     If something happens that makes you feel angry, try these things to help prevent angry feelings from

building up inside.

     1)Exercise. Go for a walk, work out, or go to play a sport. Lots of research has shown that exercise

is a great way to improve your mood and decrease negative feelings.

     2)Write down your thoughts and emotions. You can write things in lots of ways,for example, in a

journal or as your own poetry or song lyrics(歌词). After you'  ve written it down,you can keep it or

throw it away-it doesn'  t matter. The important thing is,writing down your thoughts and feelings can

improve how you feel.When you notice, label, and release feelings as they show up in smaller portions,

they don'  t have a chance to build up inside.

     3)Think deeply or practice deep breathing.T his method is the best one among all the tips if you do

it regularly, as it'  s more of an overall stress management technique that can help you use selfcontrol

when you'  re mad. If you do this regularly, you'  ll find that anger is less likely to build up.

     4)Talk about your feelings with someone you trust. Lots of times there are other emotions, such as

fear or sadness, beneath anger. Talking about them can help.

     These ideas can be helpful for two reasons:

     1)They help you cool down when you feel like your anger might explode. When you need to cool

down, do one or more of the activities in the list above. Think of these as alternatives(可选择的办法)

to taking an action you'  ll regret, such as shouting at someone.Some of them, like writing down

feelings,can help you release tension and begin the thinking process at the same time.

     2)They help you manage anger in general. What if there'  s no immediate problem to solve-you

simply need to shift into a better mood? Sometimes when you'  re angry, and you have no better way

to manage anger although you have tried your best,y ou just need to stop dwelling on how mad you are.
