Last year, I decided to take a break and do some traveling.During my travel, I saw a lot of plastic waste in the ocean, and started wondering what I could do about it.I reused my bamboo bike, which I had made at the Bamboo Bicycle Club in Hackney, to float on the Thames and collect plastic on the river. On September 18, I started my journey at the source of the Thames in Lechlade.Every day was different and the first was the worst.It was raining hard and when I tried to put the bamboo bike in the water, the weight of it turned the whole thing over.I thought: This is it — the project is over! But after a good hour I managed to get it out. I had two fishing nets that I filled up every day with plastic, and I couldn't even collect everything because some bits were hidden under a forest of seagrass.I also took pictures and geotagged them, to map which parts of the river were the most polluted.Oxford was particularly bad, with a lot of takeaway boxes, bottles, DVDs and even some chicken breasts still in the plastic bags. My journey taught me the hard way that cleaning up the river is not going to solve the problem.We need to target the root cause: the buying of plastic.I'm thinking of running some activities in London and trying to make them spread quickly, like filling up a London bus with plastic bottles to represent how much plastic waste is produced every minute in London. I want to show people how plastic is affecting us: How some of it even comes back into our bodies via microplastics (塑料微粒) in fish or salt.I know you can't totally cut out the use of plastic, just like that, but I'd like people to think twice before buying their next bottle of water.Every step helps. 语篇解读：本文是一篇记叙文。文章讲述了作者休假旅行途中看到海洋上漂浮着很多塑料垃圾，于是开始骑着自己的竹制自行车在泰晤士河上捡塑料垃圾，保护环境的故事。 4．Why did the author make use of the bamboo bike again? A．It's comfortable to ride. B．It can float on the water. C．It can be used for exercise. D．It won't pollute the river. 解析：细节理解题。根据第一段中的“I reused my bamboo bike, which I had made at the Bamboo Bicycle Club in Hackney, to float on the Thames and collect plastic on the river.”可知，竹子做的自行车可以漂浮在水上，所以作者再次利用它。 √ 5．How did the author feel when the bamboo bike turned over? A．The project failed. B．The bike was gone. C．Everything would turn better. D．All the work was finished. 解析：细节理解题。根据第二段中的“I thought: This is it — the project is over！”可知，竹制自行车翻车的时候，作者认为这个项目失败了。 √ 6．Which is the closest in meaning to the underlined word “geotagged” in paragraph 3? A．Revised.　　　　　　 B．Cleared. C．Marked. D．Collected. 解析：词义猜测题。根据画线词前的“took pictures”以及下文的“to map which parts of the river were the most polluted”可知，作者拍下照片是为了绘制地图，标识出河流的哪片区域污染最严重。由此可推知，画线词与绘制地图有关，表示对垃圾多的地方进行标记。mark表示“做记号”，意思与之相近。 √ 7．What does the author think is more important to do with plastic pollution? A．Closing plastic factories. B．Reusing plastic items. C．Collecting plastic waste. D．Buying fewer plastic products. 解析：推理判断题。根据第四段中的“We need to target the root cause: the buying of plastic.”及最后一段中的“I know you can't totally cut out the use of plastic, just like that, but I'd like people to think twice before buying their next bottle of water.”可知，在作者看来，少购买塑料制品对减少塑料污染很重要。 √ Ⅱ.阅读七选五 Your carbon footprint is the amount of greenhouse gases that you produce as you live your life.In order to hold the global temperature rise to 2℃ or less, everyone needs to average an annual carbon footprint of 1.87 tons by 2050. 8 Eat lower on the food chain.This means eating mostly fruits, vegetables, grains, and beans.Meat and dairy are responsible for 14.5 percent of man-made global greenhouse gas emissions. 9 If you have no meat or dairy every day, you can reduce your carbon footprint by 8 pounds. 10 Fashionable, cheap items go out of style quickly and get dumped in landfills where they produce methane (甲烷) as they decompose.Currently, the average American gets rid of about 80 pounds of clothing annually.In addition, most fast fashion comes from Asia, so shipping it to the US requires the use of fossil fuels. Use low energy appliances.Replace traditional light bulbs with LED ones.Though LEDs cost more, they use a quarter of the energy and last up to 25 times longer.Make energy efficiency a primary consideration when choosing a new microwave, air conditioning unit, dishwasher, or refrigerator. 11 Choose green travel.An average car produces about five tons of carbon each year. 12 Take public buses, carpool, or bike to your destination when possible.This not only reduces CO2 emissions, but it also lessens traffic jams. A．Don't buy fast fashion. B．Never choose quality clothing. C．But people ignore this serious problem. D．Making changes in transport matters much. E．Here are ways to reduce your carbon footprint. F．They are mainly from food production and processing. G．Products with the ENERGY STAR sign have better efficiency. 语篇解读：本文是一篇说明文。文章介绍了减少个人碳足迹的方法。 8．解析：选E　根据上文“In order to hold the global temperature rise to 2˚C or less, everyone needs to average an annual carbon footprint of 1.87 tons by 2050.”可知，这是在介绍全球变暖问题和个人碳足迹的目标。下文介绍了具体方法，故E项(以下是减少碳足迹的方法)承上启下，符合语境。 9．解析：选F　根据上文“Meat and dairy are responsible for 14.5 percent of man-made global greenhouse gas emissions.”可知，肉类和乳制品对温室气体排放有显著影响。F项(它们主要来自食品生产和加工)解释了肉类和乳制品对温室气体排放有很大影响的原因，符合语境。 10．解析：选A　根据下文“Fashionable, cheap items go out of style quickly and get dumped in landfills where they produce methane as they decompose.”可知，这是在介绍快时尚商品的快速更迭及其对环境的影响。故A项(不要购买快时尚)引出了下文解释的原因，符合语境。 11．解析：选G　根据上文“Make energy efficiency a primary consideration when choosing a new microwave, air conditioning unit, dishwasher, or refrigerator.”可知，选择电器时应优先考虑能效。故G项(带有ENERGY STAR标志的产品效率更高)承接上文，符合语境。 12．解析：选D　根据上文“An average car produces about five tons of carbon each year.”可知，汽车的碳排放量较高。下文介绍了乘坐公交车、拼车或骑自行车等方式，故D项(改变交通方式非常重要)承上启下，符合语境。 本课结束 更多精彩内容请登录：www.zghkt.cn 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 ， but much less time for paper.Because of this, people think paper bags are the better environmental choice. However, 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. 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. This happens because electricity “off”. To make sure your appliance is in fact off, remove the plug from its power supply. $
