【題目】It took me three long and hard years to get a lovely little dog named Dion.

My family and I met it at a dog show. We drove for four hours to its owner’s house where she showed us three little dogs, two males and one female. They were so lovely with their little legs, long bodies and heads that looked too big for their bodies. It took me a long time to decide which one I wanted, but I finally decided when the female came up to me and licked(舔)my face.

My mother and I took Dion to a kindergarten(幼稚園)for little dogs. She was very shy and hid from people. But she was very friendly with the other dogs.

If you want to get a dog, think about your time and the work you must do. I walk Dion four to six times a day. I feed her, spend time with her and watch her when she is out of her doghouse. Even if my favourite TV program is on, or a good part in a movie is coming up, I still have to take care of her. It is a lot of work to keep her clean. Sometimes when I brush her I end up with hair all over me.

But I think it is all worth it. Dion also gives her love to me in return. She is always there to lick me and lie on me. I like playing with her. I think she can tell when I am happy, sad, angry or troubled. Dion is not only my dog, but she is also my friend.

1What does Dion look like?

A. B. C. D.

2The writer finally decided to take Dion because ________.

A. it was very clean B. it was the youngest one

C. it was very quiet D. it was friendly to him

3Paragraph 4 tells us that keeping a dog is a _____________job.

A. hard B. funny C. popular D. dirty
