阅读下列材料，回答问题.

材料一 比如海湾战争，全世界都知道7月15日将会开战，但哪一小时打，前半夜还是后半夜打，谁都不知道。……又如美国偷袭利比亚，只花了18分钟……从直接损失上看，多国部队42天花了610亿美元，伊方则损失了1900亿美元，科威特损失了1600亿美元。……二战时，用B-17飞机，需出动4500架次，投弹9000枚方能摧毁一个目标，到了越战期间，用F-105飞机，需出动95架次，投弹190枚，方能摧毁一个目标，而在海湾战争中，用一架F-117飞机投下一枚炸弹，就能准确地命中目标……在科索沃战争中，北约使用的精确制导武器的数量占总投弹量的90%，轰炸了南联盟40多座城市，而造成人员的死亡总共不到2000人。与此形成鲜明对照的是，这与二战期间相同天数中人员平均伤亡100万人相比，是天壤之别。

——王增铨《现代高技术局部战争》

材料二 当坦克出现以后，又发展成了机动作战。到了高技术战争中，由于一大批高、新技术群在战争中的广泛运用，出现了各种各样的作战方式，比如，导弹袭击式的“精确战”；外科手术式的“点穴战”；破坏结构式的“瘫痪战”；非致命式的“软杀战”；指挥控制式的“信息战”；陆、海、空、天、电一体的“全维战”，此外，还有“环境战”“太空战”“心理战”等等。……海湾战争中……伊拉克拥有120万军队，号称是世界上第四大军事强国，但他的军兵种比例很不协调，120万人中，陆军占了115万人，占他总兵力的96.5%，而空军兵力只有4万，占3%，海军更少，只有5000人，只占0.4%。……1991年的海湾战争，负责战场指挥的7名美国高级指挥官中，有6人具有硕士以上学位，成功地实施了战略协同和作战指挥，被称为“硕士导演的战争”……目前，美国军官全部为大学本科以上学历，其中硕士、博士占38.4%。俄罗斯军官98%以上受过高等教育，日本军官全部具有大学以上文化程度，印度也要求营以上军官必须获得硕士学位。

       1   . If you give and give without making time to fill your own needs, then it's likely you will burn out,

or feel upset. When you take and take without giving back, you never feel fulfilled, so you are always

searching for ways to fill the void in your life.

     The way to create a healthy balance between giving and receiving is to know and then live by your values.

I break values up into two groups which I call being and having values.    2    I suggest to my clients that they

choose three being values that are willing to make a commitment to live by. An example of some being values

are:kind, loving, generous, inspirational, peaceful, wise and even powerful. By acting on these values you give

to others through your actions and you inspire others by being a positive role model. Mastering being these

character traits becomes your life purpose. 

       3   . These could be companionship, achievement, and support, being valued or financial security. This is

what yu receive. You take responsibility for filling your own needs by taking steps to create these feelings and

conditions in your life.

     When you make a commitment to live by your being values, it becomes easier to make conscious choices

rather than reactionary ones. If your usual pattern is to talk about your problems, you could choose to think

and act like a calm person.    4   . If your usual pattern is to worry, you could choose to act like a responsible

or wise person. In other words, you would act like the person you choose to be-this is the key to personal

power.

     When you choose to act on your values, you not only feel good about yourself, you reinforce your chosen

beliefs.    5   .

A. Young people have a different set of values.

B. You feel that you have a responsibility to help them.

C. Your having values are the feelings you need to create in order to be happy.

D. Your being values are the character traits (特征,特点) of the ideal person you would like to be.

E. You feel happiest when you create a healthy balance between giving and receiving.

F. A calm person might go for a walk, meditate, or set a time limit before responding.

G. Over time acting in this way changes how you see the world, and in turn the way other people

    think of you.
