  There are many problems connected with space travel.The first and greatest of them is gravity(重力).If you let your pencil drop to the floor, you can see gravity in action.Everything is held to the earth by the force, which can be described by its weight.A rocket must go at least 2500 miles an hour to take anyone beyond the gravity of the earth into space.

  Another problem is the strainthat a person feels when a rocket leaves the ground.Anything that is not moving tends to keep still.As the rocket leaves the ground, it pushes upwards strongly and the person in it is pushed back against the chair.Gravity gives the body a force equal to nine times its normal force.

  Once out of the earth’s gravity, an astronaut is affected by another problem, weightlessness.Here, if a pencil drops, it does not fall.If a glass of water is turned upside down, the water will not fall out.All of us are used to gravity.Recent long flights have shown that the body needs special exercise in a spaceship.

(1)

  What if I had the wrong music? What if I played the wrong notes?

  As it  40 , I was never able to answer these questions because the spotlight was  41 for me. I grasped my hands tightly together, drying off the sweat.

  There was no  48  that I was going to lose my concentration. To keep this promise to myself, I leaned  49 and focused carefully on the music.  50 1 came to the end of the page, a warning  51 inside my head: DON' T MAKE A MISTAKE WHEN YOU TURN THE PAGE!

  Needless to say, I 52  myself with all my heart and mind. And, proud of my "page- turning" feat (技艺), I finished the 53  of the piece without making a single mistake.

After the final note died away, a celebration went into action 54  my head. I had finished. I had mastered the  55 .

In the summer of 1978 an English farmer named Lan Stevens was driving his tractor through a field of wheat    1    he discovered something strange.

    Some of his wheat was lying flat on the ground. The    2    wheat formed a circle about six meters    3   . Around this circle were four smaller circles of flattened wheat. The five circles were in a formation    4    five dots on dice.

    Three years later a farmer who lived nearby discovered similar circles in one of his fields. These circles were    5    —nearly 15 meters across.

    That same year, yet another English farmer discovered three circles of flattened wheat on his land—one large circle    6    two small circles.

    During the    7    years, farmers in England found the mysterious circles in their fields more and more often. In 1987 they discovered 50 circles; in 1988, 98 circles; and in 1989, 270 circles.

    The circles are called “crop circles” because they appear in fields of grain—usually wheat or corn.

    The grain in the circles lies flat    8    but is never broken: it continues to grow horizontal, and farmers can later    9    it.

    Many people believe that beings from outer space are making the circles. Some think that the beings are trying to communicate    10    us from far away and that the crop circles are messages from them.

       11    believe that the beings have actually landed on earth and that the circles are  12 left by their spaceships. Several times people reported    13    strange flying objects near fields where crop circles later appeared.

    Scientists who have studied the crop circles say they're not sure what    14    them. They 15    several theories.

    For example, some scientists say that “microburst” of wind create the circles. A microburst is a    16    rush of cool air—the same downward rush of air that sometimes causes an airplane to crash.

    Other scientists say that forces    17    the earth cause the circles to appear.

    Experts from    18    have studied them. What do the experts    19    the crop circles? They say what Lan Stevens said: “They don't know how    20    these things.”
