问题描述:

she must appear in a bright red dress.that's what she has to do后半句什么结构?怎么翻译?

她一定会穿着鲜红的裙子出现,那是她必须做的。
后半句包含了What引导的表语从句what she has to do她不得不做的事情

希望能帮到你,祝你成功。

她一定会穿着鲜红的裙子出现,那是她必须做的

that's what she has to do=that's the thing (that she has to do)
what=the thing (that ...) 意为:.的事/物.本身作先行词和引导词,具有双重功效.再如:
那就是我喜欢的(东西)
That's what I like.= That's the thing (that I like)
全句意为:她肯定穿着鲜艳的红衣服出场,那是她必须做的.
