15、一般现在时和现在进行时
一般现在时表示通常性、规律性、习惯性的状态或者动作，主语是单三时，动词有单三变化。
They often get up at 7:00. He often gets up at 7:00.
一般现在时，动词的单三变化，一般在动词尾加s：play-plays; 以字母s, x, ch和o结尾的动词加es， guess-guesses; 以辅音字母y结尾的动词，先变y为i再加es， study-studies.

17、将来时
一般将来时表示将来某一时刻的动作或状态，或将来某一时间内经常发生的动作或状态，常常和表示将来的时间状语连用。 tomorrow, next week, in the future
助动词will和shall + 动词原型， 表示将来发生的事

Be going to +动词原形 用来表示近期或事先考虑过的将要发生的动作，以及已有迹象表明必将发生某事，意为“打算，就要”
They are going to play football this afternon.
She is going to learn French next year.
Be doing 表示位置转移的动词：go, come, leave, start, arrive可用现在进行时表示将来时

过去完成时（had + 过去分词）表示句中的动作发生在过去之前，即过去的过去，已经完成，对过去造成了一定的影响或后果。

19、动词
动词根据功能分为四类：实意动词（notional verb), 系动词(link verb), 助动词(auxiliary verb), 情态动词(model verb)
动词有数量和时态的变化，时态通常有三大时态：现在，过去和将来；根据动作进行的状态可分为：一般时，进行时和完成时；使用动词时通常将上述结合。
20、情态动词
情态动词（Modal verbs）本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。
can/could 表示能力，用be able to可代替；can/could 表示现在/过去的能力；客观可能性（can的可能性大）
He can/could/is able to swim. ; He can/could come tomorrow. ; Can/could i stay here?
may/might 表示可能性，may 的可能性大，请求，允许用might 更委婉
He may/might come here by bus.
May/might i join you?
Should / ought to / must (have to)
Should 表示劝告，建议，命令，其同义词是ought to ；Should 强调主观看法，而ought to 强调客观要求，在疑问句中通常用Should代替ought to
You should/ought to do the job right now.
Should they stay here now?
Must /have to 表示必须，必要，Must 表示主观多一些，而have to则表示客观多一些
have to有时态和数量的变化，must 和 have to 二者的否定意义不大相同
You mustn't go. You don't have to.
need “需要” 1、情态动词；2、实意动词（有三单和时态的变化，后面加带to的不定时）
(model verb) He need come here early. ; He needn't come here early. ; Need he come here early?
(notional verb) He needs to come here early. ; He doesn't need to come here early. ; Does he need to come here early.
回答must 和 have to 的提问句时，否定使用needn;t , don't have to 等回答方式
Must i come here early tomorrow?
No, you needn't
had better / would rather
had better 表示“最好做某事”，had 虽然是过去式，但是不表征过去，better 后面接动词原形
He had better eat more. ; You'd better finish it right now.
Would rather 表示“宁愿，宁可，还是......为好”，语感上比had better 要轻。
You would rather deal with it now.
否定形式分别为：had better not + 动词原形 ； would rather not + 动词原形
He had better not eat more. ; You would rather not deal with it now.
Used to , would 表示过去习惯性动作，可翻译成“过去常常...”
used to 可指过去的状态或情况，would 则不可
The novel used to be popular.
Would 表示反复发生的动作，如果某一动作没有反复性就不可用would，只可用used to
He would practise englishc everyweek. ; I used to live in Beijing.
Used to 表示过去经常性或习惯性的动作或状态，现在已经结束，would 则表示有可能再发生
People used to believe that the earth was falt.
He would go to the park as soon as he was free.
情态动词的否定：情态动词+not+动词原形
can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would)
He can't sing an English song. ; He mustn't go here. ; He doesn't have to go here.
You oughtn't to have told them this bad news, but you did.
使用情态动词进行提问，情态动词+主语+动词原形
Can he sing an English song? ; Does he have to go there?
情态动词+have+过去分词： 表达过去的事实；有推测的含义
He can/could have arrived. He may/might have arrived. ; He must have arrived.
Should have +过去分词 (本应该......)；needn't have + 过去分词(本不需要......)
He should have arrived. ; They should have finished the work. ; You needn't have done so.
Must have + 过去分词 (准时已经......)；can't have +过去分词(不可能已经......)
He must have arrived. ; He can't have arrived.
can not…too\enough表示"无论怎样``````也不过分","越``````越好"：
You can't be too careful. 你越细心越好
21、被动语态
如果主语是动作的承受着，则用动词的被动语态做谓语
被动语态的构成：Be + 动词的过去分词......by sb.
He is taken to American by his mother. ; The information is needed by us. ; The book was being read by him. ; The computer could have been used by them.
被动语态也可以和情态动词结合
The food could be taken away. could可以替换成might be/must be/should be/needs (taking away)/had better be
Books used to be returned in two days.
被动语态的一般疑问句;助动词+主语+（其他助动词）+动词过去分词-
Is the information needed by hin? ; Has the computer been used by her? ; Will the room be cleaned?
被动语态的特殊疑问句：疑问词+助动词+主语+（其他助动词）+动词过去分词-
The infoemation is needed by them. What is needed by them?
The girl is taken to Shanghai. ; Where is the girl taken?
The book has read three times. ; How many times has the book been read?
22、to+动词原形与动词原形+ing （非谓语动词）
动词不定式：由to+动词原形构成，可以做主语、宾语、宾补、定语、表语和状语
主语：To get there by bike will take us an hour.
宾语：The driver failed to see the car in time.
宾补：We believe him to be guilty.
定语：The next train to arrive is from seoul.
表语和状语：My suggestion is to put off the meeting. ; I come here only to say goodbay to you.
动词原形+ing，可作动名词用，具有动词的特征和变化形式，但在句子中的用法及功能类同名词，在句子可以做主语、宾语、表语、定语。它也可以被副词修饰或者支配宾语
Reading is an art. ; They went on walking and never stopped talking. ; Your task is quickly cleaning the window. ; This is a reading room.
能跟动名词的动词有: avoid; consider; delay; dislike; endure; enjoy; escape; forgive; finish; imagine; keep; mind; miss; pardon; prevent; resist; suggest; understand; can't; help......
能跟不定式的动词有：decide; desire; expect; hope; mean; pretend; promise; refuse; undertake（承担）; want; wish; agree; manage
能跟动名词与不定式的动词有：love; like; hate; prefer; begin; continue; intend; attempt; propose; want; need; remember; forget; regret; try; deserve; start
动词后面跟动名词还是不定式，含义不相同，总的来说，表示习惯的，一般性的动作多跟动名词，一次性的具体的被动动作多跟不定式。
remember, forget. regret后面跟动名词时，动名词表示过去的动作，后跟不定式时，不定式表示将来的动作。
I remember meeting him in the street. ; I remember to write a letter to my parents.
stop + 动名词 表示停止动名词所表示的动作， stop +不定式 表示停下来，做不定式表示的动作。
Stop smoking, please. ; Let's stop to have a rest.
forget to do 忘记做...（未做）；forget doing 忘记已做...（已做）
同remember
see, watch, hear sb. do/doing（动作结束/动作在进行）
let; make; notice; hear; have; help; see; watch; feel (感官动词）省去to不定式做宾补，在改被动语态时省去的to还原。
Someone heard him sing in the room. ; He was heard to sing in the room.
what/How about doing ; be good at doing ; 介词 + doing
假主语、真主语、不定式/动名词的否定式
to 不定式或动名词可以在主语的位置上，但一般用it代替它作为形式主语
It 's a great honor to be invited. ; It is no use crying over spilt milk.
在宾语的位置上，用it代替它作形式宾语，这种情况it叫形式宾语
We think it important to learn English.
I found it pleasant walking in the park.
对动名词和不定式进行否定时，在不定式或动名词前加not否定就可以了
He pretended not to see her.
He regrets not join them.
to 不定式表目的
in order to +v 表示目的，由in order to 引导的目的状语置于句首，句尾均可
so as to +v 表示目的，由so as to 引导的目的状语置于句尾
I have written it down in order to remember it.
He shouted and waved so as to be noticed.
它们的否定形式分别在to前面加not
I have written it down in order not to forget it.
He said nothing so as not to be noticed.
常见的不定式与动名词，包含不定式和动名词的一些固定搭配
too...to... 太...以至于不能 The room is too small to live.
enough +n +to +v ; adj +enough +to +v 足够...可以...
There is enough food to eat. ; The box is big enough to contain six apples.
On +ving 一...就... On seeing the snake, the girl was very frightened.
There is no hope of +ving 没希望... There is no hope of seeing him.
feel like +ving 想要... I feel like eating ice cream now.
have a hard time +ving 做...艰难 They have a hard time solving the problem themselves.
现在分词、过去分词、分词句
ving 可称为动名词，也可称为现在分词 Writing books is his job. He is writing a book.
动词被动语态形式可称为动词的过去分词，用在完成时和被动语态当中
The students went out of the classroom, laughing and talking.
Accompanied by his friends, he went to the railway station.
Given better attention, the plants could grow better.
原形不定式，使役动词，表示“使/让......”
have,make,let 做使役动词构成形式为 have/make/let +宾语 +v
He made me laugh. ; I let him go. ; Please have him come here.
get 和 help 都做使役动词，get的使役动词句为：get +宾语 +to +v，help 的使役动词为“help +宾语 +(to) +v”.
I can't get anyone to do the work properly. ; I helped him to repair the car.
使役动词(have, make, let, get, help) +宾语 +过去分词，表示“让某物/人被别人...”
I must get my hair cut. ; He couldn't make himself heard. 被别人听到
Can you get the work finished in time?
感官动词 see, watch, observe, notice, hear, smell, taste, feel +宾语 +动词原形/现在分词

和使役动词相似，感官动词后可接过去分词，“感官动词 +宾语 +过去分词”
John saw the man knocked down by the car. 被撞倒。
23【假设】单纯表示条件
条件状语从句，用“if”引导条件状语从句，从句为现在时，通常译作“如果...”

if 引导的条件状语从句，可以放在句首，也可以放在句尾
if you ask him, he will help you. ; She will be upset if you fail the exam.
The cat scratches you if you pull her tail. (表示事实，不是将来发生，没有用will）

从句：动词过去式，Be用were
主句：would / could / should / might +动词原形
