Question

When I was a student, I ______ to school ______ the bus

A．used to going , by

B．used to go , on

C．used to go, by

D．was used to go, on

Answer 1

B

試題分析：句意：當(dāng)我上中學(xué)時，我常常做公交車去上學(xué)。Used to do sth意為“過去常常做某事，現(xiàn)在已經(jīng)不做了”；on the bus意為“在公交車上，通過公交車”，用介詞短語by bus時，中間不用冠詞；故選B。
