　　高二英语unit17 disabilities知识点总复习教案
　　section i 课前准备、听力、口语
　　1. talk about disability? 谈一谈残疾 (p. 49 goal 1)
　　* disability和inability
　　dis-和in-都是表示否定意义的前缀，但用在ability前，表示不同的意思，disability意为＂残疾＂，而inability意为＂无能力＂＂没办法＂。请比较下列例句，注意这两个词的不同意思。① i was surprised at her inability to do things promptly. 她不能迅速处事，我感到惊异。② she is deaf，but refuses to let her disability prevent her from doing what she wants to do. 她失聪，但她不让自己的残疾妨碍自己去做想做的事。③ his inability to pay his debts made his parents worried. 他无力偿还债务使他父母亲很着急。④ her lack of experience is a severe disability. 她缺少经验是一个严重的障碍。
　　【注】ability的形容词是able，其前也有两个否定前缀，dis-和an-表示不同的意思，disable是动词，意为＂使……伤残＂，而unable则是形容词，表示＂不能的＂＂不会的＂。如：① that illness disabled him and left him unable to work. 那病使他残疾，不能工作。② an accident disabled him from teaching. 一次交通事故使他再也不能教书了。③ he seems unable to understand the simplest instructions. 他看来似乎连最简单的说明也不懂。④ he was unable to sleep at night because of his anxiety. 他因焦虑而晚上睡不着。
　　2. imagine what difficulties and dangers you might face. 想像一下你可能面对的困难和危险。(p.49 warming up ex.1)   imagine
　　(1) vt. imagine + 名词／代词／动名词／从句 ① can you imagine a fat man like that climbing? 你能想像得出那样胖的人爬山吗? ② i can＂t imagine asking him for money. 我难以想像向他开口要钱。
　　注意：imagine不接不定式。只接动名词 ① it＂s hard to imagine a greater threat to world peace. 难以想像还有对世界和平更大的威胁。② you can＂t imagine how i missed the bird. 你想像不到我是多么想念那只鸟。
　　注意：imagine sb. to be结构，但不能说imagine sb. to do. 如: you imagine yourself (to be) in the place. 设想你处在这个位子上。
　　( ) i can’t imagine you to do anything worse.
　　(  ) i can’t imagine you doing anything worse.
　　我难以想像你还能做更差的事。
　　(2) imagine可用于双重问句形式，其结构为特殊疑问句，imagine部分为插入部分，类似动词还有think, believe, suggest, suppose, guess等。① what do you think his explanation is? 你认为他的解释是什么? ② which mouse do you imagine we should pick out? 你认为我们该挑哪种鼠标?
　　注意：该句型为特殊疑问句形式，所以回答时应用特殊疑问句的回答形式。-- how much do you think this car cost? 这车你认为值多少钱? -- i think it costs 4, 000 dollars. 我认为值4 000美元。
　　注意：此类动词反问句的构成有两种情况：当主句主语是第一人称时，反问根据从句；当主句主语为二、三人称时根据主句。① i think she is the best student in our class, isn＂t she? 我认为她是我们班最好的学生，不是吗? ② she thinks that he should have finished his work, doesn＂t she? 她认为他已完成了工作，是吗?
　　(3) imagine，believe，suppose，think等词在构成否定句时一般要否定前移，同时注意这些词的肯定、否定答复。① i don＂t think he will be the likeliest candidate for the manager of human resource department. 我认为他将不是人力资源部经理最可能的人选。② i don＂t think that he did the best. 我认为他并非最好。③ --do you think tom is the best student in our class? 你认为汤姆在我们班上是最好的学生吗? -- yes, i think so. (肯定答复)是，我认为是。-- no, i think not / i don＂t think so. (否定回答)不，我认为不是。

　　情态动词might表推测＂可能＂，另外表推测的情态动词还有must，may，can，could等词，用来表示对现在情况推测时后加动词原形；对过去情况推测时后加have done形式；might可能性比must，may弱，且must只用于肯定句，can只用于否定或疑问句。① we＂d better hurry. our teacher must be waiting for us. 快点，我们老师肯定正在等我们。② you mustn＂t play with the knife. it might
　　hurt your hand. 不要玩刀子，它会割伤你的手。③ peter may come with us, but he isn＂t sure. 彼得可能会跟我们来，但他拿不定主意。④ he must have finished his homework. 他肯定已经完成作业了。⑤ he cannot have attended your lecture yesterday. i saw him in the cinema. 他昨天不可能去听你的演讲了，我在电影院看见他了。
