It is worth trying.这里的worth是介词吗

It is worth trying.这里的worth是介词吗

你好,有两种理解
介词或者形容词
我一直理解是介词+doing
但是现在查字典发现还有一种形容词理解
把worth看做少数必须有补语才能成立的形容词,那么doing其实做的事形容词补语.
并不是只有介词才可以加动名词的 就像like doing sth 一样
请问like不是动词么?你在这里把疑似介词或者形容词的worth与动词比较有意义么?我可以很明确的说在这个句子It is worth trying.这句话中worth符合一个介词的所有要素,完全可以作为介词理解.
希望对你有帮助
