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 （等價物）．Consequently，skip the bottled water and drink tap water，both at home and at restaurants．Additionally，bottled water is not necessarily cleaner than tap．

點(diǎn)評 做閱讀時經(jīng)常犯錯的主要原因是，僅憑讀過文章后殘留在腦海中的一絲印象來勾選答案，這樣便很容易掉入出題人故意設(shè)布下的題目陷阱．所謂閱讀理解，對于題目的理解一定要忠實(shí)于原文，因此，每一道題都應(yīng)該與原文作全面的對比與核查，再得出答案．也就是說，閱讀理解的每一道題目，在原文都應(yīng)該有明確的出處，我們把這一出處叫做原文相關(guān)句，（1）排除與原文相關(guān)句主題不一致的選項(xiàng)（2）排除與原文相關(guān)句態(tài)度相反的選項(xiàng)  （3）排除用于過于極端或負(fù)面的選項(xiàng)（4）注意結(jié)合文章主旨和主題去排除．
