Task 2 Listening strategies
This part is designed to help students develop their listening skills by listening to a science lesson about the brain and its power.

* Before you listen, read the text and predict what kind of information you need, e.g. the first gap in Ex 2 is probably a color. Remember, you may need more than one word.
