Findings suggest that these plants could help repopulate regions exposed by melting icecaps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.‎ Samples of the mossplant，covered by the glacier during the Little IceAge of 1550 to 1850 AD，were replanted in a lab at the University of Alberta and grew new stems. Researchers now think these findings can give indications to how regions can recover as the ice covering them melts.‎ Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many are as of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little IceAge between 1550 and 1850 AD can now be studied，including many species that have never been studied before.‎ While examining an exposed area of land，La Farge and her team discovered a small area of moss called Aulacomniumturgidum. It is a type of bryophyte(苔藓类植物) plant that mainly grows across Canada，the US and the Highlands of Scotland.‎ Dr La Farge noticed that the moss had small patches of green stems，suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC，“When we looked at the samples in detail and brought them to the lab，I could see some of the stems actually had new growth of green branches，suggesting that these plants are growing again，and that blew my mind. ‎ When we think of thick areas of ice covering the landscape，we’ve always thought that plants have to come from refugia(濒绝生物保护区)，never considering that land plants come from underneath aglacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world；we don’t know it all.”‎ Dr La Farge took samples of the moss and，using carbondating techniques，discovered that the plants date back to the Little IceAge. Dr La Farge’s team took the samples，planted the mind is hes full of nutrientrich potting soil and fed them with water.‎ The samples were from four separate species including Aulacomniumturgidum，Distichiumcapillaceum，Encalyptaprocera and Syntrichiaruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.‎ However，Dr La Farge was surprised that the plants buried underice have survived into the twentyfirst century. Her findings appear in proceedings(论文集) of the National Academy of Sciences.‎ ‎36.Dr LaFarge’s research is of great importance to_______________.‎ A.knowing what the plants during the Little IceAge were like B.understanding how ecosystems recover from glaciers C.regrowing many species that have been destroyed before D.figuring out the effects of melting icecaps on moss 答案　B 解析　推理判断题。根据第二段中的“Findings suggest that these plants could help repopulate regions exposed by melting ice caps.”可知，La Farge博士的研究对理解生态系统如何从冰川中恢复过来很重要。故选B。‎ ‎37.The underlined part“blew my mind”in Paragraph 6 can best be replaced by“________”.‎ A.surprised me B.greatly frightened me C.put my doubt out of my mind D.wasexactlywhatIhadinmymind 答案　A 解析　词义猜测题。根据第六段中的“I could see some of the stems actually had new growth of green branches，suggesting that these plants are growing again，and that blew my mind.”可知，划线部分意思是“出乎我的意料”，只有A选项符合语意。‎ ‎38.According to the passage，Aulacomniumturgidum__________.‎ A.lives better in small groups B.is very active in hot weather C.is strong enough to survive coldness D.is chosen from Canadian refugia 答案　C 解析　细节理解题。根据第五段及第八段中的“Bryophytes can survive long winters and regrow when the weather gets warmer.”可知，Aulacomnium turgidum是苔藓类植物中一种，因此也可在寒冷中存活。故选C。‎ ‎39.What’s the main idea of this passage?‎ A.Bryophyteecology is greatly affected by climate change.‎ B.400yearoldmoss’s survival is a mystery to solve.‎ C.Moss in ancient times was discovered in Canada.‎ D.400yearold plants were brought back to life.‎ 答案　D 解析　主旨大意题。根据文章内容可知冰封400年的植物也可以在适合温度中再次复活。故选D。‎
