Before starting this topic, get a sense of the extent to which students use email and English either at work or in their personal lives. Busy teachers have submitted 25 worksheets on this topic. You can use this worksheet in a lesson about polite business letters for your adult upper-intermediate students. A thorough introduction of the topic and key vocabulary would be necessary before attempting this assignment. In the first section, students have to rearrange words to form accurate sentences while in the second section, students rewrite a business letter in a more formal and polite way.
