In China,people's living conditions in .the cities have changed a lot in the ways of transportation in the past fifty years.
A survey shows that the number of people riding a bike or walking is always decreasing. In 1974,more than 50% of people traveled to work on their own bikes,while by 2014,less than 20% of travelers preferred cycling or walking to work. Now the number becomes much smaller.
At the same time,there was a large increase in the use of cars. In 1974,very few people had a car. By 1994,about a quarter of travelers drove to work. This increased again,until 2014,about one third of travelers drove to work.
What has caused these changes? The main reason is that people's living conditions have changed greatly. With the increasing number of people going by bus or car,fewer and fewer people would like to be cyclists or walkers.
As people enjoyed the convenience (便利) and speed of buses and cars,they are less likely to have patience and interest in cycling and walking. In the future,with the development of science and technology,more changes will happen in people's everyday lives.
