III. GRAMMAR REVIEW

Task 1. Transform the verb in the sentence from Active into

Passive Voice. Mind the word-order and the tense of the verb.

1. Engineers require distance measurement to set out the position
of a point in construction work.
2. GPS will provide inter-point distances over any distance

without the need for inter visibility.
3. Surveyors have used subtense bar to measure distances by
means of direct comparison.
4. Modern EDMI are now displaying distances in digital form.

5. We can attach electronic calculators to EDM to compute
additional setting out data.
6. Dr. T.L.Wadley invented a micro-wave instrument, called

tellurometer.
7. People use infrared wave instruments for most of the civil
engineering works.
8. Scientists developed the first light wave instrument in Sweden.

Task 2. Fill in the proper preposition. There two extra

prepositions that you don’t need.

On, to, upon, out, on, of , for, out , at, in

1. EDMI will measure slope distances but depending ___ the
model they could be made to compute horizontal distances,
differences in height, co-ordinate differences, etc., by inputting
vertical and/or horizontal angles.

2. Sun light or artificially generated electromagnetic wave
consists ___ waves of different lengths
3. Microwaves, infrared waves and visible light waves are useful

___ the distance measurement
4. Light Wave Instruments rely ___ propagation of modulated
light waves.
5. Distance is required to set ___ the position of a point in

construction work.
6. The method used for any particular job depends ___ the cost
and the availability of the equipment for example.

7. Distance measurement can not be carried ___ if there are
rivers, lakes, hillocks or ravines along the survey lines.
