动词的时态语态.doc

动词的时态与语态的综合运用确定正确的时态 1.根据时间状语确定时态.时间状语与时态有着密切的关系.a. I _ (write) now. b. I _(lose) my pen yesterday.c. We _ (study) English for two years. 2.根据上下文来确定时态 有些句子没有明显的时间状语,又不能用时态呼应规则来对照,这时就可以根据上下文内容来判断时间关系,确定正确时态. A.Where are the twins? B.They _ (go) to visit Uncle Wang. 3.根据主从句的关系来确定时态. 4.根据语言习惯来确定时态 *1.come,go,leave 等趋向性动词的进行时可用来表示即将发生的动作.*2.永恒的真理和客观存在的状态用一般现在时.*3.祈使句中,或在情态动词,助动词后,谓语动词用原形Dont _ (read)in the sun , will you? Youd better _ (stay)at home since its raining outside. 注意所填动词的语态 Today both basketball and volleyball _(play) in many countries. 确定动词的形式 1. be busy,what about等后用动词的-ing 形式. 2.在介词后一般应用动词的-ing 形式. 3.在 keep,enjoy,finish,mind 等动词后采用动词的-ing 形式. 4.在动词 decide,hope,wish,hate 等动词后应用动词不定式作宾语,而在ask, tell,want,teach 之后则用动词不定式的复合结构,即 “ask sb. to do sth.”的形式 5.在see,hear,watch,make,let等后面作宾语补足语的动词不定式应省略动词不定式符号“ to”, 但在被动句中, 应添上to. 6.在 Its time(for sb.)to do sth. Its kind/nice/good of sb. to do sth.It takes sb. some time to do sth. 的句型中, 动词不定式短语作句子真正的主语. 7.疑问代词/副词 (why 除外) + to do sth. 结构,可在句中作主语, 表语和宾语. 练习题： 1.The Great Green Wall will stop the wind from _(blow) the earth away. 2.Mr Smith kept on _ (ask) the players to remember-TEAMWORK 3.Alice didnt hear what the teacher said just now,so she doesnt know how _ (do) the problem. 4.The policeman asked the old granny to put down her heavy box and let him _ (carry) it for her.

Ive left Shanghai for three days.() Ive been away from Shanghai for three days.( ).I left Shanghai three days ago. ( ) It is /has been three days since I left Shanghai.( ) 2.初中英语课本中常见终止性动词有:leave, go, come, arrive, begin, buy, borrow, die, join, become等.终止性动词要表示持续时, 可用以下方法: .将时间状语改为时间段 + ago,句中谓语动词用一般过去时. eg.我弟弟参军两年了.

(表示目前人在这里) gone to 去某地了,说话时某人已离开此地,在去某地的途中或已在某地, eg. She has gone to Shanghai。 (表示现在她人不在这里) been in/at 逗留在某地(已经一段时间).常和for ten days,since I came here等连用. eg. She has been in Shanghai since she moved there. 4.现在完成时和一般过去时的区别现在完成时所表明的是过去发生的动作对现在的影响,强调的是现在的情况,不可以和表示过去的时间状语yesterday,in 1991,three days ago last time,last night等连用一般过去时表明的是过去发生的事实,和现在不发生关系. 5.现在完成时中的 for 与 sincefor + 时间段 与延续性动词的现在完成时连用 since + 时间点/从句I have kept the library book for a week.= I have kept the library book since a week ago. 6. It is /has been +一段时间 + since 从句.自从某事发生已有一段时间了. eg.

By the end of last term,we had learned a thousand English words. He had finished his homework before his father came back last night. 2.表示过去某个时间之前发生的动作或状态, 一直延续到这一过去时刻,或还将继续下去. eg. When I got to know him, he had worked there for twenty years.(注意) 否定式 had not = hadnt 时态的呼应 1.主句中谓语动词如果是现在时或将来时,从句中的谓语动词可以用任何所需要的时态, he wants to speak to the headmaster. He said that he wont be free tomorrow. he came last night. 2.主句中的谓语动词如果是过去时态,从句中的谓语动词一般情况下要用过去时态的某种形式. He said that he was working hard on his Chinese.he had a very good journey home. he hadnt bought the present yet.he would stop in Moscow on the way. 3.如果从句所述内容是客观真理,则谓语动词总是用一般现在时,而不受主句中谓语动词时态的影响. eg.

The window was broken yesterday. Is English taught in your school? 2.强调或突出动作的承受者,此时如想同时指出动作的执行者,可用“by +动作执行者(宾格)来表示. eg.The red dress was made by her mother. The letter must be written by me. 注 意点： 1.只有及物动词能构成被动语态, 不及物动词不能构成被动语态. 2.某些不及物动词与介词.副词搭配构成短语动词,带有宾语时,则有了动作的承受者,这时应把它们看作一个整体,变为被动语态,不能丢掉其中的介词,常用的有look after,take care of,cut down, laugh at,talk about,turn on等 eg.Catherine always takes care of the little girl.The little girl is always taken care of by Carherine. 3.有些动词短语本身即是被动语态的形式, 不要再加by 短语,常用的有 be covered with be surprised at be interested in be worried about be made of/from be known to 4.某些动词形式是主动语态,但含有被动的意思. eg. This dictionary sells well. This kind of car drives fast. The woolen sweater costs $ 88. 5.主动语态与被动语态的相互变化关系 主动句: 主语 + 谓语 + 宾语(动作执行者) (动作承受者)被动句: 主语 +谓语动词的被动形式+ by + 动作执行者 (动作承受者) 1）主动句如何变为被动句 a.找到动作的承受者(常为主动句的宾语)作被动句的主语.b.找到谓语变为be + 过去分词的结构.c.找到动作的执行者(常为主动句的主语)作 by 的宾语.若不必指出动作的执行者,可省去 by 短语. d.确定be动词的时态.数. 例如: She makes the beautiful kites.The beautiful kites are made by her. (被动句) 2）被动句如何变为主动句. a.找到动作的执行者(常为被动句的宾语)作主动句的主语.b.找到be+过去分词结构还原为及物动词原形.c.找到动作的承受者(常为被动句的主语)作主动句的宾语.d.确定及物动词的时态.数(注意)在以上转换中,代词作主语用主格, 代词作宾语用宾格. 6.主动语态中有些动词如:make,see,listen, watch,feel后常跟不带to的动词不定式作宾语补足语,变为被动语态要带上to He made the boy work for him. The boy was made to work for him. 7.主动语态中若有双宾语,变为被动语态时, 通常把指人的间接宾语变为被动语态的主语. His uncle gave him a dictionary yesterday.He was given a dictionary by his uncle yesterday. 练习题: 把下列句子变为被动句: 1.They asked me to come a little later. I _ _ to come a little later. 2.Women often talk about food and clothes. Food and clothes _ often _ about by women. 3.Do they make this kind of truck in Nanjing? _this kind of truck _ in Nanjing? 4.We must clean our teeth twice a day.

Quite a few tall buildings _ _ in their hometown last year. 3. You must not put the bike there. The bike _ _ _there. 4. Can you see the stars in the daytime? Can the stars _ _in the daytime? 句子（三）四、祈使句：表示请求、命令、建议或劝告等的句子叫祈使句，主语you通常省略。1、祈使句的肯定形式：一般以动词原形开头。 Open the door, please. 2、祈使句的否定形式：在句首谓语动词前加Dont。 Dont be late for class. 3、说话对象是第一人称和第三人称时，表示建议做某事。 Let me/us Let him/her/them eg. Lets go to school. 注意： 1)祈使句 and/or 简单句是常用句型 祈使句 + and + 简单句 表示“如果，就” 祈使句 + or + 简单句 表示“否则” eg. 1.Go down the street,and youll see a hospital. 2.Be quick,or well be late. 2)在祈使句后面，常常附加一个问句，使语气更加委婉。 eg.Tell me about it,will you/wont you? Dont tell anyone,will you? Lets go to school,shall we? Let us go out to play for a while,will you? 练习题 1)_ on the thin ice. Its dangerous. A.Dont skate B.Dont skating C.Skate D.Not skate 2)Lets fly the kite on the playground, _ _?（附加问句） 3)Please turn down the radio a bit, _ _?（附加问句） 句子的分类:由句子结构来讲，可分为三类简单一、简单句：由一个主语(或并列主语)和一个谓语（或并列谓语）构成的句子。 eg. We cleaned the windows and tidied the room. 二、并列句：由并列连词and, but,so,or,for等把两个或两个以上的简单句连起来的句子。 eg. 1)I come from China and he comes from Japan. 2)Hurry up,or youll miss the train. 3)He looked for it everywhere, but he couldnt find it. 4)She didnt know the answer to the question,so she asked the teacher. 5)Hes interested in music while John is interested in sports. 三、复合句 A.宾语从句：宾语从句在复合句中作主句的宾语，引导宾语从句的关联词有that, if/whether, what, who, whose, which, why, when, where, how等。 1、连接词 1)由连接词that引导陈述句，在口语中that常省略。 eg. He said that he would like to see the headmaster. 2)由连接词whether/if引导一般疑问句，whether和if 常可互换，但下列场合一般用whether. 介词后的宾语从句：Im thinking of whether hell come. 与or not连用：I dont know whether I should go or not. 3)由连接代词what,who(whom,whose)which或连接副词when,where,why,how引导特殊疑问句。 eg. Do you know who/whom she is waiting for? 2、语序：不管宾语从句是陈述句、一般疑问句或特殊疑问句，都要用陈述句语序，也就是说主谓次序不能颠倒。连接词主谓结构 (1).Bill wanted to know who did this. (2).I dont know whats the matter with Bob? (3).I dont know whats wrong with them? 3、时态：一般说来，主从句时态要统一。如果主句是一般现在时，从句可根据需要用其它任何时态；如果主句是一般过去时，从句应该用相应的过去时态范畴（也就是用一般过去时，过去进行时，过去将来时，过去完成时）。 eg.Lily wanted to know whether her grandma liked the handbag. I asked the teacher where we would have the meeting. Could
