be的用法口诀有哪些-必赢56net在线登录

be的用法口诀有哪些 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。

be动词的用法:be (be/is/are/am/was/were) vi 现在时 I am, you are, he is, we are, you are, they are (缩略式 I"m, you"re, he"s, we"re, you"re, they"re), (否定缩略式 I"m not, isn"t, aren"t), 过去时 I was, you were, he was, we were, you were, they were (过去时否定缩略式 wasn"t, weren"t), 过去分词been, 现在分词being 英语的“be”是个特殊动词;有些语言,如马来文等,并没有“be”这样的 动词。

“Be”除了原形的“be”之外,还有另外七种形式:am, is, are, been, being, was, were. 在句子中,“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb) 例句对照 【当主动词时,“be”在性质上属于接系动词(The Linking Verb), 后面要有 名词、形容词、地方副词或短语作补足语(The Complement)。例如:
1. The man is a science teacher. 这个男子是一位科学教师 2. Mary"s new dresses are colourful. 玛丽的新衣服色彩鲜艳3. I have been there before. 我以前去过那里 4. My mother is watching TV in the room. 母亲现在在客厅看电视 【这四个都是陈述句,可以变成疑问句,方法简单,把主语和“be”或助动 词对换位置即可:
5. Is the man a science teacher 6. Are Mary"s new dresses colourful 7. Have I been there before 8. Is mother in the kitchen now 【当“be”要在祈使句中出现时,它必须借重助动词“do”或“don"t”之助,如:
9. Don"t be silly! 10. Do be obedient! 11. Don"t be a fool! 【“Be”有两种缩写法,如下:
12. He"s not...../He isn"t.... 13. You"re not...../You aren"t... 【但“am + not”的缩写法只有一个:
14. I"m not. 有人用“ain"t”, 但这并不是标准英语。

谈过了“be”作主动词的功能,现在看看“be”作助动词时,有些什么用 法:
【1.】“Be + 现在分词”以组成进行式时态(Continuous Tenses),如:
15. Tony"s maid is washing his new car.16. The children are playing in the field. 17. Samuel was eating when I came in. 18. We have been living here since 1959. 【2.】“情态动词+Be + 过去分词”以组成被动语态(The Passive Voice),如:
19. Her money in the drawer was stolen. 20. A number of good jobs are taken up byforeigners. 21. David studied in Taiwan but has been trained as a language lecturer in America. 22. Can all the wonderful birds be found in our Bird Park 23. The disobedient boy was told to stand out- side the classroom. 24. Steps are being taken to reduce traffic con- gestion during peak hours. 25. Dishonest students will be immediately dealt with.推荐访问:口诀 用法 有哪些 be的用法口诀有哪些 小学be动词用法口诀 be原型的用法
