            Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved as a kind of snorkel.

(A) that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved

(B) that has suggested the elephant descended from an aquatic animal, its trunk originally evolving

(C) suggesting that the elephant had descended from an aquatic animal with its trunk originally evolving

(D) to suggest that the elephant has descended from an aquatic animal and its trunk originally evolved

(E) to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved

答案选D，我认同，可是A有什么错呢，its若按语法来讲可能是跟australian embryologists平行的，可它不可能指复数呀，那不也对吗？难道不能那么想吗？我不明白有点~~

A.that suggests that 两个that 累赘，
 , and          and 前的逗号必须去掉，因为都是suggest 的宾语从句，如果加逗号必须改为and that its trunk originally evolved as a kind of snorkel. 但这样又显得累赘。
所以run-on规则在D中也不是死板的，需灵活运用。

首先这个题选E,lz把答案搞错；呃。

A不好在 把 its trunk originally evolved和主句并列，你体会一下，都是是科学家的发现，不应该出来和主句并列。改成that its trunk originally evolved好一点。

另外 is descended from也是固定用法。

descend from 主动表示 从...下来；而不是 继承自...的意思。

            Hydrocarbons, with which fruit flies perfume themselves in species-specific blends, are known to be important in courtship, and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of others.

(A) and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of

(B) and apparently this assists flies when they taste the hydrocarbons on prospective mates in distinguishing their own species from those of

(C) which apparently assists flies that taste the hydrocarbons on prospective mates in being able to distinguish their own species from

(D) apparently assisting flies to taste the hydrocarbons on prospective mates to distinguish their own species from those of

(E) apparently assisting flies that taste the hydrocarbons on prospective mates in distinguishing their own species from

这E为什么对呀，我选D，想不明白呀~~

首先，这儿others本身就可以指代species，所以E完全是可以的，而D，those of显得相当累赘，同时，assist in 是固定搭配阿，最重要的是意思，D中是协助flies去taste碳水化合物，而原句意思是用那些品尝了碳水化合物的flies去区分～～～～

当然是越快越好啦，不过还得等磨快了我的宰牛刀再说。

alohabrian 大侠宰牛刀应该准备的差不多了吧，何时杀鸡，必来捧场，哇哈哈哈
