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 40minutes 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 25gallons (about 94liters) 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.

People at home keep asking me, "Is it hard to learn Chinese? Why have you learned it so well?" Well, there's one thing that makes Chinese easy to learn: there are so many people to talk to. You've probably heard that it's the most spoken language. Today it's also one of the most written languages online. And with so many Chinese people interested in learning English, it couldn't be easier to find a friend for language learning. You just have to know where to look for them.
The really good place to look for them is QQ. QQ has the same status(地位) in China as AIM (AOL Instant Messenger) does in the US. It is reported that at any moment, up to 9,000,000 people are using QQ. They're at work, or in a web café(网吧), or at home, and the information of the users can be found. If you sign on with your address set to "abroad", you'll soon find that many thousands of them are interested in speaking to you! This is a great way for you to learn Chinese, and for them to learn English. I think that it's a very interesting way of cultural contact(文化交流), too, for ordinary people from around the world to be able to have one-on-one contact. In the first paragraph(段落), the writer tells us ___________.
A.why his family members want to learn Chinese |
B.where you can find people to talk to for language learning |

Japanese children are so happy because they have three festivals each year. Including Boy’s day, they have Girl’s day and the 7-5-3 Festival.
May 5th is Japanese Children’s Day. But since the festival is mainly celebrated by boys, it is usually called Boy’s day. On Boy’s day, children don’t have to go to school. Each family with a boy hangs up huge carp-shaped flags(鲤鱼旗). The flags are usually with three colors: black (standing for the father), red (standing for the mother), and blue (standing for the son). 1) Japanese parents believe that the flags will bring their boys good luck and give them courage and power.
Girl’s day is a girls’ festival on March 3rd. It is also called the Doll’s Festival because on that day, families get a set of dolls at home for their daughters. It is celebrated because the parents want their children to be strong and healthy.
2)The 7-5-3 Festival is for________aged three, five and ________. Japanese people think that these three ages are the luckiest ones in one’s life.

Last week was Road Safety Week at Jason's school. All the students had to take part in a talk on road safety which was given by a police officer. The following is what the police officer said. “Most traffic accidents shouldn't happen. They happen because people are careless. A frequent cause of traffic accidents is speed. Some people drive too quickly. This means that if they have to stop suddenly, they cannot stop quickly enough to avoid (避免)hitting other vehicles (车辆)or people. You need to remember this when you are crossing the street or walking along the sidewalk.”
“It's not only drivers who cause accidents, however. People on foot-pedestrians, and bicycle riders often cause accidents, too. Pedestrians sometimes walk out into the street without looking. You should always look on both sides before stepping into the street. ”
“Do any of you ride a bike? Bicycle riders can cause accidents by changing directions suddenly or without warning other road users. Before you turn left, for example, you should check behind you to make sure there aren't any cars, trucks or buses coming. You should show with your left hand to tell that you want to turn left. You should not turn until the street is clear. ”
