拓展提高（课内同源 + 课外同源）

Passage1（课内同源：叶子的绿色工厂）

　　What does a green leaf do all day? In Ms Lin's science class, the students have a name for it — the “green factory”. The name is just right, because a leaf works like a small factory, and its product is life. / The factory works in the day. It needs three things: sunlight from the sky, air from around it and water from the soil. The roots of the plant bring water up from under the ground, and the leaf takes in air through tiny doors on its back. With sunlight, air and water, the leaf makes food for the whole plant. / This food helps the plant grow tall and strong, and it feeds animals and people too. Cows eat grass, and we eat rice, vegetables and fruit — all of them come from the green factory. The leaf also gives out a gas that we need to breathe. So with every breath, we can thank the quiet workers above us. / At night, the factory rests and waits for the morning sun. In
