　　Mobile Phones in the Class

　　Given is an interesting cartoon：writing on the whiteboard，the teacher says the formula is SO important that it will be Oil the test.Meanwhile，all the students use mobile phones to take the picture of the formula instead of taking notes.The picture demonstrates that mobile phones are quite prevalent in the class.

　　There are mainly two reasons.On the one hand，in contrast to writing the important points down，students tend to use mobile phones to remember things， for taking picture is extremely easy.0n the other hand，many students usually play with their phones even in the class，so they find it much convenient to use their phones to take photos rather than to pick up pens again.

　　In short，the popularity of mobile phones in the class proves that students pay less attention to study.Both schools and parents should discourage students from overusing mobile phones.
