初中英語音標課件

  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,

  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
