If you've read my advice about how to answer part 3 questions, you'll be able to analyse the answer below. Can you comment on the way I've organised or "built" the answer, and point out any good vocabulary and/or grammar? You should find several verb tenses, for example.
Do you think people will watch less television in the future?
Yes, I do think people will watch less television in the future, although that doesn't mean that they will watch fewer programmes or spend less time looking at screens. What I think will happen, and it's already happening, is that people will watch things on the Internet, through websites like YouTube. To use a personal example, I used to watch TV in the evenings, but now I often choose to stream videos, films and TV series through my computer instead.
