一般ask/asksaskedshall/will askshould/would ask进行am/is/are askingwas/were askingshall/will be askingshould/would be asking完成have/has askedhad askedshall/will have asked should/would have asked完成进行have/has been askinghad been askingshall/will have been askingshould/would have been asking2.现在完成时与一般过去时的区别：1)现在完成时表示过去发生的动作或存在的状况，但和现在有联系，强调的是对现在造成的影响或结果，它不能同表示过去的时间状语连用，汉译英时可加“已经”等词。简言之，利用过去，说明现在。如：I have already read the novel written by the world-famous writer.(已经看过，且了解这本书的内容)2)一般过去时只表示过去发生的动作或状态，和现在无关，它可和表示过去的时间状语连用，汉译英时可加“过”，“了”等词。简言之，仅谈过去，不关现在。如：I read the novel last month.(只说明上个月看了，不涉及现在是否记住)I lived in Beijing for ten years.（只说明在北京住过十年，与现在无关）3.现在完成时与现在完成进行时的区别：两者都可以表示“从过去开始一直持续到现在”，在含义上如着重表示动作的结果时，多用现在完成时，如着重表示动作一直在进行，即动作的延续性时，则多用现在完成进行时。一般不能用于进行时的动词也不能用于现在完成进行时。I have read that book.我读过那本书了。I have been reading that book all the morning.我早上一直在读那本书。4.一般将来时的表达方式：将来时用法例句1will/shall+动词原形表示将来发生的动作或存在的状态My sister will be ten next year.2be going to+动词原形含有“打算，计划，即将”做某事，或表示很有可能要发生某事Its going to clear up.Were going to have a party tonight.3be+doing 进行时表示将来go,come,start,move,leave,arrive 等词可用进行时表示按计划即将发生的动作He is moving to the south.Are they leaving for Europe?4be about to+动词原形表示安排或计划中的马上就要发生的动作，后面一般不跟时间状语I was about to leave when the bell rang.The meeting is about to close.5be to+动词原形表示按计划进行或征求对方意见Were to meet at the school gate at noon.6一般现在时表示将来时刻表上或日程安排上早就定好的事情，可用一般现在时表示将来The meeting starts at five oclock.The plane leaves at ten this evening.II.动词的被动语态：常用被动语态构成常用被动语态构成1一般现在时am/is/are asked6过去进行时was/were being asked2一般过去时was/were asked7现在完成时have/has been asked3一般将来时shall/will be asked8过去完成时had been asked4过去将来时should/would be asked9将来完成时will/would have been asked5现在进行时am/is/are being asked10含有情态动词的can/must/may be asked被动语态的否定式是在第一个助动词或情态动词后加 not，短语动词的被动态不可漏掉其中介副词。固定结构 begoing to,used to,have to,had better 变为被动态时，只需将其后的动词变为被动态。如：Trees should not be planted in summer./The boy was made fun of by his classmates.Newspapers used to be sent here by the little girl.汉语有一类句子不出现主语，在英语中一般可用被动结构表示。如：It is believed thatIt is generally considered thatIt is said thatIt is well known thatIt must be pointed out thatIt is supposed thatIt is reported thatIt must be admitted thatIt is hoped that下面主动形式常表示被动意义：如：The window wants/needs/requires repairing.The book is worth reading twice.The door wont shut./The play wont act.The clothes washes well./The book sells well.The dish tastes delicious./Water feels very cold.注意事项下面词或短语没有被动态：leave,enter,reach,become,benefit,cost,equal,contain,last,lack,fit,fail,have,appear,happen,occur,belong to,take place,break out,come about,agree with,keep up with,consist of,have on,lose heart 等等七情态动词七情态动词 I.情态动词基本用法：情态动词用法否定式疑问式与简答cancan not/cannot/cant docould能力（体力，智力，技能）允许或许可（口语中常用）可能性（表猜测，用于否定句或疑问句中）couldnt

为例。must+do(be)是推测现在存在的一般状态进行；must+be doing 推测可能正在进行的事情；must+have done 是推测可能已经发生过的事情。1.must“肯定，一定”语气强，只用于肯定句中。He must be a man from America./He must be talking with his friend./He must have already arrived there.2.may 和 might“也许”，后者语气弱，更没有把握。可用于肯定句和否定句。He may not be at home./They might have finished their task.3.can 和 could“可能”，could 表示可疑的可能性，不及 cant 语气强，用于肯定、否定、疑问句中。The weather in that city could be cold now.We could have walked there;it was so near.（推测某事本来可能发生，但实际上没有发生）Can he be in the office now?No,he cant be there,for I saw him in the library just now.(语气很强，常用于疑问句和否定句中)III.情态动词注意点：1.can 和 be able to:都可以表示能力。但 be able to 可以表达“某事终于成功”，而 can 无法表达此意。Be able to 有更多的时态。另外，两者不能重叠使用。2.used to 和 would:used to 表示过去常常做现在已经不再有的习惯，而 would 只表示过去的习惯或喜好，不涉及现在。3.need 和 dare 作情态动词和实义动词的区别：两者作情态动词时常用于否定句和疑问句。其形式为：neednt/darent do；Need/daredo?做实义动词时可用于肯定句，否定句和疑问句。其形式为：need(needs/needed)/dare(dares/dared)to do,dont(doesnt/didnt)need/dare to do八非谓语动词八非谓语动词I.非谓语动词的分类、意义及构成：构成非谓语形式时态和语态否定式复合结构特征和作用不定式to doto be doing to have doneto be doneto have been donefor sb.to do sth.具有名词，副词和形容词的作用在句中做主、宾、定、表和状语分词现在分词doinghaving donebeing donehaving
