In the UK, bus journeys are very common. Buses are often convenient（便利的）for the people who live or work in the city center. Passengers can avoid heavy traffic and not have to pay for the parking. However, taking the bus is just a necessary but boring part of life: they get on the bus, pay for it and sit or find a place to stand when it is crowded. Everyone seems sad and bored.

 In Latin America, however, bus trips can be wonderful. For a start, films are showed on the buses between cities for passengers to have fun along the journeys. Local buses do not show films, but drivers usually turn on the radio and it can be great for passengers to listen to songs and get relaxed.

 Even better than films and music are the sights and sounds on the buses. Local buses always go to parts of the town that passengers would not visit by themselves. There passengers can see shops that they have never heard about. And they can also see other cultures of the town from the windows of the buses.

Besides, passengers' luggage（行李）is also interesting. It is common to see a happy dog's head getting out of somebody's bag or a lovely chicken“speaking cheerfully”under somebody's arm. Once on a bus in Peru, a farmer even tied a sheep to the top of the bus. It was quite surprising.

 In all, taking the bus in Latin America is really fun and unforgettable.

    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.
