【简答题】
It was the summer of 1936.The Olympic Games were being held in Berlin.I had trained, sweated and disciplined myself for 6 years on the running broad jump.A year before, as a college student at the Ohio State, I'd set the world's record of 26 feet 8 1/4 inches.Nearly everyone expected me to win. I was in for a surprise . When the time came for the broad-jump trials(选拔赛), I was shocked to see a tall boy hitting the pit (坑) at almost 26 feet on his practice leaps.He turned out to be a German named Luz Long.He had easily qualified for the finals on his first attempt. A nervous athlete is an athlete who will make mistakes.I fouled (犯规)twice on my qualifying jumps.Walking a few yards from the pit, I kicked at the dirt disgustedly.Suddenly I felt a hand on my shoulder.I turned to look into the friendly blue eyes of Luz Long.'Hi, I'm Luz Long.I don't think we've met.' 'Glad to meet you,' I said.Then, trying to hide my nervousness, I added, 'How are you?' 'I'm fine.Something must be eating you.You should be able to qualify with your eyes closed.' He said. He seemed to understand my nervousness, and took pains to reassure me.Finally, seeing that I had calmed down somewhat, he said, 'What does it matter if you're not the first in the trials? Tomorrow is what counts.' All the tension left my body as the truth of what he said hit me.Confidently I qualified with almost a foot to spare. Luz broke his own record and pushed me on to a peak performance.The instant I landed from my final jump—the one which set the Olympic record of 26 feet 5 1/16 inches—he was at my side, congratulating me. 小题1:The author said ' I was in for a surpris e' because he _____. A.beat Luz Long B.met a great competitor C.qualified for the final D.joined in the Olympic Games 小题2:What can we learn about the author from the passage? A.He remained confident in the Olympic Games. B.He had qualified for the finals on his first attempt. C.He broke the world record of the running broad jump. D.He had prepared for Berlin Olympics in Ohio State. 小题3:What is the passage mainly about? A.A memorable experience in the Olympics. B.A reliable man in the Olympic Games. C.A surprising result in the Olympic Games. D.A good suggestion on how to win in the Olympics

【多选题】对系统的需求建模的用例图建模技术需要考虑:
A.
识别参与者。对于某个参与者,考虑其期望系统提供的行为或与系统的交互。
B.
将行为提炼成用例。完善其他用例。分解用例中的公共行为与扩展行为,放入新的用例中以供其他用例使用。
C.
创建用例图。如果需要,在用例图中添加一些注解或约束来陈述系统的非功能需求。
D.
如果需要,将具有相同特征的参与者使用泛化关系加以组织;对某些参与者应用一个构造型以便加深理解。
