I need two tasks to be done - Type One, which is also called a PR task, is to write a short oral passage at around 240 words. Usually the opening and ending of the short passage is already given, and need only a little modification. The major task lies in writing the main body, which is around 140 words in length.
Type Two, which is also called a MO task, is to add or delete a few details on the basis of previous passages to make it conform to the requirements of new customers. You will need to make sure the logic of the new passage is consistent.
