Maybe you will be _ in it.A. interesting something; interested B. something interesting; interestingC. something interesting; interested D. something interested; interesting 【解析】形容词修饰不定代词时，应该放在其后面，可先排除A。另外，修饰某物时要用interesting，可排除D。第二空的you是人，故要用be interested in结构。答案选择C。b. 句式包：1.Mario, you used to be short, didnt you? 马里奥，你过去很矮，对吗？used to do sth 意为“过去常常做某事”，特指在过去经常发生的动作，而现在已不再发生，其中used to 可以看作情态动词，用于各种人称。【出处：21教育名师】【备课例句】He used to play soccer when he was young. 他年轻时经常踢足球。（现在不踢了）She used to be an English teacher. 她过去是一位英语老师。（现在不是英语老师了）1.其否定句为didnt use to do或used not to do，used not可缩写为usednt。【备课例句】Mr. Li didnt use to drink beer. =Mr. Li usednt to drink beer. 李先生不常喝啤酒。2.used to 的疑问句形式是“Diduse to do?”或“Usedto do”。【备课例句】Did she use to get up early?=Used he to get up early? 她过去经常早起吗？3.used to 的反意疑问句也用助动词did(nt)或used(nt)构成。【备课例句】Mario used to be late for school, didnt/usednt he? 马里奥以前上学经常迟到，对不对？【横向辐射】be used to do sth & be used to doing sth.1.be used to do sth 表示“被用于做某事”，是被动结构，强调主语是动词use的承受者。【例句】Wood can be used to make desks. 木材可用来制作书桌。Stamps can be used to send letters. 邮票可用来寄信。2.be used to doing sth意为“习惯于做某事”，其中to是介词，后须接名词或动词-ing形式。【例句】I was used to the hard life here. 我习惯这里的艰苦生活。He is used to working before six in the morning. 他已经习惯每天早晨六点以前干活。【课堂变式】1. She used to_ in the morning, but now she is used to _ at night.A. read; readB. read; readingC. reading; readD. reading; reading【解析】前一空是used to do sth结构，后一空是be used to doing 结构。若第二空采用be used to do sth结构，主语she不能成为use的承受者。另外，由but now可知前一句说的是过去的情况，后一空说的是现在的情况。正确答案是B。2. I used to go outside on weekends. (改为否定句) I_ _ to go outside on weekends.【解析】本题考查used to do的否定结构。其否定句为didnt use to do或used not to do。正确答案是didnt use/used not。2.What did his friends used to look like? 他的朋友过去长得什么样子？What does sb look like? 只用来询问某人的外貌长相，相当于What is sb like?, like在句中作介词，意为“像”。21cnjy.com【备课例句】What does Tom look like? (=What is Tom like?) 汤姆长得什么
