你拿胶卷去冲洗了没有？ 4. “with 宾语过去分词”结构中，过去分词用作介词 with 的宾语补足语。这一结构通常在句中作时间、方式、条件、原因等状语。例如：the murderer was brought in, with his hands tied behind his back. 凶手被带进来了，他的双手被绑在背后。（表方式）with water heated, we can see the steam. 水一被加热，我们就会看到水蒸气。（表条件）with the matter settled, we all went home. 事情得到解决，我们都回家了。（表原因）注意：在这一结构中，当宾语为某一身体部位，且作宾补的动词是及物动词时，身体部位通常是过去分词的逻辑宾语，因而过去分词不可换用现在分词。she stood in front of him, with her eyes fixed on his face. 她站在他面前，眼睛注视着他（ fix ones eyes on 为固定短语，因此，不可将句中 fixed 换为 fixing ）he stood for an instant with his hand still raised. 他仍然举着手站了一会儿。当用某些不及物动词的分词形式作身体部位的宾补时，用现在分词的形式。she felt her heart beating fast. 她觉得心跳很快。（beat 意为“心跳”，是不及物动词）三、掌握“使役动词 have + 宾语过去分词”的几种含义在“ have 宾语过去分词”结构中，过去分词作宾语补足语，have 也可用 get 。这一结构具有以下几种含义：1. 意为“主语请别人做某事”。例如：he wants to have his eyes examined tomorrow. 他明天想去检查眼睛。（“检查”的动作由医生来进行）2. 意为“主语遭遇、遭受某一不愉快、不测的事情”。例如：be careful, or youll have your hands hurt. 当心，否则会弄伤手的。3. 意为“使完成某事”，事情既可以是别人做完，也可以由主语参与完成。例如：he had the walls painted this morning. 他今早把墙漆了。（主语自己可能参与）四、区分过去分词作宾语补足语与现在分词作宾语补足语一般说来，过去分词作宾语补足语时，宾语是动作的承受者；现在分词作宾语补足语时宾语是动作的执行者。试比较：i found him lying on the grass just now. 我刚才发现他躺在草坪上。i found him knocked down by a car. 我看到他被车撞了。五、过去分词与不定式，现在分词作宾语补足语的区别三者与宾语逻辑上都是主谓关系,但是过去分词强调他们之间的被动关系,不定式强调动发生的全过程,现在分词强调它们之间的主动关系. i saw her come into the classroom. i saw her coming into the classroom. i saw her taken out of the classroom. the missing boys were last seen near the river. a. playing b. to be playing c. play d. to playstep 4. consolidation（work in groups of 4, and have a competition）page 50. using structures exercise 11. ask students to work in pairs of four. 2. give them five minutes to finish the work and ask each group to choose the best answers. let leader of each group read the best sentences they have written. 3. ask students to choose the best sentences. exercise 21. give them five minutes to finish the work. 2. two in pairs exchange and talk about their answers. 3. teacher gives the keys. step 5. a quiz i. choose the best answers. 1. with trees, flowers and grass_ everywhere, my native town had taken on a new look. a. planting b. planted c. to plant d. to be planted2. is this the recorder you want_?a. to have repaired b. to repair it c. to have it repaired d. it repaired3. she was glad to see her child well care of. a. take b. to be taken c. taken d. taking4. he found them_ at a table chess. a. sat; to play b. sitting; to play c. seated; playing d. seat; play the5. i can make you w hat i say, but you cant make yourself in english. a. understand; understand b. understand; understood c. to understand; understand d. understand; to be understood6. john rushed out in a hurry, the door . a. leaving; unlocked b. leaving; unlocking c. left; unlocked d. to leave; unlocking7. i have had my bike , and im going to have somebody my radio tomorrow. a. repair; to repair b. repairing; to be repaired c. repaired; repair d. to repair; repairing8. the room ,the nurse found the tape recorder. a. entering; stealing b. entering; gone c. to have entered; being stolen d. having entered; to be stolen9. we are pleased to see the problem so quickly. a. settled b. settling c. be settled d. having been settled10. i have often heard the abc song, but i have never heard alice it. a. to be sung; to sing b. being sung; sang c. sung; sing d. sang; singing11. good morning. can i help you?
