One morning I wasted nearly an hour watching a tiny ant carry a huge feather. Several times, it   36  several obstacles in its path. And after a brief pause it would make the necessary detour (绕道).   37  one point, the ant had to cross a crack(裂缝) about 10mm wide. After some   38   thoughts, the ant laid the feather over the crack, walked   39  it and picked the feather up on the other side, then continued on its way. I was   40  by the cleverness of this ant. It was only a small insect, lacking in   41  yet equipped with a brain to reason, explore, discover and overcome.   42   this ant, like the other two-legged creatures   43  on the earth, also shares human failings.
After some time the ant   44  reached its destination — a flower bed and a small hole that was the entrance to its   45  home. It was there that the ant met its   46   . How could that large feather possibly   47  such a small hole? Of course, it couldn’t. So the ant, after all this   48  and using great brightness, overcoming problems a1l along the way, just gave up the   49  and went home. The ant had not thought the problem through   50  it began its journey and in the end the feather was   51  more than a burden. Isn’t our   52  like that?
We worry about our families; we worry about the   53  of money; and we worry about all kinds of things. These are all burdens — the things we pick up along life’s path, and drag them around the obstacles and over the cracks that life will bring, only to   54  that at the destination they are   55  and we can’t take them with us.

All too often , a choice that seems sustainable（可持续的）turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol（乙醇）for fuel from corn . Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea .

One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land — including, in some cases, rain forest in places such as Brazil — into farmland, which in turn gives off lots of carbon dioxide（CO₂）into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.

You cannot really declare any practice “sustainable” until you have done a complete lift-cycle analysis of its environmental（环境的）costs. Even then, technology and public policy keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainable requires plenty of thought on an ongoing basis.

“ Are you too stupid to do anything right？”These words—said by a woman to a little boy who was obviously her son—were spoken   21    he had walked away from her．They boy returned, his eyes down-cast.

Not a   22     moment, perhaps,   23     small moments sometimes last a very long time．And a few words—though they mean   24    at the time to the people who say them—can have great   25    .

I recently heard a story from a man named Malcolm Dalkoff．For the last 24 years he has been a professional   26    ．Here is what he told me:

As a boy in Rock Island, Dalkoff was terribly   27    ．He had few   28    and no self-confidence．One day, his English teacher, Ruth Brach, gave the class an assignment（作业）．The students had been reading To Kill a Mockingbird．Now they were to write their own chapter that would   29     the last chapter of the novel.

Dalkoff wrote his chapter and turned it   30   ．Today he can not recall anything   31 

about the chapter he wrote, or what   32    Mrs．Branch gave him．What he does remember is the four words Mrs．Brach wrote in margin（空白处）of the paper：“This is   33   writing.”

    Four words．They   34     his life.

    “   35     I read those words, I had no idea of who I was or   36   I was going to be.”he said.“After reading her note, I went home and wrote a short story, something I had always been   37    of doing but never believed I could do.”

       Over the rest of that year in school, he wrote many short stories and always brought them to school for Mrs．Brach to evaluate．She was   38     , tough and honest.“She was just what I

   39   .”Dalkoff said.

       His confidence   40   ．Dalkoff believes that none of this would have happened if that woman had not written those four words in the margin of his paper.

We had moved from Cairo to Mt. Vernon, Illinois, away from my grandmother when I was eight years old. I missed her  36 . I was told I was her favorite grandchild; she was my favorite granny. Mother must have sensed my  37 , for she would take my little brother and me back to visit my Granny on occasions.

She didn’t live in a big house or have expensive things, but I never  38  it; I just knew she loved me and I loved her back.

We had lived, for a time, next door to her  39  my father was away during World War II.

Granny had never had very much in the way of  40  or material things. But it was the little things she gave me that had always  41 . Things like letting me dip my fingers in the sugar bowl or the coffee she let me drink from her  42_. She allowed me to sit on top of her kitchen table to enjoy those privileges.

She also had a vinegar bottle that sat high on a shelf that was  43 , in my eyes; I asked if I could have it someday. It was given to me in a box after her  44 . She remembered in her last days; love is like that.

She didn’t have much;  45  did we. But she did something for my brother and me. I will always remember she  46  her pennies in a glass jar. I am sure Granny could have used those pennies herself  47  she saved them to give us when we came to  48  her.

I don’t remember how much we  49  on our visits, nor was the  50  important. It was the idea that she remembered us, and cared about us, when we were away from her.

Those  51 , of when I was a child, still give me  52  feelings now. I often wonder, after all those years, when I am lucky enough to find a  53  lying on the ground  54 , if it could possibly be Granny tossing me pennies from  55 .
