2- All about fishing
M: honey, look, it is sunny and warm. It is a good day for fishing. Let’s go fishing. Don’t forget take the fishing kit.
we need fishing rod/bait/a net/a bucket/waders/hat.
Don’t forget to put on your life jacket.
M: ready? Let’s go!
Row row row the boat....
M: Honey, Look, there are lots of fish jumping out over there. It is a great place to fish. Please stop rowing the boat.
First Put a bait on the hook, and then throw the fishing line in water. We should keep quiet. Any noises will scare the fish away. And we should be more patient.

here is a big empty aquarium. Please stick the sea animals in it.

Alligator: less aggressive;短吻鳄主动攻击性较弱 Crocodile: more aggressive.鳄鱼更具主动攻击性，更危险。
M: baby, I will show you some pictures. What are these animals?
M: Look at them from the top view, the U-shape head is alligator and the V- shape head is crocodile. When they close the mouth, the alligator’s upper teeth are visible, but all crocodile’s teeth are visible.
Usually alligator is in dark color and crocodile is in light color. Alligator lives in swamps, lakes and river. It Doesn’t run fast on land and water. But crocodile live in saltwater as the sea. It runs much faster on land and water. So alligator is less aggressive, crocodile is more aggressive
the funny fact of crocodile is it release heat through their mouth, because it doesn’t have sweat gland
M: now you are going to row a the stream. If you see alligator or crocodile, don’t forget to scream。
