錄音原文：

17.
W: Hello, is that Steve? I'm stuck in a traffic jam. I'm afraid I can't make it before 7 o'clock.
M: Never mind. I'll be here waiting for you.
18.
M: You really seem to enjoy your literature class.
W: You are right. It has opened a new world for me. I'm expected to the thoughts of some of the world's best writer. I've never read so much in my life.

解析：

17. B 關鍵是要聽到 7 o'clock和waiting for you。女士說交通堵塞，恐怕7點之前趕不到男士那里了；男士說“沒關系，我會在這里等你。”很顯然，他們約好7點見面。B正確。男士說他會等待女士到來，故A,D都不正確。對話中的jam表示“交通堵塞”而不是“果醬”，make it在對話中意為“及時抵達”而不是“制作”，故C錯誤。

18. A 話題是literature class，關鍵句是never read so much"從來沒讀過這么多書"，說明A正確。B錯在written;C錯在met,對話中的be exposed to the thoughts表示“接觸思想”，而不是獨到這些人；D是利用個別原詞進行干擾。
