We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology，more and more features are being added to the mobile phones which make them more useful. In addition to making calls，mobile phones also support a wide variety of other services such as text messaging，email，Internet access，business applications，gaming and photography. We can bring them everywhere，and can be reached by others anytime. They make the world smaller，bringing people together no matter where they are.
But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.
Since there are so many risks，why do we still have mobile phones？This is because these risks or disadvantages can be overcome. For example，while we are driving we can easily pull up our car if we really need to use the phone. Mobile phone manufacturers are reducing the radiation of mobile phones to avoid health risks.
Though there are both pros and cons of using mobile phones，we could easily see that there are more advantages than disadvantages. Moreover，mobile phones are becoming cheaper，which might be another reason why mobile phones are increasingly used today.

Supporters of home education claim that it is less expensive and far more efficient than mass public education.Moreover they quote several merits: relief of school overcrowding,added curricular and pedagogical (课程和教学法) alternatives,strengthened family relationships,lower dropout rates,increased motivation,higher standardized test scores,and reduced discipline problems.Supporters of home schooling also believe that it provides the parents with the opportunity to reinforce their moral values through education.
Critics of home schooling movement claim that it creates as many problems as it solves.They acknowledge that,in a few cases,home schooling offers educational opportunities superior to those found in most public schools,but few parents can provide such educational advantages.Some parents who withdraw their children form. the schools in favor of home schooling have an inadequate educational background and insufficient formal training to provide a satisfactory education for their children.Typically,parents have fewer,not more technological resources available than do schools.However,the relatively inexpensive computer technology that is readily available today is causing some to challenge the notion that home schooling is in any way not so good as more highly structured classroom education.
Finally,a sociological (社会学) concern is the restricted social interaction experienced by children who are educated at home.Technology will never replace the pupil-teacher relationship.Also,while relationships with parents and brothers and sisters may be improved,children taught at home may develop a distorted (歪曲的) view of society.
