教学建议

关于教材内容的分析

本单元是围绕"Makeourworldmorebeautiful"这一主题，结合现在完成时态这一语法功能项目展开教学活动的。谈论了过去与现在的时间关系，着重讲述了现在完成时态的第二种用法，即从过去开始，持续到现在的动作或状态，所使用的谓语动词一般都是延续性动词。本单元还讲述了延续性动词和非延续性动员与时间的搭配关系；for和since引导的时间状语和完成时态的连用。本单元还出现了有关事情发生的时间问题的对话和日常用语，讨论了有关环境卫生的问题，要求我们要规范自己的行为。

本单元短语与交际用语

1.短语和习惯用语

2.日常交际用语

I'vebeento…

ThereisnothingbeforeSunday,Iamafraid.

I'mafraidI'llbefilledupthisweek.

I'mafraidIcan'tmeetyouhere.

I'msorry,but...won'tbesoconvenientforme.

本单元重点难点分析

1.havebeen(to)与havegone(to)

havebeen与havegone都表示现在完成时态，表明动作已经发生了，但它们之间的含义是有不同的。

1）"havebeenin+地点名词"或者"havebeen+表位置的副词"含义是"在某地呆得过多久"。例如：

MrZhanghasbeeninthisschoolfortenyears.Heknowseveryonehere.

张先生在这所学校呆了十年。

IhavebeenheresinceIbegantowork.It'sjustlikemyhome.

我工作以来一直呆在这里。

2）"havebeento+地点名词"表示"曾经到某地去过（多少次）"。例如：

MissBrownhasbeentoChinatwice.That'swhyshespeaksJapaneseverywell.

布朗小姐来过中国两次。

Haveyoueverbeenherebefore?

你以前到过这儿吗？

3）"havegoneto+地点名词"或"havegone+表位置的副词"其含义是"到某地去了"（人已不在此地），注意：这种结构不用于第一人称，也不用于第二人称，它仅用于第三人称。请看下面一段对话：

A:Where'sTom?

B:He'sgonetotheshop.

A:HasMarygonetherewithhim?

B:No,shehasn't.

A：汤姆在哪里？

B：他到商店去了。

A：玛丽跟他去了吗？

B：没有。

2.BusinessmenareafraidofnewspapersandTVstations.生意人害怕报纸和电台。

beafraidof…意思是"害怕……"。afraid是形容词，在句中只能作表语，后跟名词或动词的-ing形式（指自己不能决定而突然发生的事），与frightened的意思相同。beafraid后也可跟动词不定式表示"害怕做某事"即：beafraidtodosth.。另外，afraid后还可跟that引导的宾语从句，意思是"担心，恐怕"。例如：

（1）Iamafraidofmice.我害怕老鼠。

（2）Don'tbeafraidofmakingmistakes.不要怕犯错误。

（3）I'mafraidtotellherthetruth.我不敢告诉她真相。

（4）Iamafraidyouareill.恐怕你是病了。

（5）I'mafraid(that)wemaynotcatchthetrain.我担心我们可能赶不上火车。

3.Assoonasotherpeoplehearit,theygooutwiththeirrubbishandthrowitin.

当人们一听到它，他们就出来把垃圾扔进去。

assoonas-……就……，引导时间状语从句，表示主句的动作紧跟从句的动作发生。必须注意assoonaspossible（onecan），它表示"尽可能快地"。

【例】

（1）He'llwritetomeassoonashegetstoBeijing.

他一到北京就会给我写信。

（2）Youshoulddoyourworkassoonaspossible.

你应尽快地做事。

4.…takingcareofourenvironmentisveryimportant.保护好我们的环境是非常重要的。

(1)takecareof保护，照顾，保管。如：

Pleasetakegoodcareofyourbooks.请保管好你们的书。

CanyoutakecareofmybabywhileI'maway?我出去时你能为我照顾我的孩子吗？

(2)"Takingcareofourenvironment"在这里是动名词短语作主语。也可以说：It'sveryimportanttotakecareofourenvironment.

5.It'sourdutytokeepourenvironmentcleanandtidy.保持我们的环境干净整洁是我们的责任。

（1）it在这里是形式主语，真正的主语是"tokeepourenvironmentcleanandtidy"

又如：It'sapleasantwaytohelpkeepourcityclean.

（2）keen后面可跟带现在分词的复合结构。如：

Hekeptmewaitingforalongtimeyesterday.他昨天让我等了很长时间。

keep后面也可跟带形容词的复合结构。如：

Youshouldtakemoreexercisetokeepyouhealthy.你应该多运动来保持健康。

6.Ifeveryonemakesacontributiontoprotectingtheenvironment,theworldwillbecomemuchmorebeautiful.如果每人都对保护环境做出贡献，那么世界将变得更加美丽。

makeacontributionto…意思是"对……做贡献，捐赠"。to是介词后跟名词或动词的-ing形式。例如：

（l）Thomasmadeagreatcontributiontotheworld.托马斯·爱迪生对世界做出了很大的贡献。

（2）Itisourdutytomakeacontributiontoprotectingtheenvironment.为环境保护做贡献是我们的责任。

make是英语中非常活跃的动词之一，和不同的词搭配具有不同的含义。又如：

makeaface做鬼脸makealiving谋生

makeamistake犯错误makefriendswith交朋友

makefunof开玩笑makeone'sway挤出一条路

makeroomfor让座makeupone'smind下决心

MyfriendEmmamadefunofmyjoboncetime.Shesaidthatmyjobisrathermakingalivingthancareermanage.Imadeupmymindtorunmycompanysuccessfully,whichcouldmakeherrealizeshehadmadesuchamistake.ThenImademywayinmasssociety.Imadegoodasamanager.IstayhereandmakesurethatIhavemadeagoofthebusiness.ImakeofwhatEmmahavedoneforme,luckily,Imadefriendwithher.

7.Themoretrees,thebetter的结构

这里是"themore，themore…"句型表述结构，它的意思是"越多越好；越……，越……"。例如：

Startyourwork,thesooner,thebetter.

开始工作吧，越快越好。

ThemoreIthinkofit,thehappierIam.

我越想越高兴：

Theharderyouwork,thegreaterprogressyouwillmake.

你越用功，进步就越大。

Thelongerwestayedthere,themorewelikethepeoplethere.

我们在那里呆得越久，越喜欢那里的人民。

注意：在"themore…，themore"这个句型中，"the"不能省略。

8.…needtodobetterinprotectingtheenvironment.需要在保护环境方面做得更好。

dowellin在某方面干得好。dobetterin在某方面干得更好。

在in后面加名词或动名词。例：

Hedoeswellinplayingfootball.他足球踢得很好。

9.延续性动词与非延续性动词

(1)延续性动词

表示动作能够持续发生一段时间的动词。如：

be,have,know,work,live,study,teach,speak,talk,draw,wait,wear,walk,sleep等。

MissGaohasbeenheresince7:00.

高小姐七点起就到这儿了。（此句中不能用arrived或come）

Ihavehadthebikeforfiveyears.

这辆自行车我已经买了五年了。（不能用bought）

(2)非延续性动词

表示一个动作刚刚发生即告结束。如：

come,go,arrive,reach,see,hear,close,leave,begin,start,lose,fall,join,die,getup等。它们可以用于完成时态的第一种，说明某个动作的结果还存在。但它们不可以用于完成时态的第二种。

GrandpaWanghasdied.王大爷已经去世了。

Thefilmhasbegun.电影已经开映。（现正放映）

这类动词不能和表示一段时间的状语连用。如：要表达"王大爷已经去世两年了"应这样写：GrandpaWanghasbeendeadfortwoyears.而不能写成：

GrandpaWanghasdiedfortwoyears.

注：在for+时间段或since+时间点的词组或句子上进行画线部分提问要用howlong。同时用howlong开始的句子中的谓语要用延续性的动词（时态不限）。

关于现在完成时的讲解

1.表示过去发生或己经完成的动作对现在造成的影响或结果

现在完成时的常用副词是never"从来没，不"，ever"曾经"，just"刚刚"，already"已经"，yet"已经，仍然"。其中already通常用有肯定句中，yet通常用在否定句和疑问句中。yet在否定句中要译成"仍然"，"还"，在疑问句里要译成"已经"。

（1）常already,just和yet等连用，如：

一Haveyoufinishedyourworkyet?你做完你的工作了吗?

一Yes.Ihave.I'vejustfinishedit.我做完了，我刚做完。

I'vealreadyfinishedit.我已经完成了。

Ihaven'tfinishedityet.我还没做完。

（2）也可与ever,never连用

-Haveyoueverbeentothepark?你曾去过那个公园吗?

-Yes,Ihave./No,Ihaven't,Ihaveneverbeentothepark.

是的，我去过。/不，我没去过，我从未去过那个公园。

2.现在完成时与动词的延续性

（1）for和since时间状语与现在完成时连用，表示从过去某一时间开始并一直延续到现在的情况，因此谓语部分不能用非延续性动词，常见的非延续性动词有：

close,leave,see,come,hear,buy,borrow,begin(start),join,die,finish等。

（2）在否定句中非延续性动词可以与for或since引导的表示段时间的状语连用，如：Ihaven'tseenhimforalongtime.（此句是否定句，非延续性动词see与foralongtime连用）

3.注意现在完成时和一般过去时的区别。

A.一般过去时通常表示在过去某一具体时间发生的动作，与现在没有什么联系。现在完成时与现在有联系，它表示过去的动作对现在产生的影响，结果。例如：

Hecleanedtheroomanhourago.他一小时前打扫了房间。

Hehascleanedtheroom.Yousee,it'sverycleannow.

他打扫了房间。你瞧，现在挺干净的。

B.当句子有表示过去具体时间的状语时，通常用一般过去时。现在完成时不能与确定的过去时间状语连用。例如：

WelearnedLesson4lastweek.我们上星期学了第4课。

不能用Wehavelearnedlesson4lastweek.

关于训练听说读写能力的教学建议

一、听力训练

除了课堂的听力训练以外，可以提供给学生一些关于现在完成时的听力练习，完成一些替换练习、完成句子、回答问题等。在复习了前三单元内容的同时，还能达到了能让学生听懂相关语法的语句，并灵活运用现在完成时和一般过去时来回答问题。所涉及的范围可以包括以时间点为线索的描述过去经历、简历求职、假期生活等。二、口语训练

1.看图说话

向学生展示两幅关于环境的图片，其中，一幅是未受污染的环境，一幅是受污染的环境。让学生观察并对比它们，看看哪一幅beautiful，哪一幅是已受污染的环境。然后完成对BadEnvironment和GoodEnvironment的描述，以及人们曾对这种环境做过什么。

可提供下列词汇与词组：

pour,waste,dirty,clean,terrible,donoharm,writeabookontheenvironment,pickuprubbish,collectrubbish,keep/maketheplaceclean/dirty，damagedbadly,inpublicplace,itseemslike,itisourdutyto,planttree,improve,recycle,makeacontributionto，etc.

2.简述自己和他人的经历

分两步进行练习：

1)让学生们完成自己的简历，写清楚时间、地点、当时所做的事情或身份。

2)将学生分成两组，A组和B组。两组成员数量相同，并分别在对方组互相指定一名交谈者。分别让A组的成员向B组相对应的成员叙述自己的经历，同时B组相应同学做好记录，然后，B组同学复述A组同学的经历。再分别交换角色，由B组叙述，A组复述。

注意提醒同学，一般过去时和现在完成时的使用应准确，叙述他人的经历时，应注意他/她本人叙述时的用词和所用时态。

三、阅读训练

在学习第10课的课文时，注意三种表述的不同用词和语态：表述过去的事情、表述现在已完成或已产生的影响、下结论或展示希望。可让学生阅读后进行分析和归纳整理，将三种表述的用法和语言环境分别选出，形象地理解什么时候使用哪种时态是正确的。有代表性的句子有：

OnedayIwasvisiting…Myfriendsaid…

Itisourduty…Youmightask…

Haveyoueverthrown…HaveIeverpickedup

还可将本课有用的短语和词组挑出来，进行造句练习：

apieceofbeautifulmusic

pickup

collectrubbish

keepourcityclean

takecareof

throwonto

spitinapublicplace

cutdown

protectourenvironment

makeacontributionto

四、写作训练

1.环境保护是个世界性的话题，它需要每个人来进行努力。除了对一些生态环境进行保护以外，还要保护我们身边的环境。根据教材第10课的内容，将课文改写成Protectourenvironment的百字短文。建议大家如何来保护我们的生活、工作或社会环境。除了课文所涉及的内容，可以加入自己的想法和建议。

2.组织学生完成一份关于自己身边环境的英文调查报告。提醒学生先准备好所要调查的项目，以及各项所需要的指标、数字、表格等。主题可包括水、空气、土地、河流、资源、城市等。字数在80-100单词。

可提供下列词汇与短语：

wastewater,clearair,earth,city,river,dirty,rubbish,spit,throw,collect,pickup,draw,damagedbadly,inpublicplace,itseemslike,itisourdutyto,planttree,improve,recycle,makeacontributionto,make/keepitclean,hope,wish,etc.

在总结时，建议根据不同的话题，将学生分成若干组，分别选出代表进行报告表演。鼓励每个学生都积极参与，营造热烈的报告气氛，让学生尽量用英文进行报告。在完成此报告时，学生们应掌握了关于环境保护的相关知识，意识到保护环境的重要性，并主动去宣传相关知识。

3.向学生展示三个场景的图片或动画：

1）学生在学校内随便乱扔东西，使校园看起来很脏；

2）学生们在校园内很卖力地打扫卫生；

3）整个校园变得干净整洁。

根据这三个场景完成作文《校园的变化》。
