单元检测（五） A Lesson in a Lab.阅读理解ABeing in the schools science lab can be exciting, because youre doing something different from sitting at your desk listening to your teacher. But fun as lab work is, you have to observe the safety rules if you dont want to hurt yourself or your lab partner.The first rule is to behave responsibly in the laboratory at all times. When your teacher is showing you lab equipment, listen to what he is telling you, because some of the equipment can be dangerous.Bee familiar with your lab assignment (任务) before you start doing it. This means reading everything the teacher has written down and asking questions if you dont understand an instruction or a term.Do not try to work alone. If your partner is absent, let your teacher know so she can assign another student to work with you. And dont do any other experiments other than what you have been assigned. Wear your lab apron (围裙) and safety goggles (护目镜) whenever you are working on a lab assignment. On lab days, wear old clothing that you wont mind getting damaged. Make sure this clothing covers as much of your skin as possible. Keep your hands away from your skin, face, eyes and mouth when you are working with dangerous chemicals.You will be working with fire in the lab with an alcohol lamp. Use gloves when handling hot lab equipment. If you have long hair, pull it back in a ponytail (马尾辫) and roll up long sleeves. Dont put paper, chemicals, lab equipment or any part of your body in the flame.When you use a sharp instrument, treat it with care. Do not point it at yourself or any one of your fellow classmates during the experiment.语篇解读：在实验室做实验很有趣，但也处处存在危险。因此，遵守实验室的安全规则是很有必要的。1If you dont follow the safety rules, you will probably _.Abe laughed atBlose your lifeChurt yourself Dfail in the experiment解析：选C细节理解题。整篇文章都在告诉我们，如果不遵守安全规则，就有可能受伤。2The underlined word “observe” in Paragraph 1 means “_”Aobey BwatchCnotice Dreport解析：选A词义猜测题。根据第一段中的“if you dont want to hurt yourself or your lab partner”可推断出observe在句中的意思是“遵守”。如果你不想伤害自己或同伴，一定要严格遵守安全规则。3Having long hair can be dangerous when you _.Aroll up long sleevesBuse an alcohol lampCuse a sharp instrumentDwork with dangerous chemicals解析：选B推理判断题。第五段主要讲的是在实验室用酒精灯时要注意的事项。由此可推断出，长头发在使用酒精灯时可能有危险。4Whats the best title for the passage?AWays to do experimentsBExciting or dangerous?CSafety rules in the science labDObserve carefully in the lab解析：选C标题归纳题。文章主要讲的是在实验室要遵守的安全规则，故C项为最佳选项。B“I really like dancing，” says 11yearold Jonathan Rosario of New York City. “Thats what I want to be when I grow up a dancer.”Every Saturday, Jonathan and hundreds of other children from New York City public schools take classes at National Dance Institute (NDI). The nonprofit organization in Upper Manhattan was founded in 1976 by dancing star Jacques d Amboise, who grew up in a tough (充满犯罪与暴力的) neighborhood. It has been teaching school children how to dance through weekly classes for over 30 years. NDI also supports programs in New York City public schools, helping thousands of children to express themselves creatively.On a recent visit to NDI, I watched as Jonathan and other students practiced for an uping performance. I also spoke with d Amboise about the influence that dance has had on his life and why he started a program for children.“Dance changed me，” he said, “and Id like to see other young people especially boys have the arts in their life, using dance as a window.”For d Amboise, dancing is like petitive sports. Ice hockey (冰球) players, for example, “learn to pete as a single person and as a team，” he said. “They learn how to win or lose and accept either result. And they develop skills and unity by being on a team.” The same is true for dancers.Jonathan says that Saturdays at NDI are all about energy and fun. But dancing also requires great effort. “Work hard，” he advises other young people, “and youll make it.”语篇解读：本文是一篇记叙文。纽约市的一家非营利舞蹈机构每周给孩子们提供舞蹈课程，让他们感受舞蹈的魅力。5.
