Section A 1a4 教学设计及解析 课时目标 1学会就某一问题进行辩论。 2了解一些动物名称及习性。 课程导入 人就是一种高级的动物，爱护动物其实就是爱护自己。“To help animals is helping people.”帮助动物就是帮助人们，如果你们“Love me”，那就请大家“Love my dog”吧。 探究新知 1a Here are some words that describe animals. Write these words in the boxes below. Then write other words you know.这里有一些描述动物的词。把它们填在下面的方框里。然后写出一些你知道的别的单词。 参考答案: African elephants: enormous, grayCheetahs:spotted, fastChimpanzees: noisyKangaroos: playfulManatees: gentle, shyPolar bears:aggressive, funny 知识点1 Were trying to save the manatees.我们正在竭尽全力拯救海牛。 【讲解】try to do意思是“努力去做某事”，相当于try ones best to do。用于“做某件事有困难或需要付出巨大努力，但说话人主观上要克服困难，想方设法，尽力去做好它”的场合。如： Every student should try to study hard in order to studyin a university.为了进入大学学习，每个学生都应该努力学习。 【例1】汉译英 我正在尽力成为足球队的一员。 Im_ my_ to become a member of the football team. 【解答】本题考查短语“尽最大努力”的表达方法。try ones best或do onet best；根据Im要用现在进行时。答案：trying/doing，best。 提示 try doing 表示“试一试，看看某种办法是否对路”，相当于try and see if a method works。 1b Listen and the words in activity la thatVictor and Ginny use to describe the animals.听录音，把在活动1a中Victor和Ginny用来描述动物的词画上圈。 听力材料 Boy: Hey, Ginny. Whats that big, furry animal in the pond? Girl: Its a polar bear, Victor. Theyre kind of aggressive. Boy: Are they? Looks like they really love water. Girl: Uhhuh. Boy: And what do you call those big, gray things in the water? Girl: Theyre called manatees. Boy: What? Girl: Manatees. Theyre very gentle and very shy. Boy: Oh. And how about the yellow and black spotted animals in that cage? Girl: Theyre cheetahs. The cheetah is the fastest animal on earth. 参考答案 These words should be circled: aggressive, gentle, shy, furry, gray, fast, spotted 1c GROUPWORK Think of an animal that is the same as you in some ways. Write a statement about you and the animal. Read your statement without saying the name of the animal.The class guesses what kind of animal you are like.想出一种同你在某些方面相像的动物。写出关于你和这种动物的陈述。然后把你的陈述读出来，不要说出动物的名字，让同学们猜出你像什么动物。 知识点2 I am like this animal because I am strong and intelligent.我像这个动物是因为我身强体壮，很聪明。 【讲解】be like= look like= be similar to像，看起来像。如： He is like his father.他像他的父亲。 = He looks like his father. = He is similar to his father. 这里的like作介词讲，意思为“像”，like还可作动词用，表示“喜欢”，like （doing）sth.喜欢做某事。如： He likes his father very much.他很喜欢他的父亲。 Mary likes playing volleyball.玛丽喜欢打排球。 拓展归纳: dislike不喜欢 unlike不像 【例2】单项选择 （l）Look at the kites. They_birds in the sky.AlikeBlikesCare likeDlooks like （2）Lucy_Lily. Dont you know they are twins?AlikesBlikeClooks atDlooks like （3）I_basketball very much. And youre strong and_a basketball player.Alook like, look likeBlike, likeClook like, likeDlike, look like 【解答】（1）句意应理解为“他们像天空中的鸟儿”，因此答案为C。D应改为look like才是对的。（2）根据下句解释说“她们是双胞胎”，因此，应该是“看起来像”答案为D。（3）上句应是“我非常喜欢篮球”，下句中应该是“你很结实，你很像一名篮球队员”。因此答案为B。 拓展归纳： look like看起来像feel like doing sth.想要做某事would like to do sth.想要做某事 2a List en and match the words and definitions.听录音把这些单词和定义搭配起来。 听力材料 Boy: Can you tell us about the manatees, please? Man: Sure. Were trying to save them. Boy: Why? Are they endangered? Man: Yes. There used to be a lot of manatees, but now there arent very many of them. Boy: Do you know how many there are? Man: At this point, there are only about 2,500 in the U. S. In 1972, it was discovered that they were endangered. Since then, the government has passed laws to protect them. Boy: Where do they live? Man: Their favorite habit is the water under the trees in mangrove swamps. Boy: And why are they endangered? Man: Some of the swamps have become polluted. Also, there sometimes isnt enough food for all of them. As you can see, theyre large. The average manatee is about ten feet long and weighs about 1,000 pounds. They need about 100 pounds of aquatic feed a day. Boy: Aquatic feed? Man: Oh, thats underwater plants and vegetation. Thats what they eat. 参考答案: 1b 2d 3a 4c 2b Listen again and complete the chart.重新听遍录音并完成表格。 参考答案: Kind of animal: manatee Numbers:2,500 in the U. S. Habitat: Water and trees in mangrove swamps Reason why they are endangered: swamps polluted, not enough food Description: large, three meters long, weighs 1,000 pounds. 2c PAIRWORK Use the facts in the chart above to role play a conversation between a student and a zoo attendant.用上面表格中的事实来角色扮演一个学生与一位动物管理员之间的对话。 拓展归纳： measurement计量 It is（ten）metres/kilometreslong（长）/wide（宽）/deep（深）/high（高） 句型小结：主语be数词单位形容词。 知识点3 How big are manatees? 海牛有多大？ 【讲解】How big在这里询问体重。如： How big are manatees? 海牛有多大？ They are about 10 feet long and they weigh about 1,000 pounds.他们大约有10英尺长，1,000磅重。 以How组合的疑问词组有很多，如：How old（询问年龄），How often（询问频率），How long（询问动作持续的长短），How much（询问重量或价钱），How far（询问距离），How many（询问数量），How soon（询问将过多久）。 【例3】用有关how的疑问词填空。 （1）_are you?

Yes，I have.I have just had it.（说明现在我不饿了） B现在完成时表示过去已经开始，持续到现在的动作或状态，可以和表示过去某一时刻延续到现在（包括“现在”在内）的一段时间的状语连用。如： I have learned English for three years.我已经学了三年英语了。 He has had the bike for half a year.他买这辆自行车半年了。 C现在完成时可以和already, never, just, before, yet等状语连用。如： Have you ever eaten fish and chips? I have already finished my job. I havent learned the word yet 提示 for一段时间 since过去某一时间点 since表示一般过去时的时间状语从句。 提示 already“已经”，用在肯定的陈述句中； yet 也表示“已经”，用于否定句和疑问句中。 【例5】单项选择 （1）_ you _a letter to your mother yet?

Yes, she_ the party three years ago. She_a party member for 3 years.Ajoined, has beenBhas joined, has beenCwas joined, isDjoined, was 【解答】（1）做选择题时须就现在完成时的构成，意义及时间状语一一过关，找出重要信息，然后根据前后语境选准答案。答案为B。（2）正确理解have gone to，have been to和have been in，特别是它们间的差别是解决这类题的关键。答案为A。（3）第一空的时间状语是three years ago，应用一般过去时；第二空时间状语for three years，应用现在完成时，且动词用延续性动词。答案为A。 拓展归纳： 现在完成时，当时间状语是for.或since.时，谓语动词必须是延续性动词。常见的这类动词有：短暂性延续性动词buyhavediebe deadcome/gobe here/thereborrowkeepbeginbe onleavebe away（from）joinbe in/a member of 3a Read the letter to the editor and underline the reasons why the writer is opposed to zoos.读这封致编辑的信，然后把作者反对动物园的原因的句子打上下划线。 参考答案: Terrible places for animal to live . animals are kept in tiny cages . can hardly move at all. only given food once a day 知识点6 I am writing to say that I am against building a new zoo in our town.我写信的目的是要表明我反对在镇上新建一座动物园。 【讲解】against（介）逆着，反对，违反，与相反（同义词：opposite to）如：Are most people against the proposal? 大多数人反对这项提议吗？ against（介）触，碰，倚，靠。如：Putthe piano there, with its back, against the wall.把钢琴放在那里，背靠着墙。 （2）be against（doing）sth.意为“反对（做）某事”，反义词组是be for（doing）sth.意思是“赞成（做）某事”。如：All the people around the world are against cloning human beings.全世界的人民都反对克隆人类。 All of us are for peace and against war.我们都赞成和平，反对战争。 提示 play against 表示“与进行比赛”；play for 则表示“效力于”。 【例6】单项选择 Most of the people are_the war.AagainstBforCtoDon 【解答】依据题意“大多数人反对战争”。“反对”用介词against。答案为A。 知识点7 Ive visited alot ofzoos in my life，and I have never seen one I liked or one that was suitable for animalsto live in.我参观过许多动物园，至今还没看到过一座我喜欢的或是适合动物居住的动物园。 【讲解】（1）be suitable for sb.to do sth.表示“适合某人做某事”，这里suitable 是suit的形容词形式，表示“合适的”。如： This kind of bamboo is not suitable for pandas to eat.这种竹子不适合给熊猫吃。 This dress suits you very much，but unfortunately it doesntfit you.这套女装款式非常适合你，只可惜大小不合身。 （2）to live in在此处作animals的后置定语。英语中动词不定式短语作名词定语，放在后面。如： There is nothing for us to worry about.我们没有什么可以担心的。 【例7】单项选择 The information doesnt_what I was told yesterday.Afit onBfit upCfit in withDagree on 【解答】fit on穿上（看是否合适），装上；fit in/into放进去；fitin with适合，符合，一致；fit up安装；be fit for适合。答案为C。 拓展归纳： suitable是suit加上形容词字尾able构成的，表示“有能力的，适合的足以做”的意思，被修饰的名词有被动的意思。如： available可利用的 unforgetable令人难忘的 horrible可怕的 desirable值得要的 提示 suit 表“合适”之意时常易和fit 混淆。sth.suits sb.和sth.fits sb.都指“某物适合某人”，但sth.suits sb.更强调颜色或款式适合某人，而sth.fits sb. 更偏重于大小型号尺码是否合身。 知识点8 The animals are kept in tiny cages.动物被关在极小的笼子里。 【讲解】tiny（adj.）“很小的”，与little通用，两者均带有感情色彩区别： the tiny country国家小（含可爱的意思） a small country（小国家）与a large country相对应。 a small boy年龄小、身材小而可爱的孩子。 a little boy爱怜之意（不含身材矮小） tiny和little常作定语，一般不作表语。 small既作定语，也可作表语。 little有时还可表示“一点点的”，修饰不可数名词。如： There is a little milk in the bottle.瓶里有一点点（或少量）牛奶 【例8】单项选择 （A）找出与画线部分意义相同的词。 （1）Look.The tinykangaroo is very interesting.AlittleBfewCbigDsmall （B）选择最佳答案。 （2）This coatis large for me.Do you have any_ one?AlittleBsmallClargerDtiny 【解答】（1）答案为（A）。（2）答案为：（B） 3b Now read this letter to the editor.Do you agree with“Disgusted”or“Animal Friend”? Write a letter to the editor and give your opinion.现在看这封给编辑的信。你是同意Disgusted还是Animal Friend的意见呢？写一封信给编辑，谈谈你的观点。 知识点9 I was surprised to find hardly anyone there.我非常惊讶地发现在那儿几乎没有人。 【讲解】surprised在这里是过去分词作形容词。 常用词组: be surprised at sth.对某事感到惊讶 be surprised to do sth.很惊讶地做某事 in surprise惊奇地 toonessurprise使某人惊讶地。如： I was surprised at the news/to hear the news.听到这个消息我很吃惊。 surprise（v.）使惊讶（同义词amaze） surprising（adj.）惊讶的（侧重指事物本身具有的特点），如： His words surprised me.他的话使我大吃一惊。 It is surprising news.它是一个令人惊讶的消息。 【例9】用所给词的适当的形式填空。 （1）When he heardthe news, he felt very_（surprise） （2）Her mother decided to have a_party for her birthday.（surprise） 【解答】（1）答案为surprised，意为“他感到非常地吃惊”。 （2）surprise可直接作名词修饰party，因此答案为surprise，意为“惊奇晚会”。 知识点10 They provide hones for many endangered animals, and help to educatethe public about caring for them.（动物园）它们为许多濒危的动物提供了家，也有助于教育众人来关心这些动物。 【讲解】（1）provide（v.）（人）提供某事供给，供应 词组provide sb.with sth. provide sth.for sb.提供给某人某物。如： The firm provided me with a car.公司给我一辆汽车。Can you provide accommodation for thirty people? 你能为30人提供住宿吗？ provide for sb.供应某人所需。如： They worked hard to provide for their large family.他们努力工作以供养一家人。 He has a large family to provide for.他要养活一个大家庭。 （2）the public指“民众，公众”。在英语中，定冠词the后接形容词表示一类人。如： the young年轻人 the wounded受伤的人 （3）care for可作“照顾，照料，看护”的意思。如： Would you care for a cup of tea? 你要不要来杯茶？ 【例10】单项选择 She thinks only of herself. She doesnt_other people.Acare aboutBcare forCcare ofDcare to 【解答】“她只考虑自己，从不在乎其他的人”。答案A。 提示 carc作动词时的词组很多，容易混淆，在此归纳一下: care about 关心，在乎；care for 看护，照料，喜欢；care 也可作名词，take care of=look after（照顾，照看） 知识点11 I urge all of your readers to visit our wonderful zoo soon.我们竭力主张你们所有的读者赶快来参观我们的很棒的动物园。 【讲解】urge（v.）力劝、鼓励，怂恿，极力主张，强调。如：They urged us to go with them.他们怂恿我们一起去。She urged the importance of speed.她强调速度的重要性。urge（n.）强烈的欲望、冲动，urgent（adj.）紧急的。如： He has an urge to travel.他有去旅行的强烈欲望。 词组: urge sth.on/upon sb.极力推荐或力陈某事物urge sb.on sth.鼓励某人做某事urge against极力反对 【例11】单项选择 （l）He urged his pupils_the importance of hard words.AforBatCtoDon （2） Some parents expect their children to study all day.
