　　17. For 12 years, Hu Liang, ________(move) to Finland after college graduation , has seen more and more Chinese tourists visiting the country to enjoy ________(watch) the winter pole light.

　　【答案解析】having moved; watching句意：胡亮大学毕业后迁居芬兰，12年来看到了越来越多的中国旅游者来芬兰享受观看冬季北极光的快乐。根据本句可知“迁移芬兰”先于“看到越来越多中国人来芬兰”，第一空填having moved;enjoy doing sth.为固定搭配，第二空填watching。

　　18. ________(know)which university to attend，the girl asked her teacher for advice.

　　【答案解析】Not knowing　句意：女孩不知道该上哪一所大学，所以她就向老师寻求建议。句子主语the girl和动词know之间是主动关系，因而应使用现在分词作原因状语;由句意可知，应使用现在分词的否定形式。

　　19. Shortly after suffering from a massive earthquake and ________(reduce)to ruins，the city took on a new look.

　　【答案解析】being reduced　句意：这座城市在遭受了一次强烈地震并被夷为废墟不久之后，呈现出了一种新面貌。分析句子结构可知，reduce和suffer并列于介词after之后，所以要用­ing形式。结合主语the city和动词reduce为被动关系，所以用动名词的被动形式。

　　20. Shanghai simplified the procedures for skilled foreigners ________(work) in the city to get residence permits within three days, the city’s latest measure ________(attract) overseas workers.

　　【答案解析】working; to attract上海为在本市工作的有技能的外国人简化了三天内申领居住证的程序，这是最新出台的吸引海外技工的措施。第一空填working修饰foreigners; 第二空填to attract，说明measure的具体内容。
