Write a Unit 4 word on the board (e.g., 'planet').

The team that keeps the chain going without repeating or hesitating for more than 5 seconds wins!
Answer / Example: No fixed answers — focus on vocabulary recall and speed.
Game 2: Guess the Word (你说我猜)
Prepare slips of paper with Unit 4 words.
One student comes to the front, draws a card, and describes the word without saying it (e.g., for 'whale': 'It lives in the sea. It’s very big.').
The class guesses the word.
Each correct guess earns 1 point.
Answer / Example: Example: 'It’s very cold' → 'freezing'; 'It’s made of sand' → 'desert'.
Game 3: Environmental Detective (环保侦探)
Show students several pictures (pollution, plastic bottles, forests, whales, etc.).
Students work in groups to use as many Unit 4 words or phrases as possible to describe the pictures in English.
