附：音节小议
英语的音素分为元音和辅音两大类，由一个元音或一个元音加一个或几个辅音结合构成的语音单位叫做音节。例如：
由一个元音构成的音节：I /aI/“我”、oh / u/“哦”、a/eI， /“一个”、ear/I /“耳朵”等；
由一个元音加一个辅音构成的音节： bee/bi:/“蜜蜂”、ill /il/“生病”、my/mai/“我的”、see /si:/“看见”等；
由一个元音加几个辅音构成的音节：bed /bed/“床”、bag/b g/“袋子”、clock /kl k/等。
英语的词有一个音节的，也有两个音节或三个音节以上的。顾名思义，一个音节叫做单音节，两个音节叫做双音节，三个或三个以上的音节叫做多音节。例如good /gud/只有一个音节，所以叫做单音节词；morning/`m :nI /分别有/m :n/和/I /两个音节，所以叫做双音节词；而afternoon /`a:ft `nu:n/有/a:f/、/t /、/nu:n/三个音节，所以，叫做多音节词。
在英语中，双音节或多音节的单词，每一个词都有一个读得特别响亮的音节，叫做重读音节，重读音节以重读符号“`”来表示。例如在evening /`i:vni /一词中，/i:/是重读音节。一般来说，只有一个音节的单词往往重读，但通常不标重读符号；双音节词和多音节词至少有一个音节重读，并在重读的音节左上方标出重读符号。
音节分为开音节和闭音节。以元音字母a 或 e, i, o, u结尾的音节叫做开音节，如nice, hi, hello, fine等都是以开音节结尾的单词；以辅音字母结尾的音节叫做闭音节，如meet, bed, what, wall, mom等都是以闭音节结尾的单词。
1.记单词的最好办法是什么？ 把一个单词造出多个句子，训练把这多个句子在场景下脱口说出。句子记住了，单词也当然得到了充分理解和长期记忆。
2.学习英语忌过分讲究速度和效率，不愿花时间经常重复（复习）已学过的内容。语言运用是一种技能，技能则只有靠熟能生巧，要不断重复才会熟练，只有熟练了才会形成一种不假思索的技能。
3.语言是有声的，我们对语言的感受首先是语言的声音作用于我们的大脑。如果不练习听力，只是默默地阅读和背单词，其结果不仅听不懂别人讲外语，而且阅读水平也难以提高。
4.语言的实践性很强，如果只学而不用，就永远也学不好。我们学语言的目的就是为了应用，要学会在用中学习，这样才能提高兴趣，达到好的学习效果。
