Warming up

In SB1(下) Unit19, we have learned some knowledge about agriculture. And we have known about one of the greatest scientists in our history-Jia Sixie.

Did you remember? How do we plant crops?

We should plant rice in a field one year and wheat in the field next year.

How do we plough?

Plough deep the first time and less deep the second time.

In this unit, we will learn about scientists who are important to the history of botany and agriculture.

This word “botany”植物学,is a word about plants. As we all know, there are many plants around us, such as wheat, corn, tomato, apple trees etc. Without these plants, we can’t live. But how much do you know about them? Who can tell us something about them.

Student A  Wheat is a kind of plant that can be make into bread, some delicious cakes which can make us full.

Student B  Apple trees can produce apples that can provide us vitamins which can keep our bodies fit.

Yes, these plants are very useful, but how do we plant them? Where are they from?

It is a kind of very careful work to plant the crops and trees.
