阅读下列材料，从A、B、C、D四个选项中选出最佳答案。①At school, students usually learn many subjects in the classroom like English, math and so on. Now there is a new one in some schools—school gardening (园艺). It is an outdoor (户外) subject. In the gardening class, teachers teach students different kinds of vegetables and how to grow (种) them. Then students work in groups.
②____ Why? Because they can have much fun in this class. They don't have to sit at their desks in the classroom all day. They can get out, get their hands dirty, do things with their own (自己的) hands and relax.
③It's also fun to get something to eat and see. In some schools, students like to grow carrots and tomatoes. It's always interesting for them to get a carrot or a tomato, wash it and eat it right in the garden. In some schools, students like to grow flowers (花). When it's spring, all the flowers come out and they're really beautiful. Students like to walk and talk in the beauty. That's their favorite thing to do after busy hours of work.
④Only fun from the classes? Of course not. Students can learn something, too. Keeping a school garden is difficult and all the students in the group need to come and help. This teaches students teamwork. Also, some vegetables are easy to grow, but others need a long time. This teaches students they need to wait (等待) before they get the things they want.
⑤There may (可能) be many other good things about school gardening. But one thing is for sure—students really love having outdoor classes.
