Exercising is a good way to keep fit. However, many people do not know how to exercise well. Here are some tips.

    First, you should warm up. It is important to warm up before you exercise. You need to stretch your legs, arms, back and neck before you do any difficult activities like running.

    Second, you should find good places to exercise. You do not need to spend a lot of money. You can run or do sports in a park or in your school gym. You don't need to buy exercise equipment for your home. Just get your body moving. 

    Third, don't work too hard. Choose a sport that you enjoy and then your exercise will be fun instead of work. Also, you only need to exercise a few times each week. If you exercise 30 minutes each time, you will stay healthy.

    Fourth, drink enough water. It is important to drink water when you exercise. Your body needs the water for energy and for keeping cool.

    Finally, you must be careful! If you hurt yourself while you are exercising, rest until you feel better. Exercising when you are hurt is bad for your health.

    When some plates(板块)of the Earth move suddenly, an earthquake happens. Many earthquakes begin under the sea. Earthquakes may happen anywhere on the Earth. They often happen near the mountains.

    During an earthquake, the shakings make rocks rise suddenly and even crack(断裂) open. Houses fall down. People are killed or hurt, and sometimes the whole villages or cities are destroyed.

    Can we do something to keep ourselves safe from earthquakes? Scientists have studied earthquakes and made maps that show the “earthquake belt（带）”. In area of these belts, it's possible for earthquakes to happen. In these areas we should build strong houses to fight against earthquakes.

    In the future, Scientists will be able to tell when and where an earthquake will attack before it happens. They can also tell people what to do and how to deal with it.

Do you know the lion dance? It's part of traditional Chinese culture. People often perform in the night 1 the Chinese New Year. They also perform it for other happy occasions（时刻）. The lion dance is believed to 2 good luck and success. 

There are many different stories about how the lion dance 3 . One of them is like this! Hundreds of years ago, a monster called Nian came to a village in China. The villagers were 4 . Luckily, a lion chased（追逐）Nian away. A year later, Nian came back again, 5 this time the lion couldn't help. The villagers had to 6 themselves. Their "lion" danced, jumped and chased Nian away. For this 7 , people began to perform the lion dance before the Spring Festival to chase bad luck away. 

There are two different kinds of lion dances. In the southern lion dance, the dancers try. 8 to perform like a real lion. Their "lion" may shake its body. The dance can be funny. The other kind is the 9 lion dance. It has more martial（军事的）art skills like rolling and jumping. Both the southern and northern kinds are very interesting to watch, but it takes a lot of 10 to perform well. Both kinds are considered to be traditional performing arts of China. 

 Wordle is a free online word puzzle game. You needn't pay or download(下载) it on the computer.You can just visit the website(网址) and start playing right away. The game was created by an IT worker Josh Wardle as a gift for his partner who loves playing games.

The easy rule of Wordle attracts many people. Wordle challenges people to find a five- letter word in six guesses. After each guess, the letters turn into different colours. Green means it's the right letter and it's in the right place. Yellow means the letter is in the word but in the wrong place. Grey means the letter's not in the word at all. Everyone plays only one word a day, so players are excited to solve it. If they manage to guess in the first or second try, they can't wait to show their results on Twitter. Wordle has suddenly become a huge part of people's lives. That's why Wordle has been sold to the New York Times for more than a million dollars.

 Here are some tips for you to win in fewer guesses. For your first guess, it's a good way to pick a word that has at least two vowels(元音) with popular consonants(辅音)r,t and s. If you have a yellow k in the second place of your first guess, you might try placing it in the fifth place- many five- letter words end with ck. It is also helpful to think of letters often appearing in sets of two or three, like tr/ ai/ ing. Don't reuse grey letters and don't forget letters can appear twice.

 Wordle attracts lots of players since it is such a simple game. But will players keep being crazy about it in the future? Let's wait and see.

Everyone knows water is important to all living things. But do you know these interesting1 about water? 

Without water, the Earth would look 2 the Moon. People can live for a long time without food, but only 3 days without water. Scientists say about 70% of the human body is made up of water. Water4 up about 83% of our blood, 75%of our brain, and 80% of our lungs (肺). About 95% of a tomato is water, and about 80% of an apple is water. So 5 can we do to help with water problems? 

Keep a shower to 10 minutes or 6 time. It helps save much water. Use a broom to sweep the floor, the stair, the garage( 车 库 ) , or the sidewalk instead of water.

7 throw your used water away. Instead, you can use some to water plants or run the toilets. Use a bucket( 桶 )of water to 8 your bike or the family car instead of water pipes. 

Use water only 9 you need it. Don't leave water running. Be sure to tum the tap10 when you are not using it.
