严格防控疫情。一是严防疫情反弹外溢。我们对XX镇封控区、管控区及重点暴露场所进行严格管理,连续开展“扫楼敲门”行动,确保相关人员“足不出户”“足不出小区”,防止疫情在社区出现反弹。全市倡导非必要不离XX、非必要不出省。二是严防疫情倒灌。这是为了应对当前全国疫情发展出现的形势变化,我们正在加大力度推进的重要工作。重点是像排查出此次XX疫情首两例病例一样,迅速管控排查出涉疫地区来XX返XX人员,以免新的疫情发生。请广大市民朋友密切留意疫情发展动态,如非必要近期不要前往中高风险地区以及疫情发生地区;
一、总体情况:全市疫情总体平稳可控。 12月26日0—24时,我市XX镇新增X例新冠肺炎确诊病例,在集中管理的密切接触者中检测发现。确诊病例XX,XX月XX日作为密切接触者被纳入集中管理,XX月XX日-XX日连续核酸检测阴性,XX月XX日晚核酸检测初筛阳性,XX月XX日复核结果阳性,已转运至定点收治医院隔离治疗,经诊断,为新冠肺炎确诊病例(轻型)。 12月13日至12月26日24时,我市累计报告新冠肺炎确诊病例XX例,均为轻型或普通型,全部都在XX镇,没有发生外溢。由于密切接触者等重点人群尚在医学观察期内,不排除还有续发病例的可能,昨天新增这X例也符合这一预判。目前,全市疫情总体平稳可控。
伴随着国旗冉冉升起,我们伟大的祖国在祥和庄重的氛围中度过了63周岁的华诞。在举国欢度国庆节的前夕,在刚刚过去的9月25日21时10分04秒,神州七号载人飞船带着翟志刚、刘伯明、景海鹏三位宇航员一飞冲天,带着中华民族克服冰雪灾害以及汶川地震的百折不挠的精神、带着成功举办奥运会、残奥会的顽强拼搏精神,骄傲地向太空宣誓:太空漫步,我们中国人来了!当五星红旗在太空、在翟志刚的手上傲然挥舞时,我们已经成功地成为世界上实现太空行走的第三个国家。身处伟大的祖国,我想每一个中国人、包括全校师生心底的那种豪迈无法用语言来形容。今天,我们度过国庆七天长假重新回到校园,我们同样要勾勒出我们自己的成功路径。1276名08级同学通过9月份的试读考查,即将陆续取得xx市xx商业学校的学籍;1193名07级同学正式进入主攻专业技能的第二学年;06级高考班45同学进入了冲刺的第三年,他们在新学期动员大会说有信心“用勇气刷新成绩”
今天我演讲的题目是《践行文明,创建和谐、文明校园》。我国是一个有着几千年历史的文明古国,素以“礼仪之邦”著称。然而在岁月的长河中,我们的祖国历经磨难,又涅盘新生,可以说如今大家是腰包“鼓起来”,生活“阔起来”,远离了物质的窘迫,却又浑然不觉地陷入“发展的列车匆匆驶过精神站台,现实的变化把心灵的地图抛在身外”的另一种窘境中。恩格斯说:“国家是文明社会的概括。”作为社会主义核心价值观的关键词汇,“文明”折射着一个国家发展的境界。学校是传播文明的摇篮,是生长礼仪的沃土,是成就“礼仪之邦”的起点。那么,我们中学生又当如何去践行文明呢?我认为,第一、要语言文明。古语云:“诚于中而形于外”,文明礼貌是一个美好心灵的自然表露,语言文明是一个人整体形象的重要组成部分。语言文明,就是要让“请、你好、不好意思、谢谢、打扰了”成为自己的日常用语,就是要杜绝脏话,我们身边,还有一些同学出口成脏,对别人的心理造成了伤害,这就是不文明。在现实生活中,我们常会碰到这类情况:一句诚实、有礼貌的语言,可止息一场不愉快的争吵;一句粗野污秽的话,可导致一场轩然大波。
各位老师、同学们、大家上午好!今天我讲话的题目是“反对校园欺凌,共建和谐校园”。讲三个方面:1.什么是校园欺凌。所谓“校园欺凌”就是以大欺小,以多欺少,以强凌弱,像这样的事例在校园内曾经出现过,如向低年级学生索取钱物,不给就打,两个同学发生小矛盾,找高年级学生帮忙等等。一旦发生这样的事情,它不但会伤害孩子的身体,还会使一颗纯净的心灵蒙上阴影,严重时,还会威胁人生安全。2.为什么要治理校园欺凌。因为欺凌现象在有的地方时有发生,已经严重影响了孩子的身心健康,给社会带来恶劣影响,违背了中华几千年来的传统美德——友善,而且和社会主义核心价值观是背道而驰的,国家教育部非常重视孩子的健康成长,专门出台文件专项治理校园欺凌,严厉打击校园欺凌现象。3.作为学生的我们,如何做好防范呢?首先,要学会宽容。宽容就是人与人之间相处时能充分的理解他人、体谅他人,拥有宽阔的胸怀。同学们生活在一起是一张缘分,万一产生一点摩擦是正常的。要学会说:“对不起”。
4月19日,湖北红安00后为争女朋友斗殴,操板砖砸人手段凶残。 4月30日,福建南安一初一男生被同校学生及社会青年追打,捅伤。 5月12日,福建晋江学生校外打架一死两伤。 5月19日,辽宁沈阳宁官实验学校篮球暴力事件。 6月16日,山东济南一中学多名学生暴力殴打同校学生。 6月21日,湖南怀化一女生在校园遭8名学姐群殴致耳膜穿孔。 6月26日,河南信阳数百中学生赤膊群殴。(二)抵制校园暴力此环节设置三个问题,这三个问题分别是:1、同学间发生矛盾时,作为当事人,我们应该如何解决?2、矛盾一时难以解开,如何有效扼制校园暴力的发生?3、一旦发生校园暴力事件,如何应对?这三个问题,分别是从学生间出现矛盾时、校园暴力发生前、校园暴力发生中三个不同阶段提出的,能够让学生思考在不同情况下如何处理矛盾,并尽可能的避免校园暴力的发生,一旦发生校园暴力,也能够及时采取措施避免伤害。最后师生共同总结出避免校园暴力的做法: 从受害者的角度想:不理睬;找老师;懂自救。 从施暴者的角度想:想后果;勿冲动;换位思考。
一、找准症结,认真分析全州应急管理工作重点突出薄弱环节机构改革后组建的应急管理局,整合了州安监局职责、州政府应急办职责、州公安局的消防管理职责、州民政局的救灾职责,以及州国土局的地质灾害防治、州科技局的防震减灾职责、州水务局的水旱灾害防治、州农委的草原防火、州林业局的森林防火等相关应急救灾职责,同时承担州安全生产、防汛抗旱、减灾、森林防火等指挥部(委员会)的职责。在成立之初,在诸多方面都存在明显不足。(一)安全生产风险防范手段单一。由于缺乏专业装备技术支撑,全州大量煤矿、危险化学品、烟花爆竹、非煤矿山、尾矿库、冶金工贸等高危行业安全监管基本上以“人海战术”模式为主,企业重要风险点管控情况、运行状况长期处于监管视线范围之外。

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!

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.

If a traffic accident happens and someone is injured, the following steps can be used to treat the injured.In the first place, we should make sure that the accident scene is safe so that we won’t get hurt. We should ask the injured person if he is OK, and see if he is breathing. What’s more, we should check for cuts and wounds. If he is bleeding badly, it is vital that we should try to stop the bleeding by applying pressure to the injury. This is because if a person loses too much blood, he may die. If necessary, take the injured person to the hospital as soon as possible.Do remember: when giving first aid, please be sure to place the person in a recovery position.
