大家好，请问一下：
牛津双解第四版对vampire的解释是
vampire n.
reanimated corpse believed by some to leave its grave at night and suck the
blood of living people
如果是这样我可以理解
reanimated corpse believed to leave its grave at night and suck the blood of
living people
但它又加了by some（应该是指“被某些人”...）
如此的话，believed不是就被by some先“用掉”了吗？
变成reanimated corpse (believed by some) to leave its grave at night and suck
the blood of living people
这样意思能通吗？（也就是括号内可删去）
还是说believed既可以被by some使用，又可以再接to leave...
有这种用法吗？
谢谢！

不是每个人都认为有吸血鬼，也没啥东西能reanimated

reanimated corpse (that is) believed by some to leave你用的字典查 believe ，应该有相关句型(特别是例句):be believed to V ...你不熟悉 believe 的相关用法而已。不要过度复杂化"还是说believed既... 有这种用法吗？"-> 很寻常。倒是你怎么会以为by some之后就不能再继续接http://corpus.byu.edu/coca/ 左边搜寻方框输入下方believed by some to或是去掉 by some / 换用其它修饰词。你自己玩
