;;在字母这一板块有一定难度的，应该是字母读音分类的内容了，尤其是含A音的字母与含/e/的字母，学生最不容易辨别。为此，教师在教或复习这一内容时不防采用儿歌的形式辅助于其中，收效会很好。儿歌可编为：英语字母有二十六，元音字母有五个，辅音字母二十个，半元音是Y。字母A 有四姐妹A H J K；字母E有八兄弟E B C D G P T V；字母I有两兄妹I Y；字母U有三兄弟U Q W；音素/e/有七个伙伴F L M N S X Z； 这种以儿歌形式的记忆方法，不仅增强了字母学习的趣味性，也使学生在有趣的氛围中不知不觉地记住了所要记的内容。 ;;字母需大写的情况 1.句子开头字母要大写. 2.人名,地名,国名以及表示某国语言的名词开头字母必须大写. 3.普通名词不大写,但由普通名词构成的专有名词要大写. 4.I, OK永远要大写. 5.位于姓名前的称呼等也必须大写.;;;; 板块二——语音 ;然而 我们又不能一味地让学生借助于这一拐杖，否则他们在英语学习上将永远是个瘸腿。为此，在语音复习阶段，老师应该将小学书中出现的所有单词就读音上进行了总结与概括，从中给学生归纳出许多字母以及字母组合的发音规则，并一一地让学生识记。如字母L只有两种发音，放在词首的发清晰的/l/，放在词末或le则发模糊/l/；字母Y一般有三种发音，放在词首的发/j/,在单音节词中发/ai/,在大多数双音节词中发/i/；字母组合ea一般也有三种发音，大多数发/i:/，如：clean, teacher, please;有的发/e/，如：head, sweater, breakfast; 还有的发/ei/, 如：great, break.小学英语中只有这两个单词中ea发/ei/；th一般有两种发音，小学阶段，发/θ / 音的大多与数字有关再加上mouth, think, thank等词，发/ D /音的大多与代词有关。诸如此类的发音规则通过老师地讲解与学生的识记，不仅使学生在做类似于单词辨音的操作题时正确率大增，同时也使学生在没有音标的扶持下读准单词音，即获得了见词能读的能力，为他们今后的英语学习打下了良好的基础。;;Vowels;Long vowel / i: / ;Long vowel / i: /;Short vowel /i/;Short vowel /i/;常见的题型： 1． 根据音标写出单词及词义如：/keik/ __________ __________2． 下列每组词中，那一个划线字母的发音与另外三个不一样如??1.
