Grammar: Gerund and Gerundial Constructions Like any construction the Gerundial construction consists of two elements - the nominal and the verbal one expressed by the Gerund; the nominal element can be expressed in three ways: By a possessive pronoun. It resulted in his being arrested. By a noun in the Possessive case. I insist on our customer's being invited to this discussion. By a noun in the Common case. Einstein being rewarded the Nobel price soon became widely known. Вскоре стало широко известно, что Эйнштейн награжден Нобелевской премией. I hate animals being treated cruelly. Я ненавижу, когда с животными жестоко обращаются.
There are cases where the nominal element must be expressed by a noun in the common case: When the nominal element is expressed by two or more nouns. I insist on Kassenov and Omarov joining our group. When the nominal element has an attribute in postposition: He insisted on all Russian prisoners of war being returned to their motherland. When the nominal element is expressed by a noun denoting a lifeless thing: The captain insisted on the boat being unloaded at once. When the nominal element is expressed by a pronoun that is not possessive. I hope I can reply on everything being done in a proper way.
