状语,此类句子就可能指现在或现阶段的动作。 Where are you going next week? 3. 现在进行时有时可用来表示一个在最近按计划或按排要进行的动作 即可以用来代替将来时,此时一般要与表示将来的时间状语连用,而且仅限于少量动词。 如:go,come,leave,start,arrive,return,sleep…… Are you going to Tianjing tomorrow? How many of you are coming to the party next week? 4. be going to+动词原形: 这一句型表示即将发生的事或打算做的事,我们把它归在将来时里了。 She isn’t going to speak at the meeting. 5. 没有进行时的动词: 表示状态. 思想. 感情和感觉的动词不能表示正在进行的动作 表示感觉的感官动词 例如:see. hear. notice等动词。我们不能说: I’m hearing the sound.I hear the sound. Are you hearing the noise of a plane?Do you hear the noise of a plane? 但是,如果hear不表示“听见”的意思时,可用进行时。 They are hearing an English lecture. 他们在听一个英语讲座。 表示态度和感情. 心理状态. 继续等意思的动词 如:like . Love . Know . Want . Hope . Hate . Think . Agree . belive 等。 I’m liking dogs.I like dogs. . have 当“拥有”讲时 I’m having a lot of books.I have a lot of books. 但当have当“吃饭. 开会……玩的愉快……”等意思时,可用进行时。 We are having a good time. 6. 一般现在时和现在进行时的区别 一般现在时表示经常性的动作,而现在进行时表示暂时性的动作。 He walks to work. He’s walking to work because his bike is being repaired. Where does he live? Where is he living ? 现在进行时有时可以代替一般现在时,表达说话人的某种表情,句子有强烈的感情色彩。常与always, forever连用。 You are always forgetting the important thing. Mary is doing fine work at school. 7. 过去进行时 过去进行时主要表示过去某一个时刻或某一阶段正在进行的动作,常和表示过去时间的状语then, at this time, yesterday, at night, last night等连用。但在不少情况下,没有表示时间的状语,这时需要通过上下文来表示。 What were you doing at nine last night? I was visiting a friend of mine most of the afternoon. 当两个一长一短的动作在过去某时间同时发生时,用过去进行时表示较长的动作,过去进行时可用于主句,也可用于从句。注意:当两个延续动作同时并列时,二者都可用进行时表达。 It was raining hard when I left my office. When you called, I was eating. When I was cleaning the windows, my brother was sweeping the floor. Some students were playing football while others were running round the track. We were walking along the river whenit rained. They were watching TV when the lights went out. 过去进行时表示将来的动作 现在进行时可以表示将来的动作,同样,过去进行时也可以表示从过去某一时间看将来发生的动作。常用在间接引语中。 She went to see Xiao Li. He was leaving early the next morning. She asked him whether he was coming back for lunch. 过去进行时和一般过去时的区别 过去进行时表示过去某时正在进行的动作,而一般过去时则表示一个完整的动作, 也就是说用一般过去时,只表示有过这件事,用过去进行时,则强调了动作的连续性。 Li Ming washed the dishes. 李明洗过盘子了。 Li Ming was washing the dishes. 李明在洗盘子。 The children watched TV yesterday evening. 晚上孩子们看了电视。 The children were watching TV yesterday evening. 孩子们整晚都在看电视。 I was reading a novel this morning. 上午我在看小说。 I read a novel this morning. 上午我看了一本小说。 四. 一般将来时态 一般将来时表示在将来某个时间要发生的动作或存在的状态,常与表示将来的时间状语,如tomorrow, tomorrow morning / afternoon / evening, next week / month / year等连用。 “助动词will + 动词原形”用在疑问句中,当主语是第一人称I或we时,常用助动词shall。 “be going to + 动词原形”表示即将发生某事或计算计划要做某事。 come, go, start, move, sail, leave, travel等动词常用进行时态表示计划将要发生的事。 在时间状语从句和条件状语从句中,用一般现在时表示将来要发生的事。 will和be going to用法区别 1.表示“带意愿色彩的将来”常用will;在问对方是否愿意或表示客气的邀请或命令时,常用will;表示客观将来,用will; I will be twenty-two years old next year. 我22岁。 2.be going to常用于口语中,主要用来表示即将发生的动作或存在的状态;打算或准备要做的事;根据某种迹象判断可能将要发生某事。
㈣ 人教版初三英语上册语法重点,主要是时态。。
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。

2. whom指人,作宾语 (作宾语可省略,如介词提前则不能省)

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
3. I’m one of the students _______well in English in my class.
A.who does B.who do C.which does D.who did
4. Is this factory ________ some foreign friends visited last Friday?

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)…

㈤ 初中九年级英语语法,时态
英语是时态总共就那么几种,你记住了套就可以了.
大类的话就是,现在,过去,将来
现在时:一般现在时,现在进行时,现在完成时
过去时:一般过去时,过去进行时,过去完成时
将来时:一般将来时,
㈥ 英语语法时态
they 与 them 要分清,来they 一般用作主语,源放在句首,them做宾语,放在动词后面。
原句 They are waiting for you (at the library) .可看出they在句中做主语,因此提问时不能用them。
看看这个例子:Are you waiting for them?你在等他们吗?
谓语动词是除开be动词以外的其他所有行为动词的一般现在时变疑问句时用do,如果是第三人称单数,用does。当谓语动词是be或把be当助动词时就用be了。
比较一下这两个句子:
Are you running?你正在跑步吗?
Do you like running?你喜欢跑步吗?
be going to do 是指去做某事
be going to someplace(sp.) 是指去某地方
be going to sp. to do sth. 去某地做某事
