[求助]04-10真题请教

28. Paleoanthropologists examine fossil remains of extinct primates, while physical anthropologists concern with ethology study the behavior of primates in their natural settings.

答案是CONCERN,可是我不知道错在那里?

34. After the United States became independent, the cure of more fertile lands drew steadily New Ennglanders into the Ohio Vallye and the British colony of Upper Canada.

答案是B,也是不知道为什么错误

另问有没有人做了04-10真题的啊,我怎么觉得阅读部分的答案有些问题呢.还有听力,那里可以下载听力的题,真题里有答案但是没有题目.

28.应该是be concern with ,这是固定句型！！

34.more than 这也是固定的搭配，但是句子里没有than ，所以就是把more 去掉就可以了.

个人意见！！

现在更搞不懂34那个是对的了,你们给了两个答案
