(i) the phonemes /p/, /t/, /k/, /n/, /w/, /l/, /m/, /f/ (and insome dialects, a quick /j/) can only be preceded by /s/, and not by any otherconsonant; conversely, /s/ can only precede these consonants, and not others,e.g., /*sb/, /*sv/, /*sh/, etc. (note: /sf/ is verylimited in productivity, mainly appearing in technical terminology. Themost common example is sphere and its various related words. /sv/ appears insvelte, which is a loanword from French.)
(ii)/ɹ/ can only follow /p/, /b/, /t/, /d/, /k/, /ɡ/, /f/,/v/, /ʃ/, and /θ/, in a consonant cluster, and not others. (note: /vr/ is so unproductive that it only appears in vroom,an onomatopoeia.)
(iii)not allthree-consonant clusters can appear insyllable-initial position, but only/s/^voiceless plosive^/l/ or /r/, e.g., scream /skɹiːm/, splay /spleɪ/,strange /stɹeɪnʤ/, spring /spɹɪŋ/, etc
(iv)/ŋ/ never appears after long vowels or diphthongs
(v)/ʧ/, /ʤ/, and /ð/ do not cluster
(vi)/ɹ/, /w/, and /l/ only occur alone, or in a clusterfollowing another consonant
(vii)/h/, /w/, and /j/ do not appear in syllable-finalposition
(viii)/ɛ/, /æ/, /ɒ/, /ʌ/, /ɪ/, and /ʊ/ have to be followed byanother phone
(ix)/ʊ/ cannot appear at syllable-initial position
(x)/ʒ/ cannot appear at the beginning of a word except inloanwords, e.g., genre
英语中的连读主要有四种:1)辅音+元音的连读(Consonant + Vowel)2)辅音+辅音的连读3)元音+元音的连读4)T, D, S 或 Z + Y的连读这里是一个连读的例子。在这个例子里,不仅仅有连读的存在,还包含发音的一些变化,请仔细分辨:书写英语:They tell me that I’m easier to understand.口语连读:theytellme thedaimeasier der-undersdand。
