1 . It is normal to feel a bit worried about exams, especially if you’re under pressure from school or family. Exam stress can cause you to feel nervous or depressed (沮丧的), and this might influence your sleeping or eating habits.

If you have any of these feelings or are worried that exam pressure is taking over your life, you are not alone. Here are some things you can do.

Firstly, let your trusted friends and family know if you’re having a hard time, so they can be there to support you, encourage you and offer a listening ear. You don’t have to go through (经历) this alone. Keeping it all in will only make things worse, so don’t be afraid to open up.

Secondly, think about all the practical support you need, and be honest with yourself about it. You are allowed to ask for help. Tell your teachers about your worries. They may have talked to lots of students who are going through similar things, so they can give you some helpful advice.

Thirdly, be kind to yourself. Think about all the things you have achieved so far. It can be helpful to write a list of all the things you like about yourself, and the things other people value about you, too.

What’s more, deal with pressure from your parents properly. If your parents put pressure on you, you can tell them what you feel able to achieve, and let them know that your expectations are different from theirs. You can also talk to a teacher you trust about the pressure you are under at home.

3 . We all know the dangers of fires. It’s good and necessary for a family to learn how to prepare for a fire. Here are some suggestions.

Put a smoke alarm in the house. Smoke from a fire causes the alarm to go off. The alarm makes a loud sound. The sound tells everyone to leave the house at once.

Make escape plans. We should know all the ways out of the house. If there is a fire, everyone follows the plan to get out. Part of the plan is to check all the windows to make sure they can be opened easily.

Buy fire extinguishers (灭火器) in the house. Everyone in the family should know how to use them.

Practice for a fire. We do fire practice because we teach children about fire safety. Everyone in the family should know the following fire rules:

★Don’t open a hot door! The fire can grow more quickly if you open the door.

★Stay close to the floor! Smoke can be more dangerous than fire. The best air is near the floor because smoke rises.

★What will you do if your hair or clothes start to burn? First, stop! Don’t run! The fire burns faster because of more air. Drop! Fall to the floor. Then roll! Turning over and over will make the fire go out.

There are many possible causes for fires. A wise family is ready for a fire all the time.

5 . A lot of people have the habit of reading on the toilet. But in some public restrooms in Shanghai, you won't be able to do that. If you spend more than fifteen minutes on the smart toilet there, a restroom worker will come to check on you.

According to reports, about 150 high-tech restrooms have been built in the city. Each toilet there has a sensor(传感器) that can check when a person sits on the toilet and how long he has spent sitting there. Besides, the sensor can also check the air quality inside the toilet and check the water level to save water. Beijing, Guangzhou and Shenzhen are also going to use smart toilets.

"I think it's okay with me because I don't think it's a good idea to read on the toilet," a 22-year-old young man said. However, some people aren't very happy with the smart toilet." This could be embarrassing for me. Since I was a little kid, I've always spent about half an hour on the toilet. It means a restroom worker would check on me twice. This makes me nervous." another person, Mr.Liu said.

In fact, the smart toilet is part of China's effort to use artificial intelligence(AI)(人工智能) in different areas of life. Now technology is being used almost everywhere. More than 700 cities in China have planned or are in the process of building smart infrastructure(基础设施). Our life is becoming much smarter and easier, isn't it?

7 . Sometimes vaccines（疫苗） do not provide lifetime immunity（免疫）. Some are only effective（有效）for a limited amount of time. In such cases， shots are necessary to maintain continuous vaccine protection. These shots are given at regular time. One vaccine， the flu （流感）vaccine， must be given every year. This is because there are many kinds of the flu.

A vaccine given in one year may provide protection against certain kinds of the flu virus， but when the next year’s flu season starts， vaccination against newer or different kinds may be required. Furthermore， flu vaccines do not provide protection for a lifetime. After as little as one year， protection may be far less than enough.

8 . Bullying（欺凌）can happen to anyone. A great many children around the world are bullied every year, but there are things that can be done to help

What is bullying?

Bullying is when someone makes you feel bad or hurts you again and again. Bullying can happen at school, out of school and online. Bullying includes:

·calling people mean（恶意的）names

·laughing at people

·telling lies about people

·taking someone's things without permission（允许）

·not letting someone play in a group

·hitting people.

What is cyberbullying?

Cyberbullying includes:

·sending bad messages online

·sharing photos online without permission

·not letting someone be part of an online group

·spreading lies online.

What can you do?

If someone is not kind to you, tell an adult that you know and like. For example, talk to a parent or a teacher.

If you get bad messages, don't reply.

You should save them and give them to your teacher, your family, or the police. Ask an adult for help. Don't share something before you make sure it is true. That will help stop the cyber bullying.

Talk to your parents or teacher or an adult if you see bullying or if you are worried about a friend.

Say sorry if you are not kind to someone. You can write a message or talk to the person. And always remember: think about how to be kind in the future.

9 . There have been many great inventions that changed the way we live. The first great invention was one that is still very important today—the wheel. This made it easier to carry heavy things.

Then in the early 1800’s the world started to change. There was little unknown land left in the world. People didn’t have to explore(探测) much anymore. They began to work to make life better.

In the second half of the 19th century, many great inventions were made. Among them were the camera, the light and the radio. These all became a big part of our life today.

The first part of the 20th century saw more great inventions：the helicopter in1907, movies with sound in 1923. the computer in 1927, and jet planes in 1930. This was also a time when a new material was first made.   Nylon（尼龙）came in 1937. It changed the kind of clothes people wear.   

By this time most people had a very good life, and man has a desire to explore again. The world was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space.   

New inventions will someday allow us to do things we have never yet dreamed of.
