But I still clearly remember the difficult problem I failed to solve!” Many students have this kind of conversation in daily life. This strange memory rule has a special scientific name: the Zeigarnik Effect(蔡加尼克效应). The Zeigarnik Effect is a common psychological phenomenon(现象). It was found by a famous psychologist named Bluma Zeigarnik. After many simple experiments, she found a funny rule about human memory. People are much more likely to remember unfinished tasks than completed ones. ★ Our brain has a special inner drive to finish every task we start. When a task is not done, the brain will keep this information active in our mind. It reminds us to finish the work sooner or later. However, once we complete a task completely, things change quickly. Our brain will think the task is no longer useful. It will stop focusing on it and slowly clear the memory. This explains why we easily forget finished homework, finished exams and completed plans. This effect also appears in many small daily situations. For example, you may forget all the videos you have watched, but always remember the stories you have not finished reading. Many people collect learning resources but never use them. The “collection” makes the brain feel the task is done, so people finally forget these resources completely. The Zeigarnik Effect teaches us a good lesson. If we want to remember knowledge well, we should not only finish tasks simply. We need to review and use knowledge regularly. Only in this way can we turn short-term memory into long-term knowledge and make progress in our study. ( ) 1. What writing skill does the writer use at the beginning of the passage? A.Listing numbers B.Showing a dialogue C.Giving suggestions D.Making comparisons ( ) 2. Which sentence can be put in ★ ? A.This effect appears everywhere in daily life. B.Few students know this special memory rule. C.We can use this effect to improve our memory. D.There is a simple reason behind this effect. ( ) 3. Why can we remember unfinished tasks better according to the text? A.We spend more time on unfinished tasks than finished ones B.Unfinished tasks are always much easier for us to understand C.The brain keeps the information active to remind us to finish them D.People usually write down unfinished tasks on notebooks ( ) 4. Which example shows the Zeigarnik Effect in daily life? A.You forget learning resources you just collected and never use B.You keep all your finished exam papers in your schoolbag C.You quickly forget the novel you haven’t finished reading D.You can remember all videos you watched in your free time ( ) 5. What is the main idea of the passage? A.How to finish all school tasks quickly. B.The introduction and influence of the Zeigarnik Effect. C.Good ways to improve short-term memory. D.The brain’s different ways to store videos and stories. 【拓展提升】 六、综合填空。 阅读下面短文，根据上下文或括号内单词等提示，在空白处填入适当的单词或括号内单词的适当形式。 Newspapers are 1 important part of people’s daily life.

It reminds us to finish the work sooner or later. 对应C选项。A、B、D原文均无相关表述。 4. 细节理解题。原文第五段举例：很多人收藏学习资料却从不使用，收藏行为让大脑判定任务完成，最后彻底遗忘资料，与A选项匹配。B文中无保存试卷的内容；C未读完的小说我们会记得，而非遗忘；D看过的视频容易忘记，三项均与原文相反。 5. 主旨大意题。全文先用对话引入蔡加尼克效应，介绍发现者、形成原理、生活实例，最后说明该效应对学习的启示，整体围绕蔡加尼克效应展开介绍。A快速完成任务、C提升短时记忆、D大脑储存视频故事，均只是文章局部内容，不能概括全文。 六、综合填空。 1. an 2. development 3. on 4. earliest 5. greatly 6. products 7. covering 8. to know 9. has changed 10. Although/Though 解析： 1. important以元音音素开头，an important part 一个重要组成部分。 2. 介词of后接名词，develop动词变为名词development，history of development 发展历史。 3. 固定搭配on silk and paper 在丝绸和纸张上。 4. 定冠词the后用形容词最高级，the earliest form 最早的形式。 5. 副词修饰动词improved，great形容词改为副词greatly（极大地）。 6. 主语Newspapers是复数，对应表语用可数名词复数products（产品）。 7. 本句已有谓语came out，现在分词covering作伴随状语，表示报纸涵盖各类新闻。 8. 固定结构the way for sb. to do sth. 人们了解世界的途径，不定式作后置定语。 9. In modern times（现如今）为现在完成时标志，technology单数，用has changed，表示数字技术已经改变人们生活。 10. 前后两句存在让步关系：虽然传统报纸不如从前流行，但依然重要。although/though引导让步状语从句。 学科网（北京）股份有限公司 $
