Question 15 is based on the conversation you have just heard.

Conversation Two

W: This is Kerry Burke from New York Daily News. I’m speaking to Delroy Simmonds, an（13）unemployed Brooklyn man who missed a job interview Tuesday for the best of reasons: （12）He was saving the life of a 9-month-old boy who was blown into the path of an oncoming subway train by a high wind.

M: Everybody is making me out to be some sort of superhero. I’m just an ordinary person, and a father of two. Anybody in that situation would have done what I did.

W: You were going to an interview when the incident occurred, right?

M: Yes, I was on my way to apply for a maintenance position. I’ve been looking for a job for a year and more. I’m looking for something to support my family.

W: Tell us what happened at the station.

M: （14）There was a strong wind. It had to be 30 to 40 miles an hour. There was a woman with four kids. One was in a pushchair. The wind blew the baby onto the tracks.

W: Witnesses said people were looking on in horror as the child’s mother, identified by sources as Maria Zamara, （15）stood frozen in shock. In the distance, people could see the train rounding a bend, headed into the station. I guess you were not aware of any of these, right?

M: No. I just jumped down and grabbed the baby. The train was coming around the corner as I lifted the baby from the tracks. I really wasn’t thinking.

W: What an amazing story. Thank you very much.

15. How did the mother react when the incident occurred?

解析：A。该题目为细节题。问题是：事故发生时妈妈的反应是什么？由选项推测要听描述女士状态的内容。根据关键词“mother”定位原文出处，“as the child’s mother, identified by sources as Maria Zamara, stood frozen in shock”，孩子的妈妈Maria Zamara当时震惊地僵住了。选项A）She stood motionless in shock，与原文意思是同义替换，motionless和frozen均表示“僵住不动”。因此，此题目正确答案为A。
