大全38请教,恳求路过的NN指点

64.   According to a recent study, the elderly in the United States are four times more likely to give regular financial aid to their children as to receive it from them.

(A) the elderly in the United States are four times more likely to give regular financial aid to their children as

(B) the elderly in the United States are four times as likely to give regular financial aid to their children as it is for them

(C) the elderly in the United States are four times more likely to give regular financial aid to their children than

(D) it is four times more likely for the elderly in the United States to give regular financial aid to their children than they are（C）

(E) it is four times as likely that the elderly in the United States will give their children regular financial aid as they are

答案是C，我想问的是这题有没有指代的歧义，them和their似乎指代不同的对象，请NN指点？

aid做动词时是及物动词，后面直接加宾语不加介词。这里的aid是名词，与搭配无关。这里的to是修饰give的。

另外继续求问their和them的指代问题，望路过的NN指点。

我之所以回帖，只是想告诉楼主，或许 指代是一个没有标准答案的问题。

上面这个例子不同，并没有存在指代的歧义。

我也知道大家讨论指代歧义很久了，但其实大多数大家讨论的题目从逻辑意思上分析以后其实是没有歧义的。

但是在大全38中是两个明确给出的代词their和them，正是从逻辑意思上来看指代出现歧义。

这里我想弄清楚的是：（1）是题目本身有问题？还是（2）所有格形式的代词是不是可以指代不同物体？或者甚至是（3）相同的代词就是可以指代不同的对象？（当然这个不太可能）

这题我居然回过帖，自己做居然做错了

1问：铜LZ

2问：数字＋times后面有加more的结构吗，应该是...times(或数字) + as + 形容词或副词 + as...这样一个形式啊
