情态动词
被动语态牢记一点,
+be+V （ p.p ） be 加动词过去分词。 分析句中主和谓， 承受者作主语即被动。 短语动词不可忘介、 副词。 另有不及物动词， 只有主动无被动。 还要注意其时态, 与主动语态全相同。 不用被动语态的情况 （即多数的瞬间动词）： 亡） ,disaPPear （消失），end （vi. 结束），fail, happen, last, lie, asleep, keep silenee, lose heart, take place. 比较： rise, fall, happen 1）不及物动词或动词短语无被动语态 app ear, die （死
rema in, sit, sp read, break out, come true, fall After the fire, very little rema ined of my house.
是不及物动词；raise, seat 是及物动词。 （错）The accident was happened last week. （对）The accident happened last week.
要想正确地使用被动语态，就须注意哪些动词是及物的， 哪些是不及物的。特别是一词 多义的动词往往有两种用法。解决这一问题唯有在学习过程中多留意积累。 2） 不能用于被动语态的及物动词或动词短语 ：
wish, cost, notice, watch agree with, arrive at suffer from, happen to, take part in, walk in to, bel ong to the lock. 3） 系动词无被动语态（“ keep ”除外）： grow, look, remain, seem, smell, sound, stay, taste, turn It sounds good. 4） 带同源宾语的及物动词，反身代词，相互代词， live, life She dreamed a bad dream last ni ght. 5） 当宾语是不定式时，很少用于被动语态。 （对）She likes to swim.
（错）To swim is liked by her. sta nd fit, have, hold, marry, own, / in, shake hands with, succeed in, This key just fits appear, be become, fall, feel, get, 不能用于被动语态：die, death, dream, 有些动词可以带双宾语。在这种情况下, 有些动词可以带双宾语 在用于被动结构时， 主动结构中的间接宾语变为主语时，直接宾语仍然保留在谓语后面；直接宾语变为主语时， 间接宾语前通常加上介词 for/to, etc. 。 即: S+V+0+D3 I0+ be done +D3 DO be done + prep. + 10 We often hear him play guitar Heis often heard
td
1]
play guitar.
T It is often heard from him to play guitar.
新被动语态
Get+过去分词也可以构成被动语态，用这种结构的句子侧重于动作的结果而不是动作本
怎样把主动语态改成被动语态? 把主动语态改为被动语态非常简单，
1. 将主动语态的宾语作被动语态的主
语；
2. 谓语动词变为“be+及物动词的过去分词”，并通过be 的变化来表达出不同的时态;
3. 主动语态的主语变为介词“ by ”的宾语，组成介词短语放在被动结构中的谓语动词 之后。（有时
“ by ”的短语可以省略）；
例: 1. Bruce writes a letter every week. week.

初中英语情态动词用法详解 【情态动词知识梳理】 情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。 考点一：can，may，must等情态动词在陈述句中的用法： 1. can的用法： （1）.表示能力、许可、可能性。表示能力时一般译为“能、会”，即有种能力，尤其是生来具备的能力，此时may和must均不可代替它。如：She can swim fast, but I can’t . 她能游得很快，但我不能。I can see with my eyes.我用眼睛看。 （2）.表示许可，常在口语中。如：You can use my dictionary. 你可以用我的字典。（3）.表示推测，意为“可能”，常用于否定句和疑问句中，此时can’t译为“不可能”。如：Can the news be true?这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们老师吗？—No, it can’t be our teacher. He is on a visit to the Great Wal l.不可能。咱们老师正在游览长城呢。 【例题】—I think Miss Gao must be in the library. She said she would go there.—No. She __be there, I have just been there. 【解析】根据下文“我刚去过那儿”可知，应为“不可能”，can’t表示推测[答案] 2. could的用法： （1）.can的过去式，意为“能、会”，表示过去的能力。如：He could write poems when he was 10. 他十岁时就会写诗。 （2）. could在疑问句中，表示委婉的语气，此时could没有过去式的意思。如:Could you do me 你能帮我个忙吗？—Could I use your pen?我能用一下你的钢笔吗?—Yes, you can.可以。（注意回答） 3. may的用法： （1）.表示请求、许可，比can正式，如：May I borrow your bike?我可以借你的自行车吗？You may go home now.现在你可以回家了。 【例题】—_______ I borrow your MP3?—Sure . Here you are. A. May B.Should C.Must D.
初中英语情态动词的基本用法讲解 1. can （could） 1）表示能力，could 主要指过去时间。 Two eyes can see more than one. 两只眼比一只眼看得清。 Could the girl read before she went to school? 这女孩上学前能识字吗？ 2）表示可能（理论上或是逻辑判断上）。 The temperature can fall to —60 °C , that is 60 °C below freezing. 气温可降至一60 C，也就是零下60 C。 He can't （couldn't） have enough money for a new car. 他不可能有足够的钱买新车。 You mustn't smoke while you're walking around in the wood. You could start a fire. 在林子里走时勿吸烟，那样可能会引起火灾。 3）表示允许。 Can I have a look at your new pen? 我可以看一看你的新钢笔吗？ He asked whether he could take the book out of the reading-room. 他问他可不可以把书带出阅览室。 4）表惊异、怀疑、不相信等态度。主要用于否定句、疑问句或感叹句中。 Where can （could） they have gone to? 他们会去哪儿了呢？ He can't （couldn't） be over sixty. 他不可能超过六十岁。 How can you be so careless? 你怎么这么粗心？ 5）比较委婉客气地提出问题或陈述看法。 Can （Could） you lend me a hand? 帮我一把好吗？ I' m afraid we couldn 't give you an answer today. 恐怕我们今天不能给你答复。 2. may （might） 1）表允许，might 可以指过去时间，也可指现在时间，语气更委婉。 You may take whatever you like. 你喜欢什么就拿什么。 He told me that I might smoke in the room. 他告诉我可以在房间里抽烟。 May （Might） I ask for a photo of your baby? 我可以要一张你宝宝的照片吗？ 在回答以may引起的问句时，多避免用这个词，而用其它方式，如Yes, please. / Certainly. / Please don' t ./ You' d better not. / No, you mustn ' t.等，以免显得太严峻或不客气。 2）表可能（事实上）。可以指过去时间，也可以指现在时间，但语气更加不肯定。 He may be at home. 他可能在家。 She may not know about it. 她可能不知道这件事。 He was afraid they might not agree with him. 他担心他们可能不同意他的意见。 They might be having a meeting, but I ' m not sure. 他们有可能在开会，不过我不肯定。 3. must 1）表示义务。意为“必须” （主观意志）。 We must do everything step by step. 我们一切都必须循序渐进地做。 You mustn' t talk to her like that. 你不可能那样对她说话。 --Must we hand in our exercise —books now? 我们现在就要交练习本吗？ --No, you needn' t. / No, you don' t have to. 不必。（这种情况下，一般不用mustn' t）2）表示揣测。意为“想必、准是、一定”等，只用于肯定句。
情态动词must用法详解 (1) 表示“必须” 此时可用于肯定句、否定句或疑问句，用于否定句时，mustn’t的意思是“一定不要”“不能”，而不表示“不必”。如： Water must be pure if it is to be drunk. 水如供饮用必须净化。 Must I finish the work tonight? 我必须今晚完成这项工作吗? Adverbs mustn’t be put between the verb and the object. 副词不能放在动词和宾语之间。 must主要表示现在或将来，但在间接引语中也可表过去(=had to)。如： She asked her boss if she must (had to) work overtime. 她请示上司她是否要加班。 对于must开头的一般疑问句，若作否定回答，可以用needn’t，不能用mustn’t。如：“Must I clean all the rooms?” “No, you needn’t.” “这些房间我都得清扫吗?”“不必。” (2) 表示推测 意为“准是”“一定是”，通常只用于肯定句。若用于否定句或疑问句，则用can 代之。如： That can’t be the only way. There must be other ways of solving the problem. 那不可能是解决问题的唯一办法，肯定有另外的办法。 Jane’s light is on. She must be at home. She can’t be out. 简的房间里开着灯。她一定在家，不会出去的。 若要谈论过去或完成的情况，必须用“must+have+过去分词”。如： You must have mistaken my intention. 你一定是误会了我的意图。 She must have been very young when she got married. 她结婚时一定很年轻。 He must have come this way; here are his footprints. 他一定是走这条路来的，这里还有他的脚印呢。 They must have finished their homework, for they are playing happily on the playground. 他们一定是写完作业了，他们在操场上玩得多开心呢。 (3) 表示“偏偏” 有时must可表示某事发生得不早不迟，就在某个当紧的时候，多指某些不受欢迎的事情的发生。如： The car must break down just we were starting our holidays. 我们刚刚开始休假，汽车偏偏坏了。 Must you worry her with questions, just when she is busy cooking dinner? 她正忙着做饭你干吗偏偏问她问题? Just when I was busy, the neighbor must come and chatter. 正当我忙碌的时候，邻居偏偏过来聊天。 有时还可指主观上的偏执或固执，常可译为“偏”“偏要”。如： After I gave her my advice，she must go and do the opposite. 在我给她出主意之后她偏要反着干。 Must you make so much noise? 你就非得弄出这么大的声音吗？ (4) must 与have to 的区别 两者都表示“必须”，但must 侧重于说话者的主观看法，认为有必要或有义务去做某事；have to 则重于客观需要，含有“不得不”“被迫”之意。如： Everyone must keep the law. 人人都要守法。 The last train has gone. We’ll have to walk home. 最后一班车已经开了，我们得走回家了。

初三英语情态动词must 的用法总结教学案例 初三英语情态动词“must”强化训练教学设计 一、教学设计 （一）学情分析（Learning situation analysis） 进入初三我所接手的班级的情况比较复，初一、初二两年频繁调换英语教师，学生的知识不够系统化，学习方法、做题思路等都不够成熟，且基础普遍较差。英语复习课是巩固和发展知识、技能的重要课型.它的作用,就是帮助学生重温已学的知识和技能,使记忆中的痕迹得到强化,并对已获得的知识加以整理、归纳、概括,使知识条理化、系统化.因此教师必须注意引导学生多动脑、多动手、多参加课堂活动。复习课如果上得不好，往往会变成旧课的重复，或者是新课的“再版”。这样不仅不能发挥复习课的作用，而且会使学生因乏味而降低学习兴趣。此教学案例的教学对象是初三学生，整体英语水平较低，且自主学习能力有限，自主学习的习惯还没有形成；大部分学生的基础不牢固，学习习惯较差，学习兴趣不大。 （二）课标与教材分析（Curriculum and teaching material analysis） 按照《国家英语课程标准》要求，现行的英语课堂教学模式应该是以学生为主体的课堂，鼓励学生以参与的方式掌握应用英语语言知识的能力。英语教学目标中是这样描述的：“基础教育阶段英语课程的总体目标是培养学生的综合语言运用能力。综合语言运用能力的形成是建立在学生语言技能、语言知识、情感态度、学习策略和文化意识等素养整体发展的基础上。”语言知识和语言技能是综合语言运用能力的基础，文化意识是得体运用语言的保证，情感态度是影响学生学习和发展的重要因素，而学习策略则是提高学习效率、发展自主学习能力的关键。因此，这五个方面共同促进综合语言使用能力的形成。 （三）教学目标与要点分析（The teaching goal and key points of analysis） 1. The teaching goal (教学目标)： 1）Knowledge objectives (知识目标)：To master modal verb “must”. To understand some special cases. 2）Ability to target (能力目标)：To use ”can” freely and correctly. 3）Emotional attitude goal (情感态度目标)：To enjoy communicating in English. 2.
