课时跟踪检测（一） Introduction & Reading — Pre-reading 阅读理解A2013 was a record­breaking year for rhinoceroses — but not in a good way. That year, a total of 1,004 rhinos were poached (illegally hunted) in South Africa, the country where almost all of the world's rhinos live. That's an increase of more than 50 percent from 2012 —when 668 rhinos were killed. It was also the most South African rhinos killed in one year.“The world's rhinos are facing great danger，” says Dr. Naomi Doak of TRAFFIC, a conservation group that works to stop the trafficking (buying and selling) of wildlife.The rise in poaching is due to an increasing demand for rhino horns in Asian countries such as Vietnam and China, where the horns are used as key ingredients in traditional Asian medi cines. Some people believe taking ground­up rhino horn can help treat pain, fevers, and cancer (though these uses have not been medically proven to be effective). The demand is so great that rhino horns can sell for more than$30,000 a pound in Asia.Poaching has already had extremely serious results for rhinos. The Western black rhino became extinct in the last ten years. The Javan rhinoceros has almost completely disappeared from Vietnam, with fewer than 50 remaining. Now, African black rhinos and white rh inos are facing disaster. The black rhino is listed as “highly endangered” by the International Union for Conservation of Nature. Fewer than 5,000 exist. White rhinos are considered “near threatened”， with about 20,150 in the wild.Many nations are now taking steps to protect rhinos. The governments of several countries have signed agreements to fight rhino poaching by making the sale of rhino horns illegal, catching poachers and smugglers (走私者)，and increasing public awareness about the problem.South Africa has signed agreements with Vietnam and China to fight wildlife trafficking between the countries. It is developing similar agreements with Mozambique，Thailand, Laos, and Cambodia.“These countries must join together if they hope to stop this stealing of southern Africa's natural heritage (遗产)，”says Tom Milliken, TRAFFIC's rhinoexpert.“Rhino­horn trafficking represents a threat to the basic structure of society.”语篇解读：本文是说明文。

B“Once there was the Stone Age, then the Bronze Age, and now we are in the middle of the Plastic Age，” said teenager Boyan Slat. “Every year, we produce 300 million tons of plastic. Much of it reaches our oceans.”At the age of 16, Boyan Slat scuba dived off Greece in the Mediterranean Sea seeing more rubbish floating on and under the surface. He said, “At first, I thought I was swimming through strange jellyfish. Instead, I swam through more plastic bags than fish.” Seeing all th e ocean trash, he asked himself，“Why not clean it up？”Slat quit his Aerospace Engineering studies to create www. theoceancleanup. com in order to fund his research on how to pick up all the plastic trash floating on the oceans of the world. Researchers discovered that 46, 000 pieces of plastic float on every square mile of the oceans, produced by billions of humans around the planet throwing their plastic into rivers, streams and directly into the oceans. What's worse, plastic does not break down.Today, we find plastic in the tissue of about every creature in the oceans. Additionally, millions of tons of plastic gather in giant ocean­going garbage patches (垃圾带). You may Google “The Great Pacific Garbage Patch”. It grows from 60 to 90 feet deep in places. It kills millions of sea birds, turtles, sharks, dolphins and whales.Being a brilliant, innocent teenager, Boyan Slat decided to construct designs of some equipment that would collect millions of tons of plastic floating on our oceans. He created a solar­powered trawler (拖网渔船) to pick up surface plastic, chew it up and store it in huge bins for collection. He also created floating booms (挡栅) that allow the oceans to sweep the plastic for efficient pick­up. When you see the designs, they will blow your mind.Boyan Slat stands at the head of his class in creating solutions for the folly of humans. If ever humans need leaders to stand up and be counted, we need more people like Boyan Slat to lead us out of damaging our planet home towards a biologically healthy future.语篇解读：16岁的Boyan Slat设计出了专门用于收集海洋塑料垃圾的设备，为保护海洋生态系统作出了杰出的贡献。
