关于助动词be的问题The children are playing in the field.这句里面的be动词are可以省略吗,为什么一定要用这个助动词,
当然是不可以省略的.
助动词是跟着时态走的.
这句句子是现在进行时,现在进行时的标准格式是,助动词be+动词的现在进行时.
如果你不要are,就不能用现在进行时,可改用一般现在时.the children play in the field.但是时态改了,意思也会略微改变.
建议看些简单的英语语法书,关于时态的.

不可以，因为这里边的are 是要和后边的playing 构成现在进行时，现在进行时的形式是be doing，是固定格式，所以不可以省略

不可以省略
句子要有主语和谓语,这两个不能省略.
这里的be 动词就是谓语

be动词的用法
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.
