private cars have become an important aspect of people’s life in many parts of our country, especially in large cities such as beijing, shanghai and guangzhou. while they bring much convenience to people, they are also widely criticized.
there are some arguments for owning private cars. in the first place, cars allow people to move around freely, which greatly improves our living standard. we can easily drive cars for sightseeing on weekends. in the second place, cars are a comfortable way to travel, especially in bad weather. last but not least, the car industry can boost economy by creating many job opportunities in production of steel, rubber, glass and so on.
however, there are also many good arguments against cars. first of all, they pollute the environment by emitting harmful gases and giving out loud noises. in addition, cars cause a large number of traffic accidents, which bring great misery to the victims’ families.
as far as i am concerned, we should limit the number of private cars by providing better mass transportation and better service for the people. everyone should sacrifice his or her own interest for the common good of the society. (194 words)
