You are watching a film in which two men are having a fight. They hit one another hard. At the start they only fight with their fists（拳头）.But soon they begin hitting one another over the heads with chairs. And so it goes on until one of the men crashes through a window and falls thirty feet to the ground below. He is dead!
Of course he isn’t really dead. With any luck he isn’t even hurt. Why ? Because the men who fall out of high windows or jump from fast moving trains, who crash cars of even catching fire, are professionals（职业）.They do this for a living. These men are called stuntmen. That is to say, they perform tricks（骗局）.
There are two sides to their work. They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall on to hard ground but on to empty cardboard boxes covered with a mattress（床垫）. Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar!
But although their work depend on trick of this sort, it also requires a high degree of skill and training. Often a stuntman’s success depends on careful timing（计时）.For example, when he is “blown up” in a battle scene, he has to jump out of the way of the explosion（爆炸）just at the right moment.
Naturally stuntmen are well paid for their work, but they lead dangerous lives. They often get seriously injured, and sometimes killed. A Norwegian stuntman, for example, skied over the edge of a cliff a thousand feet high. His parachute（降落伞）failed to open, and he was killed.
In spite of（尽管）all the risks, this is no longer a profession for men only. Men no longer dress up as women when actresses have to perform some dangerous action. For nowadays there are stuntgirls too!

(答案→)C 解析：文章介绍了替身演员这个工作，特技演员并不是仅仅依靠trick（伎俩、把戏）来完成工作，还有技能和训练。【小题1】细节题：对于Stuntman（特技替身演员）的解释出现在文章第1段的开头举例之后，有关键字professional, do this for a living而判定为B选项。【小题2】细节题：根据Stuntman这类人的定义可知替身是出卖他们的特殊技能。A选项曲解了特技演员的谋生手段，而CD两项范围过小而排除。选B。【小题3】细节题：从第三段的内容，强调演员的生命安全是受保护的。 A项错在little的表述， little表示否定含义“几近没有”，与原文不符， B项错在是演员落下的地面上覆盖着床垫，而非演员被覆盖着床垫， C项与原文不符， 选D。【小题4】细节题：从第4段关键转折词： BUT。后面解释了特技演员并不是仅仅依靠trick（伎俩、把戏）来完成工作，还有技能和训练。以及一个关键短语depend on直指答案的出现为careful timing，仔细谨慎的（把握）时机，与B选项Exactness（精准）相符。 【小题5】排除题：CD选项很容易即被排除，而B选项是文中没有提到的关于意外发生比例的问题。选A。
