As I was trying to find my way out, I suddenly heard some noise above me. 地震发生时我正在睡觉。 人们四处奔跑,玻璃和砖块纷纷落下。 正当我试图找到出去的路时,我突然听到上面有声音。 Note:When a shorter action happened at the same time as a longer action, we use the past continuous tense for the longer action and the simple past tense for the shorter action. When there are two long actions,we often use while. 注意:当一个较短的动作与一个较长的动作同时发生时,我们用过去进行时表示较长的动作,用一般过去时表示较短的动作。当有两个长动作时,我们经常使用 while。 If the shorter action is in the main clause, we can use when,while or as to join them. 如果较短的动作在 主句中,我们可以使用 when、 while 或 as 来连接它们。 When/While/As Millie was watching TV Andy came into the room. 当 Millie 看电视的时候 Andy 走进了房间。 If the longer action is in the main clause, we often use when to join them. 如果主句中有较长的动作,我们经常用 When 加入它们。 Millie was watching TV when Andy came into the room. Andy 进屋时 Millie 正在看电视。 We use a comma to separate the two clauses if when,while or as comes at the beginning of the sentence. 如果 when、 while 或 as 出现在句首,我们就用逗号分隔这两个从句。 When the earthquake started,most people were sleeping. 地震发生时,大多数人都在睡觉。 Playing in the snow Some Class 1,Grade 8 students went to play in the snow.
