Please explain

[Anonymous]

Dear teacher,

A)
Please explain for me what the following sentences mean.

1)Excuse me. I couldn't help overhearing.(Is that sentence the same with this one: Excuse me. I couldn't hear any at all?)
2) ... unless, that is, you have to do gambit up your sleeve.

B)Are they correct?
1)Don't you remeber me? I am the one who introduced the web site englishpage.com to you.
2)Where part of Vietnam are you in?
3)What are you? = What's your jobb?

Thanks a lot

A) Please explain for me what the following sentences mean.

1)Excuse me. I couldn't help overhearing.(Is that sentence the same as this one: Excuse me. I couldn't hear any at all?)
-- No. To overhear something is to hear something that wasn't directed to you. Thus this means,
- Excuse me. Even though I wasn't really trying to listen to your conversation, I heard what you said (and I want to comment about it).

2) ... unless, that is, you have to do gambit up your sleeve.
-- I Can't tell what this is supposed to mean. Here a gambit probably means a trick that is designed to fool someone and help you win or succeed.

B)Are they correct?
1)Don't you remember me? I am the one who introduced the web site englishpage.com to you. [Ok with spelling correction.]
2)Where part of Vietnam are you in? [No. Say
- What part of Vietnam are you in?
or maybe, - Where in Vietnam are you?
The word "in" is puzzling but not necessarily wrong; the question implies that you can communicate with someone but not know where that person is located. This probably means that this is part of an e-mail note.]
3)What are you? = What's your job?
-- "What are you?" is not commonly used with this meaning. "What do you do (for a living)?" is much more common. You might use your sentence immediately following a declaration of your profession,
- I'm a lawyer; what are you?
-- Here it would probably be understood correctly, but it would still be unusual.
