Answer 1

One possible version ：

Car-free Day was launched  in our city and 107 other cities on September 22 ， 2012 to encourage people to take public transport ，
ride bicycles or walk instead of driving private cars 。 The campaign has gained much support all over the country and has raised awareness among all people of energy saving and environmemtal protection.It’s a real suc-cess.

With the development of the economy more and more families have bought private cars thus leading to much heavier traffic problems and serious air pollution.Therefore I think it’s necessary to launch such campaigns.And I hope more cities and their residents will take part in this type of activity.
