21st century is the century of technology. Nowadays, technology is everywhere around us. The development of technology has a significant effect toward the society. These new technologies make our life much easier and better. First,internet is a very useful tool for us today. The development of internet brings a great impact toward the society. Instead of going to library and reading all the books to figure out some information, we can just use the website to do research. The internet leads us to a place where we can find unlimited information and resources. It makes our life much easier and better. Another modern technology is mobile phone. Nowadays, many people have a mobile phone. It is very convenient to the users because we can talk to anyone we want with a phone as small as a wallet. Also,we can communicate with others by making a phone call instead of sending letters. Technological development has brought many benefits, but there are also many bad places. Like mobile phones, it is a good thing, but invested in students ' hands and that is not the same, they attend classes not to concentrate on, instead of using a mobile phone to play games or access to the Internet. In conclusion, I believe the development of technology brings significant impact to our life. It is very helpful to us and I believe technology will keep improving in future.
