问对方是乘什么交通工具来的,"你是怎么来的?"怎么说

How did you get here, by a taxi, or?

What means of transportation do you get?这是比较正式的说法了。
means of transportation交通设施
The train is a safe means of transportation.
火车是一种安全的交通工具。

如果是比较熟的人，就用how就行了
How did you get here?

How did you get here？

应该是“how did you come here?”吧……
“how do you come here?”会不会被误解为“你来这儿干嘛？！”

用how就行啊 真是

how do you come here?
