When I was a child, after bedtime I would often  (3)  my bed in my sleeping clothes, go to the  (4)  and stare at the stars. I had so many questions. How far away were those tiny points of light? Didspace go on_  (5)  and ever, or was there some end to space, some giant edge? And if so, what  (6)  beyond the edge?

  (7)  of my childhood questions: Did  (8)  go on forever? I looked at pictures of my parents and grandparents and tried to  (9)  their parents, and so on, back through the generations, back and back through time. Looking out of my bedroom window  (10)  _the endlessness of space, time seemed to spread forward and backward  (11)  , swallowing me, swallowing my parents and great-grandparents, the whole  (12)  of earth. Does time go on forever? Or is there some  (13)  of time? And if so, what came before?

When I  (14)  , I became a professional astrophysicist.  (15)  I never answered any of these questions, they continued to  (16)  me, to affect me, to drive me in my scientific research, to cause me to live on just fish and no sleep for  (17)  at a time while I was  (18)  a science problem. These  (19)  questions, and questions like them, challenge and never leave the leading__  (20)  of today.

Job stress has been known to cause heart problems in people who already have cardiovascular(心血管) disease. Now Finnish scientists have shown that the pressure of work can __  (1)  _cause damage in healthy people.

   High blood pressure, lack of __  (2)  _, smoking and being overweight __  (3)  __ to heart disease -- a __  (4)  __ killer in many industrialized countries.

But Mika Kivimaki, of the Finnish Institute of Occupational Health, and his colleagues, who studied the __  (5)  __ histories of 812 healthy Finnish men and women in a metal industry company over 25 years, said job stress also plays an important role.

   Workers who had the highest job-related stress levels at the start of the study were more than twice as __  (6)  __ to die of heart disease, __  (7)  __ the study published in The British Medical Journal.

   Work stress __  (8)  __ too much work as well as a lack of satisfaction and feeling undervalued and __  (9)  .

   Many people work long hours, but if the effort is __  (10)  __, the stress is minimized. Kivimaki said job pressure is damaging when being overworked is __  (11)  __ with little or no control, unfair supervision and few career opportunities.

The British Heart Foundation said the results __  (12)  __ earlier research showing that people in jobs with low control, such as manual workers, could be at greater __(13)__ of heart disease than other employees.

   "It is __  (13)  __ for people to try to minimize levels of stress at work and for employers to __(15)__ people to have more control at work and to be rewarded for their success," the foundation said in a statement.

Sometimes people come into your life and they were meant to be there to serve some sort of propose, to teach you a lesson, or help you   (1)   out who you are or who you want to become. You never know who these people   (2)   be, but when you lock eyes with them, you know   (3)    that they will affect your life in some profound way.

   And sometimes things happen to you that may seem horrible,    (4)  , and unfair at first, but   (5)  you find that without overcoming those obstacles you would have never realized your potential, strength, will, or heart. Everything happens   (6)   . Nothing happens by chance or by means of good or bad luck.Ⅲness, injury, lost moments of true greatness, and pure stupidity all occur to test the    (7)   of your soul. Without these small tests,    (8)   they may be, life would be like a smooth, straight road to    (9)   . It would be safe and comfortable, but dull and entirely   (10)    .

   The people you meet who   (11)   your life, and the success and downfalls you experience, help to create who you are and who you become.   (12)   the bad experiences can be learnt from. In fact they are probably the most important    (13)   . If someone hurts you or breaks your heart,   (14)   them, for they have helped you learn about trust and the importance of being careful    (15)   you open your heart. If someone loves you, love them back,    (16)   because they love you, but because    (17)   , they are teaching you to love and how to open your heart and eyes to things. Make every day   (18)   . Appreciate every moment and   (19)   from those moments everything that you possibly can, for you may never be able to experience it again. Tell yourself you are   (20)   and believe in yourself, for if you don't believe in yourself, it will be hard for others to believe in you.

Most times we see impossibility in the light of impossibility. But let’s get this important _(1)_ clearly: in every impossibility, there is a (n) __(2)__. Even the word, “IMPOSSIBLE” says “I’M POSSIBLE.”

 Robert X. Perez said, “The seeds of the success spring from failure’s ashes.” Failure is not the __(11)__ , it is a pointer (教鞭), which makes you do better than what you did. You have to know that you are in a __(12)__ study of life. What you face is for your training.
