第十一周国旗下讲话稿：学习是一种责任
尊敬的各位领导、老师，亲爱的同学们：大家早上好！我是一年三班的xx。在开始今天的国旗下讲话之前，我先给大家诵读一段《三字经》，“犬守夜，鸡司晨。苟不学，曷为人。蚕吐丝，蜂酿蜜。人不学，不如物”。你们知道这段话的意思吗？这段话的意思是：狗知道在夜间替人守卫门户，公鸡知道每天早晨鸣叫报晓。人如果不知道用心学习，还有什么资格称为人呢？蚕吐丝可以供人们做衣服，蜜蜂酿蜜可以供人们食用。人要是不学习，那连动物都不如了。雄鸡报晓，蜜蜂酿蜜，春雨润万物，瑞雪兆丰年，世间万物都有自己的责任。同学们，作为学生，我们的责任是什么呢？对，是学习，所以今天我国旗下讲话的题目就是“学习是一种责任”。自古以来就有“补漏趁天晴，读书趁少年”、“花有重开日，人无再少年”的古训，由此可见学习的重要性。同学们，既然我们走进了学校的大门，就必须担当起自己的学习责任。那么，你承担起这份责任了吗?上课你认真听讲了吗？课后你认真、及时完成作业了吗？遇到难题你不逃避而是认真思考或请教他人吗？

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!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3. Inspire the students to systematize the function and usage of noun clause1.Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.2.Inspire the students to systematize the function and usage of noun clauseStep1: The teacher ask studetns to find out more nominal clauses from the reading passage and udnerline the nominal clauses.

二、孟子的仁政思想1．民本思想。孟子说：“民为贵，社稷次之，君为轻。是故得乎丘民而为天子，得乎天子为诸侯，得乎诸侯为大夫。”（《孟子·尽心下》）得到百姓拥护的人才能成为天子，得到天子欢心的人可以成为诸侯，得到诸侯欢心的人可以成为大夫，可见“民为贵”的道理。孟子在尖锐复杂的阶级斗争中看到人民的力量，认为社会安定的前提在于百姓的安居乐业，这一点在当时也是有积极意义的。2．邦国的主权在民。孟子与梁惠王谈话，梁惠王问：“天下恶乎定？”孟子回答：“定于一。”梁惠王问：“孰能一之？”孟子回答：“不嗜杀人者能一之。”梁惠王问：“孰能与之？”孟子回答：“天下莫不与也。”（《孟子·梁惠王上》）意思是说，如果一个君王不嗜杀戮，那么，天下没有不愿意把政权交给这个君王的人。万章问孟子：“尧以天下与舜，有诸？”孟子说：“否；天子不能以天下与人。”万章问：“然则舜有天下也，孰与之？”孟子说：“天与之。”

2．避免使用过多的描写手法，避免过多地使用形容词，特别是华丽的辞藻，尽量采用直截了当的叙述和生动鲜明的对话，因此，句子简短，语汇准确生动。在塑造桑地亚哥这一形象时，他的笔力主要集中在真实而生动地再现老人与鲨鱼搏斗的场景上。鲨鱼的来势凶猛，老人的沉着迎战，机敏矫捷，都写得生动逼真。如写鲨鱼出现的情形，“当一大股暗黑色的血沉在一英里深的海里然后又散开的时候，它就从下面水深的地方窜上来。它游得那么快，什么也不放在眼里，一冲出蓝色的水面就涌现在太阳光下。”这段描写没有一个比喻句和形容词，但鲨鱼的凶猛、快捷，形势的紧迫却立刻展示在读者面前，清新洗练的叙述文字和反复锤炼的日常用语，使人读来有身临其境之感。文中对大海的描写粗犷简洁，犹如一幅水墨山水画，读来令人心旷神怡，美不胜收。
