At the underside of the shelf there lives a small fish, the Antarctic cod.For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a fortable place to work and research has been slow. Now it seems we have an answer.Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.The fish were taken from seawater that had a temperature of －℃and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to －℃. That small difference is enough for the fish to live at the freezing temperature of the ice－salt mixture.The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein(蛋白質(zhì)) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.Study showed that it is an unusual kind of protein. It has many small sugar molecules(分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has e to be called the antifreeze fish glycoprotein, or AFGP.49．What is the text mainly about?A. The terrible conditions in the Antarctica.B. A special fish living in freezing waters.C. The ice shelf around Antarctica.D. Protection of the Antarctic cod.50．Why can the Antarctic cod live at the freezing temperature?A. The seawater has a temperature of －℃B. It loves to live in the ice－salt mixture.C. A special protein keeps it from freezing.D. Its blood has a temperature lower than －℃51．What does the underlined word “it” in Paragraph 5 refer to?A. A type of ice－salt mixture.B. A newly found protein.C. Fish blood.D. Sugar molecule.52．What does “glyco－” in the underlined word “glycoprotein” in the last paragraph mean?A. sugar B. iceC. blood D. molecule[答案]本文是一篇說(shuō)明文，介紹了在南極地區(qū)的一種特殊的魚(yú)，這種魚(yú)特別能耐寒。根據(jù)Description部分中第一段第二句話(huà)可知，A項(xiàng)正確。be intended for“為……設(shè)計(jì)的，為……準(zhǔn)備的”，所以B項(xiàng)符合題意。47．B。通讀全文可知，本段沒(méi)有提到大眾對(duì)課堂教學(xué)的觀(guān)點(diǎn)。因此B項(xiàng)符合題意。45．B。The authors offer a research－based framework for classroom strategies that work with boys—and don’t disadvantage girls.DescriptionBoys’ education continues to be a focus of public anxiety among teachers. Concern about boys’ general education under－achievement and the impact this under－achievement has on the boys themselves, as well as on the broader society, continue to fuel disagreement and debate on the best approach to take in response.Teaching Boys provides a framework for developing practical and sustainable ways to improve boys’ education. The book indicates how what teachers do in the classroom can enable boys’ academic and social outes. With detailed case studies, Keddie amp。Teaching boys remains one of the most concerned issues in education today.B(2009主旨大意題。由文章最后一段內(nèi)容即可得出答案。43．B。42．A。因果判斷題。安徽)A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere, warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.In the past hundred years, humans have begun destroying rainforests in search of three major resources(資源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example, a lot of carbon dioxide(二氧化碳) in the air es from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections o
