Ss: ...

T: I’m so glad to share your dreams.Your ambition and careful thoughts really leave a good and amazing impression on me.I like them.In this unit, you will learn something about“Great scientists”.Maybe you will know what you need in your efforts to realize your dreams after we talk about some world-famous scientists.Before we come to“Warming up”, I’d like you to come to the new words in this unit, which will help you to learn this unit.

Step 3 Word puzzles

T: Open your books and turn to Page 92.Let’s read the words and expressions together.
