一、定义： ，这一公式表示的定理叫做二项式定理，其中公式右边的多项式叫做的二项展开式；上述二项展开式中各项的系数 叫做二项式系数，第项叫做二项展开式的通项，用表示；叫做二项展开式的通项公式．二、二项展开式的特点与功能1. 二项展开式的特点项数：二项展开式共（二项式的指数+1）项；指数：二项展开式各项的第一字母依次降幂（其幂指数等于相应二项式系数的下标与上标的差），第二字母依次升幂（其幂指数等于二项式系数的上标），并且每一项中两个字母的系数之和均等于二项式的指数；系数：各项的二项式系数下标等于二项式指数；上标等于该项的项数减去1（或等于第二字母的幂指数；2. 二项展开式的功能注意到二项展开式的各项均含有不同的组合数，若赋予a，b不同的取值，则二项式展开式演变成一个组合恒等式．因此，揭示二项式定理的恒等式为组合恒等式的“母函数”，它是解决组合多项式问题的原始依据．又注意到在的二项展开式中，若将各项中组合数以外的因子视为这一组合数的系数，则易见展开式中各组合数的系数依次成等比数列．因此，解决组合数的系数依次成等比数列的求值或证明问题，二项式公式也是不可或缺的理论依据．

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.
