A
An introduction of a Toyota’s  225 horsepower V6 engine.
B
A description of the nanomotor in terms of power and size.
C
Surface tension(表面张力).
D
Previous inventions of nanoscale(纳米级的) products.
E
The working principle of the nanomotor.
F
Possible fields of application in the future.
 

  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.
B
A description of the nanomotor in terms of power and size.
C
Surface tension(表面张力).
D
Previous inventions of nanoscale(纳米级的) products.
E
The working principle of the nanomotor.
F
Possible fields of application in the future.
 
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。
