破解版的解释不是很懂啊……

再有三天就考了啊，但这几道题还是不懂。所以大家帮帮忙啊！大谢！

抛砖引玉一下 关于楼主的几道题我的理解是：

112. it是形式宾语，指代to引导的部分，即 to borrow

126. B的a vantage point指的是划线部分之前所叙述的内容，先不看其是否构成插入语，单从句子结构来看，后面的that引导了一个修饰point的定语从句，这样一来句子的结构就不完整了。

146. E的结构上是 "Gyrfalcon with numbers greater than (the numbers) when...." 显然比较的逻辑关系不对

     D同样存在这个问题

     从Gyrfalcon的单数形态可以排除C

     numbers的比较上应该该用greater而不能用more，所以排除B
