      The British are famous as animal lovers, and in a nation of about 60 million people, there are about

 27 million pets! The most popular pets are dogs and cats.

      Many British people say that the main reason they have a pet is to keep them company (陪伴他们).

 According to a recent report, 60% of people who live on their own have a pet as company. A lot of

 pet owners treat their pet just like one of the family. Many cat owners make holes in their doors so

 their cats can come and go as they please. Dog owners spend a lot of time walking their dogs.

      Another reason to own a pet is for protection, especially dogs. Most thieves would think twice

 about breaking into (闯入) a house if they could hear a large dog barking inside. Some people choose

 their pets because of their beauty. The most beautiful animals can win prizes at pet shows!

      In the UK, some pet owners think that nothing is too good for their animal! Some people take their

 pet to the animal doctor more often than they visit their own doctor. They might even take a day off

 work to care for a pet when it is sick. Many people talk to their pets, and some talk to them over the

 telephone. And of course, they mustn't forget to celebrate the animal's birthday!
