Unit 4 Global warmingⅠ.阅读理解A(2017·山东济南高三高考模拟考试)Thrift stores are a refuge (避难所) for countless items from landing in garbage piles. Value Village, for example, saves more than 650 million pounds of clothing from landfills (垃圾填埋场) each year, making it one of the largest recyclers of used garments in the world. Their stores give a second life to 1.8 million pounds of clothes every day, which is equal to 600 mid­sized cars. Almost 100 percent of clothing and textiles are recyclable, yet 85 percent of them end up in landfills. It's estimated that the average person throws away 70 pounds of clothing a year.Lindsay Coulter is the so­called “Queen of Green” with the David Suzuki Foundation, educating people on how to live a greener life by making changes around the house. She says that donating or shopping at thrift stores is an excellent way to exercise all three of the three R's：reduce, reuse and recycle. She says, “Whether it's a purse or a pair of shoes, it's really worth considering going to thrift stores as another point of contact to help reduce your consumption.”Coulter points out that since landfills are airtight, textiles take longer to break down. “I'd imagine things like an old towel, a rag or an old T­shirt will last a really long time，”she says. T he beauty of thrift shopping is that the supply is neverending, so if you don't find what you're looking for one day, it's likely to show up in no time.One person who knows this quite well is Jodi Jacyk, costume specialist in the Department of Theatre and Film at the University of British Columbia. She says the majority of items for the university's productions are purchased second­hand. Because of her shrinking budget, items like clothing and shoes are thrifted from Value Village. “We are constantly thri fting and we reuse costumes for many years. Thrift shopping is a much easier, cheaper way to do things，”she says.The next time you need to lighten your closet, take the opportunity to go thrift shopping to lighten both your carbon footprint and your financial burden at the same time.【解题导语】本文主要介绍了一种环保的生活方式，即去慈善商店捐或购买二手衣物。

B(2017·山东济南高三高考模拟考试)People need to seek out new foods because the world has so many mouths to feed. As of 2015, there are more than seven billion people on Earth, according to the United Nations. And by 2100 that number may double. Feeding all of these people means not only improving the way foods are grown, but also finding new sources of nutrition.And that_quest is becoming ever more urgent. If nothing changes, within 35 years, the world's appetite will be greater than the amount of foods produced. That's according to a report released last year. It was prepared by the Global Harvest Initiative, a private agriculture group based in Washington, D. C.Global warming, too, is changing food production. Scientists predict that rising temperatures will reduce the growth of important crops like wheat, corn and soybeans. Low­income developing countries will be hit the hardest. When harvests fall, crops become more expensive. And since those foods are also used to feed animals like cows and pigs, meat prices, too, will rise.All over the world, researchers are racing against the clock to figure out how best to feed more people in a fast­changing world. And some surprising ideas have begun to come up. Two years ago, scientists introduced the first burger made from meat grown in a lab. The project cost more than $ 300, 000, but it's a start. Other researchers are developing seeds that can survive high temperatures and drought. Still others are finding ways to improve the genes of meat animals so they produce more meat and can stand the heat.A gloomy (悲观的) forecast for the planet isn't the only reason to study foods for the future. It's a creative quest that will inspire people who can think in new ways about existing plants and animals —even insects. These researchers have used their talents in ways that even they never would have predicted.【解题导语】本文主要讲的是在全球变暖的环境下，人们应如何应对日益膨胀的人口的温饱问题。
