1、Unit 3 Celebration 語法篇1 、掌握一般現在時|，一般過去時|，一般將來時|，過去將來時|，現在進行時|，過去進行時|，現在完成時|，過去完成時及其被動語態的用法|。2 、掌握情態動詞 must|， have to|， can|，could 及 ought to 的用法|。一，被動語態1. 被動語態的概念：當句子的主語是動作的承受者時|，謂語的形式叫做被動語態|。2. 被動語態的構成：助動詞 be （或get） +過去分詞|,助動詞be （或get）有時態|,人稱和數的變 化 |。3. 被動語態的形式：一般現在時：am/is/are done一般過去時：was/were do

2、ne一般將來時：will/shall be done過去將來時：would be done現在進行時：am/is/are beingdone過去進行時：was/were beingdone現在完成時：has/have been done過去完成時：had been done經典例句： Fast food is served here. 這兒賣快餐|。The new film will be shown next week.這部新電影將會在下周放映|。 The concert has been put off till next week. 音樂會已經被推遲到下周了|。4 .何種情況下使用被動語

3、態：當不知道或沒有必要說出動作的執行者|,或者動作本身更為重要時|,動詞使用被動語態|。例：Too much books have been written about the Second World War.關于第二次世界大戰的書太多了|。5 .主動形式表被動意義：系動詞100k|, sound|, feel|, smell|, taste等+形容詞構成系表結構：Steel feels cold.鋼摸起來很涼|。表示主語的某種屬性特征的動詞|,如 read|, write|, wash|, sell|, wear|, cook|, lock|,shut|, open|, dry|, dri

4、nk等|,這類動詞一般不單獨使用|,常有副詞修飾：The cloth washes well.這種布料好洗 |。表示開始 |,結束 |,運動的動詞 |,如：begin|, start|, end|, finish|, close|, stop|, move|, run 等：Work begins at 7 o clock in the morflng. 7 點開始工作 |。二，情態動詞1. have to/don t haVefio /不必have to表示“不得不”|,指在客觀條件下不得不去做某事；否定式 don have to表示“沒必要|,不必” |,有時態和人稱的變化|。易混辨析：mu

5、st:表示“必須|,應該 |,語氣強烈|。回答帶有 must的問句時|,否定回答常用 needn 或don t have to|表示不必”|,而mustn 的 含義是“禁止|,不準” |。表示有把握的推測|,意為“一定|,準是” |,常用于肯定句|。譯為“偏要一|,非要不可” |,常表達說話人抱怨的口氣|。例：He had to work hard to support the family. 他不得不努力工作來養家|。（客觀需要）You don t have to go to school at onc你不必馬上去上學 |。You must be hungry after a long wa

6、lk.走了很長一段路 |,你一定餓了 |。（肯定推測）第2頁/共11頁2. can/ can 能 /不能can|， could （can 的過去式）的用法：can:表能力（現在）表客觀或理論上的可能性表請求和允許表推測|，常用于否定句和疑問句|， can 比 could 語氣強cannottoo/enouglfB論也不過分|,越 越好 cannot but do 不得不（ =have to do）could:表能力（過去）表推測|，常用于否定句和疑問句|，比can 語氣弱表請求和允許|。用在疑問句時比 can語氣委婉|,不表過去|。例：An experienced teacher can al

7、so make mistakes. 一個有經驗的老師也可能犯錯誤|。（客觀可能性）He can t be our manager. He has gone to Beijin也不可能是我的經理|。他去北京了 |。（否定推測）3. ought to/ ought not to 應該 /不應該表示說話者認為“應該做/不應該做”；也表示說話者根據一定的依據進行推測|，譯為“按道理說應該/不應該”|。其后跟動詞原形|，疑問式是把ought 提到主語前|。ought to 作為情態動詞|，經常考查與其不定式的完成時搭配的用法|，即：ought to have done =should have done

8、|， 表示 “本應該做了某事而實際沒有” |， oughtn t to have done = shouldn t， have done|表示“本不應該做某事而實際做了” |。Needn表示某一動作不必要做|,而ought not to表示某一動作是錯誤的|,與shouldn 類似|,但語氣更強 |。例：He ought to be more careful next time.下次他應該更小心才是|。 She ought not to let out the secret.她不該泄露這個秘密 |。You needn t go for him; he has come here沒必要去找他；他

9、已經來了|。例 1.

Shakes

10、peare s play Hamlet into at least ten different films over the past years.A. had been madeB. was madeC. has been madeD. would be made解析：句意：在過去的數年|，莎士比亞的戲劇哈姆雷特被制成不下十部不同的電影|。 over the pastyears意為“在過去的數年”|,通常情況下題干中出現overthe past years|,謂語動詞為現在完成時態 |，即可推斷出正確答案|。答案： C|。例 3.

11、if you want to do.A. mustB. mustn tC. have toD. don t have to解析：句意：你不必買禮物了|，但是如果你想買的話也可以買|。 don t have to 意為“不必”|，即可推斷出正確答案|。答案： D| 。例 4. （ 2019 北京通州高三一模） Fred had to have his car repaired in a garage because it seriously.第4頁/共 11頁A. damagedB. had been damagedC. was being damagedD. had damaged解析： 句意

12、： 因為損壞的太嚴重|， Fred 不得不把他的車放到修理廠修理|。 根據語境可知|， 動作damage應發生在repaired之前|,即過去的過去|,故用過去完成時|。且damage與car是被動關系|,應用被動語態|，即可推斷出正確答案|。答案： B|。例 5.
