3—6 年级:A red kite、The lost lunchbox、Two plant pots;先观察,再动手和挑战。
I have a red kite. My brother has a blue kite. We fly them in the park on Sunday. There is no rain.
Nora leaves her lunchbox on a bench. She returns after class. Tom is waiting beside the bench with the lunchbox. “Is this yours?” he asks.
We put two similar plants near a window. We water one plant but forget the other for several days. The dry plant starts to droop. We ask our teacher how to care for it.
