     I suppose that having been brought up in the countryside and close  to animals,it wasn't remarkable

(不平常的)when I decided  to become a vet(兽医). Luckily I was also good at all the necessary science

subjects. So after the college entrance examination I found myself at a veterinary college,training to look

after animals in all kinds of situations. I hoped that I would be able to work in the research field so that I

could find cures for animal diseases.

      Much to my surprise,I found public health care was a very important aspect of my course. This is an

area of animal medicine where a vet's work has many things in common with the work of a doctor of

human diseases. I particularly liked it because I recognized that the study of animal diseases can help

human medicine. As we know,many infectious diseases come from animals-including SARS and bird flu.

Some of the infections have only been understood after carefully analytical work in labs by animal doctors. They helped identify the animal source for diseases such as SARS. They were also the first to identify

various kinds of viruses. Sometimes vets are also able to suggest a cure for human illnesses. When I found this out I was determined to make public health medicine my chosen career.

      After graduation,I applied for a job in public health. Soon I found myself concerned with the problem

of bird flu. This is  an illness that attacks birds,but humans can catch the disease  if they are in close

contact with infected birds. Though the job  is dangerous,it makes me proud that vets and other animal  

disease researchers are in the front line helping to fight these  unknown human diseases.
