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.
For reference
1. You see a set of keys for typing. (keyboard)
2. You use it to store information. It can store more information than a floppy disk. (hard drive )
3. You see words and pictures on it. (screen)
4. It is a machine that puts words and pictures onto paper. (printer)
5. It is a small device moved by hand. It controls the cursor on the screen. (mouse)
6. It is a part of the computer where the sound comes out. (speaker)
7. These are sets of instructions that control your computer. (program)
8. It is a short, movable line on the screen. (cursor)
9. It is a small square of plastic on which a computer mouse moves. (mouse mat)
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.
4. Read the e-mail in Part C, which was written by Kenny to his grandpa about the Internet. You are required to complete the e-mail with the words discussed on page 38. Try to guess the meanings of the new words from the context. Then we’ll check the answers.
Answers
C (1) browse (2) search engine (3) web addresses
(4) links (5) website (6) web page
(7) home page (8) back arrow (9) refresh
(10) minimize (11) download (12) virus
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.
Answers
D 1 LOL 2 FYI 3 KIT 4 BRB 5 BTW
6 TA 7 YW 8 TIA 9 CU 10 ASAP

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 charge 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.
