The BadCell phones are a distraction – The students use short message service (SMS) and not everyone remember to turn off their phone during class. Cheating – Students can share information during exams. They can also store any information they want on their cellular phone. Invasion of privacy – Camera phones are very popular，and they are sometimes used in an inappropriate way in schools，for example in bathrooms. Harassment – Text messaging is used as a form of harrasment or bullying. Stealing – Mobile phones are usually worth over $100 and not every family can afford to buy one for their children. These two factors often lead to cell phone theft. One could argue that cheating has always been and will always be and that and bullying existed before cell phones came to schools. Cell phones only emphasize existing issues.The GoodFeeling of security – Knowing that your children are reachable anytime is quite reassuring for a parent，especially after events such as the Columbine shooting and the September 11th tragedy. It brings families together – Families don’t seem to have much time to spend together anymore. With overtime and after-school activities，having the ability to communicate with any one of your family member helps bringing families together. Cellphones are convenient – Everybody is more busy nowadays. Students are involved in activities after school，and practices and meeting time tend to vary a lot. It is very convenient for a student who does not have access to public transportation to call their parents for a ride when they need one.
告诉你 不学你会后悔的！当你学完后你会发现你小学到大学那英语都是白学的 除了和老外随便能勉强说几句 其他简直就是狗屁不通！BEC不仅仅是我们中国人眼里学下语法 背下单词那么回事，他涵盖了很多的外国文化背景 知识 风俗 工作方式 等等 小到怎么请老外吃饭（这也属于商务活动）。我个人学下来觉得最最好的 重要的就是 我的理解力现在很强大！你有的时候会发现 单词全懂，但是句子就是不懂 完型 阅读就是看不懂。对 这就是长期以来我们中国人教中国人英语的原因 根本不会去理解 作者 或者和你说话的人到底是在说什么。比如老师在高考是教我们 阅读理解去全文中找 只不过是换了个单词。这就是坑爹！你也会发现很多英语专业 什么专8都过了的人 连和老外说句话都说不清楚。BEC就完全不一样 他不要你去看表象 而是去推论 判断！再者 如果你不想考试 只是为了提高 我真的觉得BEC非常适合你，因为上面我已经说过了。BEC是商务英语 简言之 侧重商业的知识 介绍 说明。怎么管理人 怎么经营 怎么发展之类的 所以是具有一定专业化难度的 不是CET-4 生搬硬套的叫你选几个词 填几个空（无专业化可言）BEC虽然是商务英语 但是他是外国一些高等学府对你英语水平的一个认证。就如咱们中国不是也有汉语学家之中概念吗。你只为了强化英语 可以去参加BEC初级 在国外定义为 能够基本正确使用英语的人 （是英语，不是单纯的商务英语） BEC中级 具有一定水平的英语使用者 外国人把他也称作“第一个英语证书”相当于中国的大学英语4级证书（不过是外国的） BEC高级 叫做专业级的。就说到这里 还有 BEC是只在一个工作场合或情境下的英语应用 不是跟你介绍什么是道琼斯指数 汇率浮动点的 单词在日常生活中都很常见 背单词不用去刻意的背那些鸟的专业名词！
