书面表达。
请用英语写一篇小短文，说出你最不喜欢哪种不文明的行为。为什么？如果这样的事情发生了，
你会怎么做？如果别人不听你的劝告，你又会怎么办？（80词）
I often see some impolite behaviors in public places. I feel very bad when someone draws anywhere
and drops litter in public places. I also get annoyed. If that happens, I will say politely, "Excuse me, would
you mind not doing that? It's not good for our environment." I think if I meet impolite people in the future,
maybe I should try not to be so polite to them.
(答案不唯一)
