5、t have just receivedyet以上我們已經通過歸納總結和練習對本課的語法內容有了一定的了解, 下面就讓我們根據之前練習的考察情況進一步選擇講解該語法項的重難點。語法講解現在完成時如何用呢？當我們要表達“某人曾經做過某事”, “某人已經做了某事”等意思時, 英語要用“現在完成時”來表達。現在完成時(2)Grammar現在完成時的結構：has/have + done (動詞過去分詞)肯定句否定句疑問句I / We/ You / They have doneI /We/You /They have not (havent) doneHave you/they done?He/She

6、has doneHe/She has not (hasnt) doneHas he/she done?表達“剛剛做完某事”、“已經做完某事”時，使用現在完成時。如:I have just heard the news.我剛聽到消息。Astronauts have already been to the moon.宇航員已經去過月球了。We have just started to explore other planets.我們才剛剛開始探索其他行星。just “剛剛”，already “已經”，兩者都用于肯定句中，一般置于have/has之后。否定句中則用yet, 表示“還（未）”。如：Th

7、e scientists have not heard from it yet.科學家還沒有收到它發出的信息。Man has not discovered any life in space yet.人類尚未在太空中發現生命。already, just, ever, yet, never already, just ever, yet, never常與現在完成時連用的副詞：肯定句:疑問句和否定句: yet 常置于句末。already, never, ever, just 一般置于助動詞have/has之后，過去分詞之前。A: Have you ?B: Yes, / No, (using alr

8、eady, just, ever, yet, never)現在完成時與一般過去時現在完成時表示該事件是在現在之前 的某一個時間里發生的， 重點在于強調這一動作與 現在的影響一般過去時只表示過去的某一具體時 間發生的事情I have just been to London. I went there last month.我剛去過倫敦，是上個月去的。I have already finished my homework. I finished it an hour ago.我已經寫完作業了，一個小時之前完成的。A: Where have you put my book? I cant find

9、it.B: I put it on your desk yesterday. 當 A 問對方把自己的書放在何處時，他在意的是書目前在哪兒，故用現在完成時。B的回答著重的是當時的動作，故用一般過去時。無明確過去時間狀語時，判斷使用現在完成時還是一般過去時的標準是：看該行為是否對現在有影響，即該句強調或在意什么，著重點就在那里。A: Would you like to go and see the film with me tonight?B: Sorry, I _ it already.
