    will go/are going
    (go) to find their new owners soon.
    答案：1. have cleared
    解析："already"是现在完成时的标志，主语"we"，所以填"have cleared"。
    2. for
    解析："for a long time"是固定搭配，意为“很长时间”。
    3. have had
    解析："since I was a baby"是现在完成时的标志，"have"的过去分词是"had"，填"have had"。
    4. hasn't played
    解析："for three years ago"表述错误，应为"since three years ago"，是现在完成时的标志，否定形式用"hasn't played"。
    5. since
    解析：“自从三年前他就没玩过它们了”，用"since"。
    6. has been
    解析："for years"是时间段，现在完成时，主语"it"，填"has been"。
    7. have kept
    解析："for many years"是现在完成时的标志，主语"they"，填"have kept"。
    8. will go/are going
    解析："soon"表示将来，用一般将来时"will go"或现在进行时表将来"are going"。
