当“quantitiesof/aquantityof+名词”作主语时，谓语动词的数取决于quantity的数，而与所修饰的名词无关。1)Thereisalargequantityofsnowinthisarea.2)Thereare

quantitiesofsnowinthisarea.我们学过amount，可构成agreatamountof，表示“大量的”，其后通常跟不可数名词。当“anamountof/amountsof+不可数名词”作主语时，谓语动词的数同样取决于amount的数。Alargeamountofmoneywasspentonthebridge.Largeamountsofmoneywerespentonthebridge.谓语动词的数同样取决于amount的数

根据汉语提示，补全下列句子。

Largequantitiesofbeer_____________(已被售出)inthisshop.2.____________________________________________(大量的学生)crowdedintothelibrary.havebeensoldQuantitiesof/Aquantityofstudentsresultin1.Thereisnodoubtthattheearthisbecomingwarmerandthatitishumanactivitythathascausedthisglobalwarmingratherthanarandombutnaturalphenomenon.

本句的主句是Thereisnodoubt，从句是两个由that引导的同位语从句。Thereisnodoubtthat...是固定句型，意为“毫无疑问……”，that引导的是同位语从句，用来进一步补充说明doubt的具体内容。[考例]Someresearchersbelievethatthereisnodoubt______acureforAIDSwillbefound.A.whichB.that

C.whatD.whether[点拨]

根据固定搭配thereisnodoubtthat...可知选B。Thereisnodoubtthat….Thereissomedoubtwhether….主句为肯定句时，doubt后使用连词whether。主句为否定句时，doubt后则使用连词that。新课程P612.[考例1]Itisnotwhoisrightbutwhatisright______isofimportance.whichB.it C.that D.this根据强调句型的判断方法：将itis和that去掉后，此句成为Notwhoisrightbutwhatisrightisofimportance，是一个完整的句子，故此题是一个强调句型。[考例2]Idon’tmindhercriticizingme,but______ishowshedoesitthatIobjectto.A.it B.that C.this D.which[点拨]

去掉itis和that后，本句相当于...,butIobjecttohowshedoesit，是个完整的句子。故此句是it强调句型，被强调部分是宾语从句。2.Withoutthe‘greenhouseeffect’,theearthwouldbeaboutthirty-threedegreesCelsiuscoolerthanitis.

如果没有温室效应，地球会比现在冷33℃。▲这是一个含蓄虚拟条件句

Hewashavingameetingwithhisstudents;otherwisehewouldhavecome.

他当时正与他的学生进行讨论，否则的话他就来帮我们了。Hefeltverytiredyesterday,orhewouldhaveattendedtheparty.

他昨天很累,不然他就参加那个聚会了。

应该注意有时假设的情况并不以条件从句形式表示出来，而是通过一个介词短语或其他方式表示。常用的词或短语有：without,butfor,butthat,otherwise,or,but等。Withoutyourhelp(=Ifwehadnothadyourhelp),wecouldnothavesucceeded.

要是没有你的帮助，我们是不会成功的。

Butforelectricity(=Iftherewerenoelectricity),therewouldbenomodemindustry.

要是没有电，就不会有现代工业。3.ItwasascientistcalledCharlesKeelingwhomadeaccuratemeasurementsoftheamountofcarbondioxideintheatmospherefrom1957to1997.

是一位名叫查尔斯·奎林的科学家把

1957至1997年期间大气层中二氧化碳的含量作了精确的统计。该句是一个itwas...who强调句。ascientistcalledCharlesKeeling是被强调部分，其中calledCharlesKeeling为过去分词短语作后置定语，修饰ascientist。4.Ontheotherhand,therearethose,likeGeorgeHambley,whoareopposedtothisview,believethatweshouldnotworryabouthighlevelsofcarbondioxideintheair.

在另一方面,还有一些人，对这一观点持反对态度，像科学家乔治·汉布利，他们认为我们不必担心空气中高含量的二氧化碳。ontheotherhand:usedtogiveanotheropinionorfactthatshouldbeconsideredaswellastheoneyouhavejustgiven另一方面
