✔ 最佳答案
You can learn some more "phrases" and "idioms", replacing the vocabularies, that can lengthen your composition.
For example, you can say "As for my personally opinion" instead of "I think". Or else, use more idioms, putting "put your legs into others' shoes" before "think on others' side."
But of coz, the content of the composition is the most important thing of a passage.
