Question

【题目】When did the lecture probably begin?

A. At 8:15. B. At 8:50. C. At 8:05.

Answer 1

【答案】B

【解析】听力原文：

M: When did you have your lecture yesterday?

W: It should have begun at 8:15 but it didn't start until Professor Brown came at 8:50.

对话中提到讲座本应该在8：15开始，但是布朗教授8：50还到，所以讲座8：50才开始。因此正确答案为B。
