My question deals with inversion. As is known, inversion can be grammatical and emphatic. The former is obligatory and is used, for example, in questions, e.g. Must I do it now? The latter is regarded as a stylistic device and serves as an alternative to the standard word order, e.g. I know little about it. -- Little do I know about it.
Teaching grammatical inversion is something we know quite well because we deal with it from the very beginning. The problem is emphatic inversion, which is usually taught to advanced students, and from what I was able to find out in grammar textbooks, is not methodologically worked out.
It is either translating from students' mother tongue or mechanically converting sentences with the standard word order to sentences with an inverted word order, without any understanding of the purposes of all those manipulations.
As a result, not knowing what it is all about, students get bored, confused and often apply inversion inadequately (like, 'In vain did I try to do this exercise yesterday', after which the class howls with laughter).
I would appreciate it if you could suggest some interesting and efficient method for teaching this grammar topic.
