题目：
已知函数f（x）是奇函数，当x≤0，时，f（x）=x2-2x，那么当x＞0时，f（x）的解析式是______．
答案：
由题意可得：设x＞0，则-x＜0；
∵当x≤0时，f（x）=x2-2x，
∴f（-x）=x2+2x，
因为函数f（x）是奇函数，
所以f（-x）=-f（x），
所以x＞0时f（x）=-x2-2x，
故答案为f（x）=-x2-2x．
已知函数f（x）是奇函数，当x≤0，时，f（x）=x2-2x，那么当x＞0时，f

I remember my first Christmas party with Grandma．I remember the day when my big sister dropped the bomb: “There is no Santa Claus,” she laughed．“Even dummies know that!” I fled to Grandma because I knew she always told me 21 ．After I told her everything, she said “No Santa Claus? Don’t believe it. Now, 22 your coat, and let’s go.” “Go? Go where?” I asked． “Where” 23 to be the General Store．As we walked through its doors, Grandma 24 me ten dollars．That was a lot in those days．“Take this money and buy something for 25 needs it．I’ll wait for you in the car．” The store seemed big and 26 , full of people hurrying to finish their Christmas shopping．For a few moments I just stood there, 27 , holding that bill, wondering what to buy, and who on earth to buy it for． Suddenly I thought of Bobbie who sat right behind me．I remembered he didn’t have a coat．I fingered the bill with growing 28 ．I would buy Bobbie a coat． “Is this a Christmas present for someone?” the lady behind the 29 asked me kindly, as I laid my ten dollars down “Yes,” I replied shyly．“It’s…for Bobbie.” The nice lady smiled at me．I didn’t get any 30 , but she put the coat in a bag and wished me a Merry Christmas． That evening, Grandma helped me 31 the coat and wrote, “To Bobby, From Santa Claus” on it．Then she 32 me over to Bobbie’s house． Grandma parked down the street from Bobbie’s house, and she and I crept 33 and hid in the 34 ．Then Grandma gave me a sign．“All right, Santa Claus, get going．” I took a deep 35 , dashed for his front door, threw the present down, pounded his doorbell and flew back to the safety．Together we 36 breathlessly in the darkness for the front door to open．Finally it 37 , and there stood Bobbie． Forty years haven’t dimmed the thrill of those 38 spent shivering, beside my grandma, in Bobbie’s bushes． 39 , I realized: Santa was alive and well, and we were 40 his team．
