    答案是 1 -- has played

    Since John's mother came home, he has played the on-line games.

    (分析)

    (1)

    這是現在完成式的用法

    時間起點: John's mother 回家那一刻

    時間截止點: 現在

    (2)

    since是連接詞, 後面接一個過去式時態的子句

    解釋為"自從....."

    主要子句用 have/has 過去分詞

    (3)

    since引導的子句在整個句子中算是副詞子句, 點出時間

    可放前面, 也可放後面

    放前面時, 記得要加逗號 "," 再寫主要子句

    Since John's mother came home, he has played the on-line games.

    John has played the on-line games since his mother came home.

    (4)

    since也可當成介系詞

    如果用介系詞 since, 後面當然要加名詞

    那就可以寫成

    John has played the on-line games since his mother's coming home.

    把動詞 come 加上 ing 變成 coming ( 名詞 )

    在coming 前面加上所有格 his mother's來點出是誰 coming home

    希望這樣解釋夠清楚
