Will you, Would you 和 Would you mind 的分別？怎解？

Will you --->問他人將來的行動
e.g. Will you go shopping tomorrow? 你明天會去購物嗎?
Would you --->有禮貌地問人有咩需要
e.g. Would you like to have a cup of tea? 你要一杯茶嗎?
Would you mind --->你介意......嗎?
e.g. Would you mind giving me your telephone number? 你介意給我你的電話號碼嗎?

冇 Shall you, 只有 Shall I 同 Shall we
e.g. Shall we talk?
Shall I help you?

Should you 只有以下這種情況出現
Should you go to the foreign country, I will miss you so much.
( = If you should go to the foreign country, I will miss you so much. )
如果你真的去了外國, 我會很掛念你
should 強調 go to the foreign country 的機會很小
