【正文】 kaging. 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 BernersLee’s calculations, it’s clear that a pint (568ml) of locallybrewed 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. BernersLee has even calculated the carbon footprint of cycling to work. Nothing is more environmentallyfriendly 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. 66. According to BernersLee, which of the following produces the most carbon dioxide？ A.

They can use their sense of vision and smell to tell the difference between people who pose a threat and those who do not. In Kenya, researchers found that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear animals and thus pose a threat to elephants。 bar. D.

In all the countryside there was no garden so lovely as his. All sorts of flowers grew there, blooming in their proper order as the months went by, one flower taking another flower’s place, so that there were always beautiful things to see, and pleasant odors to smell. Hans had many friends, the most devoted being the Miller. So devoted was the rich Miller to Hans that he’d never go by his garden without plucking a large bunch of flowers or a handful of sweet herbs, or filling his pockets with fruits. The Miller used to talk about noble ideas, and Hans 9 nodded and smiled, feeling proud of having such a friend. The neighbors thought it strange that the rich Miller never gave Hans anything in return, though he had hundreds of sacks of flour, many cows and sheep, but Hans never troubled his head about these, and nothing gave him greater pleasure than to listen to all the wonderful things about the unselfishness of true friendship. In spring, summer, and autumn Hans was very happy, but when winter came, and he had no fruit or flowers to sell, he suffered from cold and hunger. Though extremely lonely, the Miller never came to see him then. ―There’s no good in going to see Hans while the snow lasts.‖ The Miller said to his wife, ―When people are in trouble they shouldn’t be bothered. So I’ll wait till the spring es when he’s happy to give me flowers.‖ ―You’re certainly very thoughtful,‖ answered his wife, ―It’s quite a treat to hear you talk about friendship.‖ ―Couldn’t we ask Hans up here?‖ said their son. ―I’ll give him half my meal, and show him my white rabbits.‖ ―How silly you are!‖ cried the Miller. ―I really don’t know what’s the use of sending you to school. If Hans came up here, and saw our warm fire, our good supper, and our red wine, he might get envious, and envy is a most terrible thing, and would spoil anybody’s nature. I am his best friend, and I’ll always watch over him, and see that he’s not led into any temptation. Besides, if Hans came here, he might ask me for some flour. Flour is one thing, and friendship is another, and they
