今年6月上旬,我们几个昔日的同班同学相约去加拿大旅游,其首都温哥华的环境卫生给我们留下了非常不错的印象。每天吃完早饭,我们都要到各处走走。走在马路边的人行道上我们看到,温哥华的街道笔直而宽敞,住户周围都有绿地围绕,树叶飘落了,有清洁工定期用便携式吹风机来处理,非常省事。他们把落叶吹到马路上,然后由三辆车来对落叶和垃圾进行机械化处理。第一辆车负责把路上停放的车拖至干净地方,便于吸尘车清扫。第二辆车则是吸尘车,这是一种大马力的车,只见它开动后,连扫带吸,所到之处,马路被清扫得干干净净。第三辆车是洒水车,将刚清扫的地方再进行清洗,干净得像我们住家的地面。通过这样三道程序,路面怎能不干净呢?清洗完毕,第一辆车再将被拖走的车拖回原处。这样人性化的操作,不免让人想起我们自己:我们国内能做到这样吗?首先是我们没有那么多的机械,其次是环境太差,许多人又不会自觉保 In early June of this year, several of our former classmates made a trip to Canada. The environmental sanitation of Vancouver, the capital of the country, left us with a very good impression. After breakfast every day, we have to walk around. Walking on the pavement on the side of the road we can see that the streets of Vancouver are straight and spacious. There are green areas around the residents and the leaves are falling. Some cleaners regularly handle them with portable hair dryers, which is very convenient. They blow the fallen leaves onto the road and then three vehicles to mechanize the leaves and the trash. The first car was responsible for dragging the car parked on the road to a clean place for cleaning the car. The second car is a vacuum cleaner. This is a high-powered vehicle. After it is started, it is even wiped and smoked. The road has been cleaned and cleaned. The third car was a sprinkler. It was cleaned immediately after it was cleaned, and it was as clean as the floor of our house. Through such three procedures, how can the road be unclean? After the cleaning is completed, the first car will drag the towed car back to its original location. This kind of humane operation can not help but make people think of ourselves: Can we do this in China? First, we don’t have so many machines. Second, the environment is so bad that many people do not feel safe.
