dear editor,
i’ve just read an article in a newspaper about saving tigers. it says that the number of tigers is becoming smaller in our country. it’s terrible.                                            
[例文]
i saw a few people sell bones of tigers by the roadside the other day. i also learned that some people killed tigers in order to make money. and too many trees have been cut down. the places where tigers used to live were destroyed. tigers are in danger of dying out.
our government should punish the hunters. we should try our best to make our earth pleasant and peaceful, not only for human beings but also for animals.
