Mobile Phone

Thirty year ago almost nobody had a cell phone. Nowadays it seems everybody has one, from the youngest to the oldest.

Cell phones can be useful for a number of reasons. Firstly, they allow  us to communicate quickly in almost and situation.

This can be really useful in emergencies, and they have many other uses, such as listening to music, playing games and taking photos.

However cell phones have disadvantages  ,too. It can be very annoying when  someone is speaking loudly on their phones in a public place.

In Japan you are not allowed to make calls while on the subway for this reason .

Also, it hurts relationships when friends spend their time together texting others or answering calls on their cell phones.

so I often end up spending a lot of money.

READING FOR FUN

Probably no means of communication has revolutionized the daily lives of ordinary people more than the telephone.

大概没有一种通讯手段比电话更彻底地改变了普通人的日常生活。

Simply described, it is a system which converts sound, specifically the human voice, to electrical impulses of various frequencies, and then back to a tone that sounds like the original voice.

简单地说，这是一个系统，它可以把声音，特别是人类的声音，转换成各种频率的电脉冲，然后回到一个听起来像原始声音的音调。

In 1831, Englishman Michael Faraday(1791 - 1867) proved that vibrations of metal could be converted to electrical impulses.

1831年，英国人迈克尔·法拉第（1791-1867）证明金属的振动可以转化为电脉冲。

This was the technological basis of the telephone, but no one actually used this system to transmit sound until 1861.

这是电话的技术基础，但直到1861年才有人使用这个系统来传送声音。

In that year, Johann Philip Reis(1834 - 1874) from Germany is said to have built a simple apparatus that changed sound to electricity and back again to sound.

在那一年，来自德国的约翰·菲利普·里斯(1834 - 1874)据说制造了一种简单的仪器，可以把声音变成电，然后再变成声音。

A crude device, it was incapable of transmitting most frequencies, and it was never fully developed.

它是一种粗糙的装置，无法传输大多数频率，而且从未得到充分的发展。
