有关英语宾语从句陈述语序

牢记一条。按主谓宾的顺序排列的是陈述语序。which do you like best 陈述是 you like which best 。其中which做like宾语。用do做助动词,放在like前面提问。what were they doing 陈述是what they were doing或者they were doing what。 were doing 这种有be动词形式的疑问句就是把be提前。单独看which is your favorite book这个句子是问句啊。换成what也还是问句。但是如果放在句子中做从句的话。which此时就做了代词,成为了后面从句的主语。句子主语在谓语is之前,那当然就是陈述语序啊。eg：I don't know what is your favorite book。我不知道你最喜欢的是什么书。
