Process:
The phonetics are the gold key to study English. It 's very important for the students to learn English. So we should spend enough time to teach them to learn the knowledge freely. Before learning , we should make clear about the following knowledge. 音素：人说话的声音是由若干单个的音组成的，即使是一个很短的字、词也是由一定的读音组成的。英语把组成一个读音的最小单位叫音素。
音标：音标是记录音素的符号。英语音标就是记载英语字母和单词的读音的符号。英语国际音标共48个音素．其中元音音素
20 个，辅音音素28 个。
元音音素：发音时声带振动，呼出的气流通过口腔时不受阻碍，这样
形成的语音，称为元音。
辅音音素：不论声带振动与否，发音时呼出的气流通过口腔或鼻腔
时
受到一定的阻碍，这样形成的语音称为辅音。
前元音
：
/i:/ /i/ /e/ /? /
中元音
：/? / /?：/ /? /
后元音
：/a:/ /?/ / ?: / /?/ /u:/

1) 英语单词是由字母组成的。字母构成音节。有的单词包含一个音节，有的包含两
个，三个或更多的音节，分别为单音节词和双音节词和多音节词。单音节词单
独存在的时候，一般重读，不加重读符号。多音节和双音节词，都有一个读的
较响亮的音节，即重读音节，由重音符号标示。
2) 音节的分类---- 开音节，闭音节
开音节：以一个元音字母结尾，或在辅音字母后有一个辅音字母和一个不发音
的e，这样的重读音节称为开音节。闭音节：以一个辅音字母结尾的重读音节
称为闭音节。
Step3.practice: 区分开音节和闭音节
观察元音字母在开闭音节的发音规律
take map
he desk
hi six
hole lot
cute bus 元音字母在开音节中发字母本身音。
Aa/e?/ Ee /i:/ Ii/a ?/ Oo/?u/ Uu/ju:/
元音字母在闭音节中发短音。
Aa/?/ Ee /e/ Ii/?/ Oo/?/ Uu/?/
