选修6 Unit 4 Global warming全球变暖晨读·记忆Refresh Our EnvironmentAs the director stated on behalf of his researching group, the data of this graph makes a clear presentation of the future environmental tendency. On one hand, the quantity of fuel keeps on decreasing by 9% per year while the growth of a wide range of pollution has been a global trend. On the other hand, the mildly but steadily going up of the average temperature is resulting in catastrophes like widespread floods. Without disagreement, they subscribe to the view that it is humans’ existence and their randomly consuming energy that result in this phenomenon.Many people have a commitment that developing nuclear power or energy from outer space will stop bad consequences coming about. However, scientists and educators are opposed to this view even if our needs may be met on the whole. They tend toadvocate refreshing our circumstances by saving energy and recycling waste. It is suggested that we use energy-saving appliances such as electrical motors, microwaves and so on and not be casual about little things like recycling a can. So please glance around and see what you can do. So long as everybody makes contribution, we will not have to put up with this problem anymore.恢复环境生机正如那位主任代表他的研究小组所说明的那样，这张图表的数据清楚地描述了未来环境的趋势：一方面，燃料的数量以每年9%的速度持续减少，同时，大范围污染的增长已经成为一种全球趋势;另一反面，平均气温轻微却稳定地升高正在造成像广泛的洪涝那样的灾难。

核心素养测评二十九选修6 Unit 4 Global Warming(限时35分钟)Ⅰ. 阅读理解AThese 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 (a leading expert in carbon foot-printing) might be able to help. The Carbon Footprint of Everything looks at the different things we do and buy, and calculates the amount of CO2they produce, including the ingredients, the electricity, the equipment, the transport and the packaging. 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 (568 ml) of locally-brewed (酿制的) 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 beer 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 65 g of CO2. However, if we eat bacon before the bike ride, it’s 200 g. 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. If you cycle, you don’t use your car; and the fewer cars on the road, the fewer trafficjams. And cars in traffic jams produce three times more CO2 than cars travelling 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.【文章大意】这是一篇争论文。
