Teaching Procedures
Welcome to the unit
Step 1: Brainstorming
With the rapid development of Internet, it has been influencing our daily life tremendously. Internet has transformed our lives and the way we communicate, we learn, we work and spend our free time. In fact, it has more or less changed every aspect of human society.
Boys and girls，please read the instructions and focus on the four pictures. Then
try your best to think of information you know about each picture. Anyway, I’ll give you a brief introduction first. (For example, “We are going to talk about how we use the Internet. Try to find how we can use the Internet and how the Internet can affect our lives.”)
Picture 1
What can people do on this website?
What do we call this kind of website that provides
searching services? (We call it search engine.)
Do you know how to find information on the internet
using a search engine?
What search engines do you know or often use? Which is your favorite search engine?
Picture 2
Have you ever heard of shopping online or bought anything online? What is shopping online like?
What do you think would be the advantages of buying things online? (As online shopkeepers do not have to pay for the rental of a real shop, the products sold on line are usually cheaper than those in real shops. It is easy and convenient to compare a
product in several online shops. Paying for things is
simple as you just key in the credit card number and
confirm the payment online. The delivery is usually
quick and the online shops provide delivery to your
home. The most important thing is that shopping online
saves a lot of time. )
What do you think would be the disadvantages of online shopping?(Because people can only see pictures of the products online, sometimes you could receive something that was not what you really wanted. The safety of the payment is not one hundred percent guaranteed as someone may steal the account numbers or pin numbers of your credit cards registered online. Also, some
people falsely advertise products and then steal customers’ money. )
Picture 3
Have you ever tried talking with your parents or friends online? What was it like?
What devices do you need if you want to talk with people
online?(A computer connected to the Internet, a web-camera, a
web-microphone and web-talking software.)
What are the good points and bad points of online talking?
(There are many good things about online talking. People can save
a lot of money instead of paying for long-distance calls. People can
keep in touch with family members or friends wherever they are in
the world. There are negative things too. The quality of the pictures or voice depends on the speed of the network transfer. Many people talk with online friends without realizing that their pictures could be used by others in illegal ways. )
Which way of communication do you prefer, talking face to face, talking over the telephone, talking online or talking online with a web-camera? Why?
Picture 4
Have you tried other online services that are not mentioned
here? Which ones?
What other online services do you think we will need or have in the future?
What role do you think the Internet will play in the future?
Do you think it is a good idea to “live” on the Internet completely?
Step 2: Sharing information
1. To work in groups of four or to form your own groups. Let’s read the three questions under the pictures.
2. Exchange your opinions and discuss the three questions among your group members. I want all of you to fully participate in the discussion and express your opinions freely. Then some of you are required to report your answers to the class. Remember it may be more interesting for groups to exchange and compare your answers.
Step 3: Discussion:
What are the advantages and disadvantages of the Internet?
Sample answers
With the rapid development of Internet, it has been influencing our daily life tremendously. Internet has transformed our lives and the way we communicate, how we learn, how we work and spend free time. In fact, it has more or less changed every aspect of human society.
We can benefit a lot from Internet. Firstly, it is more convenient than ever before. Internet has greatly shortened the distance among human beings. E-mail is much more efficient. To do some research work, we can search for relevant information on Internet without leaving our home. Secondly, we can reduce our cost greatly. We needn’t spend lots of time and money in p rinting and posting. What we have to do now is just to send documents through Internet and it almost costs nothing.
Although Internet has brought us many benefits, there can be no denying that it has brought us many inconveniences, even harms as well. First of all, it is not safe on Internet. Maybe thousands of people are staring at you when you log onto Internet. Your private information, such as your account and password, is easy to be let out. On the other hand, with the sharply increasing amount of time spent on Internet, we are starting to lose ourselves, especially for those youngsters. We are getting more and more indifferent to people around us. The more we communicate, the lonelier we feel.
However, Internet itself is neither right nor wrong. We can benefit from it and may also suffer from it. Nobody can hold back the step forward of Internet. If we resisted it, we would certainly lag behind other nations. What we should do is to take full use of its advantages and try to avoid the harms it may bring as well.
Step 4: Homework:
1. Collect more information about the development of the Internet.
2. Prepare the Reading part.
Reading The effects of the Internet on our lives
Step1: Lead-in
Nowadays, internet is playing an increasingly significant role in our society. Since its appearance, it has brought enormous changes to our lives. It seems that no one can escape from the influence of it. As to whether it is a blessing or a curse, there is a long-running controversial debate. Some people think that increased use of the Internet leads to social isolation and depression. People who spend more time on the Internet spend less time socializing with peers, communicate less within the family and fell more lonely and depressed.

Word power
Step1: Brainstorming
1. Guessing Game:
At the beginning of today’s class, let’s play a guessing game. Here are several cards, each of which is related to the Internet or a computer. I’d like one of you to give a brief description of the each device and other students to guess what it is.
2. Next time you are in our school’s computer room, notice how we operate a computer.
Step 2: Vocabulary learning
1. Do you know about the operation of a computer and the knowledge of Internet? We’ll conduct a question-and-answer activity. Please speak out what you know as much as possible. The purpose of this activity is to make you more familiar with the words and terms connected to the Internet.
2. Read Part A and make sure that you know what these words in blue mean or refer
to in Chinese.
3. Focus on Part B and read the sentences individually first. Make sure that you know what these words mean or refer to in Chinese.

Step 3: Vocabulary extension
1. In Part D, you will learn some abbreviations that people use in Internet chat rooms. Whether you have used these abbreviations before? As the abbreviations use only the first letters of each word, it is fast to type them when chatting online. It is very popular among young people to use these words.
2. You can sometimes work out what an Internet abbreviation stands for by reading the letters out loud, for example:
B4 (before)
OIC (oh, I see.)
CUL8R (see you later.)
I’ll explain some other expressions to you:
BTW (by the way)
BFN (bye for now)
3. Complete Part D individually. Then we’ll check the answers.
4. Reading:
words: 288 time: 4’20’’
The Internet began in the 1960s as a small network of academic and government computers primarily involved in research for the U.S. military. Originally limited to researchers at a handful of universities and government facilities, the Internet has quickly become a worldwide network providing users with information on a range of subjects and allowing them to purchase goods directly from companies via computer. By 1999, 84 million U.S. citizens had access to the Internet at home or work. More and more Americans are paying bills, shopping, ordering airline tickets, and purchasing stocks via computer over the Internet.
Internet banking is also becoming increasingly popular. With lower overhead costs in
terms of staffing and office space, Internet banks are able to offer higher interest rates on deposits and charg e lower rates on loans than traditional banks. “Brick and mortar" banks are increasingly offering online banking services via transactional websites to complement their traditional services. At present, 14 percent of Internet households conduct their banking by means of the Internet, and the figure is expected to double or triple during the next two or three years.
Increasing commercial use of the Internet has heightened security and privacy concerns. With a credit or debit card, an Internet user can order almost anything from an Internet site and have it delivered to their home or office. Companies doing business over the Internet need sophisticated security measures to protect credit card, bank account, and social security numbers from unauthorized access as they pass across the Internet. Any organization that connects its networks to the global Internet must carefully control the access point to ensure that outsiders cannot disrupt the organization’s internal networks or gain unauthorized access to the organization’s computer systems and data.
1. According to the text, Internet banking ________.
A. requires minimal usage fees
B. offers price advantages to users
C. is more efficient than traditional banking
D. is environmentally-conscious
2. The term “brick and mortar banks” (Line 3, Para.2) refers to ________.
A. banks with dependable reputations
B. banks with competitive interest rates
C. banks with traditional walk-in services
D. banks with reliable on-line services
3. The last sentence of the third paragraph tells us that ________.
A. any organization's networks may be at risk of security breaches
B. current technology cannot safeguard against unauthorized access to online networks
C. information security should be a pressing concern for Internet commerce
D. organizations must secure their networks and data against unauthorized use
4. What is this text mainly about?
A. Conveniences brought to consumers through use of the Internet.
B. Implications of increasing commercial use of the Internet.
C. Security risks posed by commercial use of the Internet.
D. Advantages of Internet banking versus traditional banking.
5. Which commercial usage of the Internet does the author NOT refer to?

Task Getting news from the Internet
Skills building 1: reading charts and graphs
When you are learning about a new topic, what information is most important besides opinions? (Facts and figures)
Now I’ll present you a chart. Please look at it carefully and try to tell me what this chart can tell us.
(The bar chart above shows the weight in kilograms of some fruit sold one day by a market. We can see that 52 kg of apples were sold, 40 kg of oranges were sold, and 8 kg of star fruit were sold.)
So, when listening, we need to be able to collect facts and figures, which are often presented in the form of charts and graphs. You are expected to learn some different types of graphs and charts that use bars, lines or circles to show information. .
Read the guidelines in Skills building 1 on Page 42. Focus on how to understand different kinds of charts and graphs.
Step 1: collecting information:
1. Pair work:
Have a discussion with your partner:
If you want to attend a series of lectures about the ways people watch or listen to the news, what should you pay special attention to?
2. Listen to the first speech and take notes in the space.
3. Now, please go over the instructions in Part B and read the three sentences. Try to guess what the speech that you are going to listen to is about and what words will be used to complete these sentences before you listen to the recording.
Please check the answers.
4. Please read the instructions of Part C. Look at the bar chart and pay special attention to the legend, the side (y-axis) and the bottom (x-axis).
5. Please look at the pie chart and read the question and the legend and try to finish
the remaining questions.
6. Discussion in groups of four. Why 50 per cent of people trust the news sources from national TV and local TV, while only 7 per cent of people trust the news on the Internet.
Skills building 2: forming more detailed questions
1. What we can do if we want to get more detailed information when we already know a little about a topic? (One of the ways is to ask more questions on this topic.)
2. Read the guidelines and the three parts on page 44 and try to understand how to get more detailed information.
Step 2: asking more detailed questions
Now, let’s use the skills we just learned to get more detailed information. Suppose you need to ask one speaker his opinion on the situations that people gets news from the Internet.
1. Work individually to think up and write down as many questions as you can to find more detailed information. You can consult the prompts in the left column on page 44.
2. Work in pairs, one asks questions formed from the prompts in the left column, and the other answers these questions using the prompts in the right column. After that, I’d like you to present the questions and answers in front of the classroom.
Skills building 3: reporting on facts and figures
Sometimes we need to write a report on certain topic. What shall we pay attention to when we write a report? For example, when you are asked to write a report on how
the students in your class think they should spend their time, what should you include?
1. Read the guidelines in this part to find out what are the two main things to focus on.
2. Please read Part 1 and try to get how to state facts and opinions. Then try to tell us which of the following are facts and which are opinions.
1) Computers are still too expensive for many people. (fact)
2) I think reading newspapers is the easiest way to get news. (opinion)
3) You can not only see‘real’images on TV but also hear them talk. (fact)
4) News on the Internet is updated every hour. (fact)
5) Some people consider Internet news to be unbelievable. (opinion)
Step 3: e-mail a report
As mentioned above, you are expected to know how to express facts and opinions. Now, let’s have a practice. Let’s write a report using the information gathered in Steps 1 and 2 and e-mail it.
1. First let’s divided into small groups and then make an
arrangement. Remember each member of the group should
contribute to the planning of the outline of the report. You should pay special attention to in what position you should write the report and to whom you will write the report.
2. I’d like several students to read your e-mails to the class.
Possible example
Dear Sir,
I went to listen to two speeches about the ways people get news. From the first speaker, I know there are different types of news, such as sports results, weather, politics and current affairs, and some of them are most suited to sources like radio, newspapers, and television. There is no doubt that the Internet is increasingly popular, but the number of people who get their news from the Internet is still small. I have collected some figures from two charts, each of which is a survey of 500 people. According to the two charts, the percentage of people who turn first on the Internet for news on emergency, opinions, weather, breaking news and sports results is
