Conversation Two
M: How do you and your housemates like [22]the new co-op? I'm thinking of joining it myself.
W: We like it quite a bit. We get some very fresh produce and staples and fair prices.
M: Does it save time?
W: Unfortunately, the answer is no. The co-op doesn't carry everything. So we still wind up going to the supermarkets too, for cleaning supplies, batteries, that sort of thing.
M: I wish the co-op sold those items.
W: Well, I've been talking about it with some of the other members.
M: What do members have to do? Just pay a membership fee?
W: Yeah. There's a fee and there're meetings. But attendance isn't acquired. [23]But we do have to work there for an hour every week, which isn't too bad. Once you are there you can get your shopping done.
M: I wouldn't mind working there for some time. You'll get to know about the products. [24]But is the food free of additives? That will be the main reason I join. I'm a convert from junk food. Until now my diets have been largely chemical additives and pesticides.
W: Well, a lot of food is pure and pesticide-free. They also have vitamin supplements and soy and tofu and that kind of thing. Lots of health food enthusiasts shop there. So if any source is health oriented, the co-op is.
M: I'd like to try it just for a month or so. Do they have trial memberships?
W: The shortest membership time is one month. Then if you like it, you can join for longer periods. And it becomes cheaper. [25]A six-month membership costs as much as five individual months.
M: Sounds pretty easy. Maybe next time I run into you again it'll be at the checkout line in the co-op.

Questions 22 to 25 are based on the conversation you have just heard.
22. What are the speakers mainly discussing?
正确答案：A
解析：对话开门见山地提到对消费合作社的看法，然后围绕这个话题展开讨论，谈到这个合作社的好处和不足，以及入社要求和费用。男士第一句就说：“你和你同屋的人对于那个合作社看法如何？我也考虑加入。”直接进入话题，故A正确。选项为名词短语，通常问主旨。主旨题的答案特征为含核心词、具概括性。虽然没有选项A中的food一词，不过后面录音中“fresh produce and staples”以及“food free of additives”说明了这个合作社是关于食品消费的。
23. What do the members of the co-op have to do?
正确答案：D
解析：男士问“成员需要做些什么”，女士回答：“我们每周必须在那里工作一个小时。”故答案是D。四个选项都是动词原形，一般这种题目问建议、打算或将要做的事。听到什么选什么。
24. What is the purpose for the man to join the co-op?
正确答案：B
解析：男士说“不过那里的食品是不是都没有添加剂啊？这是我要加入的主要原因。”和B符合。四个选项都是动词不定式结构，多表示目的、打算或将来的动作。根据选项内容可以判断题目询问做某事情的目的，尤其选项C中含有his，说明询问男士做事情的目的。听到什么选什么。
25. What will benefit the people who join the co-op for a six-month period?
正确答案：C
解析：女士说：“6个月的会员费只相当于5个单月的费用。”言下之意，费用会比单月付要低，故C正确。
