Mario, you used to be short, didnt you? 马里奥,你以前个子很矮,是吗?【解读1】这是一个反意疑问句。反意疑问句是表示说话人对所陈述的事情有所怀疑或不肯定,需要询问对方的看法。反意疑问句由“陈述句 + 附加疑问句”构成,若陈述句为肯定形式,则附加疑问句要用否定形式;若陈述句为否定形式,则附加疑问句要用肯定形式,即“前肯后否;前否后肯”。同时,前后两部分的人称、数、时态等都要保持一致。附加疑问句一般由“助动词、be动词或情态动词的肯定形式或否定形式 + 人称代词”构成,且否定形式常用缩写形式。 注意:当陈述句中含有no, never, seldom, hardly, little, few, nothing, nobody等表示否定意义的词时,附加疑问句要用肯定形式。当陈述句中含有unhappy, dislike, unfriendly等带否定前缀的派生词时,当作肯定句处理,附加疑问句要用否定形式。【举例】(1) You saw him yesterday, didnt you? 你昨天看见过他,是吗? (2) This is a beautiful picture, isnt it? 这是一幅美丽的图画,是吗?(3) Lucy cant play the piano, can she? 露西不会弹钢琴,是吗?(4) There is little food at home, is there? 在家里几乎没有食物,是吧?(5) He looks unhappy, doesnt he? 他看上去不高兴,是吧? 【练习】把下列句子补充完整(1) They work hard, _ they?(2) You didnt go, _ you?(3) There are few apples in the basket, _ there?(4) He can hardly swim, _ he?(5) The girl dislikes history, _ she?【解读2】(1)used to do sth.意为“过去常常做某事”。其中,used to是一个情态动词,用于过去持续或经常发生的事,意为“曾经”,只用于过去时态。当used to用于反意疑问句中时,附加疑问句部分通常用didnt / usednt + 人称代词的主格。其否定形式通常为didnt use to, 它的另一种否定形式used not to(简写成usednt to)是一种相当正式的用法。构成疑问句时,常用did, 即Did sb./ sth. use to?而另一种疑问句结构Used sb./ sth. to?是一种过时且非常正式的用法,通常作书面语。(2)used to do sth., be /get used to (doing) sth. 与be used to do sth. /for (doing) sth.的辨析。used to do sth.意为“过去常常做某事”。其中,used to是一个情态动词He used to go to our school.他曾在我们学校就读。be /get used to (doing) sth.意为“习惯于(做)某事”。其中,used是形容词,I am /get used to getting up early every day. 我习惯每天早起be used to do sth. /for (doing) sth.意为“被用来做某事”。其中,used 是动词use的过去分词The knife is used to cut things. /The knife is used for cutting things。刀被用来切东西。【举例】(6) He used to play here, didnt / usednt he? 他过去常常在这里玩,是吗?(7) She didnt use / usednt to listen to music. 她过去不常听音乐。(8) Did you use / Used you to go to church?你以前经常去教堂吗? 【练习】单项选择。(6) Her son _ coke, but now he _ milk.A. used to drink; is used to drinkingB. used to drinking; drinks C. is used to drinking; used to drinkD. is used to drink; is drinking(7)补全句子。Bob used to wear glasses, _ _?6EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F3756EDBC3191F2351DD815FF33D4435F375
