Students usually have to spend a lot of time learning knowledge, but the learning outcome cannot always meet what we expect. 【小题1】 Here, let’s try Feynman’s learning method.

        As the name suggests, it was proposed by a Nobel Prize winner Richard Feynman (理查德•费曼). It is an effective (有效的). 【小题2】

First of all, choose a concept (概念) as your learning aim. Read the material and try to understand it.

【小题3】 For example, suppose you are trying to explain the concept to a 5-year-old boy. You use simple language in order to make him fully understand it.

If you have trouble explaining it clearly, then come to the third step. 【小题4】 Explain it to the boy bit by bit in your own words until he completely understands it.

Finally, you should be able to answer questions about the concept. 【小题5】

        Feynman thinks that understanding is more important than memorizing. His learning method encourages students to think deeply and solve problems with their own understanding.

When you are sad, you need to find ways to deal with your sadness. When you learn how to deal with your sadness, you’ll find your own happiness.

Speak about your sadness. You don’t have to tell everybody everything, but it is nice to talk to friends or family members about your feelings. You may not need him or her to say a word; just having someone listen to you is sometimes enough.

Having a bloody nose can make some people nervous, but in most cases, nosebleeds are easy to stop and rarely (很少) serious. Around 60%of people will experience a bloody nose in their lifetime. Nosebleeds are most common in children from 2 to 10 years old and in adults aged 50 to 80.

Common causes of nosebleeds include dry air and injuries to the nose or other parts of the head. Blowing your nose too often when you have a cold can also lead to nosebleeds. You probably already know how to stop a bloody nose right away, but it’s important to do it properly and safely.

Always sit up straight when your nose is bleeding, and never lie on your back. One of the biggest mistakes in first aid is that you should lean (倾斜) back with a bloody nose, but the best thing to do is lean forward. The blood needs to go somewhere, and if the person leans back or lies down, it will most likely go down his throat, possibly causing choking. And try not to put tissues (纸巾) into your nose.

Pinching (捏住) the nose properly stops or slows the bleeding. Hold the nose for at least five minutes. Do not let go to check for bleeding until at least the first five minutes are up. If you can, keep the pressure on for longer, After five minutes, see if the bleeding has stopped. If not, pinch again, but keep it up for 10 minutes this time. Remember: Don’t let go to check for bleeding until the 10 minutes are up. If bleeding doesn’t stop after that time, repeat it for another 10 minutes if necessary.

Avoid activities such as heavy lifting, blowing or picking your nose for a day after the nosebleed has stopped. Remember that if you can’t stop the nosebleed with these methods, see a doctor immediately.
