Hermann Ebbinghaus was the first person to study learning and memory by carrying out an experiment on himself. / He learnt lists of meaningless syllables and tested himself at different times. His findings changed the way we think about memory. / Forgetting happens fastest in the first nine hours. After about nine hours, people have forgotten around 60 per cent of what they tried to learn. After 24 hours, they have forgotten about two-thirds. This is the famous “forgetting curve”. It starts with a sharp drop and then becomes a gentle line. / Ebbinghaus also found some good news. Things we study longer and more carefully stay longer. Things close to the beginning and the end of a list are remembered most easily. Meaningful things are remembered about ten times longer than meaningless ones. And it is easier to relearn something than to learn it for the first time. / His work encouraged scientists to explore memory further, and it helped create proper methods for experiments in psychology. 任务一：单项选择 1.How did Ebbinghaus study memory? A.By testing other people. B.By experimenting on himself. C.By reading books. D.By watching children. 2.About how much have people forgotten after 24 hours? A.Ten per cent. B.One-third. C.Two-thirds. D.Nothing. 任务二：判断正误(T/F) 3.Forgetting happens fastest in the first nine hours. (　　) 4.Meaningless things are remembered longer than meaningful ones. (　　) 任务三：简答 5.What does the forgetting curve start with? _______________________________________________________________________________________________ Passage2（课外同源：间隔重复实验） 　　Li Wen is a student at a middle school in Nanjing. Last term, she did a small experiment for her science project. / She chose forty English words that she did not know. She divided them into two groups. She studied Group A for twenty minutes on Monday, and then studied it again for twenty minutes on Thursday. She studied Group B for forty minutes on Monday only. / On Friday, she tested herself. For Group A, she remembered 34 words. For Group B, she remembered 21. / “I was surprised,” she says. “I spent the same time on both groups, but the result was very different.” / Her teacher explained. “When you study something twice, with a break in between, your brain has time to store it. This is called spaced repetition. It works better than studying everything at once.” / Li Wen now uses the method for all her subjects. “I study for twenty minutes, then take a break,” she says. “And I review after a day, a week and a month. It really works.” 任务一：单项选择 1.How many words did Li Wen remember from Group A? A.21. B.34. C.40. D.20. 2.What is the method called? A.Spaced repetition. B.Fast reading. C.Mind mapping. D.Group work. 任务二：判断正误(T/F) 3.Li Wen spent more time on Group A than on Group B. (　　) 4.Spaced repetition works better than studying everything at once. (　　) 任务三：简答 5.Why does studying something twice with a break work better? _______________________________________________________________________________________________ 任务四：单元微写作 请根据遗忘曲线，为同学设计一份背单词计划，不少于6句话。请写清什么时候复习、为什么这样安排以及你期待的效果，并用上 review 和 curve。 _______________________________________________________________________________________________ _______________________________________________________________________________________________ _______________________________________________________________________________________________ 参考答案 夯实基础 一、单词汉译英 1.curve 2.forget 3.memory 4.experiment 5.hour 6.per cent 7.review 8.pattern 9.session 10.meaningful 11.relearn 12.psychology 二、短语汉译英 1.forgetting curve 2.after 24 hours 3.two-thirds of 4.slow down 5.over time 6.make sense 7.in many sessions 8.find out 三、词形变换 1.meaningful 2.useful 3.helpful 4.powerful 5.successful 能力进阶 一、单句填空 1.tested 2.hours 3.helps 4.longer 5.hours 二、根据汉语意思完成句子 1.carried; out 2.nine; hours 3.two; thirds 4.sessions; at; once 5.Meaningful 三、句型转换 1.When; do 2.How; did 3.How; useful 4.Does; start 5.don't; remember 四、选词填空 1.curve 2.forget 3.review 4.meaningful 5.sessions 五、情景补全对话 答案：1.A 2.F 3.C 4.E 5.B；多余项：D 拓展提高 Passage1 任务一：1.B 2.C 任务二：3.T 4.F 任务三简答：5.It starts with a sharp drop. Passage2 任务一：1.B 2.A 任务二：3.F 4.T 任务三简答：5.Because the brain has time to store it. 任务四范文：The forgetting curve tells us that we forget very fast at first. So we should review new words in time. Here is my plan. On the first day, I learn twenty new words and review them that evening. On the second day, I review them again before I learn new ones. After a week, I test myself, and after a month, I review the difficult ones once more. I also study in short sessions, because the brain needs time to store information. If we follow the curve, we will remember much more with less time. 学科网（北京）股份有限公司 $
