根据这封信的内容,完成下面任务。

Dear editor

  I live in a beautiful city.  Many visitors come to my city.  There are so many

colourful peacocks (孔雀) here.The peacocks mostly live on the grass Land of

Dongfeng Square. They are given food freely by visitors. They usually  throw

food to them,  and don't think about at all whether the food is right or not.  Some

of the peacocks became ill, some even died after eating the bad food given by the

visitors. I'm sure most of the visitors who throw food to the peacocks really like

the birds, but they don't realize (意识到) that they may be doing them harm

(伤害). The visitors should be told what they have done is very harmful to the

birds, and this kind of thing must be stopped from happening.

  Perhaps we can build some small shops beside Dongfeng Square to sell

peacock food. It's our duty to give more love to these beautiful birds and to look

after them carefully.

Yours

Sun Yan
