求一道SAT语法解答
Contrasting with most other fifteenth-century rulers, Portuguese kings could count on the support of the aristocracy in any overseas ventures.
答案是把头上改成Contrasted with. 为什么这里用被动.我在朗文词典上看到这样的例句：The snow was icy and white, contrasting with the brilliant blue sky.他比是自己跟别人比,又不是被比较.
字典里查出来contast作动词有两个意思：
1.使对比,使对照 vt
It is interesting to contrast the two proposals.
2.形成对照 vi
His actions contrast sharply with his promises.
这里我觉得是2，第一，解释的通（用法和上面的例句一样）；第二，它是不及物的。
是2的话，就是主动，就应该是CONTRASTING
求详细解释

这句中的contrast是第1个意思,contrast A with B.这种用法是个及物动词.
我们把你句中的前半句改成一个条件状语从句：
If Portuguese kings were contrasted with most other fifteenth-century rulers,
当然,你说也可以改成If we contrasted Portuguese kings with most other fifteenth-century rulers,
但是如果用第二句,主从句的主语不一致,就不能改成非谓语动词,除非用独立主格结构.和你的原题的答案明显不符.
所以用第一句,主从句的主语一致,这时,把条件状语从句改成非谓语动词：
1,去掉连词,
2,去掉主语
3,谓语是被动形式,改成了—ED形式.
