They were singing while we were dancing.不說(shuō)They were singing when we were dancing.when和while 還可作并列連詞。when表示“在那時(shí)”；while表示“而，卻”，表對(duì)照關(guān)系。如： 1. The girl was running across the road when a motor bike knocked her down. 那女孩正要跑過(guò)馬路，這時(shí)一輛摩托車把她撞倒。 2. He is tall while his father is short. 他長(zhǎng)得很高，而他爸爸卻很矮。 練一練：用when和while填空1._ the boy was walking to school, he saw a bird in a tree.2._I left the classroom, the students were cleaning the blackboard. 3.
