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.

During the old times, children didn't have smart phones, iPads or computers to play. They: thought of interesting games to play in their childhood.

●Stone（石头）balls

During the Qing Dynasty, kicking（踢）a stone ball around was a popular sport in the northern part of China, and it was often played in the winter to keep warm. Children made stones into small balls and kicked along with feet.

●Flying kites

Kites have quite a long history. The earliest kites were made of wood （木）, not paper. These days, the three most famous kites are the Beijing kite, Tianjin kite and Weifang kite, which each is very special. The swallow-shaped kite is the most popular Beijing style.

●Hide-and-seek

Hide-and-seek is a traditional game for children, popular around the country. There are two ways to play: Cover a child's eyes and ask him to catch the other kids while the other kids run around him. Or, more commonly, the children hide（躲）and one child must try to find them.

●Watching shadow plays（皮影戏）

The closest thing to watching a film or television for fun during the old times was going to see a shadow play. The artists manipulate puppets（操纵木偶）behind the screen, telling stories with music. During the Qing Dynasty, shadow play art was the most popular, and was played for every important time.

Several times each year the Queen gives afternoon tea parties at which guests are served tiny cakes filled with cream from her own cows. Cakes and sandwiches are bought in by footmen, yet you never see the Queen touch a thing. She

simply sits beside a big silver plate, pouring cups of tea for everyone and carefully avoiding the cakes.

At cocktail parties the Queen moves from group to group, chatting informally, and manages to make one glass of diet drink to last a whole evening. Tours abroad are difficult because hosts seem to believe the warmth of their welcome must be shown with wonderful state banquets(宴). But the Queen has perfected the art of appearing to enjoy her meal without actually eating much. During one visit to the Pacific islands of Tonga, a specially-prepared dinner was set up in   a hut made of wood and bamboo leaves. Deep holes were dug in the ground, filled with hot stones and baby pigs, and the pigs were slowly cooked with dry heat over several days. The Queen looked uneasily at her plate when she discovered a   whole roast(烤) pig was her serving.

Then she became uneasy when a turkey, some meat, bananas and an apple were also carried in for each guest. So she depended on her old favourite trick of talking with her host, King Tupou IV, carrying on a warm conversation. At the same time she pushed her food around her plate and only ate a piece of turkey and some fruit.

Reporters traveling with her have noticed that the Queen will sometimes seem so interested in a foreign leader's political(政治的) chat that she simply never has time to finish a meal before it is time to get up and make her speech. She will lift her fork, then put it down again to make another point, leaving almost all of her meal untouched.

Welcome to this short tour of Montmartre. Montmartre is an old {#blank#}1{#/blank#}(村庄)in the north of Paris. From here,I'm sure you will learn s{#blank#}2{#/blank#}special about Paris.

Walk out of Abbesses station and across the street is a small {#blank#}3{#/blank#}(花园)with the famous Wall of Love. On the wall you can find "I love you" in 250 languages. Walk up the street and {#blank#}4{#/blank#}(放松)yourself at Le Bateau-Lavoir. Many famous artists, such as Picasso, lived and worked here d{#blank#}5{#/blank#}the late 19th and early 20th centuries.

Turn right and walk along the street to the Place du Tertre. Every day, hundreds of street artists paint pictures and {#blank#}6{#/blank#}(卖)them in this square. Opposite the square is the Church of Saint-Pierre. Built in {#blank#}7{#/blank#}(四月)1147, it is one of the oldest churches in France. After visiting the Church of Saint-Pierre, go to Sacré-Coeur, a big white church on the top of the Montmartre Hill. Standing here, you can see most of Paris on a c{#blank#}8{#/blank#}day.

Now you will have two h{#blank#}9{#/blank#}of free time. Maybe you can have a cup of coffee in a café and take a {#blank#}10{#/blank#}(慢的)walk around. Enjoy yourself and see you later!

In some cities, we can see more and more people riding sharing- bikes. It's very convenient to use the bikes if you have a smart phone. First, you have to download such an APP on your smart phone. Then, what you need to do is to find a nearest bike through the  APP, scan the QR code on the bike or connect your phone with the bike over a Bluetooth   wireless connection. You will find the bike can be unlocked itself easily. Then, you can enjoy your trip. What's more, the greatest advantage of bike- sharing is that you can easily find one and never worry about where to park it. The cost of riding depends on the time that you spend. Normally, every hour you ride, you need to pay one yuan. It doesn't cost so much, does it?

At the same time, some people park the bikes in their own homes, Besides, some people don't value the bikes. Now service companies are trying to solve the problems like being stolen.

Technology and science have changed our social lifestyles. We have to say bike- sharing brings us more convenience without doubt, And we also hope that people can not only enjoy it but also put it to good use.
