The scene in the Hollywood movie The Day After Tomorrow,when global warming could soon turn the global climate(气候)into a new ice age,may never occur，according to new research.The next ice age could be 15,000 years away,say European scientists who last month announced a continuous record of 740,000 years of climate data obtained from the Antarctic ice.Scientists from 10 nations have now almost completely drilled through a 3,000metre depth of ice high in the Antarctic mainland.They figure out that the area where summer temperatures can fall to 40，has at least 900,000 years of snowfalls，kept as neatly as the growth rings of a tree.And the ice and air caught in each layer(层)have begun to answer questions about the climates in the past.The results show that there have been eight ice ages in the past 740,000 years and eight warmer periods.And by comparing the pattern of global conditions today with those of the past,the researchers reported in Nature that the present warm period could last another 15,000 years.Research suggests that there is a very close connection between greenhouse gas levels and global average temperatures.It also shows that carbon dioxide levels are the highest for at least 440,000 years.“If people say to you:the greenhouse effect is a good thing because we would go into an ice age otherwise，our data say no，a new ice age is not hanging over our heads，”said Eric Wolff from the British Antarctic Survey.“Now we have eight examples of how the climate goes in and out of ice ages.and you can learn what the rules are that tell us about the future.”Scientists found that whenever temperatures rose in the frozen record,so did carbon dioxide level.“In 440,000 years we have never seen greenhouse gas get as thick as it is today，”said Dr Wolff.1In drilling through the ice in Antarctica,scientists have found that _.-4-Athe lowest temperature there is 40 Bthe depth of ice is 3,000 metres Cthe ice has existed for 15,000 years Dsnowfalls are kept in certain patterns 2The information of the global climate conditions in the past can be obtained through _.Aseparating carbon dioxide from the air Bexamining the growth rings of trees Ccomparing temperatures in different areas Dstudying the ice and air caught in each layer 3We can infer from Eric Wolffs words that _.Athere is something wrong with the data Bgreenhouse effect is always a bad thing Ca new ice age will not come in the near future Dgreenhouse gas will get thick in the future 4What would be the best title for the passage?AResearch over the Antarctic area.BWarm period to last about 15,000 years.CReport on the eight ice ages in the past.DHollywood movies and the global climate.答案与解析：1解析：细节理解题。第三段中“They figure out that the area where summer temperatures can fall to 40，has at least 900,000 years of snowfalls，kept as neatly as the growth rings of a tree.”说明科学家们发现，积雪保持着一定的模式。答案：D 2解析：细节理解题。根据第三段中“And the ice and air caught in each layer have begun to answer questions about the climates in the past.”可判断出对沉积在各层的雪和空气进行研究可以知道过去气候的状况。答案：D 3解析：推理判断题。根据倒数第二段艾瑞克沃尔夫说的“.a new ice age is not hanging over our heads.”可判断出，他认为新的冰川时代不会很快到来。答案：C 4解析：主旨大意题。阅读全文可知，本文主要叙述了作者对全球气候变化的观点以及对温室效应的态度。D 项明显偏离主题，可排除；A 项过于泛泛，没有提及气候问题；C 项只-5-是文章内容的一个侧面；只有 B 项适合用作标题。答案：B .七选五阅读 Are you truly happy?Do you ever know what it means to be happy and what it
