Planning your writing Write a report on Internet use. Use your ideas from part C and the information in parts A and B to help you. Learning about the text type A report is a piece of writing that provides information in a formal style. Come to a conclusion based on facts and figures and avoid giving personal opinions when analyzing a situation. Learning about the structure To write a report on Internet use, you can follow the structure below: Briefly introduce the history of the Internet. Clarify the recent changes on Internet use. Predict the future of Internet use. Learning about the language Use simple and plain language to present your information in a clear and correct way. You can also include facts or statistics in your report. The history of the Internet. The recent changes on Internet use. The future of Internet use. A report on Internet use When the Internet was invented in 1969, no one could have known just how much it would change the world. At that time, computers are large and expensive, thus only some professionals can have access to the Internet. In the 1990s, common people gradually can afford to buy computers, which brought about the increase of Internet use. Over the past 30 years, the whole world has witnessed great changes in the way people use the Internet. Compared with online activities 5 years ago, more and more people use the Internet for information or E-commerce, including shopping, payment and travel booking, while fewer people use it to send e-mails. Meanwhile, there is a sharp increase of 26 per cent of people using mobile devices to access the Internet. However, the percentage remains almost the same when it comes to Internet users of different ages, with only slight increases in the Internet users from 0 to 19, from 40 to 59 and those above 59, which may be caused by the popularity of smartphones among people of all ages. As far as I am concerned, I think the Internet will definitely play an increasingly important part in our life and it will bring us more convenience and benefits as long as we properly take advantage of it. 115046.68 $$
