括号里为正确答案C，选项B 为unless there will be another doctor to testify
解释里说，The construction (y will happen unless x happens first) requires the present tense following the unless clause ,rather than the future tense used here. 这是说，unless 必须与一般现在时连用吗？
56.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
正确答案为B ，lz之前选的C，解释说 This suggeste that the chalice acts to prevent its own theft.The pronoun (it) is needed for charity
这个说改变句意lz大概能明白，本句的意思是说Chalice被别人烧来防止被偷走，而不是Chalice 自己烧自己防止被偷走，但是，为什么会少一个it 呢？是说要改成原句的意思就要加it还是说这个表达本身就ungrammatical? 如果句意就是 Chalice 自己烧自己防止被偷走 那还需要加it吗？作者: bun 时间: 2011-10-23 13:37
如果改成主动： someone buried Chalice to keep it from being stolen 加it 是因为keep和avoid的主语和宾语是不一样的 然后变回来 Chalice was buried to keep it from being stolen作者: guoshuyu 时间: 2012-1-24 11:24
up 楼上解释的很好！作者: zwhjzwhj 时间: 2015-1-10 21:59
为什么用avoid就是自己防止，而keep就不是呢？
如果用avoid加上it就对了吗
