To put that task in perspective, in the last 25 years, Greece ran an average primary deficit of 2% per year. To reduce the debt-to-GDP ratio to 70%, Greece would have to maintain an average primary surplus of 4% for the next 30 years, a level that it has temporarily achieved in only four of the last 25 years.&nbsp;
正确看待这一任务：过去25年间，希腊每年平均遭受2%的基本赤字。为把债务与GDP的比率降为70%，今后30年，希腊必须保持平均初级盈为4%，一个在过去25年间只有四年暂时到达的水平。
