阅读理解

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项多余选项。

        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 you 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.
