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.

Worried 和 has formed???两动词？还是说可以理解成 （which) worried.....

主语部分：The current administration

谓语部分：has formed a group to study ways to sharpen our competitiveness.

状语部分：worried about the removal of some foreign trade barriers and the failure of our exports

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

选C的原因：The current administration被the removal of some foreign trade barriers and the failure of our exports 两个事件所WORRY，所以WORRIED此地是被动语态。

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

删B的原因：

1.) worrying over表主动语态，意指主语The current administration烦扰the removal of some foreign trade barriers and the failure of our exports 这两个事件,(逻辑不通)；

2.）, also 不等于AND，不能连接两个短语；

3.）第2个over 冗长；

4.）being removed < the removal (VING形式小于抽象名词的名词原形);BEING绝大多数情况下错,除PREP.+BEING+PP.
