11.   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

Ans:E ，我选B，但是我觉得E怪怪的，怎么会coronary patients are at least 50%，换句话说就是patients = 50%，这样不是很奇怪吗？？应该是patients have 50% chance吧！！

请ｎｎ指点，谢谢

不是，你把句子就看了一半，coronary patients are at least 50%  less likely than ...to die

那请问一下，这里的likely就是adj.来修饰patients的吗？？如果是这样我大概了解

但是，这题实在不懂要怎么下手，觉得B也可以，可否提供一下解题的思路做为参考，谢谢！！

如果把句子简化成patients are less likely to die.是不是对结构把握比较清楚了。

A) 比较as没有相应的as出现。
B) than没有比较级, or less算是插入语。
C) 同理上。
D) 同理A。
E) best. 有less than, be likely to do。
