标题: 求教一道语法题！！！看之前的帖子都没看懂 [打印本页] 作者: richygogogo 时间: 2016-9-7 15:48 标题: 求教一道语法题！！！看之前的帖子都没看懂 In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystallizing and fungus was growing on the walls.
(A) due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystallizing
(B) due to moisture that tourists had exhaled, thereby raising its humidity to such levels that salt from the stone would crystallize
(C) because tourists were exhaling moisture, which had raised the humidity within them to levels such that salt from the stone would crystallize
(D) because of moisture that was exhaled by tourists raising the humidity within them to levels so high as to make the salt from the stone crystallize
(E) because moisture exhaled by tourists had raised the humidity within them to such levels that salt from the stone was crystallizing
我知道E是最好的，但是有几个问题：1，A选项中的which有没有指代不清的问题，我看og没有说这条所以想问一下；2，为什么og上面说C,D选项them是指代tourists，而不是指代Chambers，但是E里面的them就是指代Chambers，所以C,Dthem指代歧义，E没有指代歧义，为什么？3，due to在GMAT里面是不能作为正确表因果的连词吗？求大神指教！！！！
