“Jane, please let me borrow a dollar,” Jenny asked as they stood in the school lunch line. “I have one in my jacket, but I don’t want to 1 and lose my place.” “OK,” agreed Jane. Jane waited all day for Jenny to 2 back the dollar she borrowed, but Jenny always seemed to be 3 . “She’s just forgotten,” thought Jane. “I don’t want to make her angry.” Still, her money didn’t go 4 . Some classmates, like Jenny, were 5 five dollars a week. Weeks went by. At last Jane got up enough courage (勇气) to tell her about the money. “Oh Jane, I 6 !” Jenny said. “I’ll bring the dollar tomorrow.” The next day Jenny seemed to have forgotten again. During the noon hour Jane saw her buying sweets for Mary and Ann. Jenny saw Jane looking at her. 7 she said something in a low voice to the other two girls. Jane felt 8 and asked her teacher if she could go back to the classroom. In the classroom, Jane saw two new pencils in Jenny’s desk. An 9 came to her. “Jenny’s not 10 lately, and anyway, she really owes (欠) me. Besides, she has all money to buy more. A dollar doesn’t mean anything to her, but it means a lot to me.”
