      St.: For ihe system to operate one should control the temperature
         carefully.
      1. What do we have to do for the hypothesis to be confirmed?
         (to perform a series of experiments)
      2. What must she do for the article to be published? (to put it in
         order)
      3. What do they have to do for the procedure to be simplified?
         (to leave out unnecessary details)
      4. What do we have to do for the experiment to consume less
         time? (to simplify its technique)
      5. What did they decide to do for the problem to be solved? (to
         divide it into two steps)
      6. What did experimenters do for this problem to be avoided? (to
         use an ingenious scheme)
      7. What will they do for the scheme to be made use of? (to
         refine it)
VI. Translate into Russian paying attention to different functions of
    the Inifinitive and its constructions. (see the key on page 88)
    1. The betatron is used to accelerate electrons to energies of tens
       of millions of volts, or even to hundreds of millions of volts.
    2. In order to write Newton’s laws in vector form, we have to
       define the acceleration. Molecular forces have never been
       satisfactorily explained on a basis of classical physics; it takes
       quantum mechanics to understand them fully.
    3. Although the resonant cavity we have been describing seems
       to be quite different from the ordinary resonant circuit consisting
       of an inductance and a capacitor, the two resonant systems
       are, of course, closely related.
    4. Most of present-day research in molecular biology is an attempt
       to figure out the shapes of complex organic molecules.
    5. Quadrapole lenses are used to form and control beams of
       particles in much the same way That optical lenses are used
       for light beams.
    6. To get the electric field completely for all distances, we need
       to solve for the electrostatic potential.
    7. Unlike the electrical effect in matter, which always causes dielectrics
       to be attracted, these are two signs to the magnetic effect.
