havebeendrawing

Dr.Taylor’sattention.

這種令人著迷的蝴蝶一直吸引著泰勒博士的注意。havebeendoing是現(xiàn)在完成進(jìn)行時(shí)，“一直在做某事”，表示過去某時(shí)開始的某個(gè)動(dòng)作或狀態(tài)一直延續(xù)到現(xiàn)在，且還在進(jìn)行。常表示動(dòng)作的延續(xù)性、重復(fù)性及感情色彩等。e.g.Mr.SmithhasbeenlivinginLondonsince1995.史密斯先生自從1995年以來一直住在倫敦。（延續(xù)性）

Haveyoubeenmeetingherrecently?

你最近常見到她嗎？（重復(fù)性）

Who’s

beeneatingmyapples?

誰吃了我的蘋果？（感情色彩）drawone’sattention“吸引某人注意力”。e.g.Hetriestodrawourattentionto

thepainting.

他試圖把我們的注意力吸引到這幅畫上。2.Here,asmanyas230millionbutterfliesspendthewinter.

在這里，多達(dá)兩億三千萬只蝴蝶在這里過冬。as…as“和……一樣”，表示同級(jí)比較?；窘Y(jié)構(gòu)為as+adj./adv.+as。

e.g.Englishwordscanbeasshortasoneletter.

英語單詞可以短到只有一個(gè)字母。Thisfilmisasinterestingasthatone.這部電影和那部電影一樣有趣。Yourpenwritesassmoothlyastime.你的鋼筆書寫起來和我的一樣流暢。其否定形式為notas/so+adj.+as。e.g.Thisdictionaryisnotas/sousefulas

youthink.這本詞典不如你想象的有用。注意：as…as結(jié)構(gòu)中，使用形容詞或副詞的原形。as…as結(jié)構(gòu)用于肯定句或否定句，so…as只用于否定句中。3.Thebutterfliesthatreturntothesoutharethegreat-greatgrandchildrenofthebutterfliesthatleftforthenorth.

這些飛回南方的蝴蝶是春天飛往北方蝴蝶的曾曾子孫。

thatreturntothesouth和thatleftforthenorth都是定語從句。

leavefor“到，去；出發(fā)，前往”。e.g.Theywillleave

BeijingforGuangzhoutomorrow.他們明天要離開北京去廣州。

TheyleftforShanghaiyesterday.

他們昨天去上海了。4.Whentheybegintotravelnorthinspring,thefemaleslayeggs.

當(dāng)他們春天開始向北方飛行時(shí)，雌性蝴蝶產(chǎn)卵。

travel“遷徙”northadv.

，“向北方”。也可說：traveltothenorth，這時(shí)north是名詞。e.g.Scientistsstilldon’tunderstandhowbutterfliesknowwhentoflysouth.科學(xué)家們?nèi)匀徊幻靼缀鯓又篮螘r(shí)飛向南方。layeggs“產(chǎn)卵”lay的過去式和過去分詞為laid，現(xiàn)在分詞為laying。5.ButinMexico,peoplecutdownthetreesthatthebutterfliesneedtorestonbecausetheywantmorelandforfarming.

但是在墨西哥，人們砍伐了蝴蝶賴以棲息的樹木，因?yàn)樗麄冃枰嗟母亍utdown“砍伐”

e.g.Manytreeshadbeencutdown

sothatthesoilwaswashedaway.

許多樹木被砍伐了，結(jié)果土壤被雨水沖走。cutdown還有“削減”的意思。e.g.Wemustcutourexpensesdowninordertolivethroughthewholeyear.

我們必須減少消費(fèi)，以便度過全年。e.g.Doyourestanybettertoday?今天你休息得好點(diǎn)嗎？Don’tlethimrestuntilhepromisestogowithus.他不答應(yīng)跟我們一起去，就一直纏著他不讓他安生。Herestedahandontheman’sshoulder.他把一只手放在那人肩上。rest在本句中的意思是“暫停；停止”。還有“休息；安定下來；放心”的意思?，F(xiàn)在完成進(jìn)行時(shí)表示動(dòng)作從過去某一時(shí)間開始，一直延續(xù)到現(xiàn)在還未結(jié)束?，F(xiàn)在完成進(jìn)行時(shí)有時(shí)也可用來表示經(jīng)常的、反復(fù)的動(dòng)作?，F(xiàn)在完成進(jìn)行時(shí)(1)結(jié)構(gòu)：have/has+been+V-ing(2)與since或for引導(dǎo)的時(shí)間狀語連用；since后接動(dòng)作開始的時(shí)間，for后面接一段時(shí)間；對(duì)since或for引導(dǎo)的時(shí)間狀語提問時(shí)要用howlong

。(3)否定形式是在have/has后加not構(gòu)成，可縮寫為haven’t/hasn’t。(4)一般疑問句形式是將have/has提至主語前；肯定回答用“Yes,主語+have/has.”，否定回答用“No,主語+haven’t/hasn’t.”。e.g.a.-Howlonghaveyoubeendrawing?-Ihavebeendrawingfortwohours.b.-HowlonghasMariabeenplayingthepiano?-Shehasbeenplayingthepianosinceshewasfiveyearsold.c.Theyhaven’tbeenworkingsincelastmonth.d.-Hashebeenlivinghere?-Yes,hehas./No,hehasn’t.定語從句是在復(fù)合句中起定語作用，修飾名詞、代詞或整個(gè)主句的從句。被定語從句修飾的詞叫先行詞。引導(dǎo)定語從句的關(guān)系詞有關(guān)系代詞(that,which,who,whom,whose等)和關(guān)系副詞(where,when,why)。定語從句關(guān)系詞在定語從句中的作用：①連接主句和定語從句；②指代先行詞；③在定語從句中充當(dāng)一定的成分。(1)關(guān)系代詞that與which在定語從句中，關(guān)系代詞that既可指人，也可指物，which一般用于指物。在指物時(shí)，二者一般可以互換，但非限制性定語從句中多用which引導(dǎo)。e.g.Theoldtownhasnarrowstreetsandsmallhousesthatarebuiltclosetoeachother.Thatevening,whichIwilltellyoumoreaboutlater,Iendedupworkingverylate.

(2)關(guān)系代詞who與whomwho指人，是主格，在定語從句中作主語，一般可用that替換。whom指人，是賓格，在定語從句中作賓語。在口語和非正式文體中可用who或that替換，也可以省略。e.g.Aftertheflooding,peopleweresufferinginthatarea,whourgentlyneededcleanwater,medicineandsheltertosurvive.

(3)關(guān)系代詞whosewhose是who的所有格，在定語從句中作定語，起限定作用。whose引導(dǎo)定語從句時(shí)，先行詞可指人，也可指物。e.g.IwishtothankProfessorSmith,withoutwhosehelpIwouldneverhavegotthisfar.關(guān)系副詞的用法引導(dǎo)定語從句的關(guān)系副詞主要有when,where,why等，它們?cè)趶木渲蟹謩e充當(dāng)時(shí)間狀語、地點(diǎn)狀語和原因狀語等。e.g.Weliveinanagewhenmoreinformationisavailablethaneverbefore.Iwalkeduptothetopofthehillwithmyfriends,whereweenjoyedabeautifulviewofthelake.

特殊先行詞后的定語從句(1)先行詞way后的定語從句way后跟有定語從句，且定語從句中缺少狀語時(shí)，定語從句通常由inwhich或that引導(dǎo)，也可以省略。e.g.Idon’tunderstandtheway(inwhich/that)theyworkedouttheproblem.(2)先行詞reason后的定語從句reason為先行詞時(shí)，如果定語從句中缺少狀語，則常用why或forwhich引導(dǎo)；如果定語從句中缺少賓語，則常用that或which引導(dǎo)，也可以省略。e.g.Canyoutellmethereasonwhyhewaslate?Canyoutellmethereason(that/which)hetoldyou?(3)有些先行詞雖不表示具體的地點(diǎn)，但表達(dá)一種“地步、境地、形勢(shì)”等抽象概念，position,situation,case,stage,point等，且關(guān)系詞在定語從句中作狀語，則用where來引導(dǎo)。先行詞為occasion時(shí)，一般要用when引導(dǎo)。e.g.Salesdirectorisapositionwhere
