Let ’s hurry up.剩余的时间不多了, 我们赶快吧。*We are interested in the problems concerned and want to find out more information.我们对有关的问题很感兴趣, 想了解更多信息。2. 过去分词用在使役动词have/get和make的后面作宾语补足语。(1)“have/get+宾语+过去分词”表示“让别人做某事”。He wants to have/get his eyes examined tomorrow.(2)在“make+宾语+过去分词”这种结构中,过去分词表示结果。They managed to make themselves understood by using very simple English.3. 过去分词用在感官动词see,hear,notice,observe,watch,feel,find等之后做宾语补足语。When we saw the road blocked with snow, we decided to spend the holiday at home.We can hear the windows knocked by the heavy rain drops.带有宾语补足语的一般句型为:某些及物动词(如make等)+直接宾语(名词或代词)+宾语补足语Everyone calls him(O)(OC)(S)(V)Tom.Q1:What is the Object Complement 宾语补足语一般放在宾语_________, 对宾语起____________的作用。之后补充说明He found his new bike______.(steal)stolen过去分词作宾语补足语,表示______ 或______ 的意义,有时候两者兼而有之。被动完成小结:Step2 : Presentation用在表示状态的 keep, leave 等的后面:They kept the door ________(lock) for a long time.Don’t leave the windows ________(break)like this all the time.2. 用在感官动词watch, notice, see, hear, feel, find, listen to等的后面。We can hear the windows ________(beat )by the rain drops.When we got to school, we found the door________ (lock).用法:lockedbrokenbeatenlocked3.用在wish, want, like, expect, order等表示愿望,希望,命令这一类动词后面.The teacher would not like the problem _____________(discuss) at the moment.I want the dress _________(make) to my own measure.4. 用在使役动词have, make,get,keep 的后面.1)have sb/sth done “请别人做某事”They had many trees __________(plant).He had his leg ___________(break) in the accident.I had my wallet ___________(steal) in the bus.discussedmadeplantedbrokenstolenwith的复合结构:He said goodbye to us with tears in his eyes.用在 “with/without+宾语+宾补” 这一结构中,过去分词与宾语之间是动宾关系.The thief was brought in, with his hands__________(tie) behind his back.With many flowers ____________(plant) around the building, his house looks like a beautiful garden.tiedplanted注意:I saw him ________(get) off the bus.I saw him ________(knock) down by a car.I saw him ________(lie) on the road just now.(to) do: 整个过程V-ed:被动V-ing:主动,正在进行V-ed、V-ing与 to do作 OC 的区别:getknockedlyingJohn received an invitation to dinner, and with his work __________(finish), he gladly accepted it.2. ---Did Peter fix the computer himself ---He had it _______(fix), because he doesn’t know much about computers.3.I was wondering why they kept the door ________ (lock) for such a long time.finishedfixedlockedStep3:Practice4.This is the first time that I have heard the poem _______ (speak) in English.5.
