It’s popular today for people and company to try to offset their carbon footprint. But there is a lot of debate about how to measure that footprint. Now a new program called Carbon hero may have one solution. The device was invented by a graduate student of royal college of art in London. and recently 2007 European Satellite Navigation competition. The idea is to get a accurate read on how much carbon you use as you travel. It’s a hand-held of unit, about the size of a key chain, it automatically identifies the form of transportation the carrier is taking by measuring the speed, location and pattern of the movement. Then the information is automatically downloaded to a cell phone, which immediately displays the carbon generated and the impact of the user’s actions.
Of course the device doesn’t measure other aspects of carbon footprint such as the size of your house. And it’s not available to consumers. But inventor hopes to develop the device, and that immediate feedback will convince people to change their transportation. Maybe to walking, which leaves a tiny footprint.

原稿 2. Recipe For Snow Includes Cloud Microbes Next time you’re shoveling snow off your walk, don’t blame the weatherman—blame bacteria. Because an international team of scientists has found that microbes that float through the atmosphere can seed the formation of ice crystals in clouds. Crystals that then precipitate snow. The discovery is described in the February 29 issue of Science.
Some bacteria, including bugs that infect plants, have been known to catalyze the growth of ice here on earth. So the scientists got to wondering whether they might do the same in the sky. Making atmospheric ice crystals is the first step in any recipe for precipitation, whether the final dish is rain or sleet or snow. So the scientists collected fresh snow from various places around the world, including the French Alps, Antarctica and Bozeman, Montana . They found that most of their samples contained cells and cell fragments, and that these biological materials were capable of nucleating the growth of ice.
How the bugs got there in the first place is anybody’s guess. The scientists figure microbes may drift thousands of miles before they get caught up in a cloud and scare up a storm. Just something to ponder next time you stick out your tongue to catch a pretty snowflake.

一起来听写吧。其实，这个是XDF老师原来给的听力资料。
继续加油！~
