A. think; won’t come B. don’t think; come C. don’t think; will come D. think; come 析:根据否定转移的原则,前半部分应用I don’t think, tomorrow是将来时间状语,故从句应用将来时态。答案为C项。 2. 在反意疑问句中 当复合句的主句是I / we think (believe, suppose, expect, imagine等)时,反意疑问句(助动词/情态动词/be动词+主语)的主谓部分要和从句的主语、谓语保持一致;当主句的主语是第二、三人称时,反意疑问句的主谓部分要和主句的主语、谓语保持一致。如: ①I don’t suppose anyone will volunteer to paint such a big house, _________? A. do IB. don’t I C. will theyD. won’t they 析:这是一个反意疑问句。当主句主语是第一人称,谓语动词是think,suppose等动词时,反意问句的主谓语要根据从句的主谓语来确定。前面是否定句,所以反问部分要用肯定形式。答案为C项。 ②Mrs Black doesn’t believe her son is able to design a digital camera, __________? A. is sheB. isn’t she C. doesn’t sheD. does she 析:该句的主句谓语动词虽是believe,但主句主语不是第一人称,所以反意疑问句的主谓语应根据主句的主谓语来确定。答案为D项。 3. 特殊的宾语从句 这种特殊句型(疑问词+do you think+主语+谓语+其余部分)主要用来征询对方的意见、建议、推测等。其插入语部分的动词常用的有:think, believe, suppose, imagine, propose, say等。如: ①Mum is coming. What present _________ for your birthday? A. you expect she has got B. you expect has she got C. do you expect she has got D. do you expect has she got 答案为C项。 ②_________ be sent to work there? A. Who do you suggest B. Who do you suggest that should C. Do you suggest who should D. Do you suggest whom should 析:此题既考查了do you suggest作插入语的用法,也考查了suggest作“建议”讲时后跟的宾语从句要用虚拟语气。虽然在形式上suggest没有宾语,但在实际意义上who (should) be sent to work there作了suggest的宾语。答案为A项。 4. 宾语可替代 think, believe, suppose, imagine, expect ...等后面常常跟so或not来替代宾语从句的内容,其中so替代肯定句;not替代否定句。如: ①——The boys are not doing a good job at all, are they? ——___________. A. I guess not soB. I don’t guess C. I don’t guess soD. I guess not 析:答案为D项。为了避免重复,用not替代they are not doing a good job at all。 ②——I believe we’ve met somewhere before. ——No, __________. A. it isn’t the sameB. it can’t true C. I don’t think soD. I’d rather not 析:当不同意对方意见时,可以用I don’t think so或I think not来回答。not或so替代回答中与问句重复的部分。答案为C项。 跟踪练习: 1. ——You haven’t lost the ticket, have you? ——__________. I know it’s not easy to get another one at the moment. A. I hope notB. No, I have C. I hope soD. Yes, I’m afraid so 2. Mrs Black doesn’t believe so many people are suffering from this tsunami, _________? A. aren’t theyB. are they C. doesn’t sheD. does she 3. I don’t think he could have done such a stupid thing last night, __________. A. do IB. could he C. did heD. has he 4. ________ you have seen both fighters, _________ will win? A. Since; do you think who B. As; who you think C. When; whoever D. Since; who do you think 参考答案:1——4A D C D think的用法 A. vi.想,思考 Imagine 用法 一、表示“想象”、“设想”、“以为” 1. 可用于被动结构和系表结构。如: It can easily be imagined.这很容易想象出来。 2.可接名词作宾语。如: Imagine a railway station,a bus company or a cinema,which many people need to ring to find out the times of trains,buses or films.想象一个火车站、一个公交公司或一个电影院,许多人需要向那里打电话弄清火车、汽车班次和电影开场的时间。 3.可接V-ing作宾语,不接动词不定式作宾语。如: I didn't imagine becoming a teacher in my childhood.在童年时期,我并未想象成为一名教师。 4.可接“one's/n./pron.+V-ing”作宾语,其中one's代表形容词性的物主代词和名词所有格,与V-ing具有主谓关系。如: I can't imagine my marrying a girl of that sort.我难以想象我与那种女子结婚后的情形。 Can you imagine Tom cooking dinner for twenty people?你能想象出汤姆为20个人做饭的样子吗? 5. 可接that-clause作宾语。如: I imagine that you are tired from the journey.我料想你是由于旅行而疲劳了。 6. 可接连接副词或连接代词引导的宾语从句。如: I can't imagine why they speak against you.我想不出来为什么他们都不向着你说话。 I can't imagine what he means.我想不出他的用意。 7. 可接“n./pron.+(to be)n./adj.”作复合宾语,其中n./pron.作宾语,(to be)n./adj.作宾语补足语,to be可以省略。如: Imagine yourself(to be)a teacher.想象一下你是一位老师。 I imagined the ship(to be)very large.我想象那船很大。 8. 可接“n./pron.+as+n.”作复合宾语,其中n./pron.作宾语,as+n.作宾语补足语。如: I imagined you as a big tall man.我以为你是个高大的人。 二、表示“认为”、“想” 1. 后面接复合宾语。如: He imagined himself very rich.他认为自己很富有。 2.后面接that-clause作宾语。若 that-clause是否定意义,可用主句的否定形式表示从句的否定意义,that可省略。如: I don't imagine(that)they will come tomorrow.我认为他们明天不会来。 suppose以及be supposed to的用法 suppose的基本意思是“猜想;以为;假定”,但在具体的语言环境中意义不止于此,其用法如下: 1. suppose + that 从句,表示“猜测;假定”。如: I suppose that you are right. 我想你是对的。 You can suppose that A equals B. 你可以假定A等于B。 2. suppose +名词 / 代词 + to be...,表示“认为……是……”。如: Many people suppose him to be over 50. 许多人认为他已经50多岁了。 3. suppose用于祈使句中,表示“让……”。如: Suppose we go for a swim. (= Let's go for a swim.) 让我们去游泳吧。 be supposed to 的用法 用法一: be supposed to... 其中to是动词不定式符号,不是介词,其后要跟动词原形。当be supposed to... 的主语是“人” 时,意为“应该…… ”;“被期望……”,它可以用来表示劝告、建议、义务、责任等,相当于情态动词should。如: Everyone is supposed to wear a seat-belt in the car. 每个人在汽车里都应该系安全带。 Teachers are supposed to treat all the students alike. 老师应该对所有的学生一视同仁。 用法:当be supposed to... 的主语是“物”时,它表示“本应;本该”,用于表示“某事本应该发生而没有发生”。如: The new laws are supposed to prevent crime. 这些新法令本应该起到防止犯罪的作用。 The train was supposed to arrive half an hour ago. 火车本应在半小时之前到达。 用法三: be supposed to后面接“have + 过去分词”时,表示“本应该做某事而没做”。如: You are supposed to have handed in your homework by now. 现在你应该已经把作业交上来了。 He is supposed to have arrived an hour ago. 他应该一小时前就到了。 用法四: be supposed to... 的否定结构为be not supposed to...,它常用于口语中,意为“不被许可;不应当”。如: She was not supposed to be angry about that. 她本不该为那件事而生气的。 You are not supposed to smoke on the bus. 你不应该在公共汽车上吸烟。 一、Suppose做及物动词,意为“想,认为,猜想,料想”,用法如下: 学以致用: 1. I (suppose ) he will be back by 8 o'clock . 2. Parents are (suppose ) to teach their children how to behave well. 3.I suppose prices will go up .(否定句) Keys : 1.suppose 2. supposed 3. I don't suppose prices will go up . |
