In the USA, each year, students take part in a kind of competition called the Science Olympiad.

    It has a lot of different events. Students go there to show how much they know about the science of music, biology, chemistry and others. My best event is forestry.

    The big day had come at last! First, I went to watch the tower building competition. That’s when students build small towers and put heavy things on top of them. They hope they can hold them up. One of my schoolmates was putting things on her tower. She was nervous, and in the end it was too heavy for her tower to hold them—it broke! I felt bad for her.

    After lunch, I helped some teammates with their events. One was geography, and the other was history. I don’t know much about those things, so I just watched my teammates do most of the work.

    At last, it was time for my favorite event—forestry. The rules were easy. We had to look at more than 40 different kinds of leaves and find out which plants they were from. We also had to answer some questions about the uses of each leaf. I knew almost all of the leaves and could answer most of the questions. I had spent more than a month studying on the Internet to get ready. At the end, it was time for the awards, I was nervous, because the forestry awards were last. We won second place in the whole state! A nice man gave me a medal and smiled at me.

Young children don’t have the skills or knowledge to stay safe in heavy traffic. The following tips（忠告）will be helpful for you to keep your children safe in heavy traffic.

Children learn about road safety by watching others. As parents, make sure that you always set good examples. Your children will follow you and think it’s OK to do like you.

Teach your children to pay attention to traffic lights when you cross the road together with them. This helps them understand when it’s safe to cross. Make sure that you walk between your children and traffic, and hold their hands all the time.

When your children are a little older, you can start to tell them the importance of traffic knowledge. ①Let them start to understand the reasons why they need to be so careful. Talk with them about road signs and traffic rules.

Ask your children to play in a safe place. Never let them ride bikes on the road ___②___ an adult present (在场) at rush hour.

The most important thing you can do is to keep your children from getting hurt，so parents encourage them to follow traffic rules. After knowing about traffic rules, they’ll volunteer to obey them. In this way, they’ll be careful enough to keep themselves away from danger.

Many people run for exercise. But what will you do if you are not a "born" runner or jogger (慢跑者)? You may still want a kind of exercise that’s inexpensive and easy to do. Why not try walking?

Walking requires no special equipment (装备). It is a kind of exercise that almost any normal, healthy person can do. Walking is good for your health like jogging or running; it will just take longer. Jogging and running make your heart work harder than walking. They also put more stress on your legs and feet than walking does.

The problem with walking is that most people don’t take it seriously. But there’s a big difference between serious walking and the walking that most of us do. Walking, like jogging, should have a steady and continuous motion (稳健而持续的动作).

If you want to get your exercise by walking, you need to have your own walking plan. After all, runners and joggers set goals for themselves. Walkers need goals, too. You also need to set a course to walk. Start by walking about 15~30 minutes a day. Increase your time and distance (距离) slowly. And try increasing your walking speed little by little.

If you prefer to jog or run, follow the same advice. Start off slowly. Spend most of the first few days just walking. Then, start walking and running on the same day. Run or jog a short distance, then walk for a while, then, run, then walk. Follow that pattern for 15--30 minutes a day. Slowly make each run longer and each walk shorter. Later on, you can increase your distance, speed and exercise time.

找出最后一段的主题句。

If you’re away from home, feeling a bit blue or searching for some comfort, the Danes have a solution. It’s called “hygge”. Coming from Danish culture, but popular with the British in 2018, hygge is much more than just a word, it’s becoming a feeling around the world.

The hygge means the sense of happiness you get when your family is gathered together at new year or Christmas. It is all about the pleasant feelings of home: the smell of your mother’s cooking, your partner’s arm around your shoulder and so on.

Hygge is an antidote(良药) to stress. You know when you’ve got it, a gentle warmth starts spreading through your body. Another important part of hygge is that it has nothing to do with modern technology. It’s a period time to relax your tired mind and eyes. So, put down that smartphone and turn off the computer.

You should also know that hygge is not about healthy eating or more exercise. In fact, it’s just the opposite. You’re supposed to be lost in what you like: enjoy sweet snacks and calorie-laden cakes freely. Let yourself think of what happened in the past, and remember the childhood songs of your distant youth with a smile. If it helps, wrap yourself in a warm blanket and sleep with one of your favorite books (not a pill or e-reader).

If Denmark seems too far, then think of old Beijing with its hutong and courtyard houses. Picture yourself sit around a traditional stove with your loved ones, eating dumplings and chatting about the old days. Let yourself drift back in time to a period where everything is relaxing, and there is no need to reply to any e-mails or text messages. They did not exist(存在) back then.

Now you’ve really understood hygge without going to Copenhagen.

What do we really mean by being open? Being open is a kind of invitation to others to come in, to speak and to share. It is important for others to get to know how we think and feel. In this way, we will be understood and accepted by others. If we aren’t open with others, we won’t fully believe in ourselves or others.

  Here are a few ways for you to be more open. First, make your outside behavior the same as your inside feelings and thoughts. Second, share how you really feel about something instead of just opinions. Third, try to change your questions into statements (陈述句) and talk in the first person so that people will understand you more easily. For example, you might say, “I feel happy that you’re here.” instead of “Are you glad that you’re here?” Finally, try not to say, “I don’t know.” This usually means I don’t want to think about it any more.

  Remember also that it is not suitable to be open with everyone in every situation. You may want to be more open with close friends, but not with people you don’t know well, because you are not sure how someone else will use what they know about you. Besides, some people may not be used to too much openness. If we say everything we feel or think to them, they will feel very uncomfortable at times.

  In all, being open is a good way for us to get on well with other people, but we’d better keep the balance (平衡) between being open and not being too open.

Many students like to talk about fashion,because they want to be popular at school.But I don't think they are popular at school.Here are their opinions and my opinions.

There are many different ideas about when and where the first toothbrush was invented. Some say it was invented in China around the 11th century. Others say the Romans(罗马人) invented it around the time of Caesar. Nobody knows the exact history of teeth cleaning.

Before the first toothbrushes, sharp(尖的) objects were used to clean teeth.

It’s believed that tribes(部落) in Africa and Australia invented the idea of cleaning their teeth. The modem toothbrush with bristles(毛) was invented in China much later in the 16th or 17th century. Toothbrushes moved to Europe in the mid 1600’s and then became widely used in the area. Animal hair was the first type of bristle to be used.

Today, toothbrushes have nylon(尼龙) bristles and normally have a plastic handle. Animal hair was replaced by nylon in 1938. Electric toothbrushes were invented and marketed in 1880 by “Dr Scott”. The popularity of the electric toothbrush did not take off until after World War Ⅱ. When the cordless(无线的) model was invented in 1960, its popularity increased a lot.
