学员疑问： 老师，The European Commission said on Thursday it would toughen the regulation of medical devices as a result of concerns raised by breast implants produced by the defunct French company PIP, even as a scientific expert review it ordered concluded there was currently "insufficient evidence" that women using its products faced greater health risks than others. 这个句子中expert review it ordered concluded 这里面科学专家认为，it指代前面加强监管医疗设备这件事，然后ordered concluded 这个该怎么理解？动词多的人眼花缭乱，不知所措了。
老师解答： even as（连词引导状语从句） a scientific expert review（主语） it ordered（省略关系代词的定语从句修饰做主语的名词a...review） concluded （谓语动词）there was currently "insufficient evidence" （宾语从句）that women using its products faced greater health risks than others.（同位语从句说明"insufficient evidence"表明的内容）
点评分析：该句体现的动词多的情况，也是英语的一大特点，解决这个问题主要还是在于是否能“提炼主干”，也就是句子，不论是主句还是从句，都有主干，都符合基本句型的某一种情况。此句疑问处，影响理解的应该是it ordered，一方面代词it指代The European Commission，另一方面省略了引导定语从句的关系代词which或that。
