Answer 1

【答案】

C

【解析】

试题分析：根据语境可知此句的含义我现在是走着去上学，而以前是骑自行车去上学。考查的是固定句型结构used to do sth表示过去常常做某事，现在不做了。现在经常做的事情要用一般现在时，故选C。

考点：固定句型结构used to do sth的基本用法

点评：固定句型结构be used to doing sth、used to do sth 、be used as和be used for doing sth是四个容易混淆的知识点。要注意他们的区别和意义。be used to doing sth是习惯做某事，used to do sth表示过去常常做某事，现在不做了。be used as是把…用作…be used for doing sth表示被用来做某事。
