       2.4.4    Read and translate the following sentences paying attention to the forms and functions of the
gerund and the verbal noun


                                                                  A
         1. Putting down his ideas on paper took Newton eighteen months. 2. We know of his having spent more than 20
years of scientific thinking before finally formulating them on paper. 3. We know of any object being prevented from
moving at constant speed by air friction. 4. We have heard of Newton’s having been suggested to put down on paper his
ideas, which he did.
                                                                   B
         1. Demonstrating the first law of motion on the Earth’s surface is rather difficult due to the tremendous forces of
gravity. 2. Newton’s having established the law of inertia has provided scientists with a means for setting satellites on
proper orbits. 3. The aim of his experimenting is increasing the speed of calculations. 4. It seemed that Newton’s only
pleasure was experimenting. 5. We know of this electrical engineer’s having designed a new type of a digital computer. 6.
The motion of this body was changed because of its having been acted upon by an external force. 7. Scientists are able to
