measure the forces of gravitation at any point on the Earth’s surface due to Newton’s having provided them with the second
law of motion. 8. Having proved the validity of his theory, he went on working at it.

         2.4.5     Analyse and translate the following sentences. State the function of the gerund and gerund phases


         1. Original scientific thinking is very important for every researcher. 2. Many scientific discoveries preceded
Newton’s stating his laws of motion. 3. Newton’s having stated his laws of motion is very important for modern science. 4.
Without proper understanding the major laws of mechanics it is difficult for the students to take part in research. 5. On
receiving wrong results one must repeat the experiment. 6. By studying Newton’s laws of motion we learn that they are
applied not only in engineering but in our daily life as well. 7. While Newton was studying at Cambridge his favourite work
was experimenting. 8. On his friend’s advice Newton started putting down on paper the results of his original scientific
thinking. 9. The Principia’s having been written in such a short time was due to its author’s great previous work. 10.
Newton was interested in making experiments since he was a student at Cambridge. 11. Newton’s having invented the
mathematical machinery needed for proving the validity of the basic laws of mechanics was of great importance. 12. The
Principia’s having been published brought Newton world fame. 13. On being set on a proper orbit completely free from the
Earth’s gravitation a satellite keeps on moving forward through space. 14. Successful travelling of satellites depends on
their having been set on a proper orbit. 15. There is a constant danger for every spaceship of being burned up because of its
having been set on a wrong orbit. 16. The second law of motion provides scientists with a means for measuring forces,
which is of great importance in planning the orbits for artificial satellites. 17. There are two ways of stating the third law of
motion. 18. Jet engines on account of their being air–breathers require an air supply from the atmosphere for feeding the hot
gases. 19. The state of rest or uniform motion of a body is changed after its being acted upon by some external unbalanced
force. 20. By repeating experiments one gets more data which help arriving at right conclusion.

          At the physics laboratory
          The physics lab of our University occupies several large rooms. In each room there stand laboratory benches. There
is enough space in between the benches to allow several students to do experiments with various apparatuses and gauges,
such as ampermeters, voltmeters, potentiometers, condensers, transformers, rheostats, oscillographs, etc.
          Let us follow a group of freshmen who are going to have their first lecture on physics. In the lab they see lab
technicians who are busy arranging some apparatuses on the demonstration table. The teacher is drawing a scheme on the
blackboard fixed against the wall behind the lecture table.
          As the students enter the lab the teacher turns round and greets them.
          Teacher: All right. Left’s begin. Today I am going to give you an introductory talk. First of all, while
experimenting, you must be careful with electrical apparatuses. Don’t switch them on before you are instructed how to
handle them properly. Wrong handling may cause either failure of the unit, or injury to human life, or both. Any
carelessness may bring about an accident. There are certain rules of handling the electrical equipment and they should be
strictly observed. So be attentive and careful!
          A student: Certainly, we shall observe all the rules. We promise neither to break the rules nor the apparatuses.
          Teacher: All right. Today’s talk is devoted to the discussion of a fundamental physical principle governing the
motion of an artificial satellite. To begin with, let’s try a most primitive experiment. Watch it! Here is a small weight
fastened to a string. Now, I’m swinging the weight in a circular orbit, letting the string wind up on my finger. Watching the
