大全637

637  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.

(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）

(E) are at least fifty percent less likely than those who are sedentary to die of a heart attack

看过前人的讨论了，但是还是有一点不明白，请大家指教：B和C中的or less 是不是插入语呢？大全简注上解释是“，or less”是个插入语，因此than没有比较的对象了；而另一种说法是B、C错在表达不够简洁上，即at least less than优于as...as, or less的表达（本题虽然不是这种标准形式，但类同）

请NN们确认一下

第二种说法更加准确有效

可是也的确觉得这里的“，or less”用法有些别扭，有谁在别的地方见过这种形式吗？

以B为例:(B) have half the chance, or less, of dying of a heart attack than those who are sedentary do

B中or为连词，如果拆开，大家就能看出错误在那里了。

（a）have half the chance of dying of a heart attack than those who are sedentary do

(b)   have less half the chance of dying of a heart attack than those who are sedentary do

(a)无论如何都是错误的。
