是一本叫做Verbal Workout for theGMAT的书，这道题不是题目，而是举得一个例子，答案是D。我刚刚入门，英语基础不太行，目前刚在看Manhattan 5th，语法知识点还是很模糊，所以搞不太明白，谢谢你了~

你确定这是一道GMAT题吗？
这道题考察的基本都是单词的固定搭配和用法，这不是GMAT的SC的考察趋势啊。这更像是纯语法考试的考法。

我试试吧
这道题应该选D
A. Attempt at doing sth的固定搭配中attempt是名词。
B.The attempt at curbing the infesting of Lake Victoria of the water hyacinth变成一个名词词组（attempt是名词），an ornamental plant which...还是做同位语。但主句ecologists are introducing weevils and fungi into the lake’s ecosystem.主谓宾都齐全，The attempt at...不做句子成分。
C.which had been infesting Lake Victoria and had been native to 中过去完成时用的不合理，没有明确的过去时间节点。
D.curb的是infestion，而不是the water hyacinth。
E. By attempting to curb Lake Victoria’s infestation of the water hyacinth,表示手段，不表示目的，改变了句意。

对吗？
