1. Complete the text with the correct form of the verbs in brackets ().
Tom is eight years old, and he can ____________ (play) the piano really well. He started playing
when he was very young. When he was four, he ____________ (can't) read or write, but he
____________ (can) play the piano and sing songs at the same time. He was so small that his
mother ____________ (must) put his high chair in front of the piano. Tom's piano teacher thinks
that he ____________ (can perform) professionally when he's ten. Of course he'll still be at
school and he ____________ (can't miss) classes or stay up late, but weekend concerts will be
possible. Performers need a lot of practice, so Tom ____________ (must) stay inside and
practise while his friends are playing. But perhaps when he's older, he ____________ (not have
to) find an after-school job because he'll earn money from playing the piano.
