每年的10月初到年底之前都会有一个考GMAT的小高峰，一些刚跟托福雅思分手的考G小白需要利用这段时间去考G，还有一些考G的老油条需要利用这段时间去刷高分，无论如何这段时间会看到各位G友与GMAT斗智斗勇，也会有各个小伙伴问一些与考试相关的各种问题。
今天一个考G老油条问我到底什么时候用V-ing到底什么时候用动词表并列。一般小白会问什么时候用V-ing什么时候用Which，这个非常简单。我们今天要讨论困扰着老油条v-ing和并列的点。
澄清一点：
并列是指前后词，短语，从句或者句子在同一个意思层面就可以并列。
V-ing出现在主句后面：1表示前面事情带来后面结果2表示前面主句谓语动词和V-ing中的动词v同时进行。
既然如此，要区分是并列还是用V-ing就需要看两个动词之间有无因果关系。如果有因果关系则用V-ing,如果没有因果关系并且是两个无关得事情的话则用并列。
以下例题均按照如下方法讲解：
1 判断选项里面有无V-ing和并列的考点
2 找出主句动词,判断关系
判断主句谓语动作和V-ing中的动作V有无因果关系。如果有用V-ing表达，如果没有就用并列的表达。
例一：
Among theTsonga, a Bantu-speaking group of tribes in southeastern Africa, dance teamsrepresent their own chief at the court of each other, providing entertainment in return for food, drink, and lodging .
A the court of each other , providing entertainment in return for
B the court of another and provide entertainment in return for
C the court of the other ,so as to provide entertainment as a return on
D each other`s court ,entertainment being provided in return for
E another`s court and provide entertainment as a return on
1 判断选项里面有无V-ing和并列的考点。
根据划线部分有providing，和BE选项里面都有并列，所以考点符合。
2 找主句谓语动词，判断关系。
主句谓语动词是present，V-ing中的动词是provide, 团队代表首领和团队提供娱乐两者之间没有因果关系，所以原句也就是说了两个孤立的事，所以要用B和E中的并列，到底是B还是E，大家先自己思考一下吧。
例二：
To attract the most talented workers, some companies areoffering a wider range of benefits, letting employees pick those most important to them.
A benefits, letting employees pick those most important to them
B benefits, letting employees pick the most important of them to themselves
C benefits and letting employees pick the most important to themselves
D benefits and let employees pick the most important to them
E benefits and let employees pick those that are most important to themselves
1 判断选项里面有无V-ing和并列的考点。
根据划线部分有letting，和CDE选项里面都有并列，所以考点符合。
2 找主句谓语动词，判断关系。
主句谓语动词是are offering，V-ing中的动词是let, 公司提供更多选择，所以员工可以从中选择最好的。前后两句话有因果关系，所以用letting，而不用并列。在AB里面选，具体答案是什么大家先思考一下吧。
例三：
Between 14,000 and 8,000 B.C. the ice cap that covered northern Asia, Europe, and America began to melt, uncovering vast new areas that were to be occupied by migrating peoples moving northward.
A began to melt, uncovering vast new areas that were tobe occupied
B began melting, to uncover vast new areas to beoccupied
C began, by melting, to uncover vast new areas for occupation
D began, after melting, uncovering vast new areas whichare to be occupied
E would begin to uncover, through melting, vast new areasfor occupation
1 判断选项里面有无V-ing和并列的考点。
根据划线部分有uncovering，所以考点符合。
2 找主句谓语动词，判断关系。
主句谓语动词是began to melt ，V-ing中的动词是uncover , 雪开始融化，所以很多新的地区会暴露出来，前后两句话之间有因果，所以考虑用Uncovering形式。剩下AD两个选项，到底选哪个大家也可以再考虑一下。
例四：
Before 1988, insurance companies in California were freeto charge whatever rates the market would bear,needing no approval from regulators before raising rates.
A needing no approval from regulators before raising
B and it needed no approval by regulators before raising
C and needing no approval from regulators before they raised
D with approval not needed by regulators before they raised
E with no approval needed from regulators before the raising of
1 判断选项里面有无V-ing和并列的考点。
根据划线部分有needing和BC里面的并列，所以考点符合。
2 找主句谓语动词，判断关系。
主句谓语动词是were free to charge ，V-ing中的动词是need 。保险公司可以自由收费，所以它们不需要批准，前后因果逻辑关系，所以用needing,直接选A。
上述题目的参考答案：
BAAA
