新版教材解读与分析及复习方略指南 (一)职称英语复习策略 (二)2007年考题回顾与分析(以2006年考题作对比)
职称英语A, B, C三个等级的考试各由6个部分组成,每个级别的考试题型和题量均相同,但考试难度逐渐增加(语言难度增加, 考点设置难度增加)。 2007年职称英语各类A级考试出题特点如下:
小结:
段首句是观点句,因此很可能就是段落主题句。选项F(world’s worst disaster/世界上最严重的灾难)正好与该句内容呼应, F是答案。 (三)2008年教材变动情况 (难度B/A级/2008年理工类教材新增文章) The Tiniest Electric Motor in the World 1. Scientists recently made public the tiniest electric motor ever built. You could stuff hundreds of them into the period at the end of this sentence. One day a similar engine might power a tiny mechanical doctor that would travel through your body to remove your disease. 2. The motor works by shuffling(来回运动) atoms(原子) between two molten metal droplets(小滴) in a carbon nanotube(纳米管). One droplet is even smaller than the other. When a small electric current is applied to the droplets, atoms slowly get out of the larger droplet and join the smaller one. The small droplet grows – but never gets as big as the other droplet – and eventually bumps into the large droplet. As they touch, the large droplet rapidly sops up (吸入)the atoms it had previously lost. This quick shift in energy produces a power stroke(动力行程). 3.The technique exploits the fact that surface tension -- the tendency of atoms or molecules to resist separating -- becomes more important at small scales. Surface tension is the same thing that allows some insects to walk on water. 4.Although the amount of energy produced is small -- 20 microwatts(百万分之一瓦) -- it is quite impressive(给人印象深刻的) in relation to(与...相比) the tiny scale of the motor. The whole setup is less than 200 nanometers on a side, or hundreds of times smaller than the width of a human hair. If it could be scaled up to the size of an automobile engine, it would be 100 million times more powerful than a Toyota Camry’s 225 horsepower V6 engine. 5. In 1988, Professor Richard Muller and colleagues made the first operating(工作的, 运行的) micromotor(微型发动机), which was 100 microns(微米) across, or about the thickness of a human hair. In 2003, Zettl's group created the first nanoscale motor. In 2006, they built a nanoconveyor(纳米传送带), which moves tiny particles along like cars in a factory. 6.Nanotechnology(纳米技术) engineers try to mimic nature, building things atom-by-atom. Among other things, nanomotors could be used in optical circuits to redirect light, a process called optical switching. Futurists envision(预想) a day when nanomachines(纳米机器), powered by nanomotors(纳米发动机), travel inside your body to find disease and repair damaged cells. 练习: 1.Paragraph 2_______ 指定的四个段落都没有明显的段落主题句(2007年理工类A/B级概括大意题中四个指定段落都没有明显段落主题句),考生可以通过通读指定段落的大意来归纳出段落主题, 或借助一些有效的答题技巧确认段落主题。以确认段落第4段的段落主题为例分析答题技巧: A.An introduction of a Toyota’s 225 horsepower V6 engine. 2.Paragraph 4 ____. 4. Although the amount of energy(能量) produced is small -- 20 microwatts( 百万分之一瓦) -- it is quite impressive( 给人印象深刻的) in relation to(与...相比 )the tiny scale of the motor. The whole setup is less than 200 nanometers( 纳米) on a side, or hundreds of times smaller than the width(宽度) of a human hair. If it could be scaled up to the size of an automobile engine, it would be 100 million times more powerful(强大的) than a Toyota Camry’s 225 horsepower(马力) V6 engine. 2.B.解析:段落中没有明显的段落主题句, 但是段落中出现了大量反映典型细节信息的词语:20 microwatts(微瓦), 200 nanometers(纳米), hundreds of times smaller than the width of a human hair, 100 million times more powerful, 225 horsepower(马力), 这些细节信息贯穿全段,从性质上它们分别用于描述功率和尺寸大小, 因此可直接判断B(描述了纳米发动机的功率和尺寸大小)是答案。 提示:
如果段落中有明显的“细节信息词”, 可以考虑利用这些细节信息所反映的主题内容来确认段落主题。
(四)2008年考题预测分析
从2007年考题的出题情况和2008年教材的编写情况来看,2008年职称英语考试仍然将可能从教材中摘选一部分试题直接作为考题。2008年考题难度应该与2007年考题难度相当 |
