There have been a lot of changes in the city's transportation. Nowadays, there are more people and as a result, there are more cars, more underground subways and more bikes. During rush hours, it is hard to get on the bus or the subway and even harder to get off after more and more people get on. Bikes are the better means to get around the city because they are easy to park. Besides, they don't cause as much pollution. There are many people who drive in violation of the traffic rules, so it is important to keep ourselves safe on the street.
城市的交通有很大的變化.現(xiàn)在,人越來越多,所以有更多的轎車,更多的地鐵和更多地自行車.在高峰時間,上公交車或者地鐵很難但是當更多的人上車后下車會更難.自行車是比較方便的在城市里穿梭的交通工具因為他們很容易停放.此外他們不會引起環(huán)境污染.有很多人違反交通規(guī)則行駛,所以在街上保護我們自己的安全是很重要的.
