助动词用法及练习使用不同类型的动词时,需要注意助动词的用法。
助动词主要用于帮助动词完成疑问和否定形式,本身没有实际含义。
常见的助动词包括be、do、will和have等,下面详细介绍它们的用法。
一、由连系动词am、is、are构成的句子:将am、is、are 提到句子前面即可变成一般疑问句,句尾加问号。
要否定句子,只需在am、is、are后面加not。
例如,He is a student。
变成一般疑问句为:Is he a student。
否定句为:He is not a student。
如果要提问主语或宾语,可以使用“Who”或“What”进行提问。
二、由情态动词can、may、will、shall等构成的句子:将情态动词提到句子前面即可变成一般疑问句,句尾加问号。
要否定句子,只需在情态动词后面加not。
例如,She can swim。
变成一般疑问句为:Can she swim。
否定句为:She can not swim。
如果要提问主语或宾语,可以使用“Who”或“What”进行提问。
对于过去式的情态动词,如could、might、would和should,变疑问句和否定句的方法与现在式相同。
三、由行为动词构成的句子:需要使用助词do或does。
将do/does放在句子前面即可变成一般疑问句,句尾加问号。
要否定句子,只需在动词前面加don’t/doesn’t。
需要注意动词的形式,一般疑问句和否定句的动词三单式都要变回原型。
例如,play变成do,plays变成does。
They play football after school。
He also plays XXX.Do they play football after school。
Does he play football after school?XXX.Who plays football after school。
What do they do after school。
千里之行,始于足下。

被协助的动词称作主要动词。
助动词自身没有词义,不可单独使用,例如:He doesn’t like english. 他不喜欢英语。
(doesn’t是助动词,无词义;like是主要动词,有词义)2、助动词协助主要动词完成以下功能,可以用来:a.表示时态例如:He is singing. 他在唱歌。
He has got married. 他已结婚b.表示语态例如:He was sent to england. 他被派住英国。
c.构成疑问句例如:Do you like college life? 你喜欢大学生活吗?Did you study english before you came here? 你来这儿之前学过英语吗?d.与否定副词not合用,构成否定句例如:I don’t like him 我不喜欢他。

He did know that. 他的确知道那件事。
3、最常用的助动词有:be, have, do, shall, will, should, would助动词本身没有词义,不能单独作为谓语。
它常配合主要动诩,协助构成否定句、疑问句,强调句、时态、语态等语法形式。
觉的助动词有:be, do, have(无词义)shall, will.一、be的助动词的用法be作为助动词,用来构成进行时态和被动语态。
如:We are working hard in the garden.(构成现在进行时)我们在花园里辛勤劳动。
The house was painted purple.(构成被动语态)房子被刷成紫色。
Be 作助动词用的常式如下:1、am, is, are, was, were2、助动词+be: shall be, will be, can be, etc.3、Have/has/had+been(完成时)4、Am, is,……being(进行时)(1)表达进行时态句型be+v-ing…(进行时态)例1:what are you reading?(你正在阅读什么?)I am reading a magazine.

Do do some work. 请一定做点什么;(4)代替前面刚出现的动词以避免重复。
不同时态助动词的用法在英语学习中,时态是一个重要的语法概念,而助动词在构成不同时态中起着关键作用。
理解和正确使用不同时态的助动词,对于准确表达时间和动作状态至关重要。
接下来,让我们一起深入探讨一下常见时态中助动词的用法。
一般现在时中,常用的助动词是“do/does”。
当主语是第三人称单数时,我们使用“does”,其余人称则用“do”。
例如,“I do my homework every day”(我每天做作业。
)“He does sports in the morning”(他早上做运动。
)这里的“do/does”主要用于构成疑问句和否定句。
比如,“Do you like apples?”(你喜欢苹果吗?)“She doesn't go to school on Sundays”(她周日不上学。
)一般过去时的助动词是“did”。
无论主语的人称和单复数如何,都用“did”。
它同样用于构成疑问句和否定句。
像“Did you see the movie last night?”(昨晚你看那部电影了吗?)“They didn't come to the party”(他们没来参加聚会。
)在肯定句中,我们不需要助动词,直接用动词的过去式,例如,“I went to Beijing last year”(我去年去了北京。
)现在进行时的助动词是“be(am/is/are)”。
“am”用于第一人称单数“ I ”,“is”用于第三人称单数,“are”用于第二人称以及第一、三人称复数。
比如,“I am reading a book now”(我现在正在读书。
)“He is playing football”(他正在踢足球。
)“They are having lunch”(他们正在吃午饭。
)需要注意的是,现在进行时表示正在进行的动作。
过去进行时的助动词是“be(was/were)”。
“was”用于第一人称单数和第三人称单数,“were”用于第二人称以及第一、三人称复数。
小升初:一般现在时助动词用法及练习助动词又叫协助动词,起协助/辅助作用,不能单独作谓语,只有与实义动词一起才可以用作谓语。
可以用来表示否定,疑问,时态,语态和语气等。
常见的助动词有do/does/did/am/is/are/have/ has/will/shall/would等。
小学阶段常考的是一般现在时和一般过去时相关的do/does/did.(用来构成提问)句型结构:否定句:主语+don’t/doesn’t/didn’t +动词原形+其他一般疑问句:Do/Does/Did +主语+动词原形+其他?肯定回答:Yes, 主语+do/does/did.否定回答:No,主语+don't/doesn’t/didn’t.【课堂巩固】一.用do和does填空。

be动词,情态动词,助动词do/does的用法区别及练习助动词,顾名思义就是帮助动词完成疑问及否定的,本身没有什么含义。
主要的助动词有be,do,will,have 等,其用法详述如下:—、(D由连系动词am, is, are构成的句子:变一般疑问句时把am, is, are提到句子的前面,句尾用问号即可。
变否定句时直接在am, is, are后面加not即可。
例如:肯定句:He is a student.—般疑问句:Is he a student?否定句:He is not a student.画线提问:对he提问:Who is a student?对 a student 提问:What is he?(2) was是am,is的过去式,were是are的过去式,若句子中有以上两词时,变疑问句及否定句方法与(1)相同。
二、(1)由情态动词can, may,will , shall等构成的句子:变一般疑问句时把can, may,will ,shall提到句子的前面,句尾用问号即可.变否定句时直接在can,may后面加not即可.例如:肯定句:She can swim.—般疑问句:Can she swim?否定句:She can not swim.画线提问:对she提问:Who can swim?对swim 提问:What can she do?(2) could,might,would,should是can,may,will,shall的过去式,若句子中有以上两词时,变疑问句及否定句方法与(1)相同。

Does he play football after school?否定句:They don't (do not) play football after school. He doesn ' t' play football after school. 画线提问:对they/he 提问:Who plays football after school?对play football 提问:What do they do after school?
