Last weekend my sister went to the supermarket to buy some groceries. Three hours

ago, with full bags of goods in both hands, she headed for /\nearby bus stop, tired and 
later                                           a/the
hungry. She was waiting for the bus while it began to rain. After what seemed ages, 
                            when
came a bus, crowded of passengers. When it was her turn to getting on the bus,
                with                             get
someone said, “ Sorry, no more rooms.” Quite disappointed, my sister had to take a 
                          room
taxi. Half way home, however, the taxi broke out. Hardly had he got out of the taxi 
                                    down       she
when a bus passed by. It was empty, but she had been missed it! What an unluckily 
                              去掉she               unlucky
day!

One possible version:
Dear Mr. Wood,
　　　How are you doing these days? 
　　　Although it has been a year since I came back to China, I still relive the thirty thrilling and fascinating days once in a while. I know without your kindness and sincerity, my stay back then would have been quite different. It is you who have opened a new world to me. Never had I known a language could be taught and learnt that way, which, up to this day, remains a guide to my English learning.
　　　By the way, I was wondering if I could have your new address and phone number. My friend, Wang Lei, is going to apply for your school this summer. Would you mind if he asked you for more details? 
　　　All the best wishes! 
　　
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Yours,
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Li Hua
