【往期回顾】 接下来,我们就来看看第117课的“每课一句”。 一、课文原文Lesson 117 Tommy’s breakfast When my husband was going into the dining room this morning, he dropped some coins on the floor. There were coins everywhere. We looked for them, but we could not find them all. While we were having breakfast, our little boy, Tommy, found two small coins on the floor. He put them both into his mouth. We both tried to get the coins, but it was too late. Tommy had already swallowed them! Later that morning, when I was doing the housework, my husband telephoned me from the office. “How’s Tommy?” he asked. “I don’t know,” I answered, “Tommy’s been to the toilet three times this morning, but I haven’t had any change yet!” ——选自《新概念英语》第一册,外语教学与研究出版社,1997年10月第1版 二、每课一句When my husband was going into the dining room this morning, he dropped some coins on the floor.本课侧重学习的是过去进行时的用法。 (一)构成方式
