Giup minh giai bai tap nay voi minh cam on

Dear Mr.Smith
1. I'm writing to complain about the dirt and smoke come from your factory's chimneys
2. Two days ago I decided to do my washing
3. I washed the sheets and put them out to dry because it was a nice sunny day, there was a breeze
4. When I took washing in, I was horrified to discover that it was covered in dirty marks
5. I assume that the breeze I mentioned carried the dirt from your chimneys.
6. Until this accident, I thought your chimneys were safe and clean.
7. I suggest that your factory should fit the new filters to its chimneys as the dirt and smoke are dangerous
8. I look forward to receiving your reply
YOUR SINCERELY
Mrs. Jane Hunter
