B: descended 变谓语为修饰语,改变原文意思,it trunk…优先修饰animal,有歧义。
C: 过去完成时没有意义,descended需要被动
D: descended需要被动,and后面需要加that

162. Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation, acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons (CFC's).
A. acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate
B. acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating
C. act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerating
D. they act as a global thermostat that thus keeps Earth either from burning up or freezing over, even though it also accelerates
E. they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate
A: correct
B: 无主句
C: act 的谓语结构应该是状语结构;无主句
D: 改变原意 (even though与前面的although重复,都是从句)
E: 改变原意 (although…, they act…, but they accelerate…,三个分句中第一个是although引导的从句,中间是主句,但后面又跟一个but引导的并列分句。这个句子结构是没有问题的)
thus副词不能连接并列的谓语act, keep(应将to改为连词and)
原文的acting and keeping是作benefit的伴随状语,解释如何benefit Earth。Although ice particles benefit..., they also accelerate the destruction... 原文要表达这样一个对比:尽管有益,也有害。
E. they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate
而E呢,如果这样的句子结构不算错,那它表达的意思也不符合逻辑。
Although ice particles benefit..., they act to keep...这两个分句之间本来没有这层让步转折含义(原文的关系应该算是递进吧),但因为they act...成了独立的句子,所以与前面的although状语从句联合,就不符合逻辑意思了。
再往后面的but... 又与although重复了(重复使用连词)。

A: but having 错;by constructing错,没有表示这个行为而是这个结果

CD: 没有谓语
E: correct
172. The hognose snake puts on an impressive bluff, hissing and rearing back, broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom, eventually, if its pursuer is not cowed by the performance, will fall over and play dead.
A. broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom,
B. broadens the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom,
C. broadening the flesh behind its head the way a cobra does and feigning repeated strikes, but it has no dangerous fangs and no venom, and
D. broadening the flesh behind its head the way a cobra does and feigns repeated strikes, but with no dangerous fangs and no venom, and
E. broadening the flesh behind its head the way a cobra does, feigning repeated strikes, but with no dangerous fangs and no venom, and
原句结构: The snake puts on an impressive bluff, hissing and rearing…, broadening…and feigning…, but it has no dagerous fangs and no venom, and eventually, [插入语if its pursuer is not cowed by the performance,] will fall over and play dead.
The snake puts on…, doing…, doing… and doing…, but it has…, and will fall…
AB: 两个动词之间应该有连词
A的结构是The snake puts on…, doing and doing, broadens…, doing but doing, will fall…,三个并列谓语put, broaden, will fall之间缺少连词。
B的结构是The snake puts on…, doing and doing, broadens…and feigns, will fall…,也是结构有问题,and的位置不对。
C: correct
D: broadening 和 feigns不平行;but with no 不如用句子表达好
E: broadening 和feigning之间必须有连词
注意:
1、but with no这种介词结构在GMAT里,都倾向用完整的句子方式进行表达
2、目的状语并列必须用连词不能用逗号,以前考过 |
