在电话中问:"你是谁"用英语怎么说
----Who's that speaking? ----May I know who's speaking now? (更客气一些) 我非常吃惊，这一句话居然有不同答案！
在电话中问:"你是谁"用英语怎么说 what's that ?
Who is calling? 哪位啊? May I asking for whom I speaking with? 我能问一下您的姓名吗? 从简从繁,请您自己斟酌.
“请问你/您是哪位呀？”， Who's that(speaking / calling)? / Who's speaking? / May I ask who's (that) calling?等。如果有迹象表明对打电话人心有把握，就直来直去——Is that Jim (speaking)?。
Who am i speaking to? Who is this? May i know who is calling? This is Sam speaking. I am Sam.
---who is that/it?你是哪位？ ---(this/it is) Tom (speaking).我是汤姆。 这是英语的习惯。 This is...表示:这边是某某某(接电话的这一边) I'm...表示:我是某某某,一般用在自我介绍当中. 所以,在打电话时,常用This is...而不是用I'm...
