　　I suggest you (should).　Shall we. . . ?

　　Let's... . 　　　　　　　　What/How about. . . ?

　　Why not. . . ? 　　　　　　Why don't we / you. . . ?

　　教學(xué)建議

　　教學(xué)教法：

　　本單元日常交際用語的重點是讓學(xué)生掌握向他人提出建議和忠告的方式。第45課第二部分已給出的短語和句型足以滿足學(xué)生在實際閱讀及寫作中的需要，因此教師應(yīng)從熟練運用的角度對學(xué)生進行指導(dǎo)和要求。例如清楚區(qū)分每種句型和表達的準確含義及用法，搭配�？梢砸�求學(xué)生做適當?shù)木涫睫D(zhuǎn)換練習，造句練習等。

　　2.本單元閱讀文章為有關(guān)冬眠的科普短文。從文章所用語言來看，較為平易，淺顯，然而其中也有因闡明事理的需要而出現(xiàn)的長句，難句，教師要對此進行專門的分析，講解。此外，教師還可以從興趣愛好(如養(yǎng)小動物)及愛護動物的角度適度擴展與課文相關(guān)的內(nèi)容，來達到了解掌握科學(xué)知識并能夠?qū)W以致用的目的。

　　詞語辨析：

　　1.weather和climate

　　weather 意為“天氣”，為不可數(shù)名詞，不能在前面加不定冠詞，如我們只能說in such fine weather , 而不能說in such a fine weather。如：

　　The weather has changed. 天氣變了。

　　【注意】weather前雖不可加不定冠詞，但在表示“各種各樣的天氣”，或“不論哪種天氣”時，weather用復(fù)數(shù)。如：

　　She goes out in all weathers.

　　weather 指某特定地區(qū)在一定時間的氣象情況。

　　climate 指一般比較長的時間，如一季的天氣狀況。

　　A drier climate would be good for her health.氣候干燥的地區(qū)會對他的健康有益。

　　2.cause 和reason

　　cause 用作及物動詞，意為“引起、使產(chǎn)生、給……帶來。”例如：

　　What caused the accident?

　　是什么引起這個事故的?

　　cause 用作名詞，意為“原因，理由”。例如：

　　Carelessness is the usual cause of fire.

　　造成火災(zāi)的原因通常是不謹慎。

　　cause 是造成一種事實或現(xiàn)象的“原因”，

　　Heat is the cause of the expansion of matter.熱是物體膨脹的原因。

　　reason 是說明一種看法或行為的“理由”。例如：

　　You must tell him the reason why you won’t accept his offer.

　　你必須告訴他你為何拒絕他的提議。

　　3.deep, deeply

　　deep可作形容詞，表示“深的”，又可作副詞，表示“深深地”。這里是具體意義的“深”。

　　The river is very deep here. (deep是形容詞)

　　He pushed his stick deep into the mud. (deep是副詞)

　　在一些固定的搭配中使用deep, 尤其在介詞詞組前。如：

　　be deep in debt 債臺高筑

　　be deep in thought 深入沉思

　　do sth. deep into the night 一直做到深夜

　　deeply是deep后綴-ly構(gòu)成副詞, 使用時一般具有抽象含義，意為“深深地，深厚地，深切地”。如：

　　We are deeply grateful for your help. 我們非常感謝你的幫助。

　　4.fly away 與fly off

　　1)它們倆都可表示“匆匆離去(飛去)”之意，但有一些差別。fly away距離較遠，而fly off指距離較近。

　　Then they flew away into their hiding place.

　　后來他們竄回到他們躲藏的地方去了。

　　When he was driving very fast, one of the wheels of his wagon flew off.

　　他正把車開得飛快，一只輪子突然脫落了。

　　2)away是副詞，off既可作副詞，也可作介詞。off后可跟賓語，away后則不可。如：

　　The bird shook its tail and flew away. 那只鳥搖著尾巴飛走了。

　　【注意】把動詞keep, run, walk, move等后面加上away或off, 其區(qū)別與上述所談類似。如：

　　What kept you away last Sunday? 上星期日你為什么沒來?

　　Keep off the grass! 勿踏草地!

　　本單元重點句型

　　(1)Hibernation is more than sleep.

　　(2)People who find hibernating animals asleep often think that they are dead.

　　(3)You can touch it, or even pull its tail, without causing it to move or wake up.

　　(4)Hibernating in that way, the animals can sleep all through the winter.

　　(5) The second is connected with the main use the body makes of food—to supply the energy for movements.

　　(6) We have seen that hibernating animal reduces movements to far below the ordinary 　　level.

　　(7) The animal hardly makes any movement, hardly uses any energy, and hardly needs any food.

　　(8)Some animals, including some bears, only half-hibernate.

　　難句解析：

　　1.They go to sleep in all kinds of places.它們到各種各樣的地方去睡覺。

　　go to sleep，fall asleep與sleep，這三個詞(組)都有“睡著”之意。go to sleep意思是“睡著，去睡覺”，fall asleep意思是“睡著了，酣睡”，它們都表瞬間動作，如表持續(xù)性動作或延續(xù)性狀態(tài)，要用動詞sleep。e.g.

　�、買 found it very difficult to go to sleep.我發(fā)現(xiàn)很難人睡。

　�、赟oon he fell asleep，for he was very tired.他很累，很快就睡著了。

　�、踳e have slept(for) eight hours.我們已睡了八個小時。

　　2.They lead an active life which keeps up their normal body temperature even in very cold winter weather.

　　他們生活得很活躍，即使在嚴寒的冬天也能保持正常的體溫。

　　習慣用法

　　(2)keep up保持，維持，繼續(xù)，e.g.

　�、� Let s hope the sunny weather keeps up for Saturday s tennis match.

　　但愿星期六網(wǎng)球比賽時還是這樣的好天氣。

　�、赪e。Are having difficulty keeping up。our。mortgage payments.我們難以繼續(xù)支付分期償還的抵押貨款。

　�、跧f you want to be a performer，you 11 have to keep up your piano.如果你真想成為演奏家，就得堅持練習鋼琴.

　　3.Then it as no choice but to lie down and sleep.于是，別無選擇，它們只好躺下睡覺。

　　have no choice but to do表“別無選擇”之意。e.g.

　　Have I any choice but to do as you tell me? 除了按你吩咐的去做外，我還有別的選擇嗎?

　　表示“別無選擇只好做……”之意，除了可用 have no choice but to do…來表達外，還可用下列固定搭配：

　　(l)can do nothing but do/can not do anything but do，e.g.

　　I can do nothing but accept his demand.我只好接受他的要求。

　　(2)there is nothing left to do but do…，e.g.

　　There was nothing left for her to do but cry.她別無它法，只有哭。

　　(3)can’t but do…，e.g.

　　I could not but admit that he was right and。I was wrong.我不得不承認他對了，我錯了。

　　疑難點撥：

　　1.Hibernation is more than sleep.冬眠不僅僅是睡眠。

　　句中的more than相當于 not only。意為“不僅僅”。e.g.

　　He is。more a teacher.He is a good friend of mine。他不只是老師，還是我的益友。

　　2.People who find hibernating animals asleep often think that they are dead..人們看到處于冬眠狀態(tài)的動物，常常以為它們死了。

　　這是一個復(fù)合句。

　　(l)who-clause是定語從句修飾people，that-clause是賓語從句作think的賓語。

　　(2)asleep是表語形容詞，在句中一般只作表語，賓補，或后置定語，這樣的形容詞還有alive，alike，alone，awake等。

　　3.You can touch it, or even pull its tail without causing it to move or wake up. 你可以摸它，甚至可以拉它的尾巴，這也不會使它動一動或醒過來。

　　這個句子可改寫成：Even if you touch it or pull its tail，you can’t cause it move or wake up.

　　4. Hibernating in that way, the animal can sleep all through the winter.

　　用那種方式冬眠，動物可以睡過整過冬天。

　　句中的 hibernating in that way是現(xiàn)在分詞短語在句中作狀語，相當于as they hibernate in that way。

　　5.We have seen that hibernating animal reduces movements to far below the ordinary level..

　　冬眠動物的活動量減少到遠遠低于一般水平。

　　(1)句中的 far below意為“遠遠低于，比……低得多”。e.g.

　　In winter the temperature of Harbin is far below that of Wuhan.

　　冬天哈爾濱的氣溫比武漢的低得多。

　　(2)句中的reduce..to作“減少，使處于……狀態(tài)”解。e.g.

　�、� The house was reduced to ashes by the big fire.那場大火把屋子化為灰燼。

　�、赥he man was reduced to begging for food.那男人淪落到討飯的地步。

　　Step4:Fill in blanks.

　　1. They go to sleep in all kinds of places. Red squirrels disappear inside trees, bears use caves, frogs go deep under the mud, and many other animals dig holes in the earth .A good many animals sleep under the snow. There is a lot of air in loose snow, and this helps to keep the cold out.

　　2. Hibernation is more than sleep. It is a very deep sleep.the animal’s temperature drops to just over zero centigrade, and its heart beats very slowly.People who find hibernating animals asleep often think that they are dead; the body feels very cold, and the animal may breathe only once every five minutes. A hibernating animal cannot feel any pain. You can touch it , or even pull its tail, without causing it to move or wake up.

　　3.Hibernating in that way, the animal can sleep all through the winter. You might wonder how it manages to live withut eating for so many months . The answer lies in two facts. The first is that it has stored supplies of fat in its body during the summer and autumn. The second is conneted with the main use the body makes of food----- to supply the energy for movement. We have seen that the hibernating animal reduces movement to far below the ordinary level. Even the movements of the heart and lungs are greatly reduced.The animal hardly makes any movement,hardly uses any energy, and hardly needs any food.

　　A. the; a　　B. 不填; a　　C. the; the　　D. 不填; the

　　答案：B 通過率：26%

　　試題分析：本題測試的是冠詞在日常生活情景中的使用能力。此題最大的難點在于：冠詞的語法規(guī)則無法完成冠詞使用能力的培養(yǎng)。完成此題的“訣竅”在于具備較強的閱讀理解能力;只有讀懂此題的內(nèi)容，才能作出比較準確的翻譯。此題可以這樣翻譯：“大多數(shù)動物之間沒有什么關(guān)系，除非它們(即：某一種動物)以另一種動物為食。”“大多數(shù)動物”自然是“不加定冠詞的多數(shù)名詞的泛指”，而“某一種動物”或“另一種動物”則自然是“加不定冠詞的單數(shù)名詞”。只有這樣，才可能作出正確的選擇。

　　2._______ production up by 60%, the company has had another excellent year .

　　A. As　　B. For　　C. With　　D. Through

　　答案：C 通過率：42%

　　試題分析：本題測試的是介詞在日常生活情景中的使用能力。此題最大的難點在于：A.As B.For C.With D.Through少四個選項，就個體詞義而言，都表示“原因”，但是在此題的具體情景中，只有C.With無論在句型上(with + 名詞noun + 介詞prep./或形容詞adj. )還是內(nèi)容上(具有“伴隨時間接原因”的含義)都是最佳選項。這個句子可以翻譯成：“隨著生產(chǎn)量的提高，到達60%，該公司又經(jīng)歷了一個業(yè)績大好的年頭。”

　　3.I’ve worked with children before, so I know what ______ in my new job.

　　A. expected　　B. to expect　　C. to be expecting　　D. expects

　　答案：B 通過率：34%

　　試題分析：本題測試的是動詞不定式在日常生活情景中的使用能力。完成此題的關(guān)鍵在于：對于know what to expect/where to go/who to see /when to begin /why to do so/how to do it 這類語句的熟練掌握。當然，要做到這一點，大量的口筆語實踐是必不可少的。

　　4.------- How are you today ?

　　------- Oh, I ______ as ill as I do now for a very long time .

　　A. didn’t feel　　　　B. wasn’t feeling

　　C. don’t feel　　　　　D. haven’t felt

　　答案：D 通過率：48

　　試題分析：本題測試的是動詞時態(tài)在日常生活情景中的使用能力。完成此題的關(guān)鍵在于：不要過分依賴有關(guān)時態(tài)教學(xué)的語法規(guī)則。首先必須在詞義上理解清楚。只要將這個對話翻譯成漢語，就能夠找到正確選項：

　　------你今天這么樣啊?

　　------哎呀，好久沒有像今無這樣難受了。

　　這句譯文使人想起“(I)haven’t seen you for ages.”(“好久沒有見到你了。”)

　　這兩句話使用的不都是現(xiàn)在完成時嗎?

　　5.The WTO cannot live up to its name _____ it does not include a country that is home to one fifth of mankind.

　　A. as long as　　B. while　　C. if　　D. even though

　　答案：C 通過率：46%

　　試題分析：本題測試的是連詞與連詞短語的使用能力。完成此題不僅要能夠熟練使用A.as long as B.while C.If D.even though等四個詞語，而且還要具備“閱讀熟詞新義”的能力。因為這個句子雖然不長，但是卻包含live up to…(配得上…，be home to…(是…的家園)等等“熟詞新義”;沒有“閱讀熟詞新義”的能力必然會有失誤。此外，如果，考生對于類似“中國人口占世界五分之一，世貿(mào)組織沒有中國，該組織本身就會名不副實。”的說法十分熟悉的話，也有助于選好此題的最佳選項社(條件從句)。

　　6.The managers discussed the plan that they would like to see _______ the next year.

　　A. carry out　　B. carrying out　　C. carried out　　D. to carry out

　　答案：C 通過率：26%

　　試題分析：本題測試的是在特定的上下文中使用過去分詞的能力。要完成此題必須能夠熟練而準確地確定全句各個詞語的邏輯關(guān)系(主體與客體關(guān)系，主動與被動關(guān)系，語句層次關(guān)系)，從而翻譯成比較準確的漢語：“經(jīng)理們討論了這個計劃，大家都希望明年能夠看到這個計劃能夠成為現(xiàn)實(被付諸實施)。”既然是“被付諸實施”，當然要選“被動語態(tài)”的 C. carried out.

　　7.--------Why don’t we take a little break ?

　　-------- Didn’t we just have ______ ?

　　A. it　　B. that　　C. one　　D. this

　　答案：C 通過率：26%

　　試題分析：本題測試的是在特定的上下文中代詞的習慣用法。要完成此題必須具備較豐富的英語使用實踐經(jīng)驗，否則，一般“泛泛”的語法規(guī)則是無法指導(dǎo)考生順利完成此題的。
