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 by Mike Berners Lee, an expert, might be able to help. The carbon footprint looks at the different things we do and buy, and calculates the amount of CO₂ all of the following created: the ingredients, the electricity, 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.
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.
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, our footprint is 65g of CO₂. However, if we eat bacon before the ride, it’s 200g. In fact, bananas are good 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 hospital. So maybe it’s time for us all to start making some changes. Pass me a banana and a pint of local beer, please.

答案

小题1:C
小题2:A
小题3:B
小题4:C

解析

文章是号召大家采取行动减少温室气体的排放，以及一些具体的做法。
小题1:细节题。根据文章倒数第二段最后两行In fact, bananas are good because they don’t need packaging, they can be transported by boat and they grow in natural sunlight.
小题2:猜测词义题。根据后半句话中的than a bottle of imported beer.可知前面是指当地生产的啤酒。
小题3:目的意图题。通读全文可知文章是号召大家采取行动减少温室气体的排放的。
小题4:文章是关于环境保护方面，那么应该是来自科学报告。
