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.

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑體部分在句中作表語(yǔ)。2. 句1、2、3中的that在從句中不作成分，只起連接作用。 Step2: Review the basic components of predicative clauses1.Definition

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.

新知講授（一）——隨機(jī)試驗(yàn) 我們把對(duì)隨機(jī)現(xiàn)象的實(shí)現(xiàn)和對(duì)它的觀察稱為隨機(jī)試驗(yàn)，簡(jiǎn)稱試驗(yàn)，常用字母E表示。我們通常研究以下特點(diǎn)的隨機(jī)試驗(yàn)：（1）試驗(yàn)可以在相同條件下重復(fù)進(jìn)行；（2）試驗(yàn)的所有可能結(jié)果是明確可知的，并且不止一個(gè)；（3）每次試驗(yàn)總是恰好出現(xiàn)這些可能結(jié)果中的一個(gè)，但事先不確定出現(xiàn)哪個(gè)結(jié)果。新知講授（二）——樣本空間思考一：體育彩票搖獎(jiǎng)時(shí)，將10個(gè)質(zhì)地和大小完全相同、分別標(biāo)號(hào)0，1，2，...，9的球放入搖獎(jiǎng)器中，經(jīng)過(guò)充分?jǐn)嚢韬髶u出一個(gè)球，觀察這個(gè)球的號(hào)碼。這個(gè)隨機(jī)試驗(yàn)共有多少個(gè)可能結(jié)果？如何表示這些結(jié)果？根據(jù)球的號(hào)碼，共有10種可能結(jié)果。如果用m表示“搖出的球的號(hào)碼為m”這一結(jié)果，那么所有可能結(jié)果可用集合表示{0，1，2，3，4，5，6，7，8，9}.我們把隨機(jī)試驗(yàn)E的每個(gè)可能的基本結(jié)果稱為樣本點(diǎn)，全體樣本點(diǎn)的集合稱為試驗(yàn)E的樣本空間。

大班數(shù)學(xué)《8的加法》說(shuō)課稿
本節(jié)課共分為五大環(huán)節(jié)來(lái)進(jìn)行教學(xué)的1、猜拳幼兒，激趣導(dǎo)入針對(duì)大班孩子純真幼稚、富于幻想的心理特征，因此上課一開(kāi)始進(jìn)行復(fù)習(xí)時(shí)，我設(shè)計(jì)了如下導(dǎo)語(yǔ)：小朋友們，智慧爺爺給你們帶禮物啦，表現(xiàn)好的都能得到，讓我們先來(lái)做一個(gè)猜拳游戲吧！點(diǎn)出復(fù)習(xí)題，在這種刺激下，人人都想當(dāng)老師眼中的小能手，興趣一下就調(diào)動(dòng)起來(lái)。2、創(chuàng)設(shè)情境，探究新知在新課學(xué)習(xí)中，通過(guò)孩子們所喜歡的卡通動(dòng)物形象-----小兔姐姐，以小兔姐姐邀請(qǐng)小朋友去郊游這一情境貫穿全課，從而激發(fā)幼兒學(xué)習(xí)新知的欲望。通過(guò)郊外蘋果樹(shù)上的蘋果，引導(dǎo)幼兒感知，探索1+7=87+1=8，并發(fā)現(xiàn)數(shù)量關(guān)系，理解算式的意義，然后出示小鴨圖，讓幼兒提出數(shù)學(xué)問(wèn)題，并列出算式2+6=86+2=83、觀察算式，發(fā)現(xiàn)加法交換律作為幼兒學(xué)習(xí)活動(dòng)的組織者、合作者和引導(dǎo)者，我讓幼兒通過(guò)小組討論的形式來(lái)發(fā)現(xiàn)算式的相同和不同之處，與幼兒一同歸納出：加號(hào)兩邊的數(shù)交換位置，得數(shù)不變。
大班數(shù)學(xué)《數(shù)的守恒》說(shuō)課稿
守恒包括數(shù)的守恒、長(zhǎng)度守恒、液量守恒、物質(zhì)的量(固體量)守恒、面積守恒、質(zhì)量守恒、容積守恒等。大班幼兒認(rèn)知活動(dòng)的具體形象性和行為的有意性明顯發(fā)展，能依靠表象進(jìn)行思維，認(rèn)知活動(dòng)的概括性使幼兒對(duì)事物的理解增強(qiáng)，但仍顯表面化、膚淺化。因此本次活動(dòng)選擇的內(nèi)容是網(wǎng)絡(luò)圖數(shù)守恒中的一個(gè)內(nèi)容6以內(nèi)數(shù)的守恒，旨在讓幼兒在游戲中愉快地學(xué)習(xí)數(shù)的守恒，通過(guò)自身的操作，初步感知物體位置發(fā)生變化，總數(shù)不變的數(shù)現(xiàn)象。讓幼兒在看一看、說(shuō)一說(shuō)、玩一玩、擺一擺中理解數(shù)的守恒，使幼兒對(duì)數(shù)的守恒有初步的概念。數(shù)的守恒是指物體數(shù)目不因物體外部特征和排列形式等的改變而改變，物體的數(shù)目與物體的大小、顏色、形狀及排列疏密沒(méi)有關(guān)系（評(píng)價(jià)標(biāo)準(zhǔn)：知道比較兩組物體的多少，要以物體的數(shù)目來(lái)判斷）。

大班幼兒形象思維方式發(fā)展已經(jīng)相當(dāng)好，邏輯思維也有了一定的發(fā)展，這一階段既是做好幼小銜接的重要階段，也是幼兒形成正確的學(xué)習(xí)方法和良好的學(xué)習(xí)習(xí)慣的關(guān)鍵時(shí)期。根據(jù)數(shù)學(xué)《3-6歲兒童學(xué)習(xí)與發(fā)展指南新課標(biāo)》的要求，結(jié)合幼兒的認(rèn)知規(guī)律，本次活動(dòng)我采用了以下三種方法：1、談話教學(xué)法：科學(xué)合理設(shè)計(jì)問(wèn)題，引導(dǎo)幼兒積極探索、思考。2、演示教學(xué)法：利用PPT進(jìn)行情境演示，讓幼兒更直觀的去理解9的加法。3、游戲教學(xué)法：幼兒活動(dòng)以游戲?yàn)橹鳎層變焊惺軘?shù)學(xué)的樂(lè)趣，喜歡數(shù)學(xué)活動(dòng)，感知數(shù)學(xué)與生活的聯(lián)系。
