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)
⑤ 一般现在时用于倒装句中可以表示正在发生的动作,动词以come, go为主。如:Here comes the bus. (车来了) / There goes the bell.(铃响了)。

①表示过去具体时刻发生的一次性动作时,时间状语有:at (eight) (yesterday morning),(ten minutes) ago, when引导的时间状语从句。如:I got up at 6:00 this morning.(我是早上六点钟起床的)/ Little Tom broke the window at half past nine this morning.(小汤姆今天早上九点半把窗子打破了)/ When he went into the room,he saw a stranger talking with his father.(他走进房间时发现一个陌生人正和他父亲谈话)

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。
②用will构成的将来时,表示动作与人的主观愿望无关。“shall”用于第一人称,“will” 用于所有人称。如:I will graduate from this school soon.(我很快就要从这所中学毕业了)/ You will stay alone after I leave.(我走了之后你就要一个人过了)
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)
