When you use reported speech, you either report: statements, questions, requests /
Direct speech
Reported speech
(no backshift)
He says, “The tuner is
connected to the detector”.
He says that the tuner is connected to the detector.
(backshift)
He said, “They will use a
two-hundred-and-twenty­kilohm resistor”.
He said that they would use a two-hundred-and­twenty-kilohm resistor.
commands, other types of sentences.
Reporting statements. When transforming statements, make sure you know what
you have to change (pronouns, tense, place and time expressions).
As for pronouns, you often have to change the pronoun depending on who says what, e.g.: She says, “We compile this electronic device of common basic units”. – She says that they compile that electronic device of common basic units.
As for tenses, if the sentence starts in the present, there is no backshift of tenses in reported speech. If the sentence starts in the past, there is often backshift of tenses in reported speech.
Do not change the tense if the introductory clause is in the present tense (e g.: He says). Note, however, that you might have to change the form of the present tense verb (3rd person singular), e.g.: He says, “I use a two-hundred-and-twenty-kilohm resistor”. – He says that he uses a two-hundred-and-twenty-kilohm resistor. You must change the tense if the introductory clause is in the past tense (e.g.: He said).

Exercises
Ex. 1. Transform the following sentences using the rules of reported speech and the models “They say…” and “They said…”.
1. Engineers and technicians usually connect an ohmmeter in a circuit with the meter set for the highest resistance range first. 2. Have you ever pulled out an old store receipt and found that it was washed-out or blank? 3. Which of the following is a serial­access medium? 4. All the electrons might be removed from an atom, leaving only the nucleus. 5. How might this problem be resolved? 6. Have you used orange bug lights when camping to keep the flying pests from coming around at night, or those UV devices that attract bugs and then zap them? 7. How will a robot be able to feel something and transmit these impulses to the human brain? 8. An ohmmeter must be calibrated at the factory where it is made, or in an electronics lab. 9. How can this sense of texture be realistically transmitted to the human brain? 10. It also eliminates the possibility that the meter sensitivity will change in case the strength of the permanent magnet deteriorates. 11.
Would that begin to approach the level of sophistication in your body’s nervous system?
12. It works well when the value of the quantity does not change often or fast. 13. Is the human brain nothing more than an amazingly complicated digital switching network? 14. The compass needle will not give a clear deflection. 15. This resistor must be capable of carrying the current without burning up. 16. That means their values must actually be what the manufacturer claims they are. 17. For each meter scale, take down the number that the
44
pointer has most recently passed. 18. Then refer to it frequently in the future, especially when you see a symbol you don’t remember or recognize. 19. Write down the rest as you go. 20. There are some situations in which a digital meter is a disadvantage. 21. The amplifier volume should be kept down so that the meter doesn’t go past the zero mark and into the red range. 22. Each electron flows only a short distance before transferring its energy to another, and another, and so on around a circuit, eventually leading back to the source. 23. Electric current in a wire, measured in amperes, is the simultaneous motion in the same direction of enumerable electrons. 24. The first function of the transmission system is to use “step-up transformers” to raise the voltage produced by the electricity generator, typically about 20,000 volts, to the levels required for long-distance transport, which is generally 230,000 volts or greater. 25. Energy is the elemental force upon which all civilizations are built, and technology provides the means to harness that energy.
Ex. 2. Transform the sentences back into the direct speech.
1. He explained that an element might be both an ion and an isotope different from the usual isotope. 2. He told us that we might think of it as a positive ion. 3. She said that meters with a scale and pointer were known as analog meters. 4. He mentioned that it had extremely high input resistance, along with good sensitivity and amplification. 5. We said that the spark might jump an inch, 2 inches, or even 6 inches. 6. I told him that the resistor would draw half the current. 7. The teacher asked what the resulting atomic weight was. 8. He asked if we had noticed any strange things about the notation yet. 9. I asked whether they had heard the terms “power” and “energy” used interchangeably. 10. He said that that kept the diagram neat and easy to read. 11. She mentioned that sometimes it was desirable to have an ammeter that would allow for a wide range of current measurements. 12. You asked me what the conductance of a span of the wire that was 3 km long was. 13. He asked how much power that represented. 14. The teacher said that Lomonosov organized the first chemical laboratory in our country. 15. He said that by means of a transformer we could change current.

3.8 The non-finite forms of the verb
Participle I
Active
Passive
Indefinite
doing
being done
Perfect
having done
having been done
Participle II
done, compiled, broken,
formed, etc.
3.8.1 The participle. The absolute participial constructions
English verbs have two participles: participle I (denoting, writing) and participle II (denoted, written). Participles have some qualities of adjectives and are used as attributes in a sentence (a working device; broken relay).
A participle construction, that is, a participle together with the words closely connected with it, can function as an attribute (the symbol representing a wire, the applied voltage) or as an adverbial modifier (the relay being broken we couldn’t start the device).
Forms of the participle
Depending on the function in the sentence, on the context and meaning, English participles are translated into Russian as participles, as adjectives, as adverbial participles, as verbs.
Participles in constructions with complex object. In sentences like “I saw the batteries being recharged. I found the resistor working.” the constructions “the batteries being recharged, the resistor working” are often called “complex object in Russian grammar materials. Participle I is used in constructions with complex object after the verbs of sense perception “hear, see, watch, observe, notice, feel to indicate the action in progress.
Absolute participial construction. The absolute participial construction has its own subject (to which the action expressed by the participle refers) and can stand at the
46
beginning or at the end of the sentence. Sometimes the preposition with introduces an absolute participle clause. Absolute participial constructions are often used in literary works and scientific writing, but are rare in ordinary speech, e.g.: The conditions allowing, we started the project earlier. Nobody knowing what to do, we decided to do nothing. Two of the electricians headed toward the directors office, the other three staying in the hall. Our work finished, we left. He listened to our repair plan quietly, with his eyes closed and his face impassive.
Exercises
Ex. 1. Copy the sentences below and underline participles. Say what forms of participles are used. Translate the examples into Russian in writing.
1. Having made a number of tests, the researcher got some useful results. 2. The data obtained formed the basis for further activity. 3. The measures discussed are to be used for determining the faults in the conducting wires. 4. Being a semiconductor, germanium is widely used in transistors. 5. Decelerating trains and descending elevators use negative, or braking torque. 6. Having been impregnated, paper is used as resistor. 7. Water power is being used to drive a dynamo. 8. When being rubbed, some substances produce electric charges. 9. Nuclear fuel is undergoing nuclear fission. 10. The energy lost in the capacitor appears in the form of heat being generated in the dielectric.

Ex. 2. Match the fragments of the sentences. Then translate paying
It consists of a dc voltage source, a voltmeter, some wire, an ammeter,
they aren’t connected at the crossing
point unless a heavy black dot is placed where the two lines meet.
That’s a little less than the voltage
and a calibrated, wide-range potentiometer.
Suppose this potentiometer is set to 100 Ω,
also called the rule of significant digits.
After that, you can convert the calculated current, voltage, or resistance value to
dissipated by the potentiometer? The total power consumed

Five resistors of values R1through R5,
and replace it to get the lights working again.
When two conductor lines cross,
the total resistance is equal to the resistance of any one component divided by the number of components.
Competent engineers and scientists go by the rule of significant figures,
produced by a flashlight cell.
The interdependence among current, voltage, and resistance in dc circuits is called Ohm’s Law,
and the measured current is 10 mA.

Ex. 3. Translate into English using participles.
1. Это приведет к тому, что через каждую из оставшихся лампочек будет
протекать больший ток, и довольно скоро еще одна лампочка перегорит из-за переизбытка тока. 2. На каждой из лампочек в этой цепи, поскольку они одинаковые, произойдет одинаковое падение напряжения. 3. Подсчитывая мощность электроэнергии в цепи, содержащей последовательно подсоединенные резисторы, вам нужно только выяснить силу тока (I), которая идет по цепи. 4. Тогда мы бы наблюдали иллюзию ЭДС (электродвижущей силы), добавляющую или забирающую напряжение. 5. Счетчик показывает одно и тоже, независимо от того, думаете ли вы об измерении напряжения батареи Е или об измерении суммы напряжений Еn в последовательной цепи сопротивлений. 6. Также помните, что вам необходимо использовать такие единицы измерения, как вольт, ом и ампер при подсчетах. 7. Их легко проглядеть, но они могут повлечь за собой большие ошибки в повторяющихся процессах, где необходимы вычисления, производимые снова и снова.8. Если добавить новые цепи, предполагая, что источник электроэнергии справится с нагрузкой, это не повлияет на условия, существующие в предыдущих цепях. 9. На практике оптимальные значения зависят от того, каким образом была составлена цепь.

3.8.2 The gerund
Active
Passive
Indefinite
doing
being done
Perfect
having done
having been done
The gerund is a non-finite form of the verb. Gerunds are formed from verbs by adding -ing: be – being; work – working; design – designing. Gerunds can be formed from most verbs (except modal verbs).
Forms of the gerund
The simple active form and the passive form usually express an action that is simultaneous with the action expressed by the main verb. The perfect form and the perfect passive form express an action that precedes the action expressed by the main verb. The simple form of the gerund is the most common. The compound forms of the gerund are used more rarely, mostly in writing. Gerunds can be used in different functions in sentences (the subject, the object, part of the predicate, etc.). Gerunds are often used with prepositions in the function of adverbial modifiers.
Exercises
Ex. 1. Find the gerunds in the following sentences. Define their function. Translate the sentences into Russian.
1. In this course, the idea is to familiarize you with schematic symbols by getting you to read and use them in action.2. Remember Ohm’s Law for finding voltage. 3. Certainly, shorting out one of the resistances cannot cause the battery voltage to change. 4. Let’s use the four-significant-digit values to avoid the possibility of encountering the rounding-off bug. 5. The second method involves finding the net resistance R of the parallel combination. 6. When a voltage divider network is designed and assembled, the resistance values should be as small as possible without causing too much current drain on the battery or power supply. 7. The reason for choosing the smallest possible resistances is that, when the divider is used with a circuit, you do not want that circuit to upset the
