Yesterday there was a discussion ,whose theme was "Shall we keep animals" in our class.From the discussion we can draw the following conclusion:On one hand,in 20 students' eyes,animals should be kept at zoo so that people can see different kinds of animals at zoo.On the other hand,30 held the contraty because animals closed in the cages can't move freely.
差不多就这样吧,你看看会不会有什么错的,稍微改改就行了
