共享题干题 (一)根据材料，回答下列的问题： Looking to help the environment? Consider the following simple ideas. Turn off electrical devices when they're not being used. Turning off, rather than leaving on stand-by, things like your TV and puter will save huge amounts of energy. With this, we can all help reduce the amount of carbon dioxide emitted into the earth's atmosphere, thereby reducing pollution and global warming. Share your ear. Rather than traveling to work alone, why not arrange ear-sharing with one or more of your,friends or colleagues? To give you an example, if you drive a fashionable ear, you will use more energy in a year than you would leaving your fridge open for seven years, or your TV on for thirty-two years ! Imagine the savings if you shared your ear with 2,3 or even 4 other people ! Refuse junk mail. While we all plain about how much junk mail we get, we very rarely do anything about it. The mail continues to go straight from our letter-boxes into the garbage bin--with 99% of it not even opened. What can you do about this? There are various websites where you can register to receive no junk mail. As well as saving time, you'll also be doing a lot for the environment. Each year,100 million trees are used to produce junk mail.250,000 homes could be heated with one day's supply of junk mail. There are many other everyday changes you can make to help the environment. They will cost you nothing, and many will actually save you money! Why not give it a try? We can all help,if we really want to.1.[不定向选择题]We shouldn't buy a car since it wastes so much energy.A.Right B.Wrong C.Not mentionedABC确定 2.[不定向选择题]Even if we want to make some changes to help the environment, we can do nothing.A.Right B.Wrong C.Not mentionedABC确定
