When the teacher came in, we were talking. 當(dāng)此句改變主從句的位置時，則為： While we were talking, the teacher came in. b They were singing while we were dancing. 練習(xí)題一、英漢互譯。 1. 在什么時間_ 2. 在圖書館_ 3. 在公交車站_ 4. wait for the bus. _ 5.pick up_6. walk home_ 7. 鬧鐘響_ 8.接電話_ 9. 忙于做某事_ 10. 雨下得很大_ 二、單項選擇。 1. _ I got back, I found my mother cooking for me.
