3用不同技巧
为了提高阅读速度，应学会运用略读法，通篇浏览，了解大意，领会文章的主要内容，必要时还可以采用寻读法，有目的地寻找文章的重要信息。在遇到but，however等转折词时，下句的意思肯定与上句相反，可稍加留意；当so，therefore等连词出现时，这就意味着段落的中心句可能落在此处，需要特别留意其中的关键词和主要信息。当遇到上下句子之间有and，or等表示顺延意思的连词时，可以一带而过。在阅读问题和选择项时，应该仔细品味各项的含义、它们之间的意思差别以及它们与原文中相关句子或段落意义的异同。有时候，这些差别是细微的。然而，通过仔细对比是可以分辨出来的，那个与所提问题内容针对性较强的选择项往往就是正确答案。例：
Magnetic levitation vehicles，or maglev vehicles，will play an important role in the future of transportation，according to a report by Argonne National Laboratories．But before maglev vehicles can become a commercial success，the report says，people need to stop thinking of them as high-speed trains．Instead，consider them low-flying aircraft． Argonne contends that maglev will be best suited to replace commuter aircraft．Plane flights under 600 miles are the least energy-efficient，and maglev“planes“should cut these fuel needs by up to 75 percent． Therefore，the next decade could see commuters speeding to work at about 300 miles per hour aboard magnetic levitation vehicles．
1．Argonne believes that people should regard maglev transportation as ．
A）safe，efficient，high-speed trains
B）the most exciting form of transportation for the future
C）a kind of aircraft
D）the most economical form of transportation
2．Why could maglev trains replace short-flight commuter aircraft？
A）Maglev trains are faster．
B）Maglev trains are cheaper．
C）Maglev trains are more fuel-efficient．
D）Maglev trains are safer．
3．According to the passage，when could people start using a maglev commercially？
A）In 5 years．B）In 10 years．
C）In 20 years．D）In more than 5 years．
4．What is the best title for this passage？
A）The Future of Transportation
B）Argonne Develops Maglev Train
C）The Disadvantages of Commuting by Airplane
D）Commuting in the Future
答案：1．C）2．C）3．B）4．D）
分析：该试题讲的是磁悬浮列车。第二句的But表示转折。紧接在Instead句中，人们将maglev transportation看成是一种交通工具，与第一题答案吻合。原文第五句说明了为什么maglev trains能替代飞机，涉及第二题答案C）。最后Therefore后面的句子涉及到第三、四题答案。
