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

答案给的E，但我觉得E选项有问题，E中的to die of a heart attack的位置放在最后有歧义，变成只修饰比较对象的后者those who are sedentary，而按逻辑意思应该是修饰比较对象双方的。我觉得B比E更好，B的do与have对称，逻辑上也没问题。
谁能解答一下啊？

我的看法是B中have half the chance, or less, of 的表达应该不对，特别是这里的or less
    表示至少比比***多（少）比较有三种表达方法
    A is at least as great as B
    A is as great as B, if not more so
    A is as great as, or greater than, B

刚才没打完字，不知道碰了什么键，帖子就跳出来发了

     后面还有话：B这里的than 明显接在LESS后，那怎么和have half the chance并列呢？

可我还是觉得E有歧义啊

首先，half the chance可疑，没大见过这种用法。通常是half a chance(很少的机会）。其次，less 是相对于half the chance,即与half the chance 相比。后面的比较对象then..就似乎无从可比

to die of a heart attack的位置放在最后没有歧义。

这里是：be likely to do

B中than与什么比哪？？句子awkward.

Snazzy

right, A is less likely than B to do sth. but is 'die from heart desease' right??? thanks

请问，B选项的谁与谁并列？

B不是在less后面省略了chance吗？补全之后为：

patients A have half the chance, or less chance, of dying a heart attack than patients B.

这句话有什么问题呢？
