109. Among the objects found in the excavated temple were small terra-cotta effigies left by supplicants who were either asking the goddess Bona Dea's aid in healing physical mental ills or thanking her for such help.

A in healing physical mental ills or thanking her for such help.

E to heal physical and mental ills or thanking her for such help.

正确选A 这里我有个问题， 不是aid 是接to的么？这么aid in healing是正确答案了呢

140. Rock samples taken from the remains of an asteroid about twice the size of the 6-mile-wide asteroid that eradicated the dinosaurs has been dated to be 3.47 billion years old and thus is evidence of the eariliest known asteroid impact on Earth.

A    has been dated to be 3.47 billion years old and thus is

C    have been dated to be 3.47 billion years old and thus are

E    have been dated at 3.47 billion years old and thus are

正确是E      我这里真的不知道该用dated to be 还是dated at .   另外还有什么estimate to be (at)之类的我也分不清楚，有没有同学清楚的，帮我解答下to be  和at  分别在哪种情况下用好么

1. aid我不是很懂，不过这里aid是名词，后面就用in了，是不是这个原因？

2. date at是固定结构，俺碰到好多次了。

jy03161061

恩~~date at 估计是固定的,estimate to be 估计也是固定的

另外我见过aid 是名词的时候用aid to 的情况....很困惑阿

这里应该是考平行结构吧ask in doing...or doing

amumu

这里的平行应该是either asking ... or thinking。

aid to我认为是动词的时候用的，比较to do表示目的性，前面总要有个动词，而aid在这里是名词啊。

张大猴

aid作为名词，aid in doing sth. / aid to doing sth.(to作介词)
aid作及物动词，aid sb.;   aid 作不及物动词，aid in doing sth.
