Did you hear the song called Heartbeat? It's very {#blank#}1{#/blank#} in the world. Zade Dirani released (发布) this song {#blank#}2{#/blank#} March 15^th 2018 to remember the seven years of war (战争) in Syria. In the song, one of the {#blank#}3{#/blank#} is Ansam. She is a ten-year-old girl. When she was born (出生), she couldn't see {#blank#}4{#/blank#}. But later people found she could sing very well. She sang the song Heartbeat with another 40 children. They all lost their parents in the war. In this song, children hope (希望) they can have a happy {#blank#}5{#/blank#} and there is no war in Syria. But many people lost their homes {#blank#}6{#/blank#} the war broke out (爆发) on April 13^th 2018 again. Everybody hopes the war can {#blank#}7{#/blank#}. We hope all the kids have food to eat. They can live with their parents. They can study in the classroom. They can sing under the trees and swim in the sea.

    We are lucky to live in a great {#blank#}8{#/blank#}, China. Now we have food to eat. We are {#blank#}9{#/blank#} in the classroom. We {#blank#}10{#/blank#} reading books in the library. So we should study hard and love our parents and friends.

{#blank#}1{#/blank#}(几个月前), I read a book. It made me feel it's a {#blank#}2{#/blank#}to always buy more things than I need. I started cleaning my house and got lots of unnecessary things. It's a w{#blank#}3{#/blank#}and trouble for me. And then I{#blank#}4{#/blank#}(考虑)what to do with them.

This question made me think of Garage Sale for Orphans. It helps people clean out their houses and t{#blank#}5{#/blank#} things into money that can help homeless kids{#blank#}6{#/blank#}(全世界). It r{#blank#}7{#/blank#}me. So I ask my boys for help, and they loved the idea of helping others.

They walked from door{#blank#}8{#/blank#}door to ask the{#blank#}9{#/blank#}/'neɪbəz/ for the things they don't need. At first, I wondered if we{#blank#}10{#/blank#}able to fill a box or two. Finally, however, we had ten boxes full of different things. Then it was time{#blank#}11{#/blank#}the yard sale.{#blank#}12{#/blank#} (即使；尽管)we had ads in the newspaper and online, I was still not sure whether whether anyone would come. {#blank#}13{#/blank#}(令我们惊奇的是), so many people came to our yard sale. I p{#blank#}14{#/blank#}to get 400 to 500 that day. At last, we got $743.23! We sent the money to the poor children in Haiti. Thanks for all the people who{#blank#}15{#/blank#}helped us.

These days, more and more people like the "city walk" around China. The city walk is a kind of city tour coming from the UK. It means tourists follow a planned route（路线）working deeply on the city's history and culture. During the traditional kind of travel, people need to follow a group of people. But city walk routes are special for every tourist. People probably choose a route on their own and move on foot without a purpose. They can also talk with locals（当地人）and taste local food on their way. 

City walkers may be tourists from other places or local young people. For tourists, by taking part in a city walk, they can learn the city's history and culture. For the local young people, they may spend weekends knowing more about their living places. And they even share their routes and places online. So more people get interested in their cities and come to visit them. 

Now the city walk is very hot. However, we also find that to make money, some travel agencies（旅行社）may make some routes without understanding the culture and history of a city. That will make tourists lose interest in the city walk. What's more, many young people spend much time taking photos to just show themselves online. 

The traditional Chinese lunar calendar divides the year into 24 solar terms. Grain Rain（谷雨）, at the last term in spring, generally starts on April 20th and ends on May 4th.

Grain Rain comes from an old saying, "Rain brings up the growth of hundreds of grain", which shows that this period of rainfall is very important for the growth of crops. Here's something that you may not know about the Grain Rain.

Seasonal characteristics

When the Grain Rain ends, the summer starts And the temperature rises much higher than it does in March, With dry soil and heavy winds, sandstorms may happen more often.

Customs in southern China

There is an old custom in southern China that people drink tea on the day of Grain Rain. Spring tea during Grain Rain is good for the eyes.

Traditions in northern China

People in northern China have the tradition to cat the vegetable toona sinensis（香椿） during Grain Rain. An old Chinese saying goes "toona sinensis before the rain is just like silk". The vegetable is good for the stomach and skin.

Grain Rain Festival

The Grain Rain Festival is celebrated by fishing villagers in northern China. Grain Rain marks the start of the fisherman's first voyage（航行） of the year. The custom dates back to（追溯到） more than 2000 years ago.

Biomimicry borrows nature's design ideas and applies them to solve human difficulties. Nowadays a lot of companies started to invent in ways that are as elegant as what nature manages to do, and their designers and engineers began to sit with biologists to learn how nature would solve whatever it is they're trying to solve. 

 Some biologists worked with Nike company on apparel(服装）that would keep an athlete cool at the 2004 Summer Olympics. In a hot, dry place like Athens, what kind of organisms have to keep themselves cool and how do they do it? They found an African reed frog——a champion adapter in the heater—to study. 

If a company is making a solar cell , Biomimicry scientists will talk about how a leaf captures energy with their designers. Or if they're looking for some way to create an impact-resistant car, 

Biomimicry scientists will explain how woodpeckers can peck trees all day without harming themselves. 

Companies get the catalog of inspiration from the natural world and create things that sip energy, a city planner, an architect-should take one biology class in school. 

If you take a look at the octopus, you'll notice it moves fluidly and precisely but of course without motors or noisy fans or harmful fuel. The giraffe's vascular system allows it to pump blood up to its head and dip its head without getting dizzy. The humpback whale's flipper has scalloped edges to calm turbulence, and that's being mimicked in a new kind of wind turbine that can rotate in very low wind speeds because of its shape. There's even a new kind of pacemaker based on the heart of the whale. 

One famous biologist once said, 'In nature, failures are fossils. The organisms that are still with us are proven Companies that created a new product inspired by an organism have decided to donate a percentage of their proceeds to conserve the habitats of the organism. 

In ten years, you'll be able to visit ocean parks that have been preserved with the proceeds from a no-heat ceramic recipe based on the abalone's mother-of-pear!

Choose the best answer:

Do you get angry when your friends sing loudly while you are trying to work? Or when your best friend does not wait for you after school? 

If you do, you need to take control of（控制）your feelings and stop getting angry so easily. Getting angry with people can cause you to lose friends. 

Gary Egeberg, an American high school teacher, has written My Feelings Are Just Like Wild Animals to help you control your feelings. It tells teens how to stay cool when bad things happen to them. The book says that getting angry only makes problems worse. 

It can never make them better. Getting angry is not a natural（自然的）way to act, the book says. It is just a bad habit, like smoking. The book says you can control your anger easily—all you have to do is to tell yourself not to be angry. 

When a baby falls over, it only cries if people are watching it. Like a baby you should only get angry if you are sure it is the right thing to do. 

The book gives many tips to help you if you get angry easily. Here are our top three: 

①Keep a record. Every time you get angry, write down why you are angry. Look at it later and you will see you get angry too easily. 

②Ask your friends to stop talking to you when you get angry. This will teach you not to be angry. 

③Do something different. When you get angry, wall away from the problem and go somewhere else. Try to laugh!
