Question

Bikes ______ in the 1880s and they ______ traveling around.

A．were invented; were used as

B．were invented; are used for

C．was invented; was used for

D．invented; are used to

Answer 1

B

考查被動語態。句意“自行車是在十九世紀八十年代發明的，它們被用來進行旅游觀光。”bike和invent之間是被動關系，故用被動語態，排除D；主語是復數，排除C；be used as“被用作......”；be used for doing sth.“被用來做某事”。故選B。
