這會(huì)有什么后果呢？4.range

種類；范圍in/withinrange在射程之內(nèi)outof/beyondrange

在射程之外e.g.Thisisoutsidetherangeof

ourstudy.

這不屬于我們研究的范圍。Thisrestauranthasbecomepopularforitswide______offoodsthatsuitalltastesandpockets.A.division B.area C.range D.circle【點(diǎn)撥】

句意為：這家飯館的食品種類豐富，可以滿足不同口味和收入的顧客，因此深受大家的喜愛。C5.quantitiesof大量的，其后既可以跟可數(shù)名詞，也可以跟不可數(shù)名詞。Insummer,quantitiesoffruitandvegetablesarepreservedinthefridge.Roseownsquantitiesofbooks.

當(dāng)“quantitiesof/aquantityof+名詞”作主語時(shí)，謂語動(dòng)詞的數(shù)取決于quantity的數(shù)，而與所修飾的名詞無關(guān)。1.Thereisalargequantityofsnowinthisarea.2.Therearequantitiesofsnowinthisarea.我們在高一學(xué)過amount這個(gè)詞，也可構(gòu)成agreatamountof，表示“大量的”，其后通常跟不可數(shù)名詞。當(dāng)“anamountof/amountsof+不可數(shù)名詞”作主語時(shí)，謂語動(dòng)詞的數(shù)同樣取決于amount的數(shù)。

根據(jù)漢語提示，補(bǔ)全下列句子。

Largequantitiesofbeer_____________(已被售出)inthisshop.2.___________________________________________(大量的學(xué)生)crowdedintothelibrary.havebeensoldQuantitiesof/Aquantityofstudentsresultin6.tend

觀察tend在下列各句中的詞性、含義及用法。2.Davidtendstowardsobesity.Janettendstogetveryangryifyoucan’tsatisfyherdemands.3.Sofiawastendingtohersoninthebedroom.5.Marywilltendthegardenwhileyou’reonvacation.4.Thenurseskillfully

tendedthesoldiers’wound.

從以上例句我們可以看出，tend既可作及物動(dòng)詞也可作不及物動(dòng)詞。作不及物動(dòng)詞時(shí)，意為“易于”，構(gòu)成tendtodosth.結(jié)構(gòu)，意為“易于做某事”（句1）；“______”，后常接towards或to（句2）；“照顧”，構(gòu)成tendtosb./sth.結(jié)構(gòu)（句3）。作及物動(dòng)詞時(shí)，意為“____________”（句4、句5）。趨向照顧，護(hù)理7....causingtheglobaltemperaturetogoup.goup上升；增長；升起?！究祭俊狣oyouthinkthathousingpricewillkeep______intheyearstocome?—Sorry,Ihavenoidea.A.liftingup B.goingupC.bringingup D.growingupB【點(diǎn)撥】

選B。句意為：你認(rèn)為房價(jià)在未來幾年內(nèi)會(huì)持續(xù)上漲嗎？liftup拿起，舉起；bringup撫養(yǎng)，培養(yǎng)，提出；growup長大，成長。8.Evenifwestartreducingtheamountofcarbondioxide...evenif/though即使

選C。句意為：這些工程師太忙了，以至于雖然他們有興趣進(jìn)行戶外體育運(yùn)動(dòng)，但是沒有時(shí)間。C

重點(diǎn)句子1.Thereisnodoubtthattheearthisbecomingwarmerandthatitishumanactivitythathascausedthisglobalwarmingratherthanarandombutnaturalphenomenon.

本句的主句是Thereisnodoubt，從句是兩個(gè)由that引導(dǎo)的同位語從句。Thereisnodoubtthat...是固定句型，意為“毫無疑問……”，that引導(dǎo)的是同位語從句，用來進(jìn)一步補(bǔ)充說明doubt的具體內(nèi)容。[考例]Someresearchersbelievethatthereisnodoubt______acureforAIDSwillbefound.A.whichB.that

C.whatD.whether[點(diǎn)撥]

根據(jù)固定搭配thereisnodoubtthat...可知選B。Thereisnodoubtthat….Thereissomedoubtwhether….主句為肯定句時(shí)，doubt后使用連詞whether。主句為否定句時(shí)，doubt后則使用連詞that。itis...that...在此句中構(gòu)成強(qiáng)調(diào)句型，強(qiáng)調(diào)的是主語humanactivity。強(qiáng)調(diào)句型除謂語不能強(qiáng)調(diào)外，可強(qiáng)調(diào)主語、賓語或狀語。[考例1]Itisnotwhoisrightbutwhatisright______isofimportance.A.whichB.it C.that D.this[點(diǎn)撥]

根據(jù)強(qiáng)調(diào)句型的判斷方法：將itis和that去掉后，此句成為Notwhoisrightbutwhatisrightisofimportance，是一個(gè)完整的句子，故此題是一個(gè)強(qiáng)調(diào)句型。[考例2]Idon’tmindhercriticizingme,but______ishowshedoesitthatIobjectto.A.it B.that C.this D.which[點(diǎn)撥]

去掉itis和that后，本句相當(dāng)于...,butIobjecttohowshedoesit，是個(gè)完整的句子。故此句是it強(qiáng)調(diào)句型，被強(qiáng)調(diào)部分是賓語從句。2.Withoutthe‘greenhouseeffect’,theearthwouldbeaboutthirty-threedegreesCelsiuscoolerthanitis.

如果沒有溫室效應(yīng)，地球會(huì)比現(xiàn)在冷33℃?！@是一個(gè)含蓄虛擬條件句

應(yīng)該注意有時(shí)假設(shè)的情況并不以條件從句形式表示出來，而是通過一個(gè)介詞短語或其他方式表示。常用的詞或短語有：without,butfor,butthat,otherwise,or,but等。e.g.Withoutyourhelp(=Ifwehadnothadyourhelp),wecouldnothavesucceeded.

要是沒有你的幫助，我們是不會(huì)成功的。e.g.

Butforelectricity(=Iftherewerenoelectricity),therewouldbenomodernindustry.

要是沒有電，就不會(huì)有現(xiàn)代工業(yè)。e.g.Hewashavingameetingwithhisstudents;otherwisehewouldhavecome.

他當(dāng)時(shí)正與他的學(xué)生進(jìn)行討論，否則的話他就來幫我們了。e.g.Hefeltverytiredyesterday,orhewouldhaveattendedtheparty.

他昨天很累,不然他就參加那個(gè)聚會(huì)了。3.ItwasascientistcalledCharlesKeelingwhomadeaccuratemeasurementsoftheamountofcarbondioxideintheatmospherefrom1957to1997.

是一位名叫查爾斯·奎林的科學(xué)家把

1957至1997年期間大氣層中二氧化碳的含量作了精確的統(tǒng)計(jì)。該句是一個(gè)itwas...who強(qiáng)調(diào)句。ascientistcalledCharlesKeeling是被強(qiáng)調(diào)部分，其中calledCharlesKeeling為過去分詞短語作后置定語，修飾ascientist。4.Ontheotherhand,therearethose,likeGeorgeHambley,whoareopposedtothisview,believethatweshouldnotworryabouthighlevelsofcarbondioxideintheair.

另一方面,還有一些人，對這一觀點(diǎn)持反對態(tài)度，像科學(xué)家喬治·漢布利，他們認(rèn)為我們不必?fù)?dān)心空氣中高含量的二氧化碳。該句是一個(gè)主從復(fù)合句。主句為therearethose，likescientistGeorgeHambley作句子的插入語，who引導(dǎo)的定語從句修飾those，且在該定語從句中其謂語動(dòng)詞believe又帶有that引導(dǎo)的賓語從句。句子的主要部分可以表示為:...therearethosewhobelievethat...ontheotherhand:usedtogiveanotheropinionorfactthatshouldbeconsideredaswellastheoneyouhavejustgiven

另一方面

alsoontheonehand...ontheotherhand

Iwanttogototheparty,butontheotherhandIoughttobestudying.

我想去參加聚會(huì)，但從另一方面來說，我應(yīng)該留下來學(xué)習(xí)。I.根據(jù)下列各句句意及所給單詞的首字母或漢語提示，寫出各單詞的正確形式。
