10 阅读理解. Some people may say a hero is someone older than you, someone you personally know, someone who has done something everyone knows about, etc. I don"t think a hero necessarily has to be an older person or a close friend or a family member. My hero is younger than me, but we are related. His name is Marcus. He is my cousin. He isn"t necessarily a wise person or someone who does something great every day, but he has taught me to appreciate some of the simple things in life. I am now in 11th grade. When I was in 8th grade, Marcus had a brain tumor (脑瘤) which had to be removed. Thankfully the tumor was benign (良性的). When the doctors removed it Marcus lost his sight. He felt down only once. Ever since then, he has been an extremely happy second-grader. He is very typical of a nine-year-old. He likes to tell jokes, play new games, and he likes to play tricks on people, just like children at his age. I love spending time with him. We go to movies whenever there is a good one and look after him every chance I get. I say that Marcus helps to appreciate the simple thing in life. He doesn"t have his sight and that causes me to realize how lucky I am to be able to see, to walk, and to talk. I can do everything I need to. If everyone could see how happy and satisfied Marcus is and how much he makes everyone around him happy, then they might just be able to better appreciate the simple things in life. 1. It can be inferred that the author has_______. A. the same idea about heroes as others B. a different idea about heroes from others C. the idea that a hero must be older D. the idea that a hero must be a close friend 2. Why does the author consider his cousin as a hero?______ A. Because his cousin is a very wise person.. B. Because his cousin does great things every day. C. Because his cousin teaches him how to enjoy a simple life. D. Because his cousin teaches him to live a rich life. 3. What does the underlined sentence in Paragraph 2 mean?_____ A. Marcus looks older than his age. B. Marcus isn"t nine years old at all. C. Marcus is diffe rent from the other students. D. Marcus is the same as the other children at his age. 4. What makes the author think himself lucky?_____ A. Marcus" simple life. B. Marcus" serious illness. C. Marcus" blindness. D. Marcus" recovery.
