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

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:?

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.

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.

當(dāng)A,C顏色相同時(shí),先染P有4種方法,再染A,C有3種方法,然后染B有2種方法,最后染D也有2種方法.根據(jù)分步乘法計(jì)數(shù)原理知,共有4×3×2×2=48(種)方法;當(dāng)A,C顏色不相同時(shí),先染P有4種方法,再染A有3種方法,然后染C有2種方法,最后染B,D都有1種方法.根據(jù)分步乘法計(jì)數(shù)原理知,共有4×3×2×1×1=24(種)方法.綜上,共有48+24=72(種)方法.故選B.答案:B5.某藝術(shù)小組有9人,每人至少會(huì)鋼琴和小號(hào)中的一種樂(lè)器,其中7人會(huì)鋼琴,3人會(huì)小號(hào),從中選出會(huì)鋼琴與會(huì)小號(hào)的各1人,有多少種不同的選法?解:由題意可知,在藝術(shù)小組9人中,有且僅有1人既會(huì)鋼琴又會(huì)小號(hào)(把該人記為甲),只會(huì)鋼琴的有6人,只會(huì)小號(hào)的有2人.把從中選出會(huì)鋼琴與會(huì)小號(hào)各1人的方法分為兩類(lèi).第1類(lèi),甲入選,另1人只需從其他8人中任選1人,故這類(lèi)選法共8種;第2類(lèi),甲不入選,則會(huì)鋼琴的只能從6個(gè)只會(huì)鋼琴的人中選出,有6種不同的選法,會(huì)小號(hào)的也只能從只會(huì)小號(hào)的2人中選出,有2種不同的選法,所以這類(lèi)選法共有6×2=12(種).因此共有8+12=20(種)不同的選法.

關(guān)于品德是人的第一智慧的第三周?chē)?guó)旗下講話
德是人的第一智慧—第三周?chē)?guó)旗下講話各位老師、同學(xué)們：大家早晨好！我今天講話的題目是《品德是人的第一智慧》，側(cè)重闡述品德和智慧的關(guān)系，強(qiáng)調(diào)我校學(xué)生在校期間的品德要求。我們今天培養(yǎng)和選拔人才的標(biāo)準(zhǔn)是德才兼?zhèn)洌苌儆腥怂伎肌暗隆焙汀安拧钡年P(guān)系?？梢赃@樣講，一個(gè)人有怎樣的品德，就會(huì)有怎樣的人生理解和目標(biāo)，而智慧決定的是追求目標(biāo)的途徑和方法。目標(biāo)決定方法，方法服務(wù)于目標(biāo)。從這個(gè)意義上講，品德是成功人生的前提，是第一位的；智慧是成功人生的必須，從屬于品德。翻開(kāi)一部人類(lèi)的歷史，凡被人們敬仰的偉人，哪一位不是品德高尚的人？毛澤東、孫中山、錢(qián)學(xué)森、華羅庚、羅斯福、華盛頓、愛(ài)因斯坦、哥白尼等等。同學(xué)們?cè)囅胂?，如果你走向社?huì)后事業(yè)有成，你會(huì)選擇一位當(dāng)年缺乏公德的同學(xué)合作嗎？沒(méi)有與人良好的合作關(guān)系，才高八斗又有何用？高尚的品德不是與生俱來(lái)的，他需要我們一點(diǎn)一滴的做好自律，并自覺(jué)接受它律。自律的最高境界就是中國(guó)儒家文化強(qiáng)調(diào)的“慎獨(dú)”，即一個(gè)人獨(dú)處時(shí)也能保持同樣的高尚品德境界，而不是沒(méi)人看見(jiàn)就隨手扔垃圾，隨性破壞公物或干點(diǎn)什么見(jiàn)不得人的壞事。
第三周?chē)?guó)旗下講話稿：抓常規(guī)管理 促進(jìn)養(yǎng)成教育
第三周?chē)?guó)旗下講話稿：抓常規(guī)管理促進(jìn)養(yǎng)成教育老師們、同學(xué)們，大家早上好！今天我國(guó)旗下講話的題目是：《抓常規(guī)管理促進(jìn)養(yǎng)成教育》。打造一個(gè)優(yōu)秀的集體，需要抓常規(guī)管理，促進(jìn)養(yǎng)成教育。我認(rèn)為：首先，要建章立規(guī)細(xì)化要求俗話說(shuō)：沒(méi)有規(guī)矩不成方圓，常規(guī)管理的前提是制定常規(guī)，只有確立了學(xué)生的日常行為的規(guī)范，才能使學(xué)生的精力更多地放在學(xué)習(xí)上，而不是物質(zhì)追求上，不是放在那些無(wú)關(guān)學(xué)習(xí)的事情上。只有抓好了常規(guī)管理，才會(huì)有效約束學(xué)生的行為習(xí)慣與學(xué)習(xí)習(xí)慣，從而逐步形成良好的學(xué)風(fēng)、班風(fēng)、校風(fēng)。常規(guī)管理要具體化，給學(xué)生以非常明確具體的要求，可以使學(xué)生更加有章可循，讓學(xué)生樹(shù)立道德感、責(zé)任感、尊嚴(yán)感，端正學(xué)習(xí)態(tài)度，學(xué)習(xí)更主動(dòng)更自然，在具體操作時(shí)，可精細(xì)到每個(gè)細(xì)節(jié)，做到定人、定點(diǎn)、定時(shí)、定事。其次，要強(qiáng)化訓(xùn)練促進(jìn)養(yǎng)成學(xué)生是日常管理的對(duì)象，更是常規(guī)管理的主體，為此，我們以班級(jí)教育、自我教育、傳授教育為主渠道，訓(xùn)練學(xué)生自我約束，自我管理的能力
全市旅游產(chǎn)業(yè)發(fā)展工作推進(jìn)會(huì)上的講話
在看到成績(jī)的同時(shí)，我們也要清醒地認(rèn)識(shí)到存在的問(wèn)題和不足。一是全市旅游景區(qū)業(yè)態(tài)單一，產(chǎn)品同質(zhì)化嚴(yán)重、特色化挖掘不夠以及運(yùn)營(yíng)能力不強(qiáng)等問(wèn)題突出。比如，甕安古邑旅游區(qū)、惠水好花紅旅游區(qū)如何發(fā)揮良好效益，還需要深入研究推動(dòng)。二是全市旅游業(yè)仍以觀光旅游產(chǎn)品為主，產(chǎn)業(yè)鏈條不長(zhǎng)，休閑度假溫泉、度假酒店、旅居村寨等康養(yǎng)、體驗(yàn)產(chǎn)品較少，供給不足，“+旅游”這篇大文章做得不夠，統(tǒng)籌還不到位。三是全市大多數(shù)景區(qū)仍以政府主導(dǎo)為主，不善于謀劃和經(jīng)營(yíng)，產(chǎn)出賬算的還不夠，造成了一些爛尾項(xiàng)目、僵尸項(xiàng)目。四是旅游營(yíng)銷(xiāo)不夠精準(zhǔn)高效，大多還停留在傳統(tǒng)營(yíng)銷(xiāo)推介模式，利用新媒體宣傳營(yíng)銷(xiāo)還有差距，客源地、目標(biāo)市場(chǎng)定位還不夠精準(zhǔn)，特別是在細(xì)分目標(biāo)市場(chǎng)和客群市場(chǎng)上做得還不夠。
在全縣旅游興縣工作會(huì)議上的講話
一是旅游業(yè)地位不斷提升。近年來(lái)，縣委、縣政府把旅游業(yè)作為最具潛力的新興產(chǎn)業(yè), 擺上重要工作日程。制定并印發(fā)了《X縣關(guān)于加快發(fā)展大旅游產(chǎn)業(yè)的實(shí)施意見(jiàn)》，不斷優(yōu)化發(fā)展思路，強(qiáng)化工作措施，實(shí)施重點(diǎn)項(xiàng)目，全縣旅游產(chǎn)業(yè)呈持續(xù)向好的喜人態(tài)勢(shì)。
