Does this cloth wash well? 这布经得起洗吗?
实意动词的用法：
肯定句：
主语+动词过去式+其它
否定句：
主语+助动词didn‘t+动词原型+其他
一般过去式：
Did+主语+动词原型+其他
| 时态 | 主动形式 | 被动形式 |
| 一般式 | (not) to do | (not) to be done |
| 完成式 | (not) to have done | (not) to have been done |
| 进行式 | (not) to be doing | |
| 完成进行式 | (not) to have been doing |
现在分词构成形式：
①一般在动词原形末尾加ing，如do→doing、sing→singing、comfort→comforting
②以不发音的e、ue结尾的动词，先去e，再加ing，如dance→dancing、hike→hiking、write→writing、make→ making,take→taking
③以ee、oe、ye结尾的动词加ing，如see→seeing、toe→toeing、dye→dyeing
④以重读闭音节结尾的动词，并且末尾只有一个辅音字母，应双写这一字母，再加ing，如cut→cutting、swim→swimming

⑥以ic结尾的动词，要把ic变成ick再加ing，如picnic→picnicking，traffic→trafficking
过去分词构成形式：
1．规则动词：规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则：
(1)、一般动词，在词尾直接加“ ed ”。（然而要注意的是，过去分词并不是过去式）
work---worked---worked , visit---visited---visited
(2)、以不发音的“ e ” 结尾的动词，只在词尾加“ d ”。
live---lived---lived
(3)、以“辅音字母 + y ”结尾的动词，将 "y" 变为 "i" ，再加“ ed ”。
study---studied---studied,cry---cried---cried,try---tried---tried,fry---fried---fried.[1]
(4)、重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。
stop---stopped---stopped , drop---dropped--dropped
(5)、以ic结尾的动词，要把ic变成ick再加ed，
picnic→picnicked ，traffic→trafficked
2 、不规则动词：见不规则动词表
分词用法：
1、分词作状语
分词在句子中作状语，可以表示时间、条件、原因、结果、让步、伴随等。
分词（短语）作状语时，其逻辑主语应与句中主语相一致。
当现在分词表示的动作发 生在谓语动词之前时, 则用现在分词的完成式,且所表示动作与谓语动作同时发生, 则用现在分词的一般式。
完成或被动关系用过去分词。
①现在分词：
The students went out of the classroom, laughing and talking.
②过去分词：
Accompanied by his friend, he went to the railway station.
Given better attention, the plants could grow better.
2、“while ( when, once, until, if , though等连词)＋分词”结构
现在分词或过去分词作状语时，有时可以在分词前加while，when, once, although, until, if等连词。
①现在分词：
When leaving the airport, she waved again and again to us.
While waiting for the train, I had a long talk with my sister about her work……
②过去分词：
Once recovered, he threw himself into his work and made every effort to do it well.
Although working very hard, he failed to pass the final exam. If translated word by word, the passage will be difficult to understand.
3、分词作定语
分词作定语时，单个的分词通常放在被修饰的名词之前，分词短语一般置于所修饰的中心词后面。
现在分词修饰的是发出该动作的名词(即与名词有主谓关系)，过去分词修饰承受该动作的名词(即与名词是动宾关系)。
We will go on with our experiment as soon as we get the added fund.
This is really an exhausting day to all of us!
We can see the part of the moon lighted by sunlight.
After a night spent in excitement and sleeplessness, I forced myself to take a long walk along the beach the next day.
More and more developing countries established strategic partnership with developed countries
4、分词作宾语补足语
现在分词在see, watch, hear, observe, notice, feel, find, glimpse, glance等感官动词和look at, listen to等短语动词以及
have, keep, get, catch, leave, set, start, send等使役动词后面与名词或代词构成复合宾语，作宾语补语的成分。
例：I see him passing my house every day.
I caught him stealing things in that shop.
I smelt something burning.
5、分词作表语
分词作表语通常看作形容词来用。
过去分词表示主语的感受或状态，主语多为人。现在分词表示主语的性质，而且主语多为物；
①过去分词：
We were so bored that we couldn’t help yawning.
She felt confused, and even frightened.
②现在分词：
He was very amusing.
That book was rather boring.
很多动词的现在分词都可以作表语：
exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.

祈使句有三种类型：
一、含第二人称主语的祈使句
1. 当祈使的对象是第二人称you时称为含第二人称主语的祈使句。
这时，主语you通常不出现在句中，谓语动词用原形。
有时在句首或句末加please，还可加上称呼语，用逗号与句子主体隔开。如：
Please be quiet, boys! 孩子们，请安静！
Come this way, please. 请走这边。
如要加强语气，可在动词前加do。如：
Do keep away from the fire! 切记远离火种！
2. 否定式在谓语动词前加Don’t或Do not,强调否定式则在动词前加Never。如：
Don’t alway make the same mistake. 不要老犯同一个错误。
Never be late again. 千万别再迟到了。
3. 有时，为了强调指明向谁提出要求或发出命令，或表达说话人的急躁、厌烦、不满、恼怒的情绪，就用主语you表示，且放在动词前。如：
You come here! 你到这里来！
You mind your head! 小心别碰到头了！
若为否定式，则把Don’t放在主语you之前。如：
Don’t you come here! 你别来这里！
二、含第一、第三人称主语的祈使句
1. 含第一或第三人称主语的祈使句通常以Let开头，
第一人称由“Let + me / us +动词原形”构成，
第三人称由“Let + 第三人称代词（用宾格）或名词+动词原形”构成。
这类祈使句往往用于提出建议。如：
Let me have a try if you don’t want to. 如果你不想，就让我试一试吧。
Let’s spend this weekend in the country. 咱们到乡下去度这个周末吧。
Let him be here by ten o’clock. 叫他10点到这里吧。
有时也可以先称呼对方的名字，，后跟一句无人称主语的祈使句。如：
Jane, sit down please. 简，请坐下。
Mum, remember to bring me an umbrella. 妈妈，记得给我带把伞。
2. 这类祈使句的否定式是在动词原形前加not，也可以在let前加Don’t。如：
Let’s not wast our time about it. 我们不要为了这件事而浪费时间。
Don’t let us wait here. 别让我们在这儿等。
Don’t let him go out. 别让他出去。
三、无动词祈使句
在请求、命令和口号中，常用无动词祈使句，它实际上是省略了动词，从而使语句更简洁或有力。如：
Just a minute, please! 请稍等！
This way, please! 请这边走！
Attention! 立正！
Up the stairs! 上楼！
To the playground, everyone of you! 到操场上去，你们每个人都得去！
在一些指示牌上，常用“No +动名词/名词”构成简略式的否定祈使句。如：
No smoking! 禁止抽烟！
No parking! 禁止停车！
No photos! 禁止拍照！
还有一些是祝词类的无动词祈使句，如：
May you succeed！祝你成功！
Long live our friendship！我们的友谊万岁！
祈使句特点口令：
祈使句无主语, 主语you常省去;
动词原形谓语当, 句首加don't否定变;
朗读应当用降调, 句末常标感叹号。
祈使句的语调特点 ：
1、语音强度一般比陈述句重，书面上用叹号表示。
2、句末用降调，较长句子的后半部分几个音节速度加快。
对特定的人使用的祈使句：
祈使句如Wait here! (在这儿等着!) 可以是对一个人说，也可以是对几个人说，其主语暗含you。
但我们却可以用下列方式引起我们说话的对象的注意：
■You+祈使语气动词
You wait here for a moment. 你在这儿等一会儿。
语调和重音很重要。在上面这一句里，如果不重读you，那么句子的意思是this is where you wait (这就是你应等着的地方)；
如果重读you，那么句子的意思就是this is what I want you to do (这是我要你做的事)。
此外，重读you时还可以表示愤怒、敌意或不客气。如：
You mind your own business! 不关你什么事
You try teaching 40 noisy children five days a week! 你来试试每周5天教40个吵闹的孩子!
在否定句中Don’t要重读 (不重读you)。如：
Don’t you speak to me like that! 你别这样跟我讲话!
■“you+人名”或“人名+you”
You wait here, Jim, and Mary, you wait there. 你等在这儿，吉姆；玛丽，你等在那儿。
■“祈使语气+人名”或“人名+祈使语气”：
Drink up your milk, Sally! 把你的牛奶喝光，萨利!
Sally, drink up your milk! 萨利，把你的牛奶喝光!
■祈使语气+反身代词
Enjoy yourself. 你好好享受吧。
Behave yourself. 你放规矩点。
■对一群人讲话时，祈使语气可与everybody, someone之类的词连用：
Everyone keep quiet! 大家安静!
Keep still everybody! 每个人都保持不动!
Nobody say a word! 都不许说话!
Somebody answer the phone please. 请来个人接电话。
■在表示否定的命令语气后面可用带any的复合词
Don’t say a word anybody! 谁都不要说话!
Don’t anybody say a word! 任何人都不许说话!
直接引语和间接引语关系:
直接引语：直接引述别人的话（句子中有“”）。
间接引语：用自己的话转述别人的话，叫“间接引语”（句子中一般无“”）
间接引语在大多数情况下是一个宾语从语。直接引语变成间接引语时，要注意以下几点：
人称变化、时态变化、宾语从句要用陈述句语序。
1.直接引语是陈述句，变成间接引语时，由连词that 引导。例如：
She said, "I am very happy to help you."→She said that she was very happy to help you.
2. 直接引语是一般(选择/反意)疑问句，变成间接引语时，由连词whether或if 引导。例如：
He asked me, "Do you like playing football?"→He asked me if/whether I liked playing football.
注意：大多数情况下，if和whether 可以互换，但后有or not,或在动词不定式前，或放在介词后作连接词时，一般只用whether。例如：
She asked me whether he could do it or not.
He hesitated about whether to drive or take the train.
3. 直接引语是特殊疑问句，变成间接引语时，由相应的疑问词who, whom, whose, how, when, why, where 等引导。例如：
My sister asked me, "How do you like the film?"→My sister asked me how I liked the film.
4. 直接引语是祈使句，变成间接引语时，把动词原形变成动词不定式，并在动词不定前加tell, ask, order 等的宾语。例如：
The captain ordered, "Be quiet."→The captain ordered us to be quiet.
注意：此种情况的否定句，在动词不定式前加not。
My teacher asked me, "Don't laugh."→My teacher asked me not to laugh.
一些注意事项:
(1)如果直接引语是表示客观真理时，变为间接引语，一般现在时不改为一般过去时。如：
The teacher said "The earth goes round the sun."
→The teacher said that the earth goes round the sun.
(2)如果直接引语中有明确表示过时间的状语，变为间接引语时，一般过去时不改为过去完成时。如：
He said to me, "I was born in 1973."
→He told me that he was born in 1973.
(3)如果直接引语所述事实在当时和目前同样生效，变为间接宾语时，一般现在时不改为一般过去时。如：
He said, "I'm a boy, not a girl."
→He said that he is a boy ,not a girl.
(4)如果直接引语中的谓语动词表示一种反复出现或习惯动作，
在变为间接引时，一般现在时不改为一般过去时。如：
The girl said, "I get up at six every morning."
→The girl said that she gets up at six every morning.
(5)如果直接引语中含有since, when, while 引导的表示过去时间的状语从句，
在变为间接引语时，只改变主句中的谓语动词，从句的一般过去时则不变。如：
He said to me, "I have taught English since he came here ."
→He told me that he had taught English since he came here.
(6)如果直接引语中含有情态动词 must, need, had better以及情态动词的过去式could, might, should, would,
在变为间接引语时，这些情态动词没有时态的改变。例如：
The teacher said to me . "You must pay more attention to your pronunciation."
→The teacher told me that I must (have to ) pay more attention to my pronunciation.
He said , "I could swim when I was only six ."
→He said that he could swim when he was only six.
(7)间接引语一般要用陈述句的语序，即主、谓、宾的顺序。例如：
He asked Lucy, "Where did you go?"→He asked Lucy where she went.
Tom said, "What do you want, Ann?"→Tom asked Ann what she wanted.
宾语从句的特点:
1.宾语从句可以作及物动词、介词及形容词的宾语。
2.宾语从句的语序一律用陈述句语序。
3.连接词that引导宾语从句在句中无词义，不充当句子成份，多数情况下可以省略。
4.whether 和 if 都可引导宾语从句，但 whether后可紧跟or not；whether从句可作介词的宾语。
5.如果从句太长，可以用形式宾语it.
宾语从句的时态:
1.主句是一般现在时，从句根据实际情况使用任何时态。
例句：The headmaster hopes everything goes well.
2.主句是过去时态，从句须用过去时态的某种形式。
例句：She was sorry that she hadn’t finished her work on time.
3.当宾语从句表示的是一个客观真理或者事实时，即使主句是过去时，从句也用一般现在时态。
例句：The teacher told his class that light travels faster than sound.
4. 如果从句的动作发生在主句之前，则从句要用过去完成时态。
宾语从句的语序:
A. 宾语从句必须用陈述语序。
False: He is wondering when can he finish this difficult job.
Right: He is wondering when he can finish this difficult job.
B. 有时候可以用it 作形式宾语，而把真正的宾语从句放在后面。
Bad: I thought that he could finish this job in just two hours impossible.
Good: I thought it impossible that he could finish this job in just two hours.
C. 带有宾语从句的复合句的否定形式一般是否定主句。
Bad: I think he doesn’t like the English teacher.
Good: I don’t think he likes the English teacher.
D. 主句一般过去时态，从句也要用过去时态。
False: He wanted to know why he is crying in the corner.
Right: He wanted to know why he was crying in the corner
宾语从句的否定转移:
主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等。
并且主句的主语是第一人称而且为一般现在时，从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致。
I don’t think he will come to my party.而不能说成I think he won’t come to my party.
我认为他不会来我的舞会.
I don’t believe that man is killed by Jim,is he?
我认为那个人不是Jim所杀的,是不是?
如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式。
We find that he never listens to the teacher carefully,does he?
我们发现他从来不仔细听老师讲课，是不是?
宾语从句中引导词的用法比较
在复合句中作主句的宾语，引导词有：
连词：that (that 常可省略),whether, if
代词：who, whose, what ,which
副词：when ,where, how, why 等。
（一）that引导的宾语从句（在非正式场合that可以省略）
1.可跟that从句做宾语的动词有：
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句：The boy believes that he will travel through space to other planets.
注意事项：当主句谓语动词是 think, believe, suppose, expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。
例句：I don’t think it is right for him to treat you like that.
2.在以下情况中that不能省略
a.当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。
例句：He said (that) you were too young to understand the matter and that he was asked not to tell you.
b.当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。
例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
c.当that从句是双宾语中的直接宾语时，that不可省。
例句：I can’t tell him that his mother died.
d.注:许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。
例句：I find it necessary that we should do the homework on time.
（二）由whether,if 引导的宾语从句
1.由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。
一般说来，在宾语从句中whether与if可以互换使用，但在特殊情况下if与whether是不能互换的。
例句：I wonder whether(if) they will come to our party.
2.只能用whether，不能用if引导的宾语从句
a.在带to的不定式前
例句：We decided whether to walk there.
b.在介词的后面
例句：I’m thinking of whether we should go to see the film.
c.在动词后面的宾语从句时
例句：We discussed whether we had a sports meeting next week
d.直接与or not连用时
例句：I can’t say whether or not thet can come on time.
3.只能用if不能用whether引导的宾语从句
a.if引导条件状语从句，意为“如果”
例句：The students will go on a picnic if it is sunny.
b.if引导否定概念的宾语从句时
例句：He asked if I didn’t come to school yesterday.
c.引导状语从句even if（即使）和as if（好象）时
例句：He talks as if he has known all about it.
if,whether在宾语从句中的区别
a.if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if
b.少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.
c. whether后可以加or not,但是if不可以.
d.在不定式前只能用whether.
（如：I can’t decide whether to stay. 我不能决定是否留下。）
e.避免歧异时,我们常用whether而不用if.
（三）连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。
用于这种结构的动词常常是：see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
1.英语中的连接代词有：who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。
例句：Can you tell me whom you are waiting for?
2.英语中的连接副词有：when,where,why,how，在句中担任状语的成分。
例句：None of us knows where these new parts can be bought.
简化宾语从句常用六法：
方法一：
当主句谓语动词是hope， decide， wish， choose， agree， promise等，
且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式结构。
例如：
Li Ming hopes he will be back very soon.
→Li Ming hopes to be back very soon.
We decided that we would help him.
→We decided to help him.
方法二：当主句谓语动词是know， learn， remember， forget， tell等动词，
且主句主语与从句主语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：
She has forgotten how she can open the window.
→She has forgotten how to open the window.
注：当主句谓语动词是tell， ask， show， teach等动词，
且后带双宾语，从句主语和间接宾语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：
Could you tell me how I can get to the station？
→Could you tell me how to get to the station？
方法三：当主句的谓语动词是order（命令），require（需要）等时，
如果主句和从句的主语不一致，宾语从句可简化为“名词（代词）+不定式”结构。例如：
The headmaster ordered that we should start at once.
→ The headmaster ordered us to start at once.
方法四：某些动词后的宾语从句，可以用介词加动名词（短语）等其他形式简化。例如：
He insisted that he should go with us.
→He insisted on going with us.
The poor boy doesn’t know when and where he was born.
→The poor boy doesn’t know the time and the place of his birth.
方法五：某些动词后面的宾语从句可转化为“宾语+V-ing形式（作宾语补足语）”结构。例如：
Liu Ping found that there was a wallet lying on the ground.
→ Liu Ping found a wallet lying on the ground.
方法六：动词seem后的宾语从句，也可以用不定式（短语）来简化，但句型需要进行适当的变化。例如：
It seemed that the boys were going to win.
→The boys seemed to win.
除上述方法外，还有一些特殊句式的转化。例如：
I found that it was difficult to learn English well.
→I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow.
→Soon we found the ground covered with thick snow.
They found that the box was very heavy.
