How come you are so interested in the environment?
问题描述:
How come you are so interested in the environment?
这个是课文里的句子,不是说疑问句后面的be动词要提前吗?为什么不是how come are you so interested in the envirronment?
答
这里的come是系动词,相当天be动词或become,
come link-v.成为、变为、变得.
you are so interested in the environment是省略了that的表语从句.
how come 后面直接加表语从句(不用倒装),表达一种语气:愤怒或惊讶.美口语
how come :怎么会(是).…(这样),这是美式英语口语的固定搭配.
