cellular phones have had a major impact on our lives and the way that weperform every day tasks. many of these changes are apparent, while others we maynot even be aware of.

cell phones have brought a whole new meaning to the term multitasking.twenty years ago, it was not possible to talk to the office while you were atthe grocery store picking up some necessary items. you could never have had athree-way business conference while you were fixing dinner or been able to dealwith a business client from home while caring for a sick child. cell phones haveenabled us to do various tasks all at the same time.

cell phones have also enabled families to keep in closer touch with eachother. children can contact you if they have missed their ride form soccerpractice and your spouse can call while he is stuck in traffic to let you knowthat he is going to be late for supper. teenagers are able to call to askpermission to go somewhere, and with gps features that are now available on somecell phones, you are able to check to make sure that they are where they aresuppose to be.

many of these advantages we do not even notice. have you ever arrived atthe grocery store and realized that you have forgotten your grocery list? thefirst thing you would probably do is to call home and have one of your childrenread the list off to you. in the same situation in past years, you may haveforgotten things or have had to drive all the way back home to get it. if yourcar breaks down, you automatically call for help instead of having to walk tofind a pay phone. cell phones have certainly made our lives much moreconvenient.

cell phones have also changed the way that people interact with each other.when we call someone, we are actually calling the person and not a place. thisenables us to be more spontaneous when making plans as you rarely get a busysignal and unlike a land line telephone, someone is always home. cell phonesalso enable us to call if we are going to be late for an appointment, althoughthis has led to cell phone users running late more often than those who do nothave cell phones. these users seem to have adopted the attitude that appointmenttimes are not concrete and use their cell phones to renegotiate their arrivaltime.

one of the greatest disadvantages of the cellular phone is the fact that wedo not talk to strangers when traveling anymore. in the past, several peoplewaiting for a bus would engage in a conversation while they were waiting. peoplewho traveled the same routes every day might develop friendships along the way.this situation does not happen anymore. today when people are waiting for a bus,they just pull out their cell phones and speak with old friends, missing out onthe opportunity to make new ones. in large cities, many people do not know theirneighbors, even though they may have lived in the same neighborhood for years.as a society, we are beginning to lose the face-to-face contact that was such animportant part of our lives in the past.

cell phones are a great asset in aiding in our every day lives. you shouldremember, however, to hang up every once in a while and pay attention to theworld around you.

智能手机为我们的生活提供了便利，既然它做出了这么大的贡献，那我就为大家介绍一下手机的特点以及功能和保养方法。

什么是智能手机，说通俗一点就是一个简单的“1+1=”的公式，“掌上电脑+手机=智能手机”。

从广义上说，智能手机除了具备手机的通话功能外，还具备了pda的大部分功能，特别是个人信息管理以及基于无线数据通信的浏览器和电子邮件功能。智能手机为用户提供了足够的屏幕尺寸和带宽，既方便随身携带，又为软件运行和内容服务提供了广阔的舞台，很多增值业务可以就此展开，如：股票、新闻、天气、交通等等。

这些就是大多智能手机所具备的共同特点。

那么智能手机还具备什么功能呢?智能手机这个说法主要是针对“功能手机”而来的，本身并不意味着这个手机有多“智能”;从另一个角度来讲，所谓的“智能手机”就是一台可以随意安装和卸载应用软件的“小电脑”。

经过整理分析调查的资料，我发现智能手机的功能有一下几点：都可以进行正常通话、发短信等手机自带应用;

可以连接无限网;可以浏览网页和多媒体应用;具有人性化，可以根据个人需求扩展机器功能;

具有开放性;功能强大，第三方软件支持多。

对于智能手机，只知道特点和功能是不行的，我们必须要清楚智能手机的保养方法。首先要注意存放方式，要让手机远离磁铁环境，注意使用环境，保护好外壳。其次对于电池要把握好充电的时间，谨慎选择充电器，充电不能过于频繁。

看了以上智能手机的介绍，相信你对智能手机已经有了一定的了解。我们要正确利用手机的益处为我们的生活提供便利。
