　　At first I couldn't believe it! There were no 1 in rows; no bells rang; no one had to go to 2 . Athough we all lived“in”, 3 made us go to bed at a certain time; there was no“lights out”.

　　The 4 thing was that practically all the students went to class, 5 very few people stayed up late at night. Only the new people stayed up or missed class. The new ones always went wild 6 , but this never lasted long. The freedom took some getting used to. Our teachers treated us like 7 ; never did we have to 8 “stand up”,“sit down”,“speak out”.I don't 9 one student who didn't try his beat.

Then in winter we each studied a few 13 think about what we had grown. In maths the students built three different kinds of storerooms—small ones 14 , but usable.

I can't stand it! Besides, I could do the basic things with numbers. That's 17 !

　　So I think I am a 18 person for having gone to the school. I can read and write as well as anyone else my age, and I can think better. That's probably a real big 19 between the free school and regular school—the amount of 20 .
