谈谈have作助动词用法

谈谈have作助动词用法 have在现代英语中是用得较多的动词之一。它除了用作实义动词(ordinary verb), 表示topssess (具有),to hold (保持),to experience (经验)等意义外,还大量用作助动词。现就其助动词用法作一简述: 一、帮助构成完成时和完成进行时的各种时态。例如: 1)完成时: He has finished his task. The sun had already set before we arrived at the railway station. He shall have written the article by then. 2) 完成进行时: I have been working as an interpreter for years. He told me that he had been waiting for me even since the morning. 二、帮助构成复合谓语(和不定式动词连用)。 1) have to的用法。具有语气动词的作用,表示必须履行的义务责任(obligation), 或表示客观情况的需要,或必然性,几乎同情态动词must具有同样的意义。例如: I have to go there = I must go there. If you want to catch the first train you have to leave at six. He sees very badly, he has to wear glasses all the time. The children have to play in the streets till their mothers get home from work. In my district there is no gas laid on; people have to use electricity for every thing. be to和have to在意义上是不相同的。试比较下面两个句子: We are to finish our work at five o'clock. We have to finish our work at fine o'clock. 第一句are to finish 表示预定计划;这是大家知道的。第二句“have to finish”表示“必须在什么时候完成”,不管我们愿不愿意。 2) had to的用法。表示在过去时间里客观环境所产生的责任、任务或必然性,可用作 must的过去形式。例如: The buses were all full:I had to get a taxi. She fell ill and had to leave early. I got lost and had to ask a police man the way, When I changed my job, I bad to move to another flat. In October the expedition siled, but it had to make its way against adverse winds. 3)have to, had to常在会话中单独使用,这时不定式动词可不提及,但仍可理解。例 如: Do you have to translate the whole text into Japanese? No, you don't have to. why do you always wear dark glasses? I have to (wear them). My eyes are very sensitive. I didn't want to stop but I had to (stop) as I needed petral (汽油)。 三、have + object + past participle 结构. 1 )可更为简洁地用来表示下列类型句子的说法。例如: I employed someonce to do something for me.

助动词引导的一般疑问句

PEP小学六年级英语Unit 4 助动词do引导的一般疑问句 瞿家湾中心学校李晶晶一、教材与学情分析 第四单元’I have a pen pal ‘Part B Let’s talk 部分出现了“Does he like ……”句型,即涉及到由助动词does引导的一般疑问句的用法,来讨论他人的爱好和住所等问题。但目前我班学生对第三人称和动词的第三人称单数形式都不了解,如果直接进入到由does引导的一般疑问句的讲解,会让学生无法形成知识的迁移,无法理解新知识。所以我选择以do引导的一般疑问句为切入点,让学生能了解一般疑问句。再在学习和掌握了动词的第三人称单数形式的基础上,自然过渡到does引导的一般疑问句的学习中去。 二、教学重难点 重点:能对由do 引导的一般疑问句,进行肯定和否定的回答。 难点:将陈述句改为由do引导的一般疑问句。 三、教学设计 1 导入:教师由日常课堂中用过的一般疑问句进行提问 (1) Are you ready? (2) Can you understand? (3)Do you know? 学生回答后,老师指出今日的新知识:do 引导的一般疑问句。并板书问句和答句。(并可以依据学生的课堂反应来请学生仿写句子) 2玩游戏:快速找一找

找出哪些句子是一般疑问句,并读一读,翻译 老师提问:(1)一般疑问句在翻译时有什么特点?回答时又有什么特点?(2)在读一般疑问句时,语调上该注意什么? 3 创设情景,在对话中感受和运用一般疑问句。 (1)Mike: What are you going to do ? Jim: I’m going to play football. Mike: Do you like it? Jim: Yes, I do. (2) Lucy: How do you come to school? Army: By bike. Do you come to school on foot? Lucy: No, I don’t. 对话训练:让学生运用已学句型和短语,在情景中练习一般疑问句。 4 造句并回答。 (1)Do you like drawing pictures? (2) Do you go to school by bike? 5对话练习:仿写句子并自编对话,进行练习。 6 将陈述句转化为一般疑问句 (1)教师呈现句子,引导学生观察,并总结出规律。 I like drawing pictures? Do you like drawing pictures? Yes, I do. I have comic books.

变一般疑问句详细讲解

一、如何变一般疑问句: 1. 首先找BE动词(am, is, are, was, were),把它提到句首。如果句中有some, 要改为any。 2. 如果没有BE动词,就找can,will, must, may等情态动词, 把它提到句首。如果句中有some, 要改为any。 3. 如果没有情态动词,就加do, does帮助构成疑问句。如果主语是单数第三人称,就用does 帮助构成疑问句,把它放到句首, 原来的动词改为原型。如果句中有some, 要改为any。 如果主语不是单数第三人称,就用do帮助构成疑问句, 把它放到句首,。原来的动词不变。如果句中有some, 要改为any。 4. 如果句子是一般过去时,要加did帮助构成疑问句 一般疑问句的基本用法及结构 一般疑问句用于对某一情况提出疑问,通常可用yes和no来回答,读时用升调。其基本结构是“be / have / 助动词+主语+谓语(表语)”: Is he interested in going?他有兴趣去吗? Have you ever been to Japan?你到过日本吗? Does she often have colds?她常常感冒吗? Did you ask her which to buy?你问没问她该买哪一个? 二、陈述句变一般疑问句的方法 1. 动词be的疑问式:动词be根据不同的时态和人称可以有am,is,are,was,were 等不同形式,可用作连系动词(表示“是”、“在”等)和助动词(用于构成进行时态和被动语态等),但不管何种情况,构成疑问式时,一律将动词be的适当形式置于句首:Am I right?我是对的吗?Are you feeling better today?你今天感到好些了吗? Was he late for school?他上学迟到了吗? 2. 动词have的疑问式:动词have根据不同的时态和人称可以有have,has,had等形式,可以用作实意动词和助动词,分以下情况讨论: ①用作实意动词表示状态,如表示拥有、患病或用于have to表示“必须”等,在构成构成式时可以直接将have,has,had置于句首,也可根据情况在句首使用do,does,did:Does he have [Has he] anything to say?他有什么话要说吗? Did you have [Had you] any friends then?他当时有朋友吗? ②用作实意动词表示动作,如表示“吃(=eat)”、“喝(=drink)”、“拿(=take)”、“收到(=receive)”、“度过(=spend)”等,构成疑问式时不能将have提前至句首,而应在句首使用do,does,did: Does he have breakfast at home?他在家吃早餐吗? Did you have a good time at the party?你在晚会上玩得高兴吗? ③用作助动词构成完成时态,其疑问式总是将have等置于句首: Have you finished your work?你的工作做完了吗? Has he left when you arrived?你到达时他已离开了吗? 3. 情态动词的疑问式:情态动词的疑问式通常是将情态动词置于句首: Can you speak English?你会说英语吗? Must I finish the work at once?我必须马上完成工作吗? 4. 实意动词的疑问式:一般实意动词的疑问式,通常应根据不同时态和人称在句首加助动词do,does,did等: Do you go to school every day?你每天都上学吗? Does the boy like dancing?这男孩喜欢唱歌吗?

He knows how to drive a car, doesn't he? 他知道如何开车,对吧? do 这个词(does是第三人称单数形式),大体上从两方面来讲。 1.作为行为动词,跟其他动词一样,如study, play等。他的意思是“做”等。如: We usually do our homework in the afternoon. He does his homework in the evening. 2.作为助动词,也就是帮助主要动词构成否定和疑问等。 We don't like bananas. Do you like apples? Does he like English? He doesn't like swimming 上面有一句He does his homework in the evening.要是变成否定句就成了这个样子: He doesn't do his homework in the evening. 这里加上了助动词doesn't,而原来的主动词does变成原形do了。 作为助动词的do和does是没有词义的,它们在句中的构成一般现在时的疑问句和否定句.

Have与 has的用法及区别

Have与has的用法及区别 have与has都是“有”的意思,但二者用法是有区别的. 在陈述句中,当主语是单数第三人称(he、she、it)时,句子的谓语是“有”时,用has;当主语是其他人称(I、you、we、they)时,句子的谓语是“有”时,用have. 例句: I \ You have an apple . We\They have some apples . He\She has a pen . 但是,在疑问句中,当主语是就单数第三人称提问或否定句时用助动词does 和does not (doesn't),然后把has 变成have 如果不是第三人称,助动词就是do ,否定式do not (don't).特殊疑问句回答照样,该是has 还是has 该是have 还是have 但是当一般疑问句以do或does开头的时候,只能回答do don’t 或者does doesn't 例句: Do you have a book yes ,I do /No ,I don't What does a cat have the cat has a , He doesn’t have any coffee. 就是第二种:have本身也可以作为助动词,(作为完成时里的助动词)本身无词义,和do 一样,has 就相当于does 在单三情况下用,主要用于构成各种时态、语态、语气以及否定和疑问结构.(那此时的have还是has就要看具体的人称而定)完成时态是have/had + done (过去分词的形式) I have finished my work, she has finished her work have you finished your work? Has she finished her work?在一般疑问句里回答直接用have/has yes,I have/ No ,I haven't Yes,she has/ No,she hasn't(因为这里have/has是助动词)
