听力原文： When people succeed, it is because of hard work, but luck has a lot to do with it, too. Success without some luck is almost impossible. The French emperor Napoleon said of one of his generals, "I know he's good. But is he lucky？" Napoleon knew that all the hard work and talent in the world can't make up for bad luck. However, hard work can invite good luck..
When it comes to success, luck can mean being in the right place to meet someone, or having the right skills to get a job done. It might mean turning down an offer and then having a better offer come along. Nothing can replace hard work, but working hard also means you're preparing yourself opportunity. Opportunity very often depends on luck.
How many of the great inventions and discoveries came about through a lucky mistake or a lucky chance？ One of the biggest lucky mistakes in history is Columbus' so-called discovery of America. He enriched his sponsors and changed history, but he was really looking for India. However, Columbus' chance discovery wasn't pure luck. It was backed up by years of studying and calculating. He worked hard to prove his theory that the world was round.
People who work hard help make their own luck by being ready opportunity knocks. When it comes to success, hard work and luck are always hand in hand.

A．Hard work is the most important thing for one's success.
B．Hard work may invite good luck.
C．Good luck plays an important role in one's success.
D．Success has nothing to do with luck.

It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. You either have science or you don't, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful hits,
The only solid piece of scientific truth abut which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th. century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.
But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can' t be answered, sooner or later, including even the matter of consciousness. To be sure, there may well be questions we can't think up and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention.
According to the author, really good science ______.
A．would surprise the brightest minds of the 18th century Enlightenment
B．will help people to make the right choice in advance
C．will produce results which cannot be foreseen
D．will bring about disturbing results
