㈠ 英语的八大时态讲述和讲解，最好有例题，，非常感谢。
1. 一般现在时表示现阶段经常或习惯发生的动作或存在的状态,或说明主语的特征。
①一般现在时句子中常有的时间状语：often, usually, sometimes, always, every (day等), once/twice, a (week等), on (Sunday等), never, in the (morning等)。如：They go to the Palace Museum once a year.(他们每年去一次故宫)/ They often discuss business in the evening.(他们经常在晚上商谈生意)

③ 表示十分确定会发生(如安排好的事情)或按照时间表进行的事情,用一般现在可以表达将来,句子中可以有将来时间。如：The train for Haikou leaves at 8：00 in the morning.(开往汉口的列车上午8点开车)
④ 在时间状语从句中(以when, after, before, while, until, as soon as等引导)和条件状语从句中(以if,unless引导),用一般现在时代替一般将来时,句子可以有将来时间。如：Please ring me up as soon as you arrive in Germany.(你一到德国就给我打电话) / If it rains tomorrow,we will have to stay at home.(如果明天下雨我们就只好呆在家)

3. 一般将来时 表示将来某一时刻或经常发生的动作或状态。
①一般将来时的时间状语有：tomorrow，this (afternoon), next (year), one day, now, soon, someday, sometime, in the future, when引导的从句等。

③“am/is/are going to+动词原形”表示打算或准备要做的事情,或者主观判断即将要发生的事情。It’s going to rain soon.(天快要下雨了)
④表示一个人临时决定要做某事,可以用will表达。如：I will go to the lab to get some chemicals(化学药剂). So please wait until I return.(我要到化学实验室去取些药品,请等我回头)
⑤现在进行时、一般现在时也可以表示将来。(见相应时态)
⑥shall和will 在口语的一些疑问句中相当于情态动词。Shall一般与第一人称连用,will与第二人称连用。如：Shall we go to the zoo next Saturday?(我们下周六去动物园好吗？)/ Will you please open the door for me?(替我把门打开好吗？)
4. 现在进行时 现在进行时表示现在正在进行的动作或是现阶段正发生
此刻不一定在进行的动作。
①现在进行时由“助动词be (am is are ) +现在分词”构成。
②现在进行时的时间状语有： now, this …, these…等,但经常不用。如：What are you doing up in the tree?(你在树上干什么？)/ I am writing a long novel these days.(我最近在写一本长篇小说)
③表示即将发生的动作,一般指近期安排好的事情。常见的动词有：come, go, stay, leave, spend, do等。如：I’m coming now.(我就来)/ What are you doing tomorrow?(你明天干什么？)/ He is leaving soon.(他就要走了)
④表示频繁发生或反复进行的动作,常与always等频度副词连用,以表示赞扬、不满或讨厌等感情色彩。如：He is always borrowing money from me and forgetting all about it some time later.(他老是向我借钱,过一些时候就忘得一干二净)
5. 过去进行时 过去进行时表示过去某一时刻或某阶段正在进行的动作。①过去进行时由“was(第一、三人称单数)或were(第二人称单数和各人称的复数)+现在分词”构成。
②过去进行时的时间状语有：then, at that time, this time yesterday, at (eight) yesterday (morning),(a year) ago, 以及由when引出的时间状语从句。如：He was cooking supper this time yesterday.(昨天这个时候他正在做晚饭)/ The little girl was playing with her toy when I saw her.(我看到小女孩的时候她正在玩玩具)
③用于宾语从句或时间状语从句中,表示与主句动作同时进行而且是延续时间较长。句子中通常不用时间状语。如：She saw it happen when she was walking past.(她路过时看到事情的发生)/ They sang a lot of songs while they were walking in the dark forest.(他们在黑暗的森林里走时唱了很多歌)
④也可以表示过去一个阶段频繁发生或反复进行的动作,常与always等频度副词连用,以表示赞扬、不满或讨厌等感情色彩。如：He was always borrowing money from me when he lived here.(他住在这里时老向我借钱)
6. 现在完成时 现在完成时表示一个发生在过去的、对现在仍有影响的动作,或表示开始在过去,并且一直延续到现在,甚至还可能延续下去的动作。
①在完成时由“助动词have (has)+动词的过去分词”构成。
②表示发生在过去的对现在仍有影响的动作时,时间状语有：already, yet, just, once, twice, ever, never, three times, before, in the past+一段时间等。如：I have never seen such fine pictures before. (我以前从来没有看过这么好的画)/ He has just gone to England.(他刚去英国)
③表示在过去开始一直延续到现在(可能延续下去)的动作或状态时,时间状语有：for (two years),since 1990, since (two weeks ago)和since引导的状语从句。如：I have been away from my hometown for thirty years.(我离开家乡有30年了)/ Uncle Wang has worked in the factory since it opened.(自从这家工厂开张,王叔叔一直在那儿工作)
④口语中have got往往表示have(有)的意思。如：They have got thousands of books in their library.(他们图书馆有上万本书)
⑤have been to与have gone to的区别：have gone to(“已经去了”)表示人不在这里,have been to(“去过”)表示人在这里。如：--Where is Mr. Li? –He has gone to the UK. (李先生在哪里？他去了英国。)/ --Do you know something about Beijing? –Yes, I have been to Beijing three times. (你知道北京的情况吗？是的,我去过那里三次。)
⑥在完成时中,一个瞬间性动词(一次性动作)不能与表示一段时间的状语连用, 此时须将该瞬间动词改为延续性动词或状态动词。或者使用下面这个句型：It is/ has been + (多久)+ since +主语(人)+谓语(过去时)+……+过去时间状语
[注意] 在其它的时态中也存在类似问题,记住,关键是：瞬间动词不能和表达一段时间的状语连用。如：How long may I keep the book?(这本书我能借多久？)(句子中keep取代了borrow)
8. 过去完成时 过去完成时表示过去某一时间或某一动作发生之前已经完成的动作。简言之, 过去完成时所表示的时间是“过去的过去”。
①过去完成时由“助动词had+动词的过去分词”构成。
②过去完成时时间状语有：by (yesterday), by then, by the end of (last…)或者由when, before等引出状语从句。有时句子中会有already, just, once, ever, never等词语,也会有for… 或since…构成的时间状语。如：They had already finished cleaning the classroom when their teacher came.(当老师来的时候他们已经打扫完了教室)/ The woman had left before he realized she was a cheat.(在他发觉那个妇女是个骗子时她已经走掉了)
③过去完成时常用于宾语从句中、after引导的从句中,或者从句是before引导的主句中。如：After I had put on my shoes and hat, I walked into the darkness.(我穿上鞋子戴上帽子走进了黑暗之中)/ He said that he had never seen a kangaroo before.(他说他以前从来没有见过袋鼠)
8. 过去将来时 过去将来时表示在过去预计将要发生的动作或存在的状态。
①过去将来时由“助动词should(第一人称)或would(第二、三人称)+动词原形”构成。在美国英语中,过去将来时的助动词一律用“would +动词原形”。
②过去将来时常由于宾语从句中,时间状语有：later, soon, the next (day).
③在时间状语从句和条件状语从句中不可以使用过去将来时,而应该使用一般过去时。如：He promised that he would pay me a lot if I helped him with the project.(他答应付给我许多钱如果我帮助他搞那个项目)/ Every time when he was free, he would sit down and read some books.(每次只要他有空他就会坐下来看看书)
④表示纯粹的将来时用would或should,表示打算或主观认为的事情用was/were going to (+动词原形)。如：She told me she would be 18 the next month.(她告诉我她下个月就18岁了)/ She told me that she was going to have a walk with her pet dog.(她告诉我她打算带她的宠物狗去散步)
⑤过去将来时还可以表示一个过去经常性的动作。如：When it rained in the day, he would bring an umbrella with him.(白天下雨时他会随身带一把雨伞)

㈢ 英语语法总结，所有的
一、非谓语动词
“非谓语动词”可分为动词不定式、动名词和分词。它在句子中的作用很多：除了不作谓语外，它可以充当主语、宾语、表语、定语、状语与复合宾语(主语补语或宾语补语)。有些及物动词后面接不带to的不定式作复合宾语。这些动词归纳如下：一感(feel)．二听(hear，listen to)，三让(have，1et， make)，四看(see，watCh，notice，observe)。再加上help somebody(to)do something和美国英语look at somebody do somthing。还有“二让”属特殊：get somebody to do something 与keep somebody doing。而有些及物动词后面接动名词(the -ing form)作宾语。这些动词归纳为一句话：Papa C makes friends。这是由如下动词的开头字母组成：permit，advise， practise，avoid,consider,mind, allow,keep,enjoy,suggest, finish，risk，imagine,escape,need，delay，stand(忍受)。 为了容易记住，也可以编成顺口溜：“允许完成练习，建议避免冒险，考虑延期逃跑，喜欢保持想象，需要反对忍受”。其相对应的动词依次是：permit/allow,finish,practise；
advise／suggest， avoid，risk： consider， delay， escape／miss； enjoy／appreciate， keep， imagine； need/want／require,mind． can't help／can’t stand。
二、复合句
1、学生最容易混淆的是定语从句与同位语从句的区别。
例如：A、The news that our team has won the match is true． (同位语从句)
B、The news that he told us surprised everybody here． (定语从句)
关键的区别在于连接或关系代词that：有意义的是定语， 无意义的是同位。因为引导定语从句的that在从句中作主语或 宾语，而引导同位语从句的that只起到连接词的作用。
2、接着容易混淆的是引导定语从句的关系代词that与 which：that之前是不定(代词)、序数(词)、(形容词)最高级：which之前是介词短语与逗号(非限制性)。
例如：A、All that we have to do is to practise every day．
B、The first lesson that I learned will never be forgotten．
C、I have lost my pen，which I like very much.
D、The house in front of which there is a garden is my home．
三、It的用法
1、It除了代替人和物以外，还可以作形式主语。而真正的主语(不定式、动名词或从句)则放于谓语或表语之后。
例如：It is nor easy to finish the work in two days.
然而有少数表语之后接动名词作真正的主语。这些表语是：无助(no help)、无用(no use)、没好处(no good)；工作(hard work)、费时(a waste of time)、又危险(a danger)。
例如：A、It is no use crying over spilt milk.
B、It is a waste of time waiting for him．
2、It还可以作形式宾语。通常下列动词后面可接it作形式宾语：2f2tcjm(find，feel,think,take,consider，judge, make)。
例如：A、He made it clear that he was not interested in this subject．
B、I think it no use arguing with him.
3、It用于强调句式。要强调句子的某一部分(主语、宾语、 状语)，可以把it当作先行词。这种句子的结构是：It is(was)+ 被强调部分+that(who)+句子的其余部分。
例如：A、It iS Professor Lin who teaches us English—(强调主语)
B、It was in Shanghai that l saw the film.—(强调状语)
C、It was in 1990 that I worked in the factory．(同上)
但要注意与定语从句的区别。
例如：D、It was 1990 when I worked in the factory．(定语从句)
在强调句式里，我们把强调结构It is(was)…that除去，句子还很完整。如例句C。而例句D就不能。
四、倒装结构
学生容易混淆的是全部倒装与部分倒装。如何区分之，编个顺口溜：副(adv.)介(prep．)提前全倒装，其它句式部分倒；否定提前倒助动，让步状语倒表语；复合句式倒主句，不
倒装的属特殊。下面举例说明：
A、Here comes the bus．(副词提前，全倒装)
B、Here he comes.(代词作主语，不倒装)
C、In front of the house lies a garden.(介词短语提前，全倒装)
D、Never shall I do this again.(否定词提前，部分倒装)
E、Young as he is ,he knows a lot.(让步状语从句，表语倒装)
F、Only when he told me did I realize what trouble he was in．(only 修饰状语，主句倒装)
G、Only he can save the patient.(only修饰主语．不倒装)
H、Not only will help be given to people,but also medical treatment will be provided.(否定词提前，部分倒装)
I、Not only he but also we like sports.(连接两个主语，不倒装)
五、虚拟语气
虚拟语气也是一个难点。所谓虚拟语气是表示说话人的愿望、假设、猜测或建议，而不表示客观存在的事实。它通过句子的谓语动词的特殊形式来表示。现归纳如下：纯假设，用虚拟，动词时态退一级：条件句，分主从，主句谓语前加would (should,could，might)；表愿望,用虚拟，wish后面接宾语(从句)：现在过去与将来，动词时态退一级：提建议，用虚拟，宾语(从句)动词用(should)do：俩建议，三要求，再加坚持与命令(suggest,advise,demand,require,request,insist,order)：It is time和eoukd rather,后接丛句用虚拟：部分主语从句中， 谓语用虚拟结构 (It is necessry /important/natural/natural/strange/strange that……should do)。 下面举例说明：
A、If you came tomorrow,we would have the metting. (条件句虚拟)
B、Without air,there would be no living things.(同上)
C、We wish we had arrived there two hours earlier.(表示愿望虚拟）
D、He demanded that we (should)start right away.(表示建议虚拟)
E、It is(high)time that we left (should leave)now．(特殊从句虚拟）
F、I would rather you gave me the book．(同上)
G、It is necessary that we should clean the room everyday，(主语从句虚拟)
H、He speaks English so fluently as if he were English． (特殊从句虚拟)
