However, some of the “green truths” are ②completely (complete) false. Firstly, ③making (make) a paper bag uses much more energy than a plastic one. So, not only plastic bags, ④but also paper bags are bad for the environment. Secondly, a device ⑤which/that is turned off still uses power. Therefore, we should remove the plug from its power supply. Thirdly, although local food does not need to ⑥be_transported (transport) long distances, it is ⑦the production of food, not its transport, that uses most of the energy and produces most of the greenhouse gases. Finally, it depends ⑧on the time you spend in the shower whether it's better to take a shower than a bath. Therefore, you'd better ⑨shorten (short) your shower time. In a word, it is worth ⑩thinking (think) about the common ideas and opinions before we take action. 学科网（北京）股份有限公司 $
