国际志愿者日国旗下讲话：做一名红领巾志愿者
尊敬的老师、亲爱的同学们：大家上午好！想问大家一个问题：你们知道什么是志愿者吗？志愿者就是不为任何物质报酬，主动承担社会责任并且奉献个人的时间及精神的人。在我们邗实的校园里就有一群红领巾志愿者，清晨，他们用灿烂的笑容迎接同学们返校，引导老师摆放车辆；课间，他们热心地提醒同学不大声喧哗、不追逐打闹；餐厅里，他们耐心地教同学们如何摆放餐具……在服务他人的时候，他们自身的文明素养得到了提升，同时，也收获着精神上的愉悦与满足。老师还想问大家第二个问题：你们想做一名红领巾志愿者吗？做一名红领巾志愿者其实并不难。校园里，你可以积极参加各项服务：餐厅、教室、包干区检查，楼层值日，中队值日你可以努力争取岗位。随手捡起地上的垃圾、关掉滴水的龙头，用自己的微薄之力去帮助他人，也是一种志愿服务。
第31个国际志愿者日国旗下讲话稿：志愿者在行动
敬爱的老师，亲爱的同学们：大家早上好！今天我演讲的题目是《志愿者在行动》。同学们，你们可知道，今天，我们迎来了第31个国际志愿者日。那么，志愿者是些什么人呢？大家知道著名的白求恩大夫吗？抗战期间，白求恩大夫不远万里，从加拿大来到中国，一到延安，他就奔赴战斗最前线，为八路军救护伤员，并将生命留在了中国。他就是一位典型的国际志愿者。其实，志愿者离我们并不遥远，在我们的身边，也有着许许多多平凡的志愿者。同学们有没有发现，每天上学放学，家长志愿者们总是早早地来到学校，在学校周边辛苦地守护着我们的平安。再看校内，那些值日的同学坚守在自己的岗位上，一丝不苟、认真负责地监督着每一位同学。在马路上，人们经常能见到拿着红旗，吹着口哨指挥交通的劝导员，每逢节假日，敬老院里总会有一些叔叔阿姨们带着礼品前来慰问老人······

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:?

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!
