2 . The human brain weighs about 1.4 kilograms, but it can hold much more information than most computers. However, there is another difference between humans and computers.     1     No one remembers everything, and luckily we don’t usually have to. But everyone can improve their memory if they want to. Here are some suggestions.

◆Try to use new information as soon as possible. For example, if you meet someone who says “Hi! I’m Carlos,” don’t just say “Hello.” Repeat the person’s name. Say “Hello, Carlos.”

◆    2     For example, it’s hard to memorize 109244153. But if you break it into three parts—109/244/153 —it becomes easier.

◆Write out what you need to remember over and over again. This will help you keep it in mind longer, especially for memorizing formulas (公式) or facts.

◆Always review information. If you bring what you’ve learned back to your mind, they become easier to remember.     3    

◆Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what’s right and what’s wrong, and it will lead to the right answer.

◆Never tell yourself that you have a bad memory.     4     And everyone’s memory gets better if they use it often enough.

All of the suggestions are helpful.     5    

When it comes to fire, people are always scared because no one wants to get hurt.     1     Here is some advice on how to save yourself in a fire.

When a fire breaks out in your building, you should go outside as quickly as possible.     2     You should stay low to the ground, because smoke naturally rises. And remember to cover your nose and mouth on the way.

If you’re in a room and it’s already too late to get out, close the door first. Then block the cracks (堵住裂缝) around the door with some wet clothes.     3     At the same time, open the windows and shout for help.

If your clothes catch fire, don’t run!     4     Then you should lie down on the ground, cover your face with your hands and roll (翻滚). This will cut off the air and put out the fire.

It’s useful to get to know these pieces of advice.     5     Having a fire drill (训练) at home makes everyone able to see how they will do in a real fire.

6 . China is an old country with a long history and special culture. As time passes by, Chinese people's clothing changes, too. There are many types of costume in Chinese history, such as the cheongsam and Chinese Tang costume.     1     Sometimes you can see foreigners wearing them. Nowadays more and more people begin to pay attention to another costume-Hanfu.

Hanfu was the traditional clothing of ancient (古代的) Chinese people.     2     Ancient Chinese people regarded Hanfu as a very important part of their culture. They wore Hanfu during some special occasions, like the Spring Festival.     3     According to the legend (传说), his wife was the first to know how to make silk and taught others to make Hanfu with silk.

Since Shang Dynasty, Hanfu has changed.     4     For example, Hanfu doesn’t have buttons (扣子). Instead, it has a sash (腰带) for people to keep clothes closed. And people usually overlap (使重叠) the right side of the clothes with the left side.

    5     You can see them wearing Hanfu on different occasions, like on their birthdays or National Day.

When faced with a difficult exam, you might be worried about whether you have done well or not. In order to experience positive (积极的) feelings, you feel like working harder to get a good grade.

Charles Darwin was one of the earliest scientists to study feelings. He believed that feelings allow both humans and animals to live a peaceful life. For example, if you meet a barking (狂吠的) dog, it clearly shows that the animal is angry, driving you to stay back.

    4    

When you communicate with others, it is important to understand how they are feelings in the moment through their facial expressions and body language. This allows you to build deeper and more meaningful relationships with others.

    5    

Feelings have a great influence on the decisions you make, from what you have for breakfast to what job you choose to take. They may also help you make faster decisions.

Cindy was eight years old and lived with her parents in California. One day, her parents told her that they would leave California in a week and move to Florida     1    

A week later, after they moved to Florida,     2     The teacher said, “Welcome to our school, Cindy. Let me tell you what we do in our second-grade class.     3     After that, we do math. Then we go out to have a long rest for outdoor activities. We eat lunch at eleven o’clock. Then we have story time. After story time, we have science.     4     There you can work on the computer, play a game, or read a book. Next, we have spelling (写字课). Finally, we go to music and art classes for the last hour of the day. Here is a time list of the subjects and school activities for you. There is some other information in it.     5     I’m sure your new classmates will be glad to see you, too.”

10 . Fights at school sometimes happen.     1     Here are some ideas.

Keep calm (镇静的).

Sometimes, you feel so angry that you really want to teach somebody a lesson. But being angry and having a fight can’t solve problems.     2     In the school, anyone who joins in a fight will be punished (惩罚). There are no winners in a fight.

Shout loudly.

If you know someone is about to attack (攻击) you, say “stop” in a loud voice before walking away.     3     If the person doesn’t stop, cry for help by calling out the teachers who are in the nearest office.

Learn to refuse.

    4     Learn to say no. Helping him fight is not helpful to him. Try to ask him to give it up if you really want to give him a hand.     5     Then, try to find out why he wants to fight and help him find a right way to deal with the problem.
