The Most Helpful Invention
There are a lot of inventions in the history. Some of them play an important role in people’s life and some have greatly changed the world.
In my opinion, I think the most important invention is the car. First, people used to travel by train or by plane. But now, they can go any place by car. Second, when holiday comes, they can visit their family and friends by car. Third, they can also go to many places of interest to enjoy themselves.
In a word, I do agree that cars are the most important invention.
