  • 总算认识小学英语be动词用法总结

    be动词,意思和用法很多,一般的意思是:是,此种用法,有多种变化形式,另外,be动词还有成为的意思。下面是小学英语be动词用法总结,大家一起来看看吧! 小学英语be动词用法总结: 一、be 动词做助动词 助动词be 有两个基本用法,一是与谓语动词一起构成各种时态,二是构成被动语态。 “be + 现在分词组”成各种进行式时态。例如: Tony's maid is washing his new car. The children are playing in the field. Samuel was eating when I came in. We have been living here since 1959. This time next day they will be sitting in the cinema.

(助动词有两个:can be ) [疑问句] Can all the wonderful birds be found in our Bird Park? (移第一个can) [否定句] All the wonderful birds can not be found in our Bird Park. (在第一个can 后加not) [肯定句] I have been there before. (两个助动词:have, been ) [疑问句] Have you been there before? [否定句] I have not been there before. [肯定句] I shall be having my supper at six tomorrow evening. (两个助动词:shall, be ) [疑问句] Will you be having my supper at six tomorrow evening? [否定句] I shall not be having my supper at six tomorrow evening. 三、助动词be,无词义,辅助主要动词一起在句中作谓语动词。用法如下: 1. be+doing:构成进行时态,有现在和过去两种进行时态。如: The girls is reading and copying the new words now. Young Tom was always asking questions and trying out new ideas. 2. be+going to do,表示“打算或将要做某事”,be有现在和过去两种形式。如: We are going to plant trees in the park. I didn’t know if she was going to come here. 3. be+to do,表示“按计划安排将要做某事”。如: The new shop is not to be opened till next Monday. One night an angel came to Mary and told her that she was to have this special boy. 四、there be there be句式为:there be+主语部分+状语部分,表示“某处存在某物”,be常用现在时,过去时和将来时等。如: Oh, cool! And there are many things to see. There is even a deer park in Sanya. There are about 80 pyramids in Egypt. Will there be a football match in your school next week? 五、实义be 可以将be视为实义动词,因为它具有实际的词义,如“成为;做;发生;举行;逗留;到达”等。如:His daughter wants to be a doctor for animals in her birthday party will be at half past six this has been in China for morethan two years, but he has not yet been to Yichang. 动词object的用法: 可用及物或不及物动词,使用时注意以下几点: 1. 用作不及物动词时,其基本义为“反对”,若需带宾语,须后接介词 to。如: I object to all this noise. 我不喜欢这些嘈杂的声音。 Do you object to Sunday work? 你反对星期日上班吗? 由于其中的to为介词,所以后接动词时要用动名词。如: Do you object to working on Sundays? 你反对星期日上班吗? I really object to being charged for parking. 我非常反对收停车费。 若表示反对某人做某事,object to后可接带有逻辑主语的动名,注意不要想当然地使用object sb to do sth。如: He strongly objected to your saying that. 他强烈反对你这样讲话。 I object to him [his] smoking in restaurants. 我反对他在饭店里吸烟。 2. 用作及物动词时,意为“反对说”“反对的理由是”,其后通常只接that从句作宾语,而不接名词或代词作宾语。如: Bill objected that it would take longer. 比尔反对说,这会花更长时间。 Mother objected that Jimmy was too weak to take up the job. 母亲反对说,吉米身体虚弱,不可承担那份工作。 用作及物动词的object也可用于引出直接引语,这与后接宾语从句本质上是一样的(因为宾语从句可视为由直接引语转化来的间接引语)。如: “But he’s too young,” I objected. “但是他太年轻了,”我反对说。 3. 根据上面的说明可知,object用作及物或不及物动词时,不仅用法不一样,而且意思也不一样:不及物时表示“反对”,及物时表示“反对的理由是”“提出……作为反对的理由”。比较以下例子: 我父母反对我与她结婚。 误:My parents objected that I married her. 正:My parents objected to my marrying her. 他反对被当作小孩子看待。 误:He objected that he was treated like a child. 正:He objected to being treated like a child. 他说我不够仔细而提出反对。 误:He objected to my not being careful enough. 正:He objected that I was not careful enough. 动词oblige的用法: 1. 表示“迫使”时,注意以下用法: (1) 其后通常不直接跟不定式,但可接不定式的复合结构。如: The law obliges parents to send their children to school. 法律迫使父母送孩子上学。 不过,在现代英语中该结构通常用于被动形式。如: You are obliged by law to pay taxes. 按照法律规定,你必须纳税。 They were obliged to sell their house in order to pay their debts. 他们被迫卖房还债。 (2) 在许多情况下,obliged具有形容词的特点,有时其被迫意味较弱,常可译为“有必要”“有责任”“应该”等。如: I felt obliged to ask them to dinner. 我觉得有必要请他们请饭。 2. 表示“帮忙”“效劳”时,通常指根据需要或要求而做某事,注意以下用法: (1) 可以用于不及物动词。如: We’d be happy to oblige. 我们乐于效劳。 Will you oblige by filling in this form? 劳驾填一下这张表好吗? (2) 用作及物动词时,总是以受益者(指人)作宾语,使用时注意以下搭配和用法: ①用于oblige sb by doing sth,表示通过做某事而帮助某人或按某人的要求做某事。如: Please oblige me by keeping quiet during the lecture. 演讲期间请保持安静。 Could you oblige me by posting the letter? 劳驾请帮我把这封信寄了好吗? ②用于oblige sb with sth,表示用某物来帮助某人或按某人的要求提供某物。如: Could you oblige me with 10 dollars? 借给我10美元好吗? Would you be willing to oblige us with some information? 你愿为我们提供一些信息吗? (3) 修饰oblige有个非常典型的副词,就是duly,表示“正如期望地效劳或帮忙”。如: The fans were looking for another goal and Owen duly obliged. 球迷们正期待另一粒进球时,欧文一如期望地进球了。 3. 表示“感激”时,在现代英语中,只用于被动语态be obliged(事实上已变为系表结构),主要用于以下两个结构: (1) 用于I (We) would be obliged if…,用于正式场合请人帮忙,其意为“如果……我(我们)将非常感激”。如: I would be obliged if you could read it to us. 你若能读给我们听,我将非常感激。 其中的if从句有时可换成不定式。如: I would be obliged therefore to receive your instructions on this matter. 如果在这个问题上能收到你的指导,我们将非常感激。 (2) 用于(I’m / We’re) much obliged,意为“(我 / 我们)非常感谢”;表示感谢某人,其后可接介词to;表示因某事而感谢,后接介词for。如: I’m obliged to you for your good opinion. 感谢你的宝贵意见。 I’m very much obliged to you for telling me. 我非常感激你告诉了我。 I shall be much obliged to you for an early answer. 尽早赐复,不胜感激。 (3) 注意不要混淆obliged与obliging的用法,后者的意思是“愿意帮忙的”“乐于助人的”“热情的”。如: He is always very obliging. 他总是乐于助人。 The official to whom we applied for a permit was most obliging. 我们向他申请许可证的那位官员非常热情。 动词occur的用法: 1. 表示“发生”“出现”,是不及物动词,所以不能带宾语,也不能用于被动语态。如: 事故(地震)是什么时候发生的? 误:When was the accident (earthquake) occurred? 正:When did the accident (earthquake) occur? 每页都有两三个错误。 误:Two or three mistakes are occurred in every page. 正:Two or three mistakes occur in every page. 2. 表示某想法出现在某人脑海中或被某人想到,通常与介词 to连用。如: A good idea occurred to me. 我想起了个好主意。 His name just did not occur to my memory. 我就是想不起他的名字。 在以上用法中,若主语为从句或不定式,则在句首使用形式主语 it, 而把真正的主语放在后面。如: It occurred to me that he might be lying. 我忽然想起他可能是在说谎。 It never occurred to me to insure the house. 我从来也没想到过去给房子投保。 Didn’t it occur to you to phone them about it? 难道你就没有想到给他们打个电话? 3. 有时用于there be句式中替代动词be。如: Not long after this, there occurred a sudden revolution. 此后不久,突然爆发了革命。 In March 1770, there occurred what became known as the Boston Massacre. 在1770年3月爆发了人们熟悉知的波士顿大屠杀。
