哈喽同学们好呀,又是广州雷哥GMAT Sofia的SC小课堂时间~上篇文章中广州雷哥GMAT Sofia老师带大家了解了GMAT句子改错中的时态考点的基本语法规则:一,并列的两个句子或主从句一般时态保持一致,二,时间状语从句和条件状语从句中要用一般时态表将来。这篇文章老师带同学们从语义的角度补充下时态考点需要注意的问题。

我们结合一道例题来讲解一下。

Combining enormous physical strength with higher intelligence, the Neanderthals appear as equipped for facing any obstacle the environment could put in their path, but their relatively sudden disappearance during the Paleolithic era indicates that an inability to adapt to some environmental change led to their extinction.

A appear as equipped for facing any obstacle the environment could put in their path,

B appear to have been equipped to face any obstacle the environment could put in their path,

C appear as equipped to face any obstacle the environment could put in their paths,

D appeared as equipped to face any obstacle the environment could put in their paths,

E appeared to have been equipped for facing any obstacle the environment could put in their path,

解析:这里从but并列的另一个句中标红的indicates,我们可以排除DE选项,appear as,这里as介词要接名词,所以排除AC选项,最后选择D选项,根据老师之间给同学们讲的关于时态的语法规则很容易可以做出来。但这里老师要提醒同学们的是非划线的部分的led to,我们上面提到主从句时态一般保持一致,那么这里为什么不一致呢?其实这就是老师要给同学们补充的时态考点的语义考法,extinction灭绝是过去事实,所以这里从语义上来讲要用过去时态。

好~结合上面的方法,我们练习一道题目:

Ozone, a special form of oxygen that screens out harmful ultraviolet rays, reaches high concentrations twelve miles above Earth, where it has long appeared that it was immune from human influence; we have now realized, though, that emissions of industrial chlorofluorocarbons deplete the ozone layer.

A has long appeared that it was immune from

B has long appeared to have been immune from

C has long appeared as being immune to

D had long appeared immune to

E had long appeared that it was immune to

解析:看到这道题,有的同学会直接排除掉DE选项,因为主从句时态一般保持一致对吧,但是这里涉及到语义的问题哦,我们看下这题的语义,分号前面那句话讲的是,臭氧在距地球12英里的高空达到高浓度,长期以来似乎不受人类影响,而后面的句子说的是,现在,我们意识到工业氯氟烃的排放会消耗臭氧层,也就是说,现在臭氧受人类的影响了对吧,所以前后语义是相反的,那么肯定不会是同一个时态了对不对,这样的话,前面的句子就要用过去时态才合理,所以我们要在DE中选择,从简洁性考虑,D选项正确。
