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。

 

5. In April, resident Hu inspected the warships in Qingdao, ________ the 60th anniversary of the founding of the PLA Navy.

A. marking               B. marked                 C. having marked      D. being marked

【解析】A。mark的意思是“标志”，由于其后带有宾语，所以不可能用过去分词或现在分词的被动形式，故可排除B和D；再从动作的先后顺序来看，应该是先有inspect，后才有mark，所以选A不选C。

 

6. The government plans to bring in new laws ________ parents to take more responsibility for the education of their children.

A. forced                  B. forcing                 C. to be forced          D. having forced

【解析】B。由于空格后跟有动词force的宾语，所以就不可能用过去分词或不定式的被动形式，故可排除A和C；再从句意来看，force并不是发生在主句谓语之前的动作，所以不宜用完成式。顺便说一句，如果选项中有不定式to force也可以选。

 

7. At the age of 29, Dave was a worker, ________ in a small apartment near Boston and ________ what to do about his future.

A. living; wondering  B. lived; wondering   C. lived; wondered    D. living; wondered

【解析】A。两空均填现在分词，用作定语修饰a worker。注意句中的并列连词and，用于连接两个相同的句子结构（即连接两个现在分词短语）。句意为：戴夫29岁时是一名工人，住在波士顿附近的一间小公寓，不知未来怎么办。

 

8. When we visited my old family home, memory came ________ back.

A. flooding               B. to flood                 C. flood                   D. flooded

【解析】A。此题考查come后接现在分词的用法。come doing有两个主要用法：一是表示与go doing方向相反的动作，二是表示“来”的方式。如：Why don’t you come ice-skating tonight? 今晚来溜冰好吗? She came running into the room. 她跑进屋来。
