在外企工作的中层Mary说，所谓的“夹杂体”说话在职场中并不新鲜，“我当年还是一个小职员的时候，有同事是香港人，讲话就是这样的，因为他们的普通话能力有限，有些词不知道用普通话怎么表达，长此以往，就经常在普通话中夹杂一些英文单词。

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.. isn\'t....
13. You\'re not.. 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.
这些生词同学们可以记忆下来，用到自己的产品介绍当中去。
194. What happened to you? 你怎么了？
One possible reason is that dust can affect the breathing system and people may be more open to infection. Another theory is that people may stay in their homes more during the dry season, making it easier to catch meningitis from others. The epidemics usually stop when the summer rainy season begins.
纽约真是个好地方。给你些照片看好吗?
such gustatory exotica as killer bee honey and fresh catnip sauce.
e.g. When it comes to computers, Tim is the expert.
