[1] Hurt may occur at any time in our daily life, and forgiving someone who has hurt you or let you down is never an easy thing．Several new studies, however, say that  it could have a lot of health benefits．When you think of forgiveness, you probably don’t think of it as being a health or medical problem．Studies from Stanford University, on the other hand, show that something like anger can ________.

[2] When cartoon book characters like the Incredible Hulk get angry, they change colors and often gain special power．In the real world, anger is less obvious and may be more dangerous. That’s why Professor Fred Luskin, founder of the Stanford Forgiveness for Good, says being angry can harm your physical and mental health. Two new studies seem to show the same idea.

[3] The studies find that people who are able to forgive feel less stress, less back pain, and less depression. They also have fewer headache, lower blood pressure, and fewer problems on sleeping.

[4] So it doesn’t matter if your anger is caused by the traffic or other things．Learning to let it go is important. Techniques such as deep breath or thought can help. Or just ask yourself if it’s worth hurting yourself by staying angry with someone else.

[5] Forgiveness does not mean that you simply accept what happened and say it’s OK. Instead, it’s a way of making peace with yourself about what happened in the past.

下列各项关于资产减值的说法中，不正确的是()。

A.以前报告期间的计算结果表明，资产可收回金额远高于其账面价值，之后又没有发生消除这一差异的交易或事项，企业在资产负债表日可以不需要重新估计该资产的可收回金额

B.资产的公允价值减去处置费用后的净额与资产预计未来现金流量的现值，必须都超过资产的账面价值，才表明资产没有发生减值

C.资产的公允价值减去处置费用后的净额如果无法估计的，应当以该资产预计未来现金流量的现值作为其可收回金额

D.以前报告期间的计算与分析表明，资产可收回金额对于资产减值准则中所列示的一种或多种减值迹象不敏感，在本报告期间又发生了这些减值迹象的，在资产负债表日企业可以不需因为上述减值迹象的出现而重新估计该资产的可收回金额
