不能.因为在这里是“什么途径”的意思.
which和what的区别是:前者用于选择范围较小或较明确的场合,后者用于选择范围较大或不明确的场合.
which 的选择范围相对比较小或明确,所以其后一般不接else,但却常与表特定范围的of短语连用:
Which of the three girls is the oldest?这三个女孩中哪个年纪最大?
Which of the boys is the strongest?这些男孩当中,哪一个力气最大?
你还要点别的什么吗?
正:What else would you like?
误:Which else would you like?
四、口语中的用法区别
比较以下三组对话,注意体会它们的区别:
A:Who is he?他是谁?
B:He is Mary’s husband.他是玛丽的丈夫.
注:Who is he?的意思是要了解他的一些情况.
A:What is he?他是干什么的?
B:He is an English teacher.他是英语教师.
注:What is he?的意思是询问他的职业.
A:Which is he?哪位是他?
B:The one by the window.窗户边的那位.
注:Which is he?的意思是要在几个人中辨别要找的人.
