And I added: 39。 she went on, still looking at me.39。You like Sophie, don39。I felt awkward, and looked at my shoes. I couldn39。You39。s had when she was trying not to cry. Her own thoughts were all worry and shapelessness as she kept looking at me. I tried again, but still couldn39。 though quite why she should be so worried was not, at first, clear to me. I was surprised by her, for there had been no sign before that she could think in that way. I thought back to her, trying to reassure her and show her that she need not be anxious about me, but the thought didn39。s lap. Watched her mother pause to look down at it for a still moment, lift it, bend to kiss it gently, and then look up with tears in her eyes. I felt sorry for her distress, and for Sophie, and for the hurt foot — but nothing more.While the bandaging was finished I looked round the room curiously. The house was a great deal smaller than my home, a cottage, in fact, but I liked it better. It felt friendly. And although Sophie39。And so on again.I knew it all, word for word — and yet the sight of Sophie39。Then God created woman, also, and in the same image, but with these differences, according to her nature: her voice should be of higher pitch than man39。And God created man in His own image. And God decreed that man should have one body, one head, two arms and two legs: that each arm should be jointed in two places and end in one hand: that each hand should have four fingers and one thumb: that each finger should bear a flat fingernail. . .39。Sophie climbed on to her mother39。 Oh, well, it can39。t do it myself, and it did hurt so.39。I39。Yes,39。s seen it?39。 she said, holding her and kissing her. Then she added: 39。I led her by the way I had e. At the sound of her voice Sophie crawled out of the bushes.Her mother looked at the swollen, misshapen foot and the bleeding knees.39。She looked hard at me again for a moment, then she leant the broom she was holding against the wall, and asked briskly:39。 she exclaimed. 39。I told her.39。 I asked.She looked at me sharply and frowned. She said, with anxious abruptness:39。Are you Sophie39。 she said.I walked beside her, carrying the shoe, and feeling useless. She kept going gamely for a surprisingly long way, but she had to give it up. Her trousers were worn through at the knees, and the knees themselves were sore and bleeding. I had never known anyone, boy or girl, who would have kept on till that pitch。No. I39。ll have to go and fetch somebody to help,39。t even notice then that it had more than the usual number of toes. . . .I managed to hammer the shoe out of the cleft, and handed it to her. But she found she could not put it on her swollen foot. Nor could she put the foot to the ground. I thought I might carry her on my back, but she was heavier than I expected, and it was clear that we should not get far like that.39。Never, never! Promise?39。t ever tell,39。 she said, looking at me fearfully through her tears, so I knelt down to see what I could do about it.39。I can39。t look.39。 ASP 網(wǎng)頁設(shè)計(jì)技巧與網(wǎng)站維護(hù)》,清華大學(xué)出版社,[15] Abbott K.
