His difficulty in walking ____ a childhood illness.

already skilled in Latin after seven years of studying it as his second language at St.Paul’s School London.Like all English boys who prepared for college in grammar schools he had learned not only to read Latin but also to speak and write it smoothly and correctly.His pronunciation of Latin was English however and seemed to have sounded strange to his friends when he later visited Italy.

Schoolboys gained their skill in Latin in a bitter way.They kept in mind the rules to make learning by heart easier.They first made a word-for-word translation and then an idiomatic translation into English.As they increased their skill they translated their English back into Latin without referring to the book and then compared their translation with the original.The schoolmaster was always at hand to encourage them.All schoolmasters believed Latin should be beaten in .

After several years of study the boys began to write compositions in imitation of the Latin writers they read.And as they began to read Latin poems they began to write poems in Latin.Because Milton was already a poet at ten his poems were much better than those painfully put together by the other boys.During the seven years Milton spent at university he made regular use of his command of Latin.He wrote some excellent Latin poems which he published among his works in 1645.

One day, the principle（校长)came into our room and, after talking to the teacher, for

some reason said: “I wish all of the white students to stand for a moment.” I rose with the others.The teacher looked at me and, calling my name, said: “You sit down for the present, and rise with the others.” I did not quite understand her.She repeated: “You sit down now, and rise with the others.” I sat down puzzled.I saw and heard nothing.When the other were asked to rise, I did not know it.When school was dismissed, I went out unconsciously.A few of the white boys laughed at me, saying: “Oh, you’re a nigger, too.”

I hurried on as fast as I could to where my looking-glass hung on the wall in my own little room.For an instant I was afraid to look, but when I did, I looked long and earnestly.I was accustomed t o hearing remarks about my beauty, but now, for the first time, I became conscious of it and recognized it.I noticed the ivory(象牙)whiteness of my skin, the beauty of my mouth, the size and the liquid darkness of my eyes.I ran downstairs and rushed to wh ere my mother was sitting.I buried my head in her lap and cried out: “Mother, tell me, am I a nigger？” I could not see her face, but I felt her hands on my head.I looked up into her face.There were tears in her eyes and I could see that she was sufferin g for me.And then it was that.

I looked at her critically for the first time.I had thought of her in a childish way only as the most beautiful woman in the world; now I looked at her searching for defects(缺点).I could see that her skin was almost brown,and that she did differ in some way from the other ladies who came to the house; yet, even so I could see that she was more beautiful than any of them.She must have felt that I was examining her, for she hid her face in my hair and said with difficulty：“No, my darling, you are not a nigger.” She went on: “If anyone calls you a nigger, don’t notice them.”

But the more she talked, the less was I reassured, and I stopped her by asking:“Well, mother, am I white？ Are you white？” She answered tremblingly(颤抖的): “No, I am not white, but your father is one of the greatest men in the country.The best blood of the South is in you.” This suddenly opened up in my heart a fresh fear, and I almost fiercely demanded: “Who is my father？ Where is he？” She stroked my hair and said: “I’ll tell you about him some day.” I sobbed(抽泣): “I want to know now.” She answered: “No, not now.”
