What grade is Andy in 与Which grade is Andy in 的区别是什么?
答
你好，通常来说，用Which来提问，有选择的意味，Which grade is Andy in ,Grade A , Grade B or Grade C? 或者，在提问之前，大家已经知道有一共哪几种grade可以选（There are three kinds of grade--Grade A , Grade B and Grade C），接着就可以用Which来提问. 而用What 来提问，就比较随意，不知道目前具体有什么样的grade。
答
what grade is Andy in? 安迪在几年级?这是通常的用法.
Which grade is Andy in ,grade 1 or grade 2? which 是选择疑问句,后面要加上选项.
