我究竟怎么了555
系动词Be(am, is, are)的用法一、请记住以下口诀:我用am,你用are,is连着他,她,它; 单数名词用is,复数名词全用are。 变疑问,往前提,句末问号莫丢弃。 变否定,更容易,be后not莫忘记。 疑问否定任你变,句首大写莫迟疑。 二、Be动词在一般过去时中的变化:1.am 和is在一般过去时中变为was。(was not = wasn’t)2.are在一般过去时中变为were。(were not = weren’t)3.带有was或were的句子,其否定、疑问的变化和am,is, are一样,即否定句在was或were后加not,一般疑问句把was或were调到句首。情态动词有can (could), may (might), must, have to, shall (should, will (would), need (needed), ought to等。 情态动词无人称和数的变化;不能单独使用,必须与其后的动词原形构成谓语 一、 can, (could 过去式)1) 表示能力(体力、知识、技能)。 Can you lift this heavy box?(体力) Mary can speak three languages.(知识) Can you skate?(技能) Can只有一般现在时和一般过去式; 2) 表示请求和允许。 -----Can I go now? ----- Yes, you can. / No, you can’t. 3) 表示客观可能性(客观原因形成的能力)。 They’ve changed the timetable, so we can go by bus instead.This hall can hold 500 people at least. 4) 表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。 Can this be true? This can’t be done by him. How can this be true? 二、 may, might 1) 表示请求和允许。might比 may语气更委婉,而不是过去式。否定回答时可用can’t 或mustn’t,表示“不可以,禁止”。 ----Might/ May I smoke in this room? ---- No, you mustn’t. ---- May/Might I take this book out of the room? ---- Yes, you can. (No, you can’t / mustn’t. ) 用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。 2)用于祈使句,表示祝愿。 May you succeed! 3) 表示推测、可能性(不用于疑问句)。 might不是过去式,它所表示的可能性比may小。 1.He may /might be very busy now. 2.Your mother may /might not know the truth. 三、 must, have to 1) 表示必须、必要。 You must come in time. 在回答引出的问句时,如果是否定的,不能用mustn’t(禁止,不准),而用needn’t, don’t have to(不必). ---- Must we hand in our exercise books today? ---- Yes, you must. ---- No, you don’t have to / you needn’t. 2) must是说话人的主观看法, 而have to则强调客观需要。Must只有一般现在时, have to 有更多的时态形式。 1. he play isn’t interesting, I really must go now. 2. I had to work when I was your age. 3) 表示推测、可能性(只用于肯定的陈述句) 1. You’re Tom’s good friend, so you must know what he likes best. 2. Your mother must be waiting for you now. 四、 shall,1) shall 用于第一人称,征求对方的意见。 What shall we do this evening? 2) shall 用于第二、三人称,表示说话人给对方的命令、警告、允诺或威胁。 1. You shall fail if you don’t work hard.(警告) 2. He shall have the book when I finish it.(允诺) 3. He shall be punished.(威胁) 五、 should,1) should,表示 应该 劝告、建议和命令。 1. I should help her because she is in trouble. 1. You should go to class right away. 2. Should I open the window? 3) 表示推测 Should(客观推测) , must (主观推测)。 1. He must be home by now. (断定他已到家) 2. He should be home by now.(不太肯定) 一般现在时的构成:(1) be动词:主语+be(am,is,are)+其它。如:I am a boy.我是一个男孩。(2) 行为动词:主语+行为动词(+其它)。如:We study English.我们学习英语。当主语为第三人称单数(he, she,it)时,要在动词后加"-s"或"-es"。如:Mary likes Chinese.玛丽喜欢汉语。‘ 一般现在时的变化:1. be动词的变化。(1)否定句:主语+ be + not +其它。如:He is not a worker.他不是工人。(2)一般疑问句:Be +主语+其它 如:-Are you a student?
