You're " getting your feet wet, " and then when you are ready, you'll get the rest of your body wet – then perhaps you will jump in with both feet.

你正在“弄湿你的脚” ，然后当你准备好时，你会弄湿你身体的其余部分——然后你可能会双脚跳进去。

The expression " to get your feet wet" is somewhat of the opposite of " to jump in with both feet." " To get your feet wet" means to move slowly without risking too much.

“把你的脚弄湿” 这个表达方式与“用双脚跳进去” 有点相反。 “把你的脚弄湿” 的意思是慢慢移动， 不要冒太大的风险。
