答案

However,the rules are only embodied system-level things,the values system is （a） cornerstone to propel system establishment.Western (countries’)1 values are (included of two:)2 on the one hand,(Western countries value is)2 from the time of the French Revolution,liberty,equality and fraternity thinking.On the other hand,it is the transplantation by(of) traditional Western Christian culture.(The system of )3 Western countries is a kind of freedom alliance system,their strength(s) often come from the creation of free lethargy.
注：1,作为名词来用,负数后面该加撇号；如果当形容词,就该用 Western country values.
2,建议删除刮弧内文字,既然用on the one hand,On the other hand,这些就变得多余了,且使文章变得啰嗦,不流畅.如果要选择前者,只能二取其一,去除on the one hand,On the other hand,用数字1,2 代替.
3,在前面加 The system of 才能使 Western countries 复数后面的is 显得正确,所谓主谓一致也.
