大学生在国旗下的讲话——无愧于胸前的校徽
同学们：我们每个人胸前都有一枚闪光的校徽，无论在什么地方，我们都有一种自豪感：我是一个东中人！校徽，虽然比不上漂亮的胸花，也比不上珍贵的奖章，但是，它代表着祖国和人民的重托，它代表着父母的期待，代表着老师的厚望，更代表着东中人的一份责任。校徽，见证着东中悠久的历史。从1925年起，东中穿越了80多年历史的风云，一步步发展壮大，从这里走出了一大批学贯中西的专家学者，更有一大批国家政治、外交、军事、经济、科技、文学、艺术、体育等方面的杰出人才，他们有的已为祖国的解放事业光荣献身，有的正在为祖国的现代化建设努力奋斗。在东中这片热土上，有老一辈革命家奋斗的足迹，有革命烈士流过的鲜血，也有几代东中人洒下的汗水。戴陶、吕土奇烈士为祖国的解放事业血洒疆场；粟裕将军、黄逸峰先生曾在这里点燃革命的火种。可以说东中校徽上印染着烈士的鲜血，东中校园是革命斗争的摇篮。校徽，记载着东中光荣的历史。近80年来，从这里走出了数以万计的栋梁之才，可谓桃李满天下，芳香遍四海。陈可吼、冒广根、吴秀永将军都曾在此求学；卞有生、周壁华院士曾在此就读；发明大王王卫东、运动健将严跃、郭建华也从这里走出……这一连串金星般的名字在玄“灿烂的．史姗上闪尤，念心成丧必每一步都包涵着老嫁谢心止，世刃展停的每一点成绩，都离不开东中这片沃土。校徽，也铭刻着东中今日的辉煌。

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分，只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

学习会计的心得体会
在还没有接触会计学这门课之前，我想许多人和我一样只有感性的认识，尽管它与我们的日常生活、工作和学习有密切的关系，甚至有些人已经同会计打过交道，或者已使用过会计凭证，或者阅读过会计报表。但问到我们会计是什么？我们也许会说：会计就是写写、算算。通过学习，我才发现会计并不是那么简单。 “管理活动论 ”者认为，会计是一项具有反映和控制职能的经济管理活动。而 “信息系统论 ”者则认为，会计是一个以提供财务信息为主的经济信息系统。从以上两个观点我们可以理解会计是一个数据处理，进而产生信息，利用这个信息达到加强经济管理，从而实现预期目标的工作或者活动。
