A group of swans flew down to a beach where a crow(乌鸦)was jumping around. The crow watched them with disdain(鄙视).

    "You have no flying skills at all!” he said to the swans. “All you can do is to move your wings. Can you turn over in the air? No, that's what you can't do. Let's have a flying competition. I'll show you what real flying is ! "

    One of the swans, a strong young male, took up the challenge(挑战). The crow flew up and began to show off his skills. He flew in circles, did other flying tricks, and then came down and looked proudly at the swan.

    Now it was the swan's turn. He flew up, and began flying over the sea. The crow flew after him, making all kinds of comments(评价)about his flying. They flew on and on until they couldn't see the land and there was nothing but water on all sides. The crow was making fewer and fewer comments. He was now so tired that he found it hard to stay in the air, and had to try to stop himself from falling into the water.

    The swan pretended(假装) not to notice and said, "Why do you keep touching the water, brother? Is that another trick?"

    "No," said the crow. He knew he had lost the competition. "I'm in trouble because of my pride! If you don't help me, I'll lose my life... "

    The swan took pity on him, and took him on his back and flew back to the beach.

There were once two doors in the same house. One was a beautiful living-room door, and the other was just a/an 1 bathroom door.

They both had terrible lives. The house was full of 2 children who were always slamming (摔门) and kicking the doors. Each night, when everyone was asleep, the doors would talk about their poor 3 . The living-room door was always ready to shout with anger, but the bathroom door would calm him down, saying, "Don't worry. They're children. They'll soon learn. Wait and things will 4 ."

And so the living-room door would calm down for a while. But one day, after a big party and much slamming and kicking of the doors, the living-room door 5 lost his temper and became very angry, saying, "That's enough! The next time someone slams me, I'm going to 6 , and they'll learn how important I am." The next day, the first time he was slammed, the living-room door broke.

This caused great 7 in the house, and the children were punished. But after a few days, the house owners didn't want to have a broken door. Instead of 8 it, they decided to buy a new one. The old door was abandoned (抛弃).

By then the beautiful living-room door regretted what he had done. For not being 9 enough, he was now abandoned, waiting to be turned into firewood. Meanwhile, his friend, the not so good-looking bathroom door, remained in his place, and the children were treating him with greater 10 than before.

Zhang Ming, a college student, created a 9-page "WeChat guide". With pictures and simple words, the step-by-step guide teaches people to send messages（信息）, take pictures and make video calls. Zhang made the guide for his parents. "My parents are getting old. They need an easy way to used new technologies," he said. 

Zhang's experience is common today. Around the world 40% of parents learn about new technologies from their kids. Parents used to teach kids about almost everything. Now for the first time, the teachers become the students, and the students turn into the teachers. The change of roles comes from the rapid development of the technology. The Internet gives kids ways to get more information besides from asking the older generations: So, in the age of the Internet, it's possible for kids to know more than their parents. 

According to（根据）a study, 56.7% of Internet users in China are under 30. The younger generation usually acts as a link between their family and the new environment. They teach their parents new technologies. Then their parents can better understand the new world. 

"Teaching my parents about WeChat makes me closer to them. People can communicate more by surfing the Internet. Why do we keep our parents out?" said Zhang.

Today, my classmates and I had a study tour to the City Science Museum. It took us {#blank#}1{#/blank#} hour to get there by bus. 

In the museum, we {#blank#}2{#/blank#} (see) many kinds of inventions such as robots, rocket models, some dinosaurs and so {#blank#}3{#/blank#}. What's more, we took part in many {#blank#}4{#/blank#} (meaning) activities. For example, I used a 3D {#blank#}5{#/blank#} (print) to make a small bridge. Tony, the {#blank#}6{#/blank#} (good) friend of mine, took quite a few {#blank#}7{#/blank#} (photo) at the museum. {#blank#}8{#/blank#} we were a bit tired, we thought the study tour was educational for us. We had learnt a lot of knowledge on science and technology outside the classroom. 

However, the lunch we had during the trip didn't taste good at all. That's why I suggest that students should bring their own food by {#blank#}9{#/blank#} (them) on next visit. This way, they can eat more {#blank#}10{#/blank#} (enjoy) meals and also keep their energy up throughout the learning adventure.
