Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves. Some birds love eating locusts (蝗虫), but birds cannot easily catch them, why? It is because locusts change their colours with the change of the colours of crops. When crops are green, locusts look green. But as the harvest (收获) time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for living and appear only at night.

    If you study animals' life, you'll find the main use of colour is to protect themselves. Bears, lions and other animals move quietly through the forests and they cannot be easily seen by hunters. This is because they have the colours much like the trees.

    Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体) when it faces danger. While the liquid spreads, its enemies cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

    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.

    What is the hardest sport in the world? Some people say it's boxing (拳击), because boxing is dangerous and boxers have to be strong and fast. Other people say the hardest sport is soccer.

    However, most people say the hardest sport is the triathlon (三项全能运动). A triathlon is a race that includes three sports. First, racers swim. After that they ride bicycles and finally they run. In the most common triathlon, racers swim 1.5kilometres, bike 40 kilometres, and run 10 kilometres. The winner is the person who finishes the race first.

    There is another kind of triathlon too. It is called the "Ironman Triathlon (铁人三项)". This triathlon is much longer. People who finish this triathlon are called "ironmen" or "ironwomen". This is because these people are so strong that their bodies are just like iron (铁).

    In the past, there were other races including three sports. However, they didn't use the word "triathlon". That word was first used to describe a race in California in 1974.

    Triathlon racers have to train very hard for their races. Many of them swim and run. A lot of people also do things like yoga (瑜伽). They have many different ways to prepare, but they all have the same goal. They want to be in perfect shape.

    To be an ironman or an ironwoman, you have to be strong and smart. You should know how to save energy during the race.

    Some insects, such as butterflies and ladybugs, are quite beautiful, {#blank#}1{#/blank#}did you know that many insects are also edible(可食用的)?

    Aletheia Price knows this—and a lot more about –about bugs(虫子). She also thinks that you should try {#blank#}2{#/blank#}some. If you visit the website www. eatbug.com, you will find all kinds of{#blank#}3{#/blank#} about edible insects. Most of it was {#blank#}4{#/blank#}by Aletheia Price when he was fifteen years old. Aletheia started eating bugs at the age of thirteen. Soon, she found that she really {#blank#}5{#/blank#}eating some of them. She also became interested in finding out more about which kinds of bugs could be eaten and {#blank#}6{#/blank#}to cook them.

    According to Aletheia, there are at least 1,462 kinds of edible {#blank#}7{#/blank#}. Some of her favorite dishes include mealworm, chocolate, chip, cookies and chocolate-covered crickets(蟋蟀).

    Aletheia knows eating bugs is not for {#blank#}8{#/blank#} . But if you think about it, you may feel that eating bugs is a good {#blank#}9{#/blank#}. There are millions and millions of edible bugs in this world. If you could get to used to eating {#blank#}10{#/blank#}, we would have plenty of food for everyone.

Computers make people's lives really easy. People can use their computers for working, {#blank#}1{#/blank#} (shop), or playing games. Laptop (笔记本) computers make people's lives even {#blank#}2{#/blank#} (easy) as people can take laptops anywhere. They can work, shop, or play games any place {#blank#}3{#/blank#} any time. {#blank#}4{#/blank#} there is a problem with laptops. People can {#blank#}5{#/blank#} (burn) by them!

People who sit with laptops on {#blank#}6{#/blank#} (they) legs for hours and hours have noticed they get dark marks on their legs. The hot laptop is toasting the skin. {#blank#}7{#/blank#} (doctor) have noticed more people show up with "toasted skin syndrome (综合症)". The marks are not {#blank#}8{#/blank#} (danger), but they look strange because they are just in one spot on people's legs.

Companies that make computers tell people not {#blank#}9{#/blank#} (let) warm computers touch bare skin for a long time. Wearing pants and putting a laptop's case under the laptop is {#blank#}10{#/blank#} (usual) enough to protect one's skin from the computer's heat.
