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

Step 7: complete the discourse according to the grammar rules.Cholera used to be one of the most 1.__________ (fear) diseases in the world. In the early 19th century, _2_________ an outbreak of cholera hit Europe, millions of people died. But neither its cause, 3__________ its cure was understood. A British doctor, John Snow, wanted to solve the problem and he knew that cholera would not be controlled _4_________ its cause was found. In general, there were two contradictory theories 5 __________ explained how cholera spread. The first suggested that bad air caused the disease. The second was that cholera was caused by an _6_________(infect) from germs in food or water. John Snow thought that the second theory was correct but he needed proof. So when another outbreak of cholera hit London in 1854, he began to investigate. Later, with all the evidence he _7_________ (gather), John Snow was able to announce that the pump water carried cholera germs. Therefore, he had the handle of the pump _8_________ (remove) so that it couldn't be used. Through his intervention,the disease was stopped in its tracks. What is more, John Snow found that some companies sold water from the River Thames that __9__________________ (pollute) by raw waste. The people who drank this water were much more likely _10_________ (get) cholera than those who drank pure or boiled water. Through John Snow's efforts, the _11_________ (threaten) of cholera around the world saw a substantial increase. Keys: 1.feared 2.when 3. nor 4.unless 5.that/which 6.infection 7.had gathered 8.removed 9.was polluted 10.to get 11. threat
Step 5: After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?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.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2. 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. He wanted to find the _3_____ of cholera in order to help people ___4_____ it. In 1854 when a cholera __5__ London, he began to gather information. He ___6__ on a map ___7___ all the dead people had lived and he found that many people who had ___8____ (drink) the dirty water from the __9____ died. So he decided that the polluted water ___10____ cholera. He suggested that the ___11__ of all water supplies should be _12______ and new methods of dealing with ____13___ water be found. Finally, “King Cholera” was __14_____.Keys: 1. doctor 2. 19th 3.cause 4.infected with 5.hit 6.marked 7.where 8.drunk 9.pump 10.carried 11.source 12.examined 13.polluted 14.defeatedHomework: Retell the text after class and preview its language points
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.

You have no excuse for not going.你没有理由不去。He was punished for not having finished his homework.他因未完成作业而受到惩罚。2.动词ing形式复合结构由物主代词或人称代词宾格、名词所有格或普通格加动词ing,即“sb./sb.'s+doing”构成。动词ing形式的复合结构实际上是给动词ing形式加了一个逻辑主语。动词ing形式的复合结构有四种形式:①形容词性物主代词+动词ing②名词所有格+动词ing③代词宾格+动词ing④名词+动词ingHer coming to help encouraged all of us.她来帮忙鼓舞了我们所有人。The baby was made awake by the door suddenly shutting.这个婴儿被突然的关门声吵醒了。Can you imagine him/Jack cooking at home?你能想象他/杰克在家做饭的样子吗?无生命名词无论是作主语还是作宾语都不能用第②种形式。Tom's winning first prize last year impressed me a lot.汤姆去年得了一等奖使我印象深刻。Do you mind my/me/Jack's/Jack leaving now?你介意我/杰克现在离开吗?Excuse me for my not coming on time.很抱歉我没能按时来。His father's being ill made him worried.他父亲病了,他很担心。We are looking forward to the singer's/the singer to give us a concert.我们盼望着这位歌手来给我们举办一场演唱会。
问题1. 用一个大写的英文字母或一个阿拉伯数字给教室里的一个座位编号,总共能编出多少种不同的号码?因为英文字母共有26个,阿拉伯数字共有10个,所以总共可以编出26+10=36种不同的号码.问题2.你能说说这个问题的特征吗?上述计数过程的基本环节是:(1)确定分类标准,根据问题条件分为字母号码和数字号码两类;(2)分别计算各类号码的个数;(3)各类号码的个数相加,得出所有号码的个数.你能举出一些生活中类似的例子吗?一般地,有如下分类加法计数原理:完成一件事,有两类办法. 在第1类办法中有m种不同的方法,在第2类方法中有n种不同的方法,则完成这件事共有:N= m+n种不同的方法.二、典例解析例1.在填写高考志愿时,一名高中毕业生了解到,A,B两所大学各有一些自己感兴趣的强项专业,如表,
当A,C颜色相同时,先染P有4种方法,再染A,C有3种方法,然后染B有2种方法,最后染D也有2种方法.根据分步乘法计数原理知,共有4×3×2×2=48(种)方法;当A,C颜色不相同时,先染P有4种方法,再染A有3种方法,然后染C有2种方法,最后染B,D都有1种方法.根据分步乘法计数原理知,共有4×3×2×1×1=24(种)方法.综上,共有48+24=72(种)方法.故选B.答案:B5.某艺术小组有9人,每人至少会钢琴和小号中的一种乐器,其中7人会钢琴,3人会小号,从中选出会钢琴与会小号的各1人,有多少种不同的选法?解:由题意可知,在艺术小组9人中,有且仅有1人既会钢琴又会小号(把该人记为甲),只会钢琴的有6人,只会小号的有2人.把从中选出会钢琴与会小号各1人的方法分为两类.第1类,甲入选,另1人只需从其他8人中任选1人,故这类选法共8种;第2类,甲不入选,则会钢琴的只能从6个只会钢琴的人中选出,有6种不同的选法,会小号的也只能从只会小号的2人中选出,有2种不同的选法,所以这类选法共有6×2=12(种).因此共有8+12=20(种)不同的选法.
1、认真研究教材。吃透教材是教师进行有效课堂教学的立足点。除了教学的重点,难点的把握,教师还应该考虑到教材的重组与延伸。 2、仔细推敲教学方法。随着网络的的普及,教师可以利用的资源是越来越多了,教师交流教学方法的渠道也是越来越广,我们可以发现相同的教学内容往往有多种不同的教学方法,如何选择适合自己班级学生的教学方式在教学中有着举足轻重的地位。 3、有针对性的设计课堂练习。学生吸收知识第一印象往往十分重要,而教师在课堂上设计的听说读写各式练习情况往往往直接影响着学生课后练习的正确率。
我一直都喜欢阅读课外书籍,每天都会利用时间来阅读,比如放学后,比如在假期内都是我阅读的时间,课外阅读能够增加知识,更能够让我们学到更多的东西。 因为我经常阅读课外书籍,我在写作文时,能够轻易的运用好每个文字,同时也能够看到更多不同的文化,习俗,学习很多人生哲理,让我得到了极大的成长。从阅读中找到更加有趣的知识,丰富自己的知识储备,对我们来说这是成长,更是一次体验,课外阅读的好处不光是这些,更能够提升我们的阅读理解能力。

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……
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。
尊敬的老师们,同学们:Dearteachersandclassmats,大家早上好!我是二(1)班的张xx。今天我演讲的主题是《学会自我保护,安全与我同行》。Goodmorning!Iam______fromclass1Grade2.mytopicis“Tolearnhowtoprotectmyself,tobesafeeverytime”.校园是我们共同学习的地方,这里有老师,有同学,在这个大家庭里,我们快乐地学习,健康地成长。但是,在这个大家庭里,也很容易发生意外。campusisaplacewestudytogether.Thereareteachersandstudentshere,westudyhappilyandgrowhealthily.However,wemeetaccidentsometimes,too.午觉过后,有同学奔跑着回到教室;课间十分,有同学在教室走廊里追逐打闹……像这样不看路,快速奔跑都是非常危险的,严重的还会骨折。我曾经看到一位高年级的大哥哥,下课铃一响,他就飞快地从教室冲出来,快到直饮水机旁边时,因为跑得太快,他没看到脚下有东西,摔倒在地上,送到医院一看,已经骨折了,好多天都没来上学,不光耽误了功课,还受了许多罪。
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。
