Ⅰ.单句语法填空
1．(2019·全国卷Ⅱ)Picking up her “Lifetime Achievement” award，proud Irene declared (declare) she had no plans to retire from her 36yearold business.
解析：首先确定该动词为主句的谓语动词；其次根据宾语从句的谓语动词had以及上下文的时态等为一般过去时，故该谓语动词应使用一般过去时；最后，主语和谓语动词之间构成主动关系。
2．(2019·北京卷)On the first day of my first grade，I stood by the door with butterflies in my stomach. I voiced (voice) my biggest concern to my mother.
解析：考查动词的时态。本句叙述的是过去的事情，用一般过去时，故填voiced。
3．(2019·北京卷)Does the name of the college you attend really matter？Research on the question suggests/suggested/has_suggested (suggest) that，for most students，it doesn't.
解析：考查动词的时态。本文的主题时态是一般现在时，主语是research，可以用suggests；又可以表示“研究已经表明了”，用现在完成时，可以填has suggested；又可以表示“研究过去表明了”，可以用一般过去时，填suggested。
