He needs cleaning his room first.病句改错
need 后用动名词或不定式作宾语在意思上是有区别的.
当表示“主语（行为者）需要做某事”时,要用 one needs to do sth.
当表示“主语（行为对象）需要被做”时,要用 something needs doing 或者 something needs to be done
本句中的主语是行为者,意思是“他首先需要打扫他的房间”,因此应该改为 He needs to clean his room first.
如果把主语改为打扫的对象 his room,表述“他的房间首先需要被打扫”,可以有两种说法：
用动名词作宾语：His room needs cleaning first
用不定式的被动语态作宾语：His room needs to be cleaned first.
你好！
