the lesson to seniors frome financial cr**** last year the financial cr**** hit most part of the world.from the us to european coutries,even our country had a infection. what a big trouble it bringed in for our human beings!thousands of companies closed,numberous of workers lost their jobs,and the ranking systems were in bad condition. it will last a long time.it tought us an important lesson.first,the world wide trade system not only has advantage but also has many d**advantages.second,we should not depend on the abroad market too much,or we'll be influnced by it deeply.besides,we shoud promote our own competive power. i believe that it won't take us long to overcome the finacial cr****!
