教材内容分析

  本单元是围绕"Water sports"这一中心话题,结合现在完成时态来开展教学活动的。我们要能运用所学知识来谈论"运动",特别是一些与生活密切相关的运动项目。本单元进一步讲述了现在完成时态以及常与之连用的一些副词,通过对话将现在完成时态与一般过去时态进行了比较,使我们搞清了两种时态的差异和所强调的语法点,以及他们所需时间状语的范围。进而使学生对现在完成时态的第一种用法,表示过去发生或已经完成的动作对现在造成的影响或结果的认识更加清晰。本单元的写作训练是an interview about Li Lida who first tried to cross the Qiongzhou Channel in June, 2000。

本单元重点例句及相关知识的讲解

1.What's the surfing like today? 今天冲浪怎么样?

  surf作名词,意为"拍岸之浪,拍岸浪花";作动词用,意为"冲浪,作冲浪运动"。surfing是surf的动名词形式,surfer意为"冲浪者,冲浪运动员"。surfing是一项水上运动,水上运动的项目还有water-skiing滑水,water polo水球,dive跳水,Swim游泳。

2.Have you ever been to Hawaii? 你去过夏威夷吗?

  have been to. . .意思是"到过,去过",表示曾到过某地,但此时人已不在那儿了。而have gone to…意思是"去了某地",现在人可能在去的途中或已在那个地方了,而不在说话人处。例如:

  (1)Have you ever been to Hong Kong? 你曾经去过香港吗?

  (2)Jim has gone to England. 吉姆去英国了。

  (3)Where is Lily? Has she gone to the library? 莉莉在哪儿?她去图书馆了吗?

3.The beaches there are better than the ones here 中的the ones如何理解和使用?

  这里的ones代表前面出现beaches。one用于表示前面同名称的一类事物。ones表示复数概念。例如:

  -Have you a watch? -Yes, I have a good one.

  一你有表吗?一有,我有一块好表。

  -Have you got any pens? -Yes, I have got many good ones.

  一你有钢笔吗?一有,我有许多好钢笔。

  注意:在用one(ones)作代词时,有几点要慎重:

  ①序数词不能用one代替,伴有基数词的名词可用one,ones代替。例如:

  As we have finished the first chapter, now we'll read the second.

  我们读完了第一章,现在读第二章了。

  (不能将 the second改为 one)

  He has two red pencils and two blue ones.

  他有两支红铅笔和两支蓝铅笔。

  ②it(them)和one(ones)同是作代词,代替前面出现的事,但用法不同。

  让用于同名称的同样事物;one用于同名称的另一样东西。例如:

  -Have you still the radio set? -No. I have sold it.

  一你有收音机吗?一没有,我把它卖了。

  (这里的订是指前面的the radio set,它们是同一个无线电收音机。)

  -Is this fountain pen yours? -No, it is my sister's. Mine is the one on the table.

  一这支自来水钢笔是你的吗?一不,它是我姐姐的。我的是桌上那一支。

  (这里的one不是前面的那支fountain pen,它们不是同一支自来水钢笔。)

  -Do you want the watch? -Yes, I want it.

  一你要买那块表吗?一想买那块表。

  (同一块表,it即:the watch)

  -What are pandas like? -I've never seen one, so I don't know what they are like.

  一熊猫是什么样的?一我从来没见到过,所以不知道熊猫是什么样子。

  (one这里泛指同类事物中的一样东西)

4.I don't know how to surf. 我不知道怎样冲浪。

  how to surf是"疑问词 + 动词不定式"作宾语。英语中,"疑问词 +动词不定式"可作一些及物动词的宾语,疑问词可以是what,which,who,whose等疑问代词,也可以是when,where,how等疑问副词。可以用此结构作宾语的动词有:know,decide,find out,tell,forget,remember,see,understand等。这类简单句往往是由(含特殊疑问句变成的宾语从句的)复合句转化改写而成。例如:

  (1)She didn't know which blouse to buy. ( = She didn't know which blouse she should buy.) 她不知道该买哪件衬衫。

  (2)I'm thinking about what to say. ( = I'm thinking about what I should say. ) 我在考虑说什么。

5.Now it is enjoyed by people all over the world. 现在全世界的人都喜欢这项运动。

  is enjoyed是被动语态,by people all over the world 被全世界的人。这一句也可改写成: People all over the world enjoy it now.

6.It's neither too hot nor too cold all the year round. 全年天气既不太冷也不太热。

  neither… nor… 既不……也不……,它们可以用来连接相同的两个句子成分或词类。如果连接的是主语,则谓语与第二个主语保持一致。

  例:(1) He isn't a student. I'm not a student.

      Neither he nor I am a student.

    (2) He doesn't speak French. He doesn't speak Japanese.

      He speaks neither French nor Japanese.

  Neither…nor的完全肯定形式是:both…and或not only…but also。

  但both…and如连接主语,则谓语动词用复数,not only…but also与第二个主语保持一致。

  例:He likes singing. I like singing, too.

    Both he and I like singing. ( = Not only he but also I like singing. )

7. Li Lida, a 12-year-old schoolboy first tried to cross the Qiongzhou Channel in June, 2000.

  在2000年6月,一个12岁的男生李立达第一次试着横渡琼州海峡。

  (1)21-year-old在这里可以看作是一个合成词,作形容词用,用来修饰schoolboy。在英语中,"数字+量词"构成的复合形容词,中间要加连字符号,量词用单数形式。

  例如:100-metre race 一百米赛跑。

     two-month holiday两个月的假期。

  试比较:The boy is five years old.

      He s a five-year-old boy.

  (2)cross为动词,是"越过、穿过"的意思。意思相近的词有:through(prep).穿过,指从……(内部或空间)中穿行,across(prep).横过,指从物体的表面由这边到另一边。另外,through可作副词用。

  cross与across含义基本相同,但cross是动词。over也可表示"横过;通过",着重强调越过某物,从高空中越过。

  例:(1)Jack was through with the English test.

      杰克通过了这次英语测试。

    (2)The old lady crossed the street carefully and slowly.

      那老妇人慢慢地、小心地走过街去。

    (3)The ship passed through the bridge.

      轮船过了桥。(从桥下穿过)

    (4)The boy climbed over the wall to get his ball.

      那男孩爬过墙去取球。

    (5)The blind man walked across the street slowly.

      那盲人慢慢地走过街道。

8.His teacher, Mr Feng, spoke highly of his students 中的speak highly of ?

  这里的speak highly of是指"高度评价","赞扬"的意思。例如:

  The teachers present all spoke highly of his spirits.

  在场的老师都称赞他的精神。

  We should speak highly of his saving the girl in the cold water against the risk of his life.

  他冒着生命危险,在寒冷的水中救出这个女孩子,应该受到赞颂。

  He was spoken highly of by the girl's parents.

  他受到了女孩子父母的赞扬。

  有关speak的一些词组:

  speak ill of 说……坏话

  speak for 充当……代言人

  speak for oneself 为自己辩护

  speak sb fair 对某人彬彬有礼说话

  to speak of 值得一提(常用于否定句中)

9.He is not only the pride of our school but also the pride of all the people in Hainan.

  他不仅是我们学校的骄傲,也是海南全体人民的骄傲。

  not only…but also意思是"不仅……而且",应连接相同的语法成分。当连接主语时,谓语动词采用就近原则,即随后面的主语而定。例如:

  (l)Not only you but also your father is coming. 不但你,而且你父亲也要来。(连接主语)

  (2)Jane is not only beautiful but also kind. 珍妮不但漂亮,而且人非常好。(连接表语)

  (3)He plays not only the piano but also the violin. 他不仅弹钢琴,还拉小提琴。(连接宾诺)

  (4)They not only sing but also dance. 他们不但唱还跳。(连接谓语)

10.no matter +what/who/which/when/where /how

  无论……。No matter这个词组可以用来接两个分句,不能只用于一个分句。另外,no   matter后面用的是现在时,其含义却是将来。

  No matter what you say, I won't believe you.

  无论你说什么,我都不会相信你。(解释是没有用的)

  No matter who telephones, say I'm out. 无论谁打电话来,都说我出去了。

  No matter when you come, you'll be more than welcome.

  无论你什么时候来,你都会受到热烈地欢迎。

  No matter how hard you try, you'll never lose your English accent.

  无论你怎么努力,你都不会改掉你的英文口音。

11. none,neither

  none一般指三者或三者以上"都不",是代词all的反义词。当谈到两个人或两件事的时候,不用non,而用nether,意思是"两者都不",是代词both的反义词。none和none of作主语时,谓语动词即可以用单数形式,也可以用复数形式。当表示一个人或物"都不"时,一般用单数形式;当表示所有的人或物"都不"时,一般用复数形式。当它在非正式的文体中更常用复数形式。neither,neither of作主语时,谓语动词一般用单数形式。但如果是neither…nor…"既不……也不;两者都不"作主语时,谓语动词根据nor后面的主语而定(也称为邻近原则)。

  None of her students are/is here.她的学生中没有一个在这里。

  None of those buses go to Tianjin.

  那些公共汽车没有一辆是开到天津去的。

  Neither of her parents helps her. 她的父母都不帮助她。

  Neither of the two boys is right. 这两个男孩没一个对。

  Neither Tom nor I have been to New York.

  汤姆和我都没去过纽约。

  Neither you nor he has come home early. 你和他都未早回家。

12. journey和trip的区别

  (1)journey适用范围很广,可指陆路、海程或飞程。但在距离较短时一般不用这个词。

  It's over 40-hour journey by train from Beijing to Yunnan.

  从北京到云南乘火车需要四十多小时的路程。

  Have a good journey! 祝你旅途愉快!

  (2)trip严格说来指"短途旅行",目的可以是公事或娱乐。但在日常用语中也可与 journey互换。

  We're planning to make a trip to the Great Wall.

  我们正计划去长城游览一次。

关于现在完成时的教学建议

  既然本单元的重点和难点是动词的现在完成时态,而这个时态又是英语动词时态中较难掌握的一种,我们应将它的特点、含义和用法等通过举例和口笔头练习交代清楚。

  1.现在完成时态的含义是表示过去发生的或已完成的动作对现在造成的影响或结果。特点是既涉及过去,又联系现在:动作是过去发生的,结果是现在存在的。举两个例子说明:

  She has come. (她来了。)

  这句话说明两点:1)她是过去某一时候来的; 2)她现在还在这里。而主要说明她还在这里了。

  动词用现在完成时态,表示“现在还存在的过去某一动作的结果或影响”。至于她过去是什么时候来的,是十分钟以前还是一小时以前,并不是这句话所要说明的情况。

  She has gone. (她走了。)

   从这句话中动词所用的现在完成时态可以看出“走”的动作是过去发生的,而对现在所造成的结果是她不在这里了。

   动词现在完成时态所表示的“现在的影响或结果”可以包含各种情况:看得见的或看不见的,肯定的或否定的;

  Look! The blackboard is so clean now.

  He has cleaned the blackboard. (他已经擦过黑板了。)

  这句话所表示的结果是看得见的,黑板现在是干净的。

   He speaks French so fluently. He learned it in Paris. He was there for two years.

  He has studied French. (他学过法语。)

   这句话所说明的结果是看不见的:他现在懂法语。

  上述两句如加上not,never或别的否定词,所说的结果就是否定的:

   He hasn't cleaned the room. Everything here is in a mess. (他没有打扫房间。)

   结果是:房间不干净。

   He has never learned English. He doesn’t know English. (他从来没有学过英语。)

   结果是,他不懂英语。

  不管是哪一种影响或结果,只有在目前还存在的情况下才可用现在完成时态。一旦结果或影响不复存在,就不能用现在完成时,而应用一般过去时。这就是现在完成时和一般过去时的区别所在。试看下面的例句:

   He has cleaned the room. Now room is very cleanly. (他已经打扫房间了,现在房间很干净。)

   He cleaned the room an hour ago,but it's dirty now. (他一小时前打扫过房间,可是现在房间又脏了。)

  上面的例子表明:一般过去时说的是过去发生的或已经结束了的动作,它和现在没有直接关系;即使事实上和现在有关系,说话时也不强调这种关系,而只是指出那个动作发生在过去某一时间。而现在完成时,却正要强调过去的动作和现在的关系。

  我们可以设计一对对用词相近而动词时态不同的句子,让学生说出它们意思上的差别,以帮助他们弄清现在完成时的含义以及它和一般过去时的不同。例如:

  1)The teacher has written some new words on the blackboard.

    The teacher wrote some new words on the blackboard.

  2) I’ve just washed my clothes.

    I washed my clothes before supper.

  2.英语动词的现在完成时态是由助动词have(has)+ 动词的过去分词构成的。规则动词的过去分词和它的过去式相同,即在原形后加-(-d)。可参考教参上的不规则动词的过分分词分类,以便记忆.

 注1:情态动词只有原形过去式,没有过去分词。

  can could may might must must will would shall should

 注2:个别动词有两个过去式和两个过去分词,一个为规则变化,另一个为不规则变化:

  3.为了使学生能掌握一般过去时和现在完成时的不同用法,可以编些带有这两种时态的对话,让学生进行英汉互译的口笔头练习。下面的对话供参考:

  1) Have they cleaned the room?

    Yes, they've already cleaned it.

    When did they clean it?

    They cleaned it an hour ago.

  2) She has gone to London, hasn't she?

    Yes, she has.

    How did she go there?

    She went there by plane.

  3) Have you got Kate's phone call?

    Yes, I've just got it.

    What did she say?

    She wanted me to ask you to call back.

  以上对话中的有关单词和短语,可用替换词语,以增加练习量。

关于训练听说读写能力的教学建议

一、听力训练

 1.在对话与课文的教学当中,可设计先让学生想像对话的场景和可能发生的事情,再放对话的录音,加强学生的注意力,以达到提高听力的效果。

 2.可在听录音这之前、听录音之后,分别给出不同的问题来引导学生在听的时候要有所侧重。如第6课的问题可设计如下:

  I. What sports do you like best?

  What is the surfing like?

  Where did surfing first start?

  o Why is Waikiki one of the best beaches for surfing in Honolulu?

  o Who surfs three times a day if possible?

  o How does Jake Booth make a living in Honolulu?

  o When does he go surfing every day?

二、口语训练

 1.设计场景,让学生反复练习句型对话,如:

  1) Have they cleaned the room?

    Yes, they've already cleaned it.

    When did they clean it?

    They cleaned it an hour ago.

  2) She has gone to London, hasn't she?

    Yes, she has.

    How did she go there?

    She went there by plane.

  3) Have you got Kate's phone call?

    Yes, I've just got it.

    What did she say?

    She wanted me to ask you to call back.

 2.在第5课的教学中,可让学生先根据课本中的图片,想一想Ted与Bruce在谈论什么,并根据提供的关键句,设计他们的谈话。可提供下列句型:

  What's the surfing like today?

  How long have you been …?

  Have you ever been to …?

  Would you like to have a try?

 3.复述第6课课文

  细读第6课课文后,以第三人称来复述冲浪运动的特点等。

三、阅读训练

 1.先引导学生看关于课文内容的问答题和填空题,然后让学生带着问题再去读课文。

  第6课可设计如下问题:

  Where did surfing first start?

  Why is Waikiki one of the best beaches for surfing in Honolulu?

  What's the difference between serious surfers and the so-called "beach boys"?

  Is Jack Booth a serious surfer or a beach boy?

  How does he make a living in Honolulu?

  When does he go surfing every day?

 2.回答问题后,再细读课文,找出每一段的主题句。

  如:Surfing is one of the world's most popular water sports.

  Waikiki is one of the best beaches for surfing in Honolulu.

  There is a big difference between serious surfers and the so-called "beach boys"

  About the man named Jake Booth who gave up his job to surf in Hawaii and His opinions on surfing.

四、写作训练

 1. 根据第八课的短文,组织学生用英语仿写一篇关于Li Lida游过海峡的新闻报道,全文不少于10句话。要求写清楚发生了什么事,事件的地点、时间、人物,以及相关人士的评论等。

 2. 以My Favourite…为题准备一篇英文短文,应不少于10个句子。题目范围可放宽,可以自由选择,只要有个人的喜好就可以。如My Favourite Animal/ Food/ Farm/ Life/ Color/ Sport/ Season/ Song/ film …

 3. 书面表达

  假设你刚从海南岛度假回来,享受了阳光,沙滩,冲浪,美食…… 根据本单元所学的内容,用英语写一篇大约50字左右的短文。
