9. Запомните:

В английском языке страдательный залог – the Passive Voice – образуется при помощи вспомогательного глагола to be в соответствующем времени, лице и числе и причастия II смыслового глагола.

Глагол в страдательном залоге в английском языке может переводиться на русский язык:

1) формой глагола в страдательном залоге: The letter was written. – Письмо было написано.

2) неопределенно-личным предложением: I was asked. – Меня спросили.

3) формой возвратных глаголов на -ся, -сь: Petrol is also used as a solvent.
- Бензин также используется как растворитель.

Страдательный залог употребляется во всех временных формах Indefinite и Perfect (Present, Past, Future), но он имеет только две формы Continuous (Present и Past).

Indefinite Continuous Perfect

Present I am asked I am being asked I have been asked

Past I was asked I was being asked I had been asked

Future I shall be asked - I shall have been asked

Переведите следующие предложения, обращая внимание на перевод страдательного залога:

1. When these oil products have been distilled off, there remains a viscous black liquid called residual oil. 2. Petrol is used as fuel for internal combustion engines; the principal two grades are aviation petrol and motor fuel, which are used for aircraft and motor cars respectively. 3. Petrol is also used as a solvent for oils and rubber. 4. Kerosene is used as fuel for tractors. 5. In the absence of electricity kerosene is used for lighting. 6. They are used to lubricate different engines.
7. Lubricants are thus divided into automobile oil, aircraft oil, etc. 8. After the lubricants have been distilled off from the residual oil there remains a non-volatile dark mass called oil tar, which is used as a road binder. 9. Residual oil is subjected to chemical processing to produce petrol and is used as a liquid furnace fuel. 10. From some grades of petroleum it is also possible to prepare a mixture of solid hydrocarbons, which is known as paraffin wax. 11. This is used to make candles.
12. There is also a mixture of liquid and solid hydrocarbons that is known as vaseline. 13. Commercial vaseline is used to grease metal goods. 14. Purified vaseline is used in medicine as a base for ointments.

10. Переведите на русский язык, обращая внимание на перевод сказуемых, выраженных глаголом в страдательном залоге:
