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!

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.

第十周国旗下讲话稿：学守纪讲规范，建设文明校园
尊敬的老师们，亲爱的同学们：大家上午好！今天我国旗下讲话的题目是《学守纪讲规范，建设文明校园》。同学们，当你们迎着朝阳踏进校园，一定希望展现在自己面前的是清洁的环境、明亮的教室；一定希望与自己相处的是文明守纪、团结友爱的同学；一定希望自己能在和谐文明的校园里健康、快乐地成长。赏心悦目的环境可以使人心旷神怡，和谐文明的校园能塑造美好的心灵。然而，在我们校园，还存在着一些不和谐的音符，每天同学们清扫干净后，总有些不自觉的同学把垃圾随手乱丢；课间有的同学大声喧哗吵闹，上下楼梯推搡拥挤……同学们，和谐、文明的校园需要我们每一个同学去创造，更需要我们用自己的一言一行来构建。当老师和同学们从你身边经过时，你点头微笑、致以问候；当你走进教室，轻轻推开关着的门；当地面有垃圾时，你弯腰拾起……
防灾减灾日国旗下讲话稿：增强防灾减灾意识，学会自我保护
林宇轩尊敬的老师、亲爱的同学们：大家好!今天我国旗下讲话的主题是“增强防灾减灾意识，学会自我保护”。今天是5月12日，也是我国的第8个防灾减灾日。今年的主题是：城镇化与减灾。在XX年3月2日，经国务院批准，把每年的5月12日定为全国的防灾减灾日。这既体现了国家对防灾减灾工作的高度重视，也是构建和谐社会的重要举措。通过设立“防灾减灾日”，定期举办全国性的防灾减灾宣传教育活动，有利于进一步唤起社会各界对防灾减灾工作的高度关注，增强全社会防灾减灾意识，普及推广全民防灾减灾知识和避灾自救技能，提高各级综合减灾能力，最大限度地减轻自然灾害的损失。虽然灾难看似离我们很遥远，但是如果没有树立起正确的安全防范意识，即使在我们的校园中，也会容易出现安全事故。举一个简单的例子，篮球可能是男同学们最喜爱的课余活动之一，然而就是在这一片不大的场地中，倘若轻视了自我保护，也会给自己带来惨痛的教训。很可能就在一次碰撞中，因为没有做好自我保护，就因此受到伤害，出现骨折等现象。因此，上体育课、体锻课前要做好准备活动，运动时注意不要剧烈碰撞，以免撞伤或摔伤；活动时，要在体育老师的正确指导下，使用体育器材或参加运动，课余时间活动要注意安全。

第九周国旗下讲话稿：增强安全意识，学会自我保护
同学们，老师们：大家早上好!今天我国旗下讲话的题目是《增强安全意识，学会自我保护》。同学们，安全无小事，事事须小心。增强安全意识，学会自我保护，是杜绝安全事故发生的最好法宝。然而，我们许多同学思想上、心理上和行为上都忽视了安全工作的重要性。据中国青少年研究中心的全国性大型调查发现，安全事故已经成为14岁以下少年儿童的第一死因，并有逐年增加的趋势;全国每年约有1.6万名中小学生非正常死亡，平均每天有40多人，就是说几乎每天有一个班的学生从我们这个世界“消失”!一个个触目惊心、血泪交织的悲剧叫人扼腕叹息、心有余悸，更对我们敲响了安全的警钟。安全关系着我们的生命与健康，切不可麻痹大意。因此，我们一定要增强安全防范意识，提高自我保护能力。首先，要充分认识安全的重要性，树立高度的安全意识。在对待安全问题的态度上，有一种思想特别要不得!那就是认为提高安全意识，实施安全行为，是胆小怕事;而胆大妄为，敢于冒险是勇敢!这种思想是完全错误的!存在这种思想的人往往好出风头，不听教导，也最容易发生安全事故。比如，在公路上飞车的大多会发生交通事故，手持鞭炮燃放的大多会被炸伤，喜欢追逐打闹的大多会发生碰撞事故，喜欢舞刀弄枪的往往会造成伤害……

法律手段：制定和运用经济法规，包括经济立法、经济司法活动等行政手段：采取强制性的行政命令、指示、规定等运用举例：我国一些地区遭遇突如其来的“禽流感”，禽类养殖户损失惨重。国家采取了对疫区封锁，对疫区的养殖户进行经济补贴，以及国家出资统一对疫区进行消毒等措施进行防治，并规定任何人不得将家禽带出疫区，违者追究法律责任。请结合材料说明在防治“禽流感”、发展禽类养殖的过程中，我国政府分别采取了哪些措施教师分析：对疫区养殖户进行经济补贴体现经济手段；对违反规定者追究法律责任，体现法律手段；对疫区进行封锁体现行政手段。（四）反思总结，当堂检测。教师组织学生反思本节课的主要内容（参照板书），进行总结。设计意图：对本节课的内容进行小结，学生的概括过程也是检验学生对本节课理解程度的过程。再次明确学生是学习的主体，并能够发现，问题解决问题。
