阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Imagine life as a game in which you are playing some five balls in the air. You name them-work, family, health, friends and spirit, and you’re keeping all these balls in the air.

You understand that work is a rubber ball. If you drop it, it will bounce back. But the other four balls are made of glass. If you drop one of these, it will be irrevocably (不可逆转地) scuffed (磨损), marked, damaged or even broken into pieces. They will never be the same. You must understand that and try for balance in your life. How?

Don’t undermine (逐渐损害) your worth by comparing yourself with others. It is because we are different and each of us is special. Don’t set your goals by what other people consider important. Only you know what is the best for you. Don’t take for granted the things closest to your heart. Hold on to them as you would to life, for without them, it’s meaningless. Don’t let life slip through your fingers by living in the past or in the future. By living your life one day at a time, you live all the days of your life. Don’t run through life so fast that you forget not only where you’ve been, but also where you are going. Don’t use time or words carelessly. Life is not a race, but a journey to be enjoyed slowly each step of the way. Yesterday is history, tomorrow is a mystery, and today is a gift. That’s why we call it – the present.

56. What’s the best title of this passage?

A. Today Is A Present    B. How to Live Your Life

C. Life Is A Game         D. Imagine Life as a game

57. What does the underlined sentence mean?

A. not only where you live , but also where you’re going to live

B. all over the world

C. not only what you have done, but what you are going to do as well

D. the places you have been to as well as the places you are going to

A. You should try your best to keep balance in your life.

B. It’s unnecessary to compare yourself with others.

C. Life is just like a race.
