判断二进制数的10011转换成是十进制数（）。 A．15 B．11 C．13 D．1

I really love my job because I enjoy working with small children and like the challenges and awards from the job. I also think my work is important. I wasn’t an excellent student because I didn’t do much schoolwork. In my final term I started thinking what I might do and found I didn’t have much to offer.

I then found myself a job, looking after two little girls. It wasn’t too bad at first. But the problems began when I agreed to live in. I would be there if my boss had to go out for business in the evening. We agreed that if I had to work extra hours one week, she’d give me time off the next. But unluckily, it didn’t often work out. I was getting very tired. Because I had too many late nights and early mornings with the children.

One Sunday, I was in the park with the children, and met Megan who used to go to school with me. I told her about my situation. She suggested that I should do a course and get a qualification（资格证书）if I wanted to work with children. I didn’t think I would be accepted because I didn’t take many exams in school. She asked me to phone the local college and they were really helpful. My experience counted for a lot and I got on a part-time course. I had to leave my job with the family, and got work helping out at a kindergarten.

Now I’ve got a full-time job there. I shall always be thankful to Megan. I wish I had known earlier that I could have a success, even if I am not top of the class at school.
