1. We should be thankful if you send the latest data of your experiment.

2. If there were no difference of potential between two points of a conductor, electrons would not continiue to flow.

3. If helium were obtained only from the air, it would be a rare gas.

4. So that an electric current may flow through the circuit, it is necessary that there be an electro-motive force acting in the circuit.

5. They could have done it if they had obtained the necessary equipment.

6. Whatever you should say, I would insist on greater voltage to be used in this case.

7. Whenever valve be removed from the cylinder, the interior should be thoroughly inspected.

8. It would have been impossible to cope with these difficulties if it had not been for the preparatory work, carried out by our scientists.

9. Were the molecules separated slightly, the force between them would be attractive.

10. It is required that all measurments be done beforehand.

11. It is necessary that a force be applied to the moving body to maintain motion.

12. They recommended that laboratory tests be conducted before the system be installed in the plane.

13. Put down the rule lest you should forget it.

14. I wish the data were more exact. We could figure out all the possible variants.

15. The engineer ordered that all spare parts be inspected carefully.

16. He wished he had made such solution – the reaction could have been quite different.

17. It is unlikely that they should use this alloy.

18. Had the piezo electric effec not been discovered, we could not have improved the operation.

19. Were the vegetation restored, the siol itself would be able to begin a cycle of regeneration, but tis constructive process would require centuries.

20. But for the luminosity of this substance it would be difficult to detect its properties.
