English Idioms

Few days ago, I borrowed a book about useful english idioms from the school library. Becaue I think learn some english idioms can help my writing. This book contains 10 aspects of idiom like "People", "Emotions" , "Business", and etc. I want to share some idioms that I feel interesting or useful in this book for everybody :

☆ In hot water

It is means someone get into trouble.
I think none want into hot water.

☆ In one's shose

This idom denotes be in one's situation.
I just think one thing - it smells bad.

☆ Cut no ice

This idiom means it is no influence in things.
"Ice?", I think it is the idiom about eating at begining.

☆ Find your feet

It is denotes get used to a new situation.
"What? my feet?", this idiom confused me when I saw it first time.
