(1)Most of us are aware that we must take care of ① the environment, and the majority② of us take steps to save ③ energy and reduce waste and pollution. But recently, some “green truths” have been shown to be only half ④ true，or even completely false. Here are some common ones. Which are really green? 2．Paper shopping bags are better than plastic ones. (2)Plastic bags cause litter and are a danger to wild animals, which mistake them for⑤food. 　It takes hundreds of years for plastic to break down　⑥[1]，but much less time for paper. Because of this, people think paper bags are the better environmental choice. [1]此处是“It takes some time for sb./sth.to do sth.”句型表示“做某事花费……多少时间”。 (3)　However, making a paper bag uses four times as much energy as making a plastic bag and up to ⑦three times the amount⑧ of water.　[2]The process also produces more greenhouse gases⑨. (4) In fact, both kinds of bags are bad for the environment. So，take a reusable⑩ bag with you when you go shopping. [2]v.­ing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。 3．When you turn off a device，it stops using power⑪. (5)When we turn off a device, such as television，it goes into stand­by mode⑫. Devices in this mode still use power，and older devices in stand­by mode can use even more. This happens because electricity continues to leak⑬from the device，even when it is turned“off”．To make sure⑭ your appliance⑮ is in fact off, remove⑯ the plug from its power supply⑰. 4.Eating local food is good for the environment. (6)It seems like common sense⑱：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 more energy and produces most greenhouse gases.　[3]In some cases⑲，local produce might have used⑳ more energy and produced more greenhouse gas than produce grown a long way away­even 　taking into accounteq \o(○,\s\up1(21))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]现在分词短语 taking into account its transport 作让步状语。 5. It's better to take a shower than a bath. (7)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. (8)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]此处是“It's worth doing sth.”句型，表示“做某事是值的。”不定式 to see what's really green作目的状语。 参考译文 1.什么是真正的环保？ (1)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？ 2．纸购物袋比塑料购物袋好。 (2)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。 (3)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。 (4)实际上，这两种袋子对环境都是有害的，所以去购物的时候最好携带可重复使用的袋子。 3．关闭设备以后，它就停止用电了？ (5)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，而且越陈旧的设备，在待机模式下耗电越多。发生这种情况的原因是，即使“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。 4.吃当地食物对环境有益。 (6)这似乎是常识：吃当地食物会对环境更好，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。 5．淋浴比泡澡好。 (7)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。 (8)环保意识现在是日常生活的一部分。但是，(我们)应该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。 Ⅰ.Reading for main idea Why does the writer write the passage? A．He wants to introduce some new ways to save energy. B．He wants to correct the false green truths and show really green ones. C．He wants to call on more people to protect the environment. D．He wants to explain the importance of energy saving. 答案：B Ⅱ.Reading for structure People's awareness We take steps to save energy，however，some “green truths”are only 1.　half　 true，or even 2.　false　. Really green truths ·Both paper shopping bags and plastic ones are 3.　bad　 for the environment. ·Devices in 4.　stand­by　 mode still use power. ·5.　Production　 of food, not transport，uses most of the energy. ·It is not always 6.　better　 to take a shower than a bath. Way to be “greener” Check common ideas to see whether they are really 7.　green　. Ⅲ.Reading for the details 1．In the following, which one is not the disadvantage of plastic bags? A．Causing litter. B．Being treated as food by wild animals. C．Taking much more time to break down. D．Using much more energy to produce. 2．Which one is true according to fifth paragraph? A．Leaving a device in stand­by mode is environment­friendly. B．Older devices use less energy than new ones. C．Removing the plug from power supply will stop using power. D．Using electric devices as little as possible is the best way to save energy. 3．Why do people prefer to eat local food? A．Because it can save the energy used to transport. B．Because it tastes better than the food transported long away. C．Because its production uses less energy. D．Because it produces less greenhouse gas. 4．According to the passage, when should you take a shower? A．Anytime you like. B．When you spend less than 8 minutes in a shower. C．When your bath is quite large. D．When you use about 50 litres of water. 答案：1－4　DCAB Ⅳ.Post reading We have taken steps to save energy and reduce waste 1.　pollution　(pollute)．However，some of the green truths are even 2.　completely　(complete)false. Firstly, truths are that 3.　making　(make) a paper bag uses much more energy than a plastic one. So, not only plastic bags,4.　but 　also paper bags are bad for environment. Secondly, a device 5.　that /which　 is turned off still uses power. We should remove the plug from its power supply. Thirdly, local food needn't 6.　be transported　(transport)long distances, and 7.　what 　uses energy is the production of the food. Finally, it depends 8.　on　 the time you spend in the shower and the size of your bath to take a shower or bath. Therefore, you'd better 9.　shorten　(short)shower time. In a word, it is worth 10.　thinking 　(think) about the common ideas before we take actions.
