The article considers a complex of exercises for teaching English professional dialogue-questioning to future doctors in international groups, defines the concept of “exercise”, analyses and systematises classifications of exercises for teaching dialogic speech to students majoring in Medicine. It is indicated that the basis for the formation of English professional competence of future doctors is the teaching of dialogue-questioning, since dialogic speech prevails in the everyday communication of medical professionals. It is determined that during the formation of English professional competence it is necessary to follow the sequence of acquisition of language and speech skills. This principle is reflected in the organization and systematization of three stages during designing the complex of exercises, namely the preparatory-orientational stage, the structural-communicative stage, and the final (reflective) stage. It is also established that the context of cultures should be taken into account when designing the complex of exercises for students of international groups, divergences between high-context and low-context students at the levels of cultural, verbal, and nonverbal behaviour can lead to misunderstandings and conflicts while performing English professional dialogic speech tasks. The issue of the context of cultures has led to the designing the corresponding methodology for the complex of exercises during teaching English professional dialogue-questioning to future doctors. It takes into consideration the differences between representatives of high- and low-context cultures. An algorithm for setting tasks for high-context and low-context students has been designed. It provides a more detailed task formulation for representatives of high-context cultures in order to improve understanding of tasks by its representatives and optimize speed and quality of exercise completion. The above-noted methodology also involves placing a handout for high-context cultures after each exercise which specifies the rules of behaviour and communication when performing pair and group tasks in English for professional dialogic speech in order to avoid difficulties during the exercise preparation.Key words: English professional dialogue-questioning, dialogic speech, complex of exercises, future doctor, international group, high-context culture, low-context culture, preparatory-orientational stage, structural-communicative stage, final (reflective) stage.
