---Excuse me, could you tell me _______?---Sorry, sir. I wasn’t there at that time. A．how did the accident happen B．how the accident happened C．how does the accident happen D．how the accident happens

Answer 1

B

试题分析：句意：对不起，你能告诉我事故怎样发生的吗？对不起，先生。我那时不在场。在宾语从句中只能使用陈述句语序，不能使用疑问句语序。由I wasn’t there at that time.知该用一般过去时态，所以选B。
