Along with rapid economic development, radios and televisions have become a common household appliance in commonfamily. Generally speaking, radios are as important as televisions to an average family. However, as the functions of televisions continually by innovation of technology for creating a perfect one, it seems that televisions have the advantage. Nevertheless, from my own perspective, there is still a market for radios, or even more advantages.

随着经济的快速发展，收音机和电视在普通家庭中已经成为很普遍的家用电器。一般来说，在普遍家庭中收音机和电视一样重要。然而，由于技术的不断创新，电视的功能越来越完善，似乎电视处于优势。然而，从我的角度来看，收音机仍然是有市场的，甚至更有优势。

 On the one hand, radio gained popularity because of its low price mul-information. In common family, radio basically is used for killing time so it is perfect that the price per set is just a few dozen Yuan and takes up little space. Besides, we can gain information from the radio whenever we want. If we want to listen in to the music, news and broadcast, we just need to turn on the switch. As for television set, however, in poor, there are still some people who can't afford to buy it. If we have a television, that means we have to pay the cable bills, electricity fare. Therefore, radios are much cheaper than televisions.

一方面，收音机之所以很受欢迎的原因是因为其价格低，信息多。在普通家庭，收音机基本上是用于消磨时间，所以每台收音机的价格仅几十元，占用空间也小是刚刚好的。此外，我们也可以随时随地得到我们想要的信息。如果我们要听音乐，看新闻，听广播，我们只需要把开关打开。然而，在一些贫困地区电视对于有些人来说仍然是买不起的。如果我们有一台电视，这意味着我们要付有线电视费。所以，收音机比电视更便宜。

 On the other hand, radios are in beautiful shape and artful design. Nowadays, radios are designed to be smaller and smaller so that it can be quite convenient to take easily. For example, we can put it in our pocket and listen to it anywhere. On the contrary, televisions are too heavy and big to carry them with us. If we want to watch TV, we have to stay at home and sit in front of the TV set. Meanwhile, we can do other things while listening to the radio. However, once we watch TV, we may be addicted to it.

另一方面，收音机是外形美观小巧。如今，收音机设计得越来越小了，所以它也越来越容易方便携带。例如，我们可以把它放在口袋里，在什么地方都可以听。相反，如果带在身上的话，电视就太重太大了。如果我们想看电视，我们只能呆在家里，坐在电视机前。同时，我们可以一边听收音机一边做其他事情。然而，我们看电视的时候，我们可能会沉迷于它。

In all, radios' cost-effective is one of the reasons for the demands of buyers. An intelligent and rational consumer is the one who spends the money wisely. If you just want to have entertainment, it could be a good choice to have a radio.

总之，收音机的成本效益是买家需求的一个原因。一个理性的消费者，是会理性消费的。如果你只是想娱乐，收音机会是一个很好的选择。
