One day, Confucius (孔子) led his students to the State of Chu. When crossing through a
large forest, they saw an old man {#blank#}1{#/blank#} (stand) under a tree, catching
cicadas (蝉) with a bamboo stick. Confucius said, "You
are very good at {#blank#}2{#/blank#} (catch) cicadas. You must have some special skills."
"That's right!" the old man
answered. "The cicadas are clever little insects. If they hear the noise
of the leaves in the wind, they {#blank#}3{#/blank#} (fly) away. Therefore, people who
want to catch cicadas {#blank#}4{#/blank#} (train) their hands to hold a bamboo stick
without shaking. If you can place three pellets (弹珠) on
top of the bamboo stick without falling off, you might be able to catch
cicadas; when five pellets {#blank#}5{#/blank#} (place) on top without falling off,
catching cicadas is as easy as {#blank#}6{#/blank#} (pick) a ball up from the ground."
He then added, "But that is not enough.
People must be good at hiding themselves. Right now, I {#blank#}7{#/blank#} (stand) under
a tree like half of a tree stump (树桩). Last of all, one
must be attentive(专心的). When I am catching cicadas, I only
see their wings. No matter what {#blank#}8{#/blank#} (happen), nothing will disturb
me."
Hearing this, Confucius {#blank#}9{#/blank#} (turn)
to his students and said, "No matter what you do, you can only succeed if
you love what you're doing and pay enough attention to it. This is what this
old man {#blank#}10{#/blank#} (teach) us."
