Question

3．Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment．Here are some guidelines to follow：
Choose foods thoughtfully
Americans have never had such a variety or abundance of food to choose from．Besides so many choices，we now hear about our"food print"，the amount of land needed to supply one person's nutritional needs for a year．Do we buy cherry tomatoes from Mexico or tomatoes grown locally in a hothouse？Do we get the Granny Smiths from the farmers'market or the supermarket？Is organic produce healthier for us and the planet？
These are very complex issues that require analysis of many criteria，including the energy used in producing and transporting the food，as well as the type of soil and methods of raising the food．
Despite the complexities，there are some general guidelines you can follow．For instance，eat less meat or eat low on the food chain．Your doctor may have recommended you to restrict your consumption of red meat because of its too much fat content．Beyond that，there are environmental reasons，too．Raising food animals contributes substantially to climate change because a meat-based diet requires more land，energy and water than a plant-based one．
______________________________
Drinking plenty of fluids is significant during hot weather or when exercising．But is bottled water the way to go？You may not think so when seeing the true costs．Based on a survey，manufacturing the 30-plus billion plastic water bottles can produce more than 2.5 million tons of carbon dioxide and use three times the amount of water in the bottle．Adding in transportation，the energy used comes to over 50 million barrels of oil equivalent （等价物）．Consequently，skip the bottled water and drink tap water，both at home and at restaurants．Additionally，bottled water is not necessarily cleaner than tap．

点评 做阅读时经常犯错的主要原因是，仅凭读过文章后残留在脑海中的一丝印象来勾选答案，这样便很容易掉入出题人故意设布下的题目陷阱．所谓阅读理解，对于题目的理解一定要忠实于原文，因此，每一道题都应该与原文作全面的对比与核查，再得出答案．也就是说，阅读理解的每一道题目，在原文都应该有明确的出处，我们把这一出处叫做原文相关句，（1）排除与原文相关句主题不一致的选项（2）排除与原文相关句态度相反的选项  （3）排除用于过于极端或负面的选项（4）注意结合文章主旨和主题去排除．
