After a day’s hard work I went to bed early than usual. It was about two o’clock in the morning when I was awakened by a big noise. I got out of the beds and slowly went upstairs. There was a light in the living room. I listened to carefully and heard two men speak quietly. I believed my house had broken into and I was really frightening. I went back upstairs and immediately call the police. You can imagine how embarrassed I was when they came upstairs but told me they had turned the television off for me and something was all right. early→ earlier

(答案→)early→ earlier
解析：辛苦工作了一天后，我比平常早一些上床睡觉。大约在凌晨2点时被惊醒。我慢慢上了楼。听到两名男子小声说话。我相信有人闯进了我的房子，真吓人。我立即打电话报警。你可以想象他们告诉我他们已经关闭电视时，我是多么尴尬。
【小题1】 根据后面的than usual 可以看出前面应该用比较级，故early→ earlier。
【小题2】 前面的主语是I, 后面的名词用单数形式，故beds→ bed。
【小题3】 由生活常识卧室一般在楼上，以及文章后面作者回到楼上和警察上楼告诉作者真相可知，此处作者是下楼，故upstairs→ downstairs。
【小题4】listen to 后面接宾语，而短文此处没有宾语，故去掉listened 后面的to。
【小题5】hear sb do sth 听见某人做过某事，hear sb doing sth 听见某人正在做某事，由上下文可知作者下楼来听到有人正在说话，故speak → speaking。
【小题6】房子做主语，谓语动词闯入要用被动语态，又主句是一般过去时，宾语从句用相应的过去完成时，故had后面加been。
【小题7】作表语时frightening 令人害怕的，主语通常是事或物，frightened 感到害怕的，主语通常是人，故frightening → frightened。
【小题8】短文叙述的是过去的事情，应用过去时，且and 前后的时态应一致，故call → called。
【小题9】警察上楼来告诉作者事情的真相，两个动作是并列和递进的而不是表转折，故but→ and。
【小题10】警察上楼来告诉作者事情的真相，所有的东西都很好，故something→ everything。
