1、Module 3 Unit 1 Changing our lives ［教學(xué)過程］ 一般過去時(shí)的構(gòu)成 ★一般過去時(shí)是用動(dòng)詞的過去式來表示的。 His words fetched a laugh from all present. 他的話使在場的人都笑了。 I did not sleep well last night. 我昨晚沒睡好。 Did you direct the tourist to the hotel? 你告訴這位游客去旅館的路了嗎？ 　提　示 　在一般過去時(shí)的句子中通常都要有表示過去的時(shí)間狀語。 　【誤】I visited the Palace Mus

2、eum. （在沒有上下文的情況下，應(yīng)避免這樣說） 　【正】I visited the Palace Museum last year. 　【正】I have visited the Palace Museum. 一般過去時(shí)的用法 ①一般過去時(shí)的基本用法 ★表示過去某個(gè)特定時(shí)間發(fā)生的動(dòng)作或存在的狀態(tài)。 　　He suddenly fell ill yesterday. 　　昨天他突然生病了。 　　The engine stopped because the fuel was used up. 　　發(fā)動(dòng)機(jī)因燃料用光而停機(jī)了。 　★表示過去經(jīng)常發(fā)生的動(dòng)作或存在的狀態(tài)。 　　

3、I wrote home once a week at college. 　　我上大學(xué)時(shí)每周給家里寫一封信。 　　He was already in the habit of reading widely in his boyhood. 　　他少年時(shí)就養(yǎng)成了廣泛閱讀的習(xí)慣。 　★表示過去連續(xù)發(fā)生的一系列動(dòng)作。 　　She entered the room, picked up a magazine and looked through it carefully. 　　她走進(jìn)房間，拿起一本雜志，認(rèn)真地翻閱了起來。 　　The students went up early in th

4、e morning, did morning exercises and then read English aloud in the open air. 　　學(xué)生們很早起床，做早操，然后在室外朗讀英語。 　★在時(shí)間、條件狀語從句中表示過去將要發(fā)生的動(dòng)作。 　　We would not leave until the teacher came back. 　　老師回來我們才會離開。 　　She told me she would not go if it rained the next day. 　　她告訴我如果第二天下雨的話，她就不去了。 一般現(xiàn)在時(shí)和一般過去時(shí)的比較 　

5、　一般現(xiàn)在時(shí)要和現(xiàn)在的時(shí)間相聯(lián)系，而一般過去時(shí)和說話的“現(xiàn)在”沒有聯(lián)系。 　　His father is a film director. 　　他父親是電影導(dǎo)演。 （他現(xiàn)在還是） 　　His father was a film director. 　　他父親曾是電影導(dǎo)演。 （他現(xiàn)在不是） 　　How do you like the novel? 　　你覺得這部小說怎么樣？ （還在看小說） 　　How did you like the novel? 　　你覺得這部小說怎么樣？ （已看完小說） 一般過去時(shí)是重要語法內(nèi)容之一，同學(xué)們在學(xué)習(xí)中須認(rèn)真掌握。

6、一般說來注意以下幾點(diǎn)： 1. 表示過去發(fā)生的動(dòng)作或存在的狀態(tài)，常和表示過去的時(shí)間狀語如yesterday, last night /‘week / month / year .... ,...ago等連用。如：He was late for school last Monday. 2. 由動(dòng)詞的過去式來體現(xiàn)，動(dòng)詞be有was、were兩個(gè)過去式，was用于第一、三人稱單數(shù)，were用于其他情況。如： She was at school yesterday. They were at home last night. 3. 實(shí)義動(dòng)詞的過去式?jīng)]有單復(fù)數(shù)及人稱的變化，但一般須借助動(dòng)詞did

7、構(gòu)成其否定句及疑問句。如： They lived there two years ago. 肯定句 They didn't live there two years ago. 否定句 Did they live there two years ago？疑問句 4. 為幫助同學(xué)們記憶，現(xiàn)將其用法口訣歸納如下：（一般）過去時(shí)，表過去，過去時(shí)間常不離。 動(dòng)詞be的過去式，was、were要牢記；was用一三單，were用于其他人稱前。 否定句，was、were 后not添，疑問句，was、were提到主語前。 至于實(shí)義動(dòng)詞過去式， 否定、疑問句要靠did來周全，動(dòng)詞切記要還原。

8、 Wish的用法 1）后接動(dòng)詞不定式 I don’t wish to leave my mother. I wish to give you a good education. 2）后接含有動(dòng)詞不定式的復(fù)合賓語 You know I wish you to be happy. Why don’t you wish your son to be a teacher? 3）后接從句 I wish I were an angel. 4）后接雙賓語 wish+間賓+直賓 They wish him good luck. I wish you

9、a Happy New Year. Learn與study辨析 1）learn可用于初級階段的學(xué)習(xí)，study用于高級階段的“學(xué)習(xí)”，“研究”。 The child is learning to talk. She is at university studying law. 2）learn 可表示“學(xué)會”“學(xué)到”，“得知”，而study無此含義。 He studied hard and finally learned the lesson. I learned that he was in France. 3）“向…學(xué)習(xí)”、“從…學(xué)到”只能用learn（

10、from），而不能用study。 We must learn from Lilei. What can we learn from this story? Although 從屬連詞，引導(dǎo)讓步狀語從句，意思是“盡管…”、“雖然…”。 Although the moon is very beautiful, the earth is more important. Although still young he is going very grey. enough詞性有三個(gè)，用作代詞好掌握；定語形容修飾名，名詞前后由你定；副詞狀語表程度，必在形、副后邊行；若是用

11、在動(dòng)詞前，enough位置準(zhǔn)錯(cuò)用。 [注] 1. enough用作代詞時(shí)，作主語或賓語。 如：You have done more than enough. 你已經(jīng)做得夠多了。 I had enough. Thank you. 我吃的已經(jīng)夠多了，謝謝。 2. enough用作形容詞時(shí)，作定語，其位于名詞前、后都可以。如： I have enough time to do the work. /I have time enough to do the work. 我有足夠的時(shí)間做此項(xiàng)工作。 3. enough用作副詞時(shí)，修飾形容詞或副詞表示程度，一般放在形容詞或副詞的后邊。

12、如：long enough, easy enough, fast enough, quickly enough等；但一般不說enough long, enough easy, enough fast, enough quickly。如： The boy is old enough to go to school. 這個(gè)孩子到上學(xué)的年齡了。 4. enough用作副詞修飾動(dòng)詞時(shí)，也需放在動(dòng)詞之后。如： The meat is not cooked enough. 肉燉得不夠熟。 ［練一練］ 1.
