关于11月27日感恩节的国旗下的讲话
学会感恩亲爱的老师们、同学们:大家好！今天我讲话的题目是《学会感恩》。“感恩”是中华民族的传统美德，“滴水之恩，涌泉相报”“谁言寸草心，报得三春晖”，这是祖先为我们留下的教诲。怀着一颗感恩的心看世界，你才会真正幸福。父母的每一句关心的话语,你是否想到说一声“谢谢”，为了你的安全，为了你的温饱，为了你的成长，他付出的不仅是汗水，更多的是心血，对此，你是否有一颗感恩的心？每当你走进校园时，你会看见高大的树林，美丽的花草，整洁的教室，此时此刻的你是否想到这舒适的学习环境是学校、老师、同学们共同营造的？当我们能够这样幸福的在这样的环境中学习、生活，对此，你是否有一颗感恩的心？同学们，如果你心存感恩，当你因犯错误而受到老师的批评时，你应该虚心接受，因为你知道，老师是真心帮助你；当你每天都听到父母的唠叨时，你应该耐心倾听，因为父母是很爱你的。
关于安全每一天的国旗下的讲话
国旗下的讲话稿安全每一天各位老师、同学们：大家早上好！“安全”这个词对大家并不陌生，像“安全重于泰山”这样的警示更是时常见到。虽然安全十分重要，但在日常生活中有些人却总把安全抛在脑后，其实当他们把安全轻视的时候，危险就在慢慢向他们靠近。远的不说，回想一下在本学期，还记得我们邀请交警叔叔给大家做的安全讲座吧？那些就发生在我们周边的一个个交通事故的片段，你还印象深刻吗？是啊，当你看到一个个鲜活的生命消失于车轮之下，当你发现一阵阵欢声笑语湮没在尖锐的汽笛声中，当你面对那些触目惊心的场景时，能不感到震痛吗？

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!

Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease.

No. The map helped John Snow organize his ideas. He was able to identify those households that had had many deaths and check their water-drinking habits. He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.

个人红与黑读书心得精品例文
在社会现实阻碍实现抱负时只有两种选择：退避或是反抗。那些当着小职员不求上进、整天抱怨生活乏味的青年就是退避者，他们或许平庸得舒适却被社会的前进所淘汰。能不断树立人生目标、决定实现人生理想的便是和于连有同样气概的反抗者。这个时代当然不欢迎虚伪的言行作为手段，但仍然需要对生活的热情来反抗空虚的度日。这样，于连悲剧性的结局除了昭示“个人反抗行不通”外，就有了对当今社会更实际的意义。
