延续动词与瞬间动词用于完成时的区别 1. 用于完成时的区别 延续动词表示经验、经历； 瞬间动词表示行为的结果，不能与表示段的时间状语连用。 He has completed the work. 他已经完成了工作。(表结果) I''ve known him since then. 从那时开始我知道了他。(表经历) 2. 用于till / until从句的差异 延续动词用于肯定句，表示"做……直到……"； 瞬间动词用于否定句，表示"到……，才……" He didn''t come back until ten o''clock. 直到十点钟他才回来。 He slept until ten o''clock. 他睡到了十点钟。 常见考法1. 把考察放在从句中增加难度； 2. 和被动语态放在一起考察； 3. 根据状语确定时态； 4. 用现在完成时的句型。 误区提醒 1. 现在完成和一般过去弄混； 2. 现在完成时的句型不熟悉； 3. 不能根据状语选定现在完成时。 My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of clothes that wouldn’t fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautiful when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn’t get any channels showing all-night movies or I would never have gotten to bed. Then I started developing a problem with the set that involved static(静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set. When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my first, and it stopped working altogether. My trip to the repair shop cost me $62, and the sit is working well now, but I keep expecting more trouble.[来源:学#科#网Z#X#X#K] 1. Why did the author say he was fooled into buying the TV set? A. He got an older model than he had expected. B. He couldn’t return it when it was broken. C. He could have bought it at a lower price. D. He failed to find any movie shows on it. 2. Which of the following an best replace the phrase “signed off” in paragraph 1? A. ended all their programs B. provided fewer channels C. changed to commercials D. showed all-night movies 3. How did the author finally get this TV set working again? A. By shaking and hitting it B. By turning it on and off C. By switching channels D. By having it repaired 4. How does the author sound when telling the story? A. Curious B. Anxious C. Cautious D. Humorous 【解析】 1. C 细节理解题。根据第一段第四行“when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid.” 当我看到报纸上75美元比我买的价格低的时候，我感觉我上当了。故选C。 2. A 词义推测题。根据后一句Fortunately, I didn’t get any channels showing all-night movies or I would never have gotten to bed.：幸运的是，我没可整晚看电影的频道，否则就不能睡觉了，故选A。 3.D 细节理解题。根据文章最后一段的My trip to the repair shop cost me $ 62，可知作者由于用拳头砸电视，导致电视没了噪音，也什么都不出了。最后只好自己花钱去修理店修电视机，共花了62美元，故选D。 4.D推理判断题。根据开头Fortunately, I didn’t get any channels showing all-night movies or I would never have gotten to bed.意思是说：看不了电视节目就可以睡觉；中间还说I actually began to build up my arm muscles(肌肉) shaking my set.意思是：晃动电视的同时锻炼了胳膊肌肉，可知作者很诙谐幽默。故选D。
