Carbon Footprint
How often do you travel by plane?How much electricity do you use?
These days everyone is worried about the size of their carbon footprint.In order to reduce global warming we need to make our carbon footprints smaller. But how much CO2 are we responsible for?
A new book might be able to help.The Carbon Footprint of Everything looks at the different things we do and buy,and calculates the amount of CO2 all of the following created:the ingredients, the electricity used in the brewery，the equipment,the travel and commuting of the beer,and the packaging. It's amazing how many different things need to be included in each calculation.And it's frightening how much carbon dioxide everything produces.
But all of this can help us decide which beer to drink.From Berners-Lee's calculations,it's clear that a pint(568ml)of locally-brewed beer has a smaller carbon footprint than a bottle of imported beer. This is because the imported beer has been transported from far away,and it uses more packaging. The local beer only produces 300g of CO2,but the imported beer produces 900g! So, one pint of local beer is better for the environment than three cans of cheap foreign lager from the supermarket.
Berners-Lee has even calculated the carbon footprint of cycling to work.Nothing is more environmentally-friendly than riding a bike,surely?Well,it depends on what you've had to eat before. To ride a bike we need energy and for energy we need food.So if we eat a banana and then ride a kilometer and a half,our footprint is 65g of CO2.However,if we eat bacon before the bike ride,it's 200g. In fact,bananas are good in general because they don't need packaging,they can be transported by boat and they grow in natural sunlight.
So,does this mean that cycling is bad for the environment?Absolutely not,for a start,if you cycle,you don't use your car,and the fewer cars on the road,the fewer traffic jams.And cars in traffic jams produce three times more CO2 than cars traveling at speed.Cycling also makes you healthy and less likely to go to a hospital. And hospitals have very big carbon footprints!
So maybe it's time for us all to start making some changes.Pass me a banana and a pint of local beer,please.

参考答案和解析
答案：C
解析：
细节题。根据原文可知以下产生的二氧化碳量分别是：A选项，一品脱当地酿造的啤酒为300克，B选项，一品脱进口啤酒为900克，C选项，骑车前吃的香蕉为65克， D选项，骑车前吃的培根肉是200克。
词义推断题。第三段第二句：原料、xxx所用的电量、设备、啤酒的运输和包装。由此可知A最合理，B’选项与原文的“设备”重复了，D选项同理，C选项与包装重复了。
推断题。从第六段可以看出骑车是环保的，产生的碳足迹是少的，其他选项都没有在原文中体现这个意思。
推断题。第五段最后一句：香蕉总体来说是很好的，因为它们无需包装，可以使用船只运输，并且在自然光照下生长。这些都是说香蕉产生的碳足迹少，并没有提到它是健康食品。A、B、D原文均有体现。
主旨题。本文大意是阐述了我们的碳足迹量有多少。A、B和C均只是原文中的一点。
