Fables were part of the oral tradition of many early cultures, and the well-known Aesop’s fables date to the 2 (six) century, B. C. Yet, the form of the fable still has values today, 3 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, 4 all life seemed to enjoy peaceful existence with is surroundings,” her fable begins, 5 (borrow) some familiar words from many age-old fables. Behind the simple style, however, is a serious message 6 (intend) for everyone. 7 (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 8 saving their environment. The themes of traditional fables often deal with simple truths about everyday life. However, Cason’s theme is a more weighty 9 (warn) about environmental destruction. Carson proves that a simple lyric form that has been passed down through the ages can still 10 (employ) today to draw attention to important truths. 1. to teach 用不定式作目的状语 2. sixth century“世纪”前面要用序数词 3. as 引导非限定性定语从句 4. where 非限定性定语从句作地点状语 5. borrowing 逻辑主语her fable与borrow之间为主动关系 6. intended 在句中作定语，be intended for打算为……所用 7.
