     阅读下面短文并回答问题,然后将答案写到答题卡相应的位置上(请注意问题后的要求)。

          Anger and bitterness may affect your health. According to a research,forgiveness may help

you keep healthy,both physically and mentally.

     Forgiveness-giving up anger toward another- can greatly reduce your body's anger and

stress responses,which affect your mental and physical health. Research conducted by the University

of Michigan's institute for Social Research has showed that people who for-give themselves and

others experience reduced feelings of restlessness,nervousness and hopelessness. Other researches

have found forgiveness can also lower blood pressure and heart rates.

     "Stress worsens pain,tightens muscles and influences the smooth running of the immune(免疫)

system." says Fred Luskin,director of the Forgiveness Project at Stanford University." People think

they have unlimited storage of anger that will never do harm to their health,but they are quite wrong."

     And good news:You don't have to be Gandhi to forgive others or ask for forgiveness." Forgiveness

is a teachable skill,which you can learn just like you learn to play the piano." says Luskin.

     Remember these tips when learning to forgive:

     Commit yourself. Do whatever you have to do to feel better. Forgiveness is for you not______.

     Grasp the truth. Recognize that your primary bitterness comes from the hurt feelings and physical

upset you suffer now,not what offended or hurt you 2 minutes or 10 years ago.

     Meet positive goals. Instead of mentally replaying your hurt,seek a new and positive future.

     Live well. remember that a life well lived is the most important. Stop focusing on wounded

feelings-that gives the person who caused your pain power over you. Instead,look for love,beauty

and kindness around you.
