Alice: I like many foods. so I will presentation about my favorite foods.
>>I like a lot of food, so I will tell you about my favorite foods.
*I think you just need to rephrase your sentence, I noticed that you used words that you think has the same meaning to what you want to say but there more appropriate words for what you want to say.

Alice: first, I like fish.it taste very great.
>>First, I like fish. It tastes great.
*Always check the proper capitalization of the letters. You always start your sentences with a capital letter of the first word you are writing.

Alice: second, I like hams. ham's taste is similar to fish.
>>Second, I like ham. Ham taste similar to fish.
*Again, be mindful with the proper capitalization of the words then, there is not word "hams". Ham is considered plural so no need to put s at the end of the word. Also on your follow up sentence, you just have to remove the be-verb is because ham is used as a plural noun.

Alice: finally, I like bread. I like jam sandwich. and donuts. They are so sweet and yummy.
>>Finally, I like bread. I like jam sandwich and donuts. They are so sweet and yummy.
*So again, check your capitalizations and always double check where you put periods.

Alice: This is my favorite foods. thank you for listening my presentation.
>>These are my favorite foods. Thank you for listening to my presentation.
*You are talking about plural nouns which is foods so it should be these not this. "These are" are used for plural nouns and "This is" are for singular nouns. Then check you capitalization again.
