Question

What is worth doing is worth doing well

What is worth doing is worth doing well这个句子是主语从句，还是表语从句?
根据什么划分？

Answer 1

句子应该这样分析：What is worth doing 是主语从句。is是系动词，worth doing well 是表语。

为什么不能把句子
从第一个worth 后面断开？后面是表语从句呢？

谢谢老师

追答

语法虽能符合：doing 主语，is 系动词，worth doing well。但它的意思：（做是值得做好。）不合逻辑。

再者前面部分的语法也讲不过去。What is worth这变成一个疑问句了：（什么值得？）

不管什么事情，只要有一点值得做，就应该把它做好。
