Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

1. 這個寓言是一個關(guān)于一位國王古寓言。 The fable is an old fable about a king.2.作者用這個故事讓讀者對于社區(qū)的問題負有個人責任的必要印象深刻。The author used the story to impress upon readers with the need to take personal responsibility for problems in the community.3. 這個故事十分成功的實現(xiàn)了它的目的。The story was quite successful in achieving its purpose.Step 7 WritingPlease write a review of the story according the outline above.The fable is an old fable about a king who thought his people are lazy, so he put a large stone in the middle of the road and hides and waited to see if anyone will try to move it.The author used this story to impress upon readers with the need to take personal responsibility for problems in the community. The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner. Use this checklist to help your partner revise his/her draft.1. Does the writer give a short description of the story ?2. Does the description include the most important details of the story ?3. Does the writer give his or her opinion about the character or their actions ?4. Is the review well-organised ? 5. Does the writer use the -ing form as the adverbial correctly in the writing ?6. Are there any grammar, spelling, or punctuation errors ?Step 9 HomeworkPut up your revised draft in the classroom or read it to your class.
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。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!

二、探究新知一、點到直線的距離、兩條平行直線之間的距離1.點到直線的距離已知直線l的單位方向向量為μ,A是直線l上的定點,P是直線l外一點.設(shè)(AP) ?=a,則向量(AP) ?在直線l上的投影向量(AQ) ?=(a·μ)μ.點P到直線l的距離為PQ=√(a^2 "-(" a"·" μ")" ^2 ).2.兩條平行直線之間的距離求兩條平行直線l,m之間的距離,可在其中一條直線l上任取一點P,則兩條平行直線間的距離就等于點P到直線m的距離.點睛:點到直線的距離,即點到直線的垂線段的長度,由于直線與直線外一點確定一個平面,所以空間點到直線的距離問題可轉(zhuǎn)化為空間某一個平面內(nèi)點到直線的距離問題.1.已知正方體ABCD-A1B1C1D1的棱長為2,E,F分別是C1C,D1A1的中點,則點A到直線EF的距離為 . 答案: √174/6解析:如圖,以點D為原點,DA,DC,DD1所在直線分別為x軸、y軸、z軸建立空間直角坐標系,則A(2,0,0),E(0,2,1),F(1,0,2),(EF) ?=(1,-2,1),
二、探究新知一、空間中點、直線和平面的向量表示1.點的位置向量在空間中,我們?nèi)∫欢cO作為基點,那么空間中任意一點P就可以用向量(OP) ?來表示.我們把向量(OP) ?稱為點P的位置向量.如圖.2.空間直線的向量表示式如圖①,a是直線l的方向向量,在直線l上取(AB) ?=a,設(shè)P是直線l上的任意一點,則點P在直線l上的充要條件是存在實數(shù)t,使得(AP) ?=ta,即(AP) ?=t(AB) ?.如圖②,取定空間中的任意一點O,可以得到點P在直線l上的充要條件是存在實數(shù)t,使(OP) ?=(OA) ?+ta, ①或(OP) ?=(OA) ?+t(AB) ?. ②①式和②式都稱為空間直線的向量表示式.由此可知,空間任意直線由直線上一點及直線的方向向量唯一確定.1.下列說法中正確的是( )A.直線的方向向量是唯一的B.與一個平面的法向量共線的非零向量都是該平面的法向量C.直線的方向向量有兩個D.平面的法向量是唯一的答案:B 解析:由平面法向量的定義可知,B項正確.
整體感知 齊誦詩歌,說說這首詩歌緊扣“土地”,作了哪些形象性的描述?! 窘涣鼽c撥】點出土地情結(jié)。起始兩句,詩人對土地的熱愛,已到了不知道如何傾訴的地步,于是他舍棄人的思維語言而借用鳥的簡單樸素的語言傾瀉他的感情?!八粏 钡母杪曊苁惆l(fā)作者對土地的義無反顧的眷戀和執(zhí)著,于是土地情結(jié)的激越歌聲由此響起?! A吐土地情結(jié)?!氨槐╋L雨所打擊著的土地”“悲憤的河流”“激怒的風”“無比溫柔的黎明”是作者所歌唱的對象,詩人沒有沉溺于對“溫柔”恬靜的“黎明”的欣賞中,為了讓自己的愛永遠留給土地,他做出了莊嚴鄭重的選擇?! ∩A土地情結(jié)。一問一答,詩人由借鳥抒情轉(zhuǎn)入直抒胸臆。太“深沉”太強烈的土地情結(jié),已使人難以訴諸語言,只能凝成晶瑩的淚水?!吧畛痢币辉~也許達不到與實際感情相適應(yīng)的強度,于是其后緊跟著沉重的省略號。省略號中似乎涌動著潛流地火一般的激情,更為沉重地叩擊著讀者的心房,激起讀者持續(xù)的共鳴。

從《詩經(jīng)》的現(xiàn)實主義到屈原的浪漫主義,是中國詩歌發(fā)展的一個里程碑。屈原的騷體詩,依詩取興,引類譬喻,繼承發(fā)展了《詩經(jīng)》的比興傳統(tǒng)?!对娊?jīng)》的比興較為單純,而《楚辭》的比興具有象征的特質(zhì),往往成為一個形象的系統(tǒng)。《離騷》中香草美人的比興就是范例。楚地本是澤鄉(xiāng)山國,其間頗有疊波曠宇、崇山秀嶺,這些江山的光怪之氣足以搖蕩心靈、催發(fā)麗辭偉句。但騷體詩已沖破《詩經(jīng)》四言詩的固定格式,句式加長而靈活,篇章放大而嚴密,詩采絢麗而貼切,是《詩經(jīng)》之后的一次詩體大解放。有人說,中國歷代詩“莫不同祖風騷”,足見其對后代詩歌的影響。先秦時代,《詩經(jīng)》與《楚辭》雙峰并峙,是中國詩史上現(xiàn)實主義與浪漫主義的兩座巍然屹立的坐標。
1.本文由“不得極夫游之樂”生發(fā)出“盡吾志”的觀點,又由“仆碑”生發(fā)出“深思慎取”的觀點,這兩個觀點彼此有聯(lián)系嗎?作者游褒禪山,本來是一次平常的游歷活動,但卻從中悟出了人生哲理──從前洞后洞游人的多少悟出“夷以近,則游者眾;險以遠,則至者少”,從“入之愈深,其進愈難,而其見愈奇”悟出“而世之奇?zhèn)?、瑰怪、非常之觀,常在于險遠”;由此再引申一步,就得出了“非有志者不能至”的結(jié)論。然后將這次游山而未能“極夫游之樂”的教訓升華到理論上來,具體分析了“至”的幾個條件,最后得出“盡吾志”的觀點──這正是“求思之深而無不在”的結(jié)果。由此可見,“盡吾志”的觀點跟“深思慎取”的觀點是有聯(lián)系的:“盡吾志”的觀點是在“深思慎取”的基礎(chǔ)上產(chǎn)生的;有了這個觀點,又能反過來促使人們“深思慎取”,二者是相輔相成的。
