Conversation Two
W: Hi, Tim. Are you doing some last-minute shopping before the weekend?
M: Actually, [22]I'm looking for supplies to put together 72-hour kits for my family.
W: What's that?
M: Basically, [22]a 72-hour kit contains emergency supplies you would need to sustain yourself for three days in case of an emergency.
W: So, what do you keep in it?
M: Well, you should have enough food and water to last you three days, and you might want to pack a basic water filter in case your only water source turns out to be a pool of bug-infested water.
W: Ugh!
M: [23]As for food, you should keep it simple: food that requires little or even no preparation and that doesn't spoil.
W: That makes sense.
M: Then, you have to decide on the type of shelter you might need. [24]You might have to evacuate to a shelter, possibly with hundreds or thousands of other people.
W: That doesn't sound very fun... [24]everyone packed together like sardines in a can.
M: I always pack a sleeping bag or small, lightweight tent in the event that I have to survive on the street or in a park.
W: Wow. What about money? I have a credit card.
M: That will help. But you'd better be prepared with coins and cash, and having small bills is a must.
W: So, what do you do to communicate with other family members in case you get separated?
M: [25]I always pack two-way radios to communicate with the group. You can never depend on cell phones. Plus, you should decide on a meeting point in case your family gets separated.
W: Well, that sounds like a detailed plan.

Questions 22 to 25 are based on the conversation you have just heard.
22. What does the man want to buy?
正确答案：C
解析：第一轮对话中男士就提到了主题词72-hour kits，后来又解释说a 72-hour kit包括三天的应急供应品，故答案为C。
23. What does the man say about food?
正确答案：C
解析：根据选项可知问题与食品有关，听到As for food时注意捕捉后面的信息：关键词是little/no preparation，即C。
24. What does the woman think of an emergency shelter?
正确答案：A
解析：听到shelter时注意相关描述，关键在于理解习语packed like sardiness in a can“像罐头里的沙丁鱼”，比喻拥挤不堪。所以A正确。如果听到了男士说的“可能和成百上千的人住在一起”也可以大概猜出女士的话意。
25. What should be relied on in communication with the group according to the man?
正确答案：A
解析：四个选项都是物品，听音时要注意与对话内容匹配。男士说：“我使用无线电与团队交流，你绝不能依赖手机”。所以A正确。对话结尾常常是出题之处。
