42. The current administration, being worried over some foreign trade barriers being removed and our exports failing to increase as a result of deep cuts in the value of the dollar, has formed a group to study ways to sharpen our competitiveness.

(A)  being worried over some foreign trade barriers being removed and our exports failing

(B)  worrying over some foreign trade barriers being removed, also over the failure of our exports

(C)  worried about the removal of some foreign trade barriers and the failure of our exports

(D)  in that they were worried about the removal of some foreign trade barriers and also about the failure of our exports

(E)   because of its worry concerning the removal of some foreign trade barriers, also concerning the failure of our exports

answer:c

我的理解：

句子的谓语是：has formed ……

worried about 做定语修饰主语，只不过有省略，完整的定语应该是 that is worried about the removal of ......

worried 在这里是形容词

个人认为 用worry的动词形式也是可以的，省略之后为 worrying about 后面与C选项的后面部分一样，也不算错误的。

偶是新手，意见仅供参考，嘿嘿，不知道有没有说清楚呢。
