    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.

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!

    教材分析連加、連減這部分內容是在100以內加減法的基礎上進行教學的,是前面所學計算方法的綜合練習。通過這部分內容的學習,可以進一步鞏固所學的100以內的加減法,提高計算能力。學生在一年級時已學過連加、連減的運算順序。因此,本節(jié)課的教學重點放在教學連加、連減的計算如何用豎式及豎式的簡便寫法計算。在復習這一環(huán)節(jié)中,我先設計了筆算兩位數(shù)加、減法的習題。目的是讓學生進一步鞏固兩位數(shù)加、減法的計算法則。然后通過兩道口算題復習連加、連減的運算順序。在進行例1的教學時,先讓學生觀察少先隊員幫農(nóng)民伯伯摘西瓜的情景圖,收集信息,提出數(shù)學問題引導學生列出算式。然后放手讓學生們嘗試算出結果。教師指出簡便寫法讓學生通過比較得出這種寫法的簡單所在。

    本課內容安排在學習了2—5的乘法口訣后,考慮到以后每次出現(xiàn)的口訣都比較多,而且較難記,所以學習乘加乘減也是為了幫助學生學習后面的乘法口訣。本課的教學內容有兩個特點:一是讓學生在實際生活中發(fā)現(xiàn)問題,為解決實際問題列出乘加、乘減的算式,并感受解決問題的策略和方法是多樣的,通過對各種方法的比較能進一步加強對乘法意義的理解;二是第一冊學生已經(jīng)學過了連加、連減,它的計算順序是從左到右,依次計算。本冊的乘加、乘減都是只教學乘法在前,加、減法在后的題型,計算順序同樣是從左至右;但在教學中,不能讓學生這樣說,而必須是學生明確要先算乘法,教材的設計就正是如此,沒把“先算乘法”作為運算順序機械的灌輸給學生,而是在現(xiàn)實的問題情境中聯(lián)系解題策略,使學生依據(jù)問題的情理確定先算乘法,真正明白算理。根據(jù)教材特點,制定如下教學目標知識目標:在實際問題的情境中感受乘加、乘減算式的意義,能用不同的方法解決問題,知道乘加乘減算式的運算順序。

    1、教學內容:人教版實驗教材二年級(上冊)77頁的例4。用乘法解決問題的教學滲透于掌握乘法口訣的教學過程中。教材在注重讓學生通過活動探索、理解乘法計算的含義和方法的同時,滲透用乘法解決問題的教學。在教學過7的乘法口訣之后,安排了有關“倍”概念的教學,以及如何用乘法解決有關倍的實際問題。2、教材的重點和難點:教材的重點是理解“求一個數(shù)的幾倍是多少”就是“求幾個幾是多少”。教材的難點是用乘法計算的解題思路。3、教學目標:1.進一步加深對“倍”的含義的理解。2.學會運用“求一個數(shù)的幾倍是多少”的方法解決實際問題,構建解決“求一個數(shù)的幾倍是多少”的問題的思維模式。3.初步學會分析數(shù)學信息與所求問題之間的聯(lián)系,學會看線段圖。
