Не спец в . я бы так выполнил это . 1) t he first metro line had been constructed (by workers) by may 19352) two districts were  connected with t he first line3) the construction work was done (by  moscow metro builders)   in difficult geological conditions4) the work was  continued  during the great patriotic war5)  18 districts of the capital are linked with t he belt line6) trains are conducted with an automatic driver  according to the schedule7) the streets of the city are decorated    with flags, portraits, flowers and garlands of coloured bulbs b efore holidays  8)  an automatic driver was  successfully tested (в последнем предложении не буквальный переход, а по смыслу. "has undergone"   - само по себе с пассивным значением, хотя формально это активный залог. это ощущается и в языке: автопилот(автомашинист) подвергся успешно испытаниям  (прошел успешно испытания). поэтому формальное обращение будет выглядеть странно: successful tests have been undergone with an automatic driver)
