浙江省杭州学军20xx届高三第一次月考(编辑修改稿)内容摘要:

e 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. A pint of local beer we drink. B. A pint of imported beer we drink. 第 4 页 C. A banana we eat before a bike ride. D. The bacon we eat before a bike ride. 67. Why are bananas good in general? A.

To make our carbon footprints smaller, we should often ___________. A. cycle to work B. drink more local beer C. calculate the amount of CO2 D. buy cheap things from the supermarkets 70. What’s the most suitable title for the passage? A. Bikes, Beer and Bananas B. Starting to Make Changes C. How Big Is Your Carbon Footprint? D. The Carbon Footprint of Everything B It is easy for us to tell our friends from our enemies. But can other animals do the same? Elephants can! 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。 Kamba men are mainly farmers and are not a danger to elephants. In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants detected the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by Kamba men or clothing that had not been worn at all. Garment color also plays a role, though in a different way. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted aggressively toward the red clothing. The researchers believe that the elephants’ emotional reactions are due to their different interpretations of the smells and the sights. Smelling a potential danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and bee aggressive. 71. According to the passage, which of the following statements。
