can you tell why they are doing for哪里错了
问题描述：
can you tell why they are doing for哪里错了
答
why该为what。
其实是个宾语从句。
转变成陈述语句就是“ can you tell me they are doing for what？”
答
tell 接双宾语，现只有一个宾语从句，故再加一个宾语，如 me （tell后）
答
Can you tell me why they are doing that?
或者： Can you tell me what they are doing that for?
do后面也应该跟宾语的
答
can you tell why they are doing for
why =what for
或者去掉for 或者把why 改成what就行了。
知识在于点滴积累，更在于不懈努力。
祝你学习进步，更上一层楼！
