Question

【题目】I regret that I waited in the queue for a long time to buy the ticket this morning. I ______ it online.

A.could buyB.must buy

C.could have boughtD.must have bought

Answer 1

【答案】C

【解析】

考查情态动词。句意：今天早上我排队等了很长时间才买下这张票，我感到很后悔。我本来可以在网上买的。could have done表示过去本来可以有机会选择做某事，但实际上没有那样做，通常译为“本来可以”。故选C。
