阅读理解。 Years ago, when I started looking for my first job, a wise man advised, "Barbara, be enthusiastic! Enthusiasm will take you further than any amount of experience." How right they were! "Nothing great was ever achieved without enthusiasm." wrote Ralph Waldo Emerson. It is the paste that helps you hang on there when the going tough. It is the inner voice that whispers, "I can do it!" when others shout, "No, you can't!" It took years and years for the early work of Barara McClintock, a geneticist who won the 1983 Nobel Prize in medicine,to be generally accepted. Yet she didn't stop working on her experiments. Work was such a deep pleasure for her that she never thought of stopping. We are all born with wide-eyed, enthusiastic wonder and it is this childlike wonder that gives enthusiastic people such youthful air, whatever their age was. At 90, cellist Palblo Cassls would start his day by playing Bach. As the music flowed through his fingershis stooped shoulders would strengthen and joy would reappear in his eyes. As author and poet Samuei Ulman once wrote, "Years wrinkle (使起皱纹) the skin,but to give up enthusiasmwrinkles the soul." Enthusiastic people also love what they do, regardless of money or power. Patricia Mellrath, retired director of the Missouri Repertory Theatre in Kansas City, was once askedwhere she got her enthusiasm. She replied, "My father, a lawyer long ago told me, I never made a dime until I stopped working for money." If we cannot do what we love as a full-time career, we can as a hobby. Elizabeth Laytonwas 68 before she began to draw. This activity ended periods of depression that had troubled her for at least 30 years,and the quality of her led one critic (批评家)to say, "I'd liketo call Layton a genius." We can't afford to waste tears on "might-have-been". We need to turn the tears into sweat as we go after "what-can-be". We need to live each moment whole-heartedly, which all our senses-including pleasure in the sweet smell of a back-yard garden, the picture of a six-year-old, the beauty of a rainbow.
