一、 音素
1、單元音：
2、雙元音：
3、清、濁輔音：
二、語音的基本常識
1、音節的劃分
一個單詞的音標中有幾個元音就有幾個音節。
2、重讀音節
任何雙音節或多音節單詞的音標中，有重讀音節和非重讀音節 ，哪一個音節重讀，該音節的左上方或該音節的元音上方標有重讀符號“'”。
3、濁化音
以sp__, st___, sk___開頭的單詞清輔音/p/ /t/ /k/分別要發濁輔音/b/ /d/ /g/。
4、定冠詞the的讀音
e.g. the man
c.f. the old man
5、不完全爆破
爆破音[p] [b] [t] [d] [k] [g] 后面緊跟另一個爆破音時，前面的那個爆破音只在口腔內形成阻礙，而不能完全讀出。
e.g. basketball
the part of the earth
6、連讀
在一個短語或句子中，如果相鄰兩詞的關系相等密切，而前一個詞以輔音結尾，后一個詞以元音開頭，輔音和元素連在一起讀。
7、意群的停頓
對于一個較長的句子，可以根據意思和結構將其劃分成幾群,一個意群必須一口氣說完。 關于語音的幾個概念
1) 字母：語言的書寫形式。元音字母a, e, i(y), o, u,
2) 音標：詞的語音形式。
3) 音素：音的最小的單位。英語中有48音素。
4) 音節：由元音和輔音構成的發音單位。
ap'ple, stu'dent, tea'cher, un'der'stand
5) 元音：發音響亮，是樂音；口腔中氣流不收阻礙；是構成音節的主要音。英語中有20元音。
6) 輔音：發音不響亮，是噪音；口腔中氣流受到阻礙；不是構成音節的主要音。中有28輔音。
7) 開音節：a) 輔音+元音+輔音+e name bike home due; b) 輔音+元音 he, go, hi
8) 閉音節：a) 輔音+元音+輔音 bad, bed, sit, hot, cup; b)元音+輔音it
