    China's national anthem, March of the Volunteers, is a song that we learn at the beginning of primary school and sing at every flag-raising ceremony. And now, there's even a law to protect it.

    Last September, the government passed the National Anthem Law, which became effective(生效) from Oct.1, 2017. It states how we should sing or play the song, requiring all of us to behave towards it politely.

    Primary and middle schools must teach the anthem to their students and make them understand the song's spirit and history. Moreover, the law requires us to be serious when we are singing the song. We can't joke about it or change the song's words or music. If someone breaks the law, he or she can be detained for up to 15 days, or face further punishment in more serious situations. The national anthem is different from other songs – it is the symbol of our country.

    Many foreign countries also have laws for their national anthems. For example, American school children should put their right hand over their heart while singing their country's anthem at school. In Russia, the national anthem must be played on television and radio before the start and end of broadcasting. And in the Philippines, people are required to sing the national anthem with feelings when it's played in public.

    If someone asks me "Do you like music?" I'm sure I will answer him or her, "Of course, I do." Because I think music is an important part of our lives.

    Different people have different ideas about music. For me, I like rock music because it's so exciting. And my favourite rock band "the Foxy Ladies" is one of the most famous rock bands in the world. I also like pop music. My classmate Li Lan loves dance music, because she enjoys dancing. My best friend Jane likes jazz music. She thinks jazz is really cool.

    "I like dance music and rock music very much, "says my brother, "because they are amazing."

    But my mother thinks rock music is boring. "I like some relaxing music, "she says. That's why she likes country music, I think.

Green Energy for Today and Tomorrow

Did you know that most of the energy we use comes from the sun? For example, the sun helps plants to grow. Plants that grew millions of years ago turned into coal, oil, and natural gas（天然气）. We call these fossil fuels（化石燃料）.

However, fossil fuels cause pollution. This is bad for the Earth. Fossil fuels are also nonrenewable. Some day they will be gone. So, scientists want people to use green energy.

Why is green energy important? First, it is clean. It doesn't hurt the Earth. Next, it is renewable. It won't run out. Green energy gives us almost 25% of the electricity we use today.

What are the main sources（来源） of green energy?

Water Power

Water power uses moving water in rivers and dams（堤坝）. Moving water has energy. Water power makes 

16.6% of the electricity we use.

Wind Power

Is wind power new? No, it isn't. People used wind power many years ago. Wind power makes 4% of the electricity we use.

Solar Power

Solar power comes from sunlight. The sun shines on solar panels（太阳能电池板）, and electricity is made. Solar power is now as cheap as some fossil fuels. It makes 

1.5% of the electricity we use.

Biomass energy（生物质能）

Biomass energy is energy that we get from plants around us. For example, dead wood or grass is burned in power stations. This makes electricity. Biomass energy is green energy because we plant new trees or crops（庄稼） after we use it. Biomass energy makes 2% of the electricity we use.

New Green Energy

The ocean rises and falls each day. This moving water can make electricity. We call it tide power. There is also heat under the Earth's surface. Scientists can use this heat for energy, which is called heat power. We may find other sources of green energy in the future.

Some day, green energy could make 100% of the electricity we use. That's good news for the Earth!

How Can We Protect Ourselves

Self-protection is important for us. But how can we protect ourselves? Here are some advice.

The Chongyang Festival is also called the Double Ninth Festival. {#blank#}1{#/blank#} During the festival，Chongyang cake and chrysanthemum(菊花) wine are the traditional food. Climbing mountains and admiring beautiful chrysanthemums are interesting events. {#blank#}2{#/blank#} It has two layers(层) with nuts and jujubes(枣) between them. Since cake in Chinese is pronounced gao meaning "high" ，people consider climbing a high mountain to be the same as eating the cake. They also hope that they can make progress in the following days after eating the cake. {#blank#}3{#/blank#}

Drinking chrysanthemum wine is a necessary part of the festival. Chrysanthemums have the function(功能) of an antitoxin(抗毒素) and can drive the evil(邪恶) away. {#blank#}4{#/blank#}

It is said that by climbing a high mountain，diseases can be prevented. Many well­known poems were created to describe the scene and feeling of mountain climbing. Now，families，relatives or good friends gather to climb mountains to enjoy the beautiful scenery and share happiness of the holiday with each other. {#blank#}5{#/blank#}
