关于非谓语动词问题

The study argues that the type of action needed against passive smoking should be similar to that being take against illegal drugs and AIDS.请问可不可以把 needed换成needing和为什么还有 needed在此句子里作为什么成分？

Answer 1

一般一个句子的结构是由“主语+谓语+宾语"构成的。
在“The study argues that the type of action needed against passive smoking should be similar to that being take against illegal drugs and AIDS.”这句话中，先找出谓语"should be similar to",所以“The study argues that the type of action needed against passive smoking ”就是主语，“that being take against illegal drugs and AIDS”就是宾语。因为一个句子中只能有一个谓语（动词），所以当主语中出现动词“need",它就要使用非谓语动词的形式。主语中“action”是被需要，要用非谓语动词的被动语态“needed"。
如果非谓语动词修饰的名词是动作的发出者的话，就要用“ing”的形式，如“the cat jumping"中猫是主动跳的，而不是被跳，所以，要用"jumping"。

Answer 2

不能用needing啊
正确是语序是 action is needed 省略了is 所以是the action needed
needed作后置定语

Answer 3

needed不可以换成needing。 needed 做定语 修饰action
