Step I Lead-in
Talk about high-tech living with students.
T: Advancement ( http: / / www.21cnjy.com )s in communication and entertainment technologies are changing the way we communicate with each other and the world around us. Modern communication allows people to contact each other with the push of a button or click of a mouse. Video games are becoming a more socially acceptable form of entertainment. Through widespread use of email, cell phones, and instant messaging, individuals are able to keep in touch with friends and family instantly. Online gaming brings people of common interests together and allows for the development of imaginative and strategic skills. However, we may find our life is a little different now. For example, people now prefer to talk on cell phones rather than to the person beside them. Instead of face-to-face communication, they choose to email or send an instant message, resulting in a lack of physical contact. That is, high-tech brings us convenience, and problems as well. Now please look at the pictures on page 57 and talk about them.
Step II Speaking
Ask students to wor ( http: / / www.21cnjy.com )k in pairs and describe the items in activity 1 and answer the questions.
After discussion.
T: What are in the picture
S: They are an MP3 ( http: / / www.21cnjy.com )player, PDA, mobile phone, X-box, computer, digital camera in the picture.
T: Can you describe the items and what they are used for
S: MP3 players come ( http: / / www.21cnjy.com )in various shapes and sizes. They look like cars, pens and so on. MP3 players are used for listening to music, audio texts, etc.
S: Personal Digital Assistants (PDAs) are handheld devices ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) that were originally designed as personal organisers, but became much more useful over the years. PDAs have many uses: calculating ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), use as a clock ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) and calendar ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), playing computer games ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), accessing the Internet ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), sending and receiving E-mails ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), use as a radio or stereo, video recording ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), recording notes, use as an address book ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), and use as a spreadsheet ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ). Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) (smartphone ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 )), web browsers ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) or media players. Many PDAs can access the Internet ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), intranets ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) or extranets ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) via Wi-Fi ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), or Wireless Wide-Area Networks ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) (WWANs). One of the most significant PDA characteristic is the presence of a touch screen.
S: Mobile phones are p ( http: / / www.21cnjy.com )ortable for us. They are used for communicating with others and sending short messages.
S: An X-box is an X-like machine used for playing video games.
S: Computers are u ( http: / / www.21cnjy.com )sed for sending email, chatting with your friends, searching for useful information and so on.
S: Digital cameras are used for taking photos.
T: How many of the things shown in the photos do you know
S: There are five things shown in the photos I know.
T: How many of them do you use or play with
S: There are four things I use and play with.
T: How many of them do you want to own

T: Choose two most ( http: / / www.21cnjy.com )important things for you. Give reasons why you couldn’t live without them.
S: Mobile phones and ( http: / / www.21cnjy.com ) computers are important for me. The reasons why I couldn’t live without them are that I use a mobile phone to communicate with my friends and relatives and sending short messages to them and I use a computer to send emails, chat with my friends, search for useful information, etc. .
Then ask students to fill in the table in activity 4.
Two minutes later.
T: How often do y ( http: / / www.21cnjy.com )ou talk on your mobile phone with your friends And how long do you spend talking on your mobile phone with your friends
S: I talk on my mo ( http: / / www.21cnjy.com )bile phone with my friends once a day. I spend an hour talking on my mobile phone with my friends.

T: How often do ( http: / / www.21cnjy.com )you plan your activities on an electronic planner or diary And how long do you spend planning your activities on an electronic planner or diary
S: I keep diary to pl ( http: / / www.21cnjy.com )an my activities once a day. I spend ten minutes keeping diary to plan my activities.
T: Many of us can't ( http: / / www.21cnjy.com ) get through a day without scanning, dialing or logging into a digital world so deeply embedded that living without 1s and 0s seems almost unthinkable -- and maybe impossible. Now work in pairs and discuss your answers to the questions and say which activity you prefer.
Sample dialogue:
S: I prefer readi ( http: / / www.21cnjy.com )ng a book. It is less harmful than computers do to my eyes.
S: I prefer play ( http: / / www.21cnjy.com )ing a computer puter games are more interesting and real-like.

T: We now li ( http: / / www.21cnjy.com )ve in an era where the technology is becoming extremely important.

Check the homework ( http: / / www.21cnjy.com ) and then talk about computer science with the class.
T: Who could have ( http: / / www.21cnjy.com )imagined, in the mid 1970s, for example, that by the end of the 20th century, computers would be as common in people’s homes as TV sets In the 1970s, computers were common enough, but only in big business, government departments, and large organizations. These were the so-called mainframe machines. Mainframe computers were very large indeed, often occupying whole air-conditioned rooms, employing full-time technicians and run on specially-written software. Though these large machines still exist, many of their functions have been taken over by small powerful personal computers, commonly known as PC. Almost all of young people have personal computers of their own. All teenagers enjoyed playing computer games and surfing the Internet. If you click onto a search engine webpage and type in the word “Internet”, you’ll see a list of weblinks appear on the computer screen. The greatest impact of the Internet has been the creation of the World Wide Web. Do you know who is the father of the World Wide Web
S: Tim Berners-Lee (1955).
T: What do you know about him
S: As a child, Be ( http: / / www.21cnjy.com )rners-Lee made computer models out of old cardboard boxes. While at Oxford University, England, he built his own computer using an old TV and a few electronic spare parts.
S: After universit ( http: / / www.21cnjy.com )y, Berners-Lee worked for the European Council for Nuclear Research. With the help of fellow researchers, he built a special system for information searching. This system evolved into what became known as the World Wide Web.

T: Technology i ( http: / / www.21cnjy.com )s a tool. Is society headed toward improved lifestyles through these technological advances, or toward being controlled by technology itself The direction that society will take depends entirely on how individuals choose to use technology. This period we will read about computer viruses and crimes.
Step II Reading
Ask students to read the passage and do the activities related.
T: Do you know what a computer virus is
S: A program or piece of code ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) that is loaded onto your computer ( http: / / www.21cnjy.com" \l "#" \o "欢迎登陆21世纪教育网" \t "_blank ) without your knowledge and runs against your wishes.
T: Some people distinguish between general viruses and worms. A worm is a special type of virus that can replicate itself and use memory, but cannot attach itself to other programs.Viruses can replicate themselves. All computer ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) viruses are manmade. A simple virus that can make a copy ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) of itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it will quickly use all available memory ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) and bring the system ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) to a halt. An even more dangerous type of virus is one capable of transmitting itself across networks ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) and bypassing security ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) systems ( http: / / www.21cnjy.com" \l "#" \o "欢迎登陆21世纪教育网" \t "_blank ). Since 1987, when a virus infected ARPANET ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ), a large network used by the Defense Department and many universities ( http: / / www.21cnjy.com" \l "#" \o "欢迎登陆21世纪教育网" \t "_blank ), many antivirus programs ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) have become available. These programs ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) periodically check your computer system ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) for the best-known types of viruses. Now please read the passage and find out the answers to the questions in activity 1.
Sample answers:
1. Viruses attacked computer systems through the Internet.
2. Sven Jaschan ( http: / / www.21cnjy.com ) invented a deadly computer programme that made other people’s machines turn off.
3. Some teenagers ( http: / / www.21cnjy.com ) write computer viruses because they think of creating such programmes as a challenge.
4. If someone gets c ( http: / / www.21cnjy.com )aught writing a virus, the punishment can be heavy.
Then ask students to finish activities 2—4 on page 65.
T: Few professio ( http: / / www.21cnjy.com )nal programmers think that writing a virus is difficult. But a teenager find writing a virus is a challenge or an act of protest. In fact, most of these teenagers don’t know what they are doing can affect the wider world. Even they don’t think they have an impact on another person. Once they realize that it can have an impact on other people, most of them stop writing viruses. Everyone will have to pay for his action. Jaschan made no exception. Now read the passage again and do the rest activities.
Check the answers with the class.

2. grow out of sth:
(1) to become too big to fit into a piece of clothing
E.g. He’s already grown out of his school uniform.
(2) stop doing sth. as you become older
E.g. Most children suck their thumbs but they grow out of it.

Computer and Video Games : The Pros and Cons
Computer and vid ( http: / / www.21cnjy.com )eo games have been very popular among children and teenagers aged between seven to sixteen.
Gaming industries now have a new strategy to market their games – the medical benefits of playing games. Not only medical benefits but also educational. We cannot just ignore it as a cheap marketing strategy because they do have researchers and doctors to back them up.
Researchers have found that frequent game players score better at vision tests as compared to non players. It has also been found that playing these games could improve children's logical thinking ability and problem solving skills. Games such as SimCity, Age of Mythology, etc where gamers have to build houses, cities and develop war strategies help them to develop their logical skills and also help in decision making. Educational games help to improve their communication and problem solving abilities, alertness, locating things easily without straining too much and so on. American teachers have also found improvement in their students’ mathematics, spelling and reading amongst children who play these games. The government is pondering and researching ways to integrate such games into the academic curriculum.
Where on one hand the games do prove to be beneficial to an extent, at the same time, its ill effects cannot be ignored. Doctors have found a possible threat to these frequent gamers, affecting their mon complaints found among children obsessed with games are eye strains, wrist, neck and back pains, etc.
Specialists have confirmed that children who spend too much time playing computer games not only are easily susceptible to long terms problems like bad posture and RSI (repetitive strain injury), but it also causes a disequilibrium in their daily routine.
Spending many hours in front of the monitor and not going out enough could also cause social problems thus resulting in them becoming shy and introvert. Apart from that the games developed nowadays happen to be a lot more violent thus the gamers do have a tendency to lose control and become more aggressive.
Parents need to keep track of how much time their children spend in front of the screen playing games and also as to what type of games they play. Every aspect has its advantages and disadvantages; so is the law of nature. What we can do is try to maintain a balance and get the best of what it has to offer, be it nature or technology.

Complaint letter template ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) - This template is to help you draft your own letter of complaint. You can download a copy into your own word processor application.
Before you complain
Be clear in your ( http: / / www.21cnjy.com )mind why you are dissatisfied. Was it the way you were treated A wrong decision Defective goods What exactly went wrong
Be clear in your own ( http: / / www.21cnjy.com ) mind what you want to happen as a result of making a complaint. Do you want an apology Do you want a different decision Do you want the proper service that should have been provided in the first place Do you want replaced goods You should mention this to the organisation you are complaining to and ask for prompt action.
Who to complain to
This will be d ( http: / / www.21cnjy.com )ifferent depending on what type of organisation you are complaining to and the scale of your complaint. The following four steps are a general guideline. For more specific complaint procedures see the Information Section where you can find the specific steps for each organisation;
You should attempt t ( http: / / www.21cnjy.com )o resolve your complaint directly with the parties involved: i.e. take the product purchased back to the shop, or attempt to have the service redone.
You should contact t ( http: / / www.21cnjy.com )he relevant senior management or customer services department. It may be necessary to communicate with them several times before taking the next step. Most good organisations will have internal complaints procedures and complaints are often resolved using these. However sometimes they aren't and that's when you should consider the third step. It is worth mentioning that you are considering or have decided to take your complaint to the relevant authorities, sometimes this may provoke more serious consideration of a complaint
You should contact ( http: / / www.21cnjy.com ) the relevant authority or overseer who will be able to give advice on how to exacerbate your complaint if you are still not satisfied. Ask the institution which is the relevant independent ombudsman or adjudicator to whom you can take your complaint (you can also find this information by browsing the Information Section of this site). Alternatively you can contact your local Citizens Advice Bureau or Trading Standards Office who will be able to help and give you advice on who you should contact next. Some Ombudsman or executive agencies such as Oftel or Ofgem may take complaints up for you.
Finally, if all else has failed then court or arbitration services maybe the final choice. The Legal Section ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网 ) on this site contains information regarding legal options. Small claims court proceedings are inexpensive but time consuming and arbitration is available for many industries and services.
What to Remember
Various valuable hint ( http: / / www.21cnjy.com )s which should help you to get the result you are looking for:
Keep a record of even ( http: / / www.21cnjy.com )ts. If you speak to someone on the phone make a note of who you speak to, when and what was said. If you use 'snail mail' then keep a copy of your letter and any replies you receive.
Keep the evidence. R ( http: / / www.21cnjy.com )etain all receipts/invoices, letters and e-mails regarding products and services that you may have purchased/received. If you are asked to present these at any stage then present copies and keep the originals yourself.
Stay Calm. If y ( http: / / www.21cnjy.com )ou have confronted someone directly then don't let the emotion of the moment get to you. If you are clearly not getting an adequate response then simply take the next step in the procedure as advised above. Don't be shy
