同学好很高兴为你解答。
1 Europe produce countless Kings,nobilities,generals in the 13th century.
改为produces。
2 Even the professor who teaches history in the college.He doesn’t know their names.
改为Even the professor who teaches history in the college doesn’t know their names.
因为这里who已经引导了一个定语从句，修饰professor。主句结构是 professor doesn't know...
3 Even he doesn’t  have his own freedom.But he writes Aesop’s fables.
两个问题，首先，even不和but连用。去掉but。转折的语气要通过句子体现，不必加but。
其次，改为Even he doesn’t  have  freedom， he writes Aesop’s fables.
简洁明快，一目了然。
4 The history have the special sense of humor.
改为 has。
主语the history是三单。

祝天天向上！
