Have you ever been to London? 1 do you know about London? Now let me tell you.

    Greater London has more than 8,700,000 2. From the year 1801 to the early 20th century, London was the biggest 3 in the world. But now many cities are even 4 than London.

    London is famous for many things. Tourists come from all over the world to visit its famous buildings and 5 the famous clock, Big Ben. 6 many big cities, London has 7such as traffic jams and pollution, and they 8 the city from developing. Every day people come and go by underground, 9 there are still too many cars and buses in the streets. So the air isn't clean. However, it is cleaner than it was 100 years ago.

    For me, the 10 things in London are the parks. There are many parks in the city centre. But my children's favourite place is Hamleys, the biggest toy shop in the world.

    My guide dog, Amelia, has been with me for more than three years. She has given me courage to enjoy life.

    My most difficult time was when I knew" I got cancer(癌症). Amelia was there for me all the way. She helped me beat(打败) the illness. For seven weeks, I had to have radiation therapy（放射） five days a week. Each time we arrived in front of the hospital, Amelia knew where we were. All I had to say was: Amelia, take Mommy to the room. After a few trips, honestly, I even didn't need to tell her which room we had to get into. She knew the way. Without Amelia's help, I would not have the courage to go through the hardest time.

    Today our journey still goes on with fun and happiness. In the past few years, we have visited many places and have met many wonderful people. To me, Amelia is not only a dog but a family member. She always brings me happiness and I love her so much.

Last summer, Tom and I    in China.
