Do you have a vegetable garden? Have you ever watched a seed (种子) sprout (发芽), grow and fruit until it became the tomato on your plate? If you go to school in the US, there’s a good chance you have.

At the moment, nearly 20 percent of schools in the US have their own vegetable gardens that are planted and cared for by students. Next year, even more schools will have gardens and more US kids will know the pleasure of growing their own food.

Much of the growing interest in planting comes from First Lady Michelle Obama’s “Let’s Move” project, which started last year. The First Lady wants to improve children’s nutrition (营养) in the US — and she began her project by planting a garden at the White House with the help of some local kids. The kids were more interested in eating the vegetables from their garden than in eating fast food. This gave the First Lady an idea.

Because so many US kids eat breakfast and lunch at school, the food should be healthy and good. Why not let kids grow the food for their own cafeterias (食堂)? Mrs .Obama’s plan gives money to schools to start their own gardens, and more school gardens are sprouting up every day.

Students also use the information from their gardens to study science and math, and they paint pictures of their gardens in art class. Many students choose to work in the garden instead of playing on the playground during their noon break. Sound like fun? Ask your teacher if there’s room for a garden at your school, too.
