Scientists have discovered some interesting facts about memory. First, there are two types of memory: short-term memory and long-term memory. Short-term memory can hold only a few things for a short time — usually less than 30 seconds. Long-term memory can store information for days, months, or even a whole lifetime. Second, we remember things better when we connect new information with old information. For example, if you want to remember a new word, you can connect it with a picture or a story. Third, emotions play an important role in memory. We often remember happy or sad events more clearly than ordinary daily activities. Fourth, sleep is very important for memory. During sleep, our brain processes and stores the information we learned during the day. That is why students should get enough sleep before exams. Finally, practice makes perfect. The more we use our memory, the stronger it becomes. ( ) 1. According to the passage, our memory is like ______. A. a computer B. a muscle C. a picture D. a book ( ) 2. How long can short-term memory usually hold information? A. For a whole day. B. For less than 30 seconds. C. For a week. D. For a year. ( ) 3.

( ) 4. What does the passage say about sleep? A. Sleep is a waste of time. B. Sleep makes us forget things. C. Sleep helps the brain store information. D. Sleep is not important for memory. ( ) 5. What is the main idea of the passage? A. Memory is not important.  B. Everyone has a poor memory. C. We can improve our memory with the right methods.  D. Only old people have memory problems. （六）书面表达（15分） 题目：An Unforgettable Memory 要点： 1. 描述一件你难忘的事情（时间、地点、人物、经过）； 2. 为什么这件事对你来说如此难忘（用宾语从句表达，如 I think that... / I believe that...）； 3. 这件事对你的影响或启发。 要求： 词数80词左右； 包含至少两个宾语从句； 条理清晰，书写工整。 解析版答案 边讲边练1 —— 词形转换 答案速查： 1. memory 2. unforgettable 3. memories 4. making 5. deeply 详细解析： 1. memory —— 冠词 a 后接可数名词单数，have a good memory 表示“记忆力好”，memorize 的名词形式为 memory。 2. unforgettable —— 冠词 an 后接形容词修饰 experience，表示“令人难忘的”，forget 加前缀 un- 和后缀 -able 变 unforgettable。 3. memories —— 形容词 happy 后接名词，且为复数概念（童年的快乐记忆），memory 变 memories。 4. making —— 介词 by 后接动名词，make 变 making。 5. deeply —— 修饰动词 believe，用副词形式，deep 变 deeply。 边讲边练2 —— 短语填空 答案速查： 1. reminds me of 2. keep in mind 3.

I remember that the sea was blue and the sunshine was warm. We built sandcastles, swam in the sea, and took many photos together. I think that this day is so memorable because it was the last time our whole family traveled together before my sister went to study abroad. The photos on the wall always remind me of that happy day. I believe that family time is the most valuable thing in life, and I will always keep this memory in my heart. 学科网（北京）股份有限公司 $
