用touch wood表达“但愿走好运”

英国人有时也迷信，比如 touch wood 就是但愿走好运的意思。

• I‘ve done all of the preparation for the exam, so nothing can go wrong now – touch wood!
• I‘ve never broken any bones, touch wood!
• The train is currently on time so we shouldn’t miss our flight, touch wood.

值得注意的是，短语 touch-and-go 通常用来形容某种形式或某人的状态很不稳定。

• My grandfather had an operation last week. It was touch-and-go at one point, but he‘s fully recovered now.
