og11紫书61,为什么要加it?

61, Archaeologists in Ireland believe that a recently discovered chalice,which dates from the eightth century,was probably buried to keep from being stolen by invaders

A,to keep from

B,to keep it from

C to avoid

D in order that it would avoid

E,in order that it would avoid

答案是b，为什么为什么？我认为不加it意思很明确了，答案说加了It指代才明确。

圣杯被埋是为了让"它"不被入侵者偷走,不加it,stolen没有直接意义上的逻辑主语

高不敢当,只是看了很多牛人的解释以后也终于感觉掌握些要领了,不过现在最主要也是回报cd,为大家服务了

陈向东的书里也有这题~他的答案是C,我也没有觉得C有什么不对~~~~~~~~~

keep sth from doing = avoid doing

但是后者比前者简洁啊

OG的解释说C也需要加it来避免歧义~

可是划线部分之后已经有stolen by invaders来避免产生歧义啊~!

觉得C比较正确啊............
