    1. 这个寓言是一个关于一位国王古寓言。 The fable is an old fable about a king.2.作者用这个故事让读者对于社区的问题负有个人责任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 这个故事十分成功的实现了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3. Does the writer give his or her opinion about the character or their actions ?4. Is the review well-organised ? 5. Does the writer use the -ing form as the adverbial correctly in the writing ?6. Are there any grammar, spelling, or punctuation errors ?Step 9 HomeworkPut up your revised draft in the classroom or read it to your class.

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.

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.

    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!

    质疑问难,合作探究  1、文章是介绍沙子的知识吗?  明确:  有关恐龙灭绝的原因,原来本文的主角不是沙子,而是恐龙。  2、题目是《被压扁的沙子》,内容却恐龙灭绝的原因,题目《被压扁的沙子》是否偏离主题了?我们换成《恐龙是怎样灭绝的》会不会更好?  本文题目不但没有离题,还能提示读者,恐龙灭绝的“撞击说”所以产生,与被压扁的沙子的科学发现和科学研究密不可分此外,文题形象性强,容易激起好奇心,引起人们的阅读兴趣  3、恐龙灭绝的原因一直是学术界有争议的问题,因而产生两种学说“撞击说”“火山说”在探究恐龙灭绝的原因时,作者的观点是什么?他的观点以什么为依据,又是怎样推论出来的?

    检视整改,从字面上理解,包括两层含义,一是检视,就是查摆问题,分析原因,明确努力方向;二是整改,就是聚焦问题,靶向治疗,纠正工作偏差。这次主题教育检视整改形成了一些好机制。检视整改与其他重点措施有机融合、相互贯通。一个突出表现就是要求领导干部把调研发现的问题与推动发展遇到的问题、群众反映强烈的问题以及巡视巡察、审计监督等暴露的问题,一并列出问题清单进行整改,这既体现了边学习、边对照、边检视、边整改的要求,也有效解决了调查研究与检视整改相脱节的问题。开展性分析要求明确、特色鲜明。开展性分析,是严肃内政治生活的一项经常性工作。的十八届六中全会通过的《关于新形势下内政治生活的若干准则》中明确,“督促员对照章规定的员标准、对照入誓词、联系个人实际进行性分析”。
