用所给单词的适当形式填空

1.has been reparing;has repaired 解析：第一个空：这个人从7点到10点一直在修你的自行车 应用现在完成进行时，has been doing；第二个空：他现在已经修好它了 already说明应用现在完成时，has done
2.was working 解析：你昨天晚上为什么不来这个聚会？---我那时正在工厂上班 ，表示过去进行时，由then可以看出
3.are doing;am playing 解析：由now可知，要用现在进行时

希望帮到你，祝学习进步

just是完成时的时态标志，所以本句肯定是用现在完成时，现在完成时由has/have＋动词过去分词构成，所以本句应填has
returned
。
因为本句主语是He，所以要用
has。
