Having read about your newspaper's decision to start a campaign for protecting the environment,     1    . I decided to write you this letter.

The state of our parks is very shocking, with rubbish everywhere.     2    . I used to find a trip to the park very relaxing. Upon the arrival of spring, beautiful birds would sing happily in the park. I enjoyed this very much. However, now I just find it tiring because    3    .我不得不捡拾垃圾 where I am going to sit. The grass is covered in plastic bags and food.    4    .我很难过 that the young people of today do not clean up after themselves before they leave the park.     5    . There are so many interesting animals and insects living in our parks. It would be a shame if they were destroyed because of people's activities there.

Yours,

Wang Qiang
