In the past, technology, we thought , would make our lives easier. Machines would do our work for us, leaving us spending more time in doing something we like. People thought of technology as a solution to problems, not a creator of them.Technologically speaking, we assumed that we were leaving old difficulties behind and advancing into a new and more pleasant future. This was only partially true. For us technology did solve old problems, but it also created new ones. These problems are of various types.So I will show you the advantages and disadvantages of technology.The Influence Brought by ComputerAdvantages: (1)The computer can broaden our knowledge about the world. It can also help us learn more about many fields of studies quickly: science, medicine, arts and so on; (2) Has promoted the communication between our each other, because the computer was really convenient ; (3)It facilitate us to collect the material we need. Disadvantages: (1)The computer can affect our vision, if our long time looks the computer screen, does not let the eye make the suitable rest, like this can affect our vision, brings about the nearsightedness(近视）; (2)It also can affect our studies, many children become so addicted to computer games that they stay up late frequently and even neglect their studies .TelephoneIt has promoted the communication between our each other, because the telephone was really convenient and portable;It has many functions, for example, watching movies, surfing the Internet and so on, so it bring a lot of fun to us.But it also has bad influences on us. Such as, it has great radiation, which can do harm to our health. It can also affects our hearing. The Influence on Children Brought by TechnologyChildren can study more knowledge about modern technology ;Through systematic study in school, children can improve the qualities of study; They can figure out some information much easier and better by multifunctional technology If we depend on modern technology too much, it will bring bad effects especially to children.如果过分依赖于现代科技，那么它就会给我们，尤其是我们的孩子带来不良影响。

During the growth of children, basic education is essential. Computers and scientific tools should not replace school education. Through systematic study in school, children can oversimplify the life. In this way, children will become very lazy and unwilling to use their mind.在孩子的成长期间，基础教育至关重要计算机和科学工具不应取代学校教育通过在学校的系统学习，孩子们都能学会如何学习，如何创造和如何做人但是通过电脑孩子们只能学会如何简化生活这样一来，他们就会变得很懒惰并且不愿动脑 Besides, staying in front of the computer to long will do harm to childrens health. The radiation from the computer will arise many uncomfortable feelings. For instance, losing hair, not sleeping very well and having a headache, etc. The biggest harm to children is that staring at the computer for a tong time will damage the vision. So the children have to wear a pair of glasses early from their school days. It will do harm to the whole process of their growth.除此之外，在电脑前停留时间过长不利于孩子们的健康。

电脑射线会引起许多不适的感觉例如：脱发、睡眠不良和头痒等等最大的不利就是损伤视力因此，有些孩子不得不从上小学就带眼镜这对他们的成长是有害的In conclusion, I believe the development of technology brings significant impact to our life. I think that if we can overcome its negative effects, we can bring it into full use. It is very helpful to us and I believe technology will keep improving in future. 。
