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)
