OG183 请教!

海蓝

Archaeologists in Ireland believe that a recently discovered chalice, which dates from the eighth 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 to keep from

答案是B, 我选成了A, 逻辑上是不太合理~~汗~~
投机一下,请问,这种需要补出代词的情况都有哪些啊?~~
这道题是因为被动语态导致的.还有什么别的情况吗?~~
谢谢!

为什么我的大写字母都成了小写?~~郁闷~~

这题我也有疑问。 我觉得在og中所有动词都应该有其执行的对象，除了被动语态。 但在这个题中 并没有指出谁是keep的执行者， 这是问什么？

关于海蓝的问题， 其实这里补出it就是因为：如果没有"it", keep from就是chalic发出的了，导致歧义.

为什么C不对呢？应该有个it 的，好像楼上说得那样，可是avoid 为啥不对?

对选出答案已经完全没有问题了,但是我对OG的修改方案存在非常大的疑惑:

OG说C. Pronoun it is needed for clarity.

如果加的是it,不就成了avoid sth doing这种结构么,该结构我闻所未闻.

只看见过avoid sth/doing sth.  我觉得这里明明应该加its  .加的是its 的话就应该属于avoid sth.这种结构

大家认为呢?   欢迎指教

今天再次看到这道题，又查了一下longman，觉得其实longman已经把问题解释了
keep from something phrasal verb

 
1   keep somebody from doing something
His ex-wife had kept him from seeing his children.
I hope I haven't kept you from your work.
   
2  keep something from doing something
Put the pizza in the bottom of the oven to keep the cheese from burning.

3   keep (yourself) from doing something
The play was so boring, I could hardly keep myself from falling asleep.
这道题如果没有it ，就是属于第三种用法，但是动作的发出者不对，所以应该用第一种用法，补出it
