3. Protect your computer against viruses.
This sentence is already complete and doesn't need any changes.
4. I get my teeth checked at the dentist's every six months.
In this sentence, we can replace the phrase "at the dentist's" with the word "my" to make it shorter. So, the combined sentence would be: "I get my teeth checked every six months."
5. A mobile phone was lost on the train this morning.
To combine these sentences, we need to change the verb form from "lost" to "was lost" to indicate that the action happened to something. So, the combined sentence would be: "A mobile phone was lost on the train this morning."
6. The radio was invented by Marconi.
To combine these sentences, we need to transform the active sentence "Marconi invented the radio" into a passive sentence. In passive voice, the subject of the active sentence becomes the object. Additionally, the verb form changes from past simple to past participle ("invented" to "was invented"). So, the combined sentence would be: "The radio was invented by Marconi."
7. Shut your computer down when you aren't using it.
This sentence is already complete and doesn't need any changes.
8. The laptops have been put back in the cupboard by the students.
To combine these sentences, we need to transform the active sentence "The students have put the laptops back in the cupboard" into a passive sentence. In passive voice, the subject of the active sentence becomes the object. Additionally, the verb form changes from present perfect to present perfect passive ("have put" to "have been put"). So, the combined sentence would be: "The laptops have been put back in the cupboard by the students."
