答案與題解：
1. 文章標(biāo)題分析：El Nino （厄爾尼諾現(xiàn)象）來(lái)源：考試大
While （while的出現(xiàn)暗示作者要表達(dá)的真正意圖在后面的分句中）some forecasting methods had limited SUCCESS predicting the 1997 E1 Nino a few months in advance，the Columbia University researchers say their method call predict large E1 Nino events up to two years in advance．That would be good news for governments，farmers and others seeking to plan for the droughts and heavy rainfall that El Nino can produce in various parts of the world. Using a computer the researchers matched sea-surface temperatures to later El Nino occurrences between 1980 and 2000 and were then able to anticipate E1 Nino events dating back to1857, using prior sea．surface temperatures．The results were reported in the latest issue of the journal Nature．
The researchers say their method is not perfect, but Bryan C．Weare．a(chǎn) meteorologist at the University of California, Davis，who was not involved in the work，said it“suggests‘E1 Nino is indeed predictable．”
“This will probably convince others to search around more for even better methods．”said Weare．He added that the new method“makes it possible to predict El Nino at 1ong lead times．” Other models also use sea-surface temperatures, but they have not looked as far back because they need other data，which is only available for recent decades，Weare said．
The ability to predict the warming and cooling of the Pacific is of immense importance’．The 1997 El Nino，for example，caused an estimated$20 billion in damage worldwide，offset by beneficial effects in other areas，said David Anderson，of the European Centre for Medium．Range Weather Forecasts in Reading England．The 1877 El Nino，meanwhile，coincided with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China。prompting the development of seasonal forecasting，Anderson said．
When El Nino hit in 199 1 and 1997．200 million people were affected by flooding in China alone．a(chǎn)ccording to a 2002 United Nations report．
While predicting smaller E1 Nino events remains tricky．the ability to predict larger ones should be increased to at least a year if the new method is confirmed．
E1 Nino tends to develop between April and June and reaches its peak between December and February．The warming tends to last between 9 and 1 2 months and occurs every two to seven years·
The new forecasting method does not predict any major El Nino events in the next two years, although a weak warming toward the end of this year is possible．
分析：文章主要是在討論對(duì)厄爾尼諾現(xiàn)象進(jìn)行預(yù)測(cè)。
2. 直接解題：
1．The method used by the Columbia University researchers can predict E1 Nino a few months in advance．
A．Right B．Wrong C．Not mentioned
B．分析：該句中涉及到的信息較多，因此對(duì)句子內(nèi)容進(jìn)行分層劃分：劃分成3層：The method used by the Columbia University researchers + can predict E1 Nino + a few months in advance，同時(shí)利用句子中的特征詞Columbia University researchers 和a few months in advance作為答案線索，這樣發(fā)現(xiàn)答案相關(guān)句：
While some forecasting methods had limited SUCCESS predicting the 1997 E1 Nino a few months in advance，the Columbia University researchers say their method call predict large E1 Nino events up to two years in advance．（信息1和信息2的內(nèi)容都與文章內(nèi)容一致，但信息3說(shuō)“提前幾個(gè)月”，而原文說(shuō)“最遠(yuǎn)能提前到兩年”，因此可見(jiàn)問(wèn)題句的內(nèi)容中有與原文不一致的地方，因此判斷該句“不正確”。）
2. The Columbia University researchers studied the relationship between the past EI Nino occurrences and sea—surface temperatures．
A．Right B．Wrong C．Not mentioned
來(lái)源：考試大
A．分析：考慮把句子的內(nèi)容分成兩層信息：The Columbia University researchers studied + the relationship between the past EI Nino occurrences and sea—surface temperatures， 利用句子中出現(xiàn)的核心結(jié)構(gòu)EI Nino occurrences 和 sea—surface temperatures作為答案線索，這樣發(fā)現(xiàn)答案相關(guān)句：
While some forecasting methods had limited SUCCESS predicting the 1997 E1 Nino a few months in advance，the Columbia University researchers say their method call predict large E1 Nino events up to two years in advance．That would be good news for governments，farmers and others seeking to plan for the droughts and heavy rainfall that El Nino can produce in various parts of the world.
Using a computer the researchers matched sea-surface temperatures to later El Nino occurrences between 1980 and 2000 （該劃線結(jié)構(gòu)的含義揭示信息2正確，還需要對(duì)信息1進(jìn)行判斷--辨別the researchers是否就是“The Columbia University researchers”，而前文中出現(xiàn)的就是“The Columbia University researchers”，因此判斷信息1和信息2的內(nèi)容都在原文中有呼應(yīng)的內(nèi)容，因此判斷該句的說(shuō)法正確。）and were then able to anticipate E1 Nino events dating back to 1857, using prior sea-surface temperatures．
3. The Columbia University researchers are the first to use sea-surface temperatures to match the past EI Nino occurrences．
A．Right B．Wrong C．Not mentioned
來(lái)源：考試大
C．分析：該題涉及到的內(nèi)容和前面出現(xiàn)的問(wèn)題有關(guān)，注意到題干中出現(xiàn)的特征詞（the first），因此判斷對(duì)該詞的確認(rèn)是關(guān)鍵。利用該詞作為答案線索，這樣發(fā)現(xiàn)文章中沒(méi)有這個(gè)詞出現(xiàn)。因?yàn)樵摼涫歉爬偨Y(jié)句，因此再利用句子出現(xiàn)的核心結(jié)構(gòu)sea-surface temperatures 和the past EI Nino occurrences作為答案線索，發(fā)現(xiàn)涉及這兩個(gè)結(jié)構(gòu)的句子所表達(dá)的句意都與問(wèn)題句的內(nèi)容無(wú)關(guān)，因此判斷問(wèn)題句的說(shuō)法“沒(méi)提到”。

“This will probably convince others to search around more for even better methods．”said Weare．He added that the new method“makes it possible to predict El Nino at 1ong lead times．” Other models also use sea-surface temperatures, but they have not looked as far back (as the new method) because they need other data，which is only available for recent decades，Weare said．

4. Weare’s contribution in predicting E1 Nino，was highly praised by other meteorologists．
A．Right B．Wrong C．Not mentioned
來(lái)源：考試大
C． 分析：可以把題干的內(nèi)容劃分成2層信息：Weare’s contribution in predicting E1 Nino+ was highly praised by other meteorologists， 利用句子中出現(xiàn)的特征詞Weare作為答案線索，這樣發(fā)現(xiàn)答案相關(guān)句：

5. According to a Chinese report，the flooding in China caused by E1 Nino in 1 99 1 and 1 997 affected 200 million Chinese people．
A．right B．Wrong C．Not mentioned
B．分析：可以把句子中的信息劃分成3層：According to a Chinese report + the flooding in China caused by E1 Nino in 1 99 1 and 1 997 + affected 200 million Chinese people， 同時(shí)利用句子中出現(xiàn)的特征詞Chinese report， in 1 99 1 and 1 997和200 million Chinese people作為答案線索，這樣發(fā)現(xiàn)答案相關(guān)句：
When El Nino hit in 199 1 and 1997, 200 million people were affected by flooding in China alone(信息2和信息3在該劃線句中都有呼應(yīng)的內(nèi)容), according to a 2002 United Nations report．（該句的內(nèi)容與信息1的內(nèi)容不一致。）

6. It takes about eight months for El Nino to reach its peak．
A．right B．Wrong C．Not mentioned
來(lái)源：考試大
A． 分析：該問(wèn)題句內(nèi)容和結(jié)構(gòu)都較簡(jiǎn)單，句子中出現(xiàn)了一個(gè)數(shù)字（8個(gè)月），因此猜測(cè)對(duì)于這個(gè)數(shù)字的辨別是解題的關(guān)鍵。借助eight months 和句子中的核心詞peak作為答案線索，這樣找到答案相關(guān)句：
E1 Nino tends to develop between April and June and reaches its peak between December and February（借助該句含義可以推出“El Nino需要大約8個(gè)月達(dá)到峰值”）．The warming tends to last between 9 and 1 2 months and occurs every two to seven years· （這一劃線句是干擾句，該句講述的是El Nino的持續(xù)時(shí)間，而不是從產(chǎn)生到峰值的時(shí)間）
7. A special institute has been set up in America to study E1 Nino．
A．Right B．Wrong C．Not mentioned
C．分析：句子內(nèi)容也是較為簡(jiǎn)單，因此直接把這個(gè)句子看成是1層信息。利用句子中出現(xiàn)的核心詞A special institute 和 America作為答案線索，這樣發(fā)現(xiàn)文章中根本就沒(méi)有提到“在美國(guó)建立一所特別的研究院”，因此該句為“沒(méi)提到”。
