Lead-in
It means the Internet has made the world closer together; we can interact on the Internet just like meeting at the square.
Before Listening
When and why do you begin to use the Internet?
What do you often do on the Internet?
While Listening
Sam: Hi, guys! I’d like to ask you some questions about your online habits.
First, how much time do you spend online every day? Anna?
Anna: It depends. I’d say two or three hours.
Sam: How about you, Paul?
Paul: Oh, maybe about two hours. Sometimes more. What about you, Joe?
Joe: Well, I think I spend at least an hour every day.
Sam: What do you usually do online, Joe?
Joe: I have a blog. It’s like an online diary where you write about something you’re interested in. For example, I like basketball, so I write a lot on my blog about my favourite team. It’s fun.
After Listening
Listening strategy: Listen for definitions
When you hear a word you don’t know, pay attention to the next sentence or two to see if there is a definition. Definitions often begin with words like “it’s like”, “that is”, or “for example”.
Pronunciation
Most sentences have two basic types of words: content words and function words. Content words are usually stressed. Read the sentence and notice which words are stressed.
Read the poem about online safety and mark the words that should be stressed.
Cyber Sense
I always keep things secret when I go online.
I never share the things that should be only mine.
My email and my home address, my phone number and name— These are things only I should know on websites or in games.
And so I use a nonsense name for my net identity.
When folks online ask who I am, I say, “I’m Cyber Me”.
And if I ever think that someone online isn’t all that bad.
I never ever meet them without telling Mum or Dad.
