请问是to do 还是doing?it is worth for us learning/to learn his quality上面那句和这句的意思一样吗?it is worth learning his quality
请问是to do 还是doing?
it is worth for us learning/to learn his quality
上面那句和这句的意思一样吗?
it is worth learning his quality
请问是to do 还是doing?it is worth for us learning/to learn his quality上面那句和这句的意思一样吗?it is worth learning his quality
这两个句子都有问题.
1、如果 it 是形式主语,可以用 it is worth while doing sth.或 it is worth whileto do sth.其中动名词短语或不定式短语是主语,is worth while（值得花时间）是谓语,即“做某事值得花时间”.如：
It is worth while visiting [to visit] the place.这地方值得参观.
It is worth while to discuss [discussing] the problem.这个问题值得讨论一下.
有时候,动名词或不定式都可以带有自己的逻辑主语,但是形式不同——
带有逻辑主语的动名词复合结构是 one’s doing sth.
带有逻辑主语的不定式复合结构是 for sb.to do sth.
因此,你所说的这个句子用既可以用动名词或也可以用不定式,但是必须在 is worth 后跟名词 while（一段时间）,而且各自的逻辑主语也是不同的——
It is worthwhile our learning his quality.（直译：我们了解她的品质这件事是值得的）
It is worthwhile for us to learn his quality.（直译：我们去了解他的品质这种行为是值得的）
2、如果主语是具体名词（也可以用 it 指代）,那么就可以用 something(或 it) is worthdoing；其中的something 是 doing 的逻辑宾语,也就是说动名词后不能再带宾语.如：
The book is worth reading.这本书值得一读.
The film is worth seeing.这部电影值得一看
所以,你提到的第二个句子应该改为——
His quality isworth learning.他的品质值得了解.
3、以上两种表达方式在意思上差不多,只不过强调的重点不同.
第一种句型 it is worth while doing (to do)sth 的主语是 doing (to do) sth,强调的是“动名词所表示的这种事情或不定式所表示这种行为” 是值得花时间的.】
第二种句型 something is worth doing 的主语是something.强调的是 “某事物” 值得被做.
