Take turns to ask each other about your online habits.
 

EXAMPLE

A: It depends. I'd say from half an hour to three hours.

B: What do you usually do online?

A: I listen to music, stream videos, or look up information. And you?

B: Lots of things. I especially like to chat with my friends and family. By the way, what's your favourite app?

Step 10Pronunciation

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.

EXAMPLE

The Internet is becoming the town square for the global village of tomorrow.

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.

Listen to the poem and see if you got the stressed words right.

Step 11Function & Content Words

Content words are words with specific meanings, such as nouns, adjectives, adverbs, and main verbs (those without helping verbs.)

Function words include determiners, conjunctions, prepositions, pronouns, auxiliary verbs, modals, qualifiers, and question words.
