Language points1. take the subway 乘坐地铁乘坐某种交通工具去某地take + the/a + 交通工具 + to + 地点= get/go to + 某地 + by + 交通工具e.g. He often takes the subway to work. = He goes to work by subway.注意: 当home, here, there 作地点时, 不加to。e.g. Linda takes the bus home. 琳达乘公交车回家。2. Lisa: How long does it take you to get to school? 丽萨：你到学校需要用多少时间？Jane: About 15 minutes by bike. 简：骑自行车大约15分钟。1) It takes + 人 + 时间 + to do sth 是一个十分常用的句型，其中动词 take 表示“花费(时间)”。该句式的真正主语是to do sth,但为了句子平衡,故用it 作为形式主语,而把真正的主语放到后面。至于造句,一步一步按部就班,注意时态就行了。如：每天早晨浇花要花我10分钟.时态为一般现在时.It takes me 10 minutes to water the flowers every morning.做某事花费某人多长时间It takes sb. some time to do sth. e.g. It takes me ten minutes to get to school by bike. 骑车去上学花费我十分钟时间。其中“时间”可用long(长久)、a short time(短时)等来表示。另外，“人”和“所做的事情”则可视具体的上下文进行省略。例如：It doesnt take long to walk there. 走着去那儿花不了多长时间。Itll only take you a short time. 只花你一小会儿时间。2) “by + 交通工具”属固定介词短语，表示“乘坐、使用某种交通工具”。例如： by bus 乘公交车 by train 坐火车 by bike 骑自行车请注意，英语中 on foot
