Some days, don't you think, "Wouldn't it be nice if the laundry would just do itself?” Self-cleaning clothes may sound crazy. But Australian researchers have found a way to make something like this possible!

    A team at RMIT University in Melbourne, Australia, found a way to put special nanostructures (纳米结构) into clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down the dirt and stains (污渍) that don't belong on your clothes.

    The nanostructures don't break down the actual clothing because cotton and the other clothing materials are too strong to be broken down. According to CNN, the researchers cover the clothing in a solution made of silver and copper (铜) nanostructures. All it takes is 40 minutes of sunlight and your clothes will look as good as new.

    So if you spill on yourself during lunch, you can step outside for a walk, and it will be clean by the time you go inside. It not only makes your life easier, but it can also be good for the environment.

    According to the US Department of Energy, the average load of laundry uses about 25 gallons (about 94 liters) of water. Water is a very important resource, so using less of it to wash clothes is better for the environment. But one of the scientists at RMIT University knows more needs to be done.

    “There's more work to do before we can start throwing out our washing machines,” said Dr Rajesh Ramanathan, “but this is a strong foundation (基础).”

    So what's the next step? Ramanathan wants to either start selling the solution by itself or convincing (说服) clothing makers to treat the clothing with the solution while clothes are being made.

On December 9th, 3:50 in the afternoon, many students in China watch TV. It is a very interesting science class from the space station(大空站). They all like it very much!

Zhai Zhigang, Wang Yaping, and Ye Guangfu are the three teachers. And Wang Yaping is the only woman teacher. She is great fun!

First, she says hello to all of the students. Then she lets the students have a look at their "rooms" in the space station. She gets an apple from the fridge（冰箱）．She says, "This apple is in the space station for a long time but it is really fresh. In her class, Wang Yaping helps the students to know much about water in space. She puts a ping-pong ball in the water. The ball doesn't go up but stays in the middle of the water. It is really interesting! Things in the space station are not the same as we know. Many students ask questions about space science. They are happy to help them.

Wang Yaping has a flower. It is from her daughter. She is only five now. She watches her mom in the space class, too! After one hour, the space science class finishes. Wang says, "All of you are flowers of China. One day you can come to space yourselves and find new things about space!"

Gardening is very popular in many places of the world. It brings us sweet flowers, fresh fruit and vegetables. But you can get more from your garden. 

Gardening helps to keep healthy. Today's people sit indoors for too long and don't get enough exercise. When you garden, you have to move around. It's a good chance(机会) to exercise your body by watering the flowers or doing something else. Also when you are in the garden, you can feel the warm sunshine. This means you are getting more Vitamin D. It helps your body use calcium(钙), which is necessary to keep your bones(骨骼) strong. 

Gardening is a great activity to do with children. It gets them off computers, televisions and smart phones. Gardening can be a great teacher to teach kids about nature and healthy eating. It can help them to understand the meaning of hard work. 

Gardening is a great way to meet people and build a good relationship(关系). When you are gardening, you are outdoors, so it is a great time to talk with your neighbors. You may talk about your hobbies and interests. People always enjoy showing others what they are growing and enjoy sharing advice and stories about their gardens. 

 Xinjiang lies in the northwest part of China. Its many cities are popular places for tourist such as Turpan, Kashi, Aksu and the provincial capital(省会) city Urumqi. As Xinjiang is a place with quite a lot of minority groups(少数民族), there are some local traditional festivals that we might not quite know of.

 Grape Festival is one traditional festival in Turpan. It is the hometown of grapes. This world-known city welcomes the local people as well as international friends to celebrate the festival together. This festival is not just a celebration of Turpan's most important agricultural product(农产品), but a good chance to enjoy the local way of life. During the yearly Turpan Grape Festival, traditional singing and dancing activities are held. Besides, travelers may visit the grape, melon, and fruit streets.

 Turpan Grape Festival is a special event to commemorate the Silk (丝绸) Road so that people will not forget about this road. Turpan is famous as an important point of the road.
