Recently,environmentalists have encouraged us to buy local food.This reduces "food miles",
that is,the distance food travels to get from the producer to the seller.They reason that the
higher the food miles,the more carbon emissions ()Buying local food,therefore,has a
lower carbon footprint and is more environmentally friendly.
However,the real story is not as simple as that.If our aim is to reduce carbon emissions,we
must look at the whole farming process,not just transportation.According to a 2008 study,only
11%of carbon emissions in the food production process result from transportation,and only 4%
came from the final delivery (of the product from the producer to the seller.
In fact,imported food from other countries often has a lower carbon footprint than locally
grown food.Take apples,for example.In autumn,when apples are harvested,the best thing for
British people to do is to buy British apples.However,the apples we buy in winter or spring have
been kept refrigerated for months,and this uses up a lot of energy.In spring,therefore,it is more
energy-saving to import them from New Zealand,where they are in season.Heating also uses a lot
of energy,which is why growing tomatoes in heated greenhouses in the UK is less environmentally
friendly than importing them from Spain,where the tomatoes grow well in the local climate.
We must also take into consideration the type of transport.Transporting food by air creates
about 50 times more emissions than shipping it.However,only a small number of goods are flown
to foreign countries,and these are usually high value,perishable goods which we cannot
produce locally,such as seafood and out-of-season berries.Even then,these foods may not have

a higher carbon footprint than locally grown food.For example,beans flown in from Kenya are
grown in sunny fields using human labour and natural fertilisers(),unlike in Britain,where
we use oil-based fertilisers and machinery.Therefore,the total carbon footprint is still lower.
It's also worth remembering that a product's journey does not end at the supermarket.The
distance customers travel to buy their food,and the kind of transport they use will also add to its
carbon footprint.So driving a long way to shop for food will wipe out any environmental benefits
of buying locally grown produce.
Recently,some supermarkets have been trying to raise awareness of food miles by labelling
i)foods with stickers that show it has been imported by air.But the message this gives is too
simple.Lots of different factors contribute to a food's carbon footprint besides the distance it has
travelled.

答案与逐题解析
正确答案:32-34DBD
32.D (It shows how far the food goes from farmland to supermarkets.)
考点:细节理解题
语境分析:第一段明确提到"food miles,that is,the distance food travels to get from the producer
to the seller'”,producer对应farmland,seller对应supermarkets。
选项辨析:
·A”影响人们如何配送和运输食物”文中未提及
。B”如果鼓励购买本地食物会增加”与原文矛盾
。C”是导致食物碳排放的关键因素”与第二段数据不符
·D”显示食物从农田到超市的距离”符合定义
33.B(storing local food creates more carbon emissions than importing food)
考点:推理判断题
语境分析:第三段提到"winter or spring.apples..kept refrigerated for months,and this uses
up a lot of energy.In spring..import them from New Zealand..more energy--saving"”,说明储
存本地食物比进口当季食物碳排放更高。
选项辨析:
。A”空运食物最节能”与第四段数据矛盾
·B”储存本地食物比进口食物产生更多碳排放”符合文意
·C”人力和天然肥料会增加碳足迹”与第四段例子相反
·D”种植反季食物比进口当季食物耗能更少”与第三段矛盾
34.D (Doubtful)
考点:观点态度题
语境分析:文章通过多段论证说明”减少食物里程以降低碳排放”的观点过于简单,最后一段明
确指出'the message..is too simple”。
选项辨析:
。A”支持的”与全文基调不符
。B”困惑的”不准确,作者思路清晰
·C”否定的”过于绝对
