what在从句当中的用法
请问这两个句子那个对?1.i want to know what is the difference between a and b.2.i want to know what the difference between a and b is.

第二句对通常,what is XXX 是疑问句,what XXX is 是陈述句注：what 也可换成同系列的who,where,why,when,how例：Why are you still watching TV instead of doing homework?可转换成 I don't know why you are still...
