I don't know when he will come. I can not wait here any more. when he comes, would you please ask him to call me?
意思是:我不知道什么时候他将要来,我不能再等了,当他来的时候,雀吵你能告诉他给我打电话吗?
第一个他将要来,因为“我”不知道,核耐所以用将来时,是宾语从句。第二个,当他来的时候,可以直接用一般现在时,就是他来了的意思,是条件状语从句,顷氏侍主句将来时,从句一般现在时。
will come(不知道睁御洞他什么时悉枯候来), comes(当拆指他来到.....)
第三个空应该没有吧? 就是 When he comes,would you please ask him to call me?
I don't know when he will come. I can not wait here any more. when he comes, would you please ask him to call me?
will come\ comes
宾语从句will come
条件状语从句comes
1.will come, 2.comes 1宾语从句用陈述句的形式2宾语从句,主渣蔽句现在时从句用相应的现如磨州在时,由于he是三单游正,用comes
