Dear Zhang Li,
I have been so sad these days. As you know, an earthquake happened in my hometown and both my parents died. Though the government gives us much help, my little sister and I cried every night because of missing, and I don’t want to learn anything. I find it hard to talk with the people around. Life is dark for me without parents’ love!
What should I do? I really need your help.
Yours,
Lin Na

Dear Lin Na,
I'm so sorry to hear the sad news.
I understand you .
