英语问题我再写一道题：I was glad and wrote him a letter telling him I would go to congratulate him.
为什么用“telling”，这是个什么结构，详细解释一下，谢谢！
分析：该题I was glad and wrote him a letter telling him I would go to congratulate him.
可以这样看：I was glad and wrote him a letter that(which) tells him I would go to congratulate him.
如果省略that(which)的话,那不符合句子结构了!简单的讲,你可以这样理解telling=that(which) tells ,现在分词做主语! 呵呵,好久没碰语法了!都记得不是很清楚了!
答：不定式做状语通常用于未来将要发生的动作,与前面的wrote(已经发生了的动作)时态不合,所以这里用现在分词短语做目的状语.详情>>
