The causes and purposes are extremely important subjective factors in the process of understanding and transforming the world. In modern Russian, there is a tendency to specify and refine the linguistic means of their expression, each of which corresponds to a rich vocabulary and syntactic constructions. However, their distinction is not clear-cut. There are both differences and similarities in the linguistic expression of these two categories. The interrogative constructions referring to causes and purposes are capable of expressing various indirect speech acts. Within Q-A unity, the ''question'' and ''answer'' about causes and purposes are influenced by numerous factors, both linguistic and extra-linguistic. This study can help deepen the understanding of these two important categories, and can better serve the teaching and learning of RFL. |
