录音原文：
17.W: John, are you doing research for Professor William this semester?
M: Actually, I'm working as his teaching assistant.
18.M: I heard there're a few seats left for the show tonight.
W: Really? I was under theimpressionthat the tickets were sold out a long time ago.
答案解析：
17. C 关键是要听到actually后面的话“我整做他的助教呢。”teaching assistant的职责就是assist...with his teaching，C是男士原话的同义表达，故为答案。选项A,B,D均是用research和assist及其派生词来进行干扰。
18. A 关键是要听到really后面的话“我以为票早就被卖光了。” there were no tickets left就是tickets were sold out的同义表达，故选A。sell out 表示“卖完，卖光”。对话中的left是动词leave的过去分词，意思是“剩下”，而并非形容词“左边的”，选项B即是用left“左边的”一次来进行干扰；选项C利用了a long time ago进行干扰，而选项D利用impression的派生词进行干扰，但实际上它们的内容与对话无关。
