现在完成时一、其构成助动词have (has) +动词过去分词构成现在完成时。如：1. Kates never seen Chinese films，_ ? A. hasnt she B. has she C. isnt she D. 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. has B. had C. did D. 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动词形式保持一致，又后句的主语为her par
