【范文】
Micro-blogging is no longer a strange word. More precisely, it has become part of our life.
As for me, many factors contribute to the widespread of Micro-blogging. First, it is very convenient for people to express their instant feelings at any time. Second, it provides a chance for people to release their inner stress. By revealing their heartfelt emotions on the Micro-blogging, their friends may also know about their conditions and can offer in-time comfort.
However, Micro-blogging can also be potentially dangerous as it may give away peoples privacy and other significant information.
All in all, Micro-blogging provides us comfort and also inevitably some concerns. We should be careful while using it.
【点评】
第一段直接切入主题。首句在说明微博越来越流行时没有用肯定句micro-blogging is more and more popular, 而是用否定句的方式负负得正。
从第二段开始阐释流行的原因。Contribute to是固定词组，表示为作出贡献，其对应的名词是contribution。第一个原因是微博方便人们在任何时候表达他们当时的感觉。这里通过at any time和instant feeling突出了微博和传统博客的区别。第二个原因是微博可以减压。此处release表示释放，除了跟release pressure, release stress, 还可以跟release news。
第三段描述了微博的弊端，give away表示出卖，同义词有betray。最后一段是作者的对微博的态度，在充分肯定微博积极意义的同时提醒人们要谨慎使用微博。
