I have a question I am confused I am not sure to find the place of the stress in a sentence.It is a really important task.Please help me the ESOL teachers.
There are 6 sentences
1.He telephoned the police yesterday
2.Can you show me the diamonds?
3.Paul has gone to the theatre
4.Have you heard about Marcella?
5.She's won €50.000 on the lottery
6.I'm not doing anything this evening

Where is the stress in these sentences?Only one word we have to underline.I thought that without hearing the sounds it is really difficult.And the reason of choosing is important also.I thought that €50.000 is important BECAUSE iT is THE amount to emphasize it.But I am not sure for all the 6 sentences.Please immediately help me in a right way.Thank you from now
