Open syllables can be divided into absolute open syllables and relative open syllables.
(1) Absolute open syllable: refers to a syllable composed of a vowel phoneme without a consonant phoneme, such as: we, hi, yo-yo.
(2) Relatively open syllables: refers to a vowel phoneme followed by a consonant phoneme (except R), and finally a silent e letter, such as: take, make.
In the first syllable, this vowel sounds like the letter itself, such as hi|hai|, use|ju:z|.
Closed syllables: syllables consisting of vowels followed by consonants (except consonants R), such as leg and cross.
2) syllables can be divided into stressed syllables and unstressed syllables according to stress.
Stressed syllables: refers to the syllables with particularly loud pronunciation in disyllabic or polysyllabic words, marked with the stress symbol`, and other syllables are unstressed syllables, such as begin |be'gin|. Monosyllabic words are stressed, but not stressed.
