When I was
a child, I live in a small village. We don't have many toys. We did a
lot of housework. The days was very boring and tiring. So,
I hope to live in the city. Because the city is very beautiful and interesting.
And the robots will helping us do some things. Now I am living at a city,
and I miss my home very much. The air is clean
and the
mountain are green. We can played with some animals.
I think we should protect environment to make our lives happies.
I am look forward to
do some things for my hometown.
