动词过去式变化规则及其读音规则
规则动词的过去式变化如下：
1、一般情况下，动词词尾加-ed ，如：
work ---worked play---play ed wanted----wanted act----acted
2、以不发音的-e 结尾动词，动词词尾加-d，如：
liv e---liv ed mov e----mov ed taste---tasted hope---hoped
3、以辅音字母+ y结尾的动词，把-y变为-i 再加-ed，如：
study---studied copy---copied cry---cried carry---carried
4、以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加-ed，如：stop ---stopped
5、不规则动词的过去式变化规律性不强，须多加记忆。
go – went make – made get – got buy - bought come - came f ly-flew
不规则动词的过去式的构成
1．把动词原形中的i改为a，变成过去式。如：
begin—began，drink—drank，giv e—gav e，ring—rang，sing—sang，sit—sat，swim—swam 2．把重读开音节中的i改为o，变成过去式。如：
driv e—drov e，ride—rode，write—wrote

过去式
是英语语法的一种，表示过去某个时间里发生的动作或状态。一般过去式的动词通常用动词的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。
目录
过去式，过去时态
【过去式】
1、过去发生的而现在已经结束的动作要用一般过去式来表示。
2、表示过去某个时间里发生的动作或状态。
3、过去习惯性、经常性的动作、行为；过去主语所具备的能力和性格。
【过去时态】表示行为、动作和状态在各种时间条件下的动词形式。
【过去时态结构】指的是过去时态下的动词形式的语法构成。
过去式就是动词的变化，表示过去发生的事。一般看到ago,before, in 几几年，就是过去式。
work-worked
listen-listened 一般的就是直接加ed，特殊的就有一些变化。
结构
【过去时态结构基本形式】
1、主语+动词过去式+其他；
2、否定形式
①wasn't/weren't
②在行为动词前加didn't，同时还原行为动词；一般疑问句Did+主语
+do+其他。
概念：
表示过去的发生动作或过去存在的某种状态
例句：
A:What did you do last weekend?
B:I played football.
A:Did you read books?
B:Yes,I did.
构成
表示一般过去式的动词通常用动词的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。规则动词的过去式变化如下：
（1）一般情况下，动词词尾加 ed ，如：
work—worked； play—played；want— wanted； act—acted
（2）以不发音的 e 结尾动词，动词词尾加 d，如：
live—lived； move—moved； decide—decided； decline—declined；hope—hoped；
（3）以辅音字母 + y结尾的动词，把y变为i 再加ed，如：
studied tried copied justified cried carried embodied emptied
（4）以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加 ed，如：
stopped begged fretted dragged dropped planned dotted dripped （5）注：不规则动词的过去式变化规律性不强，须多加记忆。
go - went，make - made，get - got ，buy - bought ，come - came ，fly-flew ，is/am-was，are-were ，see-saw，bring-brought，do-did，teach-taught, think-thought, say-said,sit-sat. read-read,
spend-spent,
eat-ate,give-gave,sit-sat,tell-told,write-wrote,feel-felt,find-fo und,hear-heard,know-knew,
put-put,grow-grew,take-took,catch-caught,come-came,become-became, swim-swam，sweep—swept，sing—sang，draw—drew，
以上的（1）至（4）条中的发音均有改变，具体分别有/d/ /t/ /id/。
而不规则动词的过去式的发音则略有不同，但是有些还是按照一定规律变化的。如以上的：make - made，get - got ，buy - bought ，come - came ，fly-flew ，bring-brought，teach-taught, think-thought,
say-said,sit-sat. read-read,
spend-spent,give-gave,tell-told,write-wrote,feel-felt,find-found, hear-heard,know-knew,put-put,grow-grew,take-took,catch-caught,com
e-came,become-became,swim-swam，sweep—swept，sing—sang，draw—drew。
仔细看一看，能发现它们的一些变化规律，也就是说不需要死记硬背这些过去式，知道了原型和变化规律，就可以写出来了。有的变化部分读音也是有规律的。分类记忆是对学习过去式很有帮助的！
用法：
（1）
表示过去某一时刻或某一段时间内所发生的动作或情况，通常一般过去式带有表示动作时间状语的词，词组或从句,如 yesterday, the day before last, last week, two days ago 等,上下文清楚时可以不带时间状语。 I worked in that factory last year. 去年我在那一家工厂工作。 I went to the Tian Long Mountain yesterday. 昨天我们去了天龙山。
一般过去时的用法一.概念：一般过去时是表示在过去的时间里发生的动作或状态，通常与表示过去的时间状语连用。
二．时间状语：yesterday, the day before yesterday, two days ago, long long ago,a minute ago,last year(week, month), just now, at that time, in those days.
三．过去时的用法：1．有确定的过去时间状语时要用过去式。
例：We had a good time last week.
2．表示过去连续发生的动作时，要用过去式。
例：The boy closed the door, turned off the window, and then went to bed.
3. 表示过去一段时间内经常或反复的动作，要用过去式。
例：She often came to help me at that time.
四.一般过去式的构成形式：☆Be动词的过去式： (1)肯定句：主语+ be
动词的过去式（was, were）
例：He was ill yesterday. She was nine two years ago.They were my students long long ago.
(2)否定句：主语+ be动词的过去式（was, were）+ not
例：He was not ill yesterday.She was not nine two years ago.They were not my students long long ago.
(3)一般疑问句：直接把be动词提到句首。
例：Was he ill yesterday?
肯定回答：Yes, he was.
否定回答：No, he wasn't.Was she nine two years ago? Yes, she was. / No, she wasn't.Were they your students long long ago? Yes, they were. / No, they weren't.
☆实意动词的过去式：(1)肯定句：主语+动词的过去式
例：He played football last week.She watched TV last night.
(2)否定句：主语+ did not +动词原形
例：He did not play football last week.She didn’t watch TV last night.
(3)一般疑问句：Did +主语+动词原形例：Did he play football last week?
回答：Yes, he did./ No, he didn't.
Did she watch TV last night?
回答：Yes, she did. / No, she didn’t.
五．动词变过去式的几种常用规则：1．一般动词直接+ ed;
例：look--looked want--wanted listen --listened
2．以e结尾的词直接+ d;例：live--lived phone--phoned
3．以辅音字母加y结尾, 变y为i加ed;例：try--tried study--studied 4．重读闭音节结尾的，词尾只有一个辅音字母，双写词尾辅音字母+ ed;例：stop--stopped plan--planned
5.不规则动词: 动词由原形转变为过去式时不按词尾加“-ed”之变化
规则者叫做不规则动词。小学常见的动词不规则过去式如：是be/is/am/are- was, 是are- were, 来come-came, 去go- went, 有have- had, 做/干do- did, 做make- made 读read- read, 放put- put, 切割cut- cut,写write- wrote, 带走take- took, 买buy- bought, 带来bring- brought,想think- thought, 看见see- saw, 说say- said, 说话speak- spoke,打破break- broke, 得到get- got, 跑run- ran, 告诉tell- told,唱sing- sang, 喝drink- drank, 吃eat- ate, 游泳swim- swam,开始begin- began, 偷
steal- stole, 遇见meet- met, 卖sell- sold, 坐sit- sat,跑run-ran,
读read-read,想要want-want,知道know/known等等
表示过去某一时刻或某一段时间内所发生的动作或情况，通常一般过去式带有表示动作时间状语的词，词组或从句,如 yesterday, the day before last, last week, two days ago 等,上下文清楚时可以不带时间状语。 I
worked in that factory last year. 去年我在那一家工厂工作。 I went to the Tian Long Mountain yesterday. 昨天我们去了天龙山。I stayed at home,yesterday.昨天，我整日呆在家里.
（2）
一般过去时态：表示过去某一时间所发生的动作或存在的状态。谓语动词要用一般过去式。
时间标志：yesterday（昨天）, last weekend（上周）, last month （上个月）, last year（去年）, two months ago（两个月前）, the day before yesterday（前天），in 1990 (在1990年), in those days （在
那些日子里）等表示过去的时间状语。
如：
I was born in 1990. (我出生在1990年)。
When did you go to the park? （你是什么时候去的公园）。
I went to the park last weekend. （我是上周去的公园）
在上面的句子中第一句属于be动词的一般过去时态；
第二句和第三句属于实义动词go的一般过去时态。
1． Be 动词的一般过去时态
在没有实义动词的句子中使用be动词， am is 的过去式为was; are
的过去式为were.
构成：
肯定句：主语+was (were) +表语
如：I was late yesterday. （昨天我迟到了。）
否定句：主语+was (were) +not+表语
如：We weren't late yesterday. (我们昨天没迟到)
疑问句：Was (Were) +主语+表语
如： Do you sick yesterday? （你昨天病了吗？）
肯定回答： Yes, I was. (是的，我病了。)
否定回答： No, I wasn't. (不，我没病。)
特殊疑问句：特殊疑问词+was (were) +主语+表语
如：When were you born? 你是什么时候出生的？
读法：
规则动词词尾加-ed有三种读音：
1. 在清辅音后读作[t]。如：asked, helped, watched, stopped
2. 在浊辅音和元音后读作[d]。如：enjoyed, studied, moved, called
3.在t / d后读作[id]。如：wanted, needed
不规则动词的过去式大体上归纳有以下六条记忆法：
1. 以t结尾的词，过去式与原形相同。如：put—put, let—let, cut—cut, beat—beat
现在分词加ing的规则
现在分词加ing的规则
现在分词是在动词后加上ing 构成。如:starting,working, coming, sitting 等都是现在分词。现在分词的变化规则是固定的，大家用心记一下就可以了。
(1)直接在谓语动词后加ing. 例如：going, starting, working.
(2)去掉词尾不发音的e，再加ing. 例如leaving,dining.
注意：如果单词结尾的e发音，则不能去掉，也直接加ing. 例如：see -seeing/agree - agreeing .
另外，有少数动词比较特殊，请用心记住：例如：lie - lying/die - dying/tie - tying/picnic - picnicking.
(3) 对于重读闭音节词，双写末尾字母再加ing. 例如：sitting, beginning.
这一条规律，必须要弄清什么是“重读闭音节”。下面再举一些双写的例子：
run - running
stop - stopping
cut - cutting
control - controlling
动词不定式、动名词用法要点讲解详细内容
⒈不定式作主语
动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种：
(1)把不定式置于句首。如：
To get there by bike will take us half an hour.
(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如：
①It＋be＋名词＋to do
It's our duty to take good care of the old.
②It takes sb+some time+to do
How long did it take you to finish the work?
③It＋be＋形容词＋for sb＋to do
It is difficult for us to finish writing the compositionin a quarter of an hour.
④It＋be＋形容词＋of sb＋to do
It is stupid of you to write down everything the teachersays.
⑤It seems(appears)＋形容词＋to do
It seemed impossible to save money.
在句型③中，常用表示客观情况的形容词，如：difficult,easy,hard,important,impossible,necessary 等；在句型④中，常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise等表示赞扬或批评的词。在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is＋形容词＋to do句式，如：It'skind of you to help me with my English.=Y ou are kind to helpme with my English.
⒉动名词作主语
Learning without practice is no good.
动名词作主语时，也常用It句式。如：
①It's +no good(no use,fun,a pleasure,a waste of time)+doing…
It's no good reading in dim light.
It's no use sitting here waiting.
②It's＋形容词＋doing
It's dangerous swimming in the sea in windy days.
这样用的形容词有expensive,nice,tiring等，但important,necessary则不适用于这种结构，应用不定式代替，如：It'simportant for you to keep fit.
③There is no+doing
There is no saying what will happen next.
在这一结构中，动名词后常带宾语，相当于"It's impossible to…"结构。
⒊动词不定式和动名词作主语的区别
①不定式作主语经常表示具体动作，常与特定的动作执行者联系在一起；而动名词作主语经常表示抽象动作，经常不与特定的动作执行者联系在一起。如：
It's no good eating too much fat.
It's no good for you to eat so much fat.
②动名词结构作主语，可以用名词或代词属格形式作逻辑主语。如：
It's no use your pretending that you didn't know the rules.
二、作宾语
⒈不定式作宾语
①以下动词后，只能跟不定式作宾语。如：agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,long,
manage,offer,plan,prepare,pretend,promise,refuse,wish等，这些词大部分可接th at引导的从句。如：
I decided to ask for my money back.
I decided that I would ask for my money back.
When our visit to the farm was over,we expected to startback on foot.
When our visit to the farm was over, we expected that wewould start back on foot.
②当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，即：主语＋动词＋it＋补语＋to do句式。如：
We think it quite important for us to learn a foreignlanguage well.
He feels it his duty to help the poor.
③介词but,except,besides+to do(do)
在这种句型中，如介词前有动词do，后面应接不带to的不定式；如无do，则接to不定式，即带do不带to，带to不带do。如：
The enemy soldiers had no choice but to give in.
On Sunday afternoon I had nothing to do but watch TV.
⒉动名词作宾语
①以下动词后，只能接动名词作宾语，如：admit,appreciate,consider,delay,enjoy,finish,keep,imag ine,mind,miss,practise,resist,risk,save,suggest,don't mind,give up,insist,on, put off等。如：
I suggest spending our summer vacation in a seaside town.
Y ou must give up smoking, for it does too much harm toyour health.
②动名词作介词的宾语
I should go to attend the birthday celebration instead of staying at home.
What about inviting Li Jun to make a speech?
动名词前的介词有时可以省略，如：have difficulty(in)doing,have no trouble(in)doing,lose no ti me(in)doing,prevent/stop…(from)doing,there is no use(in)doing等。
⒊部分动词后面，既可接动词不定式，也可接动名词作宾语，意义不变。如：begin,continue,start,hat e,like,love,need,require,want等。
在need,require,want后接-ing形式，表示被动意义，也可接不定式，但要用被动形式，如：Y our handwr iting needs improving(tobe improved). hate,love,like接不定式表示特定的未来事件，接动名词表示目前正在进行的活动或一般的行为。
在下列情况下，一般要用不定式：
①hate,like,love前有would(should)时，如：I'd like to have a cup of coffee.
②当谓语动词begin,continue,start等是进行式时，如：Thestudents are starting to work on the di fficult maths problem.
③begin,continue,start与know,understand等状态动词连用时，如：I soon began to understand what
was happening.
⒋advise,allow,encourage,forbid,permit等动词后接动名词作宾语，或带不定式作宾语补足语。如：
Our teachers don't permit our swimming in the lake.
Our teachers don't permit us to swim in the lake.
⒌部分动词后接不定式或动名词时，意义差别较大，应根据句子语境选择使用。
①forget,remember,regret后接不定式，表示现在或未来的动作，接动名词表示动作已经发生。如：
Don't forget fo post the letter for me.
Have you forgotten meeting her in Beijing Airport?
Remember to close the windows before you leave.
I remember writing him a letter a year ago.
We regret to tell you that all of you are not invited toattend the meeting.
They regretted ordering these books from abroad.
②mean to do 打算做某事
doing 意味着……
I meant to catch up with the early bus.
This means wasting a lot of money.
③try to do 设法尽力做某事
doing 试着做某事
Y ou should try to overcome your shortcomings.
Try working out the physics problem in another way.
④stop to do 停下一件事去做另一件事（不定式作目的状语）
doing 停止做某事
On the way to the airport,I stopped to buy a paper.
Y ou'd better stop arguing and do as you are told.
⑤can't help doing 禁不住……
to do不能帮助干……
They couldn't help jumping up at the news.
Sorry I have lots of work to do.So I can't help to make up the room for you.
⑥go on to do 做不同的事或不同内容的事
doing 继续不停地做某事，指同一动作的继续
He went on to talk about world situation.他接着又谈了世界形势。
We'll go on fighting so long as there is oppression inthe world.
⑦leave off to do 离开某地去干什么（目的状语）
doing停下某事
It's time to leave off talking and to start acting.
They left off to go fishing.
三、做表语
不定式作表语表示具体动作或将来动作；动名词作表语表示抽象的一般行为。
①To be kind to the enemy is to be cruel to the people.
②My chief purpose is to point out the difficulties ofthe matter.
③What I would suggest is to put off the meeting.
当主语和表语都是不定式时，其含义一是条件，一是结果（例①）。当主语是aim,duty,hope,idea,mista ke,plan,purpose,suggestion等为中心词的名词词组（例②）时，或以what引导的名词性分句（例③），不定式说明主语的内容。
④Our work is serving the people.
⑤What he likes is taking a walk after supper.
⑥The story told by Mr.Wang is interesting.
④⑤句动名词作表语，与主语部分可以转换，如Serving thepeople is out work,而⑥句中是现在分词作表语，说明主语的性质、状态，现在分词具有形容词的各种特征，另外，动名词作表语还应与进行时态区别开来。
四、作定语
⒈不定式作定语
不定式在句中作定语，置于被修饰的名词或代词之后。如：
①The next train to arrive is from Washington.
②Have you anything to be taken to your sister?
③Do you have anything to say on the question?
④Would you please give me some paper to write on?
⑤My wish to visit France has come true at last.
不定式短语作定语和被修饰词之间表示以下关系：
(1)表示将来的动作（例①）。
(2)与被修饰词之间有动宾关系，如是不及物动词，则需加介词（例④）。
(3)与被修饰词之间有动宾关系，同时与句中其它词之间又有逻辑上的主谓关系时，尽管有被动含义，却仍用主动语态（例③）；如只有动宾关系，而无逻辑上的主谓关系，则需用被动语态（例②）。
(4)不定式作定语时，一般可转换为定语从句，例①to arrive=that will arrive。
⒉动名词作定语
①This passage can be used as listening materials.
②The reading room of our school library can hold 800people.
③All moving bodies have energy.
①②句动名词作定语说明一种性能，即：用来……的；第③句为现在分词作定语，单个分词作定语常置于被修饰词之前，与被修饰词之间，可构成逻辑上的主谓关系，分词短语作定语常置于被修饰词之后。如：The man standing at the school gate is Professor Hua.
五、不定式作补足语
⒈作宾语补足语
一些及物动词除要求按宾语外，有时还需要有宾语补足语，说明宾语的行为、状态、特征，这时意思才相对完整。
(1)常要求不定式作宾补的动词有：allow,ask,advise,beg,cause,drive（强迫），encourage,expect,fo rbid,force,get,would like(love,hate),order,permit,persuade,teach,tell,want,warn,wish等。如：
①Would you like me to give your regards to Mary?
②I want you to understand the whole passage clearly.
(2)部分动词后常接to be＋形容词、名词短语等形式，有时to be可省略，如：believe,consider,discov er,find(=consider),feel(=think),imagine,judge,know,prove,think,suppose,see(=understand),understa nd等。
①We all believe John(to be)honest.
②I consider him(to be)one of the best biology teachers of No. 1 Middle School.
但当不定式是完成式时，to不能省略，如：We consider him tohave been foolish.
(3)感觉动词和使役动词后用作宾补的不定式须省略to。
①I didn't hear anyone say anything about it.
②They make the students do too much homework every day.
这种句式在变为被动语态时，to不能省略，如第②句：Thestudents are made to do too much homework every day.
(4)help,know后面的"to"可有可无。如：
Would you please help me(to) fill in the taxform?
I've never known her(to)be late before.但：He was known to have been to France before.
(5)部分短语动词后，常接不定式作宾补，如：
Y ou may depend on them to be there early.
The Party calls on us to increase production and practise economy.
常这样用的短语动词有：ask for,care for,call on,count on,depend on,wait for,long for（渴望），prepare for,wish for等。
⒉作主语补足语
不定式作主语补足语，和主语构成一种逻辑上的主谓关系。如：
①He was not allowed to enter the classroom for being late.
②The young university student is considered to have great promise.
六、不定式作状语
⒈作目的状语
(1) ①I stayed there to see what would happen.
②Henry has decided to go to the hospital to be examinedby the doctor.
(2)有时为了强调，不定式前可加in order或so as。如：
Bob took down my telephone number so as(in order)not toforget it.
有时为强调目的状语可把in order to或不定式置于句首，但so as to不能这样用。在这种句式中不定式部分可转换为so that,in order that,成为目的状语从句，如：
I stayed there so that (in order that)I could see whatwould happen.
(3)在部分表示感情色彩的形容词、过去分词或动词之后可接不定式，如：astonished,glad,happy,laugh ,pleased, sad,smile,sorry,surprised等。
①We are glad to hear the news.
②I was surprised to see that a three-year-old baby could write so well.
在部分形容词后接不定式，用主动形式表示被动意义，这种句型中的主语是不定式的逻辑宾语。如：The question raised by thestudent is difficult to answer.
The room is really comfortable to live in.
常这样用的形容词有：comfortable,easy,dangerous,difficult,expensive,fit,impossible等。
⒉作结果状语
We came home after our holiday to find our garden neat and tidy.
不定式作结果状语还常用在下列句式中。如：
①so…as to;such…as to
I'm not so stupid(a fool) as to put it in writing.我不至于愚蠢到会把它写下来。
I'm not such a stupid fool as to put it in writing.
②enough…to
The speed is high enough for us to catch up with thefirst liner.
③only to
Jane hurried back only to find her mother dying inthehospital.
④t oo…to
I'm too tired to stay up longer.
但在下列结构中，too…to并非是“太……而不能……”之意。如：
①I'm only too glad to have passed the exam.考试及格我太高兴了。（too修饰glad to have…，相当于very）
②We have too much to learn.我们要学的太多了（不定式作定语）。
⒊不定式短语还可作独立成分，用于句首、句中或句末。如：
To tell the truth,the play was a great disappointment tome.
常见的短语有to be exact（确切地说），to begin with（首先），to do him justice（说句对他公道的话），to be sure（真的）等等。
七、动词不定式、动名词的其它用法
⒈疑问词＋不定式结构
疑问词who,what,which,when,where,whether,how后可接不定式构成不定式短语，在句中作主语、宾语、表语等。如：
①When to leave for London has not been decided yet.
②Mr. Smith didn't know whether to leave or stay there.
③I asked Professor Xu how to learn English well.
④The question was where to get the medicine needed.
以上例句中疑问词＋不定式部分，均可转换为相应的从句形式。如：①When we shall leave…③…how I could learn…
经常在这种结构中使用的动词有：consider,decide,discover,explain,find out,forget,hear,know,lea rn,observe,understand,wonder等。
⒉动词不定式的时态、语态
(1)时态
①一般式：动词不定式一般式表示的动作发生在谓语动词之后，有时表示同时发生。如：
I hope to become a university student this year.（tobecome发生在hope之后）
We often hear Dick play the piano in the next room.（play和hear同时发生）
②完成式：表示的动作发生在谓语动词所表示的动作之前。如：
I'm sorry to have kept you waiting.
W e are too young to have seen the old society.
③进行式：表示的动作与谓语动词同时发生。如：
The teacher happened to be correcting our papers when Icame in.
They seemed to be discussing something important.
(2)语态
如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者，不定式一般要用被动语态形式。如：It's a great honour to be invited to Mary's birthday party.（不定式作主语）
It was impossible for lost time to be made up.（不定式作主语）
I wish to be sent to work in the country.（不定式作宾语）
Can you tell me which is the car to be repaired?（不定式作定语）
He went to the hospital to be examined.（不定式作状语）
在There be结构中，修饰主语的不定式可用被动，也可用主动。如：There are still many things to t ake care of (to be taken care of).但有时两种形式表达的意思不同，如：These is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.)
⒊动名词的时态、语态
(1)时态
①一般式：动名词的一般式所表示的动作可以是泛指，也可与谓语动词同时发生，或发生在谓语动作之前、之后。如：
W e are interested in collecting stamps.
I shall never forget seeing the Great Wall for the firsttime.
W e are not afraid of dying.
②完成式所表示的动作发生在谓语动词之前。如：
Lmagine having travelled on the moon.
We were praised for having finished the work ahead of time.
(2)被动语态
①如果动名词的逻辑主语为动名词所表示的动作的承受者，动名词要用被动语态，动名词的被动语态有一般式与完成式之分。如：
The young man came in without being noticed.
He prided himself on having never been beaten in class.
②有些动词后的动名词用主动形式，但表示被动意义。如：
The bike needs repairing.
If a thing is worth doing, it is worth doing well.
⒋在口语中，为避免重复，常用"to"代替不定式结构，有时甚至可以把to省略。如：
①—Did you go to visit the Great Wall?
—No,I wanted to,but there wasn't enough time.
②—Would you like to come to a party?
—I'd love to.
③—Don't make any mistakes in your homework,will you?
—I'll try not to.
④—Try to be back by 12,won't you?
—OK,I'll try.
另外，be going to,ought to,used to等也常用于这一结构中。
⒌在why引起的问句中，省略"to"。如：
Why spend such a lot of money?
Why not wait for a couple of days?
⒍当两个或更多作用相同的不定式并列使用时，只在第一个不定式前加"to"。如：
It's quite necessary for us to read more and have morepractice.
⒎"to"在下列短语中是“介词”，后接动名词或名词形式。如：
devote…to,face up to（勇敢地面对），look forward to（盼望），object to（反对），take to（养成习惯，对……感兴趣；开始从事某种活动），be used to（习惯于）等。
不定式的用法
不定式的用法
不定式由“to + 动词原形”构成，其否定形式是“not to + 动词原形”。不定式可以带宾语或状语构成不定式短语，没有人称和数的变化，但有时态和语态的变化。不定式可作主语、宾语、状语、表语和定语，但不能单独作谓语。不定式的逻辑主语有时有“for + 名词或代词宾格”构成。
1．不定式的用法
1）作主语。不定式短语作主语时，往往放在谓语之后，用it作形式宾语。如：To see is to believe.
It is right to give up smoking.
2）作宾语。不定式短语作宾语时，如果还带有宾语补足语，往往把不定式宾语放在宾语补足语之后，而用it作形式宾语。如：
He wanted to go.
I find it interesting to study history.
有些动词后只能用动词不定式作宾语，必须跟动名词。如：decide，plan，desi re，expect，hope, wish，pretend，promise，refuse，afford，agree，ask，fail，tend，pretend，manage
3）作宾语补足语。如：
He asked me to do the work with him.
注意：在feel，hear，notice，observe，see，watch，have，let，make等词后的补足语中，不定式不带to。但这些句子如果变成被动结构时，就必须带to。如：
I often hear him sing the song.
He is often heard to sing the song.
注意：动词不定式在介词but后面时，如果介词之前有行为动词do的各种形式，那么，这些介词后的不定式不带to，否则要带to。另外，在can’t choose but
和can’t help but等后面的不定式也省略to。如：
She could do nothing but cry.
I have no choice but to go.
4）作定语。如：
I have some books for you to read.
①作定语的不定式如果是不及物动词，或者不定式所修饰的名词或代词是不定式动作的地点、工具等，不定式后面须有相应的介词。如：
He is looking for a room to live in.
There is nothing to worry about.
Please give me a knife to cut with.
但是，不定式所修饰的名词如果是time，place或way，不定式后面的介词习惯上省去。如：
He had not money and no place to live.
②当作定语的不定式所修饰的名词或代词是不定式动作的承受者时，不定式既可以用主动语态，也可用被动语态，但其含义有所不同。试比较：
Have you anything to send ?
（你有什么东西要寄吗？——不定式to send的动作执行者是“你”）
Have you anything to be seat.
[你有什么要（我或别人）寄的东西吗？——不定式to be sent的动作执行者是“我”或“别人”]
5）作状语，表示目的、原因、结果或条件。如：
I came here to see you. （目的）
We were very excited to hear the news. （原因）
He hurried to the school to find nobody there. （结果）
To look at him, you would like him. （条件）
目的状语还可以用in order to或so as to来表示但so as to不能置于句首。如：In order to pass the exam, he worked very hard.
We ran all the way so as not to be late.
不定式也可以在作表语用的形容词后面作状语。如：
I am very glad to hear it.
The question is difficult to answer.
“too +形容词或副词+ 不定式”作状语。如：
He is too old to do that.
另外，句子中有enough这个词时，常用不定式作状语。例如：
The room is big enough to hold us.
6）作表语。如：
My job is to help the patient.
7）作独立成分。如：
聚焦动词-ing形式作状语 动词-ing形式作状语,可以表示时间、原因、方式、伴随、条件、结果等。如: 1. While reading the book, he nodded from time to time. (时间) 2. Being ill, he didn’t go to school yesterday.(原因) 3. He came running back to tell us the news. (方式) 4. She sat at the desk reading a newspaper. (伴随) 5. Working hard, you will succeed. (条件) 6. The child fell, striking his head against the door and cutting it. (结果) 注意:①动词-ing形式作状语,其逻辑主语应与句子的主语一致。 ②动词-ing形式前可有while, when, unless, though, if等连词。 [巩固练习] 从A、B、C、D四个选项中,选出可以填入空白处的最佳选项。 1. “We can’t go out in this weather,” said Bob, ______ out of the window.

动词后加－ing的规则 1．英语动词加-ing，通常是在原形词尾直接加-ing构成：cough—coughing，climb—climbing，stand—standing，fight—fighting 2．以-e结尾的动词 （1）如果动词原形以一辅音加一不发音的-e结尾，一般应去掉e再加ing：write—writing，hope—hoping，care—caring，stare—staring，plane—planing，have—having，save—saving，produce—producing，breathe—breathing （2）以-ie结尾的动词应先将e去掉，将i变成y然后再加-ing： die—dying，tie—tying，vie—vying，lie—lying （3）以-ee，－oe，－ye结尾的动词加-ing时应保留词尾e： see—seeing，flee—fleeing，free—freeing，agree—agreeing，hoe—hoeing，dye—dyeing，eye—eyeing （4）以-ue结尾的动词大多应先去e再加-ing： sue—suing，imbue—imbuing，construe—construing，pursue—pursuing， rue—ruing 有时，词尾e可去掉也可保留： glue—gluing或glueing，cue—cuing或cueing，blue—blueing或bluing， true—truing或trueing，clue—clueing或cluing 3．以一元音加一辅音结尾的动词 （1）如果动词最后一音节为重读闭音节，最后一个字母需要重复： run—running，stop—stopping，hop—hopping，plan—planning，star—starring，control —controlling但辅音x是个例外，无需重复（x其实起着两个辅音的作用）：tax—taxing，relax—relaxing （2）如果动词最后一个音节为次重读音节，最后一个字母有时也重复：kidnap—kidnapping或kidnaping，program—programming或programing （3）如果动词最后一个音节为非重读音节，最后一个字母大多无需重复：open—opening，offer—offering，audit—auditing但在有些动词中，重复或不重复均可：worship—worshiping或worshipping，focus—focusing或focussing，cancel—canceling或cancelling，travel—traveling或travelling 以非重读的-el结尾的动词加-ing时，英国英语习惯于重复词尾l，而美国英语则习惯于不重复1。 4．若动词以一元音加一半元音（y或w）结尾，可直接加-ing： pay—paying，throw—throwing，follow—following，draw—drawing，employ—employing 5．以-ic结尾的动词应先在字母c后加一字母k再加-ing： frolic—frolicking，panic—panicking，mimic—mimicking，picnic—picnicking，traffic—trafficking 这主要是为在动词后加-ing之后保留/k/这个音。若不在字母c后加字母k而直接加-ing，字母c的发音就不再是/k/，而是/s/： lesson 31 重点：动词的时态 时态：在英语语言中，同一个谓语动词在不同的句子中，发生的时间不一致的时候，必须用这个动词的不同形态。这种因为动词时间不同而形态不同的语法现象叫时态。 现在进行时 1．概念：1）表示此时此刻正在发生；2）一段时间内有间隔的在发生。 2．谓语构成：be动词+动词的现在分词（动词的ing形式）
动词-ing形式作表语定语，宾补及状语的用法 一、动词-ing形式作表语 1.表示主语的内容,可以转换到句首作主语 Her job is keeping the lecture hall as clean as possible. (= keeping the lecture hall as clean as possible is her job) 她的工作是尽量使报告厅保持干净。 2.表示主语具有的特征、性质和状态(动词ing相当一个形容词） The problem is quite puzzling. 这个问题很令困惑。 3.常用来作表语的现在分词有astonishing, amusing, confusing, disappointing, boring, encouraging, inspiring, moving, tiring, interesting, surprising等。 全析提示：动词-ing形式作表语时，其逻辑主语往往是句子中的主语，但用作表语的-ing形式也可带有自己的逻辑主语。 What worries me most is her staying too late every night. (staying too late every night的逻辑主语是her) 二、动词-ing形式作定语 1单个的动词-ing形式可以作前置定语，一般具有两种含义。 ①说明被修饰名词的用途和性能。 a reading room = a room which is used for reading 阅览室 running shoes =shoes for running 跑鞋 a working method =a method for working 工作方法 ②表示所修饰的人或物的动作或状态，在意思上接近一个定语从句，可以表示正在进行的动作，也可表示经常性动作或当时的状态。 developing countries = countries that are developing 发展中国家 an ordinary-looking house = a house that looks ordinary 看起来很普通的房子 a puzzling problem = a problem that puzzles somebody 困扰人的问题 2作定语的动词-ing形式如是一个短语，则应放在被修饰词的后面,做后置定语，相当于一个定语从句。 They lived in a house facing south.(=which is facing south) 他们住在一所朝南的房子里。 Do you know the boy playing basket?（=Who is playing basket) 你认识在打篮球的那个小男孩吗？ The man visiting Japan (=the man who is visiting Japan ) is my uncle 正在访问日本的那个男人是我的叔叔。 三、动词-ing形式作宾补 1、动词-ing形式作宾语补足语常放在宾语后 面，表示一个正在进行的主动性的动作，强调一个过程或一种状态。 When we returned, we found a stranger standing in front of the house. 2、当主句转换为被动结构时,原来作宾语补足语 的动词-ing形式便转换为主语补足语。
动词后加－i n g的规则 1．英语动词加-ing，通常是在原形词尾直接加-ing构成：cough—coughing，climb—climbing，stand—standing，fight—fighting 2．以-e结尾的动词 （1）如果动词原形以一辅音加一不发音的-e结尾，一般应去掉e再加ing： write—writing，hope—hoping，care—caring，stare—staring，plane—planing，have—having，save—saving，produce—producing，breathe—breathing （2）以-ie结尾的动词应先将e去掉，将i变成y然后再加-ing： die—dying，tie—tying，vie—vying，lie—lying （3）以-ee，－oe，－ye结尾的动词加-ing时应保留词尾e： see—seeing，flee—fleeing，free—freeing，agree—agreeing，hoe—hoeing，dye—dyeing，eye—eyeing （4）以-ue结尾的动词大多应先去e再加-ing： sue—suing，imbue—imbuing，construe—construing，pursue—pursuing，rue—ruing 有时，词尾e可去掉也可保留： glue—gluing或glueing，cue—cuing或cueing，blue—blueing或bluing，true—truing或trueing，clue—clueing或cluing 3．以一元音加一辅音结尾的动词 （1）如果动词最后一音节为重读闭音节，最后一个字母需要重复： run—running，stop—stopping，hop—hopping，plan—planning，star—starring，control—controlling但辅音x是个例外，无需重复（x其 实起着两个辅音的作用）： tax—taxing，relax—relaxing （2）如果动词最后一个音节为次重读音节，最后一个字母有时也重复：
现在进行时动词加ing的变化规律 1)一般情况下，直接加 -ing: 如：go—going answer—answering study—studying be—being see—seeing [注一] 和名词复数、一般现在时动词第三人称单数加-s(-es)不同， 动词末尾如为“辅音字母 + y”时，y不变，其后直接加ing。 如: study—studying fly—flying carry—carrying [注二] 动词结尾为辅音字母r时，加-ing，r在此必须发音。 如: water—watering answer—answering wear—wearing 2)以不发音的e结尾的动词，去掉e，再加ing 如：come—coming write—writing take—taking become—becoming 3)动词是闭音节的单音节词，或是以重读闭音节结尾的多音节词， 而末尾只有一个辅音字母时，这个辅音字母须双写，然后再加ing。 如：sit—sitting run—running stop—stopping begin—beginning admit—admitting forget—forgetting [注一] send，think，accept等动词虽是闭音节或以重读闭音节结尾， 但末尾有一个以上的辅音字母，因此，这个辅音字母不双写，应直接加ing。 如：sending thinking accepting 4)少数几个以-ie结尾的动词，须将ie变作y，再加ing。 如：die—dying tie—tying lie—lying躺，说谎 5)少数以-c结尾的动词变为现在分词时和过去式，须先将-c变为ck,然后再加-ing 或-ed 。 如：picnic—picnicking (picnicked) traffic—trafficking (trafficked)
高中英语语法 动词ing形式做宾补表语定语状语用法详解及练习 第一部分：动词的-ing形式作宾语补足语 1．动词的-ing形式可以在see, hear, notice, watch, feel, smell, look at, listen to, observe, find等表示感官和心理状态的动词后面作宾语补足语，和一个名词或代词一起构成复合宾语。 We heard the children shouting upstairs. 我们听见孩子们在楼上叫喊。 I noticed a man running out of the bank when I got off the car. 我下车的时候注意到一个男人从银行里跑出来。 I felt my heart beating violently. 我觉得我的心在猛烈地跳动。 2．动词的-ing形式和不定式作宾语补语的区别 在see, hear, feel, watch, notice等感官动词后，既可用动词的-ing形式构成复合宾语，也可用不定式构成复合宾语，两者之间有一定的区别。用动词的-ing形式时，表示动作正在进行；用不定式时，表示动作发生了，即动作的全过程结束了。 He saw a girl getting on the car. 他看见一个女孩在上汽车。 ) (She was getting on the car.) He saw a girl get on the car and drive off. 他看见一个女孩上车开走了。 (She got on the car and drove off.) Do you hear someone knocking at the door 你听见有人在敲门吗 (Someone is knocking at the door.)

1.v-ing作状语可以修饰动词，在句中表示时间、原因、结果、条件、让步、行为方式或伴随的情况等。 **时间状语 动词的ing形式作时间状语时相当于一个状语从句，几乎每一个动词ing作状语时都可以转换成一个时间状语从句。它表示动作如果和谓语动词的动作同时发生或紧接着发生，此时常用动词的ing形式的一般式，在强调动词的ing形式表示的动作先于谓语动词的动作时，用动词ing的完成时。 Eg；1.arriving in Paris，I lost my way。 =when I arrived in Paris，I lost my way。到巴黎后，我迷路了。 2.Hearing the exciting news，the boy jumped with joy。 =when the boy heard the exciting news，the boy jumped with joy。 听到这个令人激动的消息，男孩高兴得跳起来。 3.we are ready for the examination，having made full preparations。 = we are ready for the examination，when we have made full preparations。 我们已经做好充分的准备，现在可以应考了。 **原因状语
动词的ing 作原因状语时，相当于一个原因状语从句，同时也可以转变为一个原因状语从句。它表示的原因的动词ing 形式短语一般置于句首。 Eg；1.having smoked too much ，he has suffered from lung cancer。 =as he has smoked too much ，he has suffered from lung cancer 由于抽烟过多，他得了肺癌。 2.living far from my company，I have to get up early。 =because I live far from my company，I have to get up early。 由于住得离公司远，我只好早起。 3.not knowing her address，I might as well call her to come over。 =because I do not know her address，I might as well call her to come over。 不知道她的地址，我只好打电话让她来。 **结果状语 动词的ing作结果状语时，不常用，通常放在句末，中间有逗号。它可以转化成结果状语从句。 Eg；1.the fire lasted nearly a month，leaving nothing valuable。 大火持续了近一个月，几乎没剩下什么有价值的东西。 **方式、伴随状语 动词ing表示方式或伴随情况是比较常见的，它用来说明发生的背景或情况。 Eg，1.I stood by the door，not daring to say a word。 我站在门旁边，不敢说一句话。 2.my parents wrote me a letter ，telling me to change my job。 我父母来信让换我工作。 3.i lay on the grass，staring at the sky for a long time。 我躺在草地上，长时间的望天空。 4.talking and laughing，the kids walked one by one into the classroom。 孩子们有一个个说有笑的走进教室。 5.theycame running all the way。 他们一路跑过来。 **条件状语
动词加-ing 之变化规则 1. 首先了解一下“闭音节”的基本知识：以辅音结尾的音节称为“闭音节”，如果这个闭音节在单词里是重读的，则这个音节叫做“重读闭音节”； 2. 如果一个动词以“重读闭音节”结尾，则其现在分词/动名词的构成通常是“双写词尾的那个辅音字母，再加- ing”； 3.请注意：以“辅音字母结尾”和“以辅音结尾（指发音或音标）”是不同的。 4. “双写词尾辅音字母后加ing”必须同时满足以下 4 个条件： 1) 该动词的发音以重读闭音节结尾； 2）结尾闭音节符合“1 个辅音字母+ 1 个元音字母+ 1 个辅音字母” 3）结尾的辅音字母不是"x"； 4）该动词的拼写规则没有例外； 请看下面的例子： begin - beginning: 以 1 个辅音字母结尾、重读，符合上述全部条件； reject - rejecting： 不要双写"t"，因为结尾有 2 个辅音字母； bleed - bleeding；不要双写"d"，最后那个辅音字母前有 2 个元音字母，不符合上述条件2）； rabbet (vt.嵌接) - rabbeting：不要双写"t"，因为重读音节在第 1 个音节上，不符合条件1）；control - controling 或controlling 都可以，加ing 前，结尾的"l" 可以不双写拼写，这是“拼写例外”的情形。 kidnap - kidnapping 或kidnaping 都可以，加ing 前，结尾的"p" 可以不双写拼写，也是“拼写例外”的情形。
fix - fixing 单词结尾的辅音字母是“x”时，不要双写； 综上所述，没有必要将“需要双写词尾辅音字母然后加ing”的单词一一列出，只要你知道了上述规则，你基本上“错不了”！ 补充 begin-beginning stop-stopping swim-swimming shop-shopping singing running falling giving helping coming getting cooking putting shopping swimming running getting chatting letting stopping beginning hitting fitting pitting knitting kidding 重读闭音节中以一个元音字母和一个辅音字母结尾才双写。 Answer B: clean, + ing 时后也不用双写n ，因为它中间的是ea /i:/ 字母组合比如：heat - heating feel - feeling dealing sealing healing leaning beating meeting ---------- 如果是i的话就要咯 hitting sitting fitting .... ---------- 之所以要双写辅音字母,就是为了将闭音节和去e的开音节区别开来假如： bit 和bite 都写成biting, 那就无法分辨了但是在英语中几乎不可能出现-eane, -eate, -eape 这些开音节(有的话...是我才疏学浅)..也没有eet, eep, eed..构成闭音节..不会带来上述的混乱 所以带元音字母组合的"伪闭音节"通常不需要双写最后一个辅音字母 Answer C为什么重读闭音节需要双写辅音字母呢? 因为如果不双写的话, cuting 会被认为是cute (注意!只是举例,cute并没有这种用法) 加上-ing. 所以,双写辅音字母起到提示闭音节的作用,区分单词。 Answer D: order 也不要双写末尾字母，词尾是重读闭音节才要双写。 闭音节就是所谓的元音字母不是发它本身的字母音，重读闭音节就是指在一个音节中，以辅音音素结尾的而且是重读音节的音节比如apple 划音节就应该是ap/ple 前面那个
动词ing形式的用法及变化规则 一．动词ing形式的用法 1.正在进行时中,谓语动词后加ing. 如:I'm playing football. 2.一些特殊表达..如: be good at doing sth enjoy doing sth. be busy doing feel like doing thank you for doing do some cooking/cleaning/reading/shopping/washing go swimming/fishing/shopping/skating/boating 二．动词现在分词由动词原形在词尾加ing构成，其规则如下： 1）一般情况下直接加ing think---thinking sleep---sleeping study---studying speak---speaking carry---carrying say---saying 2）以不发音的字母e结尾的单词，去掉字母e，再加ing wake---waking make---making come---coming take---taking leave---leaving have---having 3）以重读闭音节结尾，呈现“辅，元，辅”结构的动词，先双写末尾的辅音字母，再加ing 。初中学过的这类词有：begin，cut, get, hit, run, set, sit, spit, stop, swim, beg, drop, fit, nod, dig, forget, regret, rid, 等。 (visit 不是以重读闭音节结尾，不用双写) travel虽然重读第一音节，词尾音节不重读，但是现在分词仍要双写末尾辅音字母，然后再加ing ，如：travel---travelling.初中阶段此类词只有这一个。4）以 y 结尾的动词直接加 ing carry—— carrying enjoy—— enjoying 5）以ie结尾的动词，把ie改为y ，再加ing
