题目内容：

Today I took Frank to have a training class(培训课). We got there earlier than most of the other dogs and owners.

Mr. Brown helped us teach our dogs some skills(本领). When the dog did it, he said, “Good dog！” He was a serious man but he laughed a lot with dogs. He said Frank was smarter than other dogs.

Next to Frank was also a smart dog. His name was Sam. His short legs made him look funny, but he could run faster than many of the bigger dogs. His owner was a quiet girl and looked a little shy. So I said hello to her first. I hoped she could be my friend.

At the end of the class, Mr. Brown told me that Frank did the best this class and he would give him a ball.
