10、hat are这道题应该选 A以上的这些例子都是属于独立主格结构的题型，大家目前应该都有点感觉，但具体独立主格结构是什么，该怎么样判断和使用独立主格结构，相信大家一定还不是非常清楚。这个专题，夏老师就告诉你们怎么样判断独立主格结构怎么样判断独立主格结构，甚至我们在 GMAT 写作中也能自由使用独立主格结构这种高级技巧，相信这种技巧使用起来就像篮球场上的 crossover, 或者足球场上的马赛旋转一样，引来一片尖叫。先看看我给独立主格结构下的定义：所谓独立主格结构所谓独立主格结构（absolute construction），是指句法上游离于句子主体之外，跟主句没有任何句法以及语法方面的联系；
11、但其在意义上却与主句紧密联系在一起，共同构成一个完整的语义环境。独立主格结构没有谓语，只有逻辑上的主语，因此，它在句法上不是句子，而是一个独立于句子成分之外的独特结构形式。 独立主格结构可置于句首、句尾，用逗号与主句隔开。这句话很抽象，我们来看几个具体的例子：I heard that she got injured in the accident，my heart full of worry我听说她在这场事故中受了伤，内心充满担忧。 He stood silent in the moon-light，his door open月光下，门开着，他默默地站立在那。 Winter coming，it

13、进了树林。 Nobody in，the thief took a lot of things away由于没有人，小偷拿走了许多东西。 Lunch over，he left the house午饭结束，他离开屋。 He fought the wolf，a stick his only weapon他和狼搏斗着，唯一的武器是一根棍棒。发现规律了没有？还没发现规律吗？以上这些句子，都是以逗号隔开的，其中一个部分是主句，主谓宾成分完美无缺，但另外一个部分似乎不以上这些句子，都是以逗号隔开的，其中一个部分是主句，主谓宾成分完美无缺，但另外一个部分似乎不是个完整的句子，缺少了啥？是个完整的句子，缺少了啥
14、？ 对，缺少了一个对，缺少了一个 be 动词。动词。也就是说，如果我们把 be 动词加到这个部分中，这个句子就是一个完整的句子，完美无缺。而且和主句在逻辑上是有联系的，所以我们可以用分号连接它们。比如：I heard that she got injured in the accident，my heart full of worryI heard that she got injured in the accident; my heart was full of worryHe stood silent in the moon-light，his door openHe stood sile
15、nt in the moon-light; his door was openWinter coming，it gets colder and colderWinter is coming; it gets colder and colderMore time given，we should have done it much betterMore time is given; we should have done it much betterThe boy stood there，his right hand raisedThe boy stood there; his right han
