【題目】B

How to improve my life? Many people think that they have to accept whatever life throws at them. Theyll say, This is my fate, my destiny. I cannot change it.

Of course not! You dont have to suffer needlessly. Your destiny depends on you, not on any other outer factors. I know someone who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is? She wakes up in the morning, goes to work, comes back home, relaxes, chats with people, watches TV, then goes to sleep. Next day, the same things cycle follow.

Huh! Is this what she calls doing her best? She believes she has tried her best and just accepts it in her heart that this is the life that God has intended for her to live; that her luck can only change if God wills it. Of course God wants us to be happy and live our life to the fullest, but we have to do our share of exerting (運用) the effort to live the life of our dreams.

Remember that you reap what you sow. You just dont sit around and wait for a million dollars to fall from the sky. You have to get off the couch, get your eyes off the TV screen, get your hands off the phone. Dont expect your luck to change unless you do something about it. If something goes wrong, dont just regard it as a temporary(臨時的) setback; but use it as feedback. Learn your lesson, make the most of the situation, and do something to solve the problem. Its not enough to think positively; you also have to act positively.

If someones life is in the trouble, do you just hope and pray that things will turn out fine? Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, dont just stand (or sit) there, do something to improve your life.

【1】According to the woman mentioned in the passage, her life _______.

A. doesnt need improving B. couldnt be improved

C. will be better some day D. will be worse in the future

【2】What does the author think of the womans life?

A. Positive. B. Satisfying. C. Colorful. D. Passive.

【3】Which of the following statements is the authors opinion?

A. Your temporary problem is not discouraging.

B. Your luck can be changed by your hard work.

C. You can only achieve success when God wills it.

D. You should treat yourself in the way you treat friends.

【4】 In Para.5, the author emphasized the importance of _______.

A. positive action B. positive thinking

C. hope for the best D. intention to succeed

【5】The text is mainly written to advise you to _________.
