自从去年家里装修完之后，我们在厨房装了一台电视，平时吃饭时会随便看看一些视频。大约两个月前的一天中午，我从学校接弟弟回家吃饭，无意间发现了一个叫 Alan Becker 的动画视频系列——“Animation vs.”，是 YouTube 上的一个非常有创意的系列。他最出名的作品之一就是《Animation vs Math》。
Alan Becker 的这些视频通常用一群小人（也有人叫他们“小黄人”、小橙色、火柴人）在电脑屏幕上互动的方式，讲述一个个富有创意、又带有教育意义的故事。虽然整个系列几乎没有一句对白，但却通过画面和动作把复杂的知识点讲得既直观又有趣。
我最喜欢的四个视频是《Animation vs Math》、《Animation vs Coding》、《Animation vs Physics》和《Animation vs Geometry》。每一集不仅让人捧腹大笑，还让人对背后的知识产生兴趣。比如在《Animation vs Math》中，小人们在坐标系、函数图像之间跳跃和作战，看得人不知不觉就理解了各种数学概念。而《Animation vs Coding》则展示了编程的魔法，小人甚至“黑进”了主人的电脑，自己写代码！《Animation vs Physics》里，小人们挑战了牛顿定律、重力和能量守恒，用夸张但合理的方式演绎了物理知识。
《Animation vs Geometry》则是另一个令人惊喜的作品。视频里，小人们与各种几何图形互动，有时被三角形包围，有时从正多边形中逃脱，有时又在空间几何中穿梭。通过他们的“冒险”，我对角度、面积、对称和旋转等概念有了更加立体的理解。这些原本在课堂上觉得枯燥的几何知识，突然变得生动起来。

Sorry to bother you but we have been assessing patient notes and it came to my attention that you used to have regular PSA blood tests although these seem to have stopped around 2017 & I can find no further mention of it. Is it something you are having done privately or is it no longer a concern anymore?
Over the past month, how often have you had a sensation of not emptying your bladder completely after you finish urinating?
Over the past month, how often have you had to urinate again less than two hours after you have finished urinating?
Over the past month, how often have you found you stopped and started again several times when you urinated?
Over the past month, how often have you found it difficult to postpone urination?
Over the last month, how often have you had a weak urinary stream?
Over the past month, how often have you had to push or strain to begin urination?
Over the past month how many times did you most typically get up each night to urinate from the time you went to bed until the time you got up in the morning?
If you were to spend the rest of your life with your urinary condition just the way it is now, how would you feel about that?

今年，我们让大娃再次报考 Perse，同时也报名了 Stephen Perse——这也是一所私立学校，考试时间正好安排在 Perse 考试的下一周。原本的计划是让他以 Stephen Perse 考试当作练手，结果却发现 Stephen Perse 的考试在 Perse 之后。
选择让孩子考 Stephen Perse，是因为感觉他可能考不上 Perse：太卷了。从考试难度上来看，孩子的反馈也印证了这一点：Perse 确实更难一些。
如果最终没能考上 Perse，我们打算让孩子去 Stephen Perse，算是“曲线救国”。因为 Perse 的部分名额会预留给剑桥几所私校的学生，比如 St John’s、Stephen Perse、King’s College School 等。这些私校的课程仅到 8 年级，并且会有针对性的私校升学准备，因此竞争非常激烈。
We really enjoyed meeting XXX at our recent entrance testing day. Through the assessment process, XXX performed impressively, demonstrating strong academic potential.
I am therefore very pleased to be able to offer him a place to start at Stephen Perse Cambridge Senior School in Year 9 in September 2025.
In addition, recognizing XXX’s excellent academic attainment across the assessments on our entrance testing day, I am delighted to award an Academic Scholarship to the value of a 50% discount of school fees for Years 9-11; please note that all students have the opportunity to apply for further scholarships at later points in their school careers. As an Academic Scholar, XXX will be expected to contribute to and promote the academic life of the School.
In terms of XXXX additional scholarship application, the Music department have asked me to pass on that they very much enjoyed meeting XXX at the assessment session, but, due to the very competitive field of applicants this year, were unable to make an offer of an award at this time. As with academic scholarships, all students have the opportunity in (re)apply for scholarships in co-curricular areas at later points in their school careers.
We very much hope that XXX will be really excited to accept our offer to join Stephen Perse Cambridge Senior School. We are committed to providing a challenging and stimulating academic environment in which all of our students can thrive and achieve their best, supported by exceptional pastoral care and a diverse range of engaging co-curricular opportunities.
I ask that you please confirm acceptance of the place at your earliest convenience, and no later than 4 March 2025, after which it may be offered to another family from our waiting list. If this time limit causes you any difficulties or if you have any questions please do not hesitate to contact our Admissions Office on 01223 454 762 or admissions@stephenperse.com. Please refer to the section below “Further Offer Information” for more details of the offer and how to confirm acceptance.
Many thanks for letting us know. We wish Eric every success and happiness at The Perse — I’m sure he will thrive there.
We send our very best wishes to you and your family for the years ahead.
