下面小编跟大家分享英语口语对话：关于买自行车的建议，希望对大家的学习的有所帮助。
L: I'm planning to buy a bicycle. As you are quite a cycling enthusiast, I wish you might give me some advice.
J: With pleasure, chap. But before I start, I need to know what you want a bike for?
L: My purpose are two-fold. On the one hand, I've grown bored of commuting on suffocating buses every day and decided to ride to work. On the other hand, bicycling is a sport, and I intend to build up my body through constantly taking a ride over the weekends.
J: Cycling during weekends? Do you mean riding to the mountainous countryside or just the neighboring towns?
L: Does that make any difference?
J: Can't be greater. If you ride on bumpy, hilly roads, a mountain bike is what you need. But if you just ride comfortably along the city lanes, you might choose a road bike.
L: Are you designed differently?
J: A road bike features skinny tires and a lightweight frame. Its riding position puts you bent over the handlebars. It's not particularly beefy in construction, and generally, it won't stand up well under heavy loads or on really rough surfaces. In contrast, mountain bikes have wide tires and a stout frame. You sit higher on them and don't have to be hunched over.

我在琢磨买辆自行车。你是位自行车爱好者。能给我点建议吗？
没问题！我得先问问，你要自行车做什么用？
有两方面原因，首先每天上下班挤公交车实在烦人，所以想改骑车。第二，骑车是运动，周末骑车逛逛总可以锻炼锻炼身体嘛。
周末骑车？骑车去哪儿？是乡下去还是只是在附近的小镇上转悠？
这有关系吗？
关系很大呢。如果你在凹凸不平的山路上骑，就要选用山地车。如果只是在城市公路上骑，还是选用平地车。
这两种车的设计不同？
平地车的轮胎比较细，架子也比较轻，骑上去，你必须蜷曲俯卧在车把上。平地车也不够结实，载重量不可以太大，也难以胜任不平发热路面。相比之下，山地车轮胎较粗，架子结实厚重，骑在上面，就不必弯着背。
