2015上半年GMAT模拟试题：语法
Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting its outer envelope of gases to become a white dwarf.
　　(A) Like any star of similar mass would do, once the Sun has exhausted the hydrogen in its core, it expands into a red giant, eventually ejecting
　　(B) Like any star of similar mass, once the hydrogen in the Sun's core is exhausted, then it expands into a red giant and eventually ejects
　　(C) As in the case of any star of similar mass, once the hydrogen in the Sun's core is exhausted, it will expand into a red giant, and eventually ejecting
　　(D) As any star of similar mass would, once the hydrogen in the Sun's core is exhausted it will expand into a red giant and will eventually eject
　　(E) As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core, it will expand into a red giant and eventually eject
　　原文意思： 象其他质量相同的星一样，一旦太阳消耗完了它的氢气，太阳就会扩张成红矮星，最终喷射 出一些气体变成白矮星。
　　题目分析： A 干掉，原因是 like any star 在逗号后面没有马上说谁不象那个 any star（记住，说了不 行必须是马上说，那个 once 不行） 。B 逗号后面用 hydrogen 就更不靠谱了，干掉。C 中的 it will expand 中的 it 按照道理应该指的是太阳，但是前面没有说过太阳，干掉。D as any star，逗号后面说氢气，不行，干掉（为什么 C 我不这么讲，因为 C 前面加了 in the case of）E 为什么 once 就没有事情，因为不失前面的 any star 和后半句进行对比，是 the case 和后面的某个 case 进行对比，once 就已经开始说 case 了，没有问题，并且 it 指的太阳前 面说过，没有问题，选 E。
