Father's
Day is a fairly new celebration in the British calendar compared with Mother's
Day, which has been a very popular and well celebrated festival in the
Father’s Day was first celebrated by American 36 it was inspired by the actions of a man named William Smart. He was a veteran（退伍軍人）of the US Civil War and his wife 37 away giving birth to their sixth child. He 38 six children alone without remarrying, which was undoubtedly 39 back in those days.
His daughter, Sonora Dodd, 40 when she was an adult what her father had sacrificed for his 41 . It was in the early 1900s and she was actually 42 one day, listening to a sermon（傳教） on 43 . She thought there should 44 be a Father's Day celebration.
And so
the 45 was born, on the third Sunday every June,
close to the anniversary of
Father's Day is never quite such the big commercial event 47 Mother's Day is, probably because it hasn't been in 48 for so long. But what do British people do for Father's Day?

Card shops will be full of mugs or pens and similar goods with “World's Greatest Dad” 53 on them.
Some families 54 do things together to celebrate Father's Day like going for a meal. As a special treat, British people might give their Dad a bit of a rest , 55 him a cup of tea, or even wash his car and mow the lawn（除草） to make him feel really appreciated.

I am one of the many city people who are always saying that given the choice we would prefer to live in the country away from the dirt and noise of a large city. I have managed to convince myself that if it weren’t for my job I would immediately head out for the open spaces and go back to nature in some sleepy village buried in the country. But how realistic is the dream?
Cities can be frightening places. The majority of the population live in massive tower blocks, noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when you live fifteen floors up. All you can see from your window is sky, or other blocks of fiats.
Strangely enough, whereas in the past the inhabitants of one street all knew each other, nowadays people on the same floor in tower blocks don’t even say hello to each other.
Country life, on the other hand, differs from this kind of isolated（隔離）existence because a sense of community generally ties the inhabitants of small villages together. But country life has disadvantages too. It is true that you are cut off from the exciting and important events that take place in cities. There’s little possibility of going to a new show or the latest movie. Shopping becomes a major problem, and for anything slightly out of the ordinary you have to go on an expedition to the nearest large town. The city-people who leave for the country are often oppressed by a sense of unbearable stillness and quietness.
What , then , of my dreams of leaning on a cottage gate and murmuring “morning” to the locals as they pass by? I’m eager for the idea, but you see there’s my cat, Toby. I’m not at all sure that he would take to all that fresh air and exercise in the long grass. I mean, can you see him mixing with all those hearty males down the farm? No, he would rather have the electric fire any evening.
63. We learn from Paragraph I that the writer________.
A. used to live in the country B. used to work in the city
C. works in the city D. lives in the country
64. In the writer’s opinion , the following may cause city people to be unhappy EXCEPT_______.
A. a strong sense of fear B. a lack of communication
C. housing conditions D. a sense of isolation
65. The text implies that it is not easy to buy ______ in the country.
A. agricultural produce B. fresh fruits C. fresh vegetables D. designed clothes
66. The passage manly talks about_______
A. the advantages of living in cities
B. the difference between living in cities and villages
C. most people prefer to live in cities D. the advantages of living in villages

教學過程設計
教師活動
【復習引入】上節課我們主要復習了有機反應的類型，與有機物合成有關的重要反應規律有哪幾點呢？
【追問】每一規律的反應機理是什么？
（對學生們的回答評價后，提出問題）
【投影】
①雙鍵斷裂一個的原因是什么？
②哪種類型的醇不能發生氧化反應而生成醛或酮？
③哪種類型的醉不能發生消去反應而生成烯烴？
④酯化反應的機理是什么？
⑤什么樣的物質可以發生成環反應？對學生的回答進行評價或補充。
學生活動
思考、回憶后，回答：共5點。
①雙鍵的加成和加聚；
②醇和鹵代烴的消去反應；
③醇的氧化反應；
④酯的生成和水解及肽鍵的生成和水解；
⑤有機物成環反應。
討論后，回答。
積極思考，認真討論，踴躍發言。
答：①雙鍵的鍵能不是單鍵鍵能的兩倍，而是比兩倍略少。因此，只需要較少的能量就能使雙鍵里的一個鍵斷裂。
②跟―OH相連的碳原子與3個碳原子相連的醇一般不能被氧化成醛或酮；
③所在羥基碳原子若沒有相鄰的碳原子（如CH3OH）或相鄰碳原子上沒有氫原子[如（CH3）3CCH2OH]的醇（或鹵代烴）不能發生消去反應而生成不飽和烴；
④酯化反應的機理是：羧酸脫羥基，醇脫氫。
⑤能發生有機成環的物質是：二元醇脫水、羥基酸酯化、氨基酸脫水、二元羧酸脫水。
【提問】衡量一個國家的石油化工業發展水平的標志是什么？為什么？
回答：常把乙烯的年產量作為衡量一個國家石油化工發展水平的標志。
原因是：乙烯是有機化工原料，在合成纖維工業、塑料工業、橡膠工業、醫藥等方面得到廣泛應用。
【評價后引入】今天我們來復習有機物的合成。
【板書】有機合成
【講述】下面讓我們一起做第一道題，請同學們思考有機合成中合成路線的合理設計的關鍵是什么？應從哪些方面入手？
【投影】
例1 用乙炔和適當的無機試劑為原料，合成 
。
資料1
資料2
傾聽，明確下一步的方向。
展開討論：
從原料到產品在結構上產生兩種變化：
①從碳鏈化合物變為芳環化合物；
②官能團從“―C≡C―”變為“―Br”。由順推法可知：由乙炔聚合可得苯環，如果由苯直接溴代，只能得到溴苯，要想直接得到均三溴苯很難。我們只能采取間接溴代的方法，即只有將苯先變為苯酚或苯胺，再溴代方可；而三溴苯酚中的“―OH”難以除去。而根據資料2可知， 
中的“―NH2”可通過轉化為重氮鹽，再進行放氮反應除去。
板演方程式：
【評價】大家分析得很全面，也很正確。現將可行方案中所涉及到的有關反應方程式按順序寫出。請兩名同學到黑板來寫，其他同學寫在筆記本上。
【評價】兩名學生書寫正確。
【提問】對比這兩道小題，同學們想一想，設計合成有機物的路線時，主要應從哪里進行思考呢？
分析、對比、歸納出：
①解題的關鍵是找出原料與產品的結構差別是什么，然后在熟知物質性能的基礎上尋找解決問題的途徑即合成路線。
②在解題時應考慮引入新的官能團，能否直接引入，間接引入的方法是什么？這些問題的解決就需要我們熟練掌握有機物的特征反應。

【板書】（1）SO2、H2S的制備及性質的實驗設計
【投影】請設計一套實驗裝置生成SO2并證明SO2有氧化性、還原性和漂白性。
【提問】

討論、設計實驗方案。
思考并回答：
①氣體發生裝置、證明還原性的裝置、證明漂白性的裝置、證明氧化性的裝置、尾氣吸收裝置。
②使SO2與H2S反應。
2H2S+SO2=3S↓+2H2O，將觀察到有淡黃色固體物質生成。
③
Na2SO3+H2SO4=Na2SO4+SO2↑+H2O
FeS+H2SO4=FeSO4+H2S↑
④濃硫酸可將-2價S元素氧化。
⑤使SO2通過裝有溴水或酸性KMnO4溶液的洗氣瓶。溶液將褪色。
Br2+SO2+2H2O=2HBr+H2SO4
⑥使SO2氣體通過裝有品紅溶液的洗氣瓶或與濕潤的有色布條接觸，品紅溶液或布條將褪色。
⑦因SO2和H2S均污染環境，所以不能排入大氣，可用堿液吸收。
⑧充分討論后最終得出下列裝置圖：（見圖3-5）
【投影】SO2氧化性、還原性、漂白性的驗證：
【練習】將等體積的SO2和Cl2的混合氣體通入品紅溶液中，品紅溶液是否褪色？為什么？
思考、討論并解答：不褪色，原因是發生了如下反應：
SO2+Cl2+2H2O=2HCl+H2SO4
【板書】
自我總結與概括。
【板書】（2）濃硫酸性質的實驗設計
【提問】濃硫酸有哪些特殊性質？舉例說明。（要求學生口述有關反應的化學方程式）。
回憶、再現濃硫酸的特殊性質。思考并回答：①吸水性――濃硫酸在空氣中放置吸水而增重，濃硫酸可做氣體干燥劑。②脫水性――濃硫酸使蔗糖炭化，濃硫酸使乙醇脫水轉化為乙烯。③強氧化性――濃硫酸與金屬Cu、非金屬C等反應。
【投影】請設計一套實驗裝置圖，用來演示濃硫酸與木炭共熱的反應及檢驗其生成的產物。
【提問】
①寫出濃硫酸與木炭反應的化學方程式。選擇該反應的發生裝置。
討論、設計實驗方案。
討論、思考并確定：

2SO2↑+CO2↑+2H2O，依據反應物的狀態和反應條件，選擇如下實驗裝置：
②應先檢驗何種產物？選擇實驗裝置。
②應先檢驗水，選擇如下裝置：
③填寫下面的表格：
③
據上確定如何檢驗SO2和CO2，設計出實驗裝置圖并說明實驗現象及得出的結論。
回答：A中的品紅溶液褪色，則證明了SO2的存在。B中的酸性KMnO4溶液或溴水用于吸收SO2，實驗過程中顏色將變淺。C中的品紅溶液用于證實SO2是否除凈。當C中品紅不褪色，D中石灰水變渾則證明了CO2的存在。
師生共同歸納后得出下面的實驗裝置圖：
【投影】濃硫酸與木炭反應的實驗設計：
【板書】
【提問】含硫元素的陰離子主要有哪些？
思考、回憶并歸納出：S2-、SO32-、S2O32-、SO42-。
【板書】
（3）S2-、SO32-、S2O32-、SO42-檢驗的實驗設計
【提問】各種離子應如何檢驗？將檢驗方案填寫在下面的表格內：
討論、總結出各種離子的檢驗方案，與教師共同完成表格。
【投影】幾種含硫離子的檢驗：
【提問】在某溶液中加入BaCl2溶液和稀硝酸，有白色沉淀產生，原溶液中一定有SO42-離子嗎？為什么？
思考討論在教師的引導下得出：原溶液中不一定含SO42-，原因是：
①Ag+與BaCl2產生的AgCl同樣不溶于稀硝酸。
②若原溶液中含有SO32-，則加入BaCl2溶液時產生BaSO3沉淀，該沉淀遇稀硝酸會被氧化成BaSO4，仍然是白色沉淀。
【過渡】由此可見Ag+、SO32-對SO42-的檢驗有干擾。那么，應如何正確的檢驗SO42-呢？
討論、發表不同見解。最終得出正確的檢驗方法是：先加稀鹽酸排除Ag+、SO32-離子的干擾，再加BaCl2溶液，有白色沉淀產生，則證明原溶液含SO42-。
理解與記憶。
【板書】S2-、SO32-、S2O32-離子的檢驗用酸，SO42-離子的檢驗是先加稀鹽酸，再加BaCl2溶液。
【投影】硫和氯是同周期的主族元素，通過哪些事實可以證明氯的非金屬性強于硫？請從原子結構的角度給予解釋。
討論、回憶歸納得出：
①Cl2與Fe、Cu反應生成FeCl3、CuCl2，而S與Fe、Cu反應生成FeS、Cu2S。
②Cl2與H2見光可發生爆炸性反應，H2可在Cl2中燃燒，H2與Cl2
極易化合，HCl很穩定。S蒸氣與H2加熱才化合，H2S不穩定。
③Cl2通入H2S溶液中會置換出S，即Cl2+H2S=S↓+2HCl。
④酸性：HClO4（最強酸）＞H2SO4（強酸）。
引導學生從原子結構的角度解釋這些事實并得出下面結論：
【板書】原子結構→非金屬性（氧化性）：Cl＞S

教學過程設計
教師活動
【引言】
我們已經知道鹽溶液不一定是中性溶液，其原因是由于鹽類的水解。本次課的內容是復習水解實質、規律及相關知識在解決實際問題中的應用。
學生活動
回憶思考有關鹽類水解的概念及其規律。
【投影演示】
（1）少量CH3COONa固體投入盛有無水乙醇的培養皿，滴加幾滴酚酞，然后再加入少量水。（2）少量鎂粉投入盛有NH4Cl水溶液的培養皿。
【提問】
請結合兩個實驗現象，分析、解釋其本質原因，并寫出有關離子方程式。
觀察實驗，記錄現象：
（1）開始酚酞不變色，加水后變紅色；
（2）有氣泡產生。
討論分析現象得出：
實驗（1）CH3COO-與水電離出的H+結合生成CH3COOH，而使水的電離平衡向右移動，溶液顯堿性。因此鹽類水解，水也是必要的反應物之一。
CH3COO-+H2O
CH3COOH+
實驗（2）NH4+水解，使溶液顯酸性，鎂與水解產生的氫離子發生置換反應生成氫氣。
NH4+H2ONH3?H2O+H+
Mg+2H+=Mg2++H2↑
由于水解平衡的正向移動，產生的氣體中除氫氣可能也有氨氣。
