What a lovely present! It is worthy ___all my life.
A.of keeping B.to keep C.being keep D.to kept
答案是B,可是老师教我们的是be worthy to be done,麻烦解释一下为什么,顺便把worth,worthy的用法告诉我,谢谢!

应该是worthy to be kept吧
用法:
be worth sth./ be worth doing sth.主动形式表被动意义
be worthy to be done/ be worthy of being done
例如:the book is worth reading/ worthy of beingread/ worthy to be read.
另外:It is worthwhile to do sth./It is worthwhile doing sth.

be worthy to be done
worth of ...
而worth一般后面接ing形式

不定式后面是真正主语，it是形式主语。
这题是考语法的，不是句型的。
