ALessoninaLab教案
典句精讲
1.Thesciencefacilitiesareverygoodwithlaboratoriesthathaveallthelatestequipment.?
这些科研设备非常好,实验室配有最新的设备。?
with在此句中意思为“带有……”,其引导的短语对句子作附加说明,thathaveallthelatestequipment为定语从句,修饰laboratories。?
2....andthesearealwaysveryinteresting,asthelecturesarepeoplewhohavemaderealdiscoveriesintheirareasofscience.?
这些讲座总是很有趣的,因为作讲座的人是在各自的科研领域里真正有所发现的人。?
asconj.“因为,由于”,在本句中引导原因状语从句。as作连词可以引导多种状语从句,主要有时间、原因、方式、比较、让步等从句。?
3.TheNobelPrizeisthehighestscientificprizethereis,soweshouldbeveryproudofthat.?
诺贝尔奖是目前科学方面的最高奖,因此我们为此感到骄傲。?
thereis为定语从句,修饰prize。?
4.Itisimportanttoknowhowtheyreactwithdifferentsubstances,forexample,waterandoxygen.?
了解它们如何同像水、氧气这样的物质发生反应的是非常重要的。?
1)it是形式主语,真正的主语是动词不定式to后面的部分。?
2)how引导的句子作know的宾语。?
reactwith同……发生反应。?
forexample是不完全列举,“例如”。完全列举时用thatis。
拓展延伸注意此处空半格以it作形式主语或形式宾语的动词有feel,consider,find,believe,make,take,imagine,think,suppose,count,regard等。在这种结构中,被替代的成分要置于句尾。?
5.Leavethetubeforoneweek.把试管放置一个星期。?
1)leave意为“维持,使保持一定状态”,允许在某一种状态。?
2)leave作“离开”讲时是及物动词;作“去,出发”讲时,是不及物动词;
还可作“遗忘,忘掉”讲,与forget近义,但搭配不一样,leavesth.+地点状语,而forget只加sth.,不加地点。如:
Ileftmydictionaryinmydormitory.?
Iforgotmydictionary.
拓展延伸注意此处空半格leave作“维持,是保持某一状态”讲时,其结构经常是:后跟副词、分词、介词、形容词等作宾语补足语的复合结构。如:?
IamsorryIhaveleftyouwaitingformeforsolongtime.?
Hisanswerleftmeunhappy.?
6.Ourchemistryteacher,MrLongford,takesustopublicsciencelecturesaboutfourtimesaterm,andthesearealwaysveryinteresting,asthelecturersarepeoplewhohavemaderealdiscoveriesintheareaofscience.?
我们的化学老师朗福德先生,大约每学期带我们去听四次大众科学讲座,这些讲座是非常有趣的,因为作讲座的人在他们所从事的科学领域都有实际的发明。?
1)这句话是由and连接的两个并列句子,连个句子的主语分别是:ourchemistryteacher和these。后面的句子又是一个由as连接的原因状语从句,表示明显的原因,意为“由于、鉴于”。?轻轻告诉你? 
Hethatseeksgains.有所求则有所获。
2)MrLongford作ourchemistryteacher的同位语。
拓展延伸注意此处空半格1)as除了引导原因状语从句外,还经常引导时间状语从句。在此用法上,应注意同when和while的区别。?
when表示某个具体的时间,所引导的从句的动作或与主语的动作同时发生,或先于主语的动作发生,when可指一段时间,也可指点时间,既可表示一时性的动作,也可表示持续性的动作。?
while只表示持续性的动作或状态,不能表示一时性的动作或短暂动作。?
as所表示的动作与主句的动作同时发生,具有延续含义,一般同延续性动词连用。as,while可译为“一边……一边……”,as还有”随着……”的意思。?
2)as引导让步状语从句作“尽管”讲时,须倒装,即把强调的部分(多为名词、形容词、副词)放句首,当所强调的表语是单数名词时,须把不定冠词去掉。?

10.(2009年高考四川卷)—MayIopenthewindowtoletinsomefreshair?
—________
A.Comeon!B.Takecare!
C.Goahead!D.Holdon!
解析:选C。问句是在请求许可,句意是:我可以打开窗户,让新鲜空气进来吗?四个选项中只有Goahead!表示说话者同意,意为“打开吧!”Comeon!用来催促对方,意为“快点吧!”Takecare!小心!Holdon!坚持住!。

★11.(2009年高考安徽卷)—Couldyoubesokindastoclosethewindow?
—________.
A.Withpleasure B.Goahead
C.Yes,pleaseD.That’sOK
解析:选A。问句的意思是“你可不可以好心把窗户关上?”这个情景是请对方做某事,所以回答不能用Goahead,而是Withpleasure(愿意)。
★12.(2010年高考重庆卷)—Honey,let’sgooutfordinner.
—________Idon’thavetocook.
A.Forgetit!B.That’sgreat!
C.Why?D.Goahead.
解析:选B。句意:——亲爱的,我们去外面吃晚饭吧。——太好了!我不必做饭了!由语境Idon’thavetocook可知,听话者非常赞同说话者提出的建议,故答案为B项。forgetit“没关系”“不必太在意”;why?“干嘛?”goahead“去做吧”,都不符合语境。

13.—Theplane________arriveat11∶30,butwasalmosthalfanhourlate.
—Commonpractice.
A.wasaboutto B.waslikelyto
C.wassupposedtoD.wascertainto
解析:选C。besupposedtodo“本应该”。

★14.Themessageisveryimportant,soitissupposed________assoonaspossible.
A.tobesentB.tosend
C.beingsentD.sending
解析:选A。句意:这条信息很重要,所以要尽快发出去。besupposed后接不定式结构,意为“理应,应该”,排除C项和D项。it指message,message和send之间为被动关系,排除B项,故A为正确答案。
句型梳理
① Itishardtothinkofaworldwithoutmetals.(P44)
很难想象一个没有金属的世界。
 本句中,it为形式主语,真正的主语是不定式短语tothinkof...,构成Itis/was+adj.+todosth.的结构。
Itis+adj.+forsb.todosth.该句式中,作表语的形容词只能说明不定式的行为性质和特点,不能说明不定式的执行者。常见的这类形容词有:easy,important,difficult,hard,possible,impossible,necessary等。
Itis+adj.+ofsb.todosth.该句式中,作表语的形容词表达不定式的逻辑主语的品行、性格或性质。常见的这类形容词有:kind,nice,good,honest,careful,careless,clever,wise,stupid,foolish,rude,polite,impolite等。
Itis+adj./n.+that?clause
Itis+nogood/usedoingsth.
①Itiseasiertosaythantodo.说比做容易。
②Itisnogoodplayingcomputergames.玩电脑游戏没有好处。
③Itisashamethathedidn’tpasstheexam.
很遗憾他没有通过考试。
④Itissaidthattheticketshavebeensoldout.
据说票已售完。
15.(2010年高考大纲全国卷Ⅱ)Thedoctorthought______wouldbegoodforyoutohaveaholiday.
A.thisB.that
C.oneD.it
解析:选D。句意:医生认为度假对你有好处。本题考查代词it作形式主语。根据句意不定式短语tohaveaholiday在宾语从句中作真正的主语,只有it可作形式主语,故选D项。

★16.(2009年高考天津卷)Itisobvioustothestudents________theyshouldgetwellpreparedfortheirfuture.
A.asB.which
C.whetherD.that
解析:选D。句意是:对学生来说,很明显的是他们应该为将来做好准备。It是形式主语,________theyshouldgetwellpreparedfortheirfuture是主语从句,作真正的主语。这个引导词起引导作用,不作成分,故用that。
② Hereisatablewiththemetalsthatreactmostatthetop,andthemetalsthatreactleastatthebottom.(P44)
这儿有一个图表,那些反应最强烈的金属在上部,反应最不强烈的在下部。
 这是一个倒装句,正常语序是:Atablewith...ishere.
(1)在there,here引导的句子中,谓语是be,exist等表示状态的不及物动词时,句子要全部倒装。
(2)在there,here,now,then,thus等开头的句子里,谓语动词是come,go,follow等时,句子要全部倒装。
(3)here,there引导的句子,当主语是代词时,不倒装,且此类句子不用进行时。
①HerearewhatIwantyoutodo.下面是我想让你做的事情。
②Theregoesthebus.公共汽车走了。
③Nowcomesmyturn.现在该轮到我了。
17.(2010年高考江苏卷)—Iseveryonehere?
—Notyet...Look,there________therestofourguests!
A.comeB.comes
C.iscomingD.arecoming
解析:选A。句意:——都到了吗?——还没有……看,其余的客人过来了!本题考查主谓一致。本句中there放在句首,句子采用了倒装句式,谓语动词应该根据句子的主语therestofourguests来判断,B项和C项为第三人称单数形式,可排除;come用于进行时态表示将来的动作,不合题意,可排除;A项谓语动词与主语一致,故答案为A。

★18.(2009年高考福建卷)Foramomentnothinghappened.Then________allshoutingtogether.
A.voiceshadcomeB.camevoices
C.voiceswouldcomeD.didvoicescome
解析:选B。考查倒装结构。表示时间的副词now,then及表示方位的副词here,there等位于句首,与位移性动词come,go,arrive等连用,且主语不是人称代词,此时用完全倒装。从前一句可知此处描述的是过去的事情,所以用一般过去时。

话题导入
人类从日常生活到宇宙探索都离不开科学技术。如果没有科学的发展,我们将仍然处于愚昧无知的原始状态,科学技术是第一生产力,它推动了社会经济、文明的发展,使我们人类成为了宇宙的主人。作为中学生,我们应该以“八荣八耻”中的“以崇尚科学为荣、以愚昧无知为耻”为行为准则,把智慧和热情投入到科学研究和探索中。

背景资料
什么是铁??
铁位于周期表第四周期第Ⅷ族。元素符号为Fe,原子序数为26,是一种重要的过渡元素。光亮的银白色金属,密度7.86g/cm3,熔点1535℃,沸点2750℃。纯铁的抗蚀力相当强,但通常的铁都含有碳和其他元素,因而使它的熔点降低,抗蚀力也减弱。铁有延展性和导热性,也能导电。但导电性比铜、铝都差。铁能被磁体吸引,在磁场作用下,铁自身也能产生磁性。?
铁为什么会生锈??
铁放的时间长了就会生锈。铁容易生锈,除了由于它的化学性质活泼以外,同时与外界条件也有很大关系。水分是使铁容易生锈的物质之一。然而,光有水也不会使铁生锈,只有当空气中的氧气溶解在水里时,氧在有水的环境中与铁反应,才会生成一种叫氧化铁的东西,这就是铁锈。铁锈是一种棕红色的物质,它不像铁那么坚硬,很容易脱落,一块铁完全生锈后,体积可胀大8倍。如果不除去铁锈,这海绵状的铁锈特别容易吸收水分,铁也就烂得更快了。??
