I think the most important modern invention is the Internet. With the Internet, we can do many things. For example, we can shop, learn knowledge, listen to music, and watch movies online.
The Internet makes the world smaller. We can meet and talk to friends and relatives far away without spending a lot of money. We can also post our blogs online so our friends can know what we are doing by visiting our websites like zuowendidai(Joozone). Internet makes our life more exciting and easier.
