短文改错：

Dear Mr. Smith,

I am writing to express my concern about the noise pollution from the construction site near my house. The noise has been affecting my daily life since the construction started several months ago. I cannot concentrate on my work or even have a good sleep at night. I have tried to talk to the construction workers and the site manager, but they seem to ignore my complaints.

I would like to request that the construction company takes immediate action to reduce the noise pollution. I suggest that they use noise barriers and restrict the working hours to a reasonable time. I hope that the company can take my request seriously and make efforts to improve the situation.

Thank you for your attention to this matter.

Yours sincerely,

Li Ming
