答案與題解:
1.A通篇文章都在敘述禿鷹瀕臨滅種對(duì)印度環(huán)境的負(fù)面影響,而且文章的標(biāo)題中的"dying vultures"也提供了線索。decline符合上下文的意思,是答案。rise與上下文的意思相反。sharp teeth和sharp eyes是禿鷹的特點(diǎn),但文章并未提及。
2.C禿鷹瀕臨滅亡,給環(huán)境帶來(lái)問(wèn)題。上一句的"alarm rather than celebration"提供了解題的線索,禿鷹瀕臨滅亡對(duì)我們是一種警告,而不是一件值得慶賀的事。選problem是合適的。至于debate和solution,文章并未涉及。
3.B禿鷹數(shù)量的減少對(duì)當(dāng)?shù)鼐用袷且环N災(zāi)難。此外,對(duì)誰(shuí)也是一種災(zāi)難呢?as引出的對(duì)象是誰(shuí)呢? 這個(gè)對(duì)象不會(huì)是humans,plants或cows。答案是birds。
4.D作者原來(lái)的用詞一定是across the Indian sub-continent(整個(gè)印度次大陸),不可能是 over the Indian sub-continent(在印度次大陸上空),with the Indian sub-continent(與印度次大陸一起)或 through the Indian sub-continent(穿越印度次大陸)。
5.B本段前面的句子描述了禿鷹在保護(hù)該地區(qū)的環(huán)境上作用很大,所以禿鷹不會(huì)是時(shí)有時(shí)無(wú)(sometimes)地起作用,或突然地(suddenly)起作用,或幾乎不(hardly)起作用。只有選long(長(zhǎng)期以來(lái)一直)起作用才合乎上下文的意思。
6.C為什么禿鷹會(huì)起保護(hù)環(huán)境的作用呢?本段的下半段說(shuō)出了其中的原因。牛在印度被視為神物,死后露尸戶(hù)外,任其腐爛。禿鷹以食牛的尸體為生,同時(shí)也清除了污染源,保護(hù)了城鎮(zhèn)和鄉(xiāng)村的環(huán)境。這些句子講的是原因,所以選擇because是對(duì)的。
7.A文章說(shuō)每年有成千上萬(wàn)頭牛死亡并露尸城鎮(zhèn)和鄉(xiāng)村。既然是這樣,就不會(huì)是偶爾(occasionally)或可能(possibly)或最終(finally)露尸在城鎮(zhèn)和鄉(xiāng)村。露尸戶(hù)外是印度的傳統(tǒng),所以traditionally是答案。
8.D 本段第一句表達(dá)的是因果關(guān)系。The disappearance of the vultures 是因,an explosion in the numbers of wild dogs feeding on the remains of these dead animals 是果。四個(gè)選項(xiàng)中只有l(wèi)ed to (導(dǎo)致)能表達(dá)這種因果關(guān)系,所以led to是答案。
9.B野狗是狂犬病菌的主要攜帶者,野狗大量的出現(xiàn)當(dāng)然會(huì)增加狂犬病擴(kuò)散的危險(xiǎn)性,而不是相反。所以選increase是正確的,而drop是increase的反義詞,不會(huì)是答案。change或disappear都脫離了上下文的意思,所以不是答案。
10.A狂犬病從野狗傳到人身上已經(jīng)非?膳,如果再傳到其他動(dòng)物身上問(wèn)題就更嚴(yán)重了。 四個(gè)選項(xiàng)中,選future構(gòu)成詞組in the future(在未來(lái))符合上下文的意思。
11.B從后面的"an emergency project has been launched(啟動(dòng)了應(yīng)急項(xiàng)目)"可以推斷出要選的形容詞是urgent(緊迫的)。
12.D啟動(dòng)應(yīng)急項(xiàng)目是為了找到一個(gè)解決的辦法。neglect a solution,use a solution或remove a solution顯然不符合上下文的意思。find是答案。
13.C本段說(shuō)禿鷹的數(shù)量急劇減少,已被列為瀕危物種。本題的選項(xiàng)cures(治療法)、 arrivals(到達(dá))或 journeys(旅程)與本段后面一句 "All three species are now listed as 'critically endangered'"所表達(dá)的意思接不上。選deaths,全段的意思就連貫了。因此, deaths是答案。
14.D在四個(gè)選項(xiàng)中,along,on,in明顯不合適。by有"到(某事物)的程度"的意思。"...the three species of vultures had declined by over 90 per cent" 的意思是"三種秀鷹的數(shù)量減少了90%以上"。
15.A 花費(fèi)或用多少時(shí)間英語(yǔ)的常用的表達(dá)法是"take...days/months,etc."。選take是正確的。其他三個(gè)選項(xiàng)都不合適。
參考譯文
第八篇印度為什么需要瀕臨滅亡的禿鷹
人們談?wù)摰亩d鷹可能看起來(lái)既丑又危險(xiǎn),但是印度三種禿鷹瀕臨滅亡對(duì)我們是一種警告,而不是一件值得慶賀的事。它向世人明示了一個(gè)新的環(huán)境問(wèn)題。禿鷹數(shù)量的急劇減少不僅是這些鳥(niǎo)類(lèi)的災(zāi)難對(duì)當(dāng)?shù)鼐用裢瑯右彩侨绱,它同時(shí)給整個(gè)印度次大陸帶來(lái)了公共衛(wèi)生問(wèn)題。
雖然禿鷹的名聲不好,許多印度人也討厭其長(zhǎng)相,但是長(zhǎng)久以來(lái),禿鷹在維護(hù)全印度的城鎮(zhèn)和鄉(xiāng)村的清潔方面扮演了非常重要的角色。因?yàn)槎d鷹是以死牛為生。在印度,每年都有成千上萬(wàn)的牛死去,而牛是神圣的動(dòng)物,死后露尸戶(hù)外,任其腐爛。
禿鷹的消失使得以牛尸為生的野狗數(shù)量暴增,因此,人們擔(dān)心罹患狂犬病的病人會(huì)增加。由于野狗是狂犬病的主要攜帶者,這種可怕的疾病最終會(huì)影響當(dāng)?shù)氐木用。狂犬病也可能傳播到其他生物,未?lái)會(huì)導(dǎo)致更大的問(wèn)題。
采取行動(dòng)刻不容緩。所以,一個(gè)危機(jī)處理項(xiàng)目已經(jīng)啟動(dòng),目的是找到解決禿鷹問(wèn)題的方法?茖W(xué)家們正試圖確認(rèn)導(dǎo)致禿鷹死亡的疾病,如果可能的話(huà),找到治愈該病的方法。
在印度,人們注意到禿鷹的大批死亡最早是在20世紀(jì)80年代。根據(jù)當(dāng)時(shí)的物種調(diào)查顯示,三種禿鷹的數(shù)量減少了90%以上。目前,這三種禿鷹都被列為"極度瀕危動(dòng)物' 由于大部分禿鷹每次只產(chǎn)一只蛋,幼鷹需要大約5年的時(shí)間才能成熟,因此,若想遏制住禿鷹數(shù)量的下降會(huì)是一項(xiàng)長(zhǎng)期的、艱巨的任務(wù)。
