當你要求他人幫你做什么或當他人要求你幫他做什么時，聽上去很有禮貌的語意是你成功的一部分。現在講講一般情況下你可以怎么說：
Ask someone to do something for you 請求他人幫你做什么：
"Could you please open the window for me?"
"Would you mind opening the window for me?"
"Can you open the window for me?"

Tips:

Could and can 后面的動詞不跟to.
Would you mind后面跟動詞原形加-ing.
Ask if you can do something 詢問你可不可以這樣做：
"May I use your computer?"
"Could I buy some drink for you?"
"Do you mind if I read loudly?"
"Would you mind if I turn on the radio?"

Remember 記著:
Could比can聽起來更客氣些.
Do you mind if...后面跟現在時態的動詞；Would you mind if...跟的是過去時態的動詞.
當你用"Do you mind if..." or "Would you mind if..." 時，后面不要再跟"Please"了。這樣的語義已經很客氣了。不要再畫蛇添足了。
