教师组织学生们进行讲述自己种植蔬菜，花和树木的经过，教师可给学生们种植西红柿的简单过程，如：
First put some soil in a box, sow the seeds carefully, and then cover them with more soil. After that keep the box in the shade so that the sun does not burn the little plants. Later ,after a few week’s time put the little plants in the earth. Don’t forget to water them, so that the soil will not be too dry.
