Speaking
Talk time:
Things to remember
In most sentences, we use the weak forms of articles, prepositions,
pronouns, auxiliary verbs, modal verbs, conjunctions, etc.
Some words have both a strong form and a weak form.
Strong and weak forms
In most sentences, we use the weak forms of these words.
Sometimes we use the strong forms for emphasis.
Listen to the conversation below. Pay attention to the pronunciation of the words in blue. Then practise it in pairs.
May: What’s your favourite subject, Ben
Ben: Maths. Our Maths teacher uses a lot of games to help us learn. He
makes the class really interesting. Also, I like to work with numbers.
May: OK. Do you know the number of students in your class
Ben: Yes, I do. There are 35 students in my class—18 boys and 17 girls. I
can remember all their birthdays!
May: You’re amazing!
