Here is a story: A man sees a butterfly (蝴蝶) . The butterfly tries to get out of its chrysalis (蛹) . F{#blank#}1{#/blank#}sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out e{#blank#}2{#/blank#}. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesn't struggle (挣扎；奋斗) to leave the chrysalis, it can't fly！The struggle develops the e{#blank#}3{#/blank#} in the butterfly which makes it fly. Similarly, the challenges of life bring out the best in young people and make the fly.

When people are young, meeting and overcoming challenges will make them s{#blank#}4{#/blank#} and ready to face life.

When we look at successful people, we see that the most successful of them are people who have had to struggle.

One famous businessman, who now o{#blank#}5{#/blank#}many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. He had to b{#blank#}6{#/blank#}up a big family. He took up the challenges and overcame them. Today his brothers and sisters are leading s{#blank#}7{#/blank#} lives.

Sometimes challenges do not appear to us because we keep away from them. So, some parents and teachers actively encourage young people to face challenges. They might organize some a{#blank#}8{#/blank#}for young people which provide them with challenges, like rock—climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of t{#blank#}9{#/blank#}. For countries to continue to become successful, it is i{#blank#}10{#/blank#}that the young people learn to meet challenges and overcome them.

If you want to go shopping, think about how much money you can spend for new clothes.Think about the kind of clothes you really need.Then look for those clothes on sale.

There are labels (标签) inside all new clothes.The labels tell you how to take care of your clothes.The label for a shirt may tell you to wash it in warm water. A sweater label may tell you to wash it in cold water.The label on a coat may say "dry clean only". Washing with water may ruin (损坏) this coat. If you do as the directions on the label, you can keep your clothes looking their best.Many clothes today must be dry cleaned.Dry cleaning is expensive. When buying new clothes, check to see if they need to be dry cleaned.You will save money if you buy clothes that can be washed with water.

You can save money if you buy clothes that are well made.Well-made clothes last longer.They look good even after they have been washed many times. However, clothes that cost more money are not always better made.They do not always fit better.Sometimes less expensive clothes look and fit better than more expensive clothes.

How can you remember a song for a long time? Why does your teacher use songs to teach you English? There is a scientific reason for this. 

Researchers (研究者) are studying the relationship between music and remembering a foreign language. "Singing could be a new way of learning, especially for a foreign language. The brain likes to remember things in a catchy (悦耳易记的) and relaxing way. For example, children can remember difficult words quickly when they are in a song," said Dr. Karen Ludke. If children find it difficult to learn foreign languages, this new way may help. On his blog (博客), Dr. Ludke wrote "A listen—and—repeat singing way can help to learn foreign languages and open the door for future research in this area."

Many language teachers know the importance of music and they often use it in teaching and learning. Hua Zhuying, a teacher at a Chinese language school in Washington DC, likes using songs in teaching Chinese. She said, "I use music all the time to teach children Chinese. For little kids usually we use English songs but teach them the Chinese lyrics. Not only does it work, but it is fun for children. Sometimes I think if I learned English that way when I was young, maybe I could speak English much better."

Our brain likes music in learning languages, especially for remembering. If you are still having problems in learning a language, why not try singing it out?

Do you often run outdoors to keep healthy? Have you ever thought about how running helps to clean up the earth? Sometimes creative mind can bring us win-win (双赢) situation.

 Plogging, a new way to exercise, began in Sweden. The name "plogging" comes from two words—the Swedish word "plocka", which means "to pick up", and the word "jogging", which means "to run slowly". A Swedish man called Eric started the movement. He saw rubbish here and there when riding to work each day. He became worried about the dirty environment and decided not to go to work by bike any more. Instead, he began to run to work and pick up the rubbish at the same time. To his joy, more and more people followed him and soon plogging became popular.

Many people choose plogging instead of just jogging because they think plogging is a good way to help clean up the earth. Sometimes rubbish is difficult to collect because it may scatter all around. But if the runners pick up the rubbish on the way, it is quite different. After all, many hands make light work. Another reason is that plogging burns 48 calories (卡路里). According to a reseach, plogging for 10 minutes burns 48 calories, while usual jogging for 10 minutes burns about 39 calories.

Everyone on the earth should play a part in cleaning it up! It's time for us to take action together. So ready? Let's plog tomorrow!

①Do you have a tidy desk or an untidy desk at home? Do you want to keep your desk clean and tidy for a long time? A tidy desk helps you find things easily and do things well. It is also helpful for your study. Here are some tips（提示）for you.

②First, only put things you need on your desk. For old books, you can put them in the bookcase. Get a box for small things you don't need every day, and you can put your pens and pencils in a pencil box.

③Second, don't put food or drinks on your desk, because they can make your desk dirty. Go to the kitchen when you want to eat.

④Third, put important things next to you. Then it is easy for you to get them. If you have a drawer（抽屉）under your desk, you can put things there.

⑤Fourth, clean your desk every day. If you do it every day, you can have a new day with a tidy room the next morning.

⑥If you do these things, you can have a tidy and clean desk. Why not have a try now?
