【学习目标】( Learning Objectives )
- Master some terms and phrases for this lesson.
- 2.Talk about the human brain and brain power.
- 3.Get general understanding and for specific information.
- 4.Look for more ways to increase brain power and present findings to the class.

【 Pre-task 】Read the text, translate the words, phrases and sentences, and then share in your group.
Step l. Translate the following words and phrases
- living matter _ _____ 9. locate________________

- It might also be a good idea to increase your intake of Omega-3 fats, which are an important brain food.
3. A good example of this can be seen in people who have lost an arm or a leg in an accident. Though they don't have an arm or a leg,they can still have feelings from it, like pain.

- ( ) 1 The brain consists of only white matter.
- ( ) 2 The brain weighs just over a kilo.
- ( ) 3 The brain contains about one billion cells.
- ( ) 4 The brain uses 10% of the body’s energy.
