Passive voice is most of the time used in a written form specilly if we have to write reports on research.
Remember that in passive voice we focus on the object or receiver of the action and not in the doer of the action.
Complete exercises 6a and 6c. Post your answers as a comment.


Exercise 6a
ResponderBorrar1. The tissue surface was rinsed with ice-cold isotonic saline solution by me.
2. The suspension was diluted to 100 ml with water by the scientist, after incubation at 37°C for 60 minutes.
3. Particles as small as 10 micrometers are filtered out by a mesh.
4. The audiometric thresholds at six frequencies from 250 Hz to 8 kHz is measured.
5. Densitometry was used to analyse the autoradiograph.
Exercise 6c
-Passive verbs: is encapsulated, is internalised, was used, is caught, was extracted, were diluted, was grind, was rinsed, is liberated.
-Formal sentences:
To do this, the surface of the tube was coated with a chemical receptor.
If we want to target a tumour which overexpresses folic acid, then folate receptors are attached to the surface of the nanotube.
And then, the drug is encapsulated in the tube.
Radioactive dust would be filtered out by devices in the two chimneys.
- Don´t need to be changed: want, use, can´t escape, dissolves, condenses, stains, fuse.
