【简答题】
This year, who “entertained us, challenged us and changed our world”? Absolutely(毫无疑问地), Jeremy Lin, an Asian-American NBA rising star, is one of those people. On April 18, TIME Magazine named him one of 2012’s Most Influential People in the World. Lin, 23, is not just a good basketball player, but also a graduate of Harvard University, one of the best universities in the world. “Lin has broken the idea that one can’t be a world-class athlete on the court and an excellent student off the court at the same time.” US Education Secretary Arne Duncan wrote in the TIME article about Lin. At 191cm, Lin isn’t especially strong, compared with other point guards (组织后卫) in the team. What makes Lin stand out from other players is his hard work and never-give-up spirit. “I know how the team works. I may not get an opportunity, but I’m just going to put it all into this and see what happens.” Lin once said. He kept arriving early, leaving late, practicing hard and learning from other experienced players. Finally, when his opportunity came, he started to shine. “He earned(赚得) it.” Duncan said. “He lives the right way, and he plays the right way. He works hard and stays modest. He sets a good example for young people today. ” 小题1:What did TIME Magazine name Jeremy Lin? A.He is one of the most influential people in the USA. B.He is one of the most influential people in 2012. C.He entertains us, challenges us and changes our world. D.He is an Asian-American NBA basketball player. 小题2:What makes Lin stand out from other players? A.His hard work.        B.Never-give-up spirit.   C.His opportunity.    D.Both A and B. 小题3:Why did Lin start to shine when his opportunity came? A.Because he graduated from Harvard University. B.Because he knew how the team worked. C.Because he practiced hard and learned from other experienced players. D.Because he is an Asian-American NBA rising star. 小题4:What does the underlined word “influential” mean? A.有影响力的 B.有价值的 C.有意义的 D.流行的 小题5:Which is the best title of the passage? A.Jeremy Lin’s School Life B.Harvard Owns the Best C.Hard Work Paid Off D.Teamwork Comes First
