T口 F口Step 5：After listening, discuss the questions.1 What kind of person do you think Chen Liyan is?Chen Liyan is generous and honest because she returned a large sum of money to the owner.2 Did Chen return the money because she didn't need it?No. She returned the money because it was the right thing to do. Evidence for this is that she refused to accept the reward money because she felt that it had not been earned. 3 Is it common for people to do what Chen did?It depends on the culture. In some countries it is quite common to return money that has been found. In other countries, people believe "Finders are keepers!" 4 How did Wang Zheng feel about the return of his money?He must have been very happy and relieved to have gotten his money back. We know this because he thanked Chen repeatedly and even offered her a reward.5 Why did Ma Dongbao tell Wang about Chen's family?He must have had great sympathy for Chen and her daughter and wanted to help them.'We know this because he arranged help for them. 6 How did the news reporter feel about Chen's actions?The news reporter felt that it showed that money wasn't the most important thing in life. We know this because the reporter told us that this is what Chen believes. and then said, “that's a great attitude to take."

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

【高教版】中職數(shù)學(xué)拓展模塊：3.2《二項(xiàng)式定理》教學(xué)設(shè)計(jì)
一、定義： ，這一公式表示的定理叫做二項(xiàng)式定理，其中公式右邊的多項(xiàng)式叫做的二項(xiàng)展開式；上述二項(xiàng)展開式中各項(xiàng)的系數(shù) 叫做二項(xiàng)式系數(shù)，第項(xiàng)叫做二項(xiàng)展開式的通項(xiàng)，用表示；叫做二項(xiàng)展開式的通項(xiàng)公式．二、二項(xiàng)展開式的特點(diǎn)與功能1. 二項(xiàng)展開式的特點(diǎn)項(xiàng)數(shù)：二項(xiàng)展開式共（二項(xiàng)式的指數(shù)+1）項(xiàng)；指數(shù)：二項(xiàng)展開式各項(xiàng)的第一字母依次降冪（其冪指數(shù)等于相應(yīng)二項(xiàng)式系數(shù)的下標(biāo)與上標(biāo)的差），第二字母依次升冪（其冪指數(shù)等于二項(xiàng)式系數(shù)的上標(biāo)），并且每一項(xiàng)中兩個(gè)字母的系數(shù)之和均等于二項(xiàng)式的指數(shù)；系數(shù)：各項(xiàng)的二項(xiàng)式系數(shù)下標(biāo)等于二項(xiàng)式指數(shù)；上標(biāo)等于該項(xiàng)的項(xiàng)數(shù)減去1（或等于第二字母的冪指數(shù)；2. 二項(xiàng)展開式的功能注意到二項(xiàng)展開式的各項(xiàng)均含有不同的組合數(shù)，若賦予a，b不同的取值，則二項(xiàng)式展開式演變成一個(gè)組合恒等式．因此，揭示二項(xiàng)式定理的恒等式為組合恒等式的“母函數(shù)”，它是解決組合多項(xiàng)式問題的原始依據(jù)．又注意到在的二項(xiàng)展開式中，若將各項(xiàng)中組合數(shù)以外的因子視為這一組合數(shù)的系數(shù)，則易見展開式中各組合數(shù)的系數(shù)依次成等比數(shù)列．因此，解決組合數(shù)的系數(shù)依次成等比數(shù)列的求值或證明問題，二項(xiàng)式公式也是不可或缺的理論依據(jù)．
