12．At present，too much carbon dioxide（二氧化碳） makes the earth warmer and causes terrible effect to human beings．To save our planet，to save ourselves，a new lifestyle called low-carbon life（低碳生活） becomes popular．Low carbon means low energy and no waste．It is necessary for everybody to learn to live a low-carbon life．
To live a low-carbon life，we'd better save energy as much as possible．Turn off the lights and TV whenever they are not needed．If possible，use cold water to wash clothes or dishes．Take a short shower and try to take a cold one when the weather gets warm．Don't do the cooking with electricity．
To live a low-carbon life，we should eat less meat．Everybody knows eating too much meat makes people fat and easy to have heart disease，but maybe you don't know keeping animals for food produces even more carbon dioxide than all the cars in the world，and being a vegetarian can help reduce（減少） one and a half ton（噸） of carbon dioxide a year．Maybe it is a little difficult，but it's really necessary．
To live a low-carbon life，we are supposed to do less shopping．When we go shopping，we may drive a car or take other transportations．On the one hand，these machines pollute the air and waste energy．On the other hand，most of us always buy some useless things because of some advertisements．It is not only a waste of money but also causes trouble to the earth，because as you know，making everything will produce carbon dioxide more or less．
There are many other ways to live a low-carbon life，such as recycling things，planting trees and reusing textbooks．If we can keep it a habit in our daily life，the earth will become a safer planet for us to live on．

分析 短文大意：本文講述太多的二氧化碳使地球變暖，為了保護(hù)環(huán)境，應(yīng)提倡低碳生活．文章主要介紹幾種低碳生活的方式，如節(jié)約能源、少吃肉食、少購物等．
解答 56-60：CAACB
56題答案：C細(xì)節(jié)理解題．根據(jù)文中第一句At present，too much carbon dioxide（二氧化碳） makes the earth warmer and warmer and causes terrible effect to human beings．可知是太多的二氧化碳使地球變暖，所以該選C．
57題答案：A細(xì)節(jié)理解題．根據(jù)文中倒數(shù)第二段第二句Turn off the lights and TV whenever they are not needed．以及本段最后一句Don't do the cooking with electricity．可知，我們可以通過少用電來節(jié)約能源．所以該選A．
58題答案：A細(xì)節(jié)理解題．根據(jù)第三段第一句To live a low-carbon life，we should eat less meat．以及上下文意，可知本段主要在說明少吃肉也是低碳生活的一種方式．所以該選A．
59題答案：C細(xì)節(jié)理解題．根據(jù)文中第四段可知It is not only a waste of money but also causes trouble to the earth，because as you know，making everything will produce carbon dioxide more or less，可知少購物將少產(chǎn)生二氧化碳．所以該選C．
60題答案：B 主旨題．本文主旨是為何要減少二氧化碳的排量，以及如何過低碳生活，再結(jié)合最后一句 If we can keep it a habit in our daily life，the earth will become a safer planet for us to live on，可知若提倡低碳生活，二氧化碳當(dāng)然就會減少．所以該選B．
點評 題目涉及多道細(xì)節(jié)理解題，做題時結(jié)合原文和題目有針對 性找出相關(guān)語句進(jìn)行仔細(xì)分析，結(jié)合選項選出正確答案．推理判斷也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確的答案．
