今天我们来分享一下gamt语法中题干部分对我们的帮助吧在解题的过程中，很多考生会有个误区，认为划线部分是重心，所以非划线部分就不重要了，可以忽略不看。而事实上，这个观点是不对的，在题干的非划线部分，往往提供了各种宝藏信息哦。有利的非划线区域，往往可以帮助我们瞬间缩小选择范畴，降低题目的难度。

让我们借助下面的题目来切身感受一下吧！

In Scotland, thenumber of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting,by pollution, and by various other threats to the fish’s habitat.

(A) number of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting

(B) number of wild salmon is reduced because deep-sea and coastal netting is not controlled,

(C) numbers of wild salmon has been reduced because of uncontrolled deep-sea and coastal netting,

(D) wild salmon’s numbers are reduced by deep-sea and coastal netting that is not controlled,

(E) wild salmon’s numbers have been reduced by uncontrolled deep-sea and coastal netting,

在读该题目题干的时候，对考点敏感的同学应该会意识到划线部分的and，number of wild salmon have been reduced because of uncontrolled deep-seaandcoastal netting,迅速想到平行结构的知识点，那么该部分同学会陷入思考，and前后的并列是否对等，也就是uncontrolled deep-sea和coastal netting之间的对等关系。

但是真的应该先这么想吗？通过选项我们也可以看出来，这两者，uncontrolled deep-sea和coastal netting，根本不是考点所在。如果我们有耐心，有对非划线部分的谨慎意识，就会继续往后读，在划线区域后方，即by pollution, and by various other threats to the fish’s habitat.这部分，出现了一个很有价值的结构：by……，and by……在这里我们会发现如果是简单的A与B两者之间的并列，那么题干中是无需出现逗号。再同时结合选项，我们会发现，真正的并列结构应该是by A，by B，and by C。

(A) number of wild salmon have been reduced because of uncontrolled deep-sea and coastal netting

(B) number of wild salmon is reduced because deep-sea and coastal netting is not controlled,

(C) numbers of wild salmon has been reduced because of uncontrolled deep-sea and coastal netting,

(D) wild salmon’s numbers are reduced by deep-sea and coastal netting that is not controlled,

(E) wild salmon’s numbers have been reducedby uncontrolled deep-sea and coastal netting,

因此，答案迅速被锁定在选项D和E之间。五选一的题目由于对题目的推敲，瞬间变成了二选一。第二步，对比选项D和选项E，

(D) wild salmon’s numbers are reduced by deep-sea and coastal nettingthat is not controlled,

(E) wild salmon’s numbers have been reduced byuncontrolled deep-sea and coastal netting,

这时候不难发现，D选项的表达赘述冗余，因此答案直接锁定为E选项。

当然这道题目中还有一些别的知识点可以帮助我们找到正确的答案，在此提醒大家：

1.A选项中，主语number，谓语动词have，主谓不一致，错误。

2.B选项中，deep-sea and coastal netting后接谓语动词is，主谓不一致，错误。

3.C选项中，numbers of的用法错误。

4.D选项中，时态，应该选择用完成时态，减少这个动作，已经发生了。

所以，任何一道题目都不会是单一的语法点的考察，一定是各种语法知识揉杂在一起对我们进行考察。同时希望通过这道题目的分享，让大家能感受到非划线区域对我们的各种友好哦！
