问题补充:
从北京飞往成都要花多长时间?___. 英语
答案:
【答案】 答案:How long does it take to fly to Chengdu from Beijing?表达的是客观事实用一般现在时,表示花费时间做某事用It takes sb.+时间+to do sth.这里是特殊疑问句how long多久,后加一般疑问句语序,借助于does构成一般疑问,后加原形take,故How long does it take to,fly飞,故 fly to Chengdu from Beijing,故答案是How long does it take to fly to Chengdu from Beijing?
