beworth的用法，他后面跟被动语态吗还有be

Be worth用法:
1.be worth doing 值得做 在这里doing主动表示被动含义 例如The book is worth reading.
2.be worth to be done 这是worth后面加不定式 要变成不定式的被动语态
3.be worth of being done
以上三种意思一样 后两种是被动语态
不要看上面的答案 我跟语法书讲的一样 不信你去查书 上面的答案 有的简直是胡说 什么be worth to do sth啊

1、be worth doing sth.值得(做某事);有(做某事)的价值
　　
be worth sth.用于“数量、持续时间等”的名词之后，表示某物价值多少金额。
　　The new car cost a lot of money, but it’s certainly worth it.
　　买这辆新汽车花了很多钱, 但确实物有所值。
　　The thieves stole one million pounds? worth of jewellery.
　　窃贼偷走了价值100万英镑的珠宝。

2、易混辨析
　　worth/worthy/worthwhile
　　“be worth+n.”结构中，当名词为金钱时，表示“……值……钱”。
　　be worth doing sth.　……某事值得被做
　　“be worthy of+n./doing”当名词为抽象名词时，表示 “……值得……”。
　　be worthy to be done/be worthy of being done
　　某事值得被做
　　It is worthwhile to do sth. 值得做某事
　　It is worthwhile doing sth. 值得去做某事
　　It is worthwhile for sb. to do/doing sth.
　　值得某人去做某事
