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 slowed.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 －1.88 ℃ 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 －2.05 ℃.That small difference is enough for the fish to live at the freezing temperature of the icesalt 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 things 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. 【解題導(dǎo)語】　本文主要介紹了一種生活在南極海水中的魚。 1．What is the text mainly about? A．The terrible conditions in the Antarctic. B．A special fish living in freezing waters. C．The ice shelf around Antarctica. D．Protection of the Antarctic cod. 解析：選B。主旨大意題。本文主要講述了對一種能夠生活在南極冰冷的海水中的魚的研究，因此B項是文章的中心意思。 2．Why can the Antarctic cod live at the freezing temperature? A．The seawater has a temperature of －1.88 ℃. B．It loves to live in the icesalt mixture. C．A special protein keeps it from freezing. D．Its blood has a temperature lower than －2.05 ℃. 解析：選C。細節(jié)理解題。根據(jù)文中第五段的說明可以知道：正是這種特殊的蛋白質(zhì)使得這種魚在南極海水中生活而不至于被冰凍。 3．What does the underlined word“it”in Paragraph 5 refer to? A．A type of icesalt mixture. B．A newly found protein. C．Fish blood. D．Sugar molecule. 解析：選B。根據(jù)文中的敘述可以判斷出該物質(zhì)就是幫助這種魚生活在南極海水中的神奇的蛋白質(zhì)。 4．What does“glyco”in the underlined word“glycoprotein”in the last paragraph mean? A．Sugar. 　 B．Ice. C．Blood. D．Molecule. 解析：選A。詞義猜測題。根據(jù)“Because of its sugar content，it is called a glycoprotein．”這句話可以推斷出前綴“glyco”應(yīng)該和sugar有關(guān)。 Ⅲ.完形填空 When I began teaching in a university，I was invited to a workshop for new professors.I had __1__ a long time learning what to teach，but not learning how to __2__ it.Somehow，my university seemed to hope a weekend spent with experienced professors would __3__ for that.My colleagues presented wellcrafted(精心準(zhǔn)備的)lectures about the tools they used.I enjoyed their __4__，but did not remember a thing they said.
