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.

將口袋縫制在肘后，雖然拿東西也很不方便，但因在口袋里盛裝的只能是些細(xì)小、輕便的貴重物品，加之袖子比較寬大，手伸到袖內(nèi)口袋里取物，也還是可以輕易做到的。如：東晉時(shí)期的醫(yī)學(xué)家葛洪廣泛收集當(dāng)時(shí)民間流傳的用于常見病的處方后，編成《肘后備急方》。其書的名稱就使用了“肘后”一詞，意在表明書是放在肘后的口袋中，是可以隨身攜帶、查閱的，具有應(yīng)急救助的寓義。由此也說明，古人上衣中的口袋位置是在袖內(nèi)的肘后。
人教版新課標(biāo)高中物理必修1摩擦力說課稿2篇
本節(jié)課是人教社物理必修1第三章第三節(jié)的內(nèi)容，編排在彈力之后。該節(jié)知識(shí)既是力學(xué)的基礎(chǔ)，也是組成整個(gè)高中物理知識(shí)的一塊“基石”，所以這節(jié)內(nèi)容的教學(xué)如何引領(lǐng)學(xué)生自主積極地探究摩擦力產(chǎn)生的條件和影響因素，體驗(yàn)?zāi)Σ亮μ攸c(diǎn)規(guī)律的發(fā)生過程是本節(jié)課的重點(diǎn)，應(yīng)高度重視本節(jié)教學(xué)過程；由于摩擦力問題的復(fù)雜性，且在具體問題中又表現(xiàn)出“動(dòng)中有靜，靜中有動(dòng)”，尤其靜摩擦在許多情形下似乎又是“若有若無，方向不定”，因此，對(duì)于初學(xué)者也是有一定難度的。也正是由于教材內(nèi)容的上述特點(diǎn)，本節(jié)課又易于激起學(xué)生的求知欲，易于培養(yǎng)學(xué)生的辯證觀點(diǎn)，易于錘煉學(xué)生的物理素質(zhì)。要充分用好該節(jié)教材內(nèi)容，深入挖掘知識(shí)間的有機(jī)聯(lián)系，對(duì)學(xué)生開展針對(duì)性的思維訓(xùn)練，進(jìn)而提高學(xué)生應(yīng)用物理知識(shí)解決實(shí)際問題的能力和創(chuàng)新思維能力。高中物理《課標(biāo)》對(duì)該知識(shí)點(diǎn)的要求是，“通過實(shí)驗(yàn)認(rèn)識(shí)滑動(dòng)摩擦、靜摩擦的規(guī)律，能用動(dòng)摩擦因數(shù)計(jì)算摩擦力”。其中，對(duì)靜摩擦力規(guī)律的認(rèn)識(shí)應(yīng)該包括最大靜摩擦力。
