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 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.

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.

教学过程【导入新课】在太阳系中，九大行星就好像一个家庭中的九个兄弟，有许多共性，今天，我们就一起来了解九大行星在运动特征和结构特征上的共同之处。【板书】3．九大行星的运动特征和结构特征【启发引导】请同学们一起阅读地图册上的“太阳系模式图”，读图分析：（1）九大行星在公转的方向、轨道等方面有什么共性？（2）图中符号“i”、“e”代表什么意思？这两组数字能说明什么问题？九大行星公转的方向相同，均为自西向东转，我们称为同向性。符号“i”表示轨道倾角。（简介黄道、黄道面、轨道倾角）各大 行星的轨道倾角都很小，只有水星和冥王星的大一些，最大也不过17°，说明九大行星的公转轨道近似在同一个平面上，我们称之为共面性。符号“e”代表公转轨道椭圆的偏心率，即焦点到椭圆中心的距离与椭圆半长轴之比，它决定椭圆的形状。偏心率越小，越趋向于圆，当偏心率为0时，轨道就是圆。

企业服装销售个人工作总结汇报范文3篇
一、顾客方面 我把进店的顾客分为两种： 第一种顾客，目的型的客人：逛商场怀有购物的目的，有比较明确的需求或者想法。她们可能开门见山或直奔主题索取自己喜欢的衣物，或者是半明确型的客人，是想买一件衬衫或外套，但是具体要买什么样貌还没有明确。 第二种顾客，闲逛型的顾客：此刻的商场里有太多消磨时光闲逛型的顾客，她们有的是纯粹打发时间，有的是情绪不好，到琳琅满目的商场里散心。闲逛型的顾客不必须是说不会购物，遇到她喜欢的和开心的货品时，下手也是毫不犹豫。目前商场里的顾客闲逛型的占多数，而对待闲逛型的顾客和有目的型顾客接待是不能完全相同的。闲逛型的顾客进店后，需要空间和时间来欣赏我们精心设计的漂亮陈列和货品。接待她们最忌讳的就是立刻接待，x%的时候你得到的回答是：我随便看看。显然这样的接待服务是有问题的。 二、工作方面 根据公司领导要求，做好店内的陈列及新款的展示，安排好人手更好的为公司的促销活动提升销售。定期及及时的做好竞争对手促销活动和款式变动的收集，第一时间反映到公司总部。做好会员基本资料的整理及定期跟踪，维护老客户，持续经常与老客户联系，了解客户对产品需求的动向，及时向店内的会员及老顾客反映公司的款式及店内的的优惠信息。合理的定货保证热卖及促销活动产品的库存，确保随时有货。 三、销售技巧方面 店员除了将服装展示给顾客，并加以说明之外，还要向顾客推荐服装，以引起顾客的购买的兴趣。推荐服装可运用下列方法： 首先推荐时要有信心，向顾客推荐服装时，营业员本身要有信心，才能让顾客对服装有信任感。适合于顾客的推荐。对顾客提示商品和进行说明时，应根据顾客的实际客观条件，推荐适合的服装。配合手势向顾客推荐。配合商品的特征。每类服装有不同的特征，如功能、设计、品质等方面的特征，向顾客推荐服装时，要着重强调服装的不同特征。 其次把话题集中在商品上。向顾客推荐服装时，要想方设法把话题引到服装上，同时注意观察顾客对服装的反映，以便适时地促成销售。准确地说出各类服装的优点。对顾客进行服装的说明与推荐时，要比较各类服装的不同，准确地说出各类服装的优点。
