Nowadays technology is an important aspect in human life. Technology is widespread almost all over the word. I think that we can't live without using it. Firstly, in working environment, in our society, we always use technology to work. At universities, in particular in language universities where computers are used to do listening, writing, researches and so on. At office which all the employees must be able to use computer, Internet and various types of computer's programs. In factories where machineries had replaced hand labor. Secondly, in daily life technology is always present. Young people continuously use their smart phones to keep in contact with friends. They fell uncomfortable if they are not online. A lot of children from early age became dependent by technology. This aspect has both positive and negative aspects. A positive aspect is that if children using Internet to research something useful for expand your knowledge, their will became surely independent learners. Instead a negative aspect is that if they all days chatting or surfing on the net they became unable to make real relationship. To sum up, I think that technology is necessary and indispensable in our life. We must look out for don't abuse of it.
