1. The first is a dubious
generalisation made by the greatest of novelists, Leo Tolstoy.
第二句可信度稍高一些,出自一名与伟大无缘的作家。
2. The laws governing our social life are not so clearly understood as to permit of a clear
generalisation.
我们现在还没十分懂得支配我们社会生活的那些规律,所以还不能构成很明白的一般概念。
3. A reasonable
generalisation from this rather small sample would be that "prosperous and constitutional democracies tend to live in peace with each other."
从这小样本得出的合理概括是:“繁荣的宪法民主国家一般可以和平地生活在一起。”
