1L的例子貌似不是宾语从句.which 可以引导名词性从句,它与waht一样要在从句中充当成分.但是要根据具体意思来使用.what 与which 的一般区别为 当指代没有范围的事物时用what,指代有范围的事物时用which. 例如：I don't know what you want to choose I don't know which one you want to choose from the three jobs —“Why did you go to the wrong class,Mr.Wang” —“Well,I forget _______ I was supposed to go to.” A.which the room B.which room C.what was the room D.what room was it 此题选B
