Many teachers watch and listen while speaking activities are taking place. They note down things that seemed to 【B1】______ well and times when students couldn’’t make themselves 【B2】______ or made important mistakes. When the activity has finished, they 【B3】______ ask the students how they thought it before giving their own feedback. They may say that they liked the way Student A said this and the 【B4】______ Student B was able to disagree 【B5】______ her. They will then say that they did hear one or two mistakes and they can then either discuss them with the class, write them on the board 【B6】______ give them individually to the students 【B7】______. In each case, they will ask the students to see if they can 【B8】______ the problem and correct it.

Of course, there are no hard and fast rules about 【B12】______. Some teachers who have a 【B13】______ relationship with their students can 【B14】______ appropriately during a speaking activity 【B15】______ they do it in a 【B16】______ non-obtrusive (谨慎的)way.
