手机在学生中的普及使用，既有利，也有弊。利的方面是，中学生用手机，一是方便家长和学生联系。家长想了解孩子在学校的动向，随时可联系掌握，同时，也便于对子女嘘寒问暖。二是有利学生与老师沟通。有时课业上的问题，生活中的难题及一些不方便与老师直面交流的问题，通过手机交流免去了胆怯和尴尬。三是有利于同学间交流。有不愉快的事或烦恼，可以与同学发发短信，聊聊知心话，既可聊一些中学生成长过程中的心里话，又能加深同学间的友情。但中学生使用手机，其“弊”也显而易见。其一，学生使用手机，先不说不利学生的学业，单说课堂上手机突然响起，既扰乱了课堂秩序，分散同学们的精力，又影响了老师讲课情绪。在寝室使用手机，既影响同学休息，又耽搁自己的业余活动，铃声还成了扰寝的噪音。其二，一部分学生考试时利用手机作弊，影响了考试的公平与公正。其三，对心智还不成熟的中学生来说，对手机上的*短信、网络游戏，难以抵挡*，一旦沉迷其中极易荒废学业，德颓才丧。其四，手机属于贵重物品，对于学生来说，保管不妥，后患无穷。

The consequences of cell phone use
Cell phones are a source of electromagnetic fields, radiation which createschange in anything it comes into contact with. EMFs emanate from mobile phonesand because of how phones are used, these EMFs come into direct contact withthe brain.
More than a dozen studies have linked using a cell phone for a long period oftime -- ten years or more -- with a higher incidence of brain tumors andacoustic neuromas. These critical diagnoses are even more common when phonesaren't switched from one side of the head to the other when engaged inconversation.
Other adverse health effects include:
• Evidence of leukemia, breast cancer and other cancers.
• Neurological concerns and changes in the nervous system.
• A much higher risk of salivary gland tumors.
Supporting studies
A study from the Medical University of Graz in Austria showed that cell phoneuse negatively affects sperm quality in men. A similar study from 2009 examinedmen in the height of their reproctive years and found infertility and theability to father a healthy baby were compromised by cell phone usage.
Cells phones are also a source of perfluorooctanoic acid, a harmful chemicalwhich has been linked to heart disease, cancer and femalereproctive/developmental damage.
Cell phones are not the only problem. Cell phone towers, as well as otherwireless devices, are responsible for contributing non-ionizing radiofrequencies into the environment. Both the World Health Organization and theInternational Association for Research on Cancer have classified theelectromagnetic fields emitted by cell phones as a 2B, possible carcinogen. Thetowers and the phones themselves are constantly emitting microwave radiation.Even when cell phones are not in use they are putting out EMFs.
