教学建议
教学教法：
本单元日常交际用语的重点是让学生掌握向他人提出建议和忠告的方式。第45课第二部分已给出的短语和句型足以满足学生在实际阅读及写作中的需要，因此教师应从熟练运用的角度对学生进行指导和要求。例如清楚区分每种句型和表达的准确含义及用法，搭配。可以要求学生做适当的句式转换练习，造句练习等。2.本单元阅读文章为有关冬眠的科普短文。从文章所用语言来看，较为平易，浅显，然而其中也有因阐明事理的需要而出现的长句，难句，教师要对此进行专门的分析，讲解。此外，教师还可以从兴趣爱好（如养小动物）及爱护动物的角度适度扩展与课文相关的内容，来达到了解掌握科学知识并能够学以致用的目的。
词语辨析：
1.weather和climate
weather 意为“天气”，为不可数名词，不能在前面加不定冠词，如我们只能说in such fine weather , 而不能说in such a fine weather。如：
The weather has changed. 天气变了。
【注意】weather前虽不可加不定冠词，但在表示“各种各样的天气”，或“不论哪种天气”时，weather用复数。如：
She goes out in all weathers.
weather 指某特定地区在一定时间的气象情况。
climate 指一般比较长的时间，如一季的天气状况。
A drier climate would be good for her health.气候干燥的地区会对他的健康有益。
2.cause 和reason
cause 用作及物动词，意为“引起、使产生、给……带来。”例如：
What caused the accident?
是什么引起这个事故的？
cause 用作名词，意为“原因，理由”。例如：
Carelessness is the usual cause of fire.
造成火灾的原因通常是不谨慎。
cause 是造成一种事实或现象的“原因”，
Heat is the cause of the expansion of matter.热是物体膨胀的原因。
reason 是说明一种看法或行为的“理由”。例如：
You must tell him the reason why you won’t accept his offer.
你必须告诉他你为何拒绝他的提议。
3.deep, deeply
deep可作形容词，表示“深的”，又可作副词，表示“深深地”。这里是具体意义的“深”。
The river is very deep here. (deep是形容词)
He pushed his stick deep into the mud. (deep是副词)
在一些固定的搭配中使用deep, 尤其在介词词组前。如：
be deep in debt 债台高筑
be deep in thought 深入沉思
do sth. deep into the night 一直做到深夜
deeply是deep后缀-ly构成副词, 使用时一般具有抽象含义，意为“深深地，深厚地，深切地”。如：
We are deeply grateful for your help. 我们非常感谢你的帮助。
4.fly away 与fly off
1）它们俩都可表示“匆匆离去（飞去）”之意，但有一些差别。fly away距离较远，而fly off指距离较近。
Then they flew away into their hiding place.
后来他们窜回到他们躲藏的地方去了。
When he was driving very fast, one of the wheels of his wagon flew off.
他正把车开得飞快，一只轮子突然脱落了。
2）away是副词，off既可作副词，也可作介词。off后可跟宾语，away后则不可。如：
The bird shook its tail and flew away. 那只鸟摇着尾巴飞走了。
【注意】把动词keep, run, walk, move等后面加上away或off, 其区别与上述所谈类似。如：
What kept you away last Sunday? 上星期日你为什么没来？
Keep off the grass! 勿踏草地！

(8)Some animals, including some bears, only half-hibernate.难句解析： 1．They go to sleep in all kinds of places.它们到各种各样的地方去睡觉。 go to sleep，fall asleep与sleep，这三个词（组）都有“睡着”之意。go to sleep意思是“睡着，去睡觉”，fall asleep意思是“睡着了，酣睡”，它们都表瞬间动作，如表持续性动作或延续性状态，要用动词sleep。e.g. ①I found it very difficult to go to sleep．我发现很难人睡。 ②Soon he fell asleep，for he was very tired．他很累，很快就睡着了。 ③we have slept(for) eight hours.我们已睡了八个小时。 2．They lead an active life which keeps up their normal body temperature even in very cold winter weather. 他们生活得很活跃，即使在严寒的冬天也能保持正常的体温。习惯用法 （2）keep up保持，维持，继续，e．g． ① Let s hope the sunny weather keeps up for Saturday s tennis match. 但愿星期六网球比赛时还是这样的好天气。 ②We。Are having difficulty keeping up。our。mortgage payments．我们难以继续支付分期偿还的抵押货款。 ③If you want to be a performer，you 11 have to keep up your piano．如果你真想成为演奏家，就得坚持练习钢琴． 3.Then it as no choice but to lie down and sleep．于是，别无选择，它们只好躺下睡觉。 have no choice but to do表“别无选择”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，我还有别的选择吗？表示“别无选择只好做……”之意，除了可用 have no choice but to do…来表达外，还可用下列固定搭配： （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．她别无它法，只有哭。 （3）can’t but do…，e．g． I could not but admit that he was right and。I was wrong．我不得不承认他对了，我错了。疑难点拨： 1.Hibernation is more than sleep．冬眠不仅仅是睡眠。 句中的more than相当于 not only。意为“不仅仅”。e．g． He is。more a teacher．He is a good friend of mine。他不只是老师，还是我的益友。 2．People who find hibernating animals asleep often think that they are dead.．人们看到处于冬眠状态的动物，常常以为它们死了。 这是一个复合句。 （l）who－clause是定语从句修饰people，that－clause是宾语从句作think的宾语。 （2）asleep是表语形容词，在句中一般只作表语，宾补，或后置定语，这样的形容词还有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，这也不会使它动一动或醒过来。 这个句子可改写成：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. 用那种方式冬眠，动物可以睡过整过冬天。 句中的 hibernating in that way是现在分词短语在句中作状语，相当于as they hibernate in that way。 5．We have seen that hibernating animal reduces movements to far below the ordinary level.． 冬眠动物的'活动量减少到远远低于一般水平。 (1)句中的 far below意为“远远低于，比……低得多”。e．g． In winter the temperature of Harbin is far below that of Wuhan． 冬天哈尔滨的气温比武汉的低得多。 （2）句中的reduce．．to作“减少，使处于……状态”解。e．g． ① The house was reduced to ashes by the big fire.那场大火把屋子化为灰烬。 ②The man was reduced to begging for food．那男人沦落到讨饭的地步。
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.

高考难题解析：
1.Most animals have little connection with _______ animals _____ different kind unless they kill them for food.
A. the; a B. 不填; a C. the; the D. 不填; the
答案：B 通过率：26％
试题分析：本题测试的是冠词在日常生活情景中的使用能力。此题最大的难点在于：冠词的语法规则无法完成冠词使用能力的培养。完成此题的“诀窍”在于具备较强的阅读理解能力；只有读懂此题的内容，才能作出比较准确的翻译。此题可以这样翻译：“大多数动物之间没有什么关系，除非它们（即：某一种动物）以另一种动物为食。”“大多数动物”自然是“不加定冠词的多数名词的泛指”，而“某一种动物”或“另一种动物”则自然是“加不定冠词的单数名词”。只有这样，才可能作出正确的选择。
2._______ production up by 60%, the company has had another excellent year .
A. As B. For C. With D. Through
答案：C 通过率：42％
试题分析：本题测试的是介词在日常生活情景中的使用能力。此题最大的难点在于：A．As B．For C．With D．Through少四个选项，就个体词义而言，都表示“原因”，但是在此题的具体情景中，只有C．With无论在句型上（with + 名词noun + 介词prep．／或形容词adj. ）还是内容上（具有“伴随时间接原因”的含义）都是最佳选项。这个句子可以翻译成：“随着生产量的提高，到达60％，该公司又经历了一个业绩大好的年头。”
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 通过率：34％
试题分析：本题测试的是动词不定式在日常生活情景中的使用能力。完成此题的关键在于：对于know what to expect/where to go/who to see /when to begin /why to do so/how to do it 这类语句的熟练掌握。当然，要做到这一点，大量的口笔语实践是必不可少的。
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 通过率：48
试题分析：本题测试的是动词时态在日常生活情景中的使用能力。完成此题的关键在于：不要过分依赖有关时态教学的语法规则。首先必须在词义上理解清楚。只要将这个对话翻译成汉语，就能够找到正确选项：
------你今天这么样啊？
------哎呀，好久没有像今无这样难受了。
这句译文使人想起“（I）haven’t seen you for ages．”（“好久没有见到你了。”）
这两句话使用的不都是现在完成时吗？
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 通过率：46％
试题分析：本题测试的是连词与连词短语的使用能力。完成此题不仅要能够熟练使用A．as long as B．while C．If D．even though等四个词语，而且还要具备“阅读熟词新义”的能力。因为这个句子虽然不长，但是却包含live up to…（配得上…，be home to…（是…的家园）等等“熟词新义”；没有“阅读熟词新义”的能力必然会有失误。此外，如果，考生对于类似“中国人口占世界五分之一，世贸组织没有中国，该组织本身就会名不副实。”的说法十分熟悉的话，也有助于选好此题的最佳选项社（条件从句）。
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 通过率：26％
试题分析：本题测试的是在特定的上下文中使用过去分词的能力。要完成此题必须能够熟练而准确地确定全句各个词语的逻辑关系（主体与客体关系，主动与被动关系，语句层次关系），从而翻译成比较准确的汉语：“经理们讨论了这个计划，大家都希望明年能够看到这个计划能够成为现实（被付诸实施）。”既然是“被付诸实施”，当然要选“被动语态”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 通过率：26％
试题分析：本题测试的是在特定的上下文中代词的习惯用法。要完成此题必须具备较丰富的英语使用实践经验，否则，一般“泛泛”的语法规则是无法指导考生顺利完成此题的。
