Language is colourful. There are many    with heart. One of them is to “lose your heart” to someone. When that  , you have fallen in love.     if the person who “won your heart” does not love you, you are   to have a “broken heart.” In your    , you think that the person you loved is “hard-hearted,” and in fact, has a “heart of stone.”
You may decide to “pour out your heart” to a friend. Telling someone about your personal      can often make you feel better.
If your friend does not     to understand how painful your broken heart is, you may ask her to “have a heart.” You are asking your friend to show some sympathy (同情) for your    . Your friend “has her heart in the right place” if she says she is sorry for    you feel.
If your friend says, “My heart bleeds for you”, she means the     . She is a cold-hearted person who does not really      your situation.
When you are feeling    , “your heart is in your mouth.” You might say, for example, that your heart was in your mouth when you asked a bank to lend you some money to      a new house.
If that bank says    to you, do not “lose heart.” Be “strong-hearted.” Sit down with the banker and have a “heart to heart” talk. Be open and honest about your situation. The bank may have a “change of heart” and agree to lend you the money. Then you could    worrying and “put your heart at rest.”
