英文情境對話問題

1.展覽會結束,點樣有禮貌同參觀展覽既客人講?並叫佢地離開展覽會?
Good afternoon everybody, it is the closing time for the exhibition and we would like to ask if anyone could leave accordingly as scheduled. Thank you.
2.同客人講不可以在此拍照片,該點樣有禮貌說?
Would you please to take pictures somewhere else because no one will be allowed here.
3.客人問我問題,我不識答,我要點樣先可以同客人?並叫佢去問果邊既同事?
Please wait a minute and I'll ask one of my colleague to attend you.

TomingBB 乃神經刀，不必對他太認真。Most probably he does not know what he is talking about. TomingBB is not much different from the guy who always asks questions on present perfect tense.

Just a suggestion:

3. I am afraid I am not in a position to help you. Would you mind asking my colleague over there?

"發問者希望得到一些較得體和婉轉的說法"
非常認同知足常樂 ( 知識長 ), 我有同感

回答者001 三句都無禮貌, 還談什麼委婉說法 (Euphemism ) ?
You must be joking!

回答者002 客氣很多!

回答者：yip****** 本來是回答者002
因為上一位回答者TomingBB 自己刪除回答
所以 yip****** 變了回答者 001
希望不要誤會

發問者希望得到一些較得體和婉轉的說法，所以或者不要說得那麼直接。

例如 (3)，你可以說：

I am sorry that I am not very sure for this issue, may I introduce my colleague over there who may be able to solve your problem?

又例如 (2)，你可以說：

I am afraid it is not appropriate to take photos here, thank you for your understanding.
