Dear Rita，    How are you？ Last time you asked me about the greatest invention in my eyes． I have also discussed it with my best friends， Anna， Sue and Kris． We have different ideas． Anna thinks it is the high﹣speed railway； Sue， the shared bike； Kris， the online shopping； and I prefer the Internet．    The Internet is just like a net， and it connects us with the world． In the past， it was nearly impossible for people to communicate immediately with people in other countries． They had to spend a long time to reach their destinations （目的地）， and not everyone could do that． But the Internet has made the impossible possible． Now we can communicate with foreigners online．    The Internet also helps us know what is happening around the world， and has made our life and work easier． In recent years， shopping online is very popular． We can just stay at home and buy what we need online． We can also do online office work and distance education． Besides， we can watch movies， listen to music and even play games to relax ourselves on the Internet．    So， I think that the Internet is one of the greatest inventions． It has changed our world! Although there are still many problems with the Internet， they will be solved in the near future． As a student we should make good use of the Internet!                                                                                                                                                                                                                        Yours，                                                                                                                                              Martin
