Part Ⅰ.单句语法填空
在空白处填上适当的内容(1个单词)。
1．[2015·四川成都一诊]Gone are the days we spent time fishing and swimming in the unpolluted river.
答案：when 考查定语从句。从句中不缺少主语和宾语，且先行词表时间，因此填关系副词when。
2．[2015·重庆一中一诊]I'm glad to introduce Mr Smith to you, without consideration our project would have ended in failure.
答案：whose 考查定语从句。从句中缺少定语，指代Mr Smith's，故填whose。
