GRAMMAR(2) used to和would的用法 [教材示例] 分析下列教材中的句子，写出并体会它们的语法功能 1．Advertising agencies would create a basic type of advertisement known as a commercial advertisement. 2．Classic advertisements used to give information about finding certain products. 3．From the name you would know what the company sells，where they are located，and the name of the product. 4．Advertising agencies used to create this kind of advertising and it could be very effective. 5．Ideas that would work in the past genuinely are not as effective now. [探究发现] used to和would均为情态动词，其后跟动词原形作谓语，used to表示过去的习惯动作或状态，暗含现在已不存在，而would表示过去的“意志、意愿”。 考点1　used to与would的共同之处 1．used to与would都可用来表示过去经常性或习惯性的动作，常常可以换用。 He used to/would spend his spare time reading books. 过去，他常常把空闲时间用在读书上。 2．used to与would都不能用来表示动作发生的具体频度或具体的一段时间。 I used to/would go to France six times.(×) I went to France six times.(√) 我去过法国六次。 He used to/would live in Africa for twenty years.(×) He lived in Africa for twenty years.(√) 他在非洲住了二十年。 ◎巧学活用1——补全句子 ①We used to/would walk to school(常步行去上学) every day when we were young. 学生用书第98页 ②Mother used to/would tell us stories(常给我们讲故事) at bedtime when we were children. 考点2　used to与would的区别 1．used to可表示过去的习惯动作或状态，而would只表示过去的习惯动作。 When we were boys we used to/would go swimming every summer. 小时候，每到夏天我们都要去游泳。 He is not what he used to be. 他已非昔日的他了。(不能用would) 2．used to表示过去经常性或习惯性的动作或状态，现在已经结束；would则表示有可能再发生。 People used to believe that the earth was flat. 过去，人们总以为地球是扁平的。(现在已不再这样认为) He would go to the park as soon as he was free. 过去，他一有空就去公园。(现在有可能还去) 3．would表示反复发生的动作。如果某一动作没有反复性，就不能用would，只能用used to。 And from that day on，as soon as the table was cleared and the dishes were removed，mother would disappear into her sewing room to practise. 从那天起，只要碗盘撤掉，饭桌一清理干净，妈妈就马上躲进做针线活的房间练习起来。(具有反复性) I used to live in Beijing. 我过去住在北京。(没有反复性) 名师点津 used to的否定、疑问式和附加疑问句 基本形式 used to 否定式 used not/usedn't to do/didn’t use to 疑问式 Used sb to do sth？ Did sb use to do sth？ 反意疑问式 usedn’t/didn't＋主语/there He didn’t use to drive to w
