1. passes 2. alive 3. staring 4. didn't notice 5. coaches

1. 句中"on weekdays"表明是习惯性动作，用一般现在时，主语"My father"是第三人称单数，故填passes。
2. "is"后接形容词作表语，"live"的形容词形式为alive，意为“活着的”，故填alive。
3. "be busy doing sth."是固定搭配，意为“忙于做某事”，故填staring。
4. 由"was reading"可知时态为过去进行时，and连接并列谓语，“没注意”用过去式否定，故填didn't notice。
5. "two"后接可数名词复数，"coach"的复数形式为coaches，故填coaches。
