答案與題解:

1.E本段的第三句點(diǎn)出了methane’sheat-trappingpowerintheatmosphereis21timesstrongerthancarbondioxide。

2.F本段要表達(dá)的中心意思是:livestock排出的甲烷也是溫室效應(yīng)的一個(gè)主要源頭。

3.C本段表達(dá)的重點(diǎn)是用but轉(zhuǎn)折的段后兩句。

4.D本段從科學(xué)的角度分析反芻動(dòng)物為什么會(huì)釋放出甲烷。

5.A選A的依據(jù)在第一段的第二句和昀后一句。

6.B選B的依據(jù)在第三段的第二句、第三句和第四段的第一句。這三個(gè)句子先后介紹了下列觀點(diǎn):沒有溫室氣體,生物不能生存;人類燃燒能源,加劇溫室效應(yīng);大氣甲烷含量增加一倍。7.F第四段第二句直接談到這個(gè)問題。人們常常將不斷加劇的溫室效應(yīng)歸罪于大工業(yè)和汽車,而cattle釋放甲烷的因素被忽略了。

8.E選項(xiàng)E是本文沒有提到的內(nèi)容,也就是說,其他五個(gè)選項(xiàng)的內(nèi)容文章部有涉及。

第十二篇一種強(qiáng)烈的溫室氣體

甲烷是一種無色無味的氣體,同時(shí)也是一種很強(qiáng)烈的溫室氣體,一旦釋放到空氣中,就會(huì)吸收地球表面散發(fā)的熱量。所以說甲烷是使這個(gè)星球日趨變暖(或叫全球變暖)的一個(gè)主要原因。按分子與分子對(duì)比,甲烷在大氣中吸收熱量的能力是二氧化碳——昀豐富的溫室氣體的21倍。

由于全世界有130億頭牛幾乎在連續(xù)不斷地打嗝(僅美國就有一億頭),難怪由牲畜釋放的甲烷就成為了一種主要的全球性甲烷來源。其他主要的甲烷來源有:石油、鉆井、采煤、固體垃圾以及沼澤地。

甲烷和二氧化碳等溫室氣體只占地球大氣的一小部分,大氣中78%為氮?dú),將?1%為氧氣。如果沒有溫室氣體來吸收太陽的熱量,使地球變暖,我們所知道的生命就不會(huì)存在。但在過去的200年里,通過燃燒油、天然氣和煤來獲取能量的人類活動(dòng)加劇了溫室效應(yīng)。

在過去的兩個(gè)世紀(jì)里,甲烷在大氣中的濃度地加了一倍多,人們常常將此歸罪于大工業(yè)和汽車。但是農(nóng)業(yè)在其中也扮演了一個(gè)重要角色。僅在過去40年里,全球牲畜數(shù)量就翻了一番。

牛吃的大部分是草,但卻長得身高體壯。原因何在?在于它們都長有瘤胃。它們的瘤胃容納160升的食物,養(yǎng)育數(shù)十億的微生物。這些微小的細(xì)菌和原生動(dòng)物可分解纖維素,形成可吸收的營養(yǎng)。沒有這些微生物牛就無法生存。由于微生物可吸收纖維素,所以就會(huì)釋放出甲烷。所有長有瘤胃的動(dòng)物(比如牛、綿羊和山

羊)都會(huì)這樣,因此它們經(jīng)常釋放出氣體。這是它們的正常吸收過程的一部分。它們反芻時(shí),就會(huì)將食物重新咀嚼,于是就釋放出氣體。一般每頭牛每天會(huì)排出600升甲烷。

因此,我們認(rèn)為,牲畜釋放的氣體也是全球變暖的一個(gè)主要因素。

答案與題解:

1.E本段談及糧食需求以每年2.5%的速度遞增,所以,農(nóng)業(yè)研究資金的投入至關(guān)重要。

2.A本段引用了費(fèi)舍的觀點(diǎn),如果能進(jìn)行農(nóng)業(yè)研究,在本世紀(jì)第一個(gè)25年中,即使世界人口從58億增加到80億,糧食供應(yīng)的格局和現(xiàn)在大致相同或有所改善。

3.C本段指出,農(nóng)業(yè)研究的資金投入還要增加。

4.B本段的中心思想是提高農(nóng)作物的單位面積產(chǎn)量。過去30年的實(shí)踐證明提高單位面積產(chǎn)量是可能的。

5.D本題答案的依據(jù)是第一段第二句的后半句:…withmoderntechnologiesandthedevelopmentofnewones,theworldshouldbeabletostayahead.

第九篇需要進(jìn)行更多的農(nóng)業(yè)研究

如果世界人民想比現(xiàn)在吃得更好,農(nóng)業(yè)研究資金的投入至關(guān)重要。農(nóng)業(yè)科學(xué)家托尼·費(fèi)舍說過需求每年增長2.5%,但由于有了現(xiàn)代技術(shù)和新技術(shù)的開發(fā),世界應(yīng)該能夠不斷前進(jìn)。他說:“要想在減少營養(yǎng)不良和貧困方面取得巨大的進(jìn)步,就必須扭轉(zhuǎn)全球?qū)H農(nóng)業(yè)研究投入下滑的趨勢!

解決糧食生產(chǎn)、土地貧瘠化和環(huán)境污染問題,必須進(jìn)行研究。穩(wěn)定的當(dāng)?shù)丶Z食供應(yīng)可以促進(jìn)經(jīng)濟(jì)地長,放慢人口地長速度。費(fèi)舍博士描繪說,世界有能力在人口由58億增加到80億的頭25年實(shí)現(xiàn)糧食供應(yīng)充足。情況很可能保持現(xiàn)狀或有所改善,但仍會(huì)有大批人口處于饑餓當(dāng)中。2020年貧窮和饑餓人口昀大集中地為撒哈拉以南的非洲部分和南亞,這與目前情況類似。如果有什么變化的話,也只是在南亞有稍微的改善,而不是在撒哈拉以南的非洲。主要改善地區(qū)將是東亞、南美和東南亞。

發(fā)展中國家每年將農(nóng)業(yè)國內(nèi)生產(chǎn)總值的大約0.5%(80億美元)用于研究,發(fā)達(dá)國家則用2.5%的國內(nèi)生產(chǎn)總值進(jìn)行研究。費(fèi)舍博士說所有國家都需要更多的資金。他說糧食研究會(huì)開發(fā)出新技術(shù),這些新技術(shù)又會(huì)傳播到許多國家,例如小麥生產(chǎn)研究的成果已經(jīng)在墨西哥、

中國或印度得到應(yīng)用。他說:“技術(shù)仍需因地制宜進(jìn)行改進(jìn),但許多戰(zhàn)略性研究可以在全球應(yīng)用,所以可以

非常有效地利用財(cái)力!痹谶^去30年中,大米、小麥和玉米的產(chǎn)能大幅度地增長,尤其是在發(fā)展中國家,例如,1950年到1995年,玉米產(chǎn)量由每公頃2噸均加到每公頃8噸。但是,推動(dòng)高產(chǎn)的技術(shù),比如高產(chǎn)新品種、化肥以及灌溉,正在消耗殆荊費(fèi)舍博士說:“如果你想騰出土地做非農(nóng)業(yè)用途,保護(hù)森林和野生動(dòng)物,就必須提高單位面積產(chǎn)量!
