Do you think doing housework is a hard task for you? Have you ever thought of inventing something to make1easier? A boy named Sam Houghton did and he2a two-head broom (扫帚).

Sam was just three years old when he came up3his idea. He saw his father sweep up garden leaves and change brooms while trying 4large leaves and litter.

Now he is5poster boy for a new show at the British Library in London called "Inventing the 21st Century". To celebrate inventions and encourage new inventors, the famous library is telling the story of 6inventions coming out of Britain in the past 10 years. Sam's broom7by big companies, and the brooms are very popular in England.

Young Sam Houghton is now eight years old and has another invention. He has made a balloon popping machine (气球爆破装置) for play centers. He said, "We don't want children to cry because of 8bangs (爆炸声) of balloons. I used a box to take away the bangs 9they can't scare (惊吓) the children."

Have you ever wanted to be a great inventor? Watch10, think it over and work hard. Maybe you will be an inventor. Do you think so?

My parents always told me that I couldn't dance, because it was a girl's sport. But I never1 my dream of becoming a dancing star. I practiced 2, learning from books, movies, and shows. However, without my parents' 3, that dream seemed impossible to achieve. One summer, my little sister Mary was going to dance lessons. I immediately offered to take her to the lessons. What a good4 to learn dancing!

One day Mary asked me to dance with her in the school dancing competition, because5 of the boys in her class would like to do that. They thought she was slow. "You can be a good dancer!" I6 her." Let's show those people that they are wrong!" In the following months, we practiced every evening, still hiding from our parents.

 Finally came the big day. I became 7 when I saw my parents watching the competition. But as the music began, I took a deep breath and tried to put my heart into the dance. We moved perfectly, shining with pride. From the 8of the crowd, I was sure we had done a good job.

When we got off the stage, my father came towards me. He put his hand on my shoulder. "Well done, Son. I have to say you are 9 to dance. Go for it and make us proud."

Everyone has to go through lots of difficulties 10he achieves his dream. I know that the road ahead won't be easy, but I will not be afraid any more.

A caterpillar(毛毛虫) that eats plastic bags could hold the key to solving plastic pollution, scientists say. Researchers at Cambridge University have discovered that the caterpillar which eats beeswax(蜂蜡), can also degrade(降解) plastic.

Experiments show the insect can break down the chemical bonds(键) of plastic in a similar way to absorb beeswax. Each year, about 80 million tons of the plastic are produced around the world. The plastic is used to make shopping bags, food packaging, one-off raincoat and other things, but it can take hundreds of years to degrade completely.

However, caterpillars can make holes in a plastic bag in under an hour. "The caterpillar will be the starting point. We need to understand the details under which this process operates. We hope to provide the technical solution to cutting down the problem of plastic waste," the scientist said. And the scientists who discovered it want to speed up the process of discovering the chemical secrets behind the natural degradation of plastic. They think something in the caterpillar—as well as the insect itself—might play a role in breaking down plastic.

If the chemical process can be found out, it could lead to a solution to managing plastic waste in the environment. "We are planning to use this finding in a practical way to get rid of plastic waste, working towards a solution to saving our oceans and rivers," said the scientist. "However, we should not feel good to dump plastic on purpose in our environment just because we now know how to degrade it."

Many years ago, a girl with a red birthmark (胎记) came to my classroom. She was so ugly that the whole class all kinds of tricks on her. I had even taken the lead in laughing at her.

But she didn't mind at all.  she was always smiling at all of us. She did a good  at all her subjects. At a class meeting, she was chosen as  representative(代表) of excellent students to speak in front of the class.

"My mother told me that I was a child kissed God. He wanted to put a mark on my face so that he could remember me. He loved me and cared for me with all heart. I've been very lucky since I  born. You see I got the first place in the exam this time. I have no  to decide what I look, but I can decide what I want to be. If I look at the world with tender(温柔的)eyes, I will feel lucky and happy. If I look at the world with unfriendly mind, I will feel  and sad," she said.

I was ashamed of what I had done. I laughing at her before. She made me understand: what kind of mental world a person has, what kind of life she will have. We can't change the world, the world is what your heart is like.

In the past ten years, the use of social media has grown in a way that no one could have guessed.

A main feature of social media is its volatility(易变). Trends(流行)come and go, disappearing almost as quickly as they appear. So, what were the main social media trends of 2018?

Short video apps, such as Tik Tok and Douyin, took the world by storm. The Telegraph reported that Tik Tok was the 8th on Apple's App Store in April. And Douyin had more than 300 million active users in June in China, CNBC said.

The sense of community that users of short video apps get is another main feature. Liza Koshy, a user of the US app Musically who has over 2 million followers, said that she was very excited when anyone said that her video had "encouraged" them. "It's really cool because I think as social creators that's what we all are," she added.

Live streaming(直播)is a feature of our social media life that now seems as natural as sunrise. It's a pretty good idea—you can watch anyone, anywhere, live.

China has taken live streaming to a whole new level. More than 100 million Chinese people monthly watch a live streaming video. Forbes thought that a number of reasons had led to the popularity of live streams. One of the most important reasons is that people don't have to know their real names.

Although we use social media all the time, that doesn't mean that we understand the influence it is having on us. We should pay attention to both the time we spend on it and its influence on our minds.
