写得真好.比我当年考研时写得好多了.
有几个地方,谈不上修改,只是探讨一下.
1、many foreign culture are fresh to us,which we can change our taste to after being tired of our old fashion in a bid to create new power to do things more enthusiastically.
culture有两个含义：（1）the customs and beliefs, art, way of life and social rganization of a particular country or group.这个cultrue是不可数名词.（2）a country, group, etc. with its own beliefs, etc.这个cultrue是可数名词.
贵文应当是第一种culture,所以没有用复数形式.但前面直接用many限制就不合适了.建议改成many kinds of foreign culture.
which we can change our taste to 强调的是“we”,但文中讲的是外国文化对我们的影响,强调的是“foreign culture ”.所以改成which can change our taste语意更顺些.
2、Only when we have the well understanding of different culture can we conquer the great amout difficulties which we wil encounter when we work with foreigners .
well 是副词,应改成good.
different culture改成different cultures.不可数名词表示种类,要用复数.
amout 后面要加of.
3、Only in this way can our country, our people enjoy a revival.
改成Only in this way can our country, our people and our culture itself enjoy a revival.
