题目

根据短文内容，从短文后选项中选出能填入空白处的最佳选项。选项有两项为多余选项。 What's really green? Most of us are aware that we must take care of the environment, and the majority of us take steps to save energy and reduce waste and pollution. But recently, some "green truths" have been shown to be only half true, or even completely false. Paper shopping bags are better than plastic ones. Plastic bags cause litter and are a danger to wild animals, which mistake them for food. It takes hundreds of years for plastic to break down, but much less time for paper. Because of this, people think paper bags are the better environmental choice. However, making a paper bag uses four times as much energy as making a plastic bag and up to three times the amount of water. In fact, both kinds of bags are bad for the environment. So, take a reusable bag with you when you go shopping. It seems like common sense: eating local food should be better for the environment, because it does not need to be transported long distances and kept cold during transport. It is the production of food, not its transport, that uses most of the energy and produces most of the greenhouse gases. In some cases, local produce might have used more energy and produced more greenhouse gases than produce grown a long way away-even taking into account its transport. It's better to take a shower than a bath. 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. A. So say no to plastic bags. B. Here are some common ones. C. Unfortunately, it is not that simple. D. Eating local food is good for the environment. E. The process also produces more greenhouse gases. F. It's time that we took measures to protect our environment. G. It depends on how long you spend in the shower and how large your bath is. 答案：【1】B【2】E【3】D【4】C【5】G
