下面几段话是摘自C.S.Lewis的The Horse and His Boy。当男孩Shasta发现一匹会说话的马时，他问：
"How did you learn to talk?"
"Hush! Not so loud,"replied the Horse. "Where I come from, nearly all the animals talk."
"Wherever is that?" asked Shasta.
"Narnia," answered the horse. "The happy land of Narnia - Narnia of the heathery mountains and the thymy downs, Narnia of the many rivers, the plashing glens, the mossy caverns and the deep forests ringing with the hammers of the Dwarfs. Oh the sweet air of Narnia! An hour's life there is better than a thousand years in Calormen."
我们比较熟悉的是down作为副词的用法，如: get down, sit down.
但是down作为名词的时候意思就和“下”无关。
thymy:adj.麝香草的, 像麝香草的
the downs: low round hills covered with grass, as in the south of England
- Longman
the thym downs是指长满麝香草的山丘。
down jacket就是冬天穿的羽绒衣。down:(noun)2 [uncountable] the soft fine feathers of a bird
Plashing glen - 水花飞溅的峡谷
mossy caverns - 长满青苔的洞穴。
