必修 2　 Unit 4 Wildlife protection Ⅰ.阅读理解 A On a college camping trip, curiosity about waves and sand caused Rob Thieler to study shorelines around the world. Thirty years later and now a US Geological Survey research geologist, Thieler, is combining science and smart phone technology to help study an endangered bird, the Atlantic coast piping plover. The piping plover is a shorebird that breeds(繁殖) along the Atlantic coast, the Great Lakes and the Great Plains. Rising sea level associated with climate change, as well as increased development in their beach habitats(栖息地), threatens the species(物种). To help track changes in piping plover habitats, Thieler developed a free app called iPlover in 2012. This is a marked change from the typical way scientists collect data, which involves gathering information using specialized equipment or writing in notebooks and then putting into spreadsheets. Since releasing iPlover, scientists have gathered data across 1500 km of breeding range. That equals about a third of the distance across the US, which is a large area to cover for only two thousand breeding pairs of piping plovers on the East Coast. Instead of having to travel and spend days at each site, a number of cooperators in the field use the app to collect and send data, allowing scientists to gather data more efficiently. It also allows them to collect data at the same time during each breeding season, providing a better picture of changes that happen over longer periods of time. And fast, centralized access means scientists can look at data quickly to get a real-time idea of where and how piping plovers are using their habitats. While iPlover is used by trained field staff, other apps like the US Geological Survey￿s Web-based “iCoast—Did the Coast Change?” invite citizen scientists to identify coastal changes by comparing bird￿s-eye-view photographs taken before and after storms. All the information scientists and citizen scientists alike collect helps federal and state agencies create policy plans for addressing climate change impacts (影响) worldwide. 1. What can we know about the piping plover? A.Its behaviour is changing. B.Its habitat is growing bigger. C.Its living environment is becoming worse. D.Its breeding is limited to the Atlantic coast. 2. Why did Thieler develop iPlover? A.To study shorelines across America. B.To advance information technology. C.To find out global climate change. D.To monitor changes of piping plover habitats. 3. Which of the following benefits the shorebirds? A.The camping equipment. B.Research on smart phones. C.The changeable coast. D.Progress in technology. 4.What would be the best title of the text? A.Protecting endangered shorebirds B.Rob Thieler, a creative scientist C.iPlover, tool for training field staff D.Differences between iPlover and iCoast B Fikiri Kiponda￿s path from accountant to marine (海洋的) conservationist was sparked by a chance encounter. After securing his dream job, Kiponda decided he wanted more. He wasn￿t quite sure what he was looking for until he ran across some turtle hatchlings. He didn￿t know it was turtle. Fortunately enough he got the right person to ask and he got motivated. That person was Nkindi, a staff member at the Watamu Conservation Project who later invited him to volunteer on the project. He later left his accounting job and fully devoted himself to the world of sea turtles. Now,he runs and spends his time nursing critically endangered sea turtles back to health. Sea turtles have been around for nearly 110 million years and are now considered highly endangered. Their preservation rests on activities of conservationists such as Kiponda as these turtles face numerous threats and signs of their extinction in the next 50 years. Local fishermen traditionally catch them to supplement their own low catch rates and sell them for their oil. As changes are made to accommodate more hotels for tourists, there is less available beach land for turtle nesting. Kiponda￿s passion has now spread to his community, changing their attitude towards sea life preservation with his “bycatch release programme”. Through this programme, fishermen are now paid for returning turtles accidentally caught in their fishing nets. The healthy ones are tagged and released into the marine park while he takes care of sick and injured turtles back to health. Before the launch of pioneering spirit like this, turtles caught by fishermen were used for their meat and their oil extracted(提炼) for their medicinal properties. “ Releasing the turtle back into the ocean is a very good feeling, like, you feel like you￿ve done something concrete and I guess everybody would love to do that…so I guess it￿s unique work.” 5. What was Fikiri Kiponda￿s dream job according to the text? A.An accountant. B.A marine conservationist. C.A guide to the Watamu Conservation Project. D.An advocate for turtles. 6. What may be the main threat to the turtles? A.The rising sea level. B.Being caught by tourists. C.Overdevelopment in the tourism. D.The reduction in their nesting place. 7. Which of the following words can best describe Fikiri Kiponda? A.Energetic but conservative. B.Enthusiastic and caring. C.Arbitrary but considerate. D.Ambitious and knowledgeable. 8. Which of the following can be the best title for the text? A.The man saving endangered sea turtles B.An unique job of protecting sea turtles C.A pioneering project protecting sea animals D.The current situation faced by sea turtles Ⅱ.语法填空 阅读下面短文,在空白处填入 1 个适当的单词或括号内单词的正确形式。 Throughout history, people have thought of the ocean as a diverse and limitless source of food. Yet today there is clear evidence that the oceans have a limit. Most of the big fish in our oceans are now 1.　　　　 (go). One major cause is overfishing. People are taking so many fish from the sea that many species cannot replace 2.　　　　(they). For centuries, local fishermen caught only enough fish for their own and their community￿s needs. However, from the early 20th century, people around the world became interested 3. 　 　 　 　 consuming protein-rich foods. People began 4.　　　　 (catch) large quantities of fish for profit and selling them to worldwide markets. In a very short period of time, commercial fishing 5.　　　　(great) reduced the number of large predatory fish, such as cod and tuna. Today, there are still plenty of fish in the sea, 6. 　　　　they￿re mostly just the little ones. Small fish, 7. 　 　 　 　 include sardines and anchovies, have more than doubled in number—largely because there are not enough big fish 8.　　　　 (eat) them. Such large fish 9.　　　　 (be) necessary, because they hunt and kill the sick and weak smaller fish. Without this weeding out, or the survival of the fittest, ecosystems become less stable. As a result, fish are less able to survive 10. 　 　 　 　 (difficult) such as pollution, environmental change, or changes in the food supply. Ⅲ.短文改错 Among the four seasons in a year, summer is my favourite, that makes me free, excited and energy. When summer vacation came every year, we can do all that we can￿t do during our school time, go shopping with friends, swimming in warm water and even hiking and camping in the deep valleys. These activities lead me to enjoy full free. We can find us in an exciting world every day, with the sun shining bright, trees growing better and flowers coming out of with all kinds of colours. Summer makes me full of energy and we feel I have the strength to do most difficult things in my life. I like summer better, and what about you?
