i know who he is.类似这句的句子.是什么结构啊? I know that he who hesitates is lost. 请帮忙分析一下句子结构. I do not know who is he? i know who he is?i know who is he?哪个对 I don't know who he's talking about.这里的who是什么用法 may i know who is he in this sentence?翻译成中文是什么? i just feel that i lose someone but i don't know who is he 这 我不知道他是谁的英文翻译是i don't know who is he 还是i don't know who he is Who is ( Do you know ( ) yes,he i I don't know ( )(him).Who is ( )(he)? What he said was ok.句子结构划分 I know want it is The old man thi do you know who he is 和who do you think is he?的区别
