Step6 Writing
Write a report on Internet use.
Learning about the text type
A report is a piece of writing that provides information in a formal e to a conclusion based on facts and figures and avoid giving personal opinions when analysing a situation.
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.
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.
Sample
Report on Internet use
When the Internet was invented in 1969, no one could have known just how much it would change the world. The world’s first website was not built until 21 years later. Now there are more than 1 billion websites online.
There have been great changes in the way people use the Internet. The Internet has become more and more important and is now used for a greater variety of activities. It seems more people trust Internet security, as they are more likely to shop online or make online payments now than in the past. Both these activities saw big increases, from 38% to 63% and 32% to 65% respectively.
The biggest change in the past five years is the increase in people making travel bookings online. This increased from less than 10% to more than 40%. Also, the popularity of mobile Internet use has grown dramatically in the past five years. Moreover, it seems that people of all ages have taken to the Internet. Around 21% of users are now aged 40 or over, compared to 17% five years ago. The number of users under 20 has also gone up.
As far as I am concerned, people will probably spend even more time online in the future. It seems likely that people will continue to do more of their shopping and payments online. The trend of going mobile also looks likely to carry on.
