He was born in 1995. b. When I was a child , I was taken to Shanghai once Suggested answers: past simple 有兩個特點，一是表示動作或狀態(tài)發(fā)生在過去，而不是現(xiàn)在，常伴有表示過去的時間狀語；二是說話人在心中對動作發(fā)生或狀態(tài)存在的時間是明確的。 2. a.. We had learnt four thousand new words by the end of last year. b. They had no sooner got home than it began to rain. Suggested answers: past perfect 表示動作或狀態(tài)延續(xù)到過去某一時間，通常使用具有延續(xù)意義的動詞，常帶有如by(the end of) +過去某時刻, since, for, when, before等時間狀語表示某動作或狀態(tài)在過去某時之前結束了，但其影響延續(xù)至當時，通常使用短暫性動詞. 3. a. At this moment yesterday, I was packing for camp. b. What were you doing at eight last night? Suggested answers: past continuous 表示某個時間正在發(fā)生、進行的動作。句子常有表示“過去某個時間點”的狀語。 溫馨提示 請注意找出時間的參照點。 Step 2 觀察思考三種時態(tài)間的區(qū)別(小組活動) 1. 一般過去時與過去進行時的區(qū)別 Mary wrote a letter to her friend last night. Mary was writing a letter to her friend last night. 歸納總結： ___________________________________________________________________________ ___________________________________________________________________________ Suggested answers: 一般過去時表示過去已經發(fā)生的動作或存在的狀態(tài)，強調一種事實或結果；而過去進行時表示過去某時正在持續(xù)進行的動作或尚未完成的動作，強調過程。 2. 一般過去時與過去完成時的區(qū)別 They had done the work at five o’clock. They did the work at five o’clock. 歸納總結： ___________________________________________________________________________ ___________________________________________________________________________ Suggested answers: 一般過去時表示動作發(fā)生在過去某時(其時間參照點是現(xiàn)在)，而過去完成時則表示動作發(fā)生在過去某時之前(其時間參照點是過去)。 鞏固案（10分鐘） Step 1和Step 2限時完成（個體）→核對答案（個體）→研究錯題原因（小組） Step 3個人寫作，小組互改 (課后進行) Step 1 Ask Ss to complete the passage with the correct form of the verbs in Activity 4.
