请各位帮我，我语法不好！两道题目

computers are becoming faster, more powerful, and more reliable and so too are modems, they are the devices to allow two or more computers to share information over regular telephone lines.

我不理解为什么so too are modems的用法是对的? 我觉得重复了。 因为so are modems已经有too的意思了。

The end of the eighteenth century saw the emergence of prize-stock breeding, with individual bulls and cows receiving awards, fetching unprecedented prices, and excited enormous interest whenever they were put on show.

这个句子我不理解意思，也不太清楚结构，但是能选对。郁闷

这个问题以前也讨论过，不过没有定论。但是在New York Times里能找到一样的用法，可能起到强调作用吧。

Just as they have struggled with racism, poverty and despair, so too have many of the actors who have appeared in the plays, they say.

谢谢斑竹，我已经知道怎么查询语法题目了。

应该是强调吧。只要不是语法错误就好。 嘿嘿

GMAT语法是挑选最好的那个答案，并不是最正确的那个。
