老师说，only to do sth 是一个比较特殊的不定式结构，只用于表示一种意料之外的结果。如：
He hurried to the house only to find that it was empty. 他急忙赶到那所房屋，却发现空无一人。
He returned after the war, only to be told that his wife had left him. 他战后回来，人家诉他他老婆已离开他了。
He lifted a rock only to drop it on his own feet. 他搬起石头砸了我们的脚。
请问：假如要表示“只不过为了做某事”呢？难道就不可用 only to do sth 来表示吗？如要表示“他如此做只不过为了讨好她”，可以如此翻译吗？
He does so only to please her.
请专家老师指点，谢谢！
“他如此做只不过为了讨好她”可以翻译为：He does so only to please her.（表目的）
▲only to do既可表“意料之外的结果”，也可表“某种特殊的目的”。到底是表示“结果”还是“目的”，应该依据具体的语境来判断。如：
He lifted a rock only to drop it on his own feet. 他搬起石头砸了我们的脚。（表结果）
▲请看摘自《柯林斯高级英语学习词典》上两个表“目的”的例句：
They are there only to satisfy their ghoulish curiosity. 他们去那里纯粹是为了满足其病态的好奇心。
I didnt mean to hurt her, only to keep her still. 我不是故意要弄痛她，只不过想让她别乱动。
