Thomas Edison tried two thousand different materials to make the light bulb. When none worked satisfactorily, his assistant　 31　 , “All our work is in vain. We have learned nothing. ”

　 Thomas Edison replied very　 32 , “Oh, we have come a long way and we have 　 33 a lot. We now know that there are two thousand materials which we cannot 34　 to make a good light bulb. ”

　 If we learn from our mistakes, then we are　 35　 . If we learn from someone else’s mistakes, then we are genius. Success is nothing more than a few simple disciplines 　 36　 daily and failure is nothing more than a few small　 37 　 repeated daily.

　 How　 38 the above lines are! Success takes 　 39 . We’ll make mistakes 40 　 we do things in too much of a hurry. When we do not practice disciplines in life, we don’t build enough confidence to 　 41 new and challenging tasks which are important and matter in life. Our confidence　 42 what we think of ourselves and whether we believe in ourselves. We are all born with exceptional　 43　 , but only a few really　 44　 their true potential and make efforts in life and the others just lead a(n)　 45　 life. Do you want to be exceptional?

　 Success is a fruit which everyone wants to 　 46　 but it is not found everywhere and no one can 　 47　 it without serious efforts.

　 Those who want to succeed will find a way; those who don’t will find a(n) 48　 !

　 Success depends upon previous　 49　 , and without it we will end in failure.

　 When you are　 50　 , please enjoy it and give your hand to others who want to accomplish something.

Some years ago I worked with people on public welfare. I believed that everybody had the ability to be 　26 and all we have to do was to make them start working.

The first thing I said to them was, "I would like to know what your 　 27 are." Everyone looked at me as if I were 28 . One woman said "I don't know what you can 　29 with dreams. The rats are eating up my kids." I said. "That's terrible. You are very much 　30 with the rats and your kids. How can we help?" " I could use a new screen door（纱门）because there are 31 in the old." I asked, "Is there anybody knowing 　32 to fix it?" A man said, "Long ago I used to do things like that but now I have a bad back, but I'll 33 ." I gave him some money to do that.

　 The next week, when the group was 34, I asked the woman, "Well, is your 35 door fixed?" "Oh, yes," she said. "Then we can start dreaming, right?" She 36 at me. I asked the man, "How do you feel?" He said, "Well, it's funny that I'm beginning to feel a lot 　37 ." These seemingly small 　38 allowed the group to see that dreams were not stupid. One woman 　39 that she wanted to be a secretary. I said, " What 　40 in your way?" She answered, "I have six kids, and no one can 　41 　them while I'm away." I asked "Who would help this woman while she gets some 　42 at school?" Another woman said "I got kids, too, but I could do that." So the woman went to school.

In 12 weeks these people were 43 public welfare. The woman who 44 the children became a licensed foster care (代别人照看孩子)person. The man became a handyman. I've not only done that 　45 , I've done it many times.

Science seems to be getting closer to answering a very old mystery. Homing pigeons can be 　36　 hundreds of miles from their homes. When they are let to go to 　37　 again, they find their way home. Because of this special ability to 　38　,pigeons have been used 　 39　 messengers for hundreds of years.

Today people even breed homing pigeons for 　40　 at a sport. The birds are shipped to some chosen 　41　 a few hundred miles away. Then all of them are let to go together. The winner is the bird that gets home 　42　.A good race can make it home from 500 miles away 　43　 a single day.

　 The mystery of the homing pigeons is how they 　 44　 directions and how they find home. The first part seems to be pretty well 　 45　,and we know of two ways that pigeons tell directions. First, they use the sun. Experiments show that homing pigeons can tell 　46　 by the sun. What happens when the 　47　 is darkly overcoat by clouds and no one can 　48　 where the sun is? Then the pigeons still find their way home.

　Naturally, people have wondered whether pigeons might have a built-in compass　 49　 that would tell them about the direction of the 　　 50 　 magnetic(磁的)field. Many different kinds of experiments were 　 51　 　.Here’s what the scientists decided 　 52　 they had made experiments many times. When pigeons can see the sun, they use it as their 　 　53　 　 means of direction-finding. When they can’t see the sun, they use some 　54　 way to sense direction from the earth’s magnetic field.

　 But how do pigeons know 　55　 direction is toward home? What do they use that we would call a map? These are other questions to be answered.
