Step1Lead-in
Activity 1
1.Look at the sentences from the reading passage and answer the questions.
a That is why Letters from Father Christmas could be the perfect book...
b The children must have been very excited as they opened it.
c ...they might not receive their presents if they were not good.
(1) What do the words in bold indicate: an order,a request,ability or possibility?
(2) Will the meaning of sentence (a) change if we replace “could” with “must” or “might”?
(3) What happens if we change “must” and “might” in sentences (b) and (c) into “could”?
(1) possibility
(2)If we replace “could” with “must”, the meaning of sentence (a) will change. It means the speaker is quite sure about the statement. If we replace “could” with “might”, the meaning of sentence (a) will remain more or less the same. “could” and “might” in affirmative sentences have a similar meaning when indicating possibility.
(3)If we change “must” in sentence (b) into “could”, it means the speaker is not sure about the statement, and it’s only a possibility. If we change “might” in sentence (c) into “could”, it means it’s impossible for the children to receive their presents.
2.Look for more sentences with modals in the reading passage.
①The children must have been very excited as they opened it.
②...they might not receive their presents if they were not good.
