Give a brief answer to each of the following questions in English.
What is Hemingway “Code Heroes”?
【正确答案】：
HEMINGWAY’S WORLD IS LIMITED. HE DEALS WITH LIMITED RANGE OF CHARACTERS IN QUITE SIMILAR CIRCUMSTANCES AND MEASURES THEM AGAINST AN UNVARYING CODE, KNOWN AS “GRACE UNDER PRESSURE”, WHICH IS ACTUALLY AN ATTITUDE TOWARDS LIFE THAT HEMINGWAY HAD BEEN TRYING TO DEMONSTRATE IN HIS WORKS. THOSE WHO SURVIVE IN THE PROGRESS OF SEEKING TO MASTER THE CODE WITH THE HONESTY, THE DISCIPLINE, AND THE RESTRAINT ARE HEMINGWAY CODE HEROES. 
【题目解析】：本题考查海明威笔下的英雄的特点。海明威的世界是有限的。他在相当相似的环境中处理有限范围的人物，用一种不变的准则来衡量他们，这种准则被称为“压力下的优雅”(grace under pressure)，这实际上是海明威一直试图在他的作品中展示的一种生活态度。那些在追求以诚实、自律和克制来生存下来的人是海明威式的英雄。
