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
我选的是C，为什么不对呢？
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。

(E) are at least fifty percent less likely than those who are sedentary to die of a heart attack
B为什么不对？：Several studies have found that the coronary patients who exercise most actively
have half the chance, or less, of dying of a heart attack than those who are sedentary do
前面用的是have,后面的用do, 很正确啊？为什么不对？恳请NN指点；

我觉得B的do补出的没错.这题我也错了.不是很理解.但是我想如果要解释,B的错不在do上.
我的看法:
A, half...as..语法上来说, as后面如果不补全助动词,那么as就是一个介词,翻译成"作为".而不能表示比较的意思,所以A错
B, have half the chance,or less,...这里or less是插入语,所以这个句子的主干,没有比较级,所以用than 不恰当. (和楼上一位说得一样).
C, 和B一样,没有比较级,所以不应该用than,而且 or less的插入语位置不对,
D, 有比较级,却用了as,没有用than. 而且as后面没有补出助动词 ARE.
E, 比较级,用than. 比较运动人和常坐人.但是我个人感觉后面 to die of a heart attact 有歧义,似乎只是修饰它前面的 those who are sedentary..我就是凭这个排除E的....
请路过的牛人指点一下吧..要崩溃了,都说语法好提高,我怎么还没有找到感觉

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
答案是E，
但对于E，还有疑问：
对于E，还有疑问：E后面的部分those (who are sedentary to die of a heart attack) 都成了修饰those的修饰语了，
有两种读法：
those (who are sedentary to die of a heart attack)
those (who are sedentary ）to die of a heart attack
那这样的话：(who are sedentary to die of a heart attack) 可能成了修饰those的修饰语了，
所以导致意思改变？
为什么E 还对，弄得我排除掉E 了，嗨！
