Travelling is a very good activity. When you get tired of your work or study, and when you have free time, you can go to a beautiful place to enjoy the beauty(美丽) of nature(大自然) or other cities. You can take in fresh air, meet different people and make friends with them. It's good for your health to do so.

    But sometimes, travelling is not an enjoyable thing. For example, the weather can be changeable. There may be rain when you travel. You may catch a cold or be ill while travelling. The worst(最糟糕的) thing is that the thieves may steal(偷) your money. All these may happen to a traveler.

When you go on a trip, you must get everything ready. Firstly, you must have clear information about the weather. Secondly, ask a friend to go with you so that you can help each other. Thirdly, you must be careful everywhere and try not to cause accidents（引起事故）. If you do these, you will enjoy your travel.

    With air pollution making much difference to many of Chinese cities, parents are calling for the installation(安装) of air cleaners in classrooms. There has been much debate over whether air cleaners should be used in China's schools. Some parents have donated cleaners to their children's classrooms, while others raise money together to make the purchase(购买). “Our school bought air cleaners last year. We did a little fund raising, with each parent throwing in several hundred for that,” said one parent.

    However, the idea of installing air cleaners for all the classes has been refused by some schools. Liu Liangcheng, vice-principal of Beijing's Taipinglu Primary School, says installing air cleaners bought by parents may lead to problems. “We have refused air cleaners bought by parents before, as there are clear and strict rules against educational fees. We can't just break the rules here. And without standard guidance (指示) from local authorities(权威部门), it is hard to decide on the brand of the cleaner, installation and even safety of the device(设备).”

    Moreover, experts say air cleaners can cause other health problems. Deng Gaofeng who works for the China Academy of Building Research says. “ In the classroom, if we keep windows and doors closed, the concentrations (浓度) of CO₂ will double from 1,000 PPM to some 2,000 PPM. According to national safety standards, the highest level should not be more than 1,500.” In addition, experts say air cleaners on the market are mostly designed for homes or offices. Evaluation(评估) is needed to know whether they are suitable in classrooms.

    It seems whether air cleaners should enter China's schools is an ongoing question. It still requires a more detailed plan.

    Have you ever taken photos by using mobile phones with selfie sticks (自拍杆)?{#blank#}1{#/blank#} 

    However, a pair of US artists from New Mexico, Arie Snee and Justin Crowe believe they have invented a better one and they call it "selfie arm". {#blank#}2{#/blank#} It makes those people in the pictures seem to be holding hands with a love one.

The product, at present, just an art project and a model, conveniently provides you a welcoming arm. {#blank#}4{#/blank#} The pair say they are fascinated by these new ideas.

    The "selfie are" is made of fiberglass. {#blank#}5{#/blank#}
