When can my bike be repaired?我的自行車什么時候能修好？ Who might be sent abroad for further education?誰有可能被送去國外進修？三、 如何正確使用被動語態(tài)1. 有些動詞帶有兩個賓語，即直接賓語和間接賓語，變被動語態(tài)時，可把其中一個賓語變成主語，另一個留在被動結構謂語后面。需要注意的是：若把直接賓語變成被動語態(tài)的主語，需要在間接賓語之間加上介詞“to”。eg. He often tells us interesting stories . （主動語態(tài)） （被動語態(tài)）常帶雙賓語的詞有：tell , show , lend , pass等。2. 在主動語態(tài)中，某些動詞之后帶有復合賓語，即賓語和賓語補足語，這個復合賓語由動詞不定式來充當，to被省略，但在被動語態(tài)中，這個to還要還原。eg. I often hear her sing this popular song . （主動語態(tài)） She is often heard to sing this popular song .（被動語態(tài)） 有這種用法的常用動詞有：make , let , see , hear , watch , feel , notice等。3. 有些“be +過去分詞”的結構并不是被動語態(tài)，它們有可能是“系表結構（即系動詞之后由過去分詞來充當表語）。”比較：（1）（2）4. 只有及物動詞和可有賓語的動詞+介詞詞組才可以有被動語態(tài)。eg. 四、主動語態(tài)變?yōu)楸粍诱Z態(tài)轉換圖示：主動語態(tài)與被動語態(tài)之間如何轉換 主動句:主語(人/物) + 謂語(及物動詞) + 賓語(人/物) + 其他 + 狀語 (動作的執(zhí)行者) (各種時態(tài)形式) (動作的承受者) 被動句:主語(人/物) + 謂語(及物動詞) + by +人 / 物 + 其他 + 狀語 (動作的承受者) (be +過去分詞) (動作的執(zhí)行者) We Visited that factory last summer 主動語態(tài)主語 謂語 賓語 狀語That factory was visited by us last summer 被動語態(tài) 主語 謂語 賓語 狀語1、主動語態(tài)變?yōu)楸粍诱Z態(tài)的步驟：（1）將主動句的賓語變?yōu)橹髡Z，如果主動句的賓語是代詞，需變?yōu)橹鞲?。?）將動詞改為“be+過去分詞”，be與新主語的人稱和數(shù)一致，時態(tài)不變。（3）將主動語態(tài)的主語前加by放在謂語動詞后，如果原主語是代詞，要變?yōu)橘e格。 They held a meeting yesterday. A meeting was held（by them）yesterday. They wont forgive me. I wont be forgiven by them.2、主動語態(tài)變?yōu)楸粍诱Z態(tài)的注意事項：（1）主動句中的主語如果是people, we, you, they, somebody等含糊地表示“人們”、“大家”等， 變?yōu)楸粍泳鋾r，通常刪去“by”，除非強調(diào)原主語。如： They set up this hospital in 1975. This hospital was set up in 1975. Only he can finish the job. 只有他能完成這項工作。 The job can be finished only by him.這項工作只能由他來完成。（2）含有賓語從句的主動句變?yōu)楸粍泳?，通常用it作為被動結構的先行主語，把賓語從句后置。 We have determined that the plan should be carried out soon. It has been determined that the plan should be carried out soon.五、高頻考點：1. 動詞的主動形式表示被動之意1）某些連系動詞，如：look, feel, smell，sound, prove等。 The flower smells sweet.這花聞起來很香。Maria proves very patient and warm-hearted. 瑪麗亞被證明很耐心、很熱心2）表示主語內(nèi)在“品質(zhì)”或“性能”的某些動詞，雖然可以是及物動詞，但這時用作不及物動詞， 如：lock, shut, close, open, move, read, write, sell, wash, clean, draw, cut, translate, burn, run, ride, begin, end, operate等。 The sentences translate hard. 這些句子很難譯。 The door wont shut. 這個門關不上。3）某些動詞用在句型“主+謂+主補”時，如wear，blow，prove等。 The door blew open. 門被吹開了。2. 不用于被動語態(tài)的動詞有些動詞用于被動語態(tài)，如happen，cost，take，have (有)，own，possess, want。An accident happened yesterday. 昨天發(fā)生了一起事故。One should possess courage, determination and wisdom. 人要擁有勇氣、決心和智慧。3. “動詞+反身代詞”結構與“be+過去分詞”結構注意下面短語：devote oneself to (獻身于) seat oneself (就坐) dress oneself (穿衣),amuse oneself (自娛自樂) lose oneself (迷路) prepare oneself for (做好心理準備),concern oneself about (擔心)這些短語經(jīng)常用被動結構表示主動意義。They were seated in the front of the hall. 他們在大廳前部就坐。He was concerned about his work. 他擔心他的工作。All my students are well prepared for the test. 我的學生都為考試做好了準備。His mother is dressed in white at the party. 他的媽媽在宴會上穿著白色衣服。4. be done與get done1）現(xiàn)代英語特別是口語中常用“get + 過去分詞”表示被動語態(tài)。2）“get + 過去分詞”只表示動作，而“be+過去分詞”既可表動作，也可表狀態(tài) They have been married for ages. 他們結婚多年了。（不能用get married） They got married last month. 他們上個月結婚了。3）經(jīng)過安排、考慮的動作用“be+過去分詞”；出乎意料時用“get+過去分詞” How did the painting get damaged? 這幅畫什么時候被損壞的？4）“be+過去分詞”是單純的被動意義，而“get+過去分詞”可以暗示主語對動作的發(fā)生有一定的責任，含有某種主動意味。 His team got beaten again though they had tried their best. 雖然他們盡了全力，他的隊還是輸了。5. 幾個被動語態(tài)常用習慣用法：Were determined to set up an eco-laboratory. 我們決定建立一個生態(tài)實驗室My time was occupied with children. 我的時間都用在了孩子們身上。Im very interested in fine arts. 我對美術非常感興趣。Where was your grandfather born? 你祖父的出生地是哪里？I was graduated from that university ten years ago. 我十年前從那所大學畢業(yè)。My hometown is situated in the south of China. 我的家鄉(xiāng)在中國南部。6It is said/ reported/believed, etc. + 從句的變化： 常見的句型結構：It is(was)agreed(believed/decided/hoped/thought.）that.大家同意（相信、決定、希望、認為）.It is(was)well known that.眾所周知It is(was)taken for granted that.被視為當然It must be remembered that.務必記住.It mustnt be forgotten that.千萬別忘記.It is(was)said(reported，heard，told，suggested)that.據(jù)說(報道、聽說、告知、建議.)“It is said/ reported/believed, etc. + 從句”表示據(jù)說/據(jù)報道/據(jù)信.，此句型可以變成從句主語作主語的句型：sb. be said/ reported/believed, etc. +不定式。如果原來從句的謂語動作已經(jīng)完成，不定式用完成式；如果從句的謂語動作是經(jīng)常性動作或還沒有完成，用不定式的一般式。It is said that James is an expert on DNA. = James is said to be an expert on DNA.人們說詹姆斯是個DNA專家。It is said that the boy has passed the national exam. =The boy is said to have passed the national exam.據(jù)說這個男孩已經(jīng)通過了這次全國性的測試。鞏固練習. 單項選擇1.
