3、 to produce. 3. Why do people prefer to each local food? A. Because it can save the energy used to transport. B. Because it tastes better than the food transported long away. C.

Secondly, a device _ is turned off still uses power. We should remove the plug from its power supply. Thirdly, local food neednt _ (transp

7、ctions. Task 3: Gap filling Whats really green? Most of us are aware (意识到) that we must take care of the environment, and the majority of us take steps to save energy and reduce waste and pollution(我们大多数人采取措施节省能源, 减少浪费和 污染). But recently, some “green truth” have been shown (show) to be only half tru

8、e, or even completely false. Here are some common (常见的) ones. Which are really green? Paper shopping bags are better than plastic ones. Plastic bags cause litter (导致垃圾) and are a danger to wild animals, which mistake them for food (把它们错当成食物). It takes hundreds of years for plastic to break down (分解)

9、, but much less time for paper. Because of this, people think paper bags are the better environmental (environment) choice. However, making a paper bag uses four times as much energy as making (make) a plastic bag and up to three times the amount (数量) of water. The process (过程) also produces more gr

10、eenhouse gases (温 室气体). In fact, both kinds of bags are bad for the environment. So, take a reusable (重复利用的) bag with you when you go shopping. When you turn off a device (设备), it stops using power. When we turn off (关掉) a device, such as television, it goes into stand-by mode (待机模式). Devices in thi

11、s mode still use power (耗电;用电), and older devices in stand-by mode can use even more (much). This happens because electricity (电) continues to leak (流失) from the device, even when it is turned “off”. To make sure your appliance (家用电器) is in fact off, remove the plug from its power supply (从 电源上拔下电器插

12、头). Eating local food is good for the environment It seems like common sense (常识): eating local food should be better for the environment, because it does not need to be transported (transport) long distances and kept cold during transport. Unfortunately (fortunate), it is not that simple. It is the

13、 production of food, not its transport, that uses most of the energy and produces most of the greenhouse gases. In some cases (在有些情况下), local produce (本地的农产 品) might have used more energy and produced more greenhouse gases than produce grown a long way away even taking into account its transport (将运

14、输的因素考虑在内). Its better to take a shower (淋浴) than a bath. It depends on (取决于) how long you spend in the shower and how large your bath is. If you spend more than eight minutes in a shower, youll use as much water as in bath about 50 liters of water. Therefore, the key is to keep your shower time as s

15、hort as possible (尽可能短). Environmental awareness (环保意识) is now part of daily life. But its worth checking (check) common ideas and opinions (习以为常的理念和观念) to see whats really green. 【教师版】【教师版】 Task 1: Reading comprehension 1. Why does the writer write the passage? ( B ) A.

Firstly, making (make) a paper bag uses much more energy than a plastic one. So, not only plastic bags, but also paper bags are bad

20、 for environment. Secondly, a device which/that is turned off still uses power. We should remove the plug from its power supply. Thirdly, local food neednt transported (transport) long distances, and what uses energy is the production of the food. Finally, it depends on/upon the time you spend in th

21、e shower and the size of your bath to take a shower or bath. Therefore, youd better shorten (short) your shower time. In a word, it is worth thinking (think) about the common ideas before we take actions. Task 3: Gap filling 答案请参考课本答案请参考课本 _ 课文翻译请参考下文:课文翻译请参考下文: 哪些才是真正的环保做法哪些才是真正的环保做法? ? 我们大都分人都意识到要

22、保护环境,也采取了各种行动节约能源,减少浪费和污染。但是近来, 一些“绿色环保真相”被证实并非完全正确,甚至是无稽之谈。下面列举了一些常见的环保观念, 其中那些是正确的呢? 纸质物袋优于塑料袋?纸质物袋优于塑料袋? 塑料袋会变成垃圾,被野生动物误食后会对其造成伤言。 塑料需要数百年才能分解,而纸的降解 时间要短得多,因此人们认为纸袋是更为环保的选择。 然而,生产纸袋的耗能为塑料袋的四倍,耗水则多达三倍。 其生产过程也会产生更多的温室气体。 事实上这两种袋子都不够环保,所以出门购物时请带一个能重复利用的袋子 关掉的电器不耗电关掉的电器不耗电? ? 当我们关掉电视等电器时,它会进入待机状态。 这种

23、状态下的电器仍然耗电,而且越旧的电器毛 电越多。这是因为电器即使已经被“关掉”了,却依然有电流从电器中流失。为确保电器设备彻底 关闭,请从电源上拔下电器插头。 吃本地食物更利于环保吃本地食物更利于环保? ? 这似乎已是人们常识性的认识:吃本地产的食物更环保,因为不需要长途低温运输。 然而事实井 没有那么简单。相比于运输,食物的生产过程才是消耗大部分能源及产生大部分温室气体的原因。 在有些情况下,即使将运输的因素考虑在内,本地的农产品也可能比距离遥运的外地种植的农产品 耗能更多,产生的温室气体也更多。 淋溶比泡澡更好淋溶比泡澡更好? ? 这取决于你淋浴的时间和你的浴缸大小。如果淋浴超过八分钟,那么耗水量就和泡澡一样多 大约为五十升水。所以,节水的关键在于尽量缩短淋溶的时间。 环保意识已经融人了人们的日常生活,但我们仍需仔辨别我们已经习以为常的理念和观点中哪 些才是真正“绿色环保”的。
