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!?

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!

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.

师说教案
孔夫子被称为圣人，但他还是不耻下问，他曾以郯子、苌弘等人为师，他的学问绝对不比他们差，只是想学到其他他不会的知识罢了。他说：“三人行，必有我师焉。”民间俗语说：“三个臭皮匠，顶个诸葛亮。”的确是这样，不管是谁，都会有不懂的地方，例如，小学生做的数学智力题，有些连博士生都做不出来，就算你是大学中文系毕业的，也不会熟悉到字典里的每个字。人们的学问远远不如圣人，可他们也不肯向老师学习。这样的话，人又会有什么进步呢？老师无处不在，却往往被忽略，甚至耻笑。巫医、乐师和那些工匠们，经常互相学习。而那些士大夫们，自己没有学问，一听到有人称“老师”称“弟子”等等，就许多人聚在一块儿讥笑人家，还说：“他和他年龄差不多，道德学问也差不多啊，以地位低的人为师，就可羞耻，以官职高的人为师，就近乎谄媚！”听起来好像老师的标准都是他们定的！老师，可以是各个方面的传授者，却有人以向那些人学习为耻！
