为什么ABC都不行,
I want to know _________.

I want to know _________.
A. whom is she looking after B. whom she is looking
C. whom is she looking D. whom she is looking after
为什么D不行呢?是不是句末不能加介词?解释答案就是D. whom she is looking after

1。_________ he comes, I'll tell you。主句用将来时从句用现在时，典型的条件状语从句，
只能用if，意思是如果。I don't know _________ he will come tomorrow。可用if或whether，意思是是否。
2。答案就是D吧，句末能加介词，而且其他选项是错的
A没有用陈述语序，BC都少了介词。...

第一题的第一个空可以用if，也可以用whether，第二个空只能用if，所以只能选D
第二题 look after是照顾的意思。

前一个空whether和if都可以选，引导的是宾语从句，后一个是条件状语从句只能if引导，如果他来，我将告诉他
后一个题目我觉得是选D啊

第一题D，whether和if都可以引导宾语从句，表示“是否”，题中意为我不知道他是否会来。从第一空来说，两者都是可以的。但第二空是说“如果他来，我会告诉你”，空处只能填“如果”，所以结合起来只能选D。
第二题D。题意为我想知道她正在照顾谁，此为考查宾语从句。LOOK AFTER是一固定搭配，后面介词不可省。B项肯定是错误的...
