10.Food production does great harm to our environment.There are many procedures involved in the manufacture of food that result in greenhouse gases and other pollutants.Some procedures require the consumption of large amounts of fossil fuels,such as the transportation and storage of food products.Other factors that cause great damage to our environment include the overuse of fresh water.
The production of beef is more damaging to the environment than that of any other food we consume,Raising large numbers of cattle requires the production of large amounts of food for the animals.It's estimated that producing one pound of beef requires seven pounds of feed.
Land use is also a problem.If the cattle are free-range cattle,large areas of land are required for them to live on.This has led to disastrous forest cutting and the loss of rare plants and animal species,particularly in tropical rain forests in Central and South America.
Another problem specific to beef production is methane emissions(甲烷排放).Although many people are aware of the damaging effects of carbon dioxide,they don't realize methane's global warming potential is 25times worse,making it a more dire problem.
Unfortunately,beef consumption is growing rapidly.This is the result of simple supply and demand factors.Specifically,there are two main causes of demand that are encouraging the production of more supply.First,the increase in the world population means there are more people to consume meat.The second factor is socioeconomic advancement.As citizens in developing nations become financially stable,they can afford to buy more meat.
Therefore,one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.

分析 本文講述了生產牛肉給環(huán)境帶來的危害,希望可以使人們降低牛肉的消費.
解答 32.C.細節(jié)理解題.由第二段The production of beef is more damaging to the environment than that of any other food we consume可知,生產牛肉特別損害環(huán)境,故選C.
33.A.詞義猜測題.由前一句Although many people are aware of the damaging effects of carbon dioxide,they don't realize methane's global warming potential is 25times worse,雖然很多人都知道二氧化碳的破壞性影響,但是他們沒有意識到甲烷的全球變暖潛能是二氧化碳的25倍,這是一個更可怕的事情,故選A.
34.A.細節(jié)理解題.由倒數第二段the increase in the world population means there are more people to consume meat,可知人口的增長導致需要更多的牛肉,故選A.
35.D.主旨歸納題.由最后一段one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.可知作者希望可以使人們降低牛肉的消費來減少溫室氣體排放,故選D.
點評 本篇文章主要是細節(jié)理解方面的題型,需要考生通過跳讀迅速找到對應的句子進行詳細理解,句子的理解可以結合上下文意思,通過邏輯推理得到.
