fill it with creatures (生物) from the earth.This idea may sound like something from a science fiction (科幻小说)，but it is actually being taken seriously by many researchers.This suggests the future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week.Leading researchers as well as science fiction writers will attend the event.Turning Mars into a little earth has long been a topic in science fiction，” said Dr Michael Meyer，NASAs senior scientist for astrobiology (太空生物学)“Now，with scientists exploring the reality，we can ask what are the real possibilities of changing Mars.”Most scientists agree that Mars could be turned into a little earth，although much time and money would be needed to achieve this goal.But many experts are shocked by the idea.“We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet，” said Paul Murdin from the Institute of Astronomy，Cambridge，UK.Over the past months，scientists have bee increasingly confident.They will find Martian life forms.Europe and Americas robot explorers have found proof that water，mixed with soil，exists in large amounts on the planet.11The passage is about .AMars supporting lifeBfinding water on the Mars Ca plan turning Mars into a little earthDthe necessity of changing Mars答案C解析主旨大意题。根据文章大意和文章第一段的“The plan：turn Mars into a blue world with streams and green fields，and then fill it with creatures (生物) from the earth.”可知，文章主要介绍了一个把火星变成地球的计划，故选C。12Those who agree to

from the land of Antarctica，a huge shelf of ice meets the ocean.At the underside of the shelf there lives a small fish，the Antarctic cod(鳕鱼)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 the 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 fishs 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 fishs blood kept it from freezing.Their search led to some really strange things made up of a protein(蛋白质) 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.15What is the text mainly about?AThe terrible conditions in the Antarctic.BA special fish living in freezing waters.CThe ice shelf around Antarctica.DProtection of the Antarctic cod.答案B解析主旨大意题。本文主要讲述了对一种能够生活在南极冰冷的海水中的鱼的研究，因此B项最能概括文章的中心意思。16Why can the Antarctic cod live at the freezing temperature?AThe seawater has a temperature of 1.88.BIt loves to live in the icesalt mixture.CA special protein keeps it from freezing.DIts blood has a temperature lower than 2.05.答案C解析细节理解题。根据文中第五段的说明可以知道：一种特殊的蛋白质使得这种鱼在南极海水中生活而不至于被冰冻。17What does the underlined word “it” in Paragraph 5 refer to?AA type of icesalt mixture.BA newly found protein.CFish blood.DSugar molecule.答案B解析代词指代题。根据文中的叙述可以判断出该物质就是帮助这种鱼生活在南极海水中的神奇的蛋白质。.语法填空The Million Pound Bank Note is based on a short story 18.written(write) by Mark Twain，who was brought up in Hannibal，Missouri，and is best
