26个字母中有5个纯元音字母（A E I O U），20个纯辅音字母。字母Y为半元音字母，当Y位于词首时为辅音字母，位于词中或词尾时为元音字母，其读音与字母I相同。掌握五个元音字母的读音及其组合规律是学好英语的关键。元音字母在单词中可以单独发音，也可以跟其它字母构成字母组合一起发音，常见的组合有：
一、五个元音字母在重读开音节与重读闭音节的读音
1.元音字母Ａ
１）在重读开音节中读字母音[ei ]
例如：name [neim] grade [greid] eraser [i'reisə] cake [keik] same [seim]table ['teibl] late [leit] favourite ['feivərit] face [feis] tape [teip] plane [plein] potato [pə'teitəu] skate [skeit] make [meik] lake [leik] take [teik] save [seiv] station ['steiʃən] baker ['beikə] place [pleis] tomato[tə'meitəu] safe [seif] gate [geit] snake [sneik] cage [keidʒ] baby ['beibi] paper ['peipə] famous ['feiməs] later ['leitə] radio ['reidiəu] patient ['peiʃənt]

2).在重读闭音节中读字[e]
例如：ten [ten] spell [spel] pen [pen] desk [desk] egg [eg] welcome ['welkəm] let [let] address [ə'dres] dress [dres] next ['nekst] leg [leg] empty ['empti] mend [mend] chess [tʃes] rest [rest] letter ['letə] better['betə] left [left] tell [tel] remember [ri'membə] invent [in'vent] December [di'sembə] wet [wet] message ['mesidʒ]
３.元音字母Ｉ

在英文中，5个元音字母分别为：a[ei]、e[i:]、i[ ai]、o[eu]、u[ju:]。元音发音时声带震动、气流通过口腔不受阻碍。元音分为单元音和双元音，单元音发音时唇形和舌位不变。双元音发音时由一个元音向另一个元音。
例如：six [siks] think [θiŋk] picture ['piktʃə] twin [twin] with [wið] drink [driŋk] chips [tʃip] swim [swim] sing [siŋ] dinner ['dinə] dish [diʃ] trip [trip] winter ['wintə] pick [pik] lift [lift] village ['vilidʒ]
４.元音字母Ｏ
１）在重读开音节中读字母音[əu]
例如：no [nəu] hello [hə'ləu] home [həum] those [ðəuz] over ['əuvə] phone [fəun] open ['əupən] so [səu] nose [nəuz] broken ['brəukən] robot ['rəubɔt] code [kəud] close [kləuz] smoke [sməuk] October [ɔk'təubə] hope [həup] ago [ə'gəu] Rome [rəum] suppose [sə'pəuz] mobile ['məubil] notice ['nəutis]
２）在重读闭音节中读[ɔ]
５.元音字母Ｕ
１）在重读开音节中读字母音[j u:]
例如：computer[kəm'pju:tə] excuse [iks'kju:z] student ['stju:dənt] use [ju:z] music ['mju:zik] usually ['ju:ʒuəli] refuse [ri'fju:z] human ['hju:mən] produce [prə'dju:s] scuba ['skju:bə] contribution [，kɔntri'bju:ʃən] pupil ['pju:pl] universe ['ju:nivə:s] huge [hju:dʒ] duty ['dju:ti]
２）在重读闭音节中读[ʌ]
例如：number ['nʌmbə] plus [plʌs] cup [kʌp] bus [bʌs] much [mʌtʃ] us [ʌs] husband ['hʌzbənd] uncle ['ʌŋkl] must [mʌst] lunch [lʌntʃ] hundred ['hʌndrəd] hungry ['hʌŋgri] jump [dʒʌmp] run [rʌn] fun [fʌn] discuss [di'skʌs] pumpkin ['pʌmpkin] summer ['sʌmə] duck [dʌk] subject ['sʌbdʒikt] suddenly ['sʌdnli]
英语的5个元音字母分别是a,e,i,o,u。
二、五个元音字母分别与字母Ｒ组合（ar、er、ir、or、ur）在重读音节的读音
a、e、i、o、u。第一类，元音字母，一共有五个，分别是a,e,i,o,u。第二类，辅音字母20个，第三类，是半元音字母，只有一个字母y。英语重5个元音字母分别为:a[ei]、e[i:]、i[ai]、o[eu]、u[ju:]。发元音。
１）.ＡＲ读[a:]
例如：sharpener ['ʃɑ:pənə] car [kɑ:] dark [dɑ:k] arm [ɑ:m] card [kɑ:d] park [pɑ:k] hard [hɑ:d] farmer ['fɑ:mə] party ['pɑ:ti] artist ['ɑ:tist] garden ['gɑ:dn] far [fɑ:]

a，e，i，o，u。英语的26个字母分两种类型：一种叫元音字母，另一种叫辅音字母。元音字有：a，e，i，o，u五个，其余为辅音字母。元音字母在重读开音节、重读相对开音节中发长音，在重读闭音节中发短音。美国的西班牙。
三、ar、er、ir、or、ur分别与字母Ｅ组合的读音
英语五个元音字母如下：英语的5个元音字母分别为：a、e、i、o、u，元音发音时声带震动，气流通过口腔不受阻碍。元音并非在所有的语言中都与元音字母一一对应，一些元音字母的组合也可以表示特殊的元音。比如汉语中的某些复韵母。
1）字母ARE组合读[ɛə]
例如：careful ['kɛəfəl] software ['sɔftwɛə]
2）字母ERE组合读 [ɛə]/[ iə]
