Ⅲ.品质升华 1．Which of the “green truths” in the passage amazes you most? Why? (Critical Thinking批判性思维) “Devices in stand-by mode still use power” amazes me most, because I have never removed the plug from its power before.And I don't think electricity keeps leaking even when we “turn off” the device before reading the article. 2．What things can you do to be “greener” in daily life? (Divergent Thinking发散性思维) Taking public transportation, turning off the tap after using the water, avoiding disposable cups, chopsticks and so on. 学生用书第161页 ◎ ①take care of照顾，照料，爱护 [近义]look after，care for ②majority/mə'dʒɒrəti/n.多数，大多数(人或物) ③take steps to do sth 采取措施做某事 ④reduce waste and pollution减少浪费与污染 ⑤be half true不完全正确 half熟词生义 adv.部分地 ⑥mistake...for...把……错当成…… ⑦break down分解；(机械等)出故障；(人)身体出毛病，垮掉 ⑧up to达到(某数量、程度等)，至多有 ⑨amount/ə'maʊnt/n.数量，数额 ⑩greenhouse gases温室气体 ⑪a reusable bag可重复使用的袋子 reusable /riː'juːzəb(ə)l/ adj.可再度使用的，可多次使用的 ⑫stop doing sth 停止做某事 [辨析]stop to do sth 停下(正在做的事)去做另一件事 ⑬go into stand-by mode进入待机模式 stand-by/'stændbaɪ/adj.备用的 mode/məʊd/n.(机器、设备的)运行方式，状态，模式 ⑭leak/liːk/v.(使)漏，(使)渗漏 ⑮make sure确保，设法保证 ⑯appliance/ə'plaɪəns/n.家用电器，家用器具 ⑰remove/rɪ'muːv/v.移走，搬走，去掉 remove...from...把……从……移走/去掉 ⑱the power supply电源 ⑲common sense 常识 ⑳in some cases在某些情况下 ㉑might have done sth 过去可能做过某事 ㉒take...into account 把……考虑进去 ◎ What's really green? Most of us are aware that we must take care of① the environment，and the majority② of us take steps to③ save energy and reduce waste and pollution④.But recently，some “green truths” have been shown to be only half true⑤，or even completely false.Here are some common ones.Which are really green? ？Paper shopping bags are better than plastic ones. Plastic bags cause litter and are a danger to wild animals，which mistake them for⑥ food.It takes hundreds of years for plastic to break down⑦[1]，but much less time for paper.Because of this，people think paper bags are the better environmental choice. [1]画线部分为“It takes some time for sb /sth to do sth”句型，表示“做某事花费某人/某物多少时间”。 However，making a paper bag uses four times as much energy as making a plastic bag and up to⑧ three times the amount⑨ of water.[2]The process also produces more greenhouse gases⑩. [2]动词-ing形式短语making a paper bag作主语，谓语动词应用单数形式；four times as much energy as...是“倍数＋as...as...”结构的倍数表达法，three times the amount of water 是“倍数＋the amount/size/height/weight/length/...＋of...”结构的倍数表达法。 In fact，both kinds of bags are bad for the environment.So，take a reusable bag⑪ with you when you go shopping. ？When you turn off a device，it stops using⑫ power. When we turn off a device，such as television，it goes into stand-by mode⑬.Devices in this mode still use power，and older devices in stand-by mode can use even more.This happens because electricity continues to leak⑭ from the device，even when it is turned “off”．To make sure⑮ your appliance⑯ is in fact off，remove⑰ the plug from its power supply⑱. 学生用书第162页 ？Eating local food is good for the environment. It seems like common sense⑲：eating local food should be better for the environment，because it does not need to be transported long distances and kept cold during transport.Unfortunately，it is not that simple.It is the production of food，not its transport，that uses most of the energy and produces most of the greenhouse gases.[3]In some cases⑳，local produce might have used㉑ more energy and produced more greenhouse gases than produce grown a long way away— even taking into account㉒ its transport[4]. [3]本句是强调句型，即“It is/was＋被强调部分＋that/who...”。本句强调的是主语the production of food。 [4]动词-ing形式短语taking into account its transport作让步状语。 ？It's better to take a shower than a bath. It depends on how long you spend in the shower and how large your bath is.If you spend more than eight minutes in a shower，you'll use as much water as in a bath—about 50 litres of water.Therefore，the key is to keep your shower time as short as possible. Environmental awareness is now part of daily life.But it's worth checking common ideas and opinions to see what's really green.[5] [5]画线部分为“It's worth doing sth”句型，表示“做某事是值得的”。动词不定式to see what's really green 作目的状语。 ◎ 什么是真正的环保？ 我们大多数人都知道，我们必须爱护环境，大部分人也会采取措施来节约能源，减少浪费与污染。不过，最近有一些“环保真理”被证明并不完全正确，甚至是完全错误的。这里有一些常见的“环保真理”，哪些才是真正环保的呢？ ？纸质购物袋比塑料购物袋好。 塑料袋会造成垃圾，给误将其当作食物的野生动物带来危险。塑料需要几百年的时间才能分解，但纸张分解所需的时间则少得多。因此，人们认为纸袋是更好的环保选择。 但是，制造一个纸袋消耗的能量是制造一个塑料袋的四倍，用水量多达三倍，生产过程也会产生更多的温室气体。 实际上，这两种袋子对环境都是有害的。因此，你去购物的时候最好携带可重复使用的袋子。 学生用书第163页 ？关闭设备以后，它就停止用电了。 我们关闭设备时，比如电视，它就会进入待机模式。这种模式下的设备仍然在用电，而且陈旧一些的设备，在待机模式下耗电甚至会更多。发生这种情况的原因是，即使被“关闭”以后，设备还在继续漏电。要确保电器彻底关闭，就得从电源上拔下插头。 ？吃当地食物对环境有益。 这似乎是常识：吃当地食物应该对环境更好，因为当地食物不需要长途运输，也不需要在运输期间冷藏。可惜，事实没那么简单。大部分的能源消耗和温室气体产生源于食物的生产，而非运输过程。在某些情况下，当地农产品可能比遥远地方种植的农产品消耗更多的能源，产生更多的温室气体，哪怕把运输因素考虑进去(也是如此)。 ？淋浴比泡澡好。 这取决于你的淋浴时间，以及你的浴缸有多大。如果你一次淋浴超过8分钟，所用的水将和泡澡的水一样多——大约50升。因此，关键在于尽可能缩短淋浴时间。 现在环保意识是日常生活的一部分。但是，核实一下人们公认的想法和意见，看看什么才是真正的环保之道是值得的。 ◎核心单词——练通 1．false data 错误的数据 2．a small amount of water 少量的水 3．turn off a
