Question

Now Nancy goes to school by bike but she________ to school in her father’s car. She says she can do some small things like this to help cut down pollution.

A.is used to going B.used to go C.is used to go

Answer

B

【解析】

句意：现在南希骑自行车上学，但她过去常乘坐她父亲的车上学。 她说她可以做一些像这样的小事来帮助减少污染。

考查一般过去时。is used to going习惯于去；used to go过去常去；is used to go被用来去。根据句中but可知，前后转折，即：南希现在骑车上学，但是过去常常坐车上学；used to do sth.表示过去常常做某事。故选B。
