知识点睛：动词主要了解be动词、情态动词和实义动词，这里主要讲解动词在各种时态中的变化规则。

1、一般现在时：一般现在时的构成（1）be动词：主语+be(am， is， are)+其它；如：I am a boy. 我是一个男孩。

（2）行为动词：主语+行为动词(+其它)；如： We study English. 我们学习英语。

注意：当主语为第三人称单数(he， she， it)时，要在动词后加“-s”或“-es”。

如：Mary likes Chinese.玛丽喜欢汉语。

动词+s的变化规则（1）一般情况下，直接加-s，如：cook-cooks， milk-milks；（2）以s. x. sh. ch. o结尾，加-es，如：guess-guesses， wash-washes，watch-watches， go-goes；（3）以“辅音字母+y”结尾，变y为i，再加-es，如：study-studies；2、一般过去时：动词的过去式的构成规则有：（1）规则动词①一般直接在动词的后面加ed：如worked ， learned ， cleaned ， visited；②以e结尾的动词直接加d：如lived ， danced ， used；③以辅音字母加y结尾的动词要改y为i再加ed(此类动词较少)如study –studied carry – carried worry–worried (注意play、stay不是辅音字母加y，所以不属于此类)；④双写最后一个字母(此类动词较少)如stopped；（2）不规则动词(此类词并无规则，须熟记)小学阶段要记住以下动词的原形和过去式：sing – sang ， eat– ate ，see – saw ， have – had ， do – did ， go – went ， take – took ， buy – bought ， get –got ，read – read，fly – flew ， am/is – was ，are – were ， say – said ，leave – left ， swim – swam ， tell – told ， draw – drew ，come – came ， lose– lost ， find – found ， drink – drank ， hurt –hurt ， feel – felt；3、一般将来时：基本结构：（1）be going to + do;（2）will+ do. be going to = willI am going to go swimming tomorrow(明天). = I will go swimming tomorrow.4、现在进行时： am，is，are+动词现在分词；动词的ing形式的构成规则：（1）一般的直接在后面加上ing ，如doing ， going ， working ， singing ，eating；（2）以e 结尾的动词，要先去e再加ing，如having ， writing；（3）双写最后一个字母的(此类动词极少)有：running ， swimming ，sitting ， getting；知识点冲刺训练一、单项选择1．( )She ____ curly black hair and ____ glasses.A.wear; hasB.has; wearC.has; wears2．( )We're going to ____ the Eiffel Tower.A.lookB.watchC.see3．( )My mother ____ me ____ my school by car every day.A.took; toB.takes; toC.takes; for4．( )He ____ English because he was ill.A.didn't go to studyB.doesn't go to studyC.went to study5．( )—____ your father ____ at home?—No, he ____ in a factory.A.Is; work; workB.Does; work; worksC.Is; works; works6．( )—I ____ a present for you.—Thanks a lot.A.gaveB.sentC.bought7．( )—What ____ he look like?—He is tall.A.isB.doesC.are8．( )—Where are the students?—____ in the playground.A.She'sB.There areC.They're9．( )____, everyone.

小升初语法句子的应用专项练习题参考答案与试题解析一．句型转换（共40小题）1．用be （am / is / are ）动词填空Linda is in a red dress．【分析】琳达穿着一件红色的连衣裙．【解答】本题考查主谓一致．根据题干：主语Linda是第三人称单数，谓语动词用第三人称单数形式is．故答案为：is．【点评】做主谓一致题，首先要确定句子主语，然后再根据主谓一致的原则判定谓语的使用．2．用be （am / is / are ）动词填空I am an English teacher．【分析】我是一名英语老师．【解答】考查主谓一致．主语I是第一人称单数，所以be动词为am．故填：am．【点评】在一般现在时中，be动词包括am，is，are．am只跟在主语是第一人称单数I 的后面．is用于第三人称单数后，are用于第二人称以及复数人称的后面．3．Lily gives her friend a birthday card.（改为同义句）Lily give a birthday card to her friend.【分析】Lily给她的朋友一张贺卡。

【解答】考查同义句转换。

give sombody something＝give something to somebody给某人某物。

二者可以互相替换。

故答案为：give，to。

【点评】做题时，先要了解原句的意思。

可以用同义词，反义词等进行转换。

4．I'm from Russia. （改为同义句）I come from Russia.【分析】我来自俄国。

我来自俄国。

【解答】考查同义句转换。

I'm from Russia.表示出处，be from可以改为come from，主语为I，第一人称单数，谓语动词用原形。

故答案为：come from。

【点评】做题时，先要了解原句的意思，可以用同义词，反义词等进行转换。

5．I finished my homework yesterday. （变否定句）I didn't finish my homework yesterday.【分析】我昨天做完作业了。

2. 实义动词又分为可以后面直接跟宾语的及物动词和后面不需要跟宾语的不及物动词。

常用的助动词有：be, do, have, shall, will。

2. 助动词be（1）可用于构成时态，主要是进行时：I am looking at you.（2）可用于构成被动语态: You are being looked.（3）可与动词不定式构成谓语: My job is to look at you every minute.3. 助动词have(1) 构成完成时态：We have learned English for many years.(2)和动词不定式构成谓语，表示因客观环境促使不得不做的事情：We have to learn English very well.4. 助动词do(1) 构成疑问句和否定句：Dose he do his homework after school?(2)用来加强语气：I do want to buy a new car.(3)用来代替动词词组：Write a letter “L” as I do.5.助动词shall构成将来时态，单纯表示未来情况：Shall I begin?6.助动词will构成将来时，用于第一，二，三人称。

一、选择题1．Summer is coming. Please______ play near the river, It's very dangerous.A．can't B．no C．don't C解析：C【解析】【详解】句意：夏天要来了，请不要在河附近玩耍，它很危险。

考查祈使句的否定形式。

can't不可能；no不；don't不，根据祈使句否定形式的构成是：1、Don't+动词原形；2、No+动名词/名词，由所给空后面的play可知，应该用don't，故选C。

2．Mike, __________ make any noise, your father is sleeping.A．not B．don't C．won't D．can't B解析：B【解析】【详解】句意：麦克，不要吵闹，你父亲正在睡觉。

考查祈使句。

A. not 不，没有；B. don’t 不，没有；C. won’t 将不会；D. can’t 不能，不会。

A 选项为否定词；B选项为助动词，后面要接动词；C选项为助动词，将来时表将来；D选项为情态动词，表否定推测。

根据否定祈使句用法，应用助动词don’t + 动词原形结构。

A、C、D均不符合，故应选B。

3．---Be careful, don’t forget to follow your father.---I know that, Mum. One can never be too careful.A．and B．or C．but D．so A解析：A【解析】试题分析：and和，并且；or或者，否则；but但是；so因此。

句意：小心，并且不要忘了跟着你的父亲。

——我知道，妈妈。

一个人不可能永远太过小心。

故选A。

考点：连词辨析点评：连词在句子中主要起联系上下文的作用，他们之间的区别就是表示逻辑关系的不同，所以在解题时先要理解上下文含义，然后根据上下文逻辑关系选择合适的连词。
