初中英语语法速记.docVIP

一、冠词基本用法 【速记口诀】 名词是秃子，常要戴帽子， 可数名词单，须用a或an， 辅音前用a， an在元音前， 若为特指时，则须用定冠， 复数不可数，泛指the不见， 碰到代词时，冠词均不现。 【妙语诠释】 冠词是中考必考的语法知识之一，也是中考考查的主要对象。以上口诀包括的意思有：名词在一般情况下不单用，常常要和冠词连用；表示不确指的可数名词单数前要用不定冠词a或an，确指时要用定冠词the；如复数名词表示泛指，名词前有this，these，my，some等时就不用冠词。二、名词单数变复数规则 【速记口诀】 单数变复数，规则要记住， 一般加s，特殊有几处： /s/结尾，es不离后， 末尾字母o，大多加s， 两人有两菜，es不离口， 词尾f、fe，s前有v和e； 没有规则词，必须单独记。 【妙语诠释】 大部分单数可数名词变为复数要加s，但如果单词以/t?蘩/、/?蘩/、/s/发音结尾（也就是单词如果以ch，sh，s，x等结尾），则一般加es；以o结尾的单词除了两人（negro，hero）两菜（tomato，potato）加es外，其余一般加s；以f或fe结尾的单词一般是把f，fe变为ve再加s；英语中还有些单词没有规则，需要特殊记忆，如childchildren，mousemice，deerdeer，sheepsheep，ChineseChinese，oxoxen，manmen，womanwomen，footfeet，toothteeth。三、名词所有格用法 【速记口诀】 名词所有格，表物是“谁的”， 若为生命词，加“s”即可行， 词尾有s，仅把逗号择； 并列名词后，各自和共有， 前者分别加，后者最后加； 若为无生命词，of所有格， 前后须倒置，此是硬规则。 【妙语诠释】 有生命的名词所有格一般加s，但如果名词以s结尾，则只加“”；并列名词所有格表示各自所有时，分别加“s”，如果是共有，则只在最后名词加“s”；如果是无生命的名词则用of表示所有格，这里需要注意它们的顺序与汉语不同，A of B要翻译为B的A。四、接不定式作宾语的动词 【速记口诀】 三个希望两答应，两个要求莫拒绝； 设法学会做决定，不要假装在选择。 【妙语诠释】 三个希望两答应：hope，wish，want，agree，promise 两个要求莫拒绝：demand，ask，refuse 设法学会做决定：manage，learn，decide 不要假装在选择：petend，choose五、接动名词作宾语的动词 【速记口诀】 Mrs. P Black missed a beef bag. （布莱克夫人丢了一个牛肉袋。） 【妙语诠释】 该句话中每个字母代表了一个动词或短语，这些动词要求后面跟动名词作宾语。这些动词分别是： M=mind， r=risk， s=succeed in，P=practice，B=be busy， l=look forward to，a=admit，c=cant help， k=keep on， m=miss，i=insist on，s=suggest，s=stop，e=enjoy，d=delay，a=avoid，b=be worth，a=advise，g=give up。六、不定式作宾语补足语时省to的动词 【速记口诀】 一感，二听，三让，四看，半帮助 【妙语诠释】 一感：feel；二听：hear，listen to；三让：make，let，have；四看：see，notice，watch，ob-serve；半帮助：help。 七、形容词和副词比较等级用法 【速记口诀】 1. 比较级与最高级：两者比较than相连，三者比较the在前。 2同级比较：同级比较用原形，asas永不离；asas加not，只言两者是同一，若是not soas，后强前弱不看齐。 【妙语诠释】 比较级通常和than连用，而最高级通常跟有定冠词the；同级比较一般用asas表示“与一样”，这时谁强谁弱不能比较出来，而not soas则表示后者比前者强，翻译为“不如”。 八、反意疑问句用法 【速记口诀】 反意问句三要点，前后谓语正相反； 短句not如出现，必须缩写是习惯； 最后一点应注意，短句主语代词填。 【妙语诠释】 反意疑问句的构成应该是“肯定的陈述句+否定的疑问”或“否定的陈述句+肯定的疑问”；在短句中not必须与do，will，can等组成缩写形式；在简短问句中，疑问句的主语必须是代词，而不能用名词形式。九、感叹句用法 【速记口诀】 感叹句，并不难，what、how放句前； 强调名词用what，其余用how很简单。 【妙语诠释】 由what引导的感叹句一般修饰名词，而how引导的感叹句一般修饰形容词、副词或句子。十、宾语从句用法 【速记口诀】 宾语从句须注意，几点事项应牢记。 一是关键引导词，不同句子词相异。 陈述句子用that；一般疑问是否（if，whether）替；特殊问句更好办，引导还用疑问词。 二是时态常变化，主句不同从句异。主句若为现在时，从句时态应看意；主句若为过去时，从句时态向前移。 三是语序要记清，从句永保陈述序。 【妙语诠释】 宾语从句应注意三点：引导词，陈述句一般由that引导，这时的that可以省略；一般疑问句则由if或whe-ther引导；而特殊疑问句则由特殊疑问词引导。时态，主句是现在时态，从句可用所需要的任何时态；但如果主句是过去时态，从句时态所表示时间一般往前移一个时间段。语序，宾语从句永远要用陈述句顺序。初中英语语法一般将来时详解和习题一般将来时表示将要发生的动作或存在的状态以及计划、打算做某事。E.g. They will have a football match tomorrow. He will be thirty next week. She is going to buy a coat this afternoon. 其结构有如下几种: 1)will + 动词原形(will可以用于任何人称) 需要注意的是当主语是第一人称时will可以换成shall,特别是在以I或we作主语的问句中,一般用shall. e.g. Shall we go to the zoo? 2)be going to +动词原形 3)现在进行时也可表示将来,前边已经讲过,这里不在重复. 第一种结构的句式变化是: 变否定句在will后边加not. 变一般疑问句把will提前. e.g. She will be back in three days. She will not be back in three days. Will She be back in three days? 第二种结构的句式变化要在be上做文章. E.g. They are going to clean their classroom. They are not going to clean their classroom. Are they going to clean their classroom? 其时间状语有如下几种 1）this引导的短语 如 this year 2）tomorrow及其相关短语如tomorrow morning 3）next引导的短语 如 next month 4) from now on ; in the future ; in an hour 等。 学生常见错误如下：一、易忽视动词用原形形式 例：1 He will is (be) at school next Monday. 2 He is going to does (do) his homework after school. 答案：1 be 2 do 解析：第一题有的同学一看he做主语就用了is，忽视了will后应加动词原形。我们在写句子时，很容易把动词丢掉，“英语句子里，动词不能少”的规律必须要牢记。第二题中to后加动词原形，而不是用单三人称.。二、be going to +动词原形与will+动词原形用法不清楚 例：我正努力学习，准备参加英语考试。 I am studying hard and I will try for my English exams. 答案：I am studying hard and I am going to try for my English exams. 解析：“be going to” 表示计划、打算要做某事。E.g. He is going to visit his friends. 还表示某种迹象表明会发生某事.e.g. Look at the clouds. Its going to rain. 而“Will+动词原形 ”指对将来事物的预见、表示意愿、决心。E.g. I will wait for you until you come. 在单纯预测未来时，二者可以互换，但在此题中只能用be going to，而不能用will。自主检测：（一）、 单选1 _you _a doctor when you grow up?A Will; going to be B Are; going to be C Are; / D Will; be2 I dont know if his uncle _. I think he _ if it doesnt rain.A will come; comes B will come; will come C comes; comes D comes; will come3 He will be back _a few minutes.A with B for C on D in4 What time _we meet at the gate tomorrow?A will B shall C do D are5 He will have a holiday as soon as he _the work next week.A finishes B doesnt finish C will finish D wont finish6 There _some showers this afternoon.A will be B will have C is going to be D are going to have7 It _my brothers birthday tomorrow.

Or we _(be) late.8What _you _(do) tomorrow afternoon?9 Jenny _ _ (do) an experiment the day after tomorrow.10 If she isnt free tomorrow, she _(not take) part in the party.答案： 1 will bring 2 Are 3 wont leave 4Shall go 5 will 6 will go 7 will be 8 are going to do 9 will do 10 wont take三、 There be结构的一般将来时易出错例：There_ a basketball match this afternoon. (B)A is going to be B is going to have C are going to be D are going to have答案：A解析：There be结构的一般将来时既要符合There be结构，又要符合一般将来时。有的同学认为have当“有”讲，所以选了B，但There be结构就不成立了，此句中is是be going to中的，是由后边的单数名词决定的.四、 be going to结构中易丢掉to例：Im going _(go) school by bike tomorrow. (C)A to will go B to go to C go to D to go答案：B解析：由tomorrow可知是一般将来时，be going to +动词原形，所以先确定用to go , 在B、 D当中选，而go to school 是固定词组，不能因为前边有一个to而省略，这是一个易错点，需要注意。 另外，在时间状语或条件状语从句中，若主句用了将来时，从句则用一般现在时，前边已经讲过,这里不在重复.初中英语语法一般过去时详解和习题时间：2009年03月18日 作者：匿名 来源：博客 一般过去时主要表示过去某时发生的动作或情况。可以从以下几个方面来理解：1）过去某个时间所发生的动作或存在的状态。e.g. I bought a new shirt yesterday. He was a worker two years ago.2）过去一段时间内，经常性或习惯性的动作。e.g. When I was a child,I often played with fire.

He is reading . They are talking now.2、当前一段时间内的活动或现阶段正在进行的动作。E.g. They are working these days.3、某些动词的现在进行时，表预定的计划或即将发生的动作。E.g I am coming.其结构为be+现在分词. 现在分词的变法有1、一般在动词词尾加上-ing ,E.g. jump2、以不发音字母e结尾的动词，先去e，再加-ing. E.g have write3、.以重读闭音节末尾只有一个辅音字母结尾的词，它前面是单个元音字母时要先将词尾的辅音字母双写，再加上-ing. E.g. sit put其句式变换都在be上做文章。E.g. He is buying a bike.Is he buying a bike?He isnt buying a bike.一般由look,listen,now, at this moment等时间状语做标志。尽管现在进行时比较简单，但在做题过程中也常会犯一些错误，常见的错误有如下几种：自我检测（一） 、单选1、 Look! He _their mother do the housework.A. is helping B. are help C. is help D.is helpping2 、_are the boys doing ? They are singing in the room.A .Who B .How C.What D.Where3、 Dont talk here. My mother _.A. is sleeping B .are sleeping C. sleeping D .sleep4 、Danny _. Dont call him.A. is writeing B .is writing C.writing D .writes5 、When_he_back? Sorry, I dont know.A. does,come B.are coming C.is come D.is coming答案：A C A B D（二）、填空1、 Its ten oclock. My mother _(lie)in bed.2、 What_he _(mend)?3、 We _(play)games now.4、 What _you_(do) these days?5、 _he _(clean) the classroom?6、 Who_(sing)in the next room?7 、The girl_(like)wearing a sweater. Look! She _(wear)a red sweater today.答案：1 is lying 2 is mending 3 are playing 4 are doing5 Is cleaning 6 is singing 7 likes ; is wearing一、把动词变成现在分词形式易出错例：1、They are swiming.(swim)2 、Jenny is plaiing(play)football.答案：1.swimming 2 .playing解析：动词变现在分词可有如下口诀:“一添一去y不变”. “一添”指双写规则；“一去”指去掉不发音字母e规则；“y不变”指要与名词变复数区分开。二、丢掉be动词或忘记把动词变成现在分词例：1、 Look,two children flying.(fly) a kite in the park.2 、Li Mingisnt read ( not read) a book in bed now.答案：1 are flying 2 isnt reading解析:现在进行时肯定句的结构规律为: “be+现在分词,缺一不可”。这一点必须牢记。三、对动词或动词词组提问时丢掉doing例：1 、The students are singing in the room.(对划线部分提问)What are the students in the room?答案：What are the students doing in the room?解析:现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?”或简写为“What.doing.”?句式。四、现在进行时态的选择疑问句中易忽视or后用现在分词形式例：孩子们在跑还是在跳？Are the children running or jump?答案：Are the children running or jumping?解析: or连接的是两个并列成分，动词形式须一致。初中英语语法一般现在时讲解与习题时间：2009年03月18日 作者：匿名 来源：博客 一般现在时是英语中应用最广泛的时态之一，是初中英语语法重点。它表示1)经常性、习惯性的动作或存在的状态。e.g. I go to school on foot. He is very busy now. 2)表示主语的特征、性格、能力、爱好等。e.g. He can swim. I work hard. I like watching TV. 3)表示客观真理 e.g. There are seven days in a week. The moon moves round the earth. 其结构按正常语序，即“主语+谓语+其它”，有时为了起强调作用，时间状语也可提前. 其句式变化可分为两种情况 1)表示动作， 一般人称作主语的，变否定句须在动词前加助动词dont；变一般疑问句须在句首加助动词do。 E.g. They have lunch at 12:00. They dont have lunch at 12:00. Do they have lunch at 12:00? 2）单三人称做主语的，变否定句须在动词前加助动词doesnt；变一般疑问句须在句首加助动词does。E.g. Jenny speaks English very well. Jenny doesnt speak English very well.Does Jenny speak English very well? 含有be动词的要在be上做变化. E.g. Danny is a good student.Danny isnt a good student. Is Danny a good student?其时间状语为often、 usually、 always、 sometimes等频率副词，on Saturdays、 in the morning(afternoon evening) 、every day 等。 学生常见错误如下：一、be动词与行为动词同时出现在句子中例：We are plant (plant) the trees in spring.答案：plant解析：学生往往会用汉语的思维方式去翻译，就成了“我们是在春天植树”。这是学习英语最忌讳的，要看语法是不是正确，在英语中，be是表状态，do是表动作，两种动词不能同时出现在句子中，可记住如下口诀：“英汉语言有差异，be 、do不能放一起，仔细琢磨细分析，语法千万要牢记。”自我检测：(一)、 单选1 Jenny _ in an office. Her parents _in a hospital.A work; works B works; work C work; are working D is working; work2 One of the boys_ a black hat.A have B there is C there are D has3 We will go shopping if it_ tomor
