Dear Mr Wang,
I’m writing to recommend Zhang Hang as our new monitor.
I think he has some strong qualities for this position. Zhang Hang is confident. He is good at making speeches. He also does well in computers.
He is hard-working, modest and organized. He often spends lots of time organizing after-school activities.
He is very helpful too. He never minds doing extra work for our class. He always tries his best to help other students. He is very popular with us.
I think Zhang Hang is the most suitable person to be our monitor.
I hope you can consider my recommendation.
Yours sincerely,
Li Ming
