高二英語unit17 disabilities知識點總復習教案
section i 課前準備、聽力、口語
1. talk about disability? 談一談殘疾 (p. 49 goal 1)
* disability和inability
▲ dis-和in-都是表示否定意義的前綴，但用在ability前，表示不同的意思，disability意為“殘疾”，而inability意為“無能力”“沒辦法”。請比較下列例句，注意這兩個詞的不同意思。① i was surprised at her inability to do things promptly. 她不能迅速處事，我感到驚異。② she is deaf，but refuses to let her disability prevent her from doing what she wants to do. 她失聰，但她不讓自己的殘疾妨礙自己去做想做的事。③ his inability to pay his debts made his parents worried. 他無力償還債務使他父母親很著急。④ her lack of experience is a severe disability. 她缺少經驗是一個嚴重的障礙。
【注】ability的形容詞是able，其前也有兩個否定前綴，dis-和an-表示不同的意思，disable是動詞，意為“使……傷殘”，而unable則是形容詞，表示“不能的”“不會的”。如：① that illness disabled him and left him unable to work. 那病使他殘疾，不能工作。② an accident disabled him from teaching. 一次交通事故使他再也不能教書了。③ he seems unable to understand the simplest instructions. 他看來似乎連最簡單的說明也不懂。④ he was unable to sleep at night because of his anxiety. 他因焦慮而晚上睡不著。
2. imagine what difficulties and dangers you might face. 想像一下你可能面對的困難和危險。(p.49 warming up ex.1) ▲ imagine
(1) vt. imagine + 名詞/代詞/動名詞/從句 ① can you imagine a fat man like that climbing? 你能想像得出那樣胖的人爬山嗎? ② i can't imagine asking him for money. 我難以想像向他開口要錢。
注意：imagine不接不定式。只接動名詞 ① it's hard to imagine a greater threat to world peace. 難以想像還有對世界和平更大的威脅。② you can't imagine how i missed the bird. 你想像不到我是多么想念那只鳥。
注意：imagine sb. to be結構，但不能說imagine sb. to do. 如: you imagine yourself (to be) in the place. 設想你處在這個位子上。
(×) i can’t imagine you to do anything worse.
(√ ) i can’t imagine you doing anything worse.
我難以想像你還能做更差的事。
(2) imagine可用于雙重問句形式，其結構為特殊疑問句，imagine部分為插入部分，類似動詞還有think, believe, suggest, suppose, guess等。① what do you think his explanation is? 你認為他的解釋是什么? ② which mouse do you imagine we should pick out? 你認為我們該挑哪種鼠標?
注意：該句型為特殊疑問句形式，所以回答時應用特殊疑問句的回答形式。-- how much do you think this car cost? 這車你認為值多少錢? -- i think it costs 4, 000 dollars. 我認為值4 000美元。
注意：此類動詞反問句的構成有兩種情況：當主句主語是第一人稱時，反問根據從句；當主句主語為二、三人稱時根據主句。① i think she is the best student in our class, isn't she? 我認為她是我們班最好的學生，不是嗎? ② she thinks that he should have finished his work, doesn't she? 她認為他已完成了工作，是嗎?
