为什么要被动?进行的时候,表示的是主动语态．如果是完成形式,有可能是做后置定语之类的,就没有BE动词．学英语不能太死．

现在进行时是由助动词to be 的现在时 + 现在分词构成：
肯定式 否定式 疑问式
I am working.You are working.He (she) is working.We (you,they) are working. I am not working.You are not working.He (she) is not working.We (you,they) are not working. Am I working?Are you working?Is he (she) working?Are we (you,they) working?
现在分词的构成,是在动词原形上加—ing, 但是应该注意：
情况 变化 例词
动词以单个e 结尾 去掉e, 加 ing Love _lovingArgue _ arguing
动词以 —ee结尾 直接加 ing Agree_ agreeingSee _ seeing
动词为单音节：以单一元音字母 + 单一辅音字母结尾 辅音字母双写,再加 ing Hit _ hittingRun _runningStop _ stopping
动词为双音节或者多音节：最后一个音节为重读音节,以单一元音字母 + 单一辅音字母结尾 辅音字母双写,再加 ing Be’gin be’ginningAd’mit ad’mitting
以 y 结尾的动词 直接加 ing Carry carryingEnjoy enjoying
现在进行时的功用
1） 表示说话时正在发生或者进行的动作
Please don’t make so much noise, I’m studying.
Let’s get out. It isn’t raining any more.
2) 表示在现在相对较长一段时间内正在进行的动作,但是说话一刻不一定在做的动作
Have you heard about Tom? He is building his own house.
David is teaching English and learning Chinese in Beijing.
这些动作,在说话时并不一定在发生或进行,而是在包括说话的一刹那在内的一段时间内发生、进行的.
3）表示最近的确定的安排
Ann is coming tomorrow.
Oh, is she? What time is she arriving?
At 10:15.
Are you meeting her at the station?
I can’t. I’m working tomorrow morning.
以上句子也可以用be going to (do) 的形式来表示.但是谈论已确定的安排时候,用现在进行时态显得更加自然,除非受到动词的功能的限制.在此,切不可用will, 如：
Alex is getting married next month. 不能用 will get married.
4) 和always 连用表示某种情绪,可能是厌烦也可能是赞扬,如：
Tom is always going away for weekends.
My husband is always doing homework.
有些动词是表示一种状态而不是动作,一般不用于进行时.例如,我们一般不说 I am knowing, 而说 I know. 常见的这类动词有：
want like hate know see hear believe understand seem
think(相信) suppose remember need love realize mean forget prefer have （拥有）belong
To understand is to accept. 理解就是接受
Do you like Beijing?
Do you see the rainbow?
I remember him very well.
I think I understand what he wants.
一般现在时和现在进行时的比较
一般现在时表示的是一般、重复的动作或者事情
现在进行时表示说话时或说话前后正在发生的动作或事情,如：
Tom plays tennis every Sunday.
Where’s Tom? -------He is playing tennis.
What do you do? 你是干什么工作的?
What are you doing here? 你在这里干什么?
一般现在时是表示经久的情况,而现在进行时表示的是暂时的,如：
My parents live in Shanghai. They have been there for 50 years.
She’s living with some friends until she can find an apartment.

⑴ 时间或地点介词in、on、at的用法区别：表示时间时, in表示在一段时间里(在将来时句子中则表示在一段时间之后), on表示在具体的某一天或者某天的上下午等, at表示在某个时刻或者瞬间；表示地点时, in表示在某个范围之内, on表示在某个平面上或与一个面相接触,at则表示在某个具体的场所或地点.如：He was born on the morning of May 10th.(他出生于五月十日的早晨)/ I usually get up at 7：00 in the morning.(我通常在早上的七点钟起床) / His glasses are right on his nose.(他的眼镜就架在他的鼻子上)/ He is at the cinema at the moment.(此刻他正在电影院)
⑵ after与in表示时间的用法区别：“after+(具体时刻/从句)”表示“在…时刻之后”常用于一般时态；“in+(一段时间)”表示“在(多久) 之后”,常用于将来时态.如：He said that he would be here after 6：00.(他说他六点钟之后会来这儿)/ My father is coming back from England in about a month.(我父亲大约一个月以后从英国回来)
⑶ since与for表示时间的用法区别：“since+(具体时刻/that-从句)”表示“自从…起一直到现在”,“for +(一段斶间)”表示“总共有…之久”,都常用于完成时态；如：Uncle Li has worked in this factory since 1970.(李叔叔自从1970年起就在这家工厂工作了)/ Uncle Li has worked in this factory for over 30 years. (李叔叔在这家工厂已经工作了30多年)
⑷ by、in与with表示方式的用法区别：都可以表示“工具、手段”,但是by主要表示“乘坐”某个交通工具或“以……方式”,在被动句中可以表示动作的执行者；in表示“使用”某种语言/文字,with表示“使用”某个具体的工具、手段.如：We see with our eyes and walk with our feet.(我们用眼睛看东西,用双脚走路)/ Please write that article(文章) in English.(请你用英语写那篇文章)/ Let’s go to the zoo by taxi.(我们打的去动物园吧.)/ It was written by Lao She.(那是老舍写的)
⑸ about与on的用法区别：都可以表示“有关…”,但是about的意义比较广,而on主要表示“有关…(专题/课程)”.如：Tom is going to give a talk on the history of America.(汤姆要作一个美国历史的报告)/ They are very excited talking about the coming field trip.(他们兴致勃勃地谈论着即将来到的野外旅游)
⑹ through与across、over的用法区别： through指“穿过…(门洞/人群/树林)”； across和over可以指“跨越…(街道/河流)”,可互换,但是表示“翻过…”时只能用over. 如：Just then a rat (鼠)ran across the road.(就在那时一只老鼠跑过路面)/ There is a bridge across/over the river.(河上有座桥)/ They climbed over the mountain and arrived there ahead of time.(他们翻过大山提前到达了那里)/ The visitors went through a big gate into another park.(参观者们穿过一个大门来到另一个公园)
(7)as与like的区别：两个词都表示“像……”,但是as译为“作为……”,表示的是职业、职务、作用等事实,而like译为“像……一样”,表示外表,不是事实.如：Let me speak to you as a father.(我以父亲的身份和你讲话.)(说话者是听者的父亲) / Let me speak to you like a father.(让我像一位父亲一样和你讲话)(说话者不是听者的父亲)
(8)at the end of、by the end of、to the end、in the end的用法区别：at the end of…既可以表示时间也可以表示地点,译为“在…末；在…尽头”,常与过去时连用；by the end of…只能表示时间,译为“在…前；到…为止”,常用于过去完成时； in the end与at last基本等义,表示“终于、最后”,通常用于过去时；to the end译为“到…的终点为止”,前面往往有表示运动或连续性的动词.如：By the end of last term we had learned 16 units of Book III.(到上学期期末我们已经学习了第三册16个单元)/ At the end of the road you can find a big white house with brown windows.(在路的尽头你能找到一幢有棕色窗户的白房子)/ They left for Beijing at the end of last week.(上周末他们动身去了北京)/ In the end he succeeded in the final exams.(他最终在期末考试中考及格了)/ We should go on with the work to the end.(我们应该把工作干到底)/ Follow this road to the end and you will see a post office.(沿这条路走到底就能看见一家邮电局)
(9)for a moment、for the moment、in a moment、at the moment的区别：for a moment“一会儿、片刻”(=for a while),常与持续性动词连用；for the moment“暂时、目前”,常用于现在时；in a moment“一会儿、立即、马上”(=soon; in a few minutes),一般用于将来时；at the moment“此刻,眼下”(=now),用于现在进行时.如：Please wait for a moment.(请稍等)/ Let’s leave things as they are for the moment.(暂时就维持现状吧!) / I’ll come back in a moment.(我过会儿回来)/ I am very busy at the moment.(眼下我很忙)
(10)but的问题：用介词but引出另一个动词时,要注意：如果前面有do,后面就用原形动词,前面没有do时,后面的动词要加to.如：I could do nothing but wait.(我什么也做不了只能等) / They had no choice(选择) but to fight.(他们没有选择只有战斗)
(11)in front of 与in the front of： in front of“在…的前面”, 与in the front of“在…的前部”.如：A car was parking in front of the hall.(大厅跟前停着一辆汽车)/ In the front of the hall stood a big desk.(大厅前部立着一个大讲台)
(12)except (for)与besides的区别：except“除了”,表示排除掉某人物,即不包含；而besides“除了”则表示包含,即“不仅……又……”.如：Everyone went to the Palace Museum except Tom.(除了Tom,大家都去了故宫博物院)(Tom没有去故宫)/ Besides Chinese he also studied many other subjects.(除了汉语之外,他还学其他许多功课)(“汉语”也是他学的功课之一)
other than 除了.之外. There 're nobody here other than me 与.不同. 与.不同方式.we can't get there other than by swimming.
Apart from : with the exception of ...; besides... Apart form a few scratches, the car was undamaged.

Students of Class 1 often have P.E lessons on the playground on Friday.They often jog together and have free exercises.They all have their favourite sports.William and some boys often play basketball,Tom plays football and Jack plays Ping-pong.Some girls play volleyball and some do aerobics,others like to take a walk.

先明白一下什么情况下用doing,done吧
过去进行时：was/were doing
现在进行时：is/am/are doing
现在完成时态：have/has done
过去完成时态：had done
这么看,是不是明白了? doing是现在分词,用于进行时态中,done是过去分词,用语完成时态中. 有问题请继续追问

1.He is watching movies/films.
2.I am swimming.
3.She is telephoning with/calling her mom.
4.His brother is walking.
5.I am having dinner.
6.We are singing.
7.He is playing piano.
8.He is reading a novel.
9.I am writing a letter.
10.He is running.

前几天有人问过这个问题,再paste一遍 :-)
1.如果动词以“e”结尾,只加“d”.
2.以“以辅音字母+y”结尾的动词,先将“y”改成“i”再加“ed”.
3.以重读闭音节结尾,而末尾只有一个辅音字母的动词,应将这个辅音字母双写,然后再加“ed”.
4.原形动词词尾为“元音+L,R”并为重读音节时,常双写 词尾后再加-ed
ed的读音规则：“清清浊浊”
在清辅音后读[t]；
在浊辅音后读[d]；
在[t][d]后读[id]
重读闭音节四个要素：
1.必须是重读音节；
2.音节以辅音结尾；
3.最后只有一个辅音字母；
4.元音字母发短元音；
重读闭音节就要双写.重读闭音节即两个辅音中间夹一个元音.
如:sit---sitting
begin---beginning(重读在gin这个音节上,相当与把gin该成双写的)
像travel这种重读不在的vel,可以为travelled,也可以是traveled.

感叹句的时态取决于原陈述句的时态.可以用进行式以及其他时态.

陈述句变感叹句全解
云在 2005.4.18
一、如何快速掌握感叹句?
学会分析五种基本句型的句子成分是快速掌握感叹句的关键,陈述句变感叹句实际上就是句子成分位置的移动.
例1 She is smiling sweetly.
→How sweetly she is smiling!（移动状语）
二、哪些句子成分可能会移动位置?
通过对句子成分的分析我们就可以确定哪个句子成分需要挪动位置,一般说来含有形容词的名词短语、形容词短语和副词短语需要变动位置.位置可能会变动的句子成分：宾语、表语和状语.
例2 Mr Turner told us a funny story.
→What a funny story Mr Turner told us!（移动宾语含有形容词的名词短语）
三、如何确定使用what还是使用how?
当我们做句型变换或选择题时需要自己确定到底是用what还是用how,一般可以这样来确定：位于主语之前的是名词短语时用what,是形容词或副词短语时用how.但这种格式例外: how + adj. + a/ an + N
例3 What a cool bike you are riding!（a cool bike 名词短语）
例 4 How fast he is riding!（fast 副词）
例 5 How cool a bike you are riding!（how + adj. + a/ an +N）
四、如何判断是否使用冠词、使用什么样的冠词?
名词的复数形式和不可数名词之前不使用冠词,以元音音素开头的词语之前用an,以辅音音素开头的词语之前用a.
例6 What beautiful sunshine it is today!（sunshine 不可数名词）
例7 What a useful book this is!（useful 以辅音音素开头）
例8 What an old house that is!（old 以元音音素开头）
五、感叹句有哪几种格式?
简单地说是"两型七式"：两种句型是以what开头的句型和以how开头的句型,七种格式是
① what + a + adj. + N+ S +V
② what + an + adj. +N +S +V
③ what + adj. + N（不可数） + S +V
④ what + adj. + N（可数名词复数形式）+ S+V
⑤ how + adj.+ S +V
⑥ how + adv. + S + V
⑦ how + adj. + a/ an + N + S+V
例 What exciting news it is!（what + adj. + N（可数名词复数形式）+ S + V结构）
例9 What good teachers they are!（what + adj. + N（可数名词复数形式）+ S+V结构）
例10 How warmly they are discussing!（how + adv. + S + V结构）
例11 How beautiful a picture it is!（how + adj. + a/ an + N + S + V 结构）
六、以what开头的句型和以how开头的句型怎样进行转换?
这两种句型之间的转换主要是指以下两种情况而言的:
⒈含有"a/ an + adj. + N "结构的句子方法是把形容词单独抽出来放在名词短语的前面和how搭配使用.
⒉名词短语作主语而表语是形容词的句子方法是把主语当作"a/ an + adj. + N"结构的中心名词而用人称代词充当主语.
例12 What an expensive glass he broke! →How expensive a glass he broke!
例13 How beautiful the birds are! →what beautiful birds they are!
（说明：N代表名词,未特别说明者代表可数名词的单数形式,S代表主语,V代表动词）
七、在感叹句中哪些词语常常省略?
常常省略的是充当主语的人称代词和动词be.
例14 What a naughty boy!（省略了he is）

你说的动词+ing（动名词）用在句子开头,是由动词构成动名词做主语的用法,另外动名词还可以在句子中做宾语、表语和定语,如下例子所示：
1）作主语.如：
Seeing is believing.
Laying eggs is the ant queen’s full-time job.
It is no use arguing with him.
2）作表语.如：
Her job is teaching.
3）作宾语.如：
He is fond of playing football.
I like swimming.
4）作定语,例如：
He has a reading room.
如有不明白可以继续问

不及物动词没有被动式,但是可以表示被动,wash ,sell ,dry 等和副词连用时,可用主动表被动
the book sells well.
不及物动词有进行式
the sun is rising.

现在进行时的基本用法：
a.表示现在( 指说话人说话时) 正在发生的事情.
We are waiting for you.
b.习惯进行：表示长期的或重复性的动作,说话时动作未必正在进行.
Mr.Green is writing another novel.
(说话时并未在写,只处于写作的状态.)
She is learning piano under Mr.Smith.
c.表示渐变的动词有：get,grow,become,turn,run,go,begin等.
The leaves are turning red.
It's getting warmer and warmer.
d.与always,constantly,forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩.
You are always changing your mind.
典型例题
My dictionary ___,I have looked for it everywhere but still___ it.
A.has lost,don't find B.is missing,don't find C.has lost,haven't found D.is missing,haven't found.
答案D.前句是一个仍在持续的状态,应用进行时,由于没有找到,其影响仍然存在,应用完成时,瞬间动词用于否定式时可用于完成时.
将来完成进行时的用法：
1）表示将来某时某事之前业已在发生的动作：
He will have been playing on the piano by that time．
2）表示将来某时某动作已持续多久：
By the time the sun rises,I shall have been sleeping fornine hours．
He will have been studying Chinese seven years by 1980．
By six this evening I shall have been working for ten hours.
It will have been raining for a whole week if it rains againtomorrow．
3）表示一种猜想,实际上指现在情况：
He will（=may）have been waiting for me．But I cannotgo,because it is raining．
It is winter．It will have been snowing in the north．
将来进行时的基本用法
表示在将来某一时间正在进行的动作.
I'll be taking my holiday soon.
我不久就去度假了.
在口语中代替will/shall do.
I hope you will be coming on time.
我希望你按时来.
2)将来进行时的特殊用法
表示原因、结果或猜测.
Please come tomorrow afternoon,Tomorrow morning I'll be having a meeting.
请你明天下午来吧.我明天上午有个会.(表原因)
You will be making a mistake.
你会出错的.(表推测)
3)用在问句中,表示委婉礼貌.
Will you be reading anything else?
你还要看点儿什么吗?
4)表示稍后一点儿的安排.
The students are studying Unit 3 this week,and next week they'll be studying Unit
这周学生们学第三单元,下周他们将学第四单元.

When+过去进行时,从句用一般过去时,这里的drop解释为突然扔下
如：When Iwas reading ,someone patted me on the shoulder.
当我在读书时,有个人突然拍了我的肩膀

能写的。本人英语是专业8级，如需要写这些，加一下i本人。

楼主的问题问得好啊,楼上不知道是不是点错网页了...
照我们英国老师的说法,这里用will be doing的时态和will do的意思基本没有区别,但是的确有语气上的细微差别,will be doing 有强调将来要做的这件事的意思在里面,所以你在读的时候要在be后面稍有停顿,而且这里和will do比较起来还有个在短时间内就会去做的概念,这里往往会加个时间状语以示这个动作很快就会去做,从句意来看就是我对产品质量不满,会尽快退回,而will do就没有一个时间的感觉在里面,这就是两者之间的差别,

动词原形变成现在进行式,结构为：am/is/are+动词的ing形式.am/is/are取决于主语的人称和数的变化（我用am,你用are,is就跟他她它,我们你们和他们一律全用are,are,are）,动词的ing形式,则遵循这样一个法则：
1.直接在动词末尾加上ing,如：doing,playing,seeing,working
2.不发音e结尾的,去e加上ing.
如：came-caming,make-making,dance-dancing等
3.以重读闭音节结尾,并且只有一个辅音字母的,双写辅音字母在加ing
如：begin-beginning,run-running,sit-sitting,shop-shopping等.
掌握了这些,你只要把书中的动词放到句子中进行变化就可以了,不用一一列举出来的.别着急慢慢理解语法规则,然后再到语句中进行运用、实践,自然就能掌握了.

是Stopping.
一般过去式双拼的判断方法和进行时一样的.
闭音节,重音,且发短音的单词,都是要双拼加ed或者ing的……
LZ还有什么问题可以单独消息我哟~

不定时：to do sth进行时：be+doing sth完成时：have been done

进行时在汉语中意为:正在进行的,在进行中的 　　在某些情况下会被网友用ING来表示 　　因为在英语中进行时是一种语法的语态,通常是在某动词后加ING来构成进行时态的词 　　所以会有用ING来代替进行时的用法 　　1现...

一般现在式：1、经常发生的动作,一般与every day ,often等表示经常性副词连用
如：I go to school every day.
2、客观存在的事实
如：The sun rises from the east.
3、现在发生的动作,一般与today,this year 等表示现在的时间连用.
如：I go to school today.
现在进行时：表示现在正在发生的动作：be(is,am,are)动词+doing ,一般与now等词连用.
如：She is drinking the green tea.
When the telephone rings ,I am washing the clothings.

选D 绝对正确 因为before i went to London 用的是过去式 所以 去伦敦之前在高中当老师这件事 是发生在过去的过去 并且持续了十年 所以要用过去完成进行时.
希望帮助成功,

楼主记错了,或者书上写错了.
1）must是情态动词后接动词原形,不可接不定式.
2）must have done 是must的虚拟语气,表示“过去一定做过某事” 是对过去的虚拟.
回答完毕!

这三类句型的改动都和助动词有关系.
常见的助动词有：BE,DO,MUST,WILL,CAN,其中有几个不是助动词,但因为用法差不多,所以归为一类.
如要进行改动,只需把助动词提出来,并进行相应改动即可.
例如：
一般现在 改 肯定 否定
一般过去 改 肯定 否定
现在进行式 改 肯定 否定
以上三者,将原句的助动词提出来,如改成否定形式的,将原句的助动词改成否定形式即可；如改成肯定形式的,将原句的助动词改成肯定形式.
一般问 改 特殊问句
应该是看划线部分是什么内容,比如时间,地点等等,并根据这个选择特殊疑问词.改成以下形式：
特殊疑问词+助动词+主语+动词+宾语

动词不变 仍用现在分词（动词+ing形式),只是在助动词(is are am)后面加上not就可以了.
例：
she is reading.:------she isn't reading.

将来时： I think I will be a reporter in ten years.I will in shanghai ,because I went to shanghai last year and fell in love with it.And I will live in an aparment with my best friends.I will have pets,b...

He has been to Beijing.（现在完成时.） I am watching TV .(现在进行时.） He often goes to school by bus.(一般现在时.） She will take a ride on the boat.(一般将来时.） We have been learning English for to years .（现在完成进行时） I was playing computer at 8 last night.(过去进行时.）

ought,will buy,is buying

一般现在时是to do
一般过去时是动词的过去式,一般是原词+ed结尾,不规则动词例外
一般将来时是 will或是现在分词（ing)表将来
现在进行时是系动词（am is are）+现在分词（ing）

死亡（die）是一个点动词,说白了,死亡是瞬间的,不是一个过程,不能说“某人正在死”啊.但是可以进行时表将来,dying.

你可不可以说个具体点的题目 …

过去进行时表示过去某个时间正在进行的动作.
I was watching TV at 9 o'clock last night.
现在完成时表示发生在过去的动作延续到现在或对现在造成影响.
I have lived here for ten years.(延续到现在)
I have cleaned my room.(对现在有影响:还很干净)

不一定要看情况.

修改完毕,注意第三人称单数

应该是have+动词过去分词吧：现在完成时
be+动词进行时：现在进行时

一般现在时,是 is are ,单数用 is ,复数用 are .
一般过去时,是 was were , 单数用 was ,复数用were.
一般将来时,是 going to ,或者 will ,
I'm going to piay football.我将要踢足球.
I'm going to.
I will``````

用had,因为他没强调正在这个动作

She WAS watching football while i WAS watching basketball
She WAS watching football while i went home
第2个表示的意思是,而.
她在看足球,而我却回家了
第一个是
在.的时候
她在看足球的时候,我在看篮球

单词以辅音字母,元音字母,辅音字母结束,且重音落在最后一个音节撒谎那个时,ing形式要双写最后一个辅音字母.

通常都是位移动词,如come,go ,leave,fly,arrive,move,start,begin,return等,这几个词是考试的时候经常出现的,其他的不怎么考到,平时注意积累

How to be a good learner?
As a good learner,we should form a good habit of learning,and study hard at our subjects in an efficient way.We'd get ready for each class and listen to the teachers carefully.After school,we'd better go over what we learned in class and finish our homework on time.We should study in groups so that we can help each other.We should work hard and do sports.What's your own opinion,can you tell me?
I hope all these will be helpful to us!

There is 不需要加进行时.如果你要用这个句式,可以说,
There is a talent show holding on the playground.
（有一个才艺展示正在操场上进行）
至于there is being我还没见过……

在与时间状语连用时,现在完成式与现在完成进行式两者含义相同.
例如:He has been writing a book for three years.
He has written a book for three yeas.这两个句子意思是一样的.
反之,如果只是He has been writing a book.则表示未完成还在进行.而He has written a book.就表示已经做完了.
现在完成时
（一）构成：have/has + 过去分词
（二）用法：
1.在未指明具体时间的情况下,现在完成时动词通常可以表示在说话之前已经完成,而后果或影响至今仍存在的动作.现在完成时把过去的动作和现在的结果联系起来.
It has taken effect since the first day of your employment.在你上班的第一天就开始实施.
2．现在完成时动词可以表示开始于过去持续到现在（也许还会继续进行下去）的动作或状态.例如：
I have studied English since 1975.我从一九七五年起就学习英语.
