英语中回答感谢、寻求帮助分别怎么说

一，With pleasure和my pleasure 的区别
(1)----Thank you for helping me.
----- It's my pleasure
(2)-------Would you please open the widow?
------With pleasure.
It's my pleasure是回答别人的感谢的，可译为“那是我应该做的，那是我的荣幸”
而whth pleasure是回答别人的请求的，可译为“好的，乐意效劳”。 第一句是谢谢的意思。 My
pleasure是帮忙后说的 With pleasure可以是帮忙前。
二， 感谢：
Thank you.
Thank you very much.
Thanks a lot.。
Thank you for your help.
It's very nice of you.您真好
I'm very grateful for you. 【grateful a.感激的，感谢的】
三，寻求帮助【ask for help】
would you piease do sth?【请问您可以。。。么】
May I ask you a question? 【我能问你个问题吗】
Please give me a hand. 【请帮我个忙】，
could you do me a favor【您能帮我一忙么】

回答感谢：You're welcome.
寻求帮助：Could you help me?&Can you help me?&I need your help,please.
my pleasure整个句子应为"It's my pleasure.”，通常用于当帮助别人而受到感谢时的情景对话，意为“做这些是我的荣幸”；with pleasure一般用于在别人请求自己帮忙做某事时的肯定回答，意为“我很乐意”。
