3、續(xù)到現(xiàn)在的動(dòng)作或保存的狀態(tài)。●現(xiàn)在完成時(shí)的構(gòu)成:現(xiàn)在完成時(shí)是由“助動(dòng)詞have/has+動(dòng)詞的過去分詞”構(gòu)成。助動(dòng)詞要和主語(yǔ)的人稱、數(shù)保持一致。一般疑問句：have/has…?Yes,Ihave.No,Ihaven’t.Yes,shehas.No,shehasn’t.havebreakfastI’mnothungrynowmovedherein2004Istillliveherenowpast現(xiàn)在完成時(shí)現(xiàn)在完成時(shí)態(tài)可用于表達(dá)剛剛做完某事或已經(jīng)做完某事,常見的標(biāo)志詞有already,yet等。下面我們一起看看這幾個(gè)詞的用法:(
4、1)already意為"已經(jīng)",常放在have/has和動(dòng)詞之間,通常用于肯定句中。如:Theyhavealreadyarrivedatthehospital.他們已經(jīng)到達(dá)醫(yī)院了。already也可用于疑問句，表示期望得到肯定的回答或表示驚異，此時(shí)常放在句末。(2)yet多用于否定句中,意為"還(沒)"；也常用于疑問句中,意為"現(xiàn)在,已經(jīng)"。如:Thesunhasnotrisenyet.太陽(yáng)還沒有升起。Hasthemanfinishedtheworkyet?這個(gè)男人做完工作了嗎?Don’tworryabouthim.Heha

6、?D.already,already分析：此題應(yīng)該選用B項(xiàng)。前面為疑問句，后面是否定回答，故兩處空格均應(yīng)該用yet。B()---HasJim____cleanedhisbedroom?---Yes,hehascleanedit________.A.just,yet????B.already,justC.just,already???D./,already分析：此題應(yīng)該選用D項(xiàng)。前面為疑問句，一般不用just/already提問，故A、B、C項(xiàng)都是錯(cuò)誤的，后面是肯定結(jié)構(gòu)，故應(yīng)該用already。D()Jim,haveyouha
7、dyourlunch______?It’sonly10:30inthemorning.A.yet????B.justnowC.just????D.already分析：此題應(yīng)該選用D項(xiàng)。前面為疑問句，但是從“It’sonly10:30inthemorning.”中可以看出問話人非常驚訝，故應(yīng)該用already連接。D動(dòng)詞的過去式的變化和過去分詞的變化并不完全相同。我們對(duì)它們作了一個(gè)大致的分類。(注：例子中單詞的變化順序?yàn)椋簞?dòng)詞原形→動(dòng)詞的過去式?→動(dòng)詞的過去分詞)一、過去式和過去分詞的變化相同規(guī)則變化：一般在動(dòng)詞詞尾直接加ed
8、。如：pick→picked→picked;wish→wished→wished;stay→stayed→stayed2.以不發(fā)音的e結(jié)尾的動(dòng)詞后面加d。如：like→liked→liked;hope→hoped→hoped;phone→phoned→phoned3.以“輔音字母+y”結(jié)尾
