Tip: Listening for years
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.
separately [ sepr tli] 单独地；分别地
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.
In (1)_________ _____________ The first general-purpose computers
came onto the market.多用途的；多功能的

(2) _______________ along a network.

Tapescript:
Mr. Tan: 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.
general-purpose[只用于名词前] 多用途的；多功能的
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.
military [ m l tri]军事的；军队的；武装的
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.
increasingly | n kri:s li|越来越多地；不断增加地
Increasingly, training is taking place in the office rather than outside it.
在职培训日益增加，而不是脱产进行。
It is becoming increasingly clear that this problem will not be easily solved.
越来越明显的是，这个问题不会轻易解决。
definitely | def n tli| 肯定；没问题；当然；确实;确切地；明确地；清楚地
（二） 看
1. Answer the three questions in part B on page 37.
B. Mr. Tan also shows the students some charts about Internet use. View the charts below and answer the questions.
Tip: Viewing charts
There are different types of charts to show information. Bar charts(条形图) are often used to show how something changes over time or to compare different things. Pie charts(饼分图) are used to show percentages. Line charts (折线图) are often used to show trends. To understand a chart, it is important to read the title and captions(说明文字).
(1) According to the first chart, which use of the Internet has increased the most during the last five years
Travel booking.
(2) What change can you see from the two pie charts
More and more people have been going online using mobile devices.
(3) In the last chart, what change do you notice in the Internet users above 59
An increasing number of people above 59 use the Internet now.
2. View the chart about “Online activities by percentage”, and answer the following questions.
(1) Which use of the Internet has had the slightest change during the last five years
Entertainment.
(2) What did people use the Internet for the most five years ago What about now
Five years ago, people used the Internet the most for its search engines. And now it’s the same.
(3) During the last five years, which use of the Internet has decreased the most
3. View the chart about “Ways people access the Internet by percentage”, and describe the chart by using the following expressions.
Email.
Useful expressions
As can be conveyed/ illustrated/ reflected from the pie charts ...
There has been a rise/an increase/a drop/a decrease of ... per cent in the number of people ...
As can be reflected from the pie charts, over the past five years, the number of the users who access the Internet using mobile devices has risen from 69% to 95%, while the percentage of users who access the Internet without using mobile devices has dropped from 31% to 5%.
4. View the chart about “Ages of Internet users by percentage”, and describe the chart by using the following expressions.
Useful expressions
As can be conveyed/ illustrated/ reflected from the chart ...
There has been a rise/an increase/a drop/a decrease of ... per cent in the number of the Internet users with the age from ... to ...
The number of the Internet users with the age of ... has risen/ increased/ dropped/decreased from ... to .../by ... per cent ...
As can be conveyed from the chart, over the past five years, the number of Internet users has been increasing in most age groups, but the 20-39 age group has decreased by about 10%.
（三） 说
1. Provide more information on the topic of Internet use by filling in the following chart.
public commercial use of the Internet;
the world’s first website
ways people access the Internet
by percentage;
ages of Internet users by percentage
AI
AR增强现实技术 （Augmented Reality）, 是一种实时计算摄影机影像位置及角度并加上相应图像、视频、3D模型的技术，其目标是在屏幕上把虚拟世界套在现实世界并进行互动
2. Finish part C on page 38 based on the chart above.

The figure/number/percentage remains/ stays the same/ unchanged.
Possible answer
A: How has the Internet developed over the years
B: It was invented in 1969 and the first website was built in 1990. Within 24 years, the number of websites had risen to more than 1 billion!
A: Incredible! I know there have been great changes in the way it’s being used. Its popularity among people of all ages has grown dramatically in the past five years.
B: Exactly. Now around 21% of users are aged 40 or over, while five years ago, that percentage was just 17%. Users under 20 have also increased.
A: Interesting! Apart from the changes in user groups(用户组，用戶群), what other aspects of Internet use have changed
B: The use of online shopping and payments has gone up by about 25% and 30% respectively in the last five years! People trust Internet security more.
The biggest increase is in online travel booking though. The number has risen from less than 10% to more than 40%.
A: I’m not surprised. So what do you think the future of Internet use will be like
B: More people are using mobile devices to go online.
I believe the trend will carry on and mobile devices will become an even bigger part of our daily lives. The future is definitely mobile!

（四） 写

How can you improve your writing
3. Share your report in class and evaluate which report is the best one.
Possible answer:
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.
