    When I was very young, I wanted to become a veterinarian (兽医) one day, because I loved animals very much, especially dogs. But it was a pity that there was no room in my adult life for a dog. Then, last year, I could not believe that I developed cancer (癌症). I wanted to keep a dog, but I knew my illness made it impossible for me to keep one. In early September to my surprise, my doctor told me that I could keep a pet as my friend, because my immune system (免疫系统) was strong to keep a pet.

The same day I went to an animal market with my friends. When I saw a 9-week-old dog with big brown eyes, nice ears and white fur all over the body, I took him home. I called him Oscar. I’m happy these days since Oscar came into my life. My new favourite pastime is to watch him sleep, eat and run. And I have been spending more time caring about him, taking long walks with him in the park.

Now I still have the physical (身体的) examination once a week at the hospital. But my illness has taken a turn for the better with the company (陪伴) of a dog. My immune system getting stronger, my doctor tells me. Thanks to Oscar, my life has changed a lot.
