Are they useful? I usually take notes of key points when I study, and I also use mind maps to organize information. These techniques are really useful—they help me remember things more easily and transfer information to my long-term memory quickly. I often review what I've learned at proper intervals and try to recall knowledge without looking at my books. I also divide difficult information into small parts to memorize. These techniques are quite useful — they help me fight against forgetting and move information into my long‑term memory. Skim through the text and select the correct answer. 1. What is the type of this passage? A. A news report. B. An expository article.（说明文） C. A story. D. A poem. 2. What is the main idea of the text? A.

Read the text and answer the questions. How to Boost Your Memory Would you like to improve your memory? To start with, it is important to understand how memory works. There are two main kinds of memory: short-term memory and long-term memory. Short-term memory helps you remember things that you may only need for a short time, like phone numbers when you need to make a phone call. Long-term memory is the ability to remember things for days, years, or even a lifetime. So the real question is: How do you make sure what you learn enters your long-term memory? By using some clever memory techniques and leading a healthy life, you will see some great results. Let's take a look. Read the text and answer the questions. First, pay attention. However, you might fail to remember all the details. So, try taking notes by writing down key points. After all, it is easier to remember a summary than every word in a passage. Second, use it or lose it. The more you review what you learn, the more likely you will remember it. However, you should not wear out your brain. Try studying for 40 minutes, and then take a break. You can also review information by discussing it with others or by teaching others. A third way is to make use of your senses. Create images by using tables, graphs, and mind maps to organize information. You can also create a story with information and view it in your mind like a film. In addition, make use of your other senses. For example, Read the text and answer the questions. listening to recorded information can be very effective. Last but not least, boost your memory by staying healthy. Sleep well. While you sleep, your brain organizes your memories. Bad sleep makes it harder for new information to enter your long-term memory. Eat well. Your brain needs food like an engine needs fuel. Healthy food and drink will help your brain work much better. Exercise. A healthy and active body boosts both your memory and your mind. Exercise can also reduce stress and anxiety. Many more memory techniques can be found in books or online. Try some different methods to see which ones work best for you. You are sure to improve your memory! Read the text and answer the questions. 1.

Introduction Body Conclusion It introduces two types of memory and raises the question of how to turn learned knowledge into long-term memory. It offers four practical suggestions about memory skills and healthy lifestyles to improve our memory. It advises readers to try different methods and find the most suitable ways to boost their memory. What kind of memory is needed for these tasks? Write S for short-term memory or L for long-term memory. ________ 1. You need to remember what you are going to say in a speech next week. ________ 2. You need to remember a new friend's name. ________ 3. You need to remember an address until you find a piece of paper to write it down. ________ 4. You need to remember the password to your online bank account. L L S L Read again and complete the mind map. Use it or lose it Pay attention Ways to improve your memory take notes; write down key points review what you learn; take a break after studying for 40 minutes; discuss information with others or teach others Use senses create images; create a story; make use of other senses Stay healthy sleep well; eat well; exercise Read the text carefully and select the correct answer. 1. According to Paragraph 3, why do we take notes of key points? A. To copy every word in the passage. B. To make it easier to remember a summary. C. To finish homework more quickly. D. To develop our writing skills. 2. Which of the following is NOT mentioned as a way to review information? A. Discussing knowledge with other people. B. Teaching what you learn to others. C. Keeping studying for hours without rest. D. Reviewing what you have learned often. Read the text carefully and select the correct answer. 3. What can we learn from the part about senses? A. We should only use our eyes to memorize things. B. Mind maps can help us organize information. C. Watching films is the best way to improve memory. D. Recorded information is useless for memory. 4. What will happen if we don't get enough sleep? A. New information is hard to become long-term memory. B. Our brain will organize memories faster. C. We will remember things much better. D. Short-term memory will disappear at once. Think and Share. What does the saying “use it or lose it” mean in this text? In the text, “use it or lose it” means we need to review our knowledge regularly. If we seldom go over what we have learned, we will gradually forget it. But frequent review helps information stay in our memory. For example, after learning new English words, I should review them from time to time. If I never use or review these words, I will forget them soon. Besides, we should also take proper breaks while reviewing, so that we won't make our brains too tired. Think and Share. Summarize these healthy habits from the article. Which habit do you think is the most helpful for you? Why? Three healthy habits are mentioned in the text. First, we need to sleep well. During sleep, our brain organizes memories. Poor sleep stops new information from turning into long-term memory. Second, we should eat well. Healthy food provides energy for our brain, just like fuel for an engine. Third, taking exercise is also important. Active bodies improve our memory and thinking, and exercise helps us reduce stress and anxiety. As for me, sleeping well is the most helpful. When I get enough sleep, I can focus better in class and remember more knowledge. If I stay up late, my brain will work slowly and I can hardly memorize new things.
