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.

二、探究新知一、点到直线的距离、两条平行直线之间的距离1.点到直线的距离已知直线l的单位方向向量为μ,A是直线l上的定点,P是直线l外一点.设(AP) ?=a,则向量(AP) ?在直线l上的投影向量(AQ) ?=(a·μ)μ.点P到直线l的距离为PQ=√(a^2 "-(" a"·" μ")" ^2 ).2.两条平行直线之间的距离求两条平行直线l,m之间的距离,可在其中一条直线l上任取一点P,则两条平行直线间的距离就等于点P到直线m的距离.点睛：点到直线的距离,即点到直线的垂线段的长度,由于直线与直线外一点确定一个平面,所以空间点到直线的距离问题可转化为空间某一个平面内点到直线的距离问题.1.已知正方体ABCD-A1B1C1D1的棱长为2,E,F分别是C1C,D1A1的中点,则点A到直线EF的距离为 . 答案: √174/6解析:如图,以点D为原点,DA,DC,DD1所在直线分别为x轴、y轴、z轴建立空间直角坐标系,则A(2,0,0),E(0,2,1),F(1,0,2),(EF) ?=(1,-2,1),
