【正确答案】[范文]
   Dear Professor Li,
   I'm writing to you for applying for financial aid to a research project. As we know, Innovation and Creativity Fund is to be granted to extracurricular scientific activity and invention in our school.  Students who got financial aid have made remarkable achievements in various scientific projects.
   We, three first-year students, are working as a team to develop a model plane. We are going to participate in the 13th "Challenge Cup" of National Undergraduate's Extracurricular Scientific and Technological works competition. We attach a draft of the plane we are designing to this letter, and the plane is powered by a new kind of environment-friendly fuel. Now the research is in need of financial assistance, so we are writing this letter in the hope that the school could offer financial support to our research proposal.
   We promise that we will make wise use of the money we receive. The money will be spent on items such as equipment, consumable supplies and related books. What's more, we'll provide the advisory committee of the fund with monthly progress reports, financial reports and receipts of expenditures.
   Please take our request into consideration and take a look at our attached draft. Thank you for your time and attention.

尊敬的李教授：
   我写这封信是想申请一个研究项目的经济资助。众所周知，创新基金是学校授予给课外科学活动和发明的。获得经济资助的学生们在各种科研项目中都获得了了不起的成就。
   我们团队的三个成员都是大一学生，致力于开发一个模型飞机，准备参加第13届“挑战杯”全国大学生课外科技作品竞赛。随信附上我们正在设计的模型飞机的草图，这个模型飞机是由一种新型环境友好型燃料提供动力的。当前这个研究正需要经济援助，所以我们写信给你，希望学校能给我们的研究计划给予经济援助。
   我们保证会合理利用收到的援助金。这些资金会用于如设备，消耗品及相关书籍的购买上。此外，我们会每月给基金的咨询委员提供一份进度报告、财务报告以及花费的收据。
   请考虑一下我们的请求，看看随信附带的草图。谢谢你花费时间和精力在此事上。
