Question

【題目】 Modern agriculture and its ability to feed billions of people may be among humanity’s greatest successes. However, it comes with hidden costs. For example, have you ever considered how much water is needed to provide you with a steak or a salad? It may surprise you.

In a recent study published in the journal Nutrients, scientists from the Commonwealth Scientific and Industrial Research Organization(CSIRO), Australia's national science organization, took a close look at the diets of 9,341 adult Australians—specifically, their “water-scarcity footprints(水消耗足跡)”.

It turned out that a sweet tooth not only adds to our waistlines(腰圍) but also stresses our water resources. The water-scarcity footprint is a widely recognized measurement of water consumption. First, it counts the liters of water you used. Then, it looks at the place where the water was used. The more lacking water is in your area, the larger your water-scarcity footprint.

The scientists found that the average Australian's diet had a water-scarcity footprint of 362 liters per day. Snacks—cookies, cakes and alcohol—accounted for 25 percent of the water-scarcity footprint. The research also included a glass of wine(41 liters), a single serving of potato chips(23 liters), and a small bar of milk chocolate(21 liters).

Not surprisingly, cutting out snacks would be the N0.1 priority if you wanted to lower your own water-scarcity footprint.

Earth's surface is 70 percent water, but only 2.5 percent of that can be used for drinking or farming. By 2030, a world of about 8.6 billion people will need 35 percent more water, 40 percent more energy, and 50 percent more food, according to the United States National Intelligence Council. So, we need to watch what we eat, not just for our personal health but for the health of our societies.

【3】What does the underlined part “the N0.1 priority” in Paragraph 5 probably mean?

A.the least important thingB.the least impossible thing

C.something to be done firstD.something to be prevented first

【4】What does the last paragraph intend to tell us?

C.Make good use of energy.D.Produce more healthy food.

Answer 1

【答案】

【1】D

【2】D

【3】C

【4】A

【解析】

這是一篇說明文。文章主要講了現(xiàn)代農(nóng)業(yè)雖然養(yǎng)活數(shù)十億人，但是它也帶來了隱藏的成本。水消耗足跡是一種被廣泛認可的衡量水消耗的指標，一項關(guān)注于水消耗足跡的研究表明，你所在的地區(qū)缺水越嚴重，你的水消耗足跡就越大。且餅干、蛋糕和酒精等零食造成了25%的水消耗足跡。因此我們應(yīng)該注意我們的飲食。

【1】細節(jié)理解題。根據(jù)第二段In a recent study published in the journal Nutrients, scientists from the Commonwealth Scientific and Industrial Research Organization(CSIRO), Australia's national science organization, took a close look at the diets of 9,341 adult Australians—specifically, their “water-scarcity footprints(水消耗足跡)”.可知澳大利亞國家科學(xué)組織聯(lián)邦科學(xué)與工業(yè)研究組織的科學(xué)家最近在《營養(yǎng)》雜志上發(fā)表了一項研究，他們仔細研究了9341名澳大利亞成年人的飲食——特別是他們的“水消耗足跡”。由此可知，最近的研究關(guān)注的是水消耗足跡。故選D。

【2】細節(jié)理解題。根據(jù)第三段中The more lacking water is in your area, the larger your water-scarcity footprint.可知你所在的地區(qū)缺水越嚴重，你的水消耗足跡就越大。由此可知，CSIRO的科學(xué)家在他們的研究中發(fā)現(xiàn)了所在地區(qū)缺水意味著更大的水消耗足跡。故選D。

【3】詞義猜測題。根據(jù)第四段中Snacks—cookies, cakes and alcohol—accounted for 25 percent of the water-scarcity footprint. The research also included a glass of wine(41 liters), a single serving of potato chips(23 liters), and a small bar of milk chocolate(21 liters).可知餅干、蛋糕和酒精等零食造成了25%的缺水足跡。研究還包括一杯葡萄酒（41升），一份薯片（23升）和一小塊牛奶巧克力（21升）。由此可知，如果你想降低自己的水消耗足跡，減少零食將是首先要做的事情。故劃線短語“the N0.1 priority”意思為“首先要做的事情”。故選C。

【4】推理判斷題。根據(jù)最后一段中So, we need to watch what we eat, not just for our personal health but for the health of our societies.可知所以，我們需要注意我們吃什么，不僅是為了我們個人的健康，也是為了我們整個社會的健康。由此可推知，最后一段想告訴我們注意我們的飲食。故選A。
