[求助]HELP！马上要二战了，没人问过的GWD两题——GWD31-Q35和GWD25-Q17

35. GWD31-35

A consortium of historically Black colleges in the United States
            capitalizing on such schools traditionally rich relationships with
            African nations, integrates African concerns into an international business study

A.          capitalizing on such school’ traditionally rich relationships with African nations

B.          while capitalizing on the traditionally rich relationships of such schools and African nations

C.          through capitalizing on such schools’ and African nations’ traditionally rich relationships

D.          which capitalize on the traditionally rich relationships of such schools and African nations

E.          in capitalizing on such schools’ and African nations’ traditionally rich relationship

这题我犹豫很久还是选了B，看了答案后除了发现B多加了转折关系，实在看不出有社么区别，难道B会有 traditionally rich relationships of such schools and（of） African nations 的歧义？

Until recently, the Inuit people led a nomadic existence, sheltering in
                            igloos, the ice-block domes that are peculiar to north-central Canada,
                            and in structures made of stones, bones, driftwood, and skins.

A.      Until recently, the Inuit people led a nomadic existence, sheltering

B.       During recent times, the Inuit people lead a nomadic existence,
                            sheltering

C.      In the times that are recent, the Inuit people led a nomadic existence, sheltered

D.      Up until recently, the Inuit people, leading a nomadic existence, have sheltered

E.       Until recent times, leading a nomadic existence, the Inuit people
                            were sheltered

这题选是选对了，但是再看一眼，觉得D也挺好，recently 对应have sheltered，本来也看A中的led不顺眼，D是不是错在改变了修饰和动词的关系？

多问一句，until recently 正确时态应该是一般过去吗？

转折关系就是最大的区别 改变原意了

until recently 从来不要求必须用完成时 完成时和一般过去时都可以使用 根据意思判断
