When we are using the smartphone,we usually bend our neck. If we often do like this,our spine will get hurt.
With the development of smartphones,more and more people are using it every day. Some people stare at the tiny screen on his hand and don’t make any attention to other people,even they’re sit together. It’s just like a wall that built between the two people,they seemed like very close but actually they were parted.
Some people spend a lot of time playing video games or chatting with friends,but time is precious and it slipped away fast.
