看一下being的用法
Forty minutes's break only being allowed at noon.
总搞不懂BE动词的用法,这里为什么用BEING?

这只是一短语,不是句子.所以开头不能大写,后面别用句号.
only being allowed 是现在分词的被动语态作后置定语,修饰break.
意为:"仅在中午被允许的40分钟休息"
对了,应为：forty minutes',你多了个s．

首先是被允许，是被动时态所以用BE+过去分词。这里后面的句子做状语
所以加ING

因为Forty minutes's 中的's已经是谓语动词了,所以不能使用be
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...

因为Forty minutes's 中的's已经是谓语动词了,所以不能使用be
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.
从上面例子看，“be”这动词外貌平凡，但内涵丰厚。如果没有“be”，补足语的桥梁断了。如果没有“be”,何来进行式时态和被动语态？缺了这几样重要的句式，英语还像英语吗？

收起

being用作形容前面的break，前面的forty minute's break中的's不是动词，是介词，意思是40分钟的休息。全句意思是“只允许在中午休息的40分钟”，是名词结构，里面没有动词，不是一句话。
