Good evening, students. Today, I would like to tell you about what will I be in the next 20 years.

When I was a little boy, I wanted to be a policeman and a doctor.

Now, I know what will I be in the next 20 years. I will be a racer in the next 20 years. When I am 31 years old, I will change my job. The new job will be a fireman. Being a fireman is sometimes a very hard job because the fire bell sometime ring at 1 o’clock in the morning. When I am 39 years old, I will change my job again. The new job is a policeman who needs to get much sleep because it demands attention to catch thieves. When I am 42 years old, I will change my job again. The new job will be a doctor, it is a hard job, too. Doctor sometimes have to sleep at 11 or 12 o’clock because they try their best to look after their patients.
