SC - I'm died - so frustrating - help

qiufeng1990

Several studies have found that the coronary patients who exercise most actively (are at least fifty percent less likely than those who are sedentary to die of a heart attack. )

b) have half the chance, or less, of dying of a heart attach than those who are sedentary do.

b的than好象没什么根据，a把to die of a heart attack放在句末又令人很难理解

A
have the chance of doing...这个表达方式好像不够idomatic

同意楼上 B 中应用 have the chance to do sth.
还是不解 A :than 比较的是主语 the coronary patients who exercise most actively 和 those who are sedentary，是不是系动词 are 省略了 -

are at least fifty percent less likely than (are) those who are sedentary to die of a heart attack.
能否解释一些什莫时候省略谓语。
A study commissioned by the Department of Agriculture showed that if calves exercise and associate with other calves, they require less medication and gain weight more quickly than those raised in confinement.  
可否在than后省略 do ？？？？

1、是省略了。因为省略后没有在意思上引起歧义，所以是可取的。
若是省略后引起歧义，则必须补出。你可以查看前面的帖子，有专门讨论省略的。参与讨论的有sunny、tongxun等，好象帖子数超过10。具体是哪个我不记得了，好象是由usal，are usal 引起的讨论。
2、可以。补出也不错。
