gmat语法部分要求句子表达清楚、无歧义、简洁等等,第一题,C选项的问题显而易见与句子原意不符,提炼原句主干原句说a technique （called proton-induced x-ray emission）can quickly analyze the chemical elements in almost any substance without destroying it而C选项将句子主语
a technique 置于句首,导致 which can quickly analyze the chemical elements in almost any substance without destroying it修饰的是前面出现的先行词emission.can quickly analyze the chemical elements in almost any substance without destroying it的动作发出者应该是a technique .
第二题,D选项将修饰完全打乱,原句要表达的意思是Beatrix Potter（人）,In her book illustrations,which she carefully coordinated with her narratives修饰人,动作capitalized on her keen observation and love of the natural world.D选项,将主语Beatrix Potter（人）夹在2个修饰成分中间,并且第一个修饰 Carefully coordinated with her narratives,修饰的是人,原句要表达是her book illustrations 被Carefully coordinated with her narratives,而不是D选项人被Carefully coordinated with her narratives.我刚考完GMAT 710分,如果你有什么问题或者疑问可以问问我
