[求助]OG-175

175. Two new studies indicate that many people become obese more due to the fact that their bodies burn calories too slowly than overeating.

(A)  due to the fact that their bodies burn calories too slowly than overeating

(B)  due to their bodies burning calories too slowly than to eating too much

(C)  because their bodies bum calories too slowly than that they are overeaters

(D)  because their bodies bum calories too slowly than because they eat too much

(E)   because of their bodies burning calories too slowly than because of their eating too much

The members of a comparison (more X than Y) should be expressed in parallel form. D, the best choice, correctly uses parallel clauses introduced by because. The clauses them­selves are clear and direct. Choice E uses parallel forms, but the convoluted structures are awkward and wordy. Furthermore, the word bodies would need an apostrophe (bodies') since it is the logical subject of the gerund burning (that is, it answers the question, "Whose burning?"). A, B, and C do not use parallel forms for the two members of the comparison. In addition, A and B use due to unidiomatically to mean because; properly used, due to is synonymous with attributable to.

在og的解释中,它说due to 与 because 不同,而与 attributable to.同意.我查了词典也没发现什么大的不同,平时在用的时候也没有感觉这三个词的异同.

请教大家,从ets出题的角度来讲 ,这三个词的不同到底在哪儿?什么时候该用because,  due to or  attributable to?

due to 是个 prep. phrase + n. attributable to 类似

because是个conj.+clause

due to = because of

查了cobuild字典：

because of: If an event or situation occurs because of something, that thing is the reason or cause.

due to: if an event is due to something, it happens or exists as a direct result of that thing.

可见，due to < because of，而且两者用法也有小区别。

due to: A is due to B. A的直接原因是B。A, B一定都是名词。

because of: A exists because of B. A的原因是B，不一定是直接原因。且A、B可以是名词、动名词等。

我想问的是关于due to的省略问题.请问下面哪些话是对的:

Our declining health is more due to the polluted air than due to the polluted water. 

Our declining health is more due to the polluted air than to the polluted water.                                             省略due

Our declining health is more due to the polluted air than the polluted water.                                                  省略due to
