Question

英语大神进来看！

He had two adoring sisters who used to follow him around the cillage, much to his annoyance but to the delight of his friends as the girls grew into beautiful teenagers.
much to...这是什么用法啊？
谢谢

Answer 1

much /to his annoyance/ but /to the delight of his friends

much to看到我上面给断的没？much to 不是一个短语，就是一个普通的句子结构，much用来修饰形容annoyance，他的烦恼。他的烦恼和他朋友们的高兴是平衡结构，对等的。
整句翻译是：
他有两个可爱的妹妹，这两个妹妹曾经经常跟在他屁股后面转悠。这对于他更多的是烦恼，但对于他的朋友们却更多的是高兴，特别是随着这两个妹妹长成了漂亮妹子。

追问

明白啦！那为什么这里用“to“呢？

Answer 2

这里much和to并不是词组的，much是形容词，to表示针对的对象，后面那句much to his annoyance but to the delight of his friends as the girls grew into beautiful teenagers意思为：他两妹妹逐渐长大的情况的出现使得他很苦恼，但对他的朋友来说却是件好事。

Answer 3

much to his annoyance 其实就是 to his annoyance/ surprise/ delightment 这种用法很常见吧~加个much强调程度~
