我想申请美国读研，方向power system，对于申请难度，开设本专业学校，还有要怎么准备求各位大神指点 谢谢

要是你不能自己去学校查的话，那就咨询一下留学公司吧。我为什么要建议去咨询公司咨询，是因为我之前为此准备过，也咨询过很多公司，对于这个行业有些了解，特别是自己查不到很多自己想要的信息的话就借助专业机构，我对比了下，太傻的专业度是最好的，所以建议你去咨询下。

你的情况也不说。。。去哪个国家啊、是想上还是已经有了AL成绩了 这怎么回答。。

To Whom It May Concern:
As Principal of George Mason High School I am delighted to recommend to you a stellar member of our teaching staff, Mr. Samuel Cohen, and to write this letter on his behalf. Sam has taught American History at the school for three years. He is one of our most popular and effective instructors and has already won several teaching awards.
He came to us directly upon completion of his bachelor’s degree, but immediately settled in as if an old pro. Sam is a master of all of the ingredients of successful teaching, especially the ability to inspire.
This gentleman is highly professional in both dress and demeanor. To my knowledge Sam has never come to work without both a suit and tie, more times than not a bow tie. The majority of others at the school, both teachers and students, dress differently and lean to more informality. Never once, however, has Sam’s manner of dress elicited the slightest comment. Why? It is simply because Sam’s attire seems entirely natural given his dignified comportment.
That comportment in turn is driven by Sam’s love and respect for American History. Sam views himself as the messenger for something serious and important, and this is reflected in the way he teaches and in the way his students respond.
Reaction to Sam’s classes has been overwhelmingly positive. So much so that more than once it has been reported to me that study hall students have been spotted lingering outside the door to Sam’s classroom listening to his lessons.
Sam’s impact has even been felt outside the school with the parents themselves. His section on the importance of voting has inspired students to cajole their parents to register to vote. Several have mentioned this to me at parent-teacher meetings. One even called the school to have me pass on their thanks to Mr. Cohen.
The only thing that we in the school administration have ever worried about in regard to Sam is the prospect of funding his bottled water. Sam is such a passionate and prolific speaker that he needs a steady supply to maintain his voice. So far we have gotten a pass on this, as students have bought it for him, including what must have been a year’s supply on his last birthday.
It will be a sad day when we announce that Sam will be pursuing his graduate degree on a fulltime basis. We can only hope that he keeps his promise and returns to us as soon as the ink is dry on his new diploma.
Sincerely,
Harold W. Brown
Principal
George Mason High School

申请香港读研首先要完善资料、然后预约香港院并等待香港学校的面试通知 ，最后是等待录取通知书。具体内容如下：

一、完善资料：

首先开始着手准备你的个人资料，准备文书、自述、推荐信等，不断完善丰富你的资料。同时与老师进行沟通，看自己适合哪方面的发展，有哪些潜力可以挖掘，力求让自己的文书优秀。其中推荐信，必须是学术领域中的人，其他人则不被接受。推荐信是一、两份表格，而不是洋洋洒洒的一大篇，其内容是对你学术才能的评价。此外还要求对你的研究计划做出评价和建议，这一点也不应忽视。

二、香港院校预约：

在学校领取成绩单，推荐信找相应的人员签字盖章。翻译成绩单，并拿英文版的成绩单找学校盖章，时时关注目标院校报名时间，进行预约申请。一般来说，只要发一个电子邮件给招生办公室或者系里，对方便会寄来有关表格。不过与美国不同的是，香港的大学会要求你说明自己的研究意向，当然只要一个很宽泛的范围即可，无须非常具体。材料一般是免费的，如果觉得麻烦，甚至可以从网上下载。

三、等待香港学校的面试通知：

当你的准备材料都递交目标院校后，接下来就可以等待面试通知了。在没有接到面试通知时也要积极准备，多次对着镜子演练，看有什么地方做的不足，自己表达力求完美。面试通知的形式一般为E-mail告知、电话告知或在线系统上告知。所以在申请后要勤于查收邮件和查看申请系统。面试的方式各校甚至各学院都不相同，有Skype、电话面试，还有些专业如港大的经济学，会统一组织入选的学生在国内某大城市统一组织面试和笔试。

四、等待录取通知书：

面试表现良好，那么恭喜你，你即将成为一名港校的研究生了。接下来就是寻找同行朋友或者校友、定机票、了解衣食住行生活指南、海外生活环境等等。

补充材料：

香港读研申请要求：

一、本科背景：

如果你大学就读于大陆“211”或者“985”，申请的成功率自然就大了。这点在商科专业上特别明显。如目前火热的“经济学”专业，尤其注重本科背景。如果你是双非一本，甚至二本三本，也不要灰心，还有以下方法可以补救。

二、大学平均绩点：

平均绩点通常指平均学分绩点（即GPA，Grade Point Average）。有意愿申请香港研究生的同学，一个好的GPA是一切的前提保障。大部分港校都要求你的绩点在3.0以上（4分制）也就是80分以上。如果你的专业考试科目较难，绩点相对较低，可以注明在专业排名。如3.1专业前10%。总之，高绩点，说明你的学习能力较强，也更在竞争激烈的港校脱颖而出。

三、语言成绩：

语言成绩，主要指托福和雅思。但是部分学校也认可六级成绩。如香港中文大学、香港城市大学和香港理工大学。但也并非所有专业都可以接受。如香港城市大学的英语语言类专业就需要雅思7.0，但是不可接受六级。一般要求成绩TOEFL80以上，或IELTS6.0以上。若申请人希望通过语言成绩给考试加码的话，还是建议准备雅思或托福。香港的大学多是全英文授课，没有一个好的语言成绩势必在这方面吃亏，一个好的托福雅思成绩不仅可以增加你的申请成功率，还能让你听课更加轻松。

四、发表的学术论文：

学术论文是检验学生素质最好的手段，如果你在级别较高的期刊有过多篇的发表，那势必让你在众多申请者中脱颖而出。
