In Martin Luther King's speech "I Have a Dream" Which parts are weak and need to be improved? I hope you can please help me,...

I agree with the earlier posting - there is very little,
if anything, to criticise about this speech. Many teachers and academics use it as an
exemplar to illustrate technique, delivery, effect and social impact. King did deliver
some speeches which were less successful - in one using the metaphor of abortion to a
church gathering - but this one is excellent.

I would ask
your teacher which techniques s/he considers exemplify a good speech and find examples
of these from the text. There is no shortage of repetition, assonance, alliteration,
anecdote, use of personal pronouns, emotive language, imagery and metaphor to name just
a few. I would be interested what criticisms could be levelled at this
work.
