精品文档精品文档情态动词表推测用法总结（一）情态动词表推测的三种句式能用于表推测的情态动词：must,can,could,will,would,may,might,should,ought to 1.在肯定句中一般用must(一定)，may（可能），might/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）It is cold in the room.They must have turned off the heating.屋里很冷，他们肯定把暖气关了。2.否定句中用cant/couldnt(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。（2）He may not/might not know the scientist.他也许不认识那位科学家。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。Couldn t 比 can t 语气弱一些。（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）She must/may/might/could walk miles and miles among the hills without meeting anyone.她一定/可能/也许会在山里一连走好几英里而遇不到一个人。2.对目前或一般情况的推测，用“情态动词+be”或“情态动词+动词原形”。（1）He cant(couldnt)/may(might)not be at home at this time.这个时候他不可能/可能不在家。3.对正在发生动作的推测，“情态动词+be doing”（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。4.对过去情况的推测，用“情态动词+have+过去分词”。（1）It must/may/might/could have rained last night.The ground is wet.地湿了，昨晚肯定/可能/也许下雨了。（2）The door was locked.He can(could)not/may(might)not have been at home.门锁着，他不可能/可能不在家。（3）Can/Could he have gotten the book？难道他找到书了吗？补充强调：推测的句型特点（对某一次的推测句型有两部分：语气和时态）（1）语气部分：（以下情态动词语气由强至弱）肯定句：must、may、might（=could）否定句：cant（=couldn t）、maynt、mightn t疑问句：can、could（语气更加委婉不确定）（2）时态部分：be 表示对现在的推测have done 表示对过去的推测be doing 表示对正在进行的推测语气部分写在前时态部分写在后，组合在一起就是推测（三）几组表推测的情态动词用法“情态动词完成时”是历年高考的热点，在做此类练习时，既需要掌握这一结构的基本用法，又应该仔细体会题干所提供的语言信息，准确理解语言环境和说话人的含义，尤其要注意题干中时态给予的暗示。.must have done 表示对已经发生的事情的推测，意为“一定，想必”,句子中表示的是一种肯定的推测。这种结构一般只用于肯定句，其否定形式是cant（couldn t）have done，表示“不可能，肯定不会”。例如：He didn t hear the phone.He must have been asleep.他没有听到电话响，他肯定是已经睡着了。一、单项选择1 John_ come to see us

ZM2H4L6Q4T7精品文档精品文档14.公园里现在肯定有一些老人正在散步。There _ some old people taking a walk in the park now.15.别玩小刀，你可能会伤到自己的。Don t play with the knife.You _ when，while，as 引导 时间状语从句 的区别When 1.表示“当 时候”，“当 之后”之意(1)从句中的动词无论是延续性动词，还是短暂性动词都可以用when 引导从句，主从句的动作可以前后，或同时发生。使用as,while,是主从句的动作必须同时发生，并且从句必须是延续性动词，Sorry，I was out when you called me （call 为短暂性动词）对不起，你打电话时我刚好外出了。Strike while the iron is hot （is 为延续性动词，表示一种持续的状态）趁热打铁。The students took notes as they listened （listen 为延续性动词）学生们边听课边做笔记。(2)从句中的动词是延续性动词，可以用while 或 as替代 when。My father is cooking while/when/as my mother is reading newspapers.?2.对两个同时进行的动作或状态进行对比时，多用while，亦可用as/when。While she was making a phone call,I was writing aletter.?3.当主句、从句动作同时进行，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用as。这时，“一边 ，一边”之意。The little girls sang as they went.The students took notes as they listened to the teacher.4.表示“随着”指时间的推移时，只能用as。As time went by,the days became colder and colder.As Christmas are coming nearer,the children got excited.As my grandfather is getting old,his memory is getting poorer.总结：表示当 时候，当 之后之意，多用when；表示主从句正在进行的动作或状态的对比时多用while；while 还可以用作对比”而”，如：My mother likes doing sports;while my father likes watching them 表示一边 一边 ；只能用as；表示随着 含义时，只能用as。Because,since,as,for 表原因的区别because,as,for,since这几个词都是表示“原因”的连词，语气由强至弱依次为：because since as for;其中 because,since,as均为从属连词，引导原因状语从句；而for 是并列连词，引导并列句。1.because表示直接原因，它所指的原因通常是听话人所不知道的，其语气最强。常用来回答why 的提问，一般放于主句之后，也可以单独存在。例如：(1)I stayed at home because it rained.因为下雨我呆在家里。(2)Because Lingling was ill,she didnt come to school.玲玲因病，没有上学。(3)Why is she absent?她为什么缺席？Because she is sick.因为她病了。此外，在强调句型中，只能用 because。例如：(4)It was because I missed the early bus that I was late for school.我上学迟到是因为我没有赶上早班汽车。2.since 侧重主句，从句表示显然的或已为人所知的理由，常译为“因为”、“既然”，语气比because稍弱，通常置于句首，表示一种含有勉强语气的原因。例如：(1)Since he asks you,youll tell him why.他既然问你，那就告诉他为什么吧。(2)Since everyone is here,lets start.既然大家都到齐了，我们就出发吧！(3)Since I understood very little Japanese,I couldnt follow the conversation.我日语懂得不多，因而听不懂对话。3.as是常用词，它表示的“原因”是双方已知的事实或显而易见的原因，或者理由不是很重要，含义与since相同，但语气更弱，没有since 正式，常译为“由于，鉴于”。从句说明原因，主句说明结果，主从并重。例如：(1)We all like her as she is kind.我们都喜欢她，因为她善良。(2)As I had a cold,I was absent from school.因为我感冒了，所以没去上课。(3)As Xiaowang was not ready,we went without him.由于小王没有准备好，我们只好不带他去了。4.for 用作连词时，与because相似，但它所表示的原因往往提供上文未交待过的情况。for 不表示直接原因，表明附加或推断的理由，因此 for 被看作等立连词，它所引导的分句只能放在句子后部(或单独成为一个句子)，并且文档编码:CH6C3G1N8W7 HB1P1A10H4X9 ZM2H4L6Q4T7文档编码:CH6C3G1N8W7 HB1P1A10H4X9

have rained,for the ground is wet.(从“地面潮湿”作出“下过雨”的推测，但地湿并不一定是下雨所致,for不可以换为because。)(3)The ground is wet because it has rained.(“下雨”是“地上潮湿”的直接原因。)前后两个分句间有一定的因果关系时(有时很难区分是直接原因，还是推测性原因)，for 与 because可以互换使用。例如：(4)I could not go,for/because I was ill.我没能去，是因为我病了。(5)He felt no fear,for/because he was a brave boy.他没有害怕，因为他是个勇敢的男孩。or 和 and 用法区别1.并列 结构中，or 通常用于 否定句，and 用于 肯定句。但有时and 也可用于 否定句。请注意其不同特点：There is no air or water in the moon.There is no air and no water on the moon.在否 定中 并列结构用or 连接，但含有两个否定词的句子实 际被看作是肯定结构，因此要用and。2.or 用于连 接并列的单词、词组、短语或句子,表示 或者 的意思。如:We can visit the World Park or travel around the world.我们可以参观 世界公园,或者周游全世界。3.or 用在 选择疑问句 中,灵活译为 还是。如:Is that an apple or an orange?那是 苹果 还是 桔子?4.or 用于 否定句 中,代替 and,表示 和的意思。如:I dont like bread,rice or porridge.我不喜欢 面包、米饭 和粥。5.or 用于连 接两个并列的句子,表示 否则,要不然 的意思。如:Hurry up,or youll be late.快点,否则你要迟到啦。but，however，though 区别but 是连词，连接两个 并列句，中间用逗号隔开，表示转折如：I wanted to buy a book,but I dont have enough money.though 是副词，但在句中的成分相当于连 词。引导从句，不能与 but 连用，可以放句首或者句中。意思是尽管如：Though it is so hot I have to go outside.I have to go outside though it is so hot.however 也是副词，剧中成分相当于连 词。可以放在句首或句中，后面一定要用逗号。表转折。放句首时，与前面的句子是转折的连接。放句首时，前后用逗号隔开,如：I wanted to buy a book,however,I do not have enough money 1,Its going to rain.Youd better take an umbrella _ you may get wet.A.or B.and C.but 2,Diana isnt here,_ leave a message on her desk.A.or B.so
