2004年7月德俄两国化学家共同宣布,在高压下氮气会聚合生成高聚氮,这种高聚氮的    晶体中每个氮原子都通过三个单键与其它氮原子结合并向空间发展构成立体网状结构。已知晶体中N-N键的键能为160 kJ·mol-1,而N≡N的键能为942 kJ·mol-1(键能表示形成化学键释放的能量或者破坏化学键消耗的能量)。则下列有关说法不正确的是

A:键能越大说明化学键越牢固,所构成物质越稳定

B:高聚氮晶体属于原子晶体

C:高聚氮晶体中n(N)∶n(N-N)=1∶3

D:用作炸药或高能材料可能是高聚氮潜在的应用

    To forgive is a virtue, but no one has ever said it is easy. When someone has deeply hurt you, it can be extremely difficult to let go of your hate. However, forgiveness is possible, and it can be surprisingly beneficial to your physical and mental health. People who forgive show less sadness, anger and stress and more hopefulness, according to a recent research.

    ____Try the following steps:

    Calm yourself. ____You can take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, or someone you love. Don't wait for an apology. Many times the person who hurt you does not intend to apologize. They may have wanted to hurt you or they just don't see things the same way. ____ Keep in mind that forgiveness does not necessarily mean becoming friends again with the person who upset you.

    Take the control away from your offender(冒犯者). Rethinking about your hurt gives power to the person who causes you pain. Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around you.

    ____ If you understand your offender, you may realize that he or she was acting out of unawareness, fear, and even love. You may want to write a letter to yourself from your offender's point of view.

    Don't forget to forgive yourself. ____ But it can rob you of your self-confidence if you don't do it.

A. Why should you forgive?

B. How should you start to forgive?

C. Recognize the benefits of forgiveness.

D. Try to see things from your offender's angle.

E. For some people, forgiving themselves is the biggest challenge.

F. To make your anger die away, try a simple stress-management technique.

G. If you wait for people to apologize, you could be waiting an awfully long time.
