She makes such good use of her other    , including her “sixth sense”,   she rarely gives the impression she’s missed anything.   Michelle looks after her children pretty much like the rest of us, except that she doesn’t push too hard on them, who really benefit a lot from her relaxed attitude. She knows when to clean the house, she moves around so fast that often the    don't realize she's blind.   I realize this the first time after my six-year-old daughter, Kayla, went to play there. When Kayla came home, she was very   about her day. She told me they had baked cookies, played games and done art projects. But she was   excited about her finger-painting project.   “Mom, guess what?”said Kayla, all smiles. “I learned how to      colors today! Blue and red make purple, and yellow and blue make green!

She really      what I was doing!’’ Kayla said she had never felt how good finger paints felt      Michelle showed her how to paint without looking at her paper.   I realized Kayla didn’t know that Michelle was blind. It had just never come up in conversation.   When I told her, she was      for a moment. At first, she didn’t believe me. “But Mommy, Michelle knew exactly what was in my picture!” Kayla     . And I knew my child was      because Michelle had listened to Kayla describe her artwork. Michelle had also heard Kayla's pride in her work.   We were silent for a minute.Then Kayla said slowly, “You know, Mommy, Michelle really did ‘see’ my picture. She just used my      .’’ Indeed, she uses a special type of “vision” that all mothers have. 1.A.ways      B.means         C.methods      D.senses   2.A.which     B.when          C.that          D.as 3.A.guests     B.family         C.children      D.friends 4.A.excited    B.sad            C.satisfied      D.enjoyed 5.A.especially  B.not so          C.a little       D.not at all 6.A.paint      B.draw           C.mix         D.create 7.A.stayed     B.painted         C.talked       D.played 8.A.excitement  B.encouragement  C.delight       D.surprise 9.A.attitude     B.color           C.picture      D.paper 10.A.touched    B.distinguished    C.saw         D.understood 11.A.after      B.before          C.until         D.when 12.A.curious    B.quiet           C.puzzled      D.worried 13.A.cried      B.insisted         C.complained   D.informed 14.A.right      B.wrong          C.worried       D.uncertain 15.A.paper     B.pens            C.hands        D.eyes
