With the development of science and technology ,smartphones become more and more useful in our life .They make our life more convenient.

However everything has two sides .Smart phones bring us convenient  ,but they have disadvantages at the same time.

For example, using smartphones will affect children's study.Children bring their phones to school ,even though the smartphones are forbidden to use at school ,they will attract children's attention and make them lazy .

In my opinion ,smartphones are not only great tools for communication but also are the weapons which can hurt us a lot.So we should use them well to make our life more convenient.
