1. 表示過(guò)去發(fā)生或已經(jīng)完成的某一動(dòng)作 對(duì)現(xiàn)在造成的影響或結(jié)果。 e.g. –Have yu had yur lunch yet? –Yes, I have. I’ve just had it. (現(xiàn)在 我不餓了。)2. 表示動(dòng)作或狀態(tài)從過(guò)去某一時(shí)刻開(kāi)始，一直延續(xù)到現(xiàn)在，而且可能還要繼續(xù)下去。
e.g. I haven’t seen her these days. I’ve knwn Bb fr three years. I’ve been at this schl fr ver tw years.
時(shí)間狀語(yǔ)already, yet, just, ever, never, befre
構(gòu)成現(xiàn)在完成時(shí)是由“助動(dòng)詞have / has+ 動(dòng)詞的過(guò)去分詞”構(gòu)成的，規(guī)則動(dòng)詞的過(guò)去分詞構(gòu)成與過(guò)去式相同，不規(guī)則動(dòng)詞的過(guò)去分詞則需逐個(gè)記憶。
動(dòng)詞的過(guò)去式的變化和過(guò)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(guò)去式? → 動(dòng)詞的過(guò)去分詞)
一、過(guò)去式和過(guò)去分詞的變化相同規(guī)則變化：1. 一般在動(dòng)詞詞尾直接加ed。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; hpe → hped → hped; phne → phned → phned
3. 以“輔音字母 + y”結(jié)尾的動(dòng)詞，變y為i，再加-ed。 study → studied → studied; hurry → hurried → hurried; reply → replied → replied4. 詞尾只有一個(gè)輔音字母的重讀閉音節(jié)動(dòng)詞，要雙寫輔音字母，再加-ed。如：stp → stpped → stpped; clap → clapped → clapped
不規(guī)則變化：5. 以不變應(yīng)萬(wàn)變。如： let → let → let; put → put → put; read → read → read6. 若中間有雙寫e，則去掉一個(gè)e，單詞末尾再加t。如： feel → felt → felt; keep → kept → kept; sleep → slept → slept
7. 結(jié)尾的字母d變t。如： lend → lent → lent; build → built → built; send → sent → sent8. 變?yōu)橐?ught或-aught結(jié)尾。如： buy → bught → bught; bring → brught → brught; catch → caught → caught; teach → taught → taught
1. 肯定句：主語(yǔ) + have / has + 過(guò)去分詞 (+ 其他)2. 否定句：主語(yǔ) + have / has + nt + 過(guò)去分詞(+ 其他)3. 一般疑問(wèn)句：have/ has + 主語(yǔ) + 過(guò)去 分詞(+ 其他)
4. 特殊疑問(wèn)句： 特殊疑問(wèn)詞 (不是句子主語(yǔ)) + have / has + 主語(yǔ)+過(guò)去分詞 (+ 其他)2) 特殊疑問(wèn)詞(是句子主語(yǔ))+have / has+ 過(guò)去分詞(+ 其他)
already和yet都可以作為現(xiàn)在完成時(shí)的標(biāo)志詞，但它們的用法不同?！鬭lready一般用于肯定句中。 We have already cleaned up ur classrm. 注意：already用于疑問(wèn)句中時(shí)通常表示驚奇。 Have yu finished yur hmewrk already? I can’t believe it.◆yet一般用于疑問(wèn)句和否定句中。 Have yu seen her yet? The bus hasn’t cme yet.
表示過(guò)去發(fā)生的動(dòng)作對(duì)現(xiàn)在產(chǎn)生的結(jié)果或影響
表示過(guò)去發(fā)生的動(dòng)作一直延續(xù)到現(xiàn)在且有可能繼續(xù)下去的動(dòng)作或狀態(tài)。
