We’ll never forget a day when my classmates | 76．―― |
and I paid a visit a chemistry factory．It | 77．―― |
is a large one with nearly 20，000 workers．It look | 78．―― |
like a garden and we saw colorful flowers，grass and trees | 79．―― |
there．We also visited some workshop and found workers | 80．―― |
working hard．We talked to them and learned a lot of．We | 81．―― |
understood them further．On the way home we felt very tiring | 82．―― |
but we all thought we have a very good day． | 83．―― |
we really hoped what we could get more chances | 84．―― |
of leaving the school and learn about society． | 85．―― |
