My dear WWF,

I’m sorry that I report my feelings. Chinese Yangtze alligators ( 扬子鳄 ) in my area faces extinction. We, natives, are struggling to help them. We plan to stop factories nearby polluting the river to give them a safe habitat. We are also ready to offer them more food. Do you think our plans practical?

Look forward to your reply.

Best wishes.

Yours,

Dear WWF,

My dear Johnson,

I need your help. The people in my town are interested in catching birds recently. These birds are caught to be sold. We are afraid of the future of the birds. I am going to suggest the mayor that we should make some laws to teach the catchers a lesson. Do you think it is a good plan? I hope you can give us some more ideas as a good lawyer.

Yours sincerely,

Angela
