情景对话:
A: Which one do you want to buy?
B: I know we've been here looking for an ideal refrigerator for about an hour. I just still don't know which one is the best.
A: All right. Maybe we should focus on the latest modelsof those big brands. Now shall we go take a look at thatfridge?
B: Oh, it looks rather fashionable.
A: I wonder what refrigerant it uses. Does it use freon?
B: I don't think so. It is reported that the latest models use some other refrigerants. Freon has been deserted.
A: That's good. Wow, this refrigerator has four compartmentsseparated as freezers.
B: So we can have enough room for the storage of our foodstuff.
A: Well, you know the optimum temperature range for perishable food storage is 3 to 5 0C.
B: Yeah. That's why a refrigerator is usually designed to maintain a temperature a few degrees above the freezing point of water.
A: I guess at a temperature below the ambient temperatureof the room, the reproduction rate of bacteria can be decreased so that food can be kept fresh.
参考译文:
A:你想买哪一台?
B:我知道我们在这儿逛了快一个小时了，为的就是买台合意的冰箱。但哪台比较好我真是无法定夺。
A:行啦，我们或许应该重点看大品牌的新型号产品。我们现在过去看看那台冰箱吧!
B:哦，它样子看上去很新潮。
A:我想知道它里面的制冷剂用的是什么，会不会是氟利昂呢?
B:应该不会吧。报道都说了新生产的冰箱使用的是其他制冷剂，氟利昂已经不再使用了。
A:那就好。哇，这台冰箱有四个单独隔开的冷藏室。
B:那我们就有足够地方来存放食物了。
A:嗯，你知道吧，易变质食物的贮存温度是3-5 0C.
B:知道的，所以通常冰箱都设计好要能将温度保持在水的冰点以上几度。
A:嗯，我想温度得低于室内环境的温度，细菌的繁殖速度才会降低，食物才能保持新鲜。
