Why Buy Shade-Grown Coffee?
When people argue about whether coffee is good for health,they're usually thinking of the health of the coffee drinker. Is it good for your heart?Does it increase blood pressure?Does it help you concentrate?However,coffee affects the health of the human population in other ways, too.
Traditionally, coffee bushes were planted under the canopy(树冠)of taller indigenous(土生土长的)trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees.At first,this increases production because more coffee bushes can be plan-ted if there aren't any trees.With increased production come increased profits.
Unfortunately,deforesting for coffee production immediately decreases local wildlife habitat. Native birds nest and hide from predators(捕食者)in the tall trees and migrating birds rest there.
Furthermore,in the long term,the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee.The fertilizers and pesti- cides kill insects that eat coffee plant,but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.
Fortunately,farmers in Central and South America are beginning to grow more coffee bushes in the shade .We can support these farmers by buying coffee with such labels as"shade grown" and"bird friendly."Sure,these varieties might cost a little more.But we're paying for the health of the birds,the land,ourselves,and the planet. I think it's worth it.

The full-sun method may affect the following EXCEPT______.
A: insects
B: air
C: birds
D: humans

参考答案和解析
答案:B
解析:
主旨大意题。文章首段提出咖啡对人类健康的影响,紧接着三段讲述全日照咖啡对生态环境的破坏,最后一段讲述美国中部和南部的农民在树荫下种植咖啡,引出文章主旨,并鼓励人们买这种咖啡。因此本题选D。
文章由传统(traditionally)种植咖啡的方法(full-sun method)发展到现在种植咖啡的方法(shade-grown),显而易见,traditionally是用来展示咖啡种植的变化。
由文章第二段中的“At first, this increases production... With increased production come increased profits.”可知,全日照咖啡的增产带来了更高的利润。故本题选D。
根据第二段中的“However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees.”可知,农民们通过砍伐森林来获得更多的土地。
文章第四段提到了全日照咖啡种植的影响,包括对昆虫,鸟,其他动物,水,甚至人类的影响,但并没有提到对空气的影响。因此选择B。

    Caffeine

    Caffeine is probably the most widely used drug in the world.Humans have been consuming caffeine for
    hundreds of years,primarily in the form of coffee,tea,and cocoa. Habitual coffee and tea drinkers had long
    been observed to have a lower incidence of non-melanoma(黑色素瘤)skin cancers , although no one knew
    why.A recent study found that caffeine affects skin cells damaged by ultraviolet radiation,a main cause of
    skin cancer. Caffeine interferes with a protein that cancerous cells need to survive,leaving the damaged cells
    to die before they become cancerous. Drinking caffeinated coffee has also been associated with a decreased
    incidence of endometrial(子宫内膜的)cancer-that is , cancer of the cells lining the uterus. The strongest
    effect appears to be in overweight women,who are at greatest risk for the disease.Researchers believe blood
    sugar,fat cells,and estrogen(雌性激素)may play a role. Although the mechanism remains unknown,peo-
    pie who drink more than two cups of coffee or tea a day reportedly have about half the risk of developing
    chronic liver disease as those who drink less than one cup of coffee daily;caffeinated coffee has also been as-
    sociated with lowered risk of cirrhosis(肝硬化)and liver cancer.
    While many of caffeine's undesirable effects,such as elevated heart rate and blood pressure,are brief,
    some short-term benefits,including pain relief,increased alertness,and increased physical endurance,have
    also been attributed to caffeine.As a component of numerous over-the-counter diet pills and pain relievers,
    caffeine increases their effectiveness and helps the body absorb them more quickly. By constricting(收缩)
    blood vessels in the brain , it can alleviate headaches一even migraines(偏头痛)一and can help counter the
    drowsiness(眩晕)caused by antihistamines(抗组胺药).
    Caffeine does not alter the need for sleep,but it does offer a temporary solution to fatigue for people who
    need to stay alert. Research has shown that sleep-deprived individuals who consumed caffeine had improved
    memory and reasoning abilities,at least in the short term. Studies of runners and cyclists have shown that
    caffeine can improve their stamina一hence its addition to energy-boosting sports drinks.
    People who consume a lot of caffeine regularly may develop temporary withdrawal symptoms,headache
    being the most common,if they quit or cut back on it abruptly. Fortunately,these symptoms last only a day
    or two in most cases.Individuals who are more sensitive to the stimulatory side effects of caffeine may want to
    avoid it,but most doctors agree that the equivalent of three cups of coffee a day does not harm healthy
    people.There is no medical basis to give up daily caffeine and many reasons to include a moderate amount in
    one's diet.

    Some athletes use caffeine to_________.
    A:improve their speed
    B:increase their endurance
    C:maintain their alertness
    D:relax their muscles

    答案:B
    解析:
    由文章第一段第三句中“Habitual coffee and tea drinkers had long been observed to have a lower incidence of non-melanoma skin cancers”可知,有喝咖啡和茶叶习惯的人患黑色素瘤皮肤 癌的可能性较低,故选B。
    由文章第二段最后一句中“it can alleviate headaches”可知,咖啡因可以用来治头痛。
    由文章第三段最后一句可知,咖啡因能增强跑步运动员和自行车运动员的耐力,即en- durance,故选B。
    由文章最后一段前两句话可知,退瘾症状仅持续一到两天,即short-lived,故选D。
    由文章最后一段的倒数第二句中“most doctors agree that the equivalent of three cups of coffee。day does not harm healthy people”可知,多数医生都认为一天喝三杯咖啡对健康的人不会产生不良影响,因此可能不会产生什么问题,故选C。

    Why Buy Shade-Grown Coffee?
    When people argue about whether coffee is good for health,they're usually thinking of the health of the coffee drinker. Is it good for your heart?Does it increase blood pressure?Does it help you concentrate?However,coffee affects the health of the human population in other ways, too.
    Traditionally, coffee bushes were planted under the canopy(树冠)of taller indigenous(土生土长的)trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees.At first,this increases production because more coffee bushes can be plan-ted if there aren't any trees.With increased production come increased profits.
    Unfortunately,deforesting for coffee production immediately decreases local wildlife habitat. Native birds nest and hide from predators(捕食者)in the tall trees and migrating birds rest there.
    Furthermore,in the long term,the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee.The fertilizers and pesti- cides kill insects that eat coffee plant,but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.
    Fortunately,farmers in Central and South America are beginning to grow more coffee bushes in the shade .We can support these farmers by buying coffee with such labels as"shade grown" and"bird friendly."Sure,these varieties might cost a little more.But we're paying for the health of the birds,the land,ourselves,and the planet. I think it's worth it.

    The function of the word"Traditionally"in Paragraph 2 is to show______.
    A: the positive effects of coffee
    B: a change of coffee growth
    C: something that is the most important
    D: how coffee production used to be

    答案:B
    解析:
    主旨大意题。文章首段提出咖啡对人类健康的影响,紧接着三段讲述全日照咖啡对生态环境的破坏,最后一段讲述美国中部和南部的农民在树荫下种植咖啡,引出文章主旨,并鼓励人们买这种咖啡。因此本题选D。
    文章由传统(traditionally)种植咖啡的方法(full-sun method)发展到现在种植咖啡的方法(shade-grown),显而易见,traditionally是用来展示咖啡种植的变化。
    由文章第二段中的“At first, this increases production... With increased production come increased profits.”可知,全日照咖啡的增产带来了更高的利润。故本题选D。
    根据第二段中的“However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees.”可知,农民们通过砍伐森林来获得更多的土地。
    文章第四段提到了全日照咖啡种植的影响,包括对昆虫,鸟,其他动物,水,甚至人类的影响,但并没有提到对空气的影响。因此选择B。

    Caffeine does not alter the need for sleep,but it does offer a temporary solution to fatigue for people who
    need to stay alert. Research has shown that sleep-deprived individuals who consumed caffeine had improved
    memory and reasoning abilities,at least in the short term. Studies of runners and cyclists have shown that
    caffeine can improve their stamina一hence its addition to energy-boosting sports drinks.
    People who consume a lot of caffeine regularly may develop temporary withdrawal symptoms,headache
    being the most common,if they quit or cut back on it abruptly. Fortunately,these symptoms last only a day
    or two in most cases.Individuals who are more sensitive to the stimulatory side effects of caffeine may want to
    avoid it,but most doctors agree that the equivalent of three cups of coffee a day does not harm healthy
    people.There is no medical basis to give up daily caffeine and many reasons to include a moderate amount in
    one's diet.

    Caffeine is used to_________.
    A:reduce high blood pressure
    B:relieve headaches
    C:cure liver cancer
    D:treat skin cancer

    答案:B
    解析:

    由文章第二段最后一句中“it can alleviate headaches”可知,咖啡因可以用来治头痛。
    由文章第三段最后一句可知,咖啡因能增强跑步运动员和自行车运动员的耐力,即en- durance,故选B。
    由文章最后一段前两句话可知,退瘾症状仅持续一到两天,即short-lived,故选D。
    由文章最后一段的倒数第二句中“most doctors agree that the equivalent of three cups of coffee。day does not harm healthy people”可知,多数医生都认为一天喝三杯咖啡对健康的人不会产生不良影响,因此可能不会产生什么问题,故选C。

    Why Buy Shade-Grown Coffee?
    When people argue about whether coffee is good for health,they're usually thinking of the health of the coffee drinker. Is it good for your heart?Does it increase blood pressure?Does it help you concentrate?However,coffee affects the health of the human population in other ways, too.
    Traditionally, coffee bushes were planted under the canopy(树冠)of taller indigenous(土生土长的)trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees.At first,this increases production because more coffee bushes can be plan-ted if there aren't any trees.With increased production come increased profits.
    Unfortunately,deforesting for coffee production immediately decreases local wildlife habitat. Native birds nest and hide from predators(捕食者)in the tall trees and migrating birds rest there.
    Furthermore,in the long term,the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee.The fertilizers and pesti- cides kill insects that eat coffee plant,but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.
    Fortunately,farmers in Central and South America are beginning to grow more coffee bushes in the shade .We can support these farmers by buying coffee with such labels as"shade grown" and"bird friendly."Sure,these varieties might cost a little more.But we're paying for the health of the birds,the land,ourselves,and the planet. I think it's worth it.

    What is the main idea of this passage?
    A: Farmers are changing the way they grow coffee.
    B: Coffee is becoming more expensive to produce.
    C: Shade-grown coffee is more expensive than sun-grown coffee.
    D: People should buy shade-grown coffee.

    答案:D
    解析:
    主旨大意题。文章首段提出咖啡对人类健康的影响,紧接着三段讲述全日照咖啡对生态环境的破坏,最后一段讲述美国中部和南部的农民在树荫下种植咖啡,引出文章主旨,并鼓励人们买这种咖啡。因此本题选D。
    文章由传统(traditionally)种植咖啡的方法(full-sun method)发展到现在种植咖啡的方法(shade-grown),显而易见,traditionally是用来展示咖啡种植的变化。
    由文章第二段中的“At first, this increases production... With increased production come increased profits.”可知,全日照咖啡的增产带来了更高的利润。故本题选D。
    根据第二段中的“However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees.”可知,农民们通过砍伐森林来获得更多的土地。
    文章第四段提到了全日照咖啡种植的影响,包括对昆虫,鸟,其他动物,水,甚至人类的影响,但并没有提到对空气的影响。因此选择B。

    正确答案:
    【参考译文】
    当人们讨论咖啡是否有益于健康时,通常情况下,他们考虑的是喝咖啡的人的健康。咖啡对你的心脏有好处吗?会增高血压吗?会帮助你提高注意力吗?其实,咖啡还通过其他途径影响着人类的健康。
    按传统,咖啡灌木丛都种植在土生土长的大树树冠之下。但是,在拉丁美洲越来越多的农民通过砍伐森林将咖啡种植在阳光充足的旷野上。刚开始,因为没有了那么多的树木,种植的咖啡灌木增多了,咖啡的产量因此增长了。产量增长了,利润就增加了。
    可惜的是,为增加咖啡产量而砍伐森林,这很快就使当地的野生动物栖息地变少。当地的鸟类需要在大树上筑巢,而且为了躲避捕食者也需要藏在大树里。还有迁徙而来的鸟儿也要在那些大树上休息。
    而且,从长远来看,这种充足阳光的种植方法会破坏生态系统,因为如果用这种方法种植咖啡,就需要用更多的化学肥料和杀虫剂。化肥和杀虫剂可以杀掉那些伤害咖啡作物的昆虫,但是随后鸟儿吃下中毒的昆虫之后也会死掉。化学药品还会杀死其它动物,或者让它们患病,甚至最终会进入到人们的饮用水之中。
    庆幸的是,美国中部和南部的农民开始更多地在避光处种植咖啡。如果我们购买标签上写有如“避光生长”或“鸟类无害”的咖啡,那么我们就可以通过这种方法支持那些农民。当然,这些种类的咖啡价格较高。但是,我们是为了鸟儿、大地、我们自己以及地球的健康买单。我认为这是值得的。
