托福独立写作素材：勒索病毒软件案例

　　独立写作有哪些困惑

　　说到独立写作，很多童鞋可能都有些无从下手，一是拿到话题不知道从何开始，二是想到了观点但是不知道如何去说明或者例证。

　　尤其是托福考试用大写字母标出DO NOT USE MEMORIZED EXAMPLES之后，大家更是措手不及，以前背的一些名人事例好像都不好用了，那么我们该怎么办呢?

　　其实大家都知道是缺乏素材积累，却不太明白怎么开始，而素材积累往往就来自于身边发生的事情，不管大事小事，总是能写进作文里。

　　如何积累热点事件素材

　　最近几天充斥网络世界的新闻之一，大概就是WannaCry2.0事件了吧。

　　作为一个勒索软件(Ransomware)，通过网络病毒的形式侵入一些用户的电脑，勒索用户的比特币(bitcoin)。很多同学都听说了这个事件，也和小伙伴吐槽过，而大家通常是停留在吐槽的表面，并没有看到这个事件的本质。

　　揭开新闻事件的面纱，其实和我们独立写作最贴近的部分就是科技这把双刃剑，在互联网发展迅速的今天，人们在享受着它带来的便利的同时，也有一些副作用损害着人们的利益。

　　所以我们科技类话题的作文，在考虑利弊分析的时候通常有一个万能理由---科技的进步也会给人们带来弊端，那么在这个事件的支撑下，轻松说明互联网的负面影响(negative impact)---勒索软件(ransomware)给我们带来的问题。

　　案例分析：科技带来的弊端

　　In terms of life quality, there is no question that technology has revolutionized our life. Yet we still cannot ignore the problems coming along with the progress. While we are enjoying the convenience of searching information online and the notifications from the calendar, we might receive an email accidentally sent by someone with evil intentions, which could cause some problems.

　　A ransomware, WannaCry2.0, has been passed around online recently. People who have received this email and clicked the link would find that their important documents stored in the computer are locked and they are blackmailed for large amounts of bitcoin, a kind of virtual currency. In order to get these documents back, people have no choice but to pay bitcoin or the real money. As a result, these victims could lose thousands of dollars, some of which would even lose all the important documents no matter they choose to pay or not.

　　Imagine that a to-be graduate who has already finished the final paper suddenly lose his paper, or a doctor who is going to do an operation suddenly lose all the information of his patients. You can understand how bad the consequence is caused by ransomwares such as WannaCry2.0.

　　所以呢，大家也可以试着注意周围发生的新闻或者事件，按照话题进行分类，存在自己的语料库里，这样在考场上才不会无话可写哦~
