[20points]英文好的朋友~幫忙改文ar~thanks

This news reminded me that "Fei Fei" had passed away one year ago. Sum Tin-ha was a very important person because she contributed a lot to the society; and she was very optimistic. Joyce Cheng Yan-yee said "I remember mum always called me sum gon [sweetheart]. We had this secret code – she would say "sum" and I would say "gon". But I won't hear that from her any more."This might just be a little thing between them, but I think it is very touching. When Sum Tin-ha died, Joyce was only around 20 years old; but she was brave enough to step up and confront the reporters. Thus, she had done a great job in her mother's funeral and her behavior was appreciated by many people.

The world economy is bad now. In my opinion, it is reasonable for Asia Television to lay off 300 staff because they are not a charitable organization and they are suppposed to do whatever they can to ease their financial problems. On the other hand, I hope the situation is getting better. Since Hong Kong is an international city, we should always keep the spirit of self-strengthening inside us.

This news is about a 15 years old boy died in a car accident. He was hit by a car when he was walking down the road and he died a day after the unfortunate accident. Talking about car accidents, on Thursday night, a boy was trod under a Passat saloon car in Vauxhall . The county police service hall spokesperson, Sang Biya, promised not to publicize the name of the boy. The police are seeking eyewitnesses right now and they demand more detailed information. After I saw this news, I became more aware that we must be careful when we drive or walk. Moreover I have a suggestion - the government should revise the traffic regulation and come up with stricter rules to remind people to drive and walk carefully. I hope the situation will then be improved.
