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.

On March 21st, a passenger plane with 132 people crashed（坠落）in Guangxi. The China Eastern Airlines flight MU5735 left Kunming at 1:11p. m. and would arrive in Guangzhou at 3:05 p. m. Unluckily, the plane was out of the control and {#blank#}1{#/blank#}（heavy）crashed into the ground. The plane accident happened in the mountain s near Molang Village in Tengxian in the city of Wuzhou at 2:38 p. m., and {#blank#}2{#/blank#}（cause）a forest fire.

President Xi Jinping said he was {#blank#}3{#/blank#}（shock）to learn about the accident. And he made a quick {#blank#}4{#/blank#} （decide）to ask the local government（当地政府）workers to take action to do {#blank#}5{#/blank#}（what）they can to save the people on the plane. Since the crash place is in a mountain forest, finding the black box depends {#blank#}6{#/blank#} both drones（无人机）and the people in the armies. On March 23rd, they found passengers' personal things at the crash site, including wallets, ID cards {#blank#}7{#/blank#} bank cards. But all the passengers {#blank#}8{#/blank#}（be）found dead.

China Eastern Airlines made its sign on Sina Weibo black and white and changed its website, {#blank#}10{#/blank#}（show）its sadness after the accident.

Cameras（照相机）ready，and. . . action！

Nowadays, smartphones are popular all over the world. People use the smartphone to do many things, such as calling, surfing the Internet and playing games. Almost all smartphones have a camera. And with some free apps like Douyin, you can {#blank#}1{#/blank#} (easy) share your videos live. Besides, you might be lucky enough to get tons of attention and have a great number of fans soon. How great it is!

However, {#blank#}2{#/blank#} popular online broadcaster（播音员）was caught by the police several years ago. Why？ During one of her broadcasts，she made fun of China's national anthem（国歌）. {#blank#}3{#/blank#}my opinion，the girl only wanted to amuse（取悦）her fans, but she {#blank#}4{#/blank#}（break）the law（法律）truly. 

Since the Internet appeared in our lives, it has brought a lot of fun to us, and many people have{#blank#}5{#/blank#}（difficult） stopping using it. However，improper information which spreads（传播）on the Internet is bad for mental health. What is {#blank#}6{#/blank#} (bad), if you spread such information online, you may break the law. That is to say, you may be noticed and caught by the police if you spread such information online. And anyway，when you are looking for a job，some companies（公司）will look at your online posts（帖子）before they make a {#blank#}7{#/blank#}（decide） about whether to give you a chance of interview. 

Nobody is allowed to break the law, {#blank#}8{#/blank#} no matter where you are, you should never do that. Ask {#blank#}9{#/blank#} (you) what results your actions may have. When you are using the Internet, think{#blank#}10{#/blank#}（two）before you click（点击）the "share" or" broadcast" button. Maybe no one is watching you，but you must be responsible for what you do!
