The first vowel in a word with an open syllable is pronounced as an alphabetical letter. As in "fine". The first "i" is pronounced as "i". But it doesn't work in "hello."
It says an open syllable is a syllable which ends with a vowel. If the open syllable is stressed the vowel is said as the letter of the alphabet. But why do they give the word "fever" I don't understand. This word and other words with it aren't open syllable words.

It also says the same rule applies to the words above.The "e" is not pronounced, but the syllable is open.
In the open syllable vowels are pronounced differently except the "o" as in "zero".
Is the "o" related exception related to the word "hello"?
'Fine' isn't an example of an open syllable. It's an example of the vowel-consonant-e syllable type (alternately called 'bossy e', 'magic e', 'sneaky e', 'silent e' or various other cutesy mnemonic terms).
'Hello' is comprised of two syllables - a closed syllable (hel) and an open syllable (lo).
There are six basic syllable types in English (although some break the double vowels down into two for a total of seven):
1. Open - no consonant on end, vowel is long.Examples: me, and the second syllable in hello2. Closed - ends with a consonant, has a short vowel sound.
Example: cat, hit, pot3. Vowel-Consonant-E (aka silent e, sneaky e, bossy e, etc.) - just as the pattern says, it's a vowel followed by a constant ending in the letter 'e'.
Examples: fine,cake,Pete4. Vowel team - two vowels work together to produce one vowel sound.
Examples: steam, boil5. R-controlled - the letter r follows a vowel, and colors/controls/influences the vowel sound to where it's neither long nor short.
Examples: star, cord,skirt6. Consonant-L-E - as the pattern says, the word ends with a consonant followed by the letter L and a final E.
Examples:table, bubble, circle
Some people make a distinction with the fourth pattern, and separate the diphthongs (two vowels blending into a new sound such as boil, loud) from the digraphs (two vowels making one sound such as meat, float) into a seventh syllable type. I'm not going to argue for or against that, but simply mention it so you're aware why you may see a list of seven syllable types instead of six.
All of those words have an open syllable, (type 1 on my list), followed by a closed syllable (type 2). You have to look at each syllable in a word, and apply the appropriate rule. The pronunciation rules govern only individual syllables, not the entire word (unless it's a one-syllable word).
It's not the same rule. None of those are open syllables. Those are all examples of the silent e (type 3) rule.
'Zero' is comprised of two open syllables, and rule 2 on my list applies to both of them, just as it does to the 2nd syllable in 'hello'.
I think your confusion may be a result of not looking at each individual syllable and recognizing that a multi-syllabic word may be comprised of different syllable types.
