肯定回答：Yes,I would./Yes,I would mind doing sth.或Yes,I do./yes,I mind doing sth.否定回答：No,I wouldn't./No,I wouldn't mind doing sth.
would的用法一种表示征求许可的表达
Would it be OKif……
一种非正式的征求同意的表达
还可以说成Would it be alright if……
Would it be alright if i did this tomorrow?
Would it be OKif ，would it be alright if 这两种表达之后的动词要用虚拟语气，过去式，如果你用现在时，也是可以的，只是听起来不是那么正式
would it be alright if i do this tomorrow?
如果你想更礼貌一些，可以试试这么表达吧
would i be able to
would I be able to talk to you this things?
当然还有一些其他的表达方法，需要灵活运用，根据自己所面对的情况而定，如，熟悉的人或是不熟悉的人，你想要给对方留下一个什么样的印象：
Is it OKif i leave late?
can he sit here?
Do you mind if I sit here?
Can I help you?
但是如果要想正式或礼貌一些，不妨试试这种问法
Could I have that?
Could I see you？
Could you give that to me?
这一次听起来有些礼貌了，但是任何时候想要表示礼貌都要记得加上 please
不管什么时候征求许可，加please都不会错。
