    這句動詞要用要加ing,變成mopping的最主要理由,是因英文慣用的語法之一:在進行式 (現在、過去、未來等不同時間點,正在發生的動作)時,都要如此。例:

    He is mopping the floor now.

    (現在進行式) (他現在正在拖地)

    He was mopping the floor then.

    (過去進行式) (他那時正在拖地) (即版大原句)

    He will be mopping the floor around nine o’clock tomorrow morning.

    (未來進行式) (他在明早九點會正在拖地)

    其它動詞也要如此變化的狀況,還有: 1. 介系詞後面的動名詞:

    He spent all day (on) mopping the deck, peeling potatoes, and washing the sailor’s smelly socks.

    He has difficulty (in) mopping the floor because his back has been seriously injured.

    2. 簡化分詞

    He came running.

    (他跑著來) (兩個動詞同時發生或間隔時間很短)

    Hearing the bad news, he rushed out of the house.

    (聽到壞消息之後,他從房子衝出)

    = After he heard the bad news, he rushed out of the house.

    (主詞是同一人,可去掉其中一個主詞和連接詞after,再把動詞heard加ing)

    3. 當做主詞或受詞用 (即動名詞)

    Taking regular exercise is good for our health. (做規律的運動有益健康) (當主詞用)

    Susan likes shopping, dancing, and singing. (她愛血拼、跳舞等) (當受詞用)

    4. 當做形容詞用 (即現在分詞)

    His exciting jokes make all the audiences laugh out loud.

    (令人興奮的笑話)

    There is no way for us to drink boiling water.

    (正在沸騰的水)

    was是be動詞

    mop是動詞

    因為英文文法中一個單句不能有兩個動詞

    所以要加ing讓mop變成動名詞
