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!
新人教版高中英语选修2Unit 2 Bridging Cultures-Discovering useful structures教学设计
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.

4．They were going to find someone to take part in their bet when they saw Henry walking on the street outside.[归纳]1．过去将来时的基本构成和用法过去将来时由“would＋动词原形”构成，主要表示从过去某一时间来看将要发生的动作(尤其用于宾语从句中)，还可以表示过去的动作习惯或倾向。Jeff knew he would be tired the next day.He promised that he would not open the letter until 2 o'clock.She said that she wouldn't do that again.2．表示过去将来时的其他表达法(1)was/were going to＋动词原形：该结构有两个主要用法，一是表示过去的打算，二是表示在过去看来有迹象表明将要发生某事。I thought it was going to rain.(2)was/were to＋动词原形：主要表示过去按计划或安排要做的事情。She said she was to get married next month.(3)was/were about to＋动词原形：表示在过去看来即将要发生的动作，由于本身已含有“即将”的意味，所以不再与表示具体的将来时间状语连用。I was about to go to bed when the phone rang.(4)was/were＋现在分词：表示在过去看来即将发生的动作，通常可用于该结构中的动词是come，go，leave，arrive，begin，start，stop，close，open，die，join，borrow，buy等瞬间动词。Jack said he was leaving tomorrow.
学习《未成年人保护法》个人心得体会范文精选
一是要提高教育者的法律意识，使教育者自觉遵守法律规定。了解法律并遵守法律，应落实到每一位教师在日常教学的具体行动中。 二是要了解并尊重未成年人的客观需要，不以教师的主观意愿去要求孩子。未成年人正处在生长发育的过程中，有其自身的需要和特点。比如孩子好动，不可能像成年人那样长时间安静地坐着不动。因此，教师应充分认识和理解未成年人发展的客观规律，不能凭者自己的主观意愿去看待孩子、要求孩子。
初中语文《社戏》试讲稿_教案设计
1 . 品味文章重点词语、句子或段落。 指导学生找出自己认为精彩、重要的词语、句子和段落，然后用旁批写下自己的看法。 词语例：“我们已经点开船，在桥石上一磕，退后几尺，即又上前出了桥。于是架起两支橹，一支两人，一里一换，……”“点”“磕”“退”“上”“架”等几个动词，将少年们开船时的动作程序以及合作划船的情状表述得颇为详细，显示了他们熟练的驾船技巧和勤劳肯干的品格，也折射出他们去看戏时的愉快心情。 句子例：“那航船，就像一条大白鱼背着一群孩子在浪花里蹿，连夜渔的几个老渔父，也停了艇子看着喝采起来。”这一句用一个富有童话色彩的比喻，反映了儿童富于幻想的 特点和愉快的心情。写老渔父的喝彩，是通过旁观者的赞美来衬托孩子们的驾船技术。 段落例：月夜行船一段（第11段）的景物描写分别从色彩、声音、视觉、听觉、嗅 觉各个侧面着笔，恰如多重奏管弦曲，给人以十分丰富的感觉，景物的立体感由此产生。
国旗下的讲话稿：做一个文明之人
这篇《国旗下的讲话稿：做一个文明之人》，是特地，希望对大家有所帮助！尊敬的各位领导、老师们、亲爱的同学们：早上好！今天我讲话的题目是《做一个文明之人》。在这里先给大家讲两个事例：个事例：新加坡是个以英语为通用语言的国家，据说他们的公共场所的各种标语大多是用英语书写的。但其中的一些涉及文明礼貌的标语，如“不准随地吐痰”、“禁止吸烟”、“不准进入草坪”等却用中文书写。这是为什么呢？人家回答：因为有这些不文明行为的大数是中国大陆的游客。为此，到新加坡考察的一位中学校长语重心长地说：不文明行为也是国耻。第二个事例：据中央电视台报道，国庆节后的天安门广场，随处可见口香糖残迹，显得格外刺眼，40万平方米的天安门广场上竟有60万块口香糖残渣，有的地方不到一平方米的地面上竟有9块口香糖污渍，密密麻麻的斑痕与天安门广场的神圣和庄严形成了强烈的反差。
倾斜角与斜率教学设计人教A版高中数学选择性必修第一册
(2)l的倾斜角为90°,即l平行于y轴,所以m+1=2m,得m=1.延伸探究1 本例条件不变,试求直线l的倾斜角为锐角时实数m的取值范围.解:由题意知(m"-" 1"-" 1)/(m+1"-" 2m)>0,解得1<m<2.延伸探究2 若将本例中的“N(2m,1)”改为“N(3m,2m)”,其他条件不变,结果如何?解:(1)由题意知(m"-" 1"-" 2m)/(m+1"-" 3m)=1,解得m=2.(2)由题意知m+1=3m,解得m=1/2.直线斜率的计算方法(1)判断两点的横坐标是否相等,若相等,则直线的斜率不存在.(2)若两点的横坐标不相等,则可以用斜率公式k=(y_2 "-" y_1)/(x_2 "-" x_1 )(其中x1≠x2)进行计算.金题典例 光线从点A(2,1)射到y轴上的点Q,经y轴反射后过点B(4,3),试求点Q的坐标及入射光线的斜率.解:(方法1)设Q(0,y),则由题意得kQA=-kQB.∵kQA=(1"-" y)/2,kQB=(3"-" y)/4,∴(1"-" y)/2=-(3"-" y)/4.解得y=5/3,即点Q的坐标为 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)设Q(0,y),如图,点B(4,3)关于y轴的对称点为B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由题意得,A、Q、B'三点共线.从而入射光线的斜率为kAQ=kAB'=-1/3.所以,有(1"-" y)/2=(1"-" 3)/(2+4),解得y=5/3,点Q的坐标为(0,5/3).
直线的两点式方程教学设计人教A版高中数学选择性必修第一册
解析：①过原点时，直线方程为y＝－34x.②直线不过原点时，可设其方程为xa＋ya＝1，∴4a＋－3a＝1，∴a＝1.∴直线方程为x＋y－1＝0.所以这样的直线有2条，选B.答案：B4.若点P(3,m)在过点A(2,-1),B(-3,4)的直线上,则m= . 解析:由两点式方程得,过A,B两点的直线方程为(y"-(-" 1")" )/(4"-(-" 1")" )=(x"-" 2)/("-" 3"-" 2),即x+y-1=0.又点P(3,m)在直线AB上,所以3+m-1=0,得m=-2.答案:-2 5.直线ax+by=1(ab≠0)与两坐标轴围成的三角形的面积是 . 解析:直线在两坐标轴上的截距分别为1/a 与 1/b,所以直线与坐标轴围成的三角形面积为1/(2"|" ab"|" ).答案:1/(2"|" ab"|" )6.已知三角形的三个顶点A(0,4)，B(－2,6)，C(－8,0)．(1)求三角形三边所在直线的方程；(2)求AC边上的垂直平分线的方程．解析(1)直线AB的方程为y－46－4＝x－0－2－0，整理得x＋y－4＝0；直线BC的方程为y－06－0＝x＋8－2＋8，整理得x－y＋8＝0；由截距式可知，直线AC的方程为x－8＋y4＝1，整理得x－2y＋8＝0.(2)线段AC的中点为D(－4,2)，直线AC的斜率为12，则AC边上的垂直平分线的斜率为－2，所以AC边的垂直平分线的方程为y－2＝－2(x＋4)，整理得2x＋y＋6＝0.
