杨昉：20年前毕业于华师一，20年后清华大学博导 / 四六文摘

2021年6月23日，清华大学校友师生团队莅临华师一，在二号报告厅举办了一场专题宣讲活动，活动的主题是“'清清华一’大学认知活动”。我校2019级高二年级长飞班班主任陈春媚老师、长储班班主任阮荣祥老师带领全班学生全程参与了此次活动。本场专题宣讲活动旨在“萃精英、开视野、疑解惑、壮雄心、展鸿鹄”。

宣讲活动由线上和线下两部分组成。线下活动中，清华大学自动化学院（研一）的李舒燕学长、材料学院（大三）的王惊涛学长带领长飞、长储班学生“云旅游”，领略了清华大学深厚的历史底蕴、丰富的校园文化、多彩的学习生活、雄厚的师资力量、多元的学术方向和卓越的学术成就，台下认真聆听的同学们神情专注，心驰神往。

来自清华大学数学系的余成龙老师还为同学们带来了一场别开生面的“数学微课堂”，余老师以欧拉公式引入，通过解析多面体的定点数、棱数和面数之间的隐藏关系，带领同学们研究了拓扑学、物理学等学科中的几个奇妙的计数问题，点燃了同学们钻研数学的热情，也让同学们提前感受到了清华大学自由活泼的教学方式。

2001年毕业于华师一附中的学长杨昉，现任教于清华大学电子工程系。杨老师首先深情回顾了当年在华师一学习、生活、奋斗的美好生活，然后以北斗系统为例，用详尽的数据和深入浅出的讲解，为同学们介绍了清华电子工程系无线光通信领域的最新研究成果及方向。台下的同学们沉浸其中，纷纷惊叹科技的魅力。

线上活动中，清华大学机械工程实验班的孙成恺学长、基科班郭瑞程学长，分享了他们在清华度过的四年大学时光，讲述了作为清华人美好而难忘的回忆。

最后的交流互动环节掀起了活动的新高潮，高二年级长飞班、长储班的同学们踊跃发问，就当下学习生活中的诸多疑惑，向清华师生们求教。例如：在考试频繁、试题海量的高三学习中，如何平衡完成作业与整理知识框架的关系？填报大学志愿时，是兴趣优先还是专业优先？进入清华是否允许理转文？专程回馈母校的清华师生团，对同学们提出的这些问题，知无不言，言无不尽，或联系自身经历事例，或列举身边同学、舍友事例将他们优秀的方法、深刻的感悟、成功的经验倾囊相授，令台下仔细聆听的“长班”同学们受益颇多。

举办本次活动的清华大学校友师生团队，感恩华一，回馈母校，情真意切；参加活动的2019级高二“长班”学子，高山仰止，心有所向，立志奋发。活动结束后，许多“心中有梦、眼里有光”的同学依然围着清华师生团，继续一对一的热烈交流。他们纷纷表示“从清华学长挺直的脊背中，我看见了未来我的模样。”相信深受此次活动激励的2019级高二“长班”同学们，定会以华师一优秀学长们为榜样，树立远大目标，怀鸿鹄之志，扬理想之帆，以更加昂扬的姿态，迎接未来新的挑战！
