Kates never seen Chinese films，_ ?A. hasnt sheB. has sheC. isnt sheD. is she析：陈述句部分含否定词never,简略问句部分要用肯定式，又因Kates是Kate has的缩写，故选B。2. His uncle has already posted the photos to him. （改为否定句）His uncle _ posted the photos to him _. 析：already常用在肯定句中，yet常用在否定句、疑问句中，故填hasnt, yet。3. Ann has gone to Shanghai. So _her parents. A. hasB. hadC. didD. have析：“so+助/系/情态动词+主语”结构中的动词形式应与前句结构中的动词形式保持一致，又后句的主语为her parents是复数,故选D。二、考查其用法与标志词（一）当句中有never, ever, just, already, yet, before等时，常用现在完成时。如：1. Mum, may I go out and play basketball? _you_ your homework yet? A. Do; finishB. Are; finishingC. Did; finishD. Have; finished2. _ you _anywhere before?Yes, but I cant remember where I_A. Did; surf; surfed B. Have; surfed; surfed C. Did; surf; have surfed D. Have; surfed; have surfed析：据yet和before可知,应用现在完成时，故1题选D，2题选D。（二）当句中有“for +段时间”或“since +点时间”等时，主句常用现在完成时，谓语动词必须是延续性动词，若是非延续性动词，要改为延续性动词或表状态的词（短语）。如：1. His brother has been to Stone Forest twice _he came to Yunnan. A. afterB. beforeC. sinceD. for析：主句用的是现在完成时，而从句用的是一般过去时，故选C。2. Tom _the CD player for two weeks.A. has lentB. has borrowedC. has boughtD. has had析：A、B、C均为非延续性动词，在肯定句中不与表“段时间”的短语连用，故选D。3. I _a letter from him since he left. A. didnt receiveB. havent gotC. didnt haveD. havent heard析：据since可知，应排除A、C，“hear from sb.=receive/get/have a letter from sb.”意为“收到某人的来信”，故选B。三、考查have/has been (to, in), have/has gone （to）的区别。如：1. Have you ever _ Lintong to see the Terra Cotta Warriors?Yes, I have. A. went toB. gone toC. been inD. been to析：据句中的have，排除A，B项意为“去某地了”，C项意为“一直呆在某地”，D项意为“去过某地”，符合题意，故选D。2. My parents _ Shandong for ten years. A. have been inB. have been toC. have gone toD. have been析：本题句中有“for+段时间”结构，据此可排除C，B项意为“去过某地”，不合题意，D项缺介词，故选A4.
