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.

函數(shù)在高中數(shù)學(xué)中占有很重要的比重，因而作為函數(shù)的第一節(jié)內(nèi)容，主要從三個(gè)實(shí)例出發(fā)，引出函數(shù)的概念.從而就函數(shù)概念的分析判斷函數(shù)，求定義域和函數(shù)值，再結(jié)合三要素判斷函數(shù)相等.課程目標(biāo)1.理解函數(shù)的定義、函數(shù)的定義域、值域及對(duì)應(yīng)法則。2.掌握判定函數(shù)和函數(shù)相等的方法。3.學(xué)會(huì)求函數(shù)的定義域與函數(shù)值。數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象：通過(guò)教材中四個(gè)實(shí)例總結(jié)函數(shù)定義；2.邏輯推理：相等函數(shù)的判斷；3.數(shù)學(xué)運(yùn)算：求函數(shù)定義域和求函數(shù)值；4.數(shù)據(jù)分析：運(yùn)用分離常數(shù)法和換元法求值域；5.數(shù)學(xué)建模：通過(guò)從實(shí)際問(wèn)題中抽象概括出函數(shù)概念的活動(dòng)，培養(yǎng)學(xué)生從“特殊到一般”的分析問(wèn)題的能力，提高學(xué)生的抽象概括能力。重點(diǎn)：函數(shù)的概念，函數(shù)的三要素。難點(diǎn)：函數(shù)概念及符號(hào)y=f(x)的理解。
