Welcome to the Lesson.
In this lesson we look at how we use the how we use 'could' and 'was able to' to talk about ability.
Look at these sentences and especially at the words in red.  What do you notice?
 
1 When he was only six years old he could swim pretty well.
2 Because he worked so hard he was able to pass the examination.
3 Do you think he could pass the examination?
4 Do you think he was able to pass the examination?
5 When I was on holiday I could get up whenever I liked.

One of these sentences is about the future - all the others are about the past.

Which sentence is about the future?
