*Hi, I exceeded the 5000 characters limitation so I will submit the rest in the next post 

Dear Sir/Madam, Whom it may concern

I am writing to express my deep concern in connection with the news about in regard to the Beijing International Airport’s redevelopment plan which is was reported in Beijing Daily(italicized) yesterday. I am Guangyu, and for more than 10 years, I have been living in Dongheng residence for more than ten years, which is only 5 kilometers away from the airport.

Airplanes could cause numerous noises during taking off takeoff and landing. Especially in the at night, the noise hinders me from sleeping that sometimes I could not can not fall asleep there were some times that I could not sleep until the traffic at the airport slows down around 1:00 or 2:00 am. is air traffic is lighten somehow. As far as I know, most people who live in our my neighbourhood are suffering from the same problem as mine. Secondly, In addition to the noise problem, there are  the redevelopment of the airport would also cause heavy traffic jams in on the highway which connects the airport to the city centre er in the morning and evening. It will take cost us me and my neighbors an extra one hour to struggle to go to the office or go home. in our daily commute.

Please help me to correct this writing, thank you.

1) 'Is' is the present tense. It was reported yesterday, so it needs to be 'was' which is the past tense.

2) This needs to be either 'numerous noises' if you mean a large number of individual noises, or 'excessive noise' if you mean just too much noise in general.

3) In is acceptable, but during would be used here by native speakers.

4) This is a part of a conjoined sentence, so it does not need to be capitalized.

5)This is an ongoing problem, so you would say 'sometimes I cannot fall asleep...' and it should be finished as 'the air traffic is lighter' as you are comparing the traffic at 1-2 in the morning to the traffic from earlier. '-er' is comparative suffix.

6) This would more commonly be 'me', but I'm not sure if 'mine' is technically correct or not.

7) Secondly should only be used if there has been a 'Firstly' somewhere in the preceding text.

8) This requires the indefinite article 'an'.

Part II

I understand that airplane could brings us lots of  much convenience and helps us save time, but living in such a noisy environment can really cause much harm to our health, such as hearing or nervous system  nerve-related diseases problems. What I am worrying about makes me worried is that the redevelopment plan of the airport could make the worsen the environment around the airport situation even worse, so I object this plan.

Before the government takes makes any further decision, I suggest that a comprehensive environmental affection research must  be done in advance regarding the influence the redeveloped airport would have on its surroundings. And I think it is a responsibility of the media to appeal to the government to make more efforts and measures put more effort in to let our making our living environment better and better.

Thanks and I looking forward to your response. hearing from you.

Yours Faithfully,
Guangyu
