The Dogs House_英语寓言故事

in the wintertime, a dog curled up in as small a space as
possible on account of the cold, determined to make himself a
house.
however when the summer returned again, he lay asleep
stretched at his full length and appeared to himself to be of a
great size.
now he considered that it would be neither an easy
nor a necessary work to make himself such a house as would
accommodate him.
