Knowledge is like a chain, and new knowledge is best remembered by linking it with old knowledge. The more links you create, the more you remember. 2.Why do we get some words mixed up? Pay attention to details. Study how they are different from each other. You can also create a picture for each word in your mind. 3.Why is riding a bike not so easy to forget?

How can you link new knowledge with old knowledge? Give an example. 1.Review old knowledge before class. 2.Find connection points between new and old knowledge. 3.Apply new and old knowledge through homework and exercises. 2d Work in groups. Discuss the questions. We can compare new knowledge with what we have already learned. We can also connect new words or rules to our old notes, old sentences or real‑life experiences. For example, when we learn the new English word unforgettable, we can link it with the old word forget. We already know “forget” means to fail to remember something. So “un‑” means “not”, and “‑able” means “can be”. Then we can work out the meaning of unforgettable = cannot be forgotten. It is a good way to connect new information with our old knowledge. First, we can find similarities and differences between new points and what we have learnt before. We can also put new‑learned things into old sentences or mind maps. Here is an example. When we meet the new verb invent, we can connect it with the old word invention. We have already known “invention” is a noun for something created. Then we learn that “invent” is its verb form, which means to create something new. By linking them together, we can remember both words much better. 3. Why should students put their brain to good use? What is your opinion? First of all, the brain works like a muscle. It will become more powerful if we keep using it. If we seldom use it, our memory may become poorer. Besides, using our brain actively helps us connect new‑learned knowledge with old knowledge. In this way, we can remember information for a longer time and get better grades at school. What’s more, putting our brain to good use encourages us to think independently. We will not only memorize facts, but also try to understand them. So students should try different ways to train their brain, such as doing puzzles, drawing mind maps and reviewing lessons in time.
