问题 Several studies have found that the coronary patients who exercise most actively have half or less than half the chance of dying of a heart attack as those who are sedentary.

选项 A、have half or less than half the chance of dying of a heart attack as those who are sedentary
B、have half the chance, or less, of dying of a heart attack than those who are sedentary do
C、have half the chance that they will die of a heart attack, or less, than those who are sedentary do
D、are at least fifty percent less likely to die of a heart attack as those who are sedentary
E、are at least fifty percent less likely than those who are sedentary to die of a heart attack

答案E

解析 A中less than与as不能搭配;B、C中than之前无比较级出现(less than是与之相并列的部分);D中be likely as同样不能搭配;E中的at least就消除了“同级和比较级共用一个than的误解”。to die of a heart attack是修饰likely,因为该短语较长,所以后置,同时E的be likely to dosth.符合习惯用语的表达。类似的还有be committed/inclined to do sth.(倾向于做某事)。
