情态动词情态动词表推测的三种句式 1.在肯定句中一般用must (一定)，may（可能），might /can, could（也许，或许）。 （1）He must/may/might know the answer to this question? 他一定/可能/也许知道这个问题的答案。 2.否定句中用can’t / couldn’t(不可能), may not/might not(可能不)。 （1）It can’t/couldn’t be the headmaster. He has gone to America. 这不可能是校长，他去美国了。 3.疑问句中用can/could (能……?)。 （1）Could he have finished the task? 他可能把任务完成了吗？ （2）Can he be at home now? 他现在能在家吗？ 注：以上三种句式中情态动词的语气按程度都是依次递减的。Might, could并非may, can的过去式，而表示语气较为委婉或可能性较小。 （二）情态动词表推测的三种时态 1.对将来情况的推测，用“情态动词 + 动词原形”。 （1）She must / may / might / could arrive before 5. 5:00前她一定/可能/也许到。 2.对现在或一般情况的推测，用“情态动词 + be”，“情态动词 +be doing”或“情态动词 + 动词原形”。 （1）He must / may / might / could be listening to the radio now. 他一定/可能/也许正在听收音机。 注：情态动词 should /ought to表推测时，意为“想必会，理应……”但与“have +过去分词”连用时，则又可构成虚拟语气意为“本应该做某事却没做”。例如： （4）It’s seven o’clock. Jack should/ought to be here at any moment. 现在七点钟了，杰克理应随时到达。（推测） （5）She should / ought to have attended your birthday party, but she had to look after her mother in hospital. （虚拟） 她本该出席你的生日晚会的，可是她得在医院照顾她妈妈。 （6）Tom should not /ought not to have told me your secret, but he meant no harm. （虚拟） 汤姆本不该告诉我你的秘密，可是他并无恶意。助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词基本的有十四个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to.had better 上述两类助动词的共同特征是，在协助主动词构成限定动词词组名词性从句主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。宾语从句 名词从句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 表语从句 在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。例如： The fact is that we have lost the game. 事实是我们已经输了这场比赛。 That’s just what I want. 这正是我想要的。 【注意】whether 可引导表语从句，但与之同义的if却通常不用于引导表语从句。同位语从句 同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。

一般现在时表将来主要是：1）下列动词：come, go, arrive, leave, start, begin, return的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。 The train leaves at six tomorrow morning. When does the bus star? It stars in ten minutes.2）倒装句，表示动作正在进行，如： Here comes the bus. = The bus is coming. There goes the bell. = The bell is ringing.3）在时间或条件句中。When Bill comes (不是will come), ask him to wait for me.I'll write to you as soon as I arrive there.4）在动词hope, take care that, make sure that等后。I hope they have a nice time next week.Make sure that the windows are closed before you leave the room.下面这几种情况也算在内：一、当主句为将来时态或表示将来意义时，时间和条件的状语从句必须用一般现在时表将来。如：I’ll write to her when I have time. 我有空会给她写信。Turn off the lights before you leave. 走前关灯。If we hurry, we may catch the bus. 如果赶紧走我们可能赶得上公共汽车。Tell me in case you get into trouble. 遇到麻烦请告诉我。二、当主句为将来时态或表示将来意义时，表示让步、相似、比例的从句也必须用一般现在时表示将来。如：I’ll follow him wherever he goes. 他去哪儿，我就跟着去哪儿。Whatever you say, I won’t pay. 无论你说什么，我都不会付钱。Whether we help him or not, he will fail. 无论我们帮他与否，他都会失败。I’ll have a good time whether I win or lose. 赢也好，输也好，我都将会玩好。The more you eat, the fatter you will become. 你吃得越多就会越胖。三、当主句为将来时态时，定语从句也通常用一般现在时表将来。如：I’ll give you anything you ask for. 你要什么我都给你。You can have anything I find. 我找到的任何东西你都可以拿去。Everyone who comes first will get a present. 每个先来的人都可得到一份礼物。四、按照英语习惯，一个句子中若主要动词已经表明了所谈论动作的时间，那么与之相关的其他动词就不必再次指明同一时间，而往往使用一个比较简单的时态，如用一般现在时表示一般将来时等。比较：This discovery means that we will spend less on food. 这一发现意味着我们将减少在食品上的花费。This discovery will mean that we spend less on food. 这一发现意味着我们将减少在食品上的花费。五、在make sure(弄清楚)，make certain(弄清楚)，take care(注意，当心)，be careful(注意，当心)，mind(注意)，watch(注意)等后的that从句中通常也只用一般现在时表示将来意义。如：Take care that it does not occur again. 注意别再发生这样的事。We must take care that no one sees us. 我们必须注意别让人看见我们。Make sure you come back soon. 你要保证快点回来。Be careful that you don’t hurt her feelings. 当心别伤了她的感情。Watch that the baby doesn’t go near the heater. 注意别让宝宝接近加热器。Mind you read the examination questions carefully before you begin to answer them. 在答题前要注意仔细阅读考题。六、在it doesn’t matter, I don’t care, I don’t mind 等结构(以及类似结构)后的名词性从句也通常用一般现在时表示将来意义。如：It doesn’t matter where we go on holiday. 我们去哪儿度假都行。Does it matter who goes first? 谁先去这有关系吗？I don’t care whether we win or lose. 我不在乎我们是赢还是输。Don’t you care what happens to them? 难道你不关心他们出什么事了？七、在I hope , I bet, see (to it) 等后的宾语从句中通常用一般现在时表示将来意义，但有时也可直接用将来时态。如：I hope that you like [will like] it. 你希望你会喜欢它。I bet it rains [will rain] tomorrow. 我打赌明天会下雨。See (to it) that children don’t catch cold. 当心别让孩子感冒。I’ll see that nobody disturbs [will disturb] you. 我将确保没人打扰你。注意：see (to it) 后的that从句通常用一般现在时表将来，直接用将来的情形较少见。八、在as, than 引出的比较状语从句中可用一般现在时表示将来，也可直接用将来时态。如：We’ll get there as soon as you do [will]. 你一到，我们就到。We’ll probably drive faster than you do [will]. 我们开车很可能比你快。九、表示按规定、时间表、计划或安排要发生的动作。如：Are you on duty next weekend? 下周末你值班吗？The train leaves at 12:00. 火车12点开出。Where do we go now? 我们现在到哪里去?注意：在此用法中，句中通常有具体的时间状语。十、当主句为将来时态时，与之相关的by the time后接的从句要用一般现在时表示将来意义。如：By the time he comes, I will have left. 等他到时，我会已离开了。The film will have started by the time we get to the cinema．我们到电影院时电影会已经开始了。十一、表示现在将要宣布某事。如：I declare the meeting open. 我宣布会议开始。We learn Lesson Ten today. 今天我们学习第10课。十二、表示客观性很强的将来。如：Today is Friday, so tomorrow is Saturday. 今天是星期五，所以明天是星期六。My birthday is on a Sunday this year. 我今年的生日在星期天。注意：有时说话者对某一将来事实非常肯定，也用一般现在时。如：The future is bright. 前途是光明的。Final victory is ours. 最后的胜利是我们的。
