Tom studied last night.

[mampwamp]

Tom studied last night.
Tom was studied last night.

What is the different between senteces above. Are them correct?

 

[HugoJ]

Not a teacher.

The second one means that someone/something has studied Tom last night.

 

[Matthew Wai]

Tom might be a patient studied by doctors last night.

Not a teacher.

 

[Tdol]

You'd probably say that Tom was examined by doctors last night.

With the original question, the first is correct. The second is unlikely to be correct in most contexts.

 

[Matthew Wai]

Is it possible that Tom was studied by medical students last night?

 

[Boris Tatarenko]

Not a teacher nor a native speaker.
That sounds quite strange to me. I'd avoid it.

 

[HugoJ]

Maybe he meant :
"he was studying last night" he studied and is possibly still studying currently

Just a guess.

I'm not a teacher.

Does the sentence "Tom was studied up" make any sense?

 

[emsr2d2]

No. What did you think it might mean?

 

[Matthew Wai]

Maybe he meant :
"he was studying last night" he studied and is possibly still studying currently

If he meant so, he should say "he has been studying since last night".

Not a teacher.

Does the sentence "Tom was studied up" make any sense?

Not to me.It could be used colloquially and people would be able to guess the meaning, but it'snot a standard phrase I have come across, at least not in BrE.

You could come up with a context where was studied is possible in a medical context, but not with medical students IMO. It might be OK with a rare and unknown disease.
