Unit 3 How do you get to school?1.短语归纳2.典句必背3.用法集萃(1)怎样表达出行方式：How do you get to school?❖描述出行方式时，通常会有如下几种形式注意：当交通工具的名词（如：bike, bus, train, car等）和by搭配时，它们前面不必加冠词；但当它们和on或in搭配时，它们之间要加冠词。
(2)基数词的表达法：基数词，表示数目或者数量的多少①one 到twelve，拼写和读音没有什么相似之处，无规律可言，应逐一进行记忆。
②thirteen到nineteen，表示“十几”，在个位数后加后缀-teen，读作/ti:n/。
注意thirteen, fifteen和eighteen的拼写。
③twenty到ninety，表示“几十”，以-ty结尾，但需注意下面几个词的拼写：twenty, thirty, forty, fifty, eighty。
④21~29直到91~99，表示“几十几”，用整十位加个位数表示，中间用连字符“-”把十位数与个位数连接起来。
例：21→twenty-one；35→thirty-five⑤one hundred意为“一百”，表示一百还可以用 a hundred。
要表示200~900，用“具体数字＋hundred”。
⑥例：200 →two hundred；900→ nine hundred注意：❖hundred前面若有具体的数词，则要用hundred的单数形式，而且其后不能跟of，此时表达确切的数字概念。
例：There are two hundred people in the square. 广场上有两百人❖hundreds of表示“数以百计的”，此时表达模糊的数字概念。
如：There are hundreds of people in the square. 广场上有好几百人(3)How far is it from your home to school?❖from ... to ... 意为“从...到...”，表示“由一点到另一点”，可用于时间、地点、数目等。
