1.Passage FourThe atmosphere and oceans are not the only parts of the environment being damaged. Rain forests are being quickly destroyed as well, and their survival is questionable. E. O. Wilson, a biologist at Harvard, calls the depletion(枯竭、耗尽)of rain forest areas "the greatest extinction since the end of the age of dinosaurs(恐龙)."Unlike some environmental issues, rain forests' depletion has fortunately received significant public and media's attention. Despite the opposition to the cutting down of rain forests, the problem continues. Every year, Brazil chops down an area of forests the size of the state of Nebraska. In addition to the Amazon's rain forests, many other forests are being cut down as well.: In Indonesia, Zaire, Papua-new Guinea, Malaysia, Burme, the Philippines, Peru, Colombia, Bolivia, and Venezuela, rain forests that were once great have been lost.According to some estimates, 50 million acres of rain forest are cut down every year. The United Nations says the figure is closer to 17 million acres. The World Wildlife Fund says that every minute,25 to 50 acres are cut down or burnt to the ground.The world's growing population has been a primary reason of rain forests' destruction. More people need land to live on and wood products to consume. Limiting population growth may be the first in a series of steps that would alleviate the destruction of the rain forests.48. In the opinion of the author, ______are being destroyed terribly at present.A. the oceansB. the atmosphereC. the rain forestsD. all the above

    How Technology Pushes Down Prices

    1 Prices have fallen in the food business because of advances in food production and distribution tech-
    nology.Consumers have benefited greatly from those advances.People who predicted that the world would
    run out of food were wrong. We are producing more and more food with less and less capital.Food is there-
    fore more plentiful and cheaper than it has ever been.Spending on food compared with other goods has fallen
    for many years,and continues to drop.
    2 Supermarkets have helped push down prices mainly because of their scale.Like any big business,
    they can invest in IT systems that make them efficient. And their size allows them to buy in bulk.As super-
    markets get bigger,the prices get lower.
    3 Huge retail companies such as Wal-Mart have tremendous power and they can put pressure on pro-
    ducers to cut their margins.As a result,some producers have had to make cuts.In recent years,Unilever
    has cut its workforce by 33,000 to 245,000 and dropped lots of its minor brands as part of its"path to
    growth"strategy.Cadbury has shut nearly 20 per cent of its 133 factories and cut 10 per cent of its 55,000
    global workforce.These cuts help keep costs down,and the price of food stays low.
    4 Does cheap food make people unhealthy?Cheap food may encourage people to eat more.Food corn-
    panies certainly think that giving people more food for their money makes them buy more.Giving people bigger
    portions is an easy way of making them feel they have got a better deal.That is why portions have got larger
    and larger. In America,soft drinks came in 80z(225 g)cans in the past,then 120z(350g),and now
    come in 200z(550g)cans.If a company can sell you an 80z portion for$7,they can sell you a 120z
    portion for$8.The only extra cost to the company is the food,which probably costs 25 cents.
    5 Now companies are under pressure to stop selling bigger portions for less money.But it is hard to
    change the trend.

    Paragraph 3 ___________
    A:Huge Retailers Force Producers to Cut Costs
    B:Consumers Like Supermarkets
    C:Technology Helps Reduce Food Prices
    D:Food Comes Cheaper in Larger Portions
    E:Chain Stores Provide Better Service
    F:Bigger Sunermarkets Offer Lower Prices

    答案：A
    解析：
    文章第一段的主题句是第一句。这段主要讲食物价格下降的原因是生产和分配技术 的发展。
    文章第二段主要讲的是超级市场因为规模大，能引进先进技术，故能提供低价格的 商品。
    由文章第三段主题句“Huge retail companies...can put pressure on producers to cut theirmargins.”可知，超级零售商能迫使生产商降低商品价格。
    文章第四段讲的是，食品公司给顾客提供每份量大的商品，能很容易使顾客感觉到他 们得到了一个大的折扣，这样顾客会买更多的商品。因此每份量大的食品价格便宜。
    文章第二段提到“And their size allows them to buy in bulk.”其中in bulk = in large quantities。
    文章第三段提到“As a result, some producers have had to make cuts."make cuts的意思 是“降价”。
    文章第三段提到“Unilever...dropped lots of its minor brands...”由此可知答案为F。
    文章第四段提到“Giving people bigger portions is an easy way of making them feel they have got a better deal.”其中a better deal = a good bargain。

    How Technology Pushes Down Prices

    1 Prices have fallen in the food business because of advances in food production and distribution tech-
    nology.Consumers have benefited greatly from those advances.People who predicted that the world would
    run out of food were wrong. We are producing more and more food with less and less capital.Food is there-
    fore more plentiful and cheaper than it has ever been.Spending on food compared with other goods has fallen
    for many years,and continues to drop.
    2 Supermarkets have helped push down prices mainly because of their scale.Like any big business,
    they can invest in IT systems that make them efficient. And their size allows them to buy in bulk.As super-
    markets get bigger,the prices get lower.
    3 Huge retail companies such as Wal-Mart have tremendous power and they can put pressure on pro-
    ducers to cut their margins.As a result,some producers have had to make cuts.In recent years,Unilever
    has cut its workforce by 33,000 to 245,000 and dropped lots of its minor brands as part of its"path to
    growth"strategy.Cadbury has shut nearly 20 per cent of its 133 factories and cut 10 per cent of its 55,000
    global workforce.These cuts help keep costs down,and the price of food stays low.
    4 Does cheap food make people unhealthy?Cheap food may encourage people to eat more.Food corn-
    panies certainly think that giving people more food for their money makes them buy more.Giving people bigger
    portions is an easy way of making them feel they have got a better deal.That is why portions have got larger
    and larger. In America,soft drinks came in 80z(225 g)cans in the past,then 120z(350g),and now
    come in 200z(550g)cans.If a company can sell you an 80z portion for$7,they can sell you a 120z
    portion for$8.The only extra cost to the company is the food,which probably costs 25 cents.
    5 Now companies are under pressure to stop selling bigger portions for less money.But it is hard to
    change the trend.

    Some food producers have reduced__________.
    A:their workforce
    B:huge portions
    C:large quantities
    D:their money
    E:a good bargain
    F: minor brands

    答案：D

    文章第一段的主题句是第一句。这段主要讲食物价格下降的原因是生产和分配技术 的发展。
    文章第二段主要讲的是超级市场因为规模大，能引进先进技术，故能提供低价格的 商品。
    由文章第三段主题句“Huge retail companies...can put pressure on producers to cut theirmargins.”可知，超级零售商能迫使生产商降低商品价格。
    文章第四段讲的是，食品公司给顾客提供每份量大的商品，能很容易使顾客感觉到他 们得到了一个大的折扣，这样顾客会买更多的商品。因此每份量大的食品价格便宜。
    文章第二段提到“And their size allows them to buy in bulk.”其中in bulk = in large quantities。
    文章第三段提到“As a result, some producers have had to make cuts."make cuts的意思 是“降价”。
    文章第三段提到“Unilever...dropped lots of its minor brands...”由此可知答案为F。

    正确答案： A
    解析：
    文段的主要意思是：随着科技的发展，越来越多的垃圾和废物得以循环开发和重新利用，更多副产品得以创造出来，因此那些认为自然资源会枯竭的说法已经不是现实，而且禁止进入濒危动物自然保护区的做法也已经没有必要；题目要求选出会削弱文段论点的选项，即与文意相悖的选项，分析可知，A项指出人们每年回收利用的自然资源和材料只是消耗的十分之一，说明大部分资源没有得以有效利用，与文章立意不符，符合要求；B、C两项的内容与文章无关；D、E两项均与文意相符，不符合要求。因此，正确答案为A项。

    Installing exhaust filters on all trucks and buses.

    B

    Better managing forest fires.

    C

    Getting Americans to give up SUVs.

    D

    Melting snow and ice.


    正确答案： D
    解析：
    soot指“烟灰”。录音中提到“…reducing the amount of soot in the air by…better managing forest fires is probably easier than getting Americans to give up SUVs”，其中SUV指“多功能车”，可见减少烟灰最好的方法之一是更好地对森林火灾进行管理。
    【录音原文】
    Because soot promotes the melting of snow and ice, it may exacerbate the problem of rising seas. The good news is that reducing the amount of soot in the air by installing exhaust filters on diesel trucks and buses and better managing forest fires is probably easier than getting Americans to give up SUVs. Fires are the source of about half the world’s soot.
