Question

单句改错

No matter who leaves the room last ought to turn off the lights．

Answer 1

答案：No matter who→Whoever
解析：

no matter who只能引导让步状语从句，引导主语从句时要用whoever。whoever＝anyone/the person who。 　　故答案为No matter who→Whoever 　　no matter who/what/when/where等引导的从句只能作状语，而whoever, whatever, whenever, wherever等引导的从句，既可以作状语，也可以作主语和宾语。
