① Who is this?
在许多外国人眼中，“Who is this?”是最简洁和最合理的表达之一，而且不含冒犯他人之意，是个礼貌性表达。
A: Hey, is Natalie there?
A: 嗨，娜塔莉在吗？
B: Yeah, who is this？
B: 在的，您是哪位？
② Who is it?
当然了，“Who is it?”也是老外最常用的口语化表达之一，也比较礼貌。
“Hello, who is it?”，he picked up the telephone and said.
“你好，哪位？”，他拿起电话说道。
③ May I ask who is calling?
“我能请问下是哪位呢？”，这可能是目前最为安全和礼貌的表达了，在专业的场景下（比如说公司前台）使用频率很高。
A: Hello, is Boris there?
A: 您好，请问鲍里斯在吗？
B: Sorry, he is being abroad on business. May I ask who is calling?
B: 抱歉，他现正在出差。请问你是？
④ Would you mind telling who is calling?
“介意告诉我你是谁吗？”，可以说是一个非常正式的表达了。
Ben is not there. Would you mind telling who is calling?
本不在。 介意告诉我你是谁吗？
who is it一般用在跟对方直接说话的场合，但是往往是看不到对方的时候，比如对敲门的人
who's this的两种回答分别是“It's me”和“It's+人名”。这一话通常是用于人们电话沟通时，此时接听电话的一方如果不知道是谁打来的电话，通常会用“Who's this”来询问对方的名次，而对方则会用“It's me”或“It's+人名”告知别人自己的姓名和身份

10. who is that girl和who girl that is？
Who girl that is?这句特殊疑问句是错误的。特殊疑问句通常是由特殊疑问词加上一般疑问句构成。而who这个特殊疑问词之后的girl that is明显是错误的。
那个女孩是谁？正确的问法是Who is that girl? is that girl是一个标准的一般疑问句位于特殊疑问词后面。
