形容词前面加be动词什么意思

形容词前面加be动词什么意思

做为一个句子中要有动词，be动词可分为：is are am以及他们的各种时态，通俗点将给一个句子:他很帅。若用中文直译则会变成：he very handsome
一看就知道是个病句，没有动词，所以在此句子中handsome作为形容词前面要加be动词，根据主语来选择，原句加入be动词后就为：he is very handsome。希望采纳，原创

就表示,是某某状态的意思 比如:good be good 就是说"某某东西是好的" 是要加的

例如：he is handsome boy .在这里的handsome是形容词跟在IS的后面做表语，形容词前加BE构成系表结构。

be [bi:] 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”是个特别动词；有些语言，如中文和马来文，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). 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. 2. Mary's new dresses are colourful. 3. I have been there before. 4. Mother is in the kitchen now. 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.“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.
