Be careful when listening for years: it is normal to treat the first two numbers and the last two numbers separately, but there are various ways of saying them.
In general, speakers try to use the shortest way possible, for example, 1979 (nineteen seventy-nine), 2003 (two thousand and three), 1805 (eighteen o five).
Sometimes we add mid- before a certain year, e.g. mid-2008. We also use expressions like the early/late 1980s.

Tapescript
Good morning, class. Today I’m going to talk about the Internet. I’m sure all of you use the Internet, but what do you know about it Now let me tell you about its history and development.
The first general-purpose computers came onto the market in the early 1950s, but it was only in 1969 that scientists invented a way for computers to communicate with each other. This meant that computers allowed people to pass messages along a network and talk to each other. To start with, only four computers were connected and the network was for military use. Public commercial use of the Internet began in mid-1989.
One of the main applications of the Internet is the World Wide Web. Pages on the World Wide Web are called websites and can be accessed through the Internet. They were originally used as a space for scientists around the world to share information. The world’s first website was built in 1990 by Tim Berners-Lee, a British scientist. He then taught others how to build their own websites, allowing the Internet to grow.
Within 24 years, there were more than 1 billion websites online. Two years later, in 2016, 3.6 billion people were using the Internet—about 48 per cent of the world’s population at the time. And increasingly, people are using their phones to access the Internet. The future is definitely online and it’s definitely mobile.

Tip
Viewing charts
There are different types of charts to show information. Bar charts are often used to show how something changes over time or to compare different things. Pie charts are used to show percentages. Line charts are often used to show trends. To understand a chart, it is important to read the title and captions.
Mr Tan also shows the students some charts about Internet use.

Report on Getting Students Interested in Reading by Starting a Book Club
From our recent survey of students, we have found that different students like reading different types of books. The most popular reading subject is humour, which 28 per cent of the students enjoy. This is closely followed by travel books, sports and science books. A small number of students like other subjects, such as history.
We want to get the students interested in reading. For this reason, I suggest that we have a humour book club, since humour is the most popular subject. Each class would have its own club meetings once a week. At the meetings, they could even read aloud some funny bits of the books.
