主语是Organization，谓语had been expected，but连接两个句子，第二个句子的主语是officials，谓语announced。后面有宾语从句，从句主语是group，谓语will pare。后面又有but连词，连词后面为if从句。但是在but前并没有语义相似的从句与if从句平行。因此可以排除AB。从结构上也可以排除D选项。D选项中which从句修饰nations，所以这个从句中逻辑上的主语是nations，谓语不应该用单三形式。BD比较，在于if从句中的谓语是否应该加would，结合我们学的if从句表条件或虚拟的两种情况。如果只是一般的条件句，主句和从句中都不会出现would，should，may，might等情态动词。如果是虚拟，只有主句会出现这些情态动词（从句中只可能出现should这一个词，其他的还有were，were to）。所以排除C选项。&

主句中发现是so。。that的句型，表示结果。原文结构没有什么问题。B选项逗号连接两个句子，句子结构错误，直接排除。C选项没有了so
。。that的固定搭配，改变原文语义，排除。D选项和C有同样的错误。E选项把it指代schistosomiasis去掉了，变成了there be句型，改变原文语义。在GMAT中，有一个非常严谨的指代，就是主句的主语和状语从句的主语可以互相指代。

主语Rabindranath Tagore，谓语 had，but连接两个句子，第二个句子主语Tagore，谓语had been。还可以看出有admiration的固定用法。比较选项差异，admiration后加for还是of是一个考点，介词出现区别一定会出现固定搭配的考点。Admiration后应该是for。排除DE。ABC的区别在the person之前要不要加as。不加as的话Mohandas K. Gandhi和the person就是两个名词连用，会出现修饰重心不明确和固定搭配的错误。所以A排除。C选项出现not only。。but的平行，明显介词词组不能和句子平行，排除C。

主语figures，谓语seem，like后有句子，这个用法是错的，like是介词，后面只能用名词。比较选项差异，B选项as if为从句，后面应该加句子，所以B在固定用法上错误。C seem to do固定用法正确，that后是从句。Economy is。。。，正确DE选项的后半部分都不能在结构上解释为什么唯有economy is。。。

提主干，看考点。
主语Jacqueline Cochran，谓语held，and连接两个句子，第二个句子主语she，谓语earned，之后是时间状语从句，从句主语aviation，谓语was。后面结构中有she flew，这个要么是句子，要么是从句，还有be of这种不太常见的表达，所以原文的语义应该是比较凌乱的。比较选项差异，BC都是句末doing的结构，这个结构是作为状语，是修饰整个句子或句子中的谓语的。DE为earned，ed的句末结构，这个结构是修饰逗号前的名词record的。从语义来看，直接用earned修饰records比较简洁。比较DE发现有so& that的固定用法，D选项是so that和such that一块用了，重复语义，固定用法错误。排除之后只有E选项比较合适。

主句前是前置的状语，主句主语是survival，谓语depends，后面是if从句。可以从主谓信息来看，if在这里是&是否&的意思。在GMAT里面，表达是否最好用whether，所以A排除。C选项whether or not啰嗦，语义重复。DE改变原文语义。原文表达依赖于是否能broaden and leave，而DE直接是依赖于能力，这个能力可以是大小，和原文的是否不一样。

这个题选错也不要紧，但是我记得在课堂上讲过A和E的区别。他俩只是调换了主干和非主干上的信息，也就是说关键信息的顺序调换了。没什么语法错误。我们认为这种情况下更加有逻辑语义的谓语代表了最关键的信息，outnumber表示比较，所以应该放在主干上。
AE的区别就是were written应该作为谓语还是outnumber应该作为谓语。以后见到这种情况，把有具体逻辑语义的放在谓语位置上。Were written是静止的，描述性的，而outnumber是比较，有具体逻辑语义的。显然outnumber比较适合放在谓语位置。&

主语是bats，谓语是play。逗号后aiding是状语。原文有平行，aiding&; pollinating&；and help&.分号表示列举。
从常识来看，不可能是play和help的平行，所以原文句子结构有问题。当然，这个也可以通过比较选项差异看到。
AB差异。A的可作为谓语的help变成了helping，与aiding和pollinating平行。因此B选项结构上没有问题。C选项，原文第一个分号明显是列举，在状语aiding和pollinating之间。但是C选项第二个分号就变成了连接两个句子，后面的句子是they help。。因此C选项明显改变原文语义。D选项把pollination之后的语义从状语变成了有主语they的句子。结构的改变引起了语义的改变。E综合了C和D的错误。&
