考查现在分词的典型考题
1. ________ many times, he finally understood it.
A. Told B. Telling C. Having told D. Having been told
【解析】D。根据句意可知，句子主语he与动词tell之间为被动关系，所以可以排除选项B和C；又因为tell与understand之间明显的先后关系，即先被告诉然后才明白，所以选D不选A。又如：Having been told so beforehand, he was not surprised. 因为之前已经有人告诉他了，所以他并不惊讶。
2. They use computers to keep the traffic ________ smoothly.
A. being run B. run C. to run D. running
【解析】D。此题考查keep…doing sth结构，其意为“保持……做某事”“使……不停地做某事”。又如：He kept the fire burning. 他让火燃着。I’m sorry to have kept you waiting. 对不起让你等了。
3. There is a great deal of evidence ________ that music activities engage different parts of the brain.
A. indicate B. indicating C. to indicate D. to be indicating
【解析】B。从语法上看，“there be+名词”后面既可接不定式，也可接现在分词，其区别是：用不定式表示将要发生的情况，和现在分词表示正在进行的情况或通常性情况。根据句意，显然应用现在分词。句意为：有大量证据表明音乐活动与大脑的不同部位有密切关系。
4. A small plane crashed into a hillside five miles east of the city, ________all four people on board.
A. killed B. killing C. kills D. to kill
【解析】B。现在分词短语killing all four people on board在此用作结果状语。又如：He fired, killing one of the passers-by. 他开枪了，打死了一个过路人。I fell, striking my head against the door and cutting it. 我摔了个跟头，头撞在了门上，划了个口子。
