1.Let me (do something)
如果想礼貌些，但仍然表现得十分亲密友好，那么就可以说“let me...”
Let me sit you up so you'll be more comfortable.
让我帮你坐起来，那样你会更舒服。
- That's a good question. Let me find out for you.
这是个好问题。我来帮解答。
2.Do you want me to/Do you want sth?
如果你对于对方接受帮助的意愿十分没有把握，那么直接问吧。
Do you want me to sing it for you?
你要我为你而唱吗？
在口语中，还可以省掉开头的“do”，
- You want to meet up after class and go over it?
你想不想下课后碰一下，我帮你重新过一遍？
3.Would you like me to/Would you like sth
和上一种表达类似，但更为正式些，可以对顾客使用，也可以是比较疏远的人。
Would you like me to throw them away?
想我帮你扔了吗？
4.I can (do something)
I can...也是一种礼貌的提供帮助的表达。比如商场里的店员对顾客说，
I think I can fix this for you.
我想我可以帮你修好。
5.I'd be happy to
这也是正式用法，常用于商务场合和专业人士间。
- I'd be happy schedule a time to meet and talk with you about it.
我很乐意安排时间和你会面探讨这个问题。
6.May I offer you(something)?
这是非常正式的提供帮助的表达方式，听起来有些浮夸。
May I offer you some refreshment?
我给你来点吃的怎样？
