Be sure to have breakfast in the morning, otherwise your blood sugar will be too low, you will feel dizzy and have poor memory, which will affect your learning effect. Observe the principle of eating well in the morning, eating well in the middle and eating less in the evening. Morning is very important, and balanced nutrition is a good start to the day. You can choose flour with milk or soybean milk, and add a fruit and a small cake between two classes; Noon is important. According to what you said, you should take rice as the staple food and go to a clean and better place for lunch, because the nutrition in the food can provide you with the energy you need for studying in the afternoon. Remember not to eat non-staple food (such as biscuits, bread, canned food, etc.). These foods contain a lot of additives and preservatives, which is very bad for you who are learning and growing up now. It is ok to add meals between meals, but when you get home at night, you should eat more fruits and vegetables, supplement vitamins, clear your intestines, and eat everything without partial eclipse. Adding a cup of yogurt after dinner at night will not only help digestion, but also help people absorb calcium more easily than milk (it is best to drink yogurt between half an hour and two hours after meals). More importantly, just play chess and relax, because stress will make you stupid. Say something beside the point,
In fact, there is no need to stay up all night studying. You study in your daily life. If you want to learn English well, you should watch more original movies and apply the words you have learned to your daily life. It's better than staying up late to hurt yourself. This is also the method my teacher told me, because it is better to remember it anyway. I'll tell you another memory method, that is, to convert the objects memorized by the left brain into the graphic memory of the right brain, so that you can remember them easily and firmly.
Finally, I wish you progress in your study!
