17.
W: I want to go to the Chinese Vsia Office in Central. It's by the Hong Kong Park. Here it's marked on this map.
M: OK, I know where you mean.
Q: Where does the conversation most probably take place?
解析：B。女士说：“我想去中环的中国签证办公室，它在香港公园旁边，这儿，标在地图上这个位置。”（中环是香港的一个繁华地方。）表明女士是给出租车司机说明自己的目的地，故B正确。

18.
W: The weather forecast said that we would have another wonderful day tomorrow. Shall we go and climb Mount Tai?
M: Good idea. But we'd better leave very early, or else we'll get caught in the traffic.
Q: What does the man suggest?

解析：D。对于女士的建议（“我们爬泰山怎么样？”），男士说：“好的，但我们得一大早动身，否则就会遇上交通堵塞。”因此D正确。典型的“中But题”。男士在简短回答后，用But提出自己的看法，是解题要点。leave与set off 为同义表达。
