听力原文： The sum total of our knowledge is very small compared to the size of our ignorance. Every advance on the frontier of knowledge opens up a great vista of the unknown. The scientist is not happy except when he finds something new. Science is an incomplete task just as life is incomplete. He can only be happy because he has the opportunity to continue the search. Fulfillment can never be there so long as knowledge is imperfect.
The search for truth is not a peaceful occupation. The happiest people I have known have not been the men of great worldly achievements or wealth. They have been the simple people who are happily married, enjoying good health and good family life.
I do not think we search for the stars or moon because we make up our minds to do so, but because we can't help ourselves. Imagination is not an attribute of happiness. A person can be very happy when he knows nothing.
While it is true you can get happiness peace and serenity from being at the lower end of the ladder, it is also true that you cannot enjoy the ecstasy of achievement. Success in the general sense of the term means the opportunity to experience and to realize to the maximum the forces that are within us.
In the author's opinion, why do we search the stars or moon？
听力原文： Not long ago it was assumed that the dangers man would meet in space would be terrible, the main ones being radiation and the danger of being hit by meteors. It is perhaps worth remembering that less than two centuries ago the dangers of train travel seemed similarly terrible. A man would certainly die, it was thought, if carried along at a speed of thirty kilometers per hour.
There are two sorts of radiation man must fear in space. The first is radiation from the sun, and this is particularly dangerous when the sun is very active and explosions are occurring on its surface. The second, less harmful form. comes from the so-called Van Allen Belts. These are two areas of radiation about 1,500 miles away from the earth. Neither of these forms of radiation area danger to us on the earth, since we are protected by our atmosphere. Specifically, it is that part of our atmosphere known as the ozonosphere which protects ns. This is a belt of the chemical ozone between 12 and 21 miles from the ground, which absorbs all the radiation.
Once outside the atmosphere, however, man is no longer protected, and radiation can be harmful in a number of ways. A distinction must be drawn between the short-and long-term effects of radiation. The former are merely unpleasant, but just because an astronaut returning from a journey in space does not seem to have been greatly harmed, we cannot assume that he is safe. The long-term effects can be extremely serious, even leading to death.
How many kinds of radiation are feared by astronauts？
甲、乙二人同在山坡上放羊，乙的羊混入甲的羊群，甲不知，赶羊回家人圈。甲的行为属于不当得利。()
Surely we ought to hold fast to life, for it is wondrous, and full of a beauty that breaks through every pore of God's own earth. We know that this is so, but all too often we recognize this truth only in our backward glance when we remember what was and then suddenly realize that it is no more.
We remember a beauty that faded, a love that waned. But we remember with far greater pain that we did not see that beauty when it flowered, that we failed to respond with love when it was tendered.
A recent experience re-taught me this truth. I was hospitalized following a severe heart attack and had been in intensive care for several days. It was not a pleasant place.
One morning, I had to have some additional tests. The required machines were located in a building at the opposite end of the hospital, so I had to be wheeled across the courtyard on a gurney.
As we emerged from our unit, the sunlight hit me. That's all there was to my experience. Just the light of the sun. And yet how beautiful it was—how warming, how sparkling, how brilliant!
I looked to see whether anyone else relished the sun's golden glow, but everyone was hurrying to and fro, most with eyes fixed on the ground. Then I remembered how often I, too, had been indifferent to the grandeur of each day, too preoccupied with petty and sometimes even mean concerns to respond to the splendor of it all.
The insight gleaned from that experience is really as commonplace as was the experience itself: life's gifts are precious—but we are too heedless of them.
Hem then is the first pole of life's paradoxical demands on us: Never too busy for the wonder and the awe of life. Be reverent before each dawning day. Embrace each hour. Seize each golden minute.
Hold fast to life... "but not so fast that you cannot let go." This is the second side of life's coin, the opposite pole of its paradox we must accept our losses, and learn how to let go. This is not an easy lesson to learn, especially when we are young and think that the world is ours to command, that whatever we desire with the fun force of our passionate being can, nay, will, be ours. But then life moves along to confront us with realities, and slowly but surely this second troth dawns upon us.
At every stage of life we sustain losses and grow in the process. We begin our independent lives only when we emerge from the womb and lose its protective shelter. We enter a progression of schools, then we leave our mothers and fathers and our childhood homes. We get married and have children and then have to let them go. We confront the death of our parents and our spouses. We face the gradual or not so gradual waning of our own strength. And ultimately, as the parable of the open and closed hand suggests, we must confront the inevitability of our own demise, losing ourselves as it were, all that we were or dreamed to he.
But why should we be reconciled to life's contradictory demands？ Why fashion of beauty when beauty is evanescent？ Why give our heart in love when those we love will ultimately be tom from our grasp？
In order to resolve this paradox, we must seek a wider perspective, viewing our lives as through windows that open on eternity. Once we do that, we realize that though our lives are finite, our deeds on earth weave a timeless pattern.
Life is never just being. It is becoming a relentless flowing on. Our parents live on through us, and we will live on through our children. The institutions we build endure, and we will endure through them. The beauty we fashion cannot be dimmed by death.
