问题 Not all paleontologists agree that connections between the continents were (i)________just after the extinction of the dinosaurs. Some hold the view that North America, Asia, and South America had (ii)________immediately following the dinosaur extinction, pointing to (iii)________between ancient kinds of mammals that existed on all three continents at this time in support of their argument.
Blank (i)      Blank (ii)             Blank (iii)
A. significant D. lasting differences G. similarities
B. permanent   E. extensive contacts  H. intermediaries
C. limited     F. trivial likenesses  I. hostilities
选项
答案C,E,G
解析 首先解决后两空，通读句子，发现空格(ii)要填入的词直接决定了空格(iii)填什么，我们将此类空格关系题目称之为“联动”或者是“排列组合”。如果空格(ii)选择D选项，表示各个陆地之间有着很大不同，那么空格(iii)也要体现出不同的ancient kinds of mammals之间存在很大的不同，但是G、H、I三个选项并没有一个选项体现出mammals之间的不同，有的同学会选择D、I，但是动物间的敌对性是天性，并不能由此决定出不同陆地之间的差异性。如果空格(ii)选择E选项的话。表示不同陆地之间有着很大的联系，那么空格(iii)就要体现出不同陆地上的mammals之间存在一定的联系，所以这里应当选择G。E、G是一对合理组合，F、G组合相互矛盾，所以这里我们应当选择E、G。空格(i)表示并不是所有人都相信陆地间的联系是怎么样的，所以这里应当选择C项limited。
