Inversion in sentences with unreal conditions

1. Study the structure of the sentences.

1. Were the value any bigger, space would expand so quickly that the universe would lack the structures that life requires. In a way, then, our very existence predicts the low value of the constant.

2. This straightforward technique might already be in common use, were it not for the draw backs associated with light-sensitive materials.

3. Had that material been maintained in the atmosphere it would have been more than enough to offset all the global warming expected this century.

4. This straightforward technique might already be in common use. were it not for the draw backs associated with light-sensitive materials.

2. Work out the rule.

Inversion can be used in sentences with real / unreal condition.

Practice

1. Sentences to be translated.

1. If one were able to move information or matter from one point to another faster than light, then according to special relativity, there would be some inertial frame of reference in which the signal or object was moving backwards in time.

2. If superintelligent aliens appeared and claimed credit for creating life on earth (or even particular species), the purely evolutionary explanation would be cast in doubt. But no one has yet produced such evidence.

3. The classic example of a problem involving causality is the "grandfather paradox": what if one were to go back in time and kill one's own grandfather before one's father was conceived?

4. Such position is not shared by the elected leaders of New Mexico — if it were, the arguing would be over by now.

5. If the assembly were cooled merely by air, the metal surrounding the nuclear material would melt; it might even burn.

6, Einstein pointed out that many anomalous experiments could be explained if the energy of a Maxwell Ian light wave were localized into point-like quanta that move independently of one another, even if the wave itself is spread continuously over space.

7. If we restrict the computer to functioning at a cold temperature, if we find a way to let it get hot, we could improve that by a factor of another 100 million.

8. It would be fascinating if there were a halo of dark matter around Earth, just as there are the Van Allen belts, or rings around Saturn,

2. Decide whether the condition in the following sentences is real or unreal.

3. Translate the sentences.

4. If everyone told everyone else the truth, relationships would descend into chaos.

5. So if a utility's customer base expanded or customers used more electricity then expected, it was to the benefit of a company's bottom line.

6. If the mass were reduced by a factor of more than about 10, nuclei could be made not just of protons and neutrons but also of other baryons containing strange quarks.

7. If customers used less electricity than expected, utilities failed to recover their capital costs, let alone secure money for profits or to invest in future projects.

8. If this estimate is supported by radioactive-dating tests soon to be undertaken at the University of California, the skull is the oldest yet discovered of the tool-making man.

9. If an event horizon has an extreme but finite spacetime curvature and gravity, how can there be any path between a low-gravity and curvature region and a singularity without passing through a horizon?

10. If the mass of the quarks were changed so that the neutron became 2 percent heavier than the proton, no long-lived form of carbon or oxygen would exist.

11. During the 1980s, many analysts thought industrial robotics would take off

12. If one were to see the night sky as a black wall and expect the technology race to screech to a polite halt, then it would be natural to fear that long-lived people would be a burden on the poor, crowded world of our children.
