A. think; won’t come B. don’t think; come C. don’t think; will come D. think; come 析:根據(jù)否定轉(zhuǎn)移的原則,前半部分應(yīng)用I don’t think, tomorrow是將來時間狀語,,故從句應(yīng)用將來時態(tài),。答案為C項。 2. 在反意疑問句中 當(dāng)復(fù)合句的主句是I / we think (believe, suppose, expect, imagine等)時,,反意疑問句(助動詞/情態(tài)動詞/be動詞+主語)的主謂部分要和從句的主語,、謂語保持一致;當(dāng)主句的主語是第二,、三人稱時,,反意疑問句的主謂部分要和主句的主語、謂語保持一致,。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:這是一個反意疑問句,。當(dāng)主句主語是第一人稱,,謂語動詞是think,,suppose等動詞時,反意問句的主謂語要根據(jù)從句的主謂語來確定,。前面是否定句,,所以反問部分要用肯定形式。答案為C項,。 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:該句的主句謂語動詞雖是believe,,但主句主語不是第一人稱,所以反意疑問句的主謂語應(yīng)根據(jù)主句的主謂語來確定,。答案為D項,。 3. 特殊的賓語從句 這種特殊句型(疑問詞+do you think+主語+謂語+其余部分)主要用來征詢對方的意見,、建議、推測等,。其插入語部分的動詞常用的有:think, believe, suppose, imagine, propose, say等,。如: ①M(fèi)um 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 答案為C項。 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:此題既考查了do you suggest作插入語的用法,,也考查了suggest作“建議”講時后跟的賓語從句要用虛擬語氣,。雖然在形式上suggest沒有賓語,但在實際意義上who (should) be sent to work there作了suggest的賓語,。答案為A項,。 4. 賓語可替代 think, believe, suppose, imagine, expect ...等后面常常跟so或not來替代賓語從句的內(nèi)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:答案為D項。為了避免重復(fù),,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:當(dāng)不同意對方意見時,可以用I don’t think so或I think not來回答,。not或so替代回答中與問句重復(fù)的部分,。答案為C項。 跟蹤練習(xí): 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.
