口语素材：Invention（Internet）

If you ask me what's the most important technological invention in the 20th century, I will definitely say 'internet', because I believe that internet has dramatically improved the quality of our lives. First, it‟s now very convenient to calculate and analysis data and to search for information. Second, the internet has made the pace of life faster than ever, and everything could be done more efficiently. It once took my parents a month to find satisfactory information from a library, but now when I am doing the similar things, thanks to the internet, all the materials can be displayed on the computer screen within only a few seconds.

The invention changed my life most is internet. First, when internet was invented, people could find all kinds of information on it, like news, music, books and ads. It is convenient as long as a person has a computer. Secondly, communication among people becomes more frequently after internet has been used. People like to chat with their family and friends by internet because it is very fast and with nearly no expense at all.In addition, education has improved a lot because of the internet as nowadays students are more likely to turn in their homework and ask question to their professors by using internet.
