Maybe it's the way the teacher lectures that makes it hard for you to accept. Just transfer your interest to study there. How to do it specifically, I suggest the following:

1。 Preview before class, tick off what you don't understand, and the teacher will naturally listen attentively in class.

2。 Review after class, systematically understand the knowledge you have learned, and ask teachers or classmates for advice if you don't understand the knowledge.

3。 If the knowledge in the textbook is not difficult to accept, you can try to do extracurricular exercises, which can enrich your knowledge, make yourself confident in class and raise your head, so that you will listen carefully when the teacher lectures and answer the teacher's questions quickly after asking questions.

4。 You said you often want to sleep. I suggest you drink tea every day. Tea can refresh the brain and make the brain clear.

5。 Buy some novels to read and understand the author's thoughts and feelings. Or watch the growth stories of celebrities and understand their feelings and thoughts at that time.

As long as you make up your mind to study hard, no matter how big the difficulties and setbacks are, you can overcome them. Come on, study, the future must be bright.

Sleeping in class is a very contradictory problem. First of all, it will affect the quality of your whole class, but if you don't sleep, you will feel sleepy and can't listen well. So, you'd better keep enough sleep.

If it still doesn't work, it's like a teacher applying to stand for a while and listen carefully for a while. I don't think you should fall asleep standing until you wake up. That's how I got here in high school. Very effective.

Another good idea is that you can force yourself not to be distracted and sleepy.

But I think it is most important to adjust my usual sleep. . .

It seems that every student has had this experience.

At first, there was nothing to be sleepy about, and most of those who could stay up late were slowly practiced.

Yes

When we took the senior high school entrance examination, no one slept more than five hours a day, and they often had to.

Stay up late for several days.

Now in high school, students don't sleep until 12.

Yes, I sleep for two or three hours every day.

I guess you're not old enough to go to high school, or you're not old enough to be a sophomore.

So you don't have to stay up too late like I said.

Drink a little coffee when you are sleepy. If you don't drink it often, drink a pack of coffee.

Long-term persistence.

But don't drink it often, it will be ineffective if you drink it often. I think it's best not to take medicine, but ...

You should sleep for a while, and don't harm your health.

This kind of thing will eventually depend on your own perseverance and get used to it.

It's no use relying on others.

1. Apply to the teacher: stand in class.

Don't stare at the teacher.

3. Take the initiative to think about all kinds of questions. Even if there are no questions, ask yourself why and answer them yourself.

... looking for ... your weekly diary. ...

There used to be a phenomenon that bothered me and made me very upset-it was difficult to concentrate in class.

Every time I attend a class that doesn't appeal to me, but is beneficial to Chinese, mathematics and geography, I still listen to the teacher at first, but I soon lose my mind, either staring at a book and trying to write down my thoughts or chatting with my classmates next to me.

Especially in the afternoon, I don't know where my mental changes are. Although in most cases, I have changed a pillow to support my chin and lead me into a continuous sleeping environment, I still can't really fall asleep with my last perseverance. But even so, I still can't hear any classes. I know that if it lasts for a long time, it will definitely seriously affect my study.

In order to arouse my enthusiasm in the classroom, I really spent a lot of time and finally figured out the key, which is to actively participate in the classroom. So what are the conditions for participating in the class? It's actually quite simple. First of all, raise your hand to speak, but if you don't know the answer, try to find it. In addition to speaking actively, there is another point, which is also the most important point-force yourself to follow the teacher's ideas, do what the teacher asks you to do in the most positive way, and respond to what the teacher says in the most positive way. If all this can be done, I believe it will be difficult to be distracted again.

Good habits can make our life orderly, and good methods can make us get better results. To get a good method, we need to keep exploring, which is the best way to get the method and solve the problem.

Maybe this weekly diary is not very good. . . But I still hope to inspire you, hehe.

There are many reasons for dozing off in class: only by finding the reason can we prescribe the right medicine.

First, are you not interested in learning? If so, everyone will doze off on things that are not of interest. Then you should cultivate your interest in learning. You shouldn't doze off in all subjects. There's always a subject you like that won't be like this. It shows that you are interested in this subject and cultivated your interest. It's easy to say, but you must find your own way, such as liberal arts, which I didn't like before. You can arouse your interest by reading related extracurricular books that you are interested in. There is also the feeling of finding success. If you are good at a certain subject, I believe you will feel very happy if you want to take this course. This will form a virtuous circle.

Second, it may be your biological clock, which is suitable for studying at night. Then you should make full use of your best study time.

Third, is it because you are too tired to play during recess, so you are sleepy in class? Then you can just rearrange yourself.

Fourth, is it not good to stay up too late at night? You must ensure enough sleep. If you can't finish your homework at night, you can put it in the morning, but it varies from person to person. Since you want to change the state of dozing off in class, I believe you can.

Give you a very scientific explanation: people's sleep cycle is generally about 2 hours, and the total sleep time should be an integer multiple of this cycle, otherwise they will feel very tired no matter how long they sleep ~ ~ On the contrary, if they sleep only for two hours, the effect will be much better than sleeping 1 1 hour ~ You can try it ~ ~

Very scientific explanation ~ ~

If time is limited, take a nap on your stomach and wake up in 10 minutes, and your spirit will be fine.

Don't miss the woodcutter when sharpening the knife ~ pay attention to sleep at ordinary times ~
