The human brain weighs about 1.4 kilograms, but it can hold much more information than most computers. However, there is another difference between human brains and computers. Computers don’t forget information they are given, but humans often do. No one remembers everything, and luckily we don’t usually have to. But everyone can improve their memories if they want to. Here are some suggestions.
________ For example, if you meet someone who says “Hi! I’m Carlos”, don’t just say “Hello”. Repeat the person’s name and say “Hello, Carlos”.
________ For example, it’s hard to remember 109244153. But if you break it into three parts—109/244/153, it will become easier.
________ Writing it down will help you keep it in mind longer, especially when memorizing formulas (公式) or facts.
________ If you bring what you’ve learned back to your mind, it’ll become easier to remember. For example, before you go to sleep, it’s a good idea to review the new things you’ve learned that day.
________ It is always easier to remember things through discussions. You can have a discussion about what’s right or wrong, and it will lead to the right answer. All of the suggestions are helpful. If you follow them, you can improve your memory.

If you were born after 1995, then you won’t remember life before the Internet. Being connected through smartphones and social media is now just a part of growing up for many teenagers. Most of them have many nice experiences online, but there are risks as well.
Social media allows teens to communicate with others and build social networks. These networks can provide teens with valuable support. Teens also use social media for entertainment and self-expression. The platforms such as QQ, WeChat and Weibo, can help teens become aware of the latest events, allow them to communicate across distance and teach them all kinds of subjects, including how to behave well. A wide social network might even help teens avoid social worries.
However, social media use can also do harm to teens. The risks might be connected with how much social media teens use. A 2019 study of more than 6,500 teens in the U.S. found that those who spent more than three hours a day using social media might be at higher risk for mental (心理的) health problems. And an older study on students showed that the more time the students spent going out with their friends, the happier they might feel. Here are tips for you to make good use of social media:
● Discuss your social media habits with your parents. Ask your parents how he or she is using social media and how it makes him or her feel.
● Talk to your parents about how to avoid letting social media influence your activities, sleep, meals or homework. Keep smartphones out of your bedrooms and avoid electronic media use before bedtime.
● Ask your parents what is proper and safe to share on the social media. Have more face-to-face contact with your friends. This is especially important for teens who are weak to social worries.
