語(yǔ)法精華陳述句改特殊疑問(wèn)句的方法：四步法在一般疑問(wèn)句的基礎(chǔ)上，句首添加一個(gè)疑問(wèn)詞即可，可根據(jù)劃線(xiàn)部分確定是什么疑問(wèn)詞。(常用的疑問(wèn)詞有：what什么，who誰(shuí)，whose誰(shuí)的，which哪個(gè)，when何時(shí)，where哪里，how怎樣，why為什么等。)接著找be動(dòng)詞或can，shall，will等放在疑問(wèn)詞后面，若沒(méi)有則請(qǐng)助動(dòng)詞do/does/did幫忙，寫(xiě)在疑問(wèn)詞后面，howmany除外，必須先寫(xiě)物品，再寫(xiě)be動(dòng)詞等（老師課堂上可舉例講解）。和how有關(guān)的疑問(wèn)詞：howmany,howmuch,howold,howlong,howoften,howfar等。3.劃線(xiàn)部分去掉后剩下的內(nèi)容照抄，（some改成any，第一人稱(chēng)改為第二人稱(chēng)）4.句點(diǎn)改成問(wèn)號(hào)。快速搶答練習(xí)：IwillmakemodelplaneswithmyclassmatesonSunday.(對(duì)畫(huà)線(xiàn)部分提問(wèn)）JimisgoodatEnglishandMaths.（對(duì)畫(huà)線(xiàn)部分提問(wèn)）SuYangisaskingBensomequestions.（對(duì)畫(huà)線(xiàn)部分提問(wèn)）4.WangBingisheavierthanGaoShan.（對(duì)畫(huà)線(xiàn)部分提問(wèn)）5.Igettotheshoppingcenterbybus.（對(duì)畫(huà)線(xiàn)部分提問(wèn)）6.IwasborninBeijingin1981.（對(duì)畫(huà)線(xiàn)部分提問(wèn)）7.Emmaboughtonedictionaryyesterday.（對(duì)畫(huà)線(xiàn)部分提問(wèn)）8.IttookmehalfanhourtogotothePeople’sSquarebysubway.（對(duì)畫(huà)線(xiàn)部分提問(wèn)）9.It’sabout5kilometersfrommyhometoschool.（對(duì)畫(huà)線(xiàn)部分提
