要做一名勤学生!2.行动动词开头.例如:Open the door! 打开门吧!Come here!到这儿来!否认形式的组成是一律在肯定形式的祈使句之前加上Don’t.例如:Don’t go there alone!不要一团体去那里.Don’t be late for class again!别再上课迟到.【问】在祈使句中加上please起什么作用?此时的否认句怎么变?【答】在祈使句中加上please可组成“Please…”或“…,please.”句式,please使句子语气显得更委婉、礼貌.此时的否认句应变成“Please don’t…”或“Don’t…,please”例如:Please give the book to me. / Give the book to me,please.请把那本书给我.Please don’t play with fire./ Don’t play with fire,please.请别玩火.【问】如何用let组成祈使句?其否认句式也是“Don’t let…”吗?【答】由let组成的肯定式的祈使句句型为:Let + 宾语 + 动词原形 + 其它.例如:Let me have a good rest.让我好好休息一下.以let引起的祈使句的否认形式,要视其在意思上否认了什么来决定.如否认let,则用Don’t let…向式;如否认let 前面的不定式,则在不定式前加not,即用“Let + 宾语 + not+ 动词原形 + 其它.”句式.例如:Don’t let the children play football on the road.不要让孩子们在马路上踢球.Let’s not wait outside to gate.咱们别在门外等.【问】什么时候you可以出现在祈使句中?【答】祈使句的主语通常不说出来,但有时为了指明向谁提出请求、命令等时,或为了增强语气,此时可说出主语you.例如:You feed the animals today.今天你喂动物.You sweep the floor. 你拖地板.【问】在肯定式的祈使句前加do起什么作用?【答】祈使句式的肯定式前加do可起强调作用.意为“务必;一定”等.例如:Do come,please!请一定来!Do tell her the thing.务必告知她此事.定义祈使句是英语的根本句型之一,表达说话人对对方的叮嘱、劝告、请求或命令等,往往有暗示请求、命令、希望、禁止、劝告等意思.祈使句一般没有主语,实际上是省略了主语“You”.句末用感慨号或句号,用降调朗读.肯定结构都以动词原形开头.例如:Catch the ball!接球!(句子的意思是让“你”接球)Go and ask the teacher.去问问老师.句子的意思是让“你”去问老师.Put the books in your bag.把书放到书包里.Come and meet my family.来看看我家人.二、句型1.祈使句的肯定句式有三种形式,即1)Do型(以行动动词原形开头),例如:Sit down坐下! Stand up起立!2)Be型(以be开头),例如:Be quiet宁静!3)Let型(以let开头),例如:Let me help you. 让我来帮忙你.注意:三种句型中Do型是最罕有、最复杂的一种结构.暗示请求、劝告的祈使句还经常在句前或句末加上Please, 组成句式:Please...或...Please.以使语气加倍和缓或客气.例如:Please stand up.或Stand up,please.请站起来.Please have a rest.或Have a rest,please.请休息一下. 2.祈使句的否认结构是以“Don't+动词原形”开头.例如:Don't go there,please.请别去那儿.Don't be late.不要迟到.Don't let him in.不要让他进来.Don't let the water run into the room.不要让水流进屋里. 注意:Let's型祈使句,其否认式也可用Let's not....如:Let's not have rest.咱们别休息了.Let's not sit here! 我们不要坐在这儿!。

2、以s,x,ch,sh或o结尾的动词,在后面加es,如:goes,teaches,washes等。

3、以辅音字母加y结尾的动词,把y变为i,再加es,如:study--studies,try--tries,carry--carries等。

4、动词have遇在主语是第三人称单数时,have改为has,如:He has an interesting book .5、动词be遇有主语是第一人称单数时,be改为am,遇有主语是第二人称时,be改为are,遇有主语是第三人称单数时,be改为is。

一、动词第三人称单数的变化规则及发音规律动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同,请认真观察。

1、大多数动词在词尾加“S”在清辅音后发音为[s],在浊辅音及元音后发音为 [z]。

在t 后读[ts],在d后读[dz],如:①stop-stops [s] ; make-makes [s]②read-reads [z] ; play-plays [z]2、以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”读[iz] 如:fly-flies [z]; carry-carries [z]study-studies [z]; worry-worries3、以“s, x, ch, sh”结尾的,在词尾加“es”,发音为[iz] 如:teach-teaches [iz]; watch-watches [iz]4、以“o”结尾的动词,加“es”,读[z] 如:go-goes [z] do-does [z]下面几个动词变为单数时,原词的元音部分的发音发生了较大的变化,请注意记忆。

动词变现在分词规则

动词变现在分词规则

动词变现在分词规则
一般来说,动词的现在分词形式是在动词原形(即动词的基本形式)
后面加上-ing。

但具体规则还有一些例外情况,以下是常见的动词变现在
分词的规则:
1. 一般情况下,在动词原形后加-ing:run → running(跑),
play → playing(玩),work → working(工作)。

2. 如果动词以一个辅音字母结尾,且前面只有一个元音字母,则双
写这个辅音字母,再加-ing:swim → swimming(游泳),sit →
sitting(坐),stop → stopping(停止)。

3. 如果动词以-e结尾(不包括-ee,如see),则去掉-e,再加-ing:take → taking(拿),drive → driving(开车),write → writing (写)。

4. 如果动词以-ie结尾,则将-ie改为-y,再加-ing:lie → lying (躺),die → dying(死),tie → tying(系)。

5. 以辅音字母+y结尾的动词,将-y变为-i,再加-ing:study → studying(学习),cry → crying(哭),r eply → replying(回复)。

6. 部分动词的变形不遵循以上规则,需要根据具体情况进行变化,
如go → going(去),do → doing(做),have → having(有)。

需要注意的是,在一些情况下,动词的变化可能取决于语境和词义,
所以在具体使用时还需根据上下文来确定正确的现在分词形式。
