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.

人教版新课标小学数学二年级上册求一个数的几倍是多少 说课稿
1、教学内容：人教版实验教材二年级（上册）77页的例4。用乘法解决问题的教学渗透于掌握乘法口诀的教学过程中。教材在注重让学生通过活动探索、理解乘法计算的含义和方法的同时，渗透用乘法解决问题的教学。在教学过7的乘法口诀之后，安排了有关“倍”概念的教学，以及如何用乘法解决有关倍的实际问题。2、教材的重点和难点：教材的重点是理解“求一个数的几倍是多少”就是“求几个几是多少”。教材的难点是用乘法计算的解题思路。3、教学目标：1.进一步加深对“倍”的含义的理解。2.学会运用“求一个数的几倍是多少”的方法解决实际问题，构建解决“求一个数的几倍是多少”的问题的思维模式。3.初步学会分析数学信息与所求问题之间的联系，学会看线段图。

针对案列中的基于文本的警示标签是否有效，其实不管在什么地方大街上、超市内、店铺门口、公共场所等很多地方都会看到各式各样的标签图，有的是单单的警示文字、有的是一张警示图片，基于案例中所提到的哪个更具有效果，人们走在路上或者去公园玩耍看警示标语一般看图片的影响比看文字的影响大得多，如果警示标签仅仅是文字说明，大多数人都不会看的，但如果是生动的图片大多数人都会有一种警示。所以作为食品行业的制造者们食品安全行为要始终牢牢扎根在我们心中，要真正的意识到食安文化不是一个人的问题，而是你中有我，我中有你，人人互保、环环相扣的链。让我们每个人都可以成为合格的食品安全制造者，制造出合格、安全、放心的产品，作为食品行业的行为榜样。

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!

关于食品安全的注意事项的国旗下的讲话
食品安全记心间同学们：炎热的夏天到了，“民以食为天，食以安为先”，食品安全问题涉及到每个人的身体健康和生命，不安全的隐患就在我们身边。同学们，你们是祖国的花朵，是祖国的未来，是早上八九点钟的太阳，是祖国发展和平富强的希望;你们每天吃的方便面是合格食品吗？每天吃的肉类是符合卫生标准食品吗？每天喝的矿泉水饮料是在有效保质期之内吗？每天吃的面包有厂名、厂址、生产日期、合格证吗？妈妈每天给你喝的牛奶有qs标志吗？有些人在平时吃到、买到的食品只是没有留心注意到这些。那么在平时日常生活中吃到、买到不合格食品应该向谁投诉举报呢？带着这些在我们自己身边日常生活中经常遇到的食品安全的小问题，借此机会给大家讲一讲食品安全方面的知识。1、什么叫食品安全？食品安全（foodsafety）指食品无毒、无害，符合应当有的营养要求，对人体健康不造成任何急性、亚急性或者慢性危害。根据世界卫生组织的定义，食品安全是“食物中有毒、有害物质对人体健康影响的公共卫生问题”。食品安全也是一门专门探讨在食品加工、存储、销售等过程中确保食品卫生及食用安全，降低疾病隐患，防范食物中毒的一个跨学科领域。
