高中英语 非谓语问题the earthquake happening in wenchuan was very seri

你好。出题人犯了一个大错。The earthquake happening in Wenchuan was very serious本身是一个错句。在这里,happening的意思是 that was happening(定语从句部分)。 如果是(was) happening,到底是发生了还是正在发生或者没有发生?所以,正确的表达是：The earthquake that happened in Wenchuan was very serious记住：1 动词的一般式分词ing形式表达的是“正在”,不表达“已经”。 2 having happened这样的结构,一般用来做状语使用,不做定语使用：Having happened quite a few times, such engine failure did cause me much trouble。== As such engine failure had happened quite a few times, it did cause me much trouble。
