反义疑问句can【篇一：反义疑问句can】1.can的反意疑问句一般要分两种情况来说.2.can如果是表示“能力/许可/请求”等时,则直接以can来变即可.如你的例子：he cant go to school today,can he?例句中的can表示的就是能力的含义.3.can如果表示可能性”,即翻译成“可能/不可能”,则与can无关,必须考查句子的具体时态和谓语动词形式,进行具体判断.如你的第2/3个例子,can就是表示可能性的含义.1）he cant work here now,does he?翻译：他现在不可能在这儿工作,是吗?方法：去掉can后,结合时间状语now,则句子正常写法为：he doesnt work here now,does he?2) he cant have done his work last night,did he?翻译：昨晚他不可能做过他的工作,是吗?方法：去掉can后,结合时间状语last night,则句子正常写法为：he didnt do his work last night,did he?4.如果上述情况中没有明确的时间状语,则根据句意可以加以适当变化.如：he cant have been to the usa before,has he?方法：去掉can,考虑到时间状语before,用现在完成时最好,即句子改成：he hasnt been to the usa before,has he?但是楼主给的第4个例句：he cant have done his work,did he?/has he?之所以是两种都可以,是因为去掉can后,没有具体明确的时间状语,所以句子可能变成：1）he didnt do his work,did he?也可能变成：2）he hasnt done his work,has he?【篇二：反义疑问句can】情态动词有哪些及用法情态动词 (model verbs) 又称为情态助动词 (model auxil-iaries), 主要有can, may, must, could, might, shall , should, will, would,ought to, need, dare等（过去式更委婉哦！）。
there be 句型意义There be 是英语中常用句型，意思是“有”，表示“人或事物的存在”。
There在此结构中是引导词，已经没有副词“那里”的含义。
There be 后面的名词是句子的主语，属倒装结构。
疑问句形式是将be或will/have/can/must等助动词、情态动词提至there之前，否定形式则直接在be或助动词、情态动词后加not，因此要表达“某个地方或某个时间存在什么事物或人”的时候常用“There be + 名词+ 地点（时间）这一句型。
结构1、There be 句型中的be 应和其后出现的主语在数上一致，即“近主原则”，如：There is a lamp on the table.There are some apples in the bowl.There are five books,two pens and a ruler in the school bag.There is a ruler,two pens and five books in the school bag.2、如果主语是复数名词，却表示一笔金额或一个总数或表达一个单个概念时，则仍用单数be形式，如：There is five hundred dollars to pay.There is still another 20 miles to drive.There is duck and green vegetables for supper.3、There be 中的be 有时可以是lie,stand,used to be,seem to be,appear to be 等，如：There lies a river to the south.There lived an old man in the small house.There stood a temple near the river.There used to be a castle at the foot of the hill.4、There is(was)+no +动词ing结构相当于It is(was) impossible to +动词原形，如：There is no going home. 回家是不可能了。
there be句型英语归纳1.three be句型的肯定句There be + 主语(某人/某物) + 某地（表示地点的介词短语）表示“某地有某人/某物”。
是一种存在关系，其主语是be动词后面的名词。
在There be句型的一般现在时态中，如果主语是可数名词单数和不可数名词，则be动词用is；如果主语是可数名词复数，则be动词用are，而在一般过去时态的句子中is/are要改为过去式was/were，即主语是可数名词单数和不可数名词用was，主语是可数名词复数用were。
表示地点的介词短语有in the room在房间里in the bottle在瓶子里on the desk在书桌上in the classroom在教室里等等。
There is a book on the desk. 书桌上有一本书。
（在there be句型中主语是be动词后面的名词，谓语动词be要和它后面的主语即名词保持一致，而这里的名词是book为可数名词单数，因此be用单数is）There is some water in the glass. 杯子里有一些水。
（在therebe句型中主语是be 动词后面的名词，而这里的名词water为不可数名词，因此be用单数is）There are some students under the tree. 树下有一些学生。
（在therebe句型中主语是be动词后面的名词，这里students为可数名词复数，因此be用复数are）There was a school in the village five years ago. 五年前这个村庄里有一所学校。
（这是there be 句型的一般过去时态，这里主语是可数名词单数school，所以be动词用单数was）2. there be句型的否定句：（有两种形式）（1）There be + not + 主语(某人/某物) + 某地表示“某地没有某人/某物”（否定句直接在be动词后加not，若句中有some要把some改为any，因为any常用于否定句和疑问句中表示“一些”）肯定句：There are some monkeys in the zoo.动物园里有一些猴子。

_________________________________________ __________.6.今天雨下得那么大，教室里可能没人。

_________________________________________ __________.8.曾经有一段时间我岁学习失去了兴趣。
There be 句型一肯定句：“There be+主语（某人/某物）+介词短语”，表示“（在）某地有某人/某物”。
这里的be的单复数形式要采取“就近一致”原则，即合靠近be的主语保持一致。
具体地说，there 后面第一个主语，若是单数时，be就用is/was;若是复数时be就用are/were。
如：There are three people in my family. 我家有三口人。
There is a pen and two books on the desk.书桌上有一支钢笔和两本书。
二．否定式：“There be +not+主语+介词短语”。
如：There isn’t a boy in the room.房间里没有一个男孩。
There aren’t any books on the desk.书桌上没有书。
注意：“There be句型”的否定式的构成和含有be动词的其他句型一样，在be后加not或no 即可。
注意not和no的不同：not是副词，no为形容词，所以not a/an/any+n.相当于no+n.。
例如：There are some pictures on the wall.There aren’t any pictures on the wall.=There are no pictures on the wall.There is a bike behind the tree.There isn’t a bike behind the tree.=There is no bike behind the tree.三．疑问式：Be there+主语+介词短语？”。
“No, there+be与not的缩写形式”。
如：—Is there a lamp 肯定回答是：“Yes, there be.”否定回答是：in your bedroom?在你的卧室里有台灯吗？—Yes, there is.是的，有。
there can be 是推断句，表示：可能有...There be表示存在的“有”，他有各种时态，如:一般现在时：there is/are；一般过去时：therewas/were一般将来时：there will be；过去将来时：there would be；现在完成时：there has/have been；过去完成时：there had been要特别注意be going to 在there be 句型中的运用。
例如：There is going to be a film in the meeting hall.学校礼堂里将有一场电影。
还可扩展为许多其它句型，下面笔者对There be句型的扩展作一归纳。
四，There be+名词+动词不定式这种句式中的及物动词(动词不定式)也可改成被动式, 意为"(没)有……要做"。
例如: There is a lot of work to do (to be done). 有许多工作要做。
There was no time to wait for you. 没有时间再等你了。
注意：There is nothing to do与There is nothing to be done. 含义不同。
前者意为:"无事可做",后者意为"没有办法"。
试比较:There is nothing to do-I'm bored.无事可做--我感到闷得慌。
(=There is nothing to entertain me.) 没有什么活动来消遣。
There is nothing to be done-we'll have to buy another one. 没有办法--我们只好另外买一个了。
(= There is no way off putting it right.)五There is+no+动名词这种句式可与"It is impossible+动词不定式"替换,意为"无法做某事"。
“there be 句型”详解There be句型是小学、初中英语学习中的重要内容，表示（某处）有（某物/人），基本结构为“There be +某物/人+某地”。
be动词的单复数必须依主语的变化而变化，单数is，复数are。
如：•There is a table in the room. 房间里有一张桌子。
•There are some birds in the tree. 树上有一些鸟。
一、句型结构1．There is+a/an+单数可数名词+地点状语There is a ruler on the desk.书桌上有一把尺。
2．There are+复数可数名词+地点状语There are four apples on the tree.树上有四个苹果。
There are some flowers in the park.公园里有一些花。
3．There is +不可数名词+地点状语•There is some water in the bottle. 瓶子里有一些水。
（水是不可数名词，即使有some, be动词也是单数。
）二、就近原则重要考点：There be句型中，几个名词并列时，be的单复数形式由最近名词单复数决定。
如：•There is a pen, two books and some pencils on the desk.本句中离be最近的是a pen, 因此be动词用单数is。
•There are two books, a pen and some pencils on the desk.本句中离be最近的是two books, 因此be用复数形式are。
•There is some bread and two bottles of apple juice on the table.本句中离be最近的是some bread, 因此be用单数形式。
•There are two bottles of apple juice and some bread on the table.本句中离be最近的是two bottles of apple juice, 因此be用复数形式。
therebe的句型结构
1. There be 句型啊，那可太常见了！就像“There is a book on the table”，你看，桌子上有本书，多简单明了呀！
2. There are so many stars in the sky. 哎呀，天空中那可是有好多星星呀，多美啊！
3. There was once a time when I had a great adventure. 曾经有那么一段时间，我可是有一场超级棒的冒险呢！
4. There will be a better future waiting for us. 肯定会有一个更美好的未来在等着我们呀，对吧？

我的观点结论就是：there be 句型真的超级实用又好用，在各种场景都能发挥大作用呢！。
