2、解】1現(xiàn)在完成時：1)含義：表示動作過去發(fā)生，但與現(xiàn)在有聯(lián)系或影響，此時態(tài)常與以下時間詞連用，如already已經(jīng),yet已經(jīng)，還，just剛剛,ever曾經(jīng),so far到目前為止,before從前,times次數(shù),for+時間段，since自從以來,how long多久，never從不，in the past.在過去.2)結(jié)構(gòu)：主語+have/has+動詞的過去分詞（have/has是助動詞，沒有“有”的意義）肯定句：She has finished her work.她完成了她的工作。一般疑問句：Has she finished her work? _Yes, she has./No,

3、she hasnt.否定句: She hasnt finished her work. 3)動詞的過去分詞的構(gòu)成：規(guī)則動詞的過去式就是過去分詞，不規(guī)則動詞的過去分詞見不規(guī)則動詞表。4)現(xiàn)在完成時態(tài)與一般過去時的區(qū)別：句子中如有yesterday, last, just now,in1999等過去時間詞出現(xiàn)就只用一般過去時。5)特別提醒：句子中如有when出現(xiàn)，一定不能用完成時例題：A :Jack has read the book, B :When did he read it?
