og41、大全465

41. Under a provision of the Constitution that was never applied. Congress has been required to call a conven­tion for considering possible amendments to the document when formally asked to do it by the legisla­tures of two-thirds of the states.

(A)  was never applied, Congress has been required to call a convention for considering possible amendments to the document when formally asked to do it

(B)   was never applied, there has been a requirement that Congress call a convention for consider­ation of possible amendments to the document when asked to do it formally

(C)  was never applied, whereby Congress is required to call a convention for considering possible amendments to the document when asked to do it formally

(D)  has never been applied, whereby Congress is required to call a convention to consider possible amendments to the document when formally asked to do so

(E)   has never been applied. Congress is required to call a convention to consider possible amend­ments to the document when formally asked to do so

选E，OG解释AB时说时态不一致

大全465

1.        Just as plant species native to regions with browsing mammals evolved many natural anti-browser defenses (such as sharp spines and toxic chemicals), so humans in malarial regions have evolved dozens of chemical defenses against malaria.

(A) so humans in malarial regions have evolved dozens of chemical defenses against malaria

(B) humans in malarial regions have been evolving dozens of chemical defenses against malaria

(C) there has been, in malarial regions, an evolution of dozens of human chemical defenses against malaria

(D) dozens of chemical defenses against malaria have been evolved by humans in malarial regions（A）

(E) similarly, in malarial regions, humans have evolved dozens of chemical

选A的话时态就不一致了啊，这两个题有矛盾吗？看过前面有人讨论说前面半句的evolved不是谓语，而是分词，那前半句的谓语是什么？

41。 A，B主句用has been，而它之前的法律实施应该比它早，所以不能用一般过去式。另外A，B的it不对。

465。这两个句子前后的时态不一定要一致。只是一个对比。plant species evolved defenc 对比humans have evolved defence并不矛盾。

前半句defences是谓语吗?

大全465：A不对吧，这样没有主句啊：just as...，so..

四个选项中，觉得B还算比较正确.

just as...,so...是一个固定的用法,XDF的讲义上有这道题,老师是这么说的

啊？我还不知道呢，谢谢楼上的。

BTW，B的谓语部分肯定是错的。

继续讨论

do so ，这里的SO代表的是什么，指的是前面的consider possible amend­ments to the document 还是is required to call a convention 还是整句话is required to call a convention to consider possible amend­ments to the document ？？？

选项我是能够正确的选出来的，只是这个SO很困惑，不知道在文中出现do so时so 对应的是句中的哪一部分？

谢谢。
