More Bad News 全球糧食危機(jī)

by Matthew Brown

Another global concern comes into view: a food shortage.

糧食短缺引起全球關(guān)注。

As if global financial and environmental crisis were not enough, another alarming problem has been developing in the past few years: the food crisis.

_(1)_ In poorer countries, it's an urgent problem, and some parts of the world have already been experiencing food riots. Food prices are an economic issue, and in economics there is usually a lot of disagreement about the causes of problems. Some of the main factors, though, may be as follows.

Weather might be the most significant issue when it comes to current food shortages. _(2)_ To make matters worse, these droughts and other bad weather may be linked with global warming. Another problem is ever-rising oil and energy costs. _(3)_ Emerging economies, countries that were poor but are becoming rich, are using more and more fuel and competing for available resources. As economies around the world change, there is more demand for expensive food such as beef. However, a 100-calorie piece of beef requires 700 calories' worth of grain to be produced. _(4)_ Efforts to make biofuel may also be to blame. Some people argue that it takes far more energy to grow grain to produce biofuel than we can get from the biofuel itself. _(5)_

The food shortage has people pretty worried, but it is only recently that the problem has come to popular attention. For now, most of us will just have to wait and see what kind of solutions might be possible.

(A) If the argument is correct, then perhaps the grain would be better used for food instead.

(B) Over the last few years, the prices of food staples such as wheat, corn, and rice have doubled or tripled.

(C) So this means that beef production uses a lot more grain to produce a lot less food.

(D) Modern farming techniques require a huge amount of energy, and energy is becoming very expensive.

(E) The combination of recent natural disasters, such as the tsunami in Asia and droughts in Australia, Africa, and Central America, has led to very poor crop yields.

原來(lái)如此

1. 第一題空格應(yīng)選 (B)

理由:

a. 空格前的段落說(shuō),好像全球的經(jīng)濟(jì)與環(huán)境危機(jī)還不夠多似的,過(guò)去幾年來(lái)(in the past few years)還有另一個(gè)令人擔(dān)憂的問(wèn)題逐漸成形,那就是糧食危機(jī)(the food crisis)。

b. 選項(xiàng) (B) 的句子則接著表示,過(guò)去幾年來(lái)(Over the last few years),小麥、玉米和稻米等糧食產(chǎn)品(food staples)的價(jià)格飆高至兩倍或三倍,延續(xù)空格前糧食危機(jī)的話題,且兩句中的 in the past few years 與 Over the last few years 亦相呼應(yīng),故為正選。

大補(bǔ)丸:

a. over/in/for/during + the last/past + (few/數(shù)字) + week(s)/month(s)/year(s)/decade(s)  過(guò)去……星期∕月∕年∕十年以來(lái)(到現(xiàn)在)

例: Video games have changed a great deal over the past ten years.

(電動(dòng)游戲過(guò)去 10 年來(lái)有很大的改變。)

b. staple n. 不可缺少的食物 ; 主食

c. double vi. 加倍

d. triple vi. 增至三倍

2. 第二題空格應(yīng)選 (E)

理由:

a. 空格前的句子表示,說(shuō)到近來(lái)的糧食短缺(food shortages),也許天氣就是最重要的因素。

b. 選項(xiàng) (E) 的句子進(jìn)一步說(shuō),結(jié)合近來(lái)的許多天災(zāi)(natural disasters),像是亞洲的海嘯與澳洲、非洲和中美洲的旱災(zāi),均導(dǎo)致作物收成不佳(poor crop yields),語(yǔ)意連貫。且空格后的主詞為 these droughts(這些旱災(zāi)),即指 (E) 項(xiàng)中的 droughts,形成關(guān)鍵詞,故 (E) 應(yīng)為正選。

大補(bǔ)丸:

a. combination n. 結(jié)合

b. disaster n. 災(zāi)害

natural disaster  天災(zāi)

c. tsunami n. 海嘯(= tidal wave)

d. drought n. 旱災(zāi)

e. lead to + N/V-ing  導(dǎo)致……

例: Lack of good study habits can lead to poor grades in school.

(不良的讀書習(xí)慣會(huì)導(dǎo)致學(xué)業(yè)成績(jī)不佳。)

f. yield  n. 產(chǎn)量

3. 第三題空格應(yīng)選 (D)

理由:

a. 空格前的句子說(shuō),另一個(gè)問(wèn)題是持續(xù)攀升的油價(jià)與能源價(jià)格(ever-rising oil and energy costs)。

b. 選項(xiàng) (D) 的句子則說(shuō),現(xiàn)代的務(wù)農(nóng)技術(shù)需要大量能源,而能源卻越來(lái)越昂貴(energy is becoming very expensive),語(yǔ)意連貫,且兩句均有關(guān)鍵詞 energy(能源),故選之。

大補(bǔ)丸:

a huge/large amount of + 不可數(shù)名詞  大量的……

a small amount of + 不可數(shù)名詞  少量的……

例: A large amount of smoke rose from the chimney.

(那個(gè)煙囪冒出了大量的煙。)

4. 第四題空格應(yīng)選 (C)

理由:

a. 空格前的句子說(shuō),生產(chǎn) 100 卡路里的牛肉(beef)需要消耗 700 卡路里的谷物(grain)。

b. 選項(xiàng) (C) 的句子則進(jìn)一步說(shuō)明,這表示牛肉的生產(chǎn)(beef production)是利用較多谷物(more grain)去制造少量食物,兩句均有關(guān)鍵詞 beef 與 grain,語(yǔ)意亦連貫,故選之。

5. 第五題空格應(yīng)選 (A)

理由:

a. 空格前的句子說(shuō),有些人爭(zhēng)論(argue)說(shuō),為了生產(chǎn)生化燃料而栽種作物所耗費(fèi)的能源,遠(yuǎn)遠(yuǎn)多過(guò)生化燃料能提供我們的量。

b. 選項(xiàng) (A) 的句子則說(shuō),如果這項(xiàng)論點(diǎn)(argument)屬實(shí),那么也許把谷物拿來(lái)當(dāng)食物反而比較理想,延續(xù)空格前關(guān)于制造生化燃料的話題,語(yǔ)意連貫,故選之。

大補(bǔ)丸:

a. argument n. 論點(diǎn)

b. grain n. 谷物

c. instead adv.(反)而,卻

例: She didn't do her homework; she chatted on the Net instead.

中文翻譯&標(biāo)準(zhǔn)答案

好像全球的經(jīng)濟(jì)與環(huán)境危機(jī)還不夠多似的,過(guò)去幾年來(lái),還有另一個(gè)令人擔(dān)憂的問(wèn)題逐漸成形,那就是糧食危機(jī)。

過(guò)去幾年來(lái),小麥、玉米和稻米等糧食產(chǎn)品的價(jià)格飆高至兩倍或三倍。在較窮困的國(guó)家,這是個(gè)迫切的問(wèn)題,而且世界上有些國(guó)家已經(jīng)因糧食短缺而發(fā)生暴動(dòng)。糧食價(jià)格是一項(xiàng)經(jīng)濟(jì)問(wèn)題,而在經(jīng)濟(jì)學(xué)上,對(duì)問(wèn)題的成因通常有很多不同的論點(diǎn)。不過(guò)主要的因素可概述如下。

說(shuō)到目前的糧食短缺,天氣或許是最重大的因素。結(jié)合近來(lái)的許多天災(zāi),像是亞洲的海嘯與澳洲、非洲、中美洲的旱災(zāi),均導(dǎo)致作物收成不佳。更糟的是,這些旱災(zāi)與其它壞天氣都或許與全球暖化有關(guān)。另一個(gè)問(wèn)題是持續(xù)攀升的油價(jià)與能源價(jià)格?,F(xiàn)代的務(wù)農(nóng)技術(shù)需要大量能源,而能源卻越來(lái)越昂貴。而原本貧窮但逐漸邁向富裕的新興國(guó)家,他們使用的能源越來(lái)越多,并且一同競(jìng)爭(zhēng)現(xiàn)有的資源。

正當(dāng)全球經(jīng)濟(jì)情勢(shì)改變,像牛肉等昂貴食物的需求也愈來(lái)越大。然而,生產(chǎn)一塊 100 卡路里的牛肉卻需要消耗 700 卡路里的谷物。這表示牛肉的生產(chǎn)是利用較多谷物去制造少量食物。致力于生產(chǎn)生化燃料也是罪魁禍?zhǔn)字?。有些人?zhēng)論說(shuō),為了制造生化燃料而栽種作物所耗費(fèi)的能源,遠(yuǎn)遠(yuǎn)超過(guò)生化燃料本身能提供給我們的能源。如果這項(xiàng)論點(diǎn)屬實(shí),那么也許拿谷物來(lái)當(dāng)食物反而比較理想。

糧食短缺使人們憂心忡忡,但這問(wèn)題直到最近才引起大眾的注意?,F(xiàn)在,大多數(shù)人也只能靜觀其變,看哪種解決方式才是可行的。
