【版本：外研　册别：必修二】 Developing ideas — reading Unit 6 Earth First Look at the questions about “green living” and tick your answers. Which shopping bag is more environmentally friendly? A plastic bag. A paper bag. Neither of these. Look at the questions about “green living” and tick your answers. 2. What should you do to save energy when leaving your home? Turn off a device. Unplug a device. Neither of these. Look at the questions about “green living” and tick your answers. 3. What food is better for the environment? Food produced near to where you live. Food produced far from where you live. It depends. Look at the questions about “green living” and tick your answers. 4. Which uses less water? Taking a bath. Taking a shower. It depends. What’s really green? Read the passage (P90-92) and find the answer. As subheadings expand on the main heading or title, they can be slightly longer than the main heading. Although not every paragraph needs a subheading, they can be skimmed to give the reader an overall understanding of the content of a text. Learning to learn Read the four subheadings in the passage and decide if they are true or false. ? Paper shopping bags are better than plastic ones. ? When you turn off a device, it stops using power. ? Eating local food is good for the environment. ? It’s better to take a shower than a bath. Then read the passage and check your answers. 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. The process also produces more greenhouse gases. In fact, both kinds of bags are bad for the environment. So, take a reusable bag with you when you go shopping. Paper shopping bags are better than plastic ones. 8 When you turn off a device, it stops using power. When we turn off a device, such as television, it goes into stand-by mode. Devices in this mode still use power, and older devices in stand-by mode can use even more. To make sure your appliance is in fact off, remove the plug from its power supply. 9 Apart from the transport, we should take the production of food into account. Eating local food is good for the environment. 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. 10 The key is to keep your shower time as short as possible. 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. 11 Figure out the structure of the passage. Introduction Conclusion 12 Body green truth 1 green truth 2 green truth 3 green truth 4 Give a talk about one of the “green truths” in the passage. writing assignment • Which “green truth” are you going to talk about? • Why do people believe it is “green”? • Why is it not completely true? • What can you do to become “greener”? Use these questions to help plan your talk. writing assignment Today I would like to talk about if paper shopping bags are better than plastic bags. As everyone knows, plastic bags cause litter and are a danger to wild animals. It takes hundreds of years for plastic bags to break down. Therefore, plastic bags are bad for the environment. Because of this, some people think paper bags are better than plastic ones. But that is not true. 14 writing assignment Making paper bags uses much more energy and water. It also produces more green house gases. So we come to the conclusion that paper bags are not environmentally friendly, either. Since both of the above are not good for the environment, what's really green? I suggest taking a reusable bag with you when shopping. It is really green. Starting from the small things around us, everyone can become a real "greener". Thanks null, track 7 204446.42 $
