扩展资料：
（1）在现代英语中，在 be worth 前使用形式主语 it 被认为是合习惯的。如：
It isn’t worth repairing the car. 这辆汽车不值得修了。
但是，若不用形式主语 it 而直接用动名词作主语则是错误的，如：
误：Repairing the car is worth.
（2）有关 be worthy 的搭配习惯
be worthy 后不能直接跟名词、代词或动名词，若要接，应借助介词of。如：
Their efforts are worthy of your support. 他们的努力应得到你的支持。
（3）与 be worth 后只接动名词不接不定式不同，be worthy 后不接动名词，而接不定式（若该不定式要表示被动意义，则应用被动形式）。如：
This suggestion is worthy to be considered. 这个建议值得考虑。
（4）若要在 be worthy 后接动名词，与后接名词时的情形一样，应借助介词 of，且该动名词若要表示被动意义，要用被动形式。如：
This suggestion is worthy of being considered 〔=to be considered〕. 这个建议值得考虑。
（5）有关 be worthwhile 的搭配习惯
（1） be worthwhile 后接动名词或不定式均可。如：
It is worthwhile buying the dictionary. 这本词典值得买。（其中的 worthwhile 也可换成 worth）
