2. The phenomenon concerned is difficult to explain.

3. We have to consider all the factors involved.

4. The complexity of the technique involved increased considerably.

5. None of the authors concerned had based his experiment on the method

discussed.

2. Identify the participles in the function of adverbial modifiers. Give

Russian equivalents as shown in the following examples

A) Examples:

– Testing the new device, scientists used…

1. Recognizing the problem the scientist makes the first step to its solution.

2. Being separated from the sun by vacuum the earth receives its heat by

radiation.

3. Having been seen in action the device was greatly modified.

4. The scientist is often interested in a problem, disintegrating possible

consequences of its solution.

5. Every new idea is immediately taken up and developed further, forming

the initial point of an avalanche-like process.

6. Having been tested the new equipment was installed in the laboratories.

7. Having changed the traditional approach, they succeeded in solving the

problem.

8. Using radioactive isotopes, biologists are able to carry out new kinds of

research.

9. Being influenced by temperature and pressure, the volume of any

substance is not constant.

10. Having alloyed copper with tin Greeks and Romans formed a new alloy

called “bronze”.

B) Example: (When/While) Working at the laboratory he made many

experiments.

– Работая в лаборатории, он провел много экспе-

– Когда он работал….

– При работе…

1. While designing new kinds of experiments we don’t have to bear in mind

the advantages of previous ones.

2. When dealing with gases it is common practice to consider them under a

pressure of the atmosphere.

3. Calculating the weight of a body we have to multiply its specific gravity

by its volume.

4. When studying a compound we have to know the chemical formulae and

the valences of the elements involved.

5. Travelling in a curved path around the Earth, the Moon is continually

changing the direction of its velocity.

C) Examples:

– When/While heated all substances expand.

a) Нагреваясь, все вещества расширяются.

b) Когда вещества нагревают, все они расширяются.

c) При нагревании все вещества расширяются.

d) Будучи нагретыми, все вещества расширяются.
