History
Present
Sample-body
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%.
Opening
Online activities: chart 1
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.
Ways people access: chart 2
Ages of users: chart 3

Early mobile phones were not as functional as they are now and were used for basic communication needs: telephoning and messaging. Mobile Internet was not available then, so people depended on their computers or laptops to surf the Internet. Since the invention of the smartphones, mobile access to the Internet has helped users with more than just basic needs. They could now do most daily tasks on a device that fits into their pockets, for example, instant video calls, online shopping, watching videos, reading the latest news reports, and searching for information anywhere at any time.
Homework
Search more information or reference materials, and How do we use the Internet properly and responsibly
Write a short paragraph about a comparison of the life before and after smartphones were invented.
