Question

一道高考英语阅读题

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 7. 40,000 years of climate data (数据) obtained from the Antarctic ice.

Scientists from 10 nations have now almost completely drilled through a 3,000-meter. 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 (二氧化碳) 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 oth.0pt 189.0erwise, 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 go into the climate models 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.

51题选什么，为什么选这个，我当时选了A，我觉得A最适合
51. What would be the best title for the passage?

A. Research over the Antarctic area.

B. Warm period to last about 15, 000 years.

C. Report on the eight ice ages in the past.

D. Hollywood movies and the global climate.

Answer 1

longinus 的 new age r帮你回答
首先A是肯定错的，AResearch over the Antarctic area是一个实验，是为了说明next ice age could be 15,000 years away 或者说是Warm period will be last
B应该是对了，整个前四段都是围绕着一句话来说明结论，推测和实验的。第五段是说二氧化碳浓度are the highest for at least 440,000 years （意还在说明温暖期的持续）第六段是为了说明new ice age is not hanging over our heads，and from data we can learn what the rules are that go into the climate models that tell us about the future.说明科学家对于这个理论是有理论依据的，这个理论就是温暖期的持续。最后一段说In 440,000 years we have never seen greenhouse gas get as thick as it is today 意思说是二氧化碳不会变稀薄（意思你明白）。所以全文还都是为让这个内容来写的。B应该是正确的
C如果文章的主旨是这个，那门文章应该叫实验报告
D相当于汉语课文里面开头引题的

Answer 2

答案为B.
从文章类型来说，在新闻报道类，研究调查报告类文章中，标题、中心等主旨大意类问题的答案一般都应该在第一段落寻找。第一段文章中research提醒文章类型，所以答案为B。
谢谢。

Answer 3

B 虽然研究都是在南极进行的，但是研究本身是和气温和冰川时代有关。

Answer 4

我会选 D.

我的看法是这是篇关于全球暖化的文章，由好莱坞大片做开篇，然后通过全球科学家提供的各项客观数据指陈出 新冰河纪的到临其实是遥不可及的。

其他选择都有点儿以偏概全。 B. 这选择也贴近内容，但我觉得有点儿过于武断。
