Unit 4 Section A 2a-2d 课件 2026-2027学年人教版英语九年级上册

IT seems that all of you have some memory problems. I think you all need to come to my lecture and learn how to improve your memory. Would you like to come to my lecture? Okay, let's all be there. If you stress that because you have a bad memory, I am going to get you ways to improve your memory with these good habits. The first way to improve your memory with a good habit is getting enough sleep. You've heard that said a million times, but it's so true. Without a good night sleep, you're not going to be able to remember the next day. The next step is to drink plenty of water. A dehydrated ted brain is a brain that won't be able to focus. So that's why drinking plenty of water is so important. The next one is exercise. A two thousand fourteen harvard health letter said the exercise helps the memory in both direct in indirect ways. Now, salt plays an important part of your memory. A lack of salt is actually gonna hurt your memory. But if you go overboard and have too much solve, that is bad for your memory. And IT has even been linked to all time's disease. Stress is worth out question the worst intimate to your memory. Think about a time in your life when you are stressed out. You are going to a stressful period in your life. Your memory was probably horrible. Moving on, avoid excessive sugar. The hippo campus is a part of your brain that is very sensitive to sugar. The avoid excessive alcohol for scientific reasons only. I taken alcohol and tried to memorize the same time. I don't have to tell you the results. You know the results. The mind remembers what IT sees. So if you want to start remembering stuff, you have to be able to turn this into a picture, and you have to be able to see IT. Professor, I don't quite understand what you said about linking knowledge. Well, knowledge like a chain, and new knowledge is best remembered by linking IT with old knowledge. The more links you create, the more you remember. Professor, I often get some words mixed up like kitchen and chicken. to details, study how they are different from each other. You can also create a picture for each word in your mind. Hello, professor. Could you tell me why IT is much easier to forget things, to buy them, to forget how to ride a bike. Scientists are still working on this mystery. For one thing, the memory of how to ride a bike is probably stored in a more stable area of our brain. There are so many mysteries . about our brain exactly. And at your age, your brain is developing fast. So put IT to good use. If you read enough, there is a similarity between things that make IT easy, because this thing is like the other thing. If you would have a broad framework, then then you have a place to put everything. If you want to learn science, reading the history of scientists and the story of scientists about when they were confused, and what tools are, insights allow them to make the progress they make. So you have the time line, you have the map, you have the branches of science and what's known and what's certain. So incremental knowledge is so much easier her to uh, maintain in a rich way. Then you know the first time know somebody know was telling you about rome. Why am I reading about rome and reading about queen Victoria at first? That is very dawn team. But then if you get the kind of scope, then all these, these pieces fit in toys. Fun to say. Okay, this is where this longs and all this, this contradicts something I knew before. And i'd Better looked that up. I Better figured out, you know, really bothers you when you read things. And there are some inconsistency, if you take a chess board and randomly place the pieces and ask a chess person to memorized that, they can't do IT. Because everything about chess position is about the logic of how things developed. So if you show my position, illogical, learn, correct, you would never get to their encoding systems. M, set up啊。To absorb that. I spoke with bill gates . for thirty minutes the other day. Court members can access the entire conversation on our website, and they can also click on the membership exclusive link new members, so people are not membership to help but want to give them a try, can click on that same membership link to sign up for a free trial. What you'll get is other exclusive video. You'll get this conversation with bill gates and you'll get our dep report on areas of disruption in the global economy. We hope you'll give them a try.

Don't worry, next week we'll invite a special guest to our school, professor Green, a famous memory scientist. He will give us a memory. Q. Behold the human brain, its lumpy landscape, visibly split into a left and right side. This structure has inspired one of the most pervasive ideas about the brain, that the left side controls logic and the right creativity. And yet this is a myth unsupported by scientific evidence. So how did this misleading idea come about? And what does IT get wrong? It's true that the brain has a right in the left side. This is most apparent with the outer layer or the cortex. Internal regions like the stroke item, hypothalamus, filament and brain appear to be made from continuous tissue, but in fact, they're also organized with left and right sides. The left in the right sides of the brain do control different body functions such as movement and sight. The brain's right side controls the motion of the left ARM and leg, and vice versa. The visual system is even more complex. Each I has a left and right visual field. Both left visual fields are sent to the right side of the brain, and both right fields are sent to the left side, so the brain uses both sides to make a complete image of the world. Scientists don't know for sure why we have that crossing over. One theory is that began soon after animals developed more complex nervous systems because I gave the survival advantage of quicker reflexes. If an animal sees a predator coming from its left side, it's best off escaping to the right. So we can say that vision and movement control are two systems that rely on this left right structure. But problems arise when we also extend that idea to logic and creativity. This misconception began in the mid eighteen hundreds when two neurologists, broker and warney, examined patients who had problems communicating due to injuries. The researchers found damage to the patients left temporal loads, so they suggested that language is controlled by the left side of the brain that captured the popular imagination. Author robbert Lewis Stevenson then introduced the idea of a logical left hemisphere competing with an emotional right hemisphere represented by his characters doctor, jackal and mr. hide. But this idea didn't hold up when doctors and scientists examined patients who were missing a hemisphere here or had their two hemispheres separated. These patients showed a complete range of behaviors, both logical and creative. Later research showed that one side of the brain is more active than the other. For some functions, language is more localized to the left and attention to the right. So one side of the brain may do more work, but this varies by system rather than by person. There isn't any evidence to suggest that individuals have dominant size of the brain, or to support the idea of a left right split between logic and creativity. Some people may be particularly logical or creative, but that has nothing to do with the size of their brains, and even the idea of a logic and creativity being at odds with each other doesn't hold up well. Solving complex math problems requires inspired creativity, and many viBrant works of art have intricate logical frameworks. Almost every feet of creativity and logic Carries the mark of the whole brain, functioning as one.
