Question

11．More than l00，and possibly hundreds，of Antarctic icebergs are floating towards Now Zealand in a rare event which has prompted a shipping warning，officials said on Monday．
An Australian Antarctic Division glaciologist，said that th9 ice chunks（塊），spotted by satellite photography，had passed the Auckland Islands and were heading towards the main South Island，about 450 kilometers southeast of it．
    Scientist Neal Young said more than 100 icebergs，some measuring more than 200 meters across，were seen in just one cluster（串），indicating there could be hundreds more．He said they were the remains of a massive iceberg which split from the Antarctic as sea and air temperatures rise due to global warming．"All of these have come from a larger one that was probably 30 square kilometers in size when it left Antarctica，"Young told the reporter．"It's done a long circuit around Antarctica and now the bigger parts of it al e breaking up and producing smaller ones"
    He said large numbers of icebergs had not floated this close to New Zealand since 2006，when a number came within 25 kilometers of the coastline-the first such sighting since l931．"They're following the same tracks now up towards New．Zealand．Whether they make it up to the South Island or not is diffcu1t to tell，"Young said？
    Maritime New Zealand spokesman Ross Henderson said that New Zealand has already issued coastal navigation warnings for the area in the Southern Ocean Where the icebergs have been seen．The icebergs are smaller parts of the giant chunks seen off Australia's Macquarie Island this month，including one estimated at two kilometers and another twice the size of Beijing's"Bird's Nest"Olympic Stadium．
Young earlier said he expected to see more icebergs in the area if the Earth's temperature continues to increase．"If the current trends in global warming were to continue I would anticipate（預(yù)見）seeing more icebergs and the large ice shelves breaking up，"he said．

51．We call infer that Auckland Islands isB
A．to the east of the South Island   
B．to the south of the South Island
C．to the north of the South Bland  
D．to the west of the South Bland

A．these icebergs came from different areas in Antarctica
B．these icebergs will completely be melted in a short time
C．the biggest of the icebergs is 30 square kilometers in size
D．the icebergs or ice chunks al e breaking up all the way
53．From the text we learn thatC
A．floating icebergs once reached the South Bland in history
B．icebergs were over 25 kilometers from the South Bland in 2006
C．these icebergs are floating along almost the same coulee
D．floating icebergs were closest from the South Island in l 931
54．How does the government deal with the matter？B
A．Making good use of the icebergs．
B．Sending out safe sailing warnings．
C．Warning people to protect the environment•
D．Noticing the icebergs by satellite photography．
55．What is the main cause of icebergs floating north？A
A．Global warming     
B．The rising of sea level
C．The ocean current． 
D．The season wind．

Answer 1

分析 本文主要介紹了全球變暖引發(fā)的環(huán)境問題．南極冰川因氣溫的回升而沿著相同的路徑向新西蘭漂移，政府已經(jīng)向市民發(fā)出航行的警告．

解答 51．B．細節(jié)理解題．根據(jù)開頭第一句中 th9 ice chunks（塊），spotted by satellite photography，had passed the Auckland Islands and were heading towards the main South Island，about 450 kilometers southeast of it．可知，奧克蘭群島（Auckland Islands）在（新西蘭的） 南島的南邊；故選B．
52．D．細節(jié)理解題．根據(jù)第三度中Young told the reporter．"It's done a long circuit around Antarctica and now the bigger parts of it al e breaking up and producing smaller ones"可知，南極冰山的沿途冰山在一直融化，所以選擇D．
53．C．細節(jié)理解題．根據(jù)第四段及其中一句．"They're following the same tracks now up towards New．Zealand．可知，大量的冰川幾乎沿著相同的路徑向新西蘭漂移；故選C．
54．B．細節(jié)理解題．根據(jù)第五段開頭一句 Maritime New Zealand spokesman Ross Henderson said that New Zealand has already issued coastal navigation warnings for the area in the Southern Ocean Where the icebergs have been seen．可知，新西蘭政府已經(jīng)發(fā)出了因氣候變暖導致冰川融化帶來的潛在威脅以及航行的危險等警告信號；故選B．
55．A．推理判斷題．由第三段He said they were the remains of a massive iceberg which split from the Antarctic as sea and air temperatures rise due to global warming．"及文章末尾部分的描述可知，這一現(xiàn)象的出現(xiàn)主要是由于氣候變暖所導致的；故選A．

點評 考查學生的細節(jié)理解和推理判斷能力．做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確選擇．在做推理判斷題時不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
