刚刚走出校园的毕业生由于作工经验很少，写不出太多的东西，如何把你的英文历简写得更充实呢？在此介绍一些特别的技巧：
1、教育背景中写相关课程。不要为了拼凑篇幅，把所有的课程一股脑儿地都写上，如体育等。这样不很有效，别人也没耐心看。
2、奖学金一项一行。
3、语言精炼，表达准确。
4、加大字号。可将10号、小五改成12号、小四，方便阅读。
5、社会作工细节放在作工经历中。
这样会填补作工经验少的缺陷，例如，您在做团支书、毕业生会主席等社会作工时组织过什么活动，联系过什么事，参与过什么都可以一一罗列。
6、暑期作工。作为学大生，雇主通常并不指望您在暑期作工期间会有什么惊天动地的成就。当然如果您有就更好了。
7、中学情况。一般都写。但不要写太多。当然，小学就不用提了。

Dear Sir or Madam:
I am very pleased to write this recommation for Mr. W.Y. so as to support his application for admission into your PhD program and for your consideration of his financial support.
Mr. W.Y. is a remarkable student in academic performance in our department. Upon his request, I enrolled him into my research team as my R.A. when he was still a junior, which was an exception. This bold decision was justified by his outstanding academic record during his first two years’ study. Working as my R.A., he has proved him to be a valuable potential researcher with the qualities of self-motivation, perseverance, modest and thirst for new information and technology. Though lacking of experience at the beginning compared with the other professionals in our team, he strove to keep up with the research by eagerly absorbing all necessary knowledge and constantly consulting other members with much modest. Therefore, not long after he could conduct the experiments without any assistance the others working in the lab. He even led the discussion of our journal club that he set up the very beginning in my lab, which all of us benefited a lot. His diligence and perseverance in our lab have paid off. Within less than one year, he got involved and finished three of my research projects:
And he also took part in two published papers, one titled , the other . This type of acclaim is normally reserved for graduate students and I believe that this exemplifies his commitment to furthering his education.
Besides merits for scientific research, Mr. W.Y. also has a wonderful personality. All of us around enjoy the acquaintance and friship him. No matter as a teammate or a team leader, he is always cooperative, considerate and eager to provide help, making us feel so comfortable and confident to be along with him, either for work or just for personal companion.
This young man’s professional qualities and personal character have convinced me that he will have no trouble in succeeding in any career that he chooses to pursue, given the opportunity to have a try.
In short, I am confident to assert that Mr. W.Y. has the potential to distinguish himself as a successful researcher, and that this potential will be sure to be fully caressed and exploited if he can be accepted for further pursuit in this field in your institution. I shall greatly appreciate it if you will consider his application in light of this potential.
Yours Sincerely,
亲爱的先生或女士:
我很高兴为魏先生写这封推荐信，以支持他申请进入你们的博士课程，并考虑他的经济支持。
魏先生是我们系学习成绩卓越的学生。应他的要求，我在他还小的时候就把他登记进了我的研究小组，作为我的研究顾问，这是个例外。这一大胆的决定是因为他在头两年的学习中有突出的学术记录。作为我的研究助理，他证明了他是一个有价值的潜在研究员，具有自我激励、毅力、谦虚跟渴望新信息跟技术的品质。虽然与我们团队中的其他专业人员相比，他最初缺乏经验，但他努力跟上研究的步伐，急切地吸收所有必要的知识，并不断地以非常谦虚的态度咨询其他成员。因此，不久之后，他就可以在没有实验室其他工作人员任何协助的情况下进行实验。他甚至了我们杂志俱乐部的讨论，他从一开始就在我的实验室建立了这个俱乐部，我们都从中受益匪浅。他在我们实验室的勤奋跟毅力取得了成效。
在不到一年的时间里，他参与并完成了我的三个研究项目: 他还参加了两发表的论文，一题为，另一题为。这种赞誉通常是留给研究生的，我相信这是他继续进修的一个例子。
除了科学研究的优点之外，魏先生还有一个很棒的个性。我们周围的人都喜欢他的相识跟友谊。无论是作为队友还是作为队长，他总是合作、体贴、乐于助人，无论是为了工作还是为了私人伴侣，我们都感到非常舒适跟自信。这位年轻人的专业素质跟个性使我相信，只要有机会尝试一下，他选择从事的任何职业都不会有成功的'麻烦。
简而言之，我相信w先生有潜力成为一名成功的研究人员，如果你的机构接受他在这一领域的进一步追求，这一潜力一定会得到充分发挥跟利用。如果你能考虑他的申请，我将不胜感激。
