My friend Michelle is blind, but you’d never know it. She makes such good use of her other __1 , including her “sixth sense”, that she seldom gives the impression (印象) that she’s 2__ anything. It’s really amazing. Michelle 3 her children pretty much like the rest of us, except that she isn’t too hard on them. Her children really benefit a lot from her 4 __attitude. She knows when to clean the house, and she moves around so fast that 5 often don’t realize she’s blind. I 6 this the first time after my six-year-old daughter, Kayla, went to play there. When Kayla came home, she was very 7 about her day. She told me they had baked cookies, played games and done art projects. But she was 8 excited about her finger-painting project. “Mom, guess what?” said Kayla, all smiles. “I learned how to 9 colors today! Blue and red make purple, and yellow and blue make green! And Michelle 10 with us”. To my great 11 , my child had learnt about color from a blind friend! Then Kayla continued, “Michelle told me my 12 showed joy, pride and a sense of accomplishment (成就). She really 13 what I was doing!” Kayla said she had never known how good finger paints felt 14 Michelle showed her how to paint without looking at her paper.

At first, she didn’t believe me. “But Mommy, Michelle knew exactly what was in my picture!” Kayla __17 . I knew my child was _18 because Michelle had listened to Kayla describe her art work. Michelle had also “heard” Kayla’s 19 in her work. We were silent for a minute. Then Kayla said slowly, “You know, Mommy, Michelle did ‘see’ my picture. She just used my __20__.” Indeed, she uses a special type of “vision” that all mothers have.
