3.More limitations are likely to exist on the freedom to change the input and output, that on the freedom to modify processing methods.

4.We expect a computer to work for at least several hours without a fault.

5.A machine which carried out its internal arithmetic in binary notation is likely to be especially suitable for scientific and mathematical applications.

6.The result of a computation is said to involve error if the result differs by only a small percentage from the solution.

7.These experiments are likely to throw some light on this complicated problem.

8.This hypothesis has been found to disagree with experimental evidence.

9.The relativity theory appeared to be a turning point in physical thinking.

10.Lasers have proved to be indispensable in many fields of research.

11.Electronic equipment is likely to find an over growing applications.

12.Hot springs are believed often to be due to the presence of magma near the surface.

13.The atmosphere has been proved to extend several hundred kilometers above earth.

14.Rutherford began a series of investigations of radioactive elements which were known to disintegrate, and showed that the radiations emitted were of three kinds.

15.The radiation spectra have been shown by previous studies to be quite complex.

Complex Object

1.We didn’t want anybody to stop the experiment.

2.Everybody noticed him to be proud of the results received.

3.The authorities of the company expect the contract to be signed immediately.

4.I heard his name to be mentioned among the members of the students’ research team.

1.For such data to find application in further work their validity must be left in no doubt.

2.For the long-term experiments to be realizable various aspects of the problem must be taken into account

3.For such suggestions to be of practical use they must be based on observation and experience.

4.For this method to become applicable to our experiment the following alterations should be made.

5.The suggestion is both attractive and interesting but the work is not sufficiently advanced for any definite opinion of its validity to be formed.
