阅读理解。

     I was born in Tuckahoe, Talbot Country, Maryland. I have no accurate (准确的) knowledge of my age,

never having seen any record containing it. By far the larger part of the slaves know as little of their ages as

horses know of theirs, and it is the wish of most masters within my knowledge to keep their slaves thus

ignorant (不知情的). I do not remember having ever met a slave who could tell of his birthday. They seldom

come nearer to it than planting-time, harvesting, springtime, or autumntime. A lack of information concerning

my own was a source of unhappiness to me even during childhood. The white children could tell their ages,

but I could not tell. Why the same right ought to be taken away from me! I was not allowed to ask my master

about it. He considered all such questions on the part of a slave improper and impolite. The nearest estimate

(估计) I can live makes me now between twenty-seven and twenty-eight years of age. I come to this, from

hearing my master say, some time during 1835, I was about seventeen years old. My mother was named

Harriet Bailey. She was the daughter of Isaac and Betsey Bailey, both colored, and quite dark.

     My father was a white man. The opinion was also whispered that my master was my father; but of the

correctness of this opinion, I know nothing and I have no means to know. My mother and I were separated

when I was but an infant-before I knew her as my mother. It is a common custom, in the part of Maryland

from which I ran away, to part children from their mothers at a very early age. Frequently, before the child

has reached its twelfth month, its mother is taken from it,and hired out on some farm a considerable distance

off, and the child is placed under the care of an older woman, too old for field labor.
