A new rubbish sorting system (垃圾分类系统) has been put into use in Fangchengyuan Community in Beijing. Local people not only sort their rubbish, but also put QR codes (二维码) on it.

    "When the rubbish is collected and the codes are seen, I will get reward points to exchange for small gifts and even some money," one of the local people told reporters. "It's really creative and encouraging."

    This smart system has been carried out in 350 communities in Beijing. The capital of China has joined a list of cities in the country that take action to support rubbish sorting. For example, Shenzhen and Shanghai have made laws to punish people and organizations for not sorting rubbish correctly.

    China produces quite a lot of rubbish every year. Much of the rubbish is buried (填埋) in soil or burned without being sorted. Landfills (填埋场) take up a lot of land and have a risk of polluting the soil and water nearby. And burning rubbish can produce harmful gases. Through rubbish sorting, we can reduce the use of landfills and air pollution.

    What's more, rubbish sorting saves resources, which could bring economic benefits (经济利益). For example, a ton of waste paper can be reused to make about 850 kg of paper, saving 17 trees and 50 percent of water. Because of the benefits, some countries have developed successful sorting systems.

    Japan has a strict and detailed system. When people throw away a water bottle, the cap, the wrapper (包装纸) and the bottle itself have to go into three different bins. Every year, families receive special rubbish sorting timetables and directions from their local governments. They are advised to follow the timetables and directions when they throw away rubbish.

    In Australia, every family is provided with three rubbish bins—the red lid (盖子) bin for "general waste" like food and plastic bags, the yellow lid bin for "recycling" like steel and glass, and the green lid bin for "green waste" such as grass and leaves. On the streets, the bins are printed with pictures of the things that are allowed inside. It makes recycling quite easy.

How did you spend your summer holiday last month? I'd like to tell you 1 happened to me during my holiday. 

My 2 planned a relaxing and happy trip. We didn't need to keep up with our work and studies. On the first day, 3 we started out for Shanghai, we saw on TV that the traffic was heavy. So my parents 4 not to drive our car but to take the bullet train(高速火车) to Shanghai. It was the first time that I had ridden on the bullet train, so I was really 5 .

On the way, an American girl sat next to me and I talked to her. She told me that she came here for a short stay—her father came to China on business. In one year he would 6 to his company in the US. "How are you getting along here?" I asked. "Pretty good. I 7 the life here. China is a beautiful and great country. Besides, Chinese people are pretty 8 , "she said. Hearing that, I felt proud that I'm Chinese! With new friends around, the girl still missed her friends in the US very much. "It doesn't matter. I could always connect with them by writing letters and emails or making phone calls, " she said with a sweet9 . It was so great for her to be able to go through life in10 countries and cultures. I hope I can experience different cultures in other countries some day. 

Umbrellas could be one of the world's most important inventions. The first umbrella was invented over four thousand years ago. 

Umbrellas were used on sunny days at first. Chinese people were the first to use their umbrellas on rainy days. They waxed (给……打蜡) their paper umbrellas so that they could be used when it was raining. 

The word "umbrella" comes from the Latin word, umbra. It means shade (背阴). Starting in the 16th century, the umbrella became popular in the Western world, especially in northern Europe, where it often rains. At first, people thought that the umbrella was only suitable for women. 

Then a famous English traveler, Jonas Hanway (1712-1786), carried and used an umbrella in England for thirty years. Because of him, men began to use umbrellas. 

In Europe, early umbrellas were made of wood and covered with canvas (帆布). 

People used very hard wood to make umbrella handles. In 1852, Samuel Fox invented a new kind of umbrella with ribs (伞骨) made of steel. 

Samuel also started a company called English Steels Company. After that, compact collapsible (可叠) umbrellas were the next important step in umbrella production. 

①We all want to have great parties on our birthdays. But it's not easy to have a great party. Let me tell you how to have a great party. 

②We need to have it on the right day. If your friends or classmates are busy on that day, some of them will not come to your party. Saturday and Sunday are good days for a party because the students don't go to school. You can have your party on Saturday afternoon. It's OK to have it on Sunday afternoon, too. 

③You need to invite (邀请) your friends and classmates to your party. Tell them when and where you have the party. If you have the party on Saturday, you need to tell them on Thursday. Then they can have time to prepare (准备) a present for you. 

④Think about games for the party. If your friends and classmates like playing games at the party, you need to think about proper (合适的) games. The games need to be easy and interesting for your friends and classmates. Then you can have a good time at the party. 

I often hear some students say English is difficult and gives them a headache. So they can't learn it well. But English is very easy for me. {#blank#}1{#/blank#} I'm very glad to tell you something about how I study English. 

{#blank#}2{#/blank#} When I was in Grade Three, we had a new subject— English. It was new to me. I was interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was!{#blank#}3{#/blank#} Our English teacher often teaches us English songs, and the songs sound nice. I often think how interesting English is!

Second, as English is a foreign language, I learn it well in the following ways:{#blank#}4{#/blank#}Then practise again and again, and never be tired.{#blank#}5{#/blank#} Whenever I have a question, I must make it clear by asking our English teacher. How happy I am when I understand it!
