  The usage of Internet becomes one of the most controversial topics in the society. As a college student, I believe Internet is beneficial to me more than the way it harms me. There are many advantages for using Internet. First, I can best use my time to find information online instead of going to different libraries. Also, the information can be dated back in decades ago. It is very helpful to use those information as reference and historical proof. In the library, it is hard to find so much old information. Another advantage to use Internet is that I can stay home and have a lecture online. It is much more convenience to me because I can stay warm to have class in the winter time instead of spending two hours on the bus and physically attend class. In addition, Internet provides me a better way to communicate with my friends and professors. I can get response from my professor in a few minutes instead of waiting outside of his door for hours. Some of my friends are living in a foreign countries, I can simply just drop him an email whenever I can and get a message from him very quick. It is much better than waiting for letters. Also, the email will not lose while the letter might be losing in the process of delivery. However, there are also disadvantage of using Internet. For example, I might spend too much time on the Internet to concentrate on my study. Also, there is a chance that I am cheated because of the Internet purchasing. Last, Internet has lots of information, both helpful and harmful. There might be too much tempatation that I will access some of the harmful information I can on the Internet. Even though the usage of Internet has both positive and negative effect to me, I still consider Internet is a symbol of technology development. I believe I can use the Internet very well as long as I know how to control myself.

  预防电器火灾,包括四个方面的内容:一是电器的选择,二是导线的选择,三是安装和使用,四是不要擅自使用大功率电器。对电器应选择名牌厂家生产的合格产品,安装要符合规定,使用要按说明书的要求,不乱拉电线。教学工作必须使用较大功率电器时,2019年太子报最新彩图。要请专业电工人员安装专用线路,不得与其它电器同时混用。平时不用电时,要断掉电源。下面列举一部分常用电器的火灾预防:

  室外天线要有避雷装置和接地设施,用室外天线雷雨天不要开电视。不看电视时要切断电源。

  不要让电机进水短路,不要因衣物多或硬物卡住电机而造成闷机现象导致发热着火。

  电熨斗温度很高,能引燃一般的物质。所以电熨斗使用时一定要有专人看护,通电时间不宜太长,用完一定要断电,放在隔热的架子上自然降温,防止余热引起火灾。

  注意消除隐患。微机室电气线路、设备多而复杂,材料多为易燃性材料,人员聚集、流动性大、管理混乱等问题都是隐患,应有针对性地落实防范措施。

  白炽灯当电流通过时,可产生2000-3000摄氏度的高温而发光,由于灯泡中充满惰性气体可以导热,所以玻璃表面的温度也很高,功率越大,升高的温度越快,白炽灯与可燃物距离应大于0.5米,灯泡下方不应放可燃物。晚间看书学习时,不要将照明灯具放在被褥上。

  烟头虽小,可危害性大,它的表面温度在200—300摄氏度之间,中心温度可达700—800摄氏度左右,一般可燃物(如纸张、棉花、柴草、木材等)的燃点均在130—350摄氏度之间,都低于烟头的温度,所以烟头可以引燃大部分物质,因此乱扔烟头很容易引发火灾。吸完烟后应将烟头“掐死”,放在烟灰缸或金属、玻璃等不易燃器具内,不要随意乱扔,更不能在禁烟场所吸烟。
