小刚做了36道数学题，做错了6道，他做对了几道？

    I've learned from the newspaper that your company is looking for receptionist. I'm very interesting in the job and I'd like to apply to the position.

    First of all, allow me to introduce myself. I had just graduated from high school and taken the University Entrance Examination. I want to find out a part-time job this summer. I'm 18 year old and have a good command of English, especial in terms of speaking and listening. In fact, I once won the first prize in the English speech competition hold in our school. Besides, I'm quite easy-going but therefore very popular among my classmates.

    I sincerely hope you can give us a chance. I'm looking forward to your early reply.
