Answer 1

【答案】

C

【解析】

試題分析：根據語境可知此句的含義我現在是走著去上學，而以前是騎自行車去上學�？疾榈氖枪潭ň湫徒Y構used to do sth表示過去常常做某事，現在不做了�，F在經常做的事情要用一般現在時，故選C。

考點：固定句型結構used to do sth的基本用法

點評：固定句型結構be used to doing sth、used to do sth 、be used as和be used for doing sth是四個容易混淆的知識點。要注意他們的區別和意義。be used to doing sth是習慣做某事，used to do sth表示過去常常做某事，現在不做了。be used as是把…用作…be used for doing sth表示被用來做某事。
