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。
