　　Nowadays,more and more hi-tech tools, such as calculator,computer,smartphones,etc, appear in our daily life.We use them wherever and whenever we are, so that our life becomes easier and more comfortable than before.

　　However, does anyone think about what problems science and technology have caused to happen in this world? To some degree, it's more serious than that we consider. We human indeed use them to improve our living standard, but on the other hand, we are becoming lazier, more reliable than we used to be. All day long those hi-tech products accompany us,then we have either no space or time to think, as well, communication between each other decreases, and what takes place of it is the huge indifference and gap among human.

　　To solve these problems, we should in no time take measures to do with them. Firstly, communicate with others and think on your own more. Secondly, decrease the times you use hi-tech tools. For the advantages of technology, we should absorb, at the meantime, be independent and abandon the short-comings. Thus, we could combine technology and human progress much closer and not lose ourselves in this modern society.
