Expository Essay顾名思义也就是说明文，很多同学都搞不清楚Expository和Argument的区别，常常把两者混为一谈。HotEssay用一句话来帮助大家区别它俩，Expository 是为了让你的tutor了解情况、明白事理、知道真伪，一般不确立什么论点，而Argument是需要确立论点，而且还得好几个。所以大家知道区别了吧，那么本文中HotEssay就给大家分享一份Expository essay写作指南，包括从草稿部分到最后的结论部分都会给出写作指南，在文章的最后也会给大家附上一篇范文，以供大家结合指南参考消化。
1.草稿部分的写作
首先要清楚expository essay是没有争议和论点的，只需要描述别人的观点或者一个事件或情况的表述让读者知道就可以了。
写作指南：
a. 时间充裕的同学先写草稿，时间紧迫的同学可以大致写一个outline就可以了，这个过程可以帮助大家整个写作过程更加容易组织语言和富有逻辑条理；
b. 为expository essay确定一个比较容易入手的题目，HotEssay建议不要太宽泛，也不要太狭窄；
c. 确保你的tutor熟悉你选择的题目或主题；
d. 找到事实基础来支撑你的expository essay；
e. 尽管说明文的目标是表述事实，但有趣的叙事会让读者更加愿意阅读。
2.介绍 (Introduction)部分的写作
一个良好并且组织正确、表述清楚的Introduction应该秉承由一般到具体的写作手法。
写作指南：
a. 对于expository essay来说，一般文章的hook sentence就需要表述清楚行文方向和梗概；
b. 论点语句非常重要，你的目标是尽可能清晰的阐述你要准备阐述的事实概况；
c. 确保你的总体论点（概要）对你的全篇论文有效；
d. 如果老师分配了一个主题，那么不要在第一句话中重申主题。
3.主体 (Main body)部分的写作
HotEssay建议使用三段式（Three-paragraph）格式来阐述事实，结构比较清晰。
写作指南：
a. 各个段落表述的内容和信息均匀分布；
b. 针对你的老师进行有效清晰的使用数据表述内容；
c. 确保各个段落以恰当的方式衔接并且逻辑清晰；
d. 确保各个主题间转换清晰明确；
e. topic sentence极为重要，它们意味着一个新的思想和内容的开始。
4.结论 (Conclusion)部分的写作
结论是文章最后一段，写结论的时候要结合introduction去写，避免发生头重脚轻的情况。
写作指南：
a. 论文的主题论点和阐述的主要信息应该在结论段落进行重申。此外，它应该是整篇论文的一个有效的结束和闭合，不要阐述或涉及新的问题或观点。
以下是一篇范文，大家可以参考学习一下：
In my expository essay I expose the threats that currently exist with regards to your mobile device. These threats are aimed to include threats to your personal data and how much money you have, and they all involve your mobile device and/or mobile phone. In my expository essay I expose these threats and give some advice on how to avoid having your data stolen and how to avoid losing your money.
“In-App” purchases are a threat to your money
Some apps and games allow you the ability to buy within the application itself. They are called credits or points and are known as “in-app” purchases. They are done without going through the traditional ordering process. There is a risk of spending money without being fully aware of how much. Children often make purchases when they are playing with their Smartphone. You may lose more money than you expect if you make in-app purchases. Disable “in-app” purchases on your phone. Turn on the auto-purchase function only for apps you know you are not going to overspend on.
Only buy apps from official app stores
Only buy and install apps that come from official app stores. These are apps that are checked prior to being loaded. Plus, if customers complain the apps are removed from the App Store.
Malware and viruses may take your money and steal your personal information. Buy from app stores where only safe apps are provided. If you buy from third-party websites, then there is a chance the apps are infected with malware or viruses. These programs may infect mobile phone and steal their data. They communicate silently and without your authority or and send chargeable SMS messages to premium rate numbers, which costs you money.
Watch out for free apps.
Be especially careful with free apps and associated advertising links. Many free apps are financed by advertisements. They often have ways of extracting your information and many times make it easy for you to place an order or offer information without being fully aware of it.
In addition to the reputable advertising offers, there may also be cases in which hidden orders are written via adverts you click. There may be plenty of legitimate adverts, but it is the dangerous and illegal adverts you have to watch out for. Before you buy your apps, ask yourself if you really need it or really want to try it. Read reviews of the apps you want before you buy them and do not install Apps that are poorly rated, even if they are featured on a well-known app marketplace.
Unnoticed transfer of personal data
Studies show that many apps transmit sensitive data about users. For example, an app may transmit your location data, your social media profiles and even your bank details. The sad part is that many of the apps will get you to agree to this first without you knowing, which is why they are so dangerous with regards to your personal details and your money.
Turn off Automatic Updates.
If you use a data plan with limited data volume, be aware that apps consume your Internet data. You can turn the “Automatic Updates” off and only allow updates when you have enough data or when you use a Smartphone with a Wi-Fi connection.
Conclusion
I have found that there are a lot of threats to mobile phones (cell phones), there are lots of threats to the amount of money you have and to the safety of your money and your personal data. In my essay I feel I fully exposed the biggest threats and feel that I gave very effective advice so that people may avoid over spending, avoid viruses, malware and avoid having their money and personal data/details stolen.
