 I　didn’t　cry　when　I　learned　I　was　the　parent　of　a　disabled　child.　I　just　sat　still　and　didn’t　say　anything.

    When　Jenny　was　old　enough,　I　sent　her　to　a　kindergarten（幼儿园）.　On　the　first　morning,　Jenny　spent　hours　playing　by　herself.　It　seemed　that　she　felt　very(41).

    However,　to　my　joy,　Jenny’s　classmates　always　(42)　her,　“You　got　al　your　speling　words　right　today!”In　fact,　her　speling　list　was　the　(43).　Later,　she　faced　a　very　painful　(44)　—— at　the　end　of　the　term,　there　was　a　game　which　had　(45)　to　do　with　physical　education.　But　Jenny　was　(46)　in　it.

    But　as　it　was　her　turn　to　join,　a　change　took　place　in　her　(50).　The　talest　boy　behind　Jenny　placed　his　hands　on　her　waist（腰）.　Two　other　boys　(51)　in　front　of　her.　The　moment　the　player　before　Jenny　stepped　out　from　the　sack,　the　two　boys　(52)　the　sack　suddenly　and　kept　it　open　while　the　tal　boy　lifted　Jenny　and　(53)　her　into　it.　A　girl　nearby　took　her　hand　and　supported　her　(54)　Jenny　got　her　balance.　Then　she　jumped　forward,　smiling　and　proud.　In　the　cheers　of　the　teachers,　schoolmates　and　parents,　I　silently　 thanked　 the　 warm,　understanding　people　in　life　who　made　it　 (55)　for　my　disabled　daughter　to　be　like　her　felow　human　beings.　Then　　I　finaly　cried.
