问题 New techniques in thermal-scanning photography, a process that records radiation from surface areas, makes it possible to study the effects of calefaction, or warming, of a river in greater detail than ever before.

选项 A、makes it possible to study the effects of calefaction, or warming, of a river in greater detail than ever before
B、make it possible to study, in greater detail, the effects of calefaction, or warming,of a river than ever before
C、have made it possible to study in greater detail than ever before the effects of calefaction, or warming, of a river
D、make possible the study of the effects of calefaction, or warming, of a river in greater detail than it ever was before
E、has made it more possible than ever before to study in greater detail the effects of calefaction, or warming, of a river

答案 C

解析 本句的主语new techniques决定其谓语应该为复数形式的动词,由此可排除A、E;D中有三个缺陷:(1)本句强调的是“进行研究”这个动作,而不是指“研究的结果”,用thestudy取代to study是没有道理的;(2)由句中的in greater detail表明了在此新技术存在之前已有过研究,那么用make possible the study就是前后矛盾的;(3)than ever before本身就是一种习惯表达,在than之后补出it反而是画蛇添足。B、C间的选择更为困难。细读B、C,两者之间有两点区别:(1)时态;(2)B中,in greater detail离比较词than很遥远,而C中两者紧挨在一起。从时态上,很难辨别孰对孰错;但根据它们在比较中的差异,完全可以断定C优于B。因为:B中形容词比较级作为插入成分而比较连词than却作为主要成分的表达,这是不可以接受的;同时,两者分隔太远也会影响表达效果。
