For thousands of years, people have told fables (寓言) _ 41 _ (teach) a lesson or to pass on wisdom. Fables were part
of the oral tradition of many early cultures, and the well-known Aesop’s fables date to the _ 42 _ (six) century, B.
C. Yet, the form of the fable still has values today, _ 43 _ Rachel Carson says in “A Fable for Tomorrow”
Carson uses a simple, direct style common to fable. In fact, her style and tone (口吻) are seemingly directed at
children. “There was once a town in the heart of America, _ 44 _ all life seemed to enjoy peaceful existence with is
surroundings,” her fable begins, _ 45 _ (borrow) some familiar words from many age-old fables. Behind the simple
style, however, is a serious message _ 46 _ (intend) for everyone.
_ 47 _ (difference) from traditional fables, Carson’s story ends with an accusation instead of a moral. She warns of
the environmental dangers facing society, and she teaches that people must take responsibility _ 48 _ saving their
environment.
The themes of taditional fables often deal with simple truths about everyday life. However, Cason’s theme is a more
weighty _ 49 _ (warn) about environmental destruction. Carson proves that a simple lyric form that has been passed
down through the ages can still _ 50 _ (employ) today to draw attention to important truths.
