⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

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.

反比例函數(shù)教案教學設(shè)計
本節(jié)的內(nèi)容主要是反比例函數(shù)的概念教學.反比例函數(shù)概念的建立，不能從形式上進行簡單的抽象與概括，而是對這些實例從不同角度抽象出本質(zhì)屬性后，再進行概括。教材設(shè)計的基本思路是從現(xiàn)實生活中大量的反比例關(guān)系中抽象出反比例函數(shù)概念，讓學生進一步感受函數(shù)是反映現(xiàn)實世界中變量關(guān)系的一種有效數(shù)學模型，逐步從對具體反比例函數(shù)的感性認識上升到對抽象的反比例函數(shù)概念的理性認識. 同時本節(jié)的學習內(nèi)容，直接關(guān)系到本章后續(xù)內(nèi)容的學習，也是繼續(xù)學習其它各類函數(shù)的基礎(chǔ)，其中蘊涵的類比、歸納、對應和函數(shù)的數(shù)學思想方法，對學生今后研究問題、解決問題以及終身的發(fā)展都是非常有益的.基于以上分析，本節(jié)教學設(shè)計是建立在一個個數(shù)學活動的基礎(chǔ)上，經(jīng)過對情境理解、本質(zhì)抽象的積累而形成的.讓學生對一類問題情境中兩個變量間的關(guān)系，在充分經(jīng)歷寫表達式，計算函數(shù)值和觀察函數(shù)值隨自變量變化規(guī)律的過程中，逐步概括形成反比例函數(shù)的概念.針對教學實際，我選取了貼學生現(xiàn)實的，有價值的實例“文具店里買學習用品”和“剪面積為定值的長方形紙片”等作為問題情境.
